When the present invention works, claw is in expanded position, the automatic charging device of lathe pushes the disk hollow cavity that claw is formed with workpiece, and compressing pusher dish moves backward, make the spring compression produce elastic force, workpiece end face is resisted against and carries out the workpiece location on the positioning disk front end face, and claw clamps entad motion under the driving mechanism effect at chuck subsequently, and the inner surface of inserting is conflicted, and clamping work pieces carries out workpiece processing on the workpiece outer surface; After workpiece machined, claw clamped under the driving mechanism effect at chuck and unclamps workpiece, and the pusher dish moves forward under the spring force effect, and workpiece is released the disk hollow cavity that claw is formed, and finishes subjob processing.
As the further of technique scheme improved and replenish, the present invention also comprises following additional technical feature:
Described claw is provided with the axial step through hole, can pass this step through-hole with screw claw and chuck clamping driving mechanism are fixedlyed connected.
Described claw is provided with radially step through-hole, and described inserting is provided with the radially screw corresponding with described radially step through-hole, passes described step through-hole with screw and is screwed into described screw claw is fixedlyed connected with inserting.
Disk diameter under clamped condition that described claw is formed forms the space between the two greater than described positioning disk diameter, is convenient to chip removal.
Side, described claw both sides is provided with radially half slot, and claw is adjacent two half slots composition through hole when forming disk, as channel of chip removal.
The present invention can reach following beneficial effect: chip removal is smooth and easy, and clamping workpiece is stable, accurate positioning, but the diameter range of processing work is wide, and chuck is provided with automatic blanking mechanism and has improved working (machining) efficiency again.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the present invention includes and comprise with chuck and clamp claw 1, base plate 11, pusher dish 4, the positioning disk 12 that driving mechanism is connected, positioning disk 12 is provided with groove, and the bottom portion of groove axis is provided with through hole; Pusher dish 4 hollows, and be positioned at described groove, coaxial with positioning disk 12; Pusher dish 4 internal chamber wall rear portions are provided with and spacingly are provided with coaxial guide post 5 in the inner chamber by shoulder 14, and guide post 5 outer surface front portions are provided with spacing by shoulder 17, the spacing stroke that match to limit pusher dishes 4 by shoulder 14 and 17; Guide post 5 is provided with axial step through hole 16, passes step through-hole 16 with screw 6 guide post 5 is fixedlyed connected with base plate 11; The rear end face of pusher dish 4 is provided with the cannelure 15 coaxial with the pusher dish, is set with spring 13 in the cannelure 15, and spring 13 front ends are resisted against the bottom of cannelure 15, and the rear end is resisted against on the base plate 11; Claw 1 is fan-shaped and is provided with radially step through-hole 9, and the inner surface front portion is provided with inserts 2, inserts 2 to be provided with the radially screw corresponding with step through-hole 9, passes step through-hole 9 with screw 10 and is screwed into described radially screw claw 12 is fixedlyed connected with inserting; Claw 1 is provided with axial step through hole 8, can pass step through-hole 8 with screw claw and chuck clamping driving mechanism are fixedlyed connected; Three claws 1 are formed the disk of hollow, and the disk of composition is coated at positioning disk 12 and coaxial with positioning disk 12, and disk diameter under clamped condition makes to form the space between the two greater than the diameter of positioning disk 12, is convenient to chip removal; Side, claw 1 both sides is provided with radially half slot 7, and claw 1 is adjacent two half slots composition through hole when forming disk, as channel of chip removal.
