Abstract
1331743 Chucks ALFRED HERBERT Ltd 5 Oct 1970 [15 Oct 1969] 50583/69 Heading B3B A work-holding device comprises a body 10, locating means on the body for locating the body co-axially with a machine-tool spindle, coupling means on the body for engagement with means on the spindle for urging the locating means into interengagement with complementary locating means on the spindle, and means rotatably mounted on the body and drivingly connected with the coupling means for actuating the coupling means. The locating means comprises a ring 23 formed with gear teeth 24 which form an internal bevel gear with a re-entrant pitch cone. The teeth 24 are arranged to engage complementary locating means in the form of a bevel gear fixed coaxially on the spindle 31 of a machine-tool. The coupling means is formed by a screwthreaded portion 25 rotatably engaged on ring 23. The portion 25 has gear teeth 26 meshing with the teeth of three spur gears 27. Each of the latter has a recess 28 for reception of a tool 33 for rotating the spur gears and hence the portion 25. During such rotation, the portion 25 cooperates with a screw-threaded portion 32 on the spindle 31 whereby the locating means can be drawn into interengagement. Thd chuck has work-gripping jaws 29 (Fig. 2) whose radial positions are adjustable relative to respective slide members 12; each of the latter has a Tee-slot 13 in which a bolt 30 is positioned. Complementary serrations 14 on the slide members and jaws secure the latter to the slide members to prevent slippage. Opening and closing of the jaws is by action of a rotary disc 17 formed with a cam portion 18 which runs in an arcuate recess 16 in each slide member 12. The disc 17 is rotatable by any one of three spur gears 21 each of which has a recess 22 for reception of tool 33. Tool 33 may be part of the machine-tool or may be a separate item; it may be manually or automatically rotated.
