Description

Procédé d'indexation en position sur le sol de machine ou similaire et pied de machine faisant application.Method of indexing in position on the machine floor or the like and machine foot applying.

L'invention concerne un procédé d'indexation en position sur le sol de machine ou similaire, tel qu'une machine-outil ou encore un robot de soudage, ainsi qu'un pied de machine faisant application.The invention relates to a method of indexing in position on the machine floor or the like, such as a machine tool or even a welding robot, as well as an application machine foot.

ARRIERE-PLAN DE L'INVENTION Un pied de machine conforme à l'état de la technique est illustré en coupe sur la figure 1 annexée. La machine 1 comporte un châssis avec un socle qui repose sur le sol généralement en béton par l'intermédiaire de pieds tels que celui illustré qui comporte une douille 4 vissée sur le socle de la machine et saillant sous celui-ci. La douille 4 a une extrémité inférieure qui est reçue dans un évidement conique 3 d'une semelle 2 fixée au sol par des vis de fixations non représentées et dont la fonction est de répartir la pression sur le sol pour éviter de poinçonner celui-ci. La douille 4, après avoir été vissée/dévissée jusqu'à réglage correct du niveau de la machine 1, est bloquée sur le socle de la machine 1 au moyen d'un con- tre-écrou 5. La coopération de l'extrémité inférieure de la douille 4 et de l' évidement conique 3 de la semelle 2 permet, sous l'effet du poids de la machine 1, un alignement automatique de l'axe de la douille 4 sur l'axe de l' évidement conique 3, réalisant ainsi une indexation en position de la machine 1 sur le sol. La semelle 2 comporte un orifice taraudé 6 au centre de l' évidement conique 3 pour recevoir l'extrémité d'un tirant 7 dont l'autre extrémité porte un écrou 8 d'ancrage qui est serré contre l'extrémité supérieure de la douille 4, empêchant ainsi la machine de se soulever, par exemple sous l'effet de vibrations ou d'un déport de masse hors du polygone de sustentation de la machine due au mouvement d'une partie mobile de celle-ci. Un tel pied de machine présente l'inconvénient de nécessiter un accès à la semelle pour pouvoir fixer celle-ci au sol. On peut tout d'abord, comme cela est illustré à la figure 1, disposer les pieds sous des parties en saillie du socle de la machine, ce qui déporte les semelles par rapport au socle et permet un accès aisé à celles-ci. Mais ces parties en saillie forment des obstacles empêchant une disposition accolée des socles de machines adjacentes . Selon une autre disposition, les pieds s'étendent directement sous le socle, ce qui évite l'inconvénient précité. Dans ce cas, la machine étant préalablement équipée des douilles 4 sur lesquelles la semelle 2 est retenue au moyen du tirant 7 et de l'écrou 8, il faut, après avoir mis en place la machine, repérer la position au sol des semelles, déplacer la machine en en désolidarisant les semelles, fixer ces dernières au sol dans la position précédemment repérée, et replacer la machine 1 en position sur les semelles. Ce type d'installation est d'une mise en œuvre longue et complexe, et nécessite de nombreuses manipulations de la machine au moyen d'engins de levage de dimensions importantes adaptées à la masse et à l'encombrement de la machine. Pour éviter ces nombreuses manipulations, il est connu de prévoir dans le socle de la machine une pluralité de passages qui s'étendent chacun en regard d'un des orifices de la semelle destinés à recevoir une vis de fixation de celle-ci sur le sol. Ces passages permettent la réalisation dans le sol de perçages dans le prolongement des orifices de la semelle destinés à recevoir les vis de fixation sans déplacer la machine, au moyen d'un foret introduit par le passage dans l'orifice de la se- melle (typiquement quatre vis de fixation par semelle, soit quatre perçages par semelle) . Néanmoins, ces nombreux passages compliquent la conception de la machine et la fragilise. En outre, lors du positionnement de la machine, il faut impérativement veiller à ce que la semelle ne tourne pas de sorte que les orifices des vis de fixation restent en alignement des passages dans le socle. La mise en œuvre de ce procédé est rendue