Application to the machining of rough (unfinished) components.

Description

Butée de réaction pour outillage d'usinage.Reaction stop for machining tools.

La présente invention concerne une lutée de réaction pour outillage d'usinage. The present invention relates to a reaction lute for machining tools.

Les outillages d'usinage sont généralement constitués de butées et de brides, et ils ont pour but de maintenir rigidement des pièces à usiner afin d'éviter les vibrations dues à l'usinage. Machining tools generally consist of stops and flanges, and their purpose is to rigidly hold workpieces in order to avoid vibrations due to machining.

Les pièces doivent être soutenues là où elles sont bridées pour éviter toutes déformations lors du bridage. The parts must be supported where they are clamped to avoid any deformation during clamping.

Quand elles sont soutenues au niveau d'une face, ou d'un élément, brute de fonderie, cette face peut présenter des variations géométriques d'une pièce à l'autre. When they are supported on a face, or of an element, rough of foundry, this face can present geometrical variations from one part to another.

La présente invention a pour but d'absorber ces différences géométriques en utilisant comme soutien, au niveau du bridage, une butée de réaction qui s'adapte aux dimensions de la pièce à usiner. The present invention aims to absorb these geometric differences by using as support, at the clamping, a reaction stop that adapts to the dimensions of the workpiece.

La présente invention a pour objet une butée de réaction ccaractérisée en ce qu'elle comporte une cale mobile sous l'action d'un moyen élastique et sur laquelle s'appuie une pièce à usiner, et un piston bloquant la cale mobile, la cale et le piston coopérant par l'intermédiaire de deux plans inclinés. The present invention relates to a reaction stopcharacterized in that it comprises a movable block under the action of an elastic means and on which a workpiece is supported, and a piston blocking the movable block, the wedge and the piston cooperating via two inclined planes.

Il est décrit ci-après, à titre d'exemple et en référence à la figure annexée, une butée de réaction selon l'invention. There is described below, by way of example and with reference to the appended figure, a reaction stop according to the invention.

Cette figure montre une butée 10 comportant un corps 11 muni de deux alésages 12, 13 cylindriques et orthogonaux entre eux. This figure shows a stop 10 comprising a body 11 provided with two cylindrical bores 12, 13 orthogonal to each other.

L'alésage 12 reçoit une cale 14 qui sert d'appui à une pièce à usiner 1. Cette cale est poussée à l'extérieur du corps 11 par un ressort 17, en appui sur une plaque 19, cette plaque étant rapportée sur le corps 11 et maintenue par des vis 23. The bore 12 receives a shim 14 which serves as a support for a workpiece 1. This shim is pushed outside the body 11 by a spring 17, bearing on a plate 19, this plate being attached to the body 11 and held by screws 23.

La cale 14 est mobile seulement en translation, un doigt (non représenté) empêchant sa rotation. The wedge 14 is movable only in translation, a finger (not shown) preventing its rotation.

L'alésage 13 reçoit un piston 15 mobile en translation, un doigt (non représenté) empêchant sa rotation. The bore 13 receives a piston 15 movable in translation, a finger (not shown) preventing its rotation.

Ce piston 15 est poussé contre la cale 14 par l'intermédiaire d'une vis 16. This piston 15 is pushed against the shim 14 by means of a screw 16.

La cale 14 compor e un plan incliné 20 et le piston 15 comporte un plan incliné conjugué 21. The wedge 14 has an inclined plane 20 and the piston 15 has a conjugate inclined plane 21.

Une telle butée de réaction est tout d'abord installée sur un poste d'usinage et, pour chaque pièce 1 à usiner, la butée de réaction est utilisée de la manière suivante
Avant la mise en place de la pièce 1, la cale 14 est montée au maximum sous l'action du ressort 17.Such a reaction stop is first installed on a machining station and, for each piece 1 to be machined, the reaction stop is used in the following manner
Before the part 1 is put in place, the shim 14 is mounted to the maximum under the action of the spring 17.

On desserre la vis 16 pour libérer le piston 15. Loosen the screw 16 to release the piston 15.

La pièce 1 est mise en place, ce qui a pour effet de descendre la cale 14, cette cale 14 restant en contact avec la pièce 1 sous l'action du ressort 17. Grâce au sens d'inclinaison des pentes, la descente de la cale 14 peut provoquer le déplacement du piston 15 si la pièce 1 est plus épaisse que la précédente. The part 1 is put in place, which has the effect of lowering the wedge 14, this wedge 14 remaining in contact with the part 1 under the action of the spring 17. Thanks to the direction of inclination of the slopes, the descent of the wedge 14 can cause displacement of the piston 15 if the part 1 is thicker than the previous one.

Mais que le piston 15 soit déplacé ou non, il suffit, dès que la pièce 1 est en place, de visser la vis 16 pour, soit maintenir le piston 15 au contact de la cale 14 s'il a été déplacé, soit le pousser sur la cale 14 s'il n'a pas été déplacé. Le piston 15 empêche alors tout mouvement de descente de la cale, afin d'assurer un appui stable à la pièce 1. La butée de réaction est alors verrouillée dans une position liée à celle de la pièce 1.But whether the piston 15 is moved or not, it suffices, as soon as the part 1 is in place, to screw the screw 16 to either maintain the piston 15 in contact with the shim 14 if it has been moved, or push it on hold 14 if it has not been moved. The piston 15 then prevents any movement of descent of the block, in order to ensure stable support for the part 1. The reaction stop is then locked in a position linked to that of the part 1.

Le sens d'inclinaison des pentes empêche le piston 15 de modifier la position verticale de la cale 14. Ainsi, même si la vis est bloquée exagérément, il n'y a aucune réaction axiale surjala cale 14, donc aucun risque de modification de la position de la pièce 1. The inclination direction of the slopes prevents the piston 15 from modifying the vertical position of the wedge 14. Thus, even if the screw is tightened excessively, there is no axial reaction on the wedge wedge 14, therefore no risk of modification of the workpiece position 1.

Ce sens d'inclinaison a aussi pour effet de donner la plus grande course à la cale 14, ce qui augmente la capacité d'absorption des variations géométriques de la butée de réaction, tout en diminuant son encombrement.  This inclination direction also has the effect of giving the greatest stroke to the shim 14, which increases the capacity for absorbing the geometric variations of the reaction stop, while reducing its size.
