Abstract

1,109,109. Tool-clamping. CHARLES CHURCHILL & CO. Ltd. 27 Oct., 1966 [3 Nov., 1965], No. 46566/65. Heading B3B. A machine tool spindle 2 comprises a tapered socket 20 and spring-loaded jaws 5 for engaging an arbor end (6A) and means for positively clamping the jaws. The spindle has splines 23 to engage a driving gear (25) and is fed by a screw 4 rotated by gearing 24. When the spindle 2 is retracted, the end 3 of a tie-bar assembly 10, 11 abuts the screw 4 causing the jaws 5 to move relatively to the spindle so that the jaw-ends lie opposite to recesses 7A. An arbor can then be inserted into the jaws which snap over the end under the action of a spring 8. When the spindle is advanced, the tie bar is released and springs 1 cause the jaws to be clamped about the arbor. The spindle cannot be rotated unless the arbor is clamped.
