Abstract
A workpiece gripper has a housing part on which is arranged a gripper element actuated by external force for gripping workpieces. Also provided is a joining part, for attaching the workpiece gripper to a tool holder, that can be transferred by means of a tool changing device between a magazine position on a machine tool and a working position on a receptacle in a spindle. Provided on the housing part is a connecting element that, when a tool holder is present in the receptacle, is in engagement with a joining element, to deliver energy for actuation of the gripper element, in such a way that the housing part is held nonrotatably with respect to the spindle head. An adapter is provided which is rotatably mounted on the housing part and to which the gripper element can be attached.
