Description
Dispositif de serrage Le présent brevet a pour objet un dispositif de serrage plus spécialement destiné à maintenir une pièce à percer, pendant son perçage, dans une ma chine-outil automatique.
Ce dispositif est caractérisé par le fait qu'il com porte une pince comprenant un organe de serrage en matériau élastiquement déformable présentant d'une part une cavité dans laquelle la pièce à tenir est serrée élastiquement par les parois latérales de cette cavité et d'autre part un rebord entourant cette ca vité, et des moyens susceptibles d'agir sur ce rebord de manière à agrandir, par déformation élastique, les dimensions de la cavité pour permettre la mise en place et le retrait de la pièce.
Le dessin annexé représente, à titre d'exemple, une forme d'exécution du dispositif qui fait l'objet de l'invention.
La fig. 1 en est une vue en coupe axiale, une pièce étant serrée dans la pince ; la fig. 2 est une vue semblable montrant la pince ouverte.
Le dispositif représenté est formé d'une pince 10 et d'une lunette 11 destinée à commander l'ouverture de cette pince.
La pince 10 comprend une tige verticale 12 pré sentant à son extrémité supérieure un tronçon 13, de diamètre réduit, sur lequel est chassé un man chon en caoutchouc 14 muni d'un rebord 15. Le corps 16 de ce manchon est serti dans une douille métallique 17 dont le fond prend appui sur l'épaule ment limitant le corps et le tronçon 13 de la tige, et dont la paroi cylindrique empêche toute extension latérale du corps 16. Le bord supérieur de cette douille est enfoncé dans la masse du manchon.
Ce manchon dépasse la face terminale chanfrei née du tronçon 13 de la tige de manière à former une cavité 18 dans laquelle la pièce à percer 19, en l'occurrence une pierre d'horlogerie, est serrée élas- tiquement par la paroi intérieure du manchon.
La portion du manchon 14 en contact avec le tronçon 13 étant comprimée par ce dernier et la pierre 19 étant de diamètre sensiblement égal à celui de ce tronçon, il en résulte que la paroi latérale de la cavité 18 exerce sur la pierre 19 non seulement une action radiale de serrage mais encore une action axiale qui l'applique contre la face chanfreinée du tronçon 13, et lui assigne une position parfaitement bien définie.
L'ouverture de la pince est commandée par la lunette 11 qui est alors disposée concentriquement à la pince 10, au-dessus de celle-ci. Son diamètre extérieur correspond sensiblement à celui du rebord 15. Des moyens non représentés permettent de dé placer verticalement cette lunette de manière à l'ap pliquer contre le bord du rebord 15 et à déformer élastiquement le manchon 14 de la façon illustrée à la fig. 2.
Cette déformation, qui n'affecte que la partie supérieure du manchon laquelle pivote sur le bord supérieur de la douille 17, donne à la cavité une forme évasée vers le haut permettant la mise en place de la _pièce et son retrait.
Si .la pince est destinée à une machine à percer du type de celle décrite dans le brevet susmentionné, on ménagera un dégagement dans la face chanfreinée de la tige, servant de siège à la pièce à percer, pour le passage du foret.
Clamping device The present patent relates to a clamping device more specifically intended to hold a part to be drilled, during its drilling, in an automatic machine tool.
This device is characterized by the fact that it comprises a clamp comprising a clamping member made of elastically deformable material having on the one hand a cavity in which the part to be held is elastically clamped by the side walls of this cavity and on the other share a rim surrounding this cavity, and means capable of acting on this rim so as to enlarge, by elastic deformation, the dimensions of the cavity to allow the installation and removal of the part.
The appended drawing represents, by way of example, an embodiment of the device which is the subject of the invention.
Fig. 1 is a view in axial section, one part being clamped in the clamp; fig. 2 is a similar view showing the clamp open.
The device shown is formed by a clamp 10 and a bezel 11 intended to control the opening of this clamp.
The clamp 10 comprises a vertical rod 12 having at its upper end a section 13, of reduced diameter, on which is driven a rubber sleeve 14 provided with a rim 15. The body 16 of this sleeve is crimped in a sleeve. metal 17 whose bottom rests on the shoulder limiting the body and the section 13 of the rod, and whose cylindrical wall prevents any lateral extension of the body 16. The upper edge of this sleeve is embedded in the mass of the sleeve.
This sleeve protrudes from the chamfered end face of the section 13 of the rod so as to form a cavity 18 in which the part to be drilled 19, in this case a timepiece, is clamped elastically by the inner wall of the sleeve. .
The portion of the sleeve 14 in contact with the section 13 being compressed by the latter and the stone 19 being of diameter substantially equal to that of this section, it follows that the side wall of the cavity 18 exerts on the stone 19 not only a radial clamping action but also an axial action which applies it against the chamfered face of the section 13, and assigns it a perfectly well defined position.
The opening of the clamp is controlled by the bezel 11 which is then arranged concentrically with the clamp 10, above the latter. Its outer diameter corresponds substantially to that of the rim 15. Means, not shown, make it possible to move this bezel vertically so as to apply it against the edge of the rim 15 and to elastically deform the sleeve 14 as illustrated in FIG. 2.
This deformation, which only affects the upper part of the sleeve which pivots on the upper edge of the sleeve 17, gives the cavity a flared upward shape allowing the installation of the piece and its removal.
If the clamp is intended for a drilling machine of the type described in the above-mentioned patent, a clearance will be provided in the chamfered face of the rod, serving as a seat for the part to be drilled, for the passage of the drill.