difficile par le fait que les vis de fixation doivent être posées en aveugle au fond d'un passage pouvant présenter une longueur importante.BACKGROUND OF THE INVENTION A machine foot according to the state of the art is illustrated in section in attached FIG. 1. The machine 1 comprises a frame with a base which rests on the ground generally made of concrete by means of feet such as that illustrated which comprises a socket 4 screwed on the base of the machine and projecting under it. The sleeve 4 has a lower end which is received in a conical recess 3 of a sole 2 fixed to the ground by fixing screws not shown and whose function is to distribute the pressure on the ground to avoid punching it. The socket 4, after having been screwed / unscrewed until the machine level 1 has been correctly adjusted, is locked on the base of the machine 1 by means of a lock nut 5. The cooperation of the lower end the sleeve 4 and the conical recess 3 of the sole 2 allows, under the effect of the weight of the machine 1, automatic alignment of the axis of the sleeve 4 on the axis of the conical recess 3, thus performing an indexing in position of the machine 1 on the ground. The sole 2 has a threaded orifice 6 in the center of the conical recess 3 to receive the end of a tie rod 7 the other end of which carries a nut 8 for anchoring which is tightened against the upper end of the sleeve 4 , thus preventing the machine from lifting, for example under the effect of vibrations or of a mass offset out of the support polygon of the machine due to the movement of a movable part thereof. Such a machine foot has the drawback of requiring access to the sole in order to be able to fix it to the ground. We can first of all, as illustrated in Figure 1, arrange the feet under protruding parts of the base of the machine, which offset the soles relative to the base and allows easy access to them. However, these projecting parts form obstacles preventing an adjoining arrangement of the bases of adjacent machines. According to another arrangement, the feet extend directly under the base, which avoids the aforementioned drawback. In this case, the machine being previously equipped with the sockets 4 on which the sole 2 is retained by means of the tie rod 7 and the nut 8, it is necessary, after having set up the machine, to locate the position on the ground of the soles, move the machine by separating the soles, fix the latter to the ground in the position previously identified, and replace the machine 1 in position on the soles. This type of installation is a long and complex implementation, and requires numerous manipulations of the machine by means of lifting devices of large dimensions adapted to the mass and size of the machine. To avoid these numerous manipulations, it is known to provide in the base of the machine a plurality of passages which each extend opposite one of the orifices of the sole intended to receive a screw for fixing the latter on the ground. . These passages allow the production in the ground of holes in the extension of the orifices of the sole intended to receive the fixing screws without moving the machine, by means of a drill bit introduced by the passage in the orifice of the sole ( typically four fixing screws per sole, or four holes per sole). However, these numerous passages complicate the design of the machine and weaken it. In addition, when positioning the machine, it is imperative to ensure that the soleplate does not rotate so that the orifices of the fixing screws remain in alignment with the passages in the base. The implementation of this process is made difficult by the fact that the fixing screws must be placed blind at the bottom of a passage which may have a considerable length.

OBJET DE L'INVENTION L'invention a pour objet un procédé d'indexation en position sur le sol de machine ou similaire qui évite les inconvénients précités, ainsi qu'un pied de machine spécialement prévu pour la mise en œuvre de ce procédé.OBJECT OF THE INVENTION The subject of the invention is a method of indexing in position on the machine floor or the like which avoids the aforementioned drawbacks, as well as a machine foot specially provided for the implementation of this method.

