Definitions
- the invention relates to a support device for motor assembly, for supporting complex and heavy elements, such as motors.
- Examples of such devices include assembly pallets for supporting and transporting, on an assembly line, motor vehicle engines.
- assembly pallet comprises a plate, to which are fixed candles, the candles forming vertical supports, having upper bearing surfaces of shape adapted to come there to pose additional bearing areas of a housing of engine. The engine is thus maintained in a fixed position relative to the plate under the effect of its weight.
- the upper support ends of the candles may typically have flat surfaces, intended to abut against opposing plane surfaces machined locally on the motor housing. Some candles may also include bearing pins, intended to be inserted into the corresponding centering holes of the motor housing.
- the same pallet can therefore include a first group of candles, intended to support a first model of engine, and a second group of candles to support another model of engine.
- candles of the second group which do not form also support for the first engine model, do not interfere with the engine. So we sometimes use trays with removable candles, or with candles mounted on a rotating base, so as to be able to position certain candles in a first position when they have to support the engine model to which they are dedicated, and so as to be able to position the candle in minus a second position, allowing the candle to support another engine model.
- the support device may further comprise a rotary base, rotatably mounted around the first candle, and carrying a height wedge secured to the rotary base so that the wedge comes, for a first angular position of the rotary base, to be superimposed over the support end of the second candle so as to enhance the support area provided by the second candle, and so that the hold can be released from the end of the second candle for a second position of the second candle rotary base.
- the rotary base is configured to use a cylindrical outer surface of the first candle as a rotational bearing surface. This avoids having to set up an axis of rotation specifically dedicated to the mobility of the base.
- the axis of the first candle is parallel to the axis of the second candle.
- the axes of the first candle and the second candle may for example be perpendicular to the same reference plane of the base.
- the height wedge secured to the rotary base is in a position spaced from both the first and the second candle, so as to leave free access to the ends of the two candles and the space between the two candles.
- the rotary base may comprise an annular portion surrounding the first candle, of height substantially less than the height of the first candle and the height of the second candle, and may comprise a leg extending at least partly vertically from the base rotating, and supporting the wedge height relative to the annular portion of the rotary base.
- candlelight is meant here a substantially vertical support element relative to a reference plane of the base, considered horizontal.
- the height of the rotary base is less than or equal to one third of the height of the first candle, and is less than or equal to one third of the height of the second candle.
- “height” is meant at a distance from the rotary base in the direction of support of the candles against the engine, bearing direction which generally corresponds to the vertical direction. In some particular cases, it may be possible to envisage using the device to exert a non-vertical holding pressure on well-chosen support zones of the engine, but it may, however, be necessary to block the motor between two supporting devices each in an opposite direction.
- the axis of the lug carrying the shim may be parallel to the axis of the first candle, and be configured to rotate about the axis of the first candle.
- the tab can form a sleeve surrounding the first candle, the sheath being configured to rotate about the axis of the first candle.
- the shim can then be connected to an upper portion of the sheath, for example by a radial connection portion, or by a connecting portion in an arc, this arcuate portion leaving clear the space between the first and the second candle when the second candle is covered by the hold.
- the wedge and the leg can be configured so that, during rotation of the base, the wedge comes to cover the second candle leaving the leg behind the second candle. Aft of the second candle is behind the candle in relation to the circular approach path of the hold towards the second candle. This leaves the gap between the first and second candles when the second candle is covered by the hold.
- the rotating base can carry a third candle, which is thereby movable relative to the first and second fixed candles.
- the wedge may optionally comprise two different heights, depending on the level of angular overlap of the second candle by the wedge.
- the second candle can thus be raised by two different heights according to the angular position of the base to which the wedge is connected.
- the hold covers the second candle if it is placed so as to raise a support zone of the second candle, even if the hold does not completely cover the upper part of the second candle.
- the top of the second candle may include a central pin, and the wedge may be split to engage around the piece.
