Abstract

PURPOSE:To provide an air-driven type work chuck which eliminates the reduction in gripping force resulting from the centrifugal force, by providing a conventional wedge type 3-jaw work chuck with a balancing weight receiving base and balancing weights. CONSTITUTION:Three jaw receiving bases 2, three weight receiving bases 3, and a gradient sleeve 7 are incorporated into a chuck main body 1 worked for use for the 6 jaw chuck, and work-chucking soft jaws are mounted on the jaw receiving bases 2 while, on the other hand, balanced balancing weights 6 are incorporated into the weight receiving bases 3.

If it is counteracted by the force exerted, the reduction of the grasping force due to the centrifugal force will disappear.