BREVE DESCRIPTION DE L'INVENTION L'invention a plus précisément pour objet un pro- cédé d'indexation en position sur le sol de machine ou similaire équipée d'un pied avec une douille creuse de réglage de niveau vissée sur la machine et en appui sans glissement sur une semelle en contact avec le sol qui comporte un orifice débouchant dans la douille, le procé- dé comportant les étapes de positionner la machine sur le sol, de réaliser dans le sol un perçage dans le prolongement de l'orifice de la semelle à l'aide d'un outil de perçage introduit dans la douille et dans l'orifice de la semelle, et de mettre en place dans le perçage ainsi réa- lise un organe de positionnement qui coopère avec l'orifice de la semelle pour indexer celle-ci en position sur le sol . Contrairement aux procédés connus, le procédé de l'invention ne nécessite donc qu'un seul perçage pour in- dexer la semelle, et donc la douille et la machine, en position sur le sol. Le perçage étant réalisé sensiblement dans l'axe de la douille, il importe peu que la semelle ait ou non tourné lors du positionnement de la machine . Le procédé de l'invention est très simple et rapide à mettre en œuvre (un perçage par pied) , et ne nécessite aucune manipulation de la machine autre que son positionnement définitif. Selon un mode particulier de mise en œuvre du procédé de l'invention, l'organe de positionnement est fixé au sol, de préférence par scellement. La fixation au sol de l'organe de positionnement permet son utilisation non seulement comme organe d'indexation, mais également comme organe d'ancrage au sol de la machine, par exemple en r-apportant sur une extrémité filetée de celui-ci un écrou. d'ancrage retenant la douille au sol. L'invention a également pour objet un pied de machine faisant application, comportant une douille creuse avec un fond formant semelle, le fond comportant un ori- fice pour coopérer avec un organe de positionnement saillant du sol. Il est en effet avantageux de prévoir un fond intimement solidaire de la douille, plutôt qu'une semelle séparée, ce qui évite tout à la fois le risque de perte et le risque de mauvais positionnement de la semelle lors de la mise en place de la machine. A l'instar de la semelle, le fond aura une surface suffisante pour assurer la transmission au sol du poids de la machine sous une pression acceptable. Selon un mode de réalisation préféré, le fond est réalisé intégralement avec la douille. Selon une disposition particulière, l'organe de positionnement est fixé au sol et a une extrémité libre filetée pour recevoir un écrou d'ancrage de la douille qui prend appui sur une face interne du fond de la douille .BRIEF DESCRIPTION OF THE INVENTION The subject of the invention is more precisely an indexing method in position on the ground of a machine or the like equipped with a foot with a hollow level adjustment socket screwed onto the machine and in support without sliding on a sole in contact with the ground which has an orifice opening into the socket, the method comprising the steps of positioning the machine on the ground, of carrying out in the ground a drilling in the extension of the orifice of the sole using a drilling tool inserted into the sleeve and into the hole in the sole, and to place in the hole thus produced a positioning member which cooperates with the hole in the sole to index it in position on the ground. Unlike the known methods, the method of the invention therefore requires only a single bore to index the sole, and therefore the sleeve and the machine, in position on the ground. The drilling being carried out substantially in the axis of the sleeve, it matters little whether or not the sole has rotated during positioning of the machine. The method of the invention is very simple and quick to implement (drilling by foot), and does not require any manipulation of the machine other than its final positioning. According to a particular embodiment of the method of the invention, the positioning member is fixed to the ground, preferably by sealing. The fixing to the ground of the positioning member allows its use not only as an indexing member, but also as an anchoring member to the ground of the machine, for example by bringing a nut on a threaded end thereof. . anchor retaining the socket to the ground. The invention also relates to a machine foot making application, comprising a hollow socket with a base forming a sole, the base comprising an orifice for cooperating with a positioning member projecting from the ground. It is indeed advantageous to provide a bottom that is intimately secured to the sleeve, rather than a separate sole, which avoids both the risk of loss and the risk of improper positioning of the sole when the machine. Like the sole, the bottom will have sufficient surface to transmit the weight of the machine to the ground under acceptable pressure. According to a preferred embodiment, the bottom is made integrally with the socket. According to a particular arrangement, the positioning member is fixed to the ground and has a threaded free end to receive a nut for anchoring the sleeve which bears on an internal face of the bottom of the socket.