- the first candle can be held on the base by a fixed base, the fixed base defining an upper face raised relative to the base.
- the rotary base may advantageously comprise a lower face placed on the upper face of the fixed base. The rotation of the rotary base is thus facilitated.
- the upper and lower faces may be planar, or may include indexing reliefs to facilitate the positioning and / or maintenance of the rotary base in predefined relative angular positions relative to the fixed base.
- the support device may comprise an elastic device configured to press the rotary base against the fixed base.
- the elastic device may for example develop a plating force between 1N and 10N, thus allowing the rotary base to be raised manually relative to the fixed base to place it in another angular position.
- a transport device for a motor assembly line comprising a support device as described above, and comprising a transportable tray forming the base of the support device.
- the transportable tray is for example able to be moved along a production line.
- An engine assembly pallet may for example comprise a plate, comprising a plate mounted parallel to the plate to rotate relative to the plate, the plate forming the base of a support device as described above.
- a motor assembly pallet referenced 20 comprises a transportable tray 13 on which is rotatably mounted a rotary plate 12, rotatable relative to the plate 13, so as to position the plate 12 at different angles with respect to a operator on one side of the pallet 20.
- the rotary plate 12 forms a base for a group of candles 1, 2, 3, 4, 5, 6, mounted thereon so as to protrude perpendicularly to the plate 12.
- the group of candles is erected vertically with respect to the upper face 10 of the plate 12.
- Each candle has an upper end, respectively 21, 22, 23, 24, 25, 26, configured to abut a complementary bearing area of a motor housing adapted to be supported by the assembly pallet 20.
- All candles are not configured to support the same motor.
- Some of the support ends are flat, for example 21, 22, 23, 25, and others comprise a bearing pin, for example here the ends 24, 26 respectively comprise a bearing pin 34 and a pin of support 36.
- some of the candles can see their radial size locally reduced by vertical flats, as is the case for example for the first candle 21 and the fifth candle 25.
- the pallet 20 illustrated in figure 1 comprises five fixed candles, namely the candles 1, 2, 4, 5, 6.
- the candles 1 and 2 are surrounded by the fixed base 11 raised with respect to the surface 10 of the plate 12.
- the candle 3 is rotatably mounted around the candle 1, via a rotary base 9 carrying the candle 3, and a lower face 15 bears on an upper face 14 of the fixed base 11 surrounding the base of the first candle 1.
- the candle 3 can be placed in a suitable first position to support the engine associated with it, or may be on the contrary excluded angularly from the first position to respect the size of another engine.
- the group of candles 1, 2, 3 is part of a support device 30 with a variable configuration, making it possible in particular to modify the configuration in the space of the support ends available at the ends of the candles 1, 2, 3 to support the one or the other engine intended to be placed on the pallet 20.
- the rotary base 9 supports, in addition to the candle 3, a height shim, reference 7, mounted on a substantially vertical carrying rod 8, so as to be able to superimpose the wedge 7 with the bearing zone 12 of the second candle, and to raise the potential height of support of this second candle.
- the displacement of the rotary base 9 makes it possible both to modulate the position of the candle 3 and to vary the angular position of the height block 7.
- the figure 2 illustrates, at a slightly different angle, a support device 30 similar to that of the pallet 20 of the figure 1 , the same elements being designated by the same references.
- the height wedge 7, during the rotation of the rotary base 9, moves along a circular trajectory 17.
- the carrier rod 8 is here positioned so as to remain in this path behind the wedge 7, especially when the shim 7 comes to cap the second candle 2.
- the space between the first candle 1 and the second candle 2 remains clear over the entire height of the candles, and we can, depending on the needs, insert a portion of the casing of an engine.
- the device 30 may comprise indexing elements, for example an indexing relief 18 visible on the figure 2 , designed for example to limit the rotation of the support 9 in a first direction of rotation.
- the indexing element 18 may for example form an angular stop blocking the base 9 in rotation.
- indexing elements for example a pin 28, also visible on the figure 2 .
