851,034. Chucks. INTEGRAL Ltd. July 1, 1959, No. 22628/59. Addition to 821,969. Class 83 (3). In a modification of the invention according to the parent Specification, the diaphragmchuck has jaws which grip a workpiece internally. The chuck comprises a plate 10 having a work-holding diaphragm 12 carrying internally-gripping jaws 13, and a second diaphragm 20. The diaphragms are secured together by screws 22, and the second diaphragm is distorted by the compression of liquid in the spaces 21, 26, 28, by a piston 25, thus moving the jaws 13 inwardly and allowing the work 17 to be placed over them. Release of the liquidpressure then allows the jaws to grip the work. The jaws are adjustable radially on slides 14. |