BREVE DESCRIPTION DES DESSINS La description détaillée de l'invention ci- dessous fait référence, outre à la figure 1 déjà décrite, à la figure 2 qui est une vue en coupe d'un pied de machine selon l'invention, illustré après mise en œuvre du procédé de l'invention. DESCRIPTION DETAILLEE DE L'INVENTION Sur la figure 2, la machine 100 comporte un socle dont on aperçoit une partie de la structure sous la forme d'une poutre en I . Le socle est équipé de pieds tels que celui illustré qui comporte une douille 104 vissée sur l'aile inférieure de la poutre en I . La douille 104 comporte une extrémité inférieure qui présente un fond 102 réalisé intégralement avec la douille et directement en appui sur le sol. Le fond 102 forme une semelle intégrée à la douille, ce qui permet d'économiser une pièce et évite le risque de perte ou de mauvais positionnement de la semelle par rapport à la douille lors de la mise en place de la machine. En variante, le fond peut ne pas être intégral avec la douille, mais rapporté sur celle-ci de façon à lui être intimement solidaire, par exemple par collage ou soudure. Le fond comporte un orifice central 106 débouchant dans la douille 104. La machine 100 munie de ses pieds est tout d'abord mise en place sur le sol dans la position définitive désirée. Une fois la machine positionnée, on règle le niveau de la machine 100 par rapport au sol en vissant/dévissant les douilles 104, puis les douilles 104 sont chacune bloquées sur la machine 100 à l'aide d'un contre-écrou 105. Selon l'invention, on réalise alors dans le sol un perçage 112 dans le prolongement de l'orifice 106 au moyen d'un foret 110 (représenté en pointillés) introduit dans la douille 104 et dans l'orifice 106. L'orifice 106 fait alors office de guide pour le foret 110. A cet effet, la poutre de la machine comporte un passage 111 sur son aile supérieure pour permettre le passage du foret 110. Il est à noter que si la poutre en I supporte un plancher, le plancher comportera également un passage en regard de la douille 104, le passage dans le plancher pouvant être ensuite obturé par une trappe. On peut, afin d'améliorer le guidage du foret 110, prévoir un guide supplémentaire sur l'aile supérieure du I. Dans le perçage 112 ainsi réalisé, on rapporte un tirant 107 de sorte que celui-ci s'étende au travers de l'orifice 106. Le tirant 107 est fixé dans le perçage 112, par exemple ici par scellement à l'aide de mortier- colle. La mise en place du tirant 107 est facilitée par le fait qu'il comporte une extrémité libre qui est largement en saillie du fond de la douille 104 à l'intérieur de celle-ci, permettant une préhension aisée du tirant 107 lors de sa mise en place. Le tirant 107 a, au moins au niveau de l'orifice 106, un diamètre ajusté au diamètre de l'orifice 106 de sorte que le tirant 107 joue le rôle d'organe de posi- tionnement de la douille 104, et donc de la machine 100, en indexant celle-ci sur le sol dans une position définie par le tirant 107 lui-même. Une fois le tirant 107 définitivement scellé, on visse sur l'extrémité libre filetée du tirant 107 un écrou 108 qui prend appui sur une face interne du fond 102, directement, ou, comme illustré, par l'intermédiaire d'une rondelle d'appui. Le tirant 107 et l' écrou 108 empêchent ainsi la douille 104 de se soulever du sol, de sorte que la machine 100 n'est plus seulement indexée, mais ancrée au sol. Il est à noter que le procédé de l'invention peut être rais en œuvre avec le pied de machine de l'état de la technique illustré à la figure 1. Pour ce faire, après avoir mis en position une machine équipée d'un tel pied, on retire l' écrou 8 et le tirant 7, on réalise dans le sol un perçage dans le prolongement de l'orifice 6 de la semelle 2 au moyen d'un foret introduit dans la douille 4 et l'orifice 6, et on fixe dans ce perçage un nouveau tirant, similaire au tirant 107 du pied de l'invention, qui coopère alors avec l'orifice 6 pour indexer la semelle 2 en position sur le sol. L'indexation en position de la semelle 2 entraîne, par la coopération conique de la semelle 2 et la douille 4, l'indexation de la douille 4, et donc de la machine. De préférence, ce nouveau tirant pré- sente une extrémité libre filetée de longueur suffisante pour saillir de la douille, afin d'y rapporter un écrou d'ancrage de la douille qui prend appui sur l'extrémité supérieure de la douille 4 pour ancrer la machine au sol. La mise en œuvre du procédé de l'invention ne né- cessite donc pas une douille avec un fond intégral ou rapporté, bien que, comme expliqué, il soit plus avantageux d'utiliser un fond intimement solidaire de la douille. Le tirant peut être fixé au sol par d'autres pro- cédés qu'un scellement, comme par exemple en étant vissé dans une cheville de fixation rapportée dans le perçage. Si l'on est intéressé uniquement par l'indexation en position sans pour autant rechercher l'ancrage, le tirant pourra alors être choisi ^longueur réduite mais néan- moins suffisante pour coopérer avec l'orifice de la semelle, ou du fond faisant office de semelle. Dans