Arrière plan de l'inventionBackground of the invention

Les biseaux de glaces de montre sont en général formés par une meule qui se déplace tangentiellement selon l'angle du biseau contre le bord de la pièce à tailler. Cette technique est répandue mais est lente à opérer, provoque régulièrement des égrisures (éclats de matière) et nécessite un brossage postérieur.Watch ice wedges are generally formed by a wheel that moves tangentially at the angle of the bevel against the edge of the workpiece. This technique is widespread but is slow to operate, regularly causes grittiness (splinters of matter) and requires subsequent brushing.

Résumé de l'inventionSummary of the invention

Le but de la présente invention est de pallier tout ou partie les inconvénients cités précédemment en proposant un système d'usinage d'un biseau permettant une fabrication plus rapide et qui abaisse le taux de rebut.The object of the present invention is to overcome all or part of the disadvantages mentioned above by proposing a machining system of a bevel for faster manufacturing and which lowers the scrap rate.

Description détaillée des modes de réalisation préférésDetailed Description of the Preferred Embodiments

Comme illustré à la figure 1, l'invention se rapporte à un système d'usinage 1 d'un biseau 32, 34 pour une glace de pièce d'horlogerie discoïdale 31 en matériau dur comme du corindon. Selon l'invention, la pièce 31 peut être notamment destinée à former une glace sphérique de pièce d'horlogerie.As illustrated in figure 1 , the invention relates to a machining system 1 of a bevel 32, 34 for a piece of hardened timepieces 31 made of hard material such as corundum. According to the invention, the piece 31 may be especially intended to form a spherical ice timepiece.

Le système d'usinage 1 comporte un dispositif de meulage 3, un dispositif de fixation 5 de la pièce et un dispositif de commande 7 permettant de gérer les actionneurs du système 1, tous les dispositifs étant montés sur un bâti 2.The machining system 1 comprises a grinding device 3, a fixture 5 of the workpiece and a control device 7 making it possible to manage the actuators of the system 1, all the devices being mounted on a frame 2.

Selon l'invention, le dispositif de meulage 3 comprend des moyens abrasifs 4 qui sont, de manière préférée, mobiles afin d'améliorer l'usinage. Comme visible à la figure 2, les moyens abrasifs 4 sont formés par une bande abrasive 6 montée à rotation sur deux galets 8, 10 et entraînée par un actionneur 12 selon le mouvement A. Comme visible aux figures 1 à 3, le dispositif de meulage 3 comportent une zone 14 restreinte dans laquelle les moyens abrasifs 4 sont accessibles et protégées par des parois verticales afin de limiter les projections de matière et sécuriser les manipulations.According to the invention, the grinding device 3 comprises abrasive means 4 which are preferably movable in order to improve the machining. As visible at figure 2 the abrasive means 4 are formed by an abrasive belt 6 rotatably mounted on two rollers 8, 10 and driven by an actuator 12 according to the movement A. As visible in FIGS. Figures 1 to 3 , the grinding device 3 comprises a restricted zone 14 in which the abrasive means 4 are accessible and protected by vertical walls to limit the projections of material and secure handling.

Selon l'invention, le dispositif de meulage 3 comporte, en outre, sous la zone 14 de contact entre la bande abrasive 6 et la pièce 31 à usiner, des moyens élastiques 9 afin de maintenir le contact entre la bande abrasive 6 et ladite pièce. Ainsi, préférentiellement, les moyens élastiques 9 sont formés par un bloc 11 en élastomère tel que du caoutchouc de plusieurs centimètres d'épaisseur et tapissant tout ou partie de la zone restreinte 14 sous les moyens abrasifs 4.According to the invention, the grinding device 3 further comprises, under the contact zone 14 between the abrasive belt 6 and the workpiece 31 to be machined, resilient means 9 in order to maintain contact between the abrasive belt 6 and said workpiece . Thus, preferably, the elastic means 9 are formed by an elastomer block 11 such as rubber several centimeters thick and lining all or part of the restricted zone 14 under the abrasive means 4.

Selon l'invention, le dispositif de fixation 5 de la pièce 31 comporte un support 13 sur lequel est ajustée la pièce 31 à usiner et qui est solidaire d'un axe de rotation 16 entraîné par un actionneur 18 selon le mouvement B. Selon l'invention, le dispositif de fixation 5 comporte en outre des moyens d'orientation 15 de l'axe de rotation 16 permettant de définir l'angle β, γ du biseau 32, 34 et des moyens de rapprochement 17 du support 13 par rapport aux moyens abrasifs 4 afin d'usiner la pièce 31 sous contrainte.According to the invention, the fixing device 5 of the part 31 comprises a support 13 on which is fitted the workpiece 31 to be machined and which is integral with an axis of rotation 16 driven by an actuator 18 according to the movement B. According to the the invention, the fastening device 5 further comprises means 15 for orienting the axis of rotation 16 making it possible to define the angle β , γ of the bevel 32, 34 and the means of approach 17 of the support 13 with respect to the abrasive means 4 to machine the workpiece 31 under stress.

