Chuck with partially spherical jaw support

摘要

The ball studs (4) are mounted on a chuck plate (3) which is axially displaceable relative to the chuck body (2) against spring force. A switch part is adjustable between a locking position which blocks the spring path of the chuck plate, and a draw-down position which releases the spring path. The chuck plate is attached to guide columns guided in sockets of the chuck body. The switch part can be formed by a cam ring (24) mounted rotatable on the chuck body and designed to interact with the free ends of the guide columns.