ce cas précis, il n'est pas nécessaire de fixer le tirant au sol, qui peut simplement être glissé à ajustement ou à force dans le perçage. BRIEF DESCRIPTION OF THE DRAWINGS The detailed description of the invention below refers, in addition to Figure 1 already described, to Figure 2 which is a sectional view of a machine foot according to the invention, illustrated after setting work of the process of the invention. DETAILED DESCRIPTION OF THE INVENTION In FIG. 2, the machine 100 comprises a base of which a part of the structure can be seen in the form of an I-beam. The base is equipped with feet such as the one illustrated which includes a socket 104 screwed onto the lower wing of the I-beam. The sleeve 104 has a lower end which has a bottom 102 made integrally with the sleeve and directly in contact with the ground. The bottom 102 forms a sole integrated into the sleeve, which saves a part and avoids the risk of loss or incorrect positioning of the sole relative to the sleeve when the machine is put in place. As a variant, the bottom may not be integral with the sleeve, but attached to the latter so as to be intimately connected thereto, for example by bonding or welding. The bottom has a central orifice 106 opening into the socket 104. The machine 100 provided with its feet is first of all placed on the ground in the desired final position. Once the machine has been positioned, the level of the machine 100 is adjusted relative to the ground by screwing / unscrewing the sockets 104, then the sockets 104 are each locked on the machine 100 using a lock nut 105. According to the invention, a hole 112 is then made in the ground in the extension of the orifice 106 to the by means of a drill 110 (shown in dotted lines) introduced into the socket 104 and into the orifice 106. The orifice 106 then acts as a guide for the drill 110. For this purpose, the beam of the machine has a passage 111 on its upper wing to allow the passage of the drill 110. It should be noted that if the I-beam supports a floor, the floor will also include a passage opposite the socket 104, the passage in the floor can then be closed by a hatch. It is possible, in order to improve the guidance of the drill 110, to provide an additional guide on the upper wing of the I. In the hole 112 thus produced, a tie rod 107 is added so that it extends through the orifice 106. The tie rod 107 is fixed in the bore 112, for example here by sealing with adhesive mortar. The establishment of the tie rod 107 is facilitated by the fact that it has a free end which protrudes widely from the bottom of the sleeve 104 inside thereof, allowing easy grip of the tie rod 107 when it is put in place. The tie rod 107 has, at least at the orifice 106, a diameter adjusted to the diameter of the orifice 106 so that the tie rod 107 acts as a positioning member for the sleeve 104, and therefore for the machine 100, by indexing it on the ground in a position defined by the tie rod 107 itself. Once the tie rod 107 is definitively sealed, a nut 108 is screwed onto the free threaded end of the tie rod 107 which bears on an internal face of the bottom 102, directly, or, as illustrated, by means of a washer support. The tie rod 107 and the nut 108 thus prevent the bush 104 from lifting from the ground, so that the machine 100 is no longer only indexed, but anchored to the ground. It should be noted that the method of the invention can be implemented with the machine base of the state of the art illustrated in FIG. 1. To do this, after having put in position a machine equipped with such a base, the nut 8 and the tie rod 7 are removed, a hole is made in the ground in the extension of the orifice 6 of the sole 2 by means of a drill bit introduced into the socket 4 and the orifice 6, and a new tie is fixed in this bore, similar to the tie 107 of the foot of the invention, which then cooperates with the orifice 6 to index the sole 2 in position on the ground. The indexing in position of the sole 2 causes, by the conical cooperation of the sole 2 and the sleeve 4, the indexing of the sleeve 4, and therefore of the machine. Preferably, this new tie has a free threaded end of sufficient length to protrude from the socket, in order to bring there an anchor nut for the socket which bears on the upper end of the socket 4 to anchor the machine on the ground. The implementation of the method of the invention therefore does not require a socket with an integral or added bottom, although, as explained, it is more advantageous to use a bottom intimately secured to the socket. The tie rod can be fixed to the ground by other methods than a seal, for example by being screwed into a fixing dowel added in the hole. If one is interested only in indexing in position without seeking anchoring, the tie may then be chosen ^ reduced length but nevertheless sufficient to cooperate with the orifice of the sole, or the bottom acting sole. In this case, it is not necessary to fix the tie rod to the ground, which can simply be slid to fit or force in the hole.
