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