- One or more indexing holes through the base 9 may be provided for the pin 28, and one or more indexing holes 29 passing through at least a portion of the height of the base 11.
- An elastic holding device 19 may be provided to press the rotary base 9 against the fixed base 11, and thus ensure stability of the relative angular position enter the base 9 and the base 11, even before the pin in place of the pin 28 .
- the elastic holding device 19 may comprise a spring sized to be countered manually, for example by lifting the base 9 relative to the base 11.
- the compression spring (not shown) may be arranged to exert a pressure spreading, depending on the vertical direction, the upper face 16 of the mobile base 9, relative to a bearing shoulder located above the base 9, for example integral axially with the first candle 1.
- the figure 3 is a top view of the device of the figure 2 illustrating two positions taken successively by the mobile base 9, a first position represented in dotted lines, and in which the height wedge is in a position 7 'superimposed axially on the candle 2. It is found on the figure 3 elements common to Figures 1 and 2 the same elements being designated by the same references. In this first position, the third candle occupies a position 3 'which is compatible with the size of the engine designed to be supported by the candle 2 and raised. The pin 28 and one of the holes 29 are designed to block the base 9 in this first position.
- a second position of the base 9 and elements attached thereto is shown in solid lines.
- the position shown is a transient position, allowing, by continuing the rotation of the base, to arrive for example to the angular position indexed by the shim 18, for which the third candle 3 is adequately placed to support a model of motor to which this spatial configuration of the candles is adapted.
- the height wedge 7 can be connected to the base 9 by a tab extending radially between the first candle and the wedge, or at least intercepting, higher than at the level of the base 9 itself, the radial plane passing through the axes of the two candles.
- the rotating base 9 can support a shim height 7 without carrying a third candle 3, or can instead support two or more candles.
- the shapes of the upper parts of the candles may vary depending on the support zones provided on the engines to be supported, and may comprise for example flat supports, blades, dihedrons, pawns.
- the shape of the hold can be provided to preserve the geometry of the support zone, or to modify the geometry of the support zone.
- the support device makes it possible to increase the versatility of the assembly pallets, and makes it possible to use each pallet for more varied engine configurations to be assembled.
- the device allows to adapt at an affordable cost, an existing pallet, by adding a new support configuration adapted to an engine model not originally planned.
- the device makes it possible to put into production a new engine geometry by reusing already available tools.
- the device according to the invention makes it possible to reduce the manufacturing cost associated with the production tools, to limit the overall size of the production tools of a factory, and to reduce the number of references to be managed with regard to the tools.

Description
L'invention a pour objet un dispositif support pour assemblage de moteur, destiné à soutenir des éléments de forme complexe et lourds, tels que des moteurs. Comme exemple de tels dispositifs, on peut citer les palettes d'assemblage permettant de supporter et de transporter, sur une chaîne de montage, des moteurs de véhicule automobile. Typiquement, une telle palette d'assemblage comporte un plateau, auquel sont solidarisées des chandelles, les chandelles formant des supports verticaux, comportant des surfaces supérieures d'appui de forme adaptée pour venir y poser des zones d'appui complémentaires d'un carter de moteur. Le moteur est ainsi maintenu en position fixe par rapport au plateau sous l'effet de son poids.The invention relates to a support device for motor assembly, for supporting complex and heavy elements, such as motors. Examples of such devices include assembly pallets for supporting and transporting, on an assembly line, motor vehicle engines. Typically, such an assembly pallet comprises a plate, to which are fixed candles, the candles forming vertical supports, having upper bearing surfaces of shape adapted to come there to pose additional bearing areas of a housing of engine. The engine is thus maintained in a fixed position relative to the plate under the effect of its weight.
