Abstract
In a device for the coupling of attachment chucking jaws (31) to basic jaws (11) which are movably guided in a chuck body (2) of a chuck (1), the basic jaws each have an extension (21), projecting in an axial direction, with a collar (23) projecting inwardly and/or outwardly on each extension. A recess (32) is machined into the attachment chucking jaws (31) which recess is provided with an undercut (33) and with a countersurface interacting with a stop surface of the extension (21). A locking member (41) is inserted into each basic jaw for arresting the attachment chucking jaws (31), which locking member is movable axially and introducible into the attachment chucking jaws. The actuation of the locking members is provided by an axially movable control element (42) which is automatically connected mechanically to the locking members (41) via an intermediate member (43) and/or via a deflection member (44). Due to this design the locking action is readily accomplished and monitored.
