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