Abstract

The turntable consists of a rotatable disc with a number of equally spaced radial bolts (2) around its periphery. In addition the disc is provided with indexing devices (3,4) at two different radii. These devices co-operate with a radially guided adjustable stop (7). The radial bolts (2) co-operate with a single radially adjustable socket (8). Reverse rotation of the turntable is prevented by projections (5) which engage a spring (6). Alternatively a free-wheel may be fitted.

Description

L'invention concerne un plateau tournant pour machine de montage ou d'usinage. The invention relates to a turntable for assembly or machining machine.

Les plateaux tournants utilisés dans les machines ou les chaînes de montage ou d'usinage sont en général lourds, avec des dispositifs d'indexage pneumatiques ou électriques qui sont compliqués et onéreux. En outre, ils nécessitent des sécurités complexes pour interdire l'accès pendant la rotation. The turntables used in machines or assembly or machining lines are generally heavy, with pneumatic or electric indexing devices which are complicated and expensive. In addition, they require complex security measures to prevent access during rotation.

La présente invention a pour but d'obtenir un nouveau plateau tournant extrêmement léger et simple, avec un système d'indexage sûr et peu onéreux, et qui ne nécessite pratiquement aucun dispositif de sécurité. Le plateau selon l'invention se prête particulièrement bien à un entraînement manuel. The object of the present invention is to obtain a new extremely light and simple turntable, with a safe and inexpensive indexing system, and which requires practically no safety device. The tray according to the invention lends itself particularly well to manual training.

A cet effet, l'invention a pour objet un plateau tournant pour machine de montage ou d'usinage, caractérisé par le fait qu'il comprend un disque p#ivotant, ledit disque comportant, fixes sur chacun d'une pluralité de rayons espacés angulairement, un pêne de verrouillage et au moins un index fixe, les index sur deux rayons successifs étant sur des circonférences différentes, le plateau comprenant en outre une butée fixe en rotation et coulissant radialement lors de la rotation du disque pour venir coopérer avec un index d'un rayon, un verrou coulissant radialement étant logé à la péri périe dudit disque et étant commandé pour coopérer, à chaque pas de rotation du disque, avec le pêne de verrouillage venant en regard radialement. To this end, the subject of the invention is a turntable for an assembly or machining machine, characterized in that it comprises a p # ivotating disc, said disc comprising, fixed on each of a plurality of spaced spokes angularly, a locking bolt and at least one fixed index, the indexes on two successive spokes being on different circumferences, the plate further comprising a fixed stop in rotation and sliding radially during the rotation of the disc to cooperate with an index of a radius, a radially sliding bolt being housed at the periphery of said disc and being controlled to cooperate, at each pitch of rotation of the disc, with the locking bolt coming opposite radially.

L'invention sera bien comprise à la lecture de la description suivante faite en se référant au dessin annexé dans lequel
- la figure 1 est une vue schématique de dessous en plan d'un plateau tournant selon un exemple de réalisation de l'invention, en position de verrouillage;
- la figure 2 est une vue de dessous en plan du plateau de la figure 1, le disque étant en cours de rotation; et
- la figure 3 est analogue à la figure 1, le disque ayant tourné d'un pas et le verrou étant en cours de verrouillag-e.
The invention will be clearly understood on reading the following description made with reference to the accompanying drawing in which
- Figure 1 is a schematic bottom view in plan of a turntable according to an exemplary embodiment of the invention, in the locked position;
- Figure 2 is a bottom plan view of the tray of Figure 1, the disc being rotated; and
- Figure 3 is similar to Figure 1, the disc having rotated a step and the lock being locked-e.

Le plateau tournant, dans l'exemple de réalisation décrit, comprend un disque pivotant 1 entrainé manuellement dans le sens inverse des aiguilles d'une montre. Le disque 1 porte à sa partie supérieure des supports de pièces (non Tepré- sentés). The turntable, in the example of embodiment described, comprises a pivoting disc 1 driven manually in an anticlockwise direction. The disc 1 carries at its upper part part supports (not shown).

Sur sa face inférieure, le disque 1 porte, sur chacun de six rayons régulièrement répartis angulairement, un pêne de verrouillage 2 adjacent à la périphérie du disque. On its underside, the disc 1 carries, on each of six spokes regularly distributed angularly, a locking bolt 2 adjacent to the periphery of the disc.

En outre, chaque rayon comporte, alternativement, un index intérieur 3 ou un index extérieur 4. Sur une circonférence de plus petit diamètre, un bossage 5 coopère avec un ressort fixe 6 pour interdire le retour du disque 1 en sens inverse. Ce dispositif anti-retour pourrait bien entendu être remplacé par tout dispositif équivalent, par exemple une roue libre.In addition, each spoke has, alternatively, an inner index 3 or an outer index 4. On a circumference of smaller diameter, a boss 5 cooperates with a fixed spring 6 to prevent the return of the disc 1 in the opposite direction. This non-return device could of course be replaced by any equivalent device, for example a freewheel.

Une butée7, fixe en rotation, coulisse radialement, au cours d'un pas de rotation du disque 1, alternativement entre la circonférence des index extérieurs 4 (figure 1) et la circonférence des index intérieurs 3 (figure 3), de manière à venir à chaque pas en regard de l'index de chaque rayon. Le mouvement de translation radiale alternative de la butée 7 peut être commandé par tout moyen convenable, mécanique, électrique, ou pneumatique. Le nombre d'index portés par un rayon peut être supérieur à un, la butée 7 ayant alors un mouvement de translation dans le même sens pour un nombre de pas égal au nombre maximal d'index d'un même rayon. A stop 7, fixed in rotation, slides radially, during a rotation pitch of the disc 1, alternately between the circumference of the external indexes 4 (FIG. 1) and the circumference of the internal indexes 3 (FIG. 3), so as to come at each step opposite the index of each department. The alternative radial translational movement of the stop 7 can be controlled by any suitable means, mechanical, electrical, or pneumatic. The number of indexes carried by a radius can be greater than one, the stop 7 then having a translational movement in the same direction for a number of steps equal to the maximum number of indexes of the same radius.

Enfin, à la périphérie du disque 1, est disposé un verrou 8 coulissant radialement entre une position intérieure de verrouillage (figure 1) par coopération avec un pêne 2 et une position extérieure-de déverrouillage (figures 2 et 3). Finally, at the periphery of the disc 1, is disposed a lock 8 sliding radially between an internal locking position (Figure 1) by cooperation with a bolt 2 and an external-unlocking position (Figures 2 and 3).

Le verrou 8 peut être soumis à l'action d'un moteur électrique (non représenté) commandé par un contact électrique 9 coopérant, à chaque pas, avec l'un des bossages 5.The lock 8 can be subjected to the action of an electric motor (not shown) controlled by an electric contact 9 cooperating, at each step, with one of the bosses 5.

On voit que le dispositif selon l'invention est d'-une construction extrêmement simple et légère. La commande manuelle de rotation peut s'effectuer sans aucun dispositif de sécurité, le débrayage du verrou 8 entraînant automatiquement, par exemple, l'arrêt de l'alimentation des outils. En outre, la disposition du verrou 8 à la périphérie du disque 1 assure un indexage très précis.  It can be seen that the device according to the invention is of an extremely simple and light construction. The manual rotation control can be carried out without any safety device, the disengagement of the lock 8 automatically causing, for example, the power supply to the tools to stop. In addition, the arrangement of the latch 8 at the periphery of the disc 1 ensures very precise indexing.
