ABSTRACT:
The power chuck of the invention features a series of rocker arms which are linked by toggles to the chuck's actuator. The rocker arms are mounted on pivot pins which pivot with respect to carriers within the body of the chuck. The center of gravity of the toggle, rocker arm and jaw mounted on the end of the rocker arm is located inwardly of the pivot pin so to provide increasing clamping force as the rotational speed of the chuck increases. A spring within the carrier provides a pull-back action on the workpiece during clamping.
