Centering and drilling jig, (event device) being composed of a retractable drill bushing (8) which can be placed under the drill of a drilling machine, a drill to which the drill bushing (8) can serve as a guide, this drill being lowered through the drill bushing to carry out the centering of a work piece to be drilled, characterized concerning the automatic manner to position and retract the drill bushing (8) by means of a pneumatic cylinder (4, 5) which supports the drill bushing and which is controlled by a control device (15, 16) which can be actuated by the feeding lever of a drilling machine.

Description

La présente invention a pour objet un dispositif de centrage et perçage avec canon rétractable.The present invention relates to a centering and drilling device with retractable barrel.

Ce dispositif se caractérise par le fait que le canon de perçage peut être amené sous la mèche pour centrer, et reculé ensuite pour percer, par simple pression du levier de perçage contre une butée munie d'un interrupteur.This device is characterized by the fact that the piercing barrel can be brought under the drill bit to center, and then moved backward to pierce, by simple pressure of the piercing lever against a stop provided with a switch.

Ce dispositif est fixé à la colonne de la perceuse moyennant un collier en deux parties bloqué par quatre vis. Une de ces deux parties du collier est surmontée d'une semelle dans laquelle est usinée une entrée de " T " sur toure sa longueur. Une glissière est fixée sur cette semelle par deux vis prises dans l'entrée de " T ". La glissière est surmontée d'un cylindre. L'axe du piston de ce cylindre est fileté à une de ses extrémités. A cette extrémité, est vissé un plot auquel est fixé une languette par deux vis. Dans cette languette est logé le canon de perçage, celui-ci peut être monté ou descendu, suivant la longueur de la mèche, par la glissière qui est fixée par deux vis sur la semelle.This device is fixed to the drill column by means of a two-part collar locked by four screws. One of these two parts of the collar is surmounted by a sole in which an entry of "T" is machined on its length. A slide is fixed on this sole by two screws taken in the entry of "T". The slide is surmounted by a cylinder. The axis of the piston of this cylinder is threaded at one of its ends. At this end, a stud is screwed to which a tongue is fixed by two screws. In this tab is housed the drilling barrel, it can be raised or lowered, along the length of the drill bit, by the slide which is fixed by two screws on the sole.

Le dessin annexé montre à titre d'exemple, une forme d'exécution du dispositif et l'adaptation à une perceuse selon l'invention.The accompanying drawing shows by way of example, an embodiment of the device and the adaptation to a drill according to the invention.

  • La figure 1 est une vue de l'adaptation du dispositif sur une colonne de perceuse.Figure 1 is a view of the adaptation of the device on a drill column.
  • La figure 2 est une vue de face du dispositif.Figure 2 is a front view of the device.
  • La figure 3 est une vue de la fixation de l'interrupteur de la commande du piston.Figure 3 is a view of the attachment of the piston control switch.

Le collier 1, en deux parties, est fixé à la collone de la perceuse par les quatre vis de fixation 13.The collar 1, in two parts, is fixed to the collar of the drill by the four fixing screws 13.

Une des deux parties est pourvue d'une semelle 2 dans la-. quelle est fraisée une entré de " T " sur toute sa longueur. Une glissière 3 est fixée par les deux vis 12 sur la semelle 2, permettant le réglage de hauteur suivant la longueur des mèches. La glissière 3 est surmontée d'un cylindre 4. L'axe du piston 5 a son extrémité filetée sur laquelle est vissé un plot 9 pour le réglage du centrage. La languette 7 est fixée au plot 9 par les deux vis 17. A l'extrémité de la languette est logé le canon de percage 8. Le plot 9 est guidé par une barre 6 qui glisse dans un coussinet 10, ce qui l'empêche de tourner. L'entrée d'air dans le cylindre 4 se fait par les orifices 11. Le piston est guidé dans le cylindre par guide-billes 18 aux deux extrémités, ce qui donne un déplacement rigide et précis. En faisant monter la broche de la perceuse par le levier de perçage, la bague 14 qui est fixée à la broche vient buter un poussoir 15. Ce poussoir 15 transmet une pression à un interrupteur 16, qui envoie un courant électrique à une électrovanne, celle-ci envoie de l'air comprimé dans le cylindre 4 qui fait avancer le piston et le canon 8 pour le centrage. Une fois la pièce centrée, la broche est montée par le levier de perçage. La bague 14, qui est fixée à la broche, bute de nouveau le poussoir 15.One of the two parts is provided with a sole 2 in the. which is milled an entry of "T" over its entire length. A slide 3 is fixed by the two screws 12 on the sole 2, allowing the height to be adjusted according to the length of the wicks. The slide 3 is surmounted by a cylinder 4. The axis of the piston 5 has its threaded end on which a stud 9 is screwed for adjusting the centering. The tongue 7 is fixed to the stud 9 by the two screws 17. At the end of the tongue is housed the drilling barrel 8. The stud 9 is guided by a bar 6 which slides in a bearing 10, which prevents it to turn. The air enters the cylinder 4 through the orifices 11. The piston is guided in the cylinder by ball guide 18 at the two ends, which gives a rigid and precise movement. By raising the spindle of the drill by the drilling lever, the ring 14 which is fixed to the spindle abuts a pusher 15. This pusher 15 transmits a pressure to a switch 16, which sends an electric current to a solenoid valve, that -this sends compressed air into the cylinder 4 which advances the piston and the barrel 8 for centering. Once the workpiece is centered, the spindle is mounted by the drilling lever. The ring 14, which is fixed to the spindle, again stops the pusher 15.

A cette deuxième pression, l'interrupteur 16 est de nouveau ouvert. L'électrovanne envoie de l'air comprimé à l'opposé du cylindre 4 et fait reculer le piston ainsi que le canon 8, la mèche est libre et le perçage peut s'effectuer librement sans canon.At this second pressure, the switch 16 is again open. The solenoid valve sends compressed air opposite the cylinder 4 and causes the piston as well as the barrel 8 to move back, the drill bit is free and drilling can be carried out freely without the barrel.

L'avantage de ce dispositif consiste en ce que l'on peut percer des pièces correctement, sans difficultés et sans bourrage dans le canon.The advantage of this device is that one can pierce parts correctly, without difficulty and without jamming in the barrel.

Claims (5)

1. Dispositif de centrage et perçage avec canon rétractable caractérisé par le-fait que le canon de perçage peut être avancé sous la mèche. En abaissant la broche de la perceuse, la mèche traverse le canon de perçage et vient percer la pièce qui se tourve sous le canon. Après un perçage d'environ 1 mm. de profondeur, pour faire un centrage dans la pièce à percer, on fait remonter la broche de la perceuse, la mèche sort du canon, celui-ci se rétracte. En abaissant la broche de la perceuse, la mèche vient se planter dans le trou qui a été fait avec le canon de perçage. Le perçage peut alors être exécuté à la profondeur voulue avec une grande précision.1. Centering and drilling device with retractable barrel characterized by the fact that the drilling barrel can be advanced under the drill bit. By lowering the spindle of the drill, the drill bit passes through the drilling barrel and comes to pierce the part which turns under the barrel. After drilling around 1 mm. deep, to make a centering in the part to be drilled, we bring up the spindle of the drill, the drill bit comes out of the barrel, it retracts. By lowering the spindle of the drill, the drill bit is planted in the hole which was made with the drilling barrel. The drilling can then be carried out at the desired depth with great precision. 2.
