Title: Power operated chuck for lathes - in which all three jaws exert the same force on the component being clamped
Inventor: KIRST RUDI
IPC: B23B31/177
Filed: 1974-04-08
Abstract: The chuck jaw blocks have 'T' sectioned guide rails along the bottom edges. These rails are at a slope and engage with T slots in a piston. The piston has an annular groove near its rear end, with which the rim of a bayonet coupling can engage. The bayonet coupling connects the piston to a hydraulic or pneumatic actuator which pulls the piston backwards. As the T section on the jaws are at an angle, the jaws will be pulled inward and forced against the part to be clamped. The piston has radial play in the chuck so that the three jaws can centralise themselves. When the jaws are pulled down and forward eu to their movement in the sloping T slot, the jaws push against a plate in which a centralising cone is mounted. This cone will engage with a centre in the part being clamped.
