Title (EN) AUTOMATIC MULTISPINDLE LATHE
(FR) TOUR AUTOMATIQUE MULTIBROCHE
Abstract:
(EN) Automatic multispindle lathe having a plurality of drive spindles (14). According to the present invention, each of the drive spindles (14) comprises an electric motor (18). Supply units are associated with electric motors with at least one stationary device being supplied by an external voltage source and at least one device rotating in unison therewith. There are also provided units for regulating the position and the rotational speed, which are provided for each drive spindle with an angular rotation sensor for the angular coding in absolute values, comprising an emitter element (32) which synchronously rotates with the drive spindle, as well as a stationary sensor device (34).
(FR) Tour automatique multibroche avec plusieurs broches motrices (14). Conformément à la présente invention, chacune des broches motrices (14) comporte un moteur électrique (18). Aux moteurs électriques sont adjointes des installations d'alimentation avec au moins un dispositif stationnaire alimenté par une source de tension externe et au moins un dispositif tournant de concert avec celui-ci. Sont en outre prévues des installations de régulation de position et de vitesse de rotation qui possèdent par broche motrice un capteur angulaire de rotation pour le codage angulaire en valeur absolue, comportant un élément transmetteur (32) tournant de manière synchrone avec la broche motrice, ainsi qu'un dispositif détecteur stationnaire (34).
