摘要： A multiple-jaw chuck comprises a housing (2) and a drive cylinder (4) driven parallel to the longitudinal axis (LA) of the housing (2) and driving a plurality of chuck jaws (3) towards and away from the longitudinal axis (LA) of the housing. The chuck includes one or more axially-extending pins (42) for each chuck jaw (3) fixed to the drive cylinder (4) at an acute angle to the longitudinal axis (LA) of the housing. Each chuck jaw (3) includes a bore (37) for each pin (42) and formed at the same acute angle, such that each chuck jaw (3) is driven radially towards and away from the longitudinal axis (LA) of the housing (2) when the drive cylinder (4) is driven parallel to the longitudinal axis (LA). Each chuck jaw (3) includes an inner drive arm (31) coupled to the drive cylinder (4), and an outer workpiece-engaging arm (32), each of the drive arms (31) being of substantially cylindrical configuration and movable in a bore (25) of corresponding cylindrical configuration formed in the housing (2).