Les extrémités supérieures d'appui des chandelles peuvent typiquement comporter des surfaces planes, destinées à s'appuyer sur des surfaces planes antagonistes usinées localement sur le carter du moteur. Certaines chandelles peuvent également comporter des pions d'appui, destinés à venir être insérés dans des orifices de centrage correspondant du carter du moteur.The upper support ends of the candles may typically have flat surfaces, intended to abut against opposing plane surfaces machined locally on the motor housing. Some candles may also include bearing pins, intended to be inserted into the corresponding centering holes of the motor housing.
On souhaite dans la mesure du possible utiliser une même palette pour assembler plusieurs modèles de moteur. Une même palette peut donc comporter un premier groupe de chandelles, destiné à soutenir un premier modèle de moteur, et un deuxième groupe de chandelles destiné à soutenir un autre modèle de moteur.If possible, it is desirable to use the same pallet to assemble several engine models. The same pallet can therefore include a first group of candles, intended to support a first model of engine, and a second group of candles to support another model of engine.
Il faut bien sûr que, lorsque le premier modèle de moteur est en place, des chandelles du second groupe, qui ne forment pas également support pour le premier modèle de moteur, ne viennent pas interférer avec le moteur. On utilise donc parfois des plateaux avec des chandelles amovibles, ou avec des chandelles montées sur un socle rotatif, de manière à pouvoir positionner certaines chandelle dans une première position lorsqu'elles doivent soutenir la modèle de moteur auquel elles sont dédiées, et de manière à pouvoir positionner la chandelle dans au moins une deuxième position, permettant à la chandelle de soutenir un autre modèle de moteur.Of course, when the first engine model is in place, candles of the second group, which do not form also support for the first engine model, do not interfere with the engine. So we sometimes use trays with removable candles, or with candles mounted on a rotating base, so as to be able to position certain candles in a first position when they have to support the engine model to which they are dedicated, and so as to be able to position the candle in minus a second position, allowing the candle to support another engine model.
A delà de ces palettes à chandelles rotatives, un besoin existe pour pouvoir développer des palettes aptes à supporter plus de deux types de moteur différents.Beyond these rotary candle pallets, a need exists to develop pallets able to support more than two different types of engine.
A cette fin, un dispositif support pour assemblage de moteur, notamment de moteur automobile, peut avantageusement comprendre :
- une base,
- au moins une première chandelle et une deuxième chandelle parallèle à la première chandelle, montées sur la base , chaque chandelle comportant une extrémité d'appui opposée à la base, l'extrémité d'appui étant apte à accueillir une zone d'appui d'un carter de moteur pour soutenir le poids du moteur en cours d'assemblage.
- a base,
- at least a first candle and a second candle parallel to the first candle, mounted on the base, each candle having a support end opposite to the base, the support end being adapted to receive a support zone of an engine crankcase to support the weight of the engine being assembled.
Le dispositif support peut comprendre en outre un socle rotatif, monté à rotation autour de la première chandelle, et portant une cale de hauteur solidarisée au socle rotatif de manière à ce que la cale vienne, pour une première position angulaire du socle rotatif, se superposer par-dessus l'extrémité d'appui de la deuxième chandelle de manière à rehausser la zone support offerte par la deuxième chandelle, et de manière à ce que la cale puisse être dégagée de l'extrémité de la deuxième chandelle pour une deuxième position du socle rotatif.The support device may further comprise a rotary base, rotatably mounted around the first candle, and carrying a height wedge secured to the rotary base so that the wedge comes, for a first angular position of the rotary base, to be superimposed over the support end of the second candle so as to enhance the support area provided by the second candle, and so that the hold can be released from the end of the second candle for a second position of the second candle rotary base.
Il est ainsi possible de passer d'une première configuration adaptée au maintien d'un premier modèle de carter, à une deuxième configuration dont les zones d'appui des chandelles, pour certaines surélevé(e)s par une ou plusieurs cales, pour d'autres non surélevées, sont adaptée pour soutenir un deuxième modèle de carter.It is thus possible to pass from a first configuration adapted to maintain a first crankcase model, to a second configuration including the candle support zones, for some raised by one or more shims, for other not elevated, are adapted to support a second crankcase model.
