Abstract

The invention relates to a quick fix device for a tool or component holder. The device according to the invention is characterised in that it comprises a tie bar 8, 9 subjected to a high load 12 and a pin 4 with eccentric movement provided with a disengagement flat 10. Application to thrust cylinders.

Description

DISPOSITIF DE FIXATION RAPIDE
L'invention concerne un dispositif de fixation rapide d'outil ou de porte-pièce permettant un changement rapide et un repositionnement sans reglage autorisant une grande souplesse et une rapidité bleue d'adaptation.QUICK FIXING DEVICE
The invention relates to a quick attachment device for a tool or workpiece carrier allowing rapid change and repositioning without adjustment, allowing great flexibility and rapid blue adaptation.

le dispositif de fixation selon l'invention est caractérisé par le fait qu'il comprend un tirant soumis à une charge élevée et une goupille a mouvement excentrique munie d'un méplat de dégagement. De préférence, un second méplat decalé angulairement par rapport au méplat de dégagement assure une position stable de fixation. La suppression de la charge sur le mécanisme ou l'outil permet un démontage aise par extraction de la goupille, le remontage se faisant par l'opération inverse.the fixing device according to the invention is characterized in that it comprises a tie rod subjected to a high load and a pin with eccentric movement provided with a clearance flat. Preferably, a second flat angularly offset relative to the clearing flat ensures a stable fixing position. The removal of the load on the mechanism or tool allows easy disassembly by extraction of the pin, reassembly being done by the reverse operation.

L'invention sera bien comprise à la lecture de la description suivante faite en se référant au dessin annexé dont la figure unique est une vue en coupe axiale, partiellement en élévation,d'une partie d'un vérin muni d'un dispositif de fixation rapide selon l'invention.The invention will be clearly understood on reading the following description made with reference to the accompanying drawing, the single figure of which is a view in axial section, partially in elevation, of a part of an actuator provided with a fixing device. fast according to the invention.

le vérin comporte une tige 1 coulissant dans une bague de guidage 2 soli daire d'un bâti 3. L'outil monté sur la tige 1 est muni d'une goupille transversale 4 dont la pointe 5 coulisse dans une rainure 6 du guide 16, afin d'interdire la rotation de la tige 1.the jack comprises a rod 1 sliding in a guide ring 2 attached to a frame 3. The tool mounted on the rod 1 is provided with a transverse pin 4 whose tip 5 slides in a groove 6 of the guide 16, to prevent rotation of the rod 1.

Conformément à I 'invention, la tige 1 comporte un axe interne 8 dont la tête 9 est traversée par la goupille 4. Cette goupille 4 comporte un méplat de de-gagesent 10 et un second méplat 11, plus Ftroit, à 900 du aplat 10, servant au positionnement précis et stable de la goupille 4. L'axe 8- est entouré par un ressort helizoldal 12 en appui sur une bague 13 elle-même arrêtée par une butée 14. L'autre extrémité ---------- de la tige 8 est solidaire de l'autre extrémité du ressort 12. La tête 9 de l'axe 8 est en regard d'une creusure 15 à l'intérieur de la tige 1, qui permet un certain jeu axial de la tige 8, contre l'action du ressort 12.Par ddcompres- sion partielle du ressort 12, on peut ainsi libérer l'axe 4 et changer facilement le mécanisme ou l'outil.In accordance with the invention, the rod 1 has an internal axis 8, the head 9 of which is crossed by the pin 4. This pin 4 has a flat part of de-pledge 10 and a second flat part 11, more narrow, 900 of flat 10 , used for precise and stable positioning of the pin 4. The axis 8- is surrounded by a helizoldal spring 12 bearing on a ring 13 itself stopped by a stop 14. The other end ------- --- of the rod 8 is secured to the other end of the spring 12. The head 9 of the axis 8 is opposite a recess 15 inside the rod 1, which allows a certain axial play of the rod 8, against the action of the spring 12. By partial compression of the spring 12, it is thus possible to release the axis 4 and easily change the mechanism or the tool.

Ce système, qui comporte un tirant fortement chargé ( de l'ordre de 100 kg par exemple) et un axe à mouvement excentrique, peut être utilisé d'une manière générale pour la fixation rapide à positionnement stable de tout outil ou porte-pièce dans une machine, donnant une grande flexibilite- d'adaptation, à différents types de pièces par exemple.This system, which comprises a heavily loaded tie rod (of the order of 100 kg for example) and an axis with eccentric movement, can be used in general for the rapid fixing with stable positioning of any tool or workpiece in a machine, giving great flexibility- adaptation, to different types of parts for example.

Un capteur 17 de type inductif est dispose dans un alésage de la tête de la goupille 4 et coopère avec un palpeur de pièce 19 et 18 dans l'outil. On détecte ainsi la présence ou l'absence de pièce dans l'outil, ainsi qu'éventuellement le positionnement de la pièce, sans disposer de capteur dans l'outil lui-rtert#. On évite ainsi d'avoir à brancher et rdgler le capteur à chaque changement d'outil.An inductive type sensor 17 is placed in a bore in the head of the pin 4 and cooperates with a workpiece probe 19 and 18 in the tool. This detects the presence or absence of a part in the tool, as well as possibly the positioning of the part, without having a sensor in the tool itself-rtert #. This avoids having to connect and adjust the sensor each time the tool is changed.

Le guide 8 porte en outre deux capteurs 7, 7' coopérant avec la pointe 5 de la goupille 4 pour détecter les fins de course du vérin. Les capteurs 7, 7' peuvent être remplaces par des interrupteurs fin de course. The guide 8 also carries two sensors 7, 7 'cooperating with the tip 5 of the pin 4 to detect the limit switches of the jack. The sensors 7, 7 ′ can be replaced by limit switches.

La goupille 4 assure ainsi à elle seule un quadruple rôle: - fixation rapide de l'outil ou du mécanisme.The pin 4 thus alone fulfills a fourfold role: - rapid attachment of the tool or mechanism.

- détection des fins de course du macanisme ou de l'outil. - detection of the limit switches of the mechanism or the tool.

- détection de la présence ou de l'absence, éventuellement du bon position nuent de la pièce.- detection of the presence or absence, possibly of the correct position, of the part.

- anti-rotation du mEcanisme ou de l'outil. - anti-rotation of the mechanism or tool.
