[0028] Embodiment 2:
[0029] Please refer to Figure 1 - Figure 5 As shown in the figure, on the basis of Embodiment 1, the present utility model provides a technical solution: A fixing member 10 is fixedly connected to the outer wall of the clamping seat 801. Fixing plates 11 are fixedly connected to the front and rear side walls of the fixing member 10. An auxiliary clamping member 9 is fixedly connected to one end of the fixing plate 11 away from the fixing member 10;
[0030] The auxiliary clamping member 9 includes a C-shaped plate 901. An adjusting bolt 902 is threadedly connected to the inner wall of the C-shaped plate 901. The bottom end of the adjusting bolt 902 is rotatably connected to a clamping block 903. Limiting grooves 7 are symmetrically formed on the positioning disk 1. The C-shaped plate 901 is slidably connected to the inner wall of the limiting groove 7.

[0032] Working principle: During use, place the cylinder end cover at the center position of the positioning disk 1, and then start the motor 3 to drive the bidirectional screw 6 to rotate. Under the condition of being limited by the sliding groove 5, the moving blocks 12 at both ends of the bidirectional screw 6 are driven to approach each other. Then, the fixture 8 above the moving block 12 clamps the cylinder end cover. During the clamping process, first start the cylinder to push the suction cup 803 out of the circular groove 802. Driven by the bidirectional screw 6, the fixtures 8 at both ends of it approach each other.

And before abutting against the clamping seat 801, the side wall of the cylinder end cover is first attracted to the inner surface of the suction cup 803, and then start the air pump 15 to pump out the air inside the suction cup 803, enhancing the suction force of the suction cup 803, avoiding the position deviation due to the force during clamping, and improving the clamping stability of the fixture 8 for the cylinder end cover. When the fixture 8 moves, it synchronously drives the auxiliary clamping member 9 to move. After the cylinder end cover is horizontally clamped by the fixture 8, the adjusting bolt 902 is rotated to drive the clamping block 903 to move downward along the C-shaped plate 901 and clamp on the upper surface of the cylinder end cover, thereby longitudinally clamping the cylinder end cover and fully improving the clamping stability of the cylinder end cover. After the processing is completed, start the motor 3 to drive the bidirectional screw 6 to rotate in the reverse direction, and drive the moving blocks 12 at both ends of the bidirectional screw 6 to move away from each other, then the processed cylinder end cover can be removed.