Avantageusement, le socle rotatif est configuré pour utiliser une surface extérieure cylindrique de la première chandelle comme surface d'appui de rotation. On évite ainsi d'avoir à mettre en place un axe de rotation spécifiquement dédié à la mobilité du socle.Advantageously, the rotary base is configured to use a cylindrical outer surface of the first candle as a rotational bearing surface. This avoids having to set up an axis of rotation specifically dedicated to the mobility of the base.
De manière préférentielle, l'axe de la première chandelle est parallèle à l'axe de la deuxième chandelle. Les axes de la première chandelle et de la deuxième chandelle peuvent par exemple être perpendiculaires à un même plan de référence de la base.Preferably, the axis of the first candle is parallel to the axis of the second candle. The axes of the first candle and the second candle may for example be perpendicular to the same reference plane of the base.
De manière avantageuse, pour au moins une deuxième position du socle rotatif, la cale de hauteur solidaire du socle rotatif, se trouve dans une position écartée à la fois de la première et de la deuxième chandelle, de manière à laisser libre l'accès aux extrémités d'appui des deux chandelles ainsi qu'à l'espace séparant les deux chandelles.Advantageously, for at least a second position of the rotary base, the height wedge secured to the rotary base, is in a position spaced from both the first and the second candle, so as to leave free access to the ends of the two candles and the space between the two candles.
Le socle rotatif peut comporter une portion annulaire entourant la première chandelle, de hauteur sensiblement inférieure à la hauteur de la première chandelle et à la hauteur de la deuxième chandelle, et peut comporter une patte s'étendant au moins en partie verticalement à partir du socle rotatif, et soutenant la cale en hauteur par rapport à la portion annulaire du socle rotatif.The rotary base may comprise an annular portion surrounding the first candle, of height substantially less than the height of the first candle and the height of the second candle, and may comprise a leg extending at least partly vertically from the base rotating, and supporting the wedge height relative to the annular portion of the rotary base.
Par chandelle, on entend ici un élément de soutien sensiblement vertical par rapport à un plan de référence de la base, considéré comme horizontal.By candlelight is meant here a substantially vertical support element relative to a reference plane of the base, considered horizontal.
Par sensiblement inférieure on entend ici que la hauteur du socle rotatif est inférieure ou égale au tiers de la hauteur de la première chandelle, et est inférieure ou égale au tiers de la hauteur de la deuxième chandelle. Par "en hauteur", on entend à distance du socle rotatif dans la direction d'appui des chandelles contre le moteur, direction d'appui qui correspond en général à la direction verticale. On peut, dans certains cas particulier, envisager d'utiliser le dispositif pour exercer une pression de maintien autre que verticale sur des zones d'appui bien choisies du moteur, il peut être cependant alors nécessaire de bloquer le moteur entre deux dispositifs de maintien appuyant chacun dans une direction opposée.By significantly lower is meant here that the height of the rotary base is less than or equal to one third of the height of the first candle, and is less than or equal to one third of the height of the second candle. By "height" is meant at a distance from the rotary base in the direction of support of the candles against the engine, bearing direction which generally corresponds to the vertical direction. In some particular cases, it may be possible to envisage using the device to exert a non-vertical holding pressure on well-chosen support zones of the engine, but it may, however, be necessary to block the motor between two supporting devices each in an opposite direction.
L'axe de la patte portant la cale peut être parallèle à l'axe de la première chandelle, et être configuré pour tourner autour de l'axe de la première chandelle.The axis of the lug carrying the shim may be parallel to the axis of the first candle, and be configured to rotate about the axis of the first candle.
Selon un autre mode de réalisation, la peut patte former un fourreau entourant la première chandelle, le fourreau étant configuré pour tourner autour de l'axe de la première chandelle.According to another embodiment, the tab can form a sleeve surrounding the first candle, the sheath being configured to rotate about the axis of the first candle.
