is opened, and the clamp claw 3 is inserted into the drive chamber 2 so as to be able to move back and forth, and the action point 6 is placed at the lower front end of the clamp claw 3, and the fulcrum part 7 and the force point part 16 are placed at the other two locations. An extrusion spring 10 supported on the clamper main body 1 is provided so that the clamp claw 3 can be switched between a retraction position Y in which the action point portion 6 is retracted from the front surface 2a of the drive chamber 2 and an advance position X in which it is advanced. Press the clamp claw 3 forward to push the clamp claw 3 to the advanced position
A wedge-shaped space 18 is formed between the force point part 16 of the clamp claw 3 and the reaction force support part 17 of the wall of the drive chamber 2 facing thereto, This wedge-shaped space 1
A wedge-shaped fastener 15 is inserted into the piston rod 14 of a fluid pressure cylinder H attached to the clamper body 1 so that it can move forward and backward.
When the wedge-shaped fastener 15 is connected to the , and the wedge-shaped fastener 15 is pushed into the wedge-shaped space 18 by the extension force of the fluid pressure cylinder H, the clamp claw 3 at the advanced position X is pivoted to act as a clamp. Point part 6 is changed from unclamping posture A to clamping posture B
In the state in which the wedge-shaped fastener 15 is pushed down and swung, and the wedge-shaped fastener 15 is retreated from the wedge-shaped space 18 by the contraction force of the fluid pressure cylinder H,
The clamp claw 3 is moved back and forth from the advanced position X by releasing the clamp drive of the clamp claw 3 and pulling the retraction locking part 22 provided on the clamp claw 3 backward with the retraction part 21 attached to the fluid pressure cylinder H. A clamper for a processing machine, characterized in that it is configured to move into and out of position Y. 2-Utility Model Registration Scope of Claims In the clamper for the processing machine described in item 1, the wedge-shaped fastener 15 is pushed into the wedge-shaped space 18 by a clamp holding spring 23 mounted on the piston rod 14 of the fluid pressure cylinder H. thing. 3 In the clamper for the processing machine described in claim 1 or 2 of the utility model registration claim, the return spring 24 attached to the clamp jaw 3 moves the clamp jaw 3 to the unclamping position A side with respect to the clamper body 1. Oscillating energized. 4. In the clamper for a processing machine described in claim 1, 2, or 3 of the utility model registration claim, the fluid pressure cylinder H is formed by a hydraulic cylinder, and the piston is inserted into the insertion hole 26 of the annular floating piston 25. The base end of the rod 14 is slidably inserted in an oil-tight manner, and an unclamp oil chamber 20 and a clamp oil chamber 19 are provided before and after the floating piston 25, respectively. When the passive part 27 is fixedly installed and pressure oil is pressurized into the unclamp oil chamber 20, the floating piston 25 moves to the piston passive part 27.
When the piston rod 14 is brought into contact with the clamp oil chamber 19 and pressurized oil is pressurized into the clamp oil chamber 19, the piston rod 14 is moved in and out.
The floating piston 25 does not transmit force to the piston rod 14 due to the pressure oil (moves freely toward the unclamp oil chamber 20 side, and the piston rod 14 receives pressure with an area equal to its cross-sectional area and is driven forward). 5. In the clamper for a processing machine described in any one of the claims 1 to 4 of the claims for utility model registration,
The inner end of a limit switch operating rod 31 is fixed to the clamp claw 3, and the operating rod 31 is attached to the side wall 1b of the clamper body 1.
A limit switch actuator 32 is attached to the outer end of an actuating rod 31 that extends to the outside from an opening 30 formed at the side.
