ABSTRACT:
A quick-change chuck includes a power-assist clamp feature for use in a machine tool having a powered draw bar. The chuck body includes inner and outer faces with a bore formed therethrough. A tapered polygon alignment pin extends inwardly from the inner face to center the chuck on a longitudinal axis of the machine tool. An axially-movable member is supported by the body for reciprocation along the longitudinal axis, and jaws which move radially as the axially movable member is reciprocated, are connected to the movable member for receiving and clamping a workpiece. The jaws are normally spring-biased to a preload or clamped position. A clamping stud is also connected to the movable member for receiving the draw bar gripping fingers. An initial stroke of the powered draw bar pulls the stud and registers the chuck onto the machine tool, and further stroke in the same direction displaces the clamping stud and movable member to provide the power-assist clamping to the workpiece.