La cale peut être alors reliée à une portion supérieure du fourreau, par exemple par une portion de liaison radiale, ou encore par une portion de liaison en arc de cercle, cette portion en arc de cercle laissant dégagé l'espace entre la première et la deuxième chandelle quand la deuxième chandelle est recouverte par la cale.The shim can then be connected to an upper portion of the sheath, for example by a radial connection portion, or by a connecting portion in an arc, this arcuate portion leaving clear the space between the first and the second candle when the second candle is covered by the hold.
La cale et la patte peuvent être configurées pour que, lors de la rotation du socle, la cale vienne recouvrir la deuxième chandelle en laissant la patte en arrière de la deuxième chandelle. Par en arrière de la deuxième chandelle, on entend en arrière de la chandelle par rapport à la trajectoire circulaire d'approche de la cale vers la deuxième chandelle. On laisse ainsi dégagé l'espace entre la première et la deuxième chandelle quand la deuxième chandelle est recouverte par la cale.The wedge and the leg can be configured so that, during rotation of the base, the wedge comes to cover the second candle leaving the leg behind the second candle. Aft of the second candle is behind the candle in relation to the circular approach path of the hold towards the second candle. This leaves the gap between the first and second candles when the second candle is covered by the hold.
De manière avantageuse, le socle rotatif peut porter une troisième chandelle, qui est de ce fait mobile par rapport à la première et à la deuxième chandelle fixes.Advantageously, the rotating base can carry a third candle, which is thereby movable relative to the first and second fixed candles.
Il est ainsi possible d'adapter la hauteur de la deuxième chandelle pour une première position angulaire du socle, en gardant la troisième chandelle en retrait par rapport au carter de moteur, puis de modifier, en plaçant le socle rotatif dans une autre position angulaire, la troisième chandelle pour la mettre à portée des zones d'appui du carter du moteur. D'autres positions de fonctionnement sont envisageables, plaçant la troisième chandelle à des positions angulaires différentes autour de la première chandelle, en gardant la deuxième chandelle découverte. La cale peut éventuellement comporter deux hauteurs différentes, en fonction du niveau de recouvrement angulaire de la deuxième chandelle par la cale. La deuxième chandelle peut ainsi être rehaussée de deux hauteurs différentes selon la position angulaire du socle auquel est liée la cale.It is thus possible to adapt the height of the second candle for a first angular position of the base, keeping the third candle recessed with respect to the motor housing, and then to modify, placing the rotary base in another angular position, the third candle to put it within reach of the bearing areas of the motor housing. Other operating positions are conceivable, placing the third candle at different angular positions around the first candle, keeping the second candle uncovered. The wedge may optionally comprise two different heights, depending on the level of angular overlap of the second candle by the wedge. The second candle can thus be raised by two different heights according to the angular position of the base to which the wedge is connected.
On considère que la cale recouvre la deuxième chandelle si elle est placée de manière à rehausser une zone d'appui de la deuxième chandelle, même si la cale ne recouvre pas entièrement la partie supérieure de la deuxième chandelle. Par exemple, le haut de la deuxième chandelle peut comporter un pion central, et la cale peut être fendue pour venir s'engager autour du pion.It is considered that the hold covers the second candle if it is placed so as to raise a support zone of the second candle, even if the hold does not completely cover the upper part of the second candle. For example, the top of the second candle may include a central pin, and the wedge may be split to engage around the piece.
Avantageusement, la première chandelle peut être maintenue sur la base par un socle fixe, le socle fixe définissant une face supérieure surélevée par rapport à la base. Le socle rotatif peut avantageusement comporter une face inférieure posée sur la face supérieure du socle fixe. La rotation du socle rotatif est ainsi facilitée.Advantageously, the first candle can be held on the base by a fixed base, the fixed base defining an upper face raised relative to the base. The rotary base may advantageously comprise a lower face placed on the upper face of the fixed base. The rotation of the rotary base is thus facilitated.
