Abstract

A gripper for a manipulation installation such as an industrial robot characterized by a gripping arrangement including a gripping element movable into a receiving bore to enable gripping a cylindrical part. In order to compensate for misalignment between the bore and the cylindrical part and for tilting of the part, the cylindrical bore is provided in a slidable member and has a frusto-conical opening facing toward the part to act as a centering bell so that upon engagement of the part with the surface of the frusto-conical opening the slidable member moves to the desired position to allow insertion of the part into the bore. To enable exact positioning of the part after it is grasped by the gripping arrangement and removed from a rack or storage facilities, the gripper includes a centering arrangement to precisely center the movable member in the housing.
