摘要： An apparatus for rapidly changing the top jaws of a power-operated chuck having several jaws which are movably guided in a radial direction in a chuck body. Each chuck jaw is formed by a base jaw, and by a top jaw which is exchangeably mounted on the base jaw. After an arresting mechanism has been released, each top jaw can be removed from its base jaw by a relative movement with respect to the latter. The exchange of the top jaws is effected with the aid of a changing apparatus which can be converted from a rest position into a changing position in front of the chuck. The changing apparatus is provided with guide rails which are adapted to correspond with guide surfaces of the base jaws. At least one top jaw is supported on these guide rails, and can be exchanged for the top jaw presently on the base jaw by being displaced by a pusher, which is provided with engaging elements. In order to avoid expensive drive mechanisms within the changing apparatus, the pushers are driven by a movement which is introduced from the outside into the changing apparatus, with this movement being derived from a movement of a tool, a tool support, or some other driven component of the machine tool or of a workpiece grabbing device associated with this machine tool.