Préférentiellement selon l'invention, les moyens de rapprochement 17 comportent un chariot vertical 19 permettant de déplacer verticalement selon la direction C, le support 13 par rapport aux moyens abrasifs 4. En effet, il a notamment été trouvé que la combinaison de la contrainte induite par les moyens de rapprochement 17 et la compensation effectuée par les moyens élastiques 9 pour maintenir le contact entre la bande abrasive 6 et la pièce 31 à usiner permettait de biseauter 32, 34 plus rapidement sans que la matière subisse des contraintes excessives entraînant un faible taux de rebut et le retrait d'une étape supplémentaire de brossage du biseau 32, 34.Preferably, according to the invention, the means of approach 17 comprise a vertical carriage 19 making it possible to move vertically in the direction C, the support 13 with respect to the abrasive means 4. In fact, it has been found in particular that the combination of the induced stress by the means of approach 17 and the compensation made by the elastic means 9 to maintain the contact between the abrasive belt 6 and the workpiece 31 to be able to bevel 32, 34 more quickly without the material undergoes excessive stress resulting in a low rate discarding and removing an additional step of brushing the bevel 32, 34.

Les moyens d'orientation 15 comportent, de manière préférée selon l'invention, un ensemble 20 vis-sans-fin - roue dentée destiné à décaler l'inclinaison α de l'axe de rotation 16 du support 13 par rapport aux moyens de rapprochement 17. Ainsi, avantageusement, l'angle du biseau β, γ de la pièce 31 est directement donné par l'inclinaison α de la pièce 31 par rapport aux moyens abrasifs 4.The orientation means 15 comprise, in a preferred manner according to the invention, a set 20 screw-endless - toothed wheel for shifting the inclination α of the axis of rotation 16 of the support 13 relative to the means Thus, advantageously, the angle of the bevel β , γ of the part 31 is directly given by the inclination α of the part 31 with respect to the abrasive means 4.

Enfin, le dispositif de fixation 5 comporte, préférentiellement, un chariot horizontal 21 permettant de déplacer transversalement selon la direction D, le support 13 par rapport aux moyens abrasifs 4. Comme visible aux figures 1 à 3, le chariot horizontal 21 est utilisé comme base pour le dispositif de fixation 5 sur le bâti 2. Ainsi, par le biais d'une équerre 22, le chariot horizontal 21 supporte le chariot vertical 19, lui-même supportant les moyens d'orientation 15 et l'ensemble support 13 - axe de rotation 16 - actionneur 18.Finally, the fixing device 5 comprises, preferably, a horizontal carriage 21 for moving transversely in the direction D, the support 13 with respect to the abrasive means 4. As visible in FIGS. Figures 1 to 3 , the horizontal carriage 21 is used as a base for the fastening device 5 on the frame 2. Thus, by means of a bracket 22, the horizontal carriage 21 supports the vertical carriage 19, itself supporting the orientation means 15 and the support assembly 13 - axis of rotation 16 - actuator 18.

Avantageusement selon l'invention, le chariot horizontal 21 est déplacé par l'intermédiaire d'un ensemble 23 du type bielle - manivelle afin de déplacer le support 13 transversalement selon la direction D par rapport aux moyens abrasifs 4 selon un mouvement de va-et-vient. Comme visible aux figures 1 à 3, l'ensemble 23 du type bielle - manivelle est relié au chariot horizontal 21 au niveau de l'équerre 22.Advantageously according to the invention, the horizontal carriage 21 is moved via an assembly 23 of the connecting rod-crank type in order to move the support 13 transversely in the direction D with respect to the abrasive means 4 in a movement of va-and -Comes. As visible to Figures 1 to 3 , the assembly 23 of the connecting rod - crank type is connected to the horizontal carriage 21 at the bracket 22.

Un exemple de pièce 31 modifiée par le système d'usinage 1 est illustré aux figures 4 et 5. La pièce 31 comporte un corps 33 sensiblement discoïdal dont les bords comportent des biseaux 32, 34 selon des angles prédéfinis β, γ. Comme visible à la figure 5, la pièce 31 est une glace sphérique, c'est-à-dire qu'elle comporte un rayon extérieur 35 et un rayon intérieur 36 dont la différence de cote représente l'épaisseur constante e.An example of a part 31 modified by the machining system 1 is illustrated in FIGS. Figures 4 and 5 . The part 31 comprises a substantially discoidal body 33 whose edges comprise bevels 32, 34 according to predefined angles β , γ . As visible at figure 5 , the piece 31 is a spherical ice, that is to say it has an outer radius 35 and an inner radius 36, the difference in dimension represents the constant thickness e.

Bien entendu, la présente invention ne se limite pas à l'exemple illustré mais est susceptible de diverses variantes et modifications qui apparaîtront à l'homme de l'art. En particulier, la forme de la pièce 31 peut être différente et/ou d'une matière différente du corindon.Of course, the present invention is not limited to the illustrated example but is susceptible of various variations and modifications that will occur to those skilled in the art. In particular, the shape of the piece 31 may be different and / or a different material corundum.
