Abstract

The engineer's vice is fabricated from rolled steel channel sections, for coarse and fine adjustment of the mobile jaw. Its base comprises a pair of rails connected by a welded toe strap, fixed to a bench by a bolt through the strap or by flange clips. The fixed jaw bridges rails at one end, sited over a cross bar locating the lever-operated screw. A screw driven slide fits between rails which also guide the mobile jaw. Rebated plates welded transversely across the flange ends may secure a jaw to the rails, the coarse adjustment of the jaw being effected by a pin engaging slide web holes. The pin may be mounted on a pivotable plate secured in a fork by an axle pin.

Description

La présente invention concerne un étau en profils paralèlles pour des travaux sur établis ou sur machines. The present invention relates to a vice in parallel profiles for work on workbenches or machines.

Dans les étaux connus généralement sous l-e nom d'étaux d'établis, ces étaux ont les inconvénients suivants s la vis est toujours de la même longueur, ce qui implique pour l'ouverture des machines d'innombrables tours du manillon, pour déplacer celle-ci vers l'avant ou vers l'arrière
De plus, pour améliorer la stabilité de ces étaux d'établis, généralement t.nt leur corps est supporté par l'établi et seul le manillon de serrage déborde de l'établi, ce qui présente une difficulté pour une pièce vertical.In vices generally known as bench vices, these vices have the following drawbacks s the screw is always the same length, which implies for the opening of machines countless turns of the pin, to move that - forward or backward
In addition, to improve the stability of these workbench vices, generally their body is supported by the workbench and only the tightening pin projects beyond the workbench, which presents a difficulty for a vertical workpiece.

La pressente invention à pour but de remédier è tous ces inconvénients
L'étau en profils parallèles selon l'invention se caractérise en ce qu'il comporte un socle chemin de guidage), fixé sur la face supérieure d'un établi par exemple au moyen d'une vis centrale, comme dans le cas d'étau tournant, et qu'il est pourvu d'un chemin de guidage sur lequel est montée coulissante une mâchoire mobile. Le dit chemin de guidage (socle) se prolonge vers l'arrière de l'établi, la fixation s'effectue sur le socle è l'aide de brides, et d'un boulon central visse dans le trou filtré 24.The present invention aims to remedy all these drawbacks
The vice in parallel profiles according to the invention is characterized in that it comprises a base guide path), fixed on the upper face of a workbench for example by means of a central screw, as in the case of rotating vice, and that it is provided with a guide path on which a movable jaw is slidably mounted. The said guide path (base) extends towards the rear of the workbench, the fixing is carried out on the base using flanges, and a central bolt screws into the filtered hole 24.

Une rainure suplémentaire dans l'établi, où loge la vis centrale, permet d'avancer et de reculer l'étau, et facilite le serrage verticale. An additional groove in the workbench, where the central screw is housed, allows the vice to move forward and back, and facilitates vertical tightening.

L'invention pourra, de façon, être bien comprise i l'aide du compldment de déscription qui suit, ainsi que des dessins ci-annexés. The invention can, therefore, be clearly understood with the aid of the following description supplement, as well as of the appended drawings.

Lesquels compléments et dessins sont relatifs è un mode de réalisation préféré de l'invention et ne comportent bien entendu aucun caracthre l'immitatif. Which complements and drawings relate to a preferred embodiment of the invention and of course do not include any characteristic.

L'étau en profil parallèle peut Autre monté de la même façon sur machine.The object of the invention:
- Fig. 1 represents a general view,
- Fig. 2 shows a section along AA in FIG. 1,
- Fig. 3 represents a view from below, of FIG.
- Fig. 4 represents a side view, the fit ure 1
- Fig. 5 shows a section along BB of Figure 4
The vice in parallel profile can Other mounted in the same way on machine.

è l'aide des brides, que sur établis. using the clamps, only on workbenches.

Avec référence de la figure 5, l'étau comprend un socle allongé 20/21 iixé sur la face supérieure d'un établi. With reference to FIG. 5, the vice comprises an elongated base 20/21 attached to the upper face of a workbench.

Au centre arrière de la machoire 4 tFig.2) sont soudée deux pattes 5 entre ces deux pattes se loge une plaque mâle 6 assemblée par un axe de liaison 7. A l'extrémité de la plaque nivale 6 est soudé un t8ton-de blocage 8
La partie inférieur de ce têton 8 est en partie usinée en pente. Le têton de blocage 8 pivote autour de l'axe 7, lorsque la machoire 4 est poussée vers l'avant. In the rear center of the jaw 4 tFig.2) are welded two legs 5 between these two legs is housed a male plate 6 assembled by a connecting pin 7. At the end of the level plate 6 is welded a t8ton-blocking 8
The lower part of this pin 8 is partly machined on a slope. The locking pin 8 pivots about the axis 7, when the jaw 4 is pushed forward.

La machoire avant 2 est soudée sur le socle 20/21 entre ce socle
figure une crémaillère 9, qui est perforée de trous espacés sur toute la
longueur.The front jaw 2 is welded to the base 20/21 between this base
is a rack 9, which is perforated with holes spaced over the entire
length.

La mâchoire arrière 4 coulisse sur le bâti constituant le socle 20/21
de l'étau, faisant chemin de guidage par l'intermédiaire des plaques de coulisses 18 de la crémaillère 9, de la machoire 4 et des brides de fixation 22.The rear jaw 4 slides on the frame constituting the base 20/21
of the vice, making a guide path by means of the slide plates 18 of the rack 9, the jaw 4 and the fixing flanges 22.

L'opération de serrage est la suivante ; la mâchoire 4 est reculée à l'aide de la main, on introduit la pièce à serrer, on avance la mâchoire 4 Jusqu'd ce qu'elle bute contre la pièce. The tightening operation is as follows; the jaw 4 is moved back using the hand, the part to be clamped is introduced, the jaw 4 is advanced until it abuts against the part.

On actionne le manillon 1 qui se loge dans la bague de mamoeuvre 10, l'action de la vis 14 en liaison par filtage avec l'écrou 15 par l'assemblage de la pièce 16 fait avancer la crémaillère 9, le toton de blocage 8 s'encastre dans un des trous 23 le plus proche, et îa pièce est au stade de serrage. The crank pin 1 which is housed in the movement ring 10 is actuated, the action of the screw 14 in threading connection with the nut 15 by the assembly of the part 16 advances the rack 9, the locking stud 8 fits into one of the nearest holes 23, and the part is in the tightening stage.

La vis du dit dispositif de serrage se loge entre les bagues de butées 11 et 13 avec la vis de blocage 3, qui elle sert au démontage de la vis 14. The screw of said clamping device is housed between the abutment rings 11 and 13 with the locking screw 3, which is used to disassemble the screw 14.

Ainsi le manillon n'intervient qu'd la fin da serrages et en raison de la faible longueur de la vis 14 son déplacement maximal dans le sens longitudinal reste très faible. Thus the pin only intervenes at the end of tightening and due to the short length of the screw 14, its maximum displacement in the longitudinal direction remains very small.

Quelque soit la longueur necessaire de étau dans la construction la longueur de la vis 14 sera toujours de l'ordure des 150 mm pour l'immobilisation des pièces i travailler0
Les mNchoires 2 et 4 de l'étau en profil peuvent entre munies de mors traités. Whatever the necessary length of vice in the construction the length of the screw 14 will always be of the order of 150 mm for the immobilization of the parts i to work0
The jaws 2 and 4 of the vice in profile can between provided with treated jaws.
