该装置的动作过程为:当工件位置放好后，夹钳头在汽缸的推动下伸出;当工件

The action process of the device is: when the position of the workpiece is put, the clamp head is pushed out by the cylinder; when the workpiece enters the clamp mouth, when the side of the plate contacts the induction block, the induction block moves backward, and the proximity switch receives the signal; The control system receives the signal from the proximity switch, the cylinder enters the oil, the upper jaw presses down, presses the plate, and the cylinder piston is locked. After clamping, the clamp moves with the workpiece driven by the gear and rack, Send to the host. Then after the host machine punches the plate, after the control system receives the command, the cylinder is relieved of pressure, the piston rod rises under the action of the cylinder spring, and the chuck returns to the initial position under the action of the return spring. At the same time, locking the cylinder and pulling the cylinder back to the original position, the whole action is over.

The action process of the device is: when the workpiece position is put in place, the clamp head is extended under the push of the cylinder, when the workpiece enters the clamp mouth, the side of the plate comes into contact with the sensing block, the sensor block back, the proximity switch gets the signal; Then when the host to the plate punch processing, the control system is ordered, the cylinder is unpressurized, the piston rod rises under the action of the cylinder spring, the chuck returns to the initial position under the action of the reset spring. At the same time lock the cylinder pull steam the cylinder back to its original position, and the entire action is over.

The action process of the device is as follows: when the workpiece position is put in place, the clamp head extends under the push of the cylinder; when the workpiece enters the jaw, when the side of the plate contacts the sensing block, the sensing block moves back, and the proximity switch gets the signal; the control system receives the signal of the proximity switch, when the oil cylinder enters, the upper jaw presses down, and presses the plate, and the cylinder piston locks; After clamping, the clamp carries the workpiece forward under the drive of gear and rack and sends it to the main engine. Then when the master machine punches the plate and the control system gets the command, the cylinder unloads, the piston rod rises under the action of the cylinder spring, and the collet returns to the initial position under the action of the return spring. At the same time, lock the cylinder and pull the cylinder back to the original position, so that the whole action is over.
