Patent ID: 7913584

Claim:
A support arm for a clamping and/or centering element of a gripper frame for holding three-dimensional components, in which an adjustment mechanism is integrated, with at least one ball that can pivot and/or a cylindrical pin that can slide and rotate, in either case held in a clamping and release unit, wherein the clamping and release unit encompasses the at least one ball and/or the cylindrical pin with clamping jaws that can be radially clamped, wherein a radially directed compression force can be applied to the clamping jaws by a ring-shaped hydraulic force generator that is arranged about the clamping jaws, the clamping jaws are configured as shells engaging on opposing halves of the at least one ball or of the cylindrical pin and in a region of mutually opposing vertices of the at least one ball or cylindrical pin, whose separation distance can be set by a means of adjustment, wherein hydraulic pressure for the ring-shaped hydraulic force generator is applied by a pressure generator integrated in the support arm.
