Abstract

1,263,474. Chucks and mandrels. MOLINS MACHINE CO. Ltd. 24 Sept., 1969 [25 June, 1968], No. 30246/68. Heading B3B. A workpiece 34 is held to a work-table by means of a chuck or device 10 comprising a base 11 which is attached to the work-table, a bush 15 which is slotted to produce resilient fingers 17, and a toggle mechanism 21, 22 operated by a screw 32. When the toggle mechanism is pushed to its nearly straight position a ball 24 is pushed into a conical recess 19 to separate gripping parts 18 of the fingers to expand and grip inside a hole 35 in the workpiece. Each of the parts 21, 22 includes a groove 31 to pivot about a pin 31. A further screw 33 acts as a stop and is adjusted to prevent the toggle parts 21, 22 passing the maximum extended position. Instead of balls 24, 26 the toggle parts 21, 22 may be suitably shaped and bear on flat surfaces which may include a small cylindrical locating hole. The base 11 is located in a work-table by a spigot 13 and clamped by screws. The spigot 13 may be threaded to screw into a locating hole. The device may be used in an alternative manner by first expanding the gripping parts 18 and inserting a spigot which is resiliently externally gripped when the toggle mechanism is released. Pads may be attached to the workpiece 34 that include spigots for gripping in this way.
