MULTI-JAW CHUCK

摘要

A chuck having a plurality of jaw carrying rods slidably arranged within bores inclined relative to the chuck axis. The rods may be axially shifted in opposite directions to thereby increase and decrease the diameter of the circle defined by the jaws for gripping and releasing the peripheral surface of a workpiece. The rods are insertable and removable from the front of the chuck and after insertion are operatively connected to an actuator slide within the chuck by rotary indexing of the rods within their respective bores.