Les faces supérieure et inférieure peuvent être planes, ou peuvent comporter des reliefs d'indexage pour faciliter le positionnement et/ou le maintien du socle rotatif dans des positions angulaires relatives prédéfinies par rapport au socle fixe.The upper and lower faces may be planar, or may include indexing reliefs to facilitate the positioning and / or maintenance of the rotary base in predefined relative angular positions relative to the fixed base.
Le dispositif support peut comporter un dispositif élastique configuré pour plaquer le socle rotatif contre le socle fixe.The support device may comprise an elastic device configured to press the rotary base against the fixed base.
Le dispositif élastique peut par exemple développer une force de placage entre 1N et 10N, permettant ainsi de soulever manuellement le socle rotatif par rapport au socle fixe pour le placer dans une autre position angulaire.The elastic device may for example develop a plating force between 1N and 10N, thus allowing the rotary base to be raised manually relative to the fixed base to place it in another angular position.
Est également proposé un dispositif de transport pour chaîne de montage de moteurs, comprenant un dispositif support tel que décrit précédemment, et comportant un plateau transportable formant la base du dispositif support.Also provided is a transport device for a motor assembly line, comprising a support device as described above, and comprising a transportable tray forming the base of the support device.
Le plateau transportable est par exemple apte à être déplacé le long d'une ligne de production. Une palette d'assemblage de moteur peut par exemple comporter un plateau, comporter une plaque montée parallèle au plateau pour tourner par rapport au plateau, la plaque formant la base d'un dispositif support tel que décrit précédemment.The transportable tray is for example able to be moved along a production line. An engine assembly pallet may for example comprise a plate, comprising a plate mounted parallel to the plate to rotate relative to the plate, the plate forming the base of a support device as described above.

Tel qu'illustré sur la
Chacune des chandelles comporte une extrémité supérieure, respectivement 21, 22, 23, 24, 25, 26, configurée pour venir s'appuyer sur une zone d'appui complémentaire d'un carter de moteur conçu pour être supporté par la palette d'assemblage 20.Each candle has an upper end, respectively 21, 22, 23, 24, 25, 26, configured to abut a complementary bearing area of a motor housing adapted to be supported by the
Toutes les chandelles ne sont pas configurées pour supporter le même moteur. Certaines des extrémités d'appui sont plates, par exemple 21, 22, 23, 25, et d'autres comportent un pion d'appui, par exemple ici les extrémités 24, 26 comportent respectivement un pion d'appui 34 et un pion d'appui 36.All candles are not configured to support the same motor. Some of the support ends are flat, for example 21, 22, 23, 25, and others comprise a bearing pin, for example here the
En fonction de l'encombrement des moteurs à positionner sur les chandelles, certaines des chandelles peuvent voir leur encombrement radial localement réduit par des méplats verticaux, comme c'est le cas par exemple pour la première chandelle 21 et pour la cinquième chandelle 25.Depending on the size of the motors to be positioned on the candles, some of the candles can see their radial size locally reduced by vertical flats, as is the case for example for the
La palette 20 illustrée en
Le groupe de chandelles 1, 2, 3 fait partie d'un dispositif support 30 à configuration variable, permettant notamment de modifier la configuration dans l'espace des extrémités d'appui disponibles aux extrémités des chandelles 1, 2, 3 pour supporter l'un ou l'autre moteur prévu pour être posé sur la palette 20.The group of
Dans l'exemple illustré le socle rotatif 9 supporte, outre la chandelle 3, une cale de hauteur, référence 7, montée sur une tige porteuse 8 sensiblement verticale, de manière à pouvoir superposer la cale 7 avec la zone d'appui 12 de la deuxième chandelle, et à rehausser la hauteur potentielle d'appui de cette deuxième chandelle.In the example shown, the
Grâce à cette configuration, le déplacement du socle rotatif 9 permet à la fois de moduler la position de la chandelle 3 et de faire varier la position angulaire de la cale de hauteur 7.With this configuration, the displacement of the
