Pull bar is comprised of the frustum of a cone and cylinder, is provided with three connectors at 120 ° at interval at the circumference of pull bar truncated cone, and connector is fixed together by locking nut, pad, pressing plate and pull bar.
Described left fixed body is that through hole, the cylindrical shape of projection are on every side arranged at the bottom, is formed with the disk of shoulder hole centered by the right fixed body.
The profile of described positioning disk is "T"-shaped, is installed in the shoulder hole of right fixed body, and the right side at right fixed body is given prominence in its front portion, is formed centrally through hole in positioning disk, forms the blind hole that stacks workpiece in the right side of positioning disk.
The present invention is specially adapted to the endoporus processing of disk sheet part, and crudy is good, efficient is high, cost is low.

The specific embodiment
Below, in conjunction with the accompanying drawings and embodiments a kind of automatic clamping device of the present invention is elaborated:
As shown in Figure 1, 2, a kind of automatic clamping device comprises left fixed body 1 and the right fixed body 2 that is fixedly connected with left fixed body 1, and left fixed body 1 is formed with the disk of shoulder hole for through hole, the cylindrical shape of projection are on every side arranged at the bottom centered by the right fixed body 2.The profile of positioning disk 3 is approximately "T"-shaped, is installed in the shoulder hole of right fixed body 2, and give prominence in the right side of right fixed body 2 its front portion, is formed centrally through hole in positioning disk 3, forms the blind hole 17 that stacks workpiece in the right side of positioning disk 3.
Form the through hole of 120 ° of three each intervals at the disk of the shoulder hole periphery of right fixed body 2, three support sets 6 are separately fixed in the through hole, round sides at support set 6 has circular hole 7, in circular hole 7, be fixed with straight pin 8, screw rod 5 penetrates support set 6 and stretch out at two ends, external peripheral surface at screw rod 5 is formed with a plurality of helicla flutes 16, and straight pin 8 one ends insert in the circular hole 7, and the other end inserts in the helicla flute 16.
One end of screw rod 5 is fixedly connected with claw 4 by bolt, makes claw 4 be positioned at the place ahead of positioning disk 3, and the other end of screw rod 5 is fixed together with connector 9 by fixed cover 10 and clamp nut 11.
As shown in Figure 3, pull bar 12 is comprised of the frustum of a cone and cylinder, is provided with three connectors 9 at 120 ° at interval at the circumference of pull bar 12 truncated cones, and connector 9 is fixed together by locking nut 13, pad 14, pressing plate 15 and pull bar 12.Pull bar 12 is connected the end that connects and is arranged in the left space " C " that body 1 and right fixed body 2 form of decide with connector, the other end of pull bar 12 passes the left through hole of deciding body 1, also is connected with hydraulic gear.
The angle of claw 4 rotations is relevant with the number of helicla flute 16, and the number of helicla flute 16 is more, and the angle of claw 4 rotations is just larger, and the angle of claw 4 rotations is preferably 45 °.
The course of work of the present invention:
During work, multi-disc disk sheet workpiece 18 is overlayed in the blind hole 17 of positioning disk 3, start hydraulic gear, pull bar 12 drive connectors 9 and screw rod 5 are to left movement.Simultaneously, straight pin 8 moves along helicla flute 16, so that screw rod 5 and claw 4 also rotated in the straight-line while, so that three claws 4 rotate the dead ahead to positioning disk, and gradually near positioning disk 3, until compress the workpiece that is contained on the positioning disk 3, workpiece, can be processed on positioning disk 3 by stable clamping.
After machining, contrary operation takes out workpiece.
The present invention is specially adapted to the endoporus processing of disk sheet part, and crudy is good, efficient is high, cost is low.
