CA 2676288

A workholding chuck can use actuating members that pivot within a non-split unitary front bearing. The non-split unitary front bearing can include pockets in its central bore that can allow a spherical section of an actuator arm to be inserted into the bearing. The spherical section can include radially recessed areas to facilitate the insertion into the bearing. The jaws can be retained to the actuator arms through the use of a quick-release assembly. The quick-release assembly allows the jaws to easily and quickly be changed to allow the chuck to grasp different workpieces.

L'invention concerne un dispositif de serrage porte-pièce pouvant utiliser des éléments de commande qui pivotent dans un roulement avant monobloc non séparé. Ce roulement avant monobloc non séparé comprend des poches au niveau de son orifice central, permettant d'insérer une section sphérique d'un bras de commande dans le roulement. Cette section sphérique peut comprendre des zones à espaces radiaux facilitant l'insertion dans le roulement. Les mâchoires peuvent être retenues par les bras de commande à l'aide d'un ensemble à ouverture rapide. Cet ensemble à ouverture rapide permet de remplacer facilement et rapidement les mâchoires et de saisir des pièces différentes à l'aide du dispositif de serrage.