La
Le dispositif 30 peut comporter des éléments d'indexage, par exemple un relief d'indexage 18 visible sur la
D'autres types d'éléments d'indexage sont envisageables, par exemple une goupille 28, également visible sur la
Un dispositif de maintien élastique 19 peut être prévu pour plaquer le socle rotatif 9 contre le socle fixe 11, et assurer ainsi une stabilité de la position angulaire relative enter le socle 9 et le socle 11, avant même la pise en place de la goupille 28.An
Le dispositif de maintien élastique 19 peut comprendre un ressort dimensionné pour être contré manuellement, par exemple en soulevant le socle 9 par rapport au socle 11. Le ressort de compression (non représenté) peut être disposé de manière à exercer une pression écartant, suivant la direction verticale, la face supérieure 16 du socle mobile 9, par rapport à un épaulement d'appui situé au dessus du socle 9, solidaire par exemple axialement de la première chandelle 1.The
La
Une seconde position du socle 9 et des éléments qui y sont rattachée, est représentée en trait plein. La position représentée est une position transitoire, permettant, en poursuivant la rotation du socle, d'arriver par exemple jusqu'à la position angulaire indexée par la cale 18, pour laquelle la troisième chandelle 3 est placée de manière adéquate pour soutenir un modèle de moteur auquel cette configuration spatiale des chandelles est adaptée.A second position of the
L'invention ne se limite pas aux exemples de réalisation décrits, et peut se décliner en de nombreuses variantes. Lorsque l'encombrement des moteurs à placer sur la palette 20 le permet, la cale de hauteur 7 peut être reliée au socle 9 par une patte s'étendant radialement entre la première chandelle et la cale, ou du moins interceptant, plus haut qu'au niveau du socle 9 lui-même, le plan radial passant par les axes des deux chandelles.The invention is not limited to the embodiments described, and can be declined in many variants. When the size of the motors to be placed on the
Le socle rotatif 9 peut supporter une cale de hauteur 7 sans porter une troisième chandelle 3, ou peut au contraire supporter deux chandelles ou davantage.The rotating
Les formes des parties supérieures des chandelles peuvent varier en fonction des zones d'appui prévues sur les moteurs à supporter, et peuvent comporter par exemple des appuis plats, des lames, des dièdres, des pions. La forme de la cale peut être prévue pour conserver la géométrie de la zone d'appui, ou pour modifier la géométrie de la zone d'appui.The shapes of the upper parts of the candles may vary depending on the support zones provided on the engines to be supported, and may comprise for example flat supports, blades, dihedrons, pawns. The shape of the hold can be provided to preserve the geometry of the support zone, or to modify the geometry of the support zone.
Le dispositif support selon l'invention permet d'augmenter la versatilité des palettes d'assemblage, et permet d'utiliser chaque palette pour des configurations plus variées de moteur à assembler. En outre, le dispositif permet d'adapter à moindres frais, une palette existante, en lui ajoutant une nouvelle configuration d'appui adaptée à un modèle de moteur non prévu initialement. Le dispositif permet de mettre en production une nouvelle géométrie de moteur en réutilisant des outillages déjà disponibles.The support device according to the invention makes it possible to increase the versatility of the assembly pallets, and makes it possible to use each pallet for more varied engine configurations to be assembled. In addition, the device allows to adapt at an affordable cost, an existing pallet, by adding a new support configuration adapted to an engine model not originally planned. The device makes it possible to put into production a new engine geometry by reusing already available tools.
Le dispositif selon l'invention permet de réduire le coût de fabrication lié aux outils de production, de limiter l'encombrement global des outils de production d'une usine, et de réduire le nombre de référence à gérer en ce qui concerne les outillages.The device according to the invention makes it possible to reduce the manufacturing cost associated with the production tools, to limit the overall size of the production tools of a factory, and to reduce the number of references to be managed with regard to the tools.
