The output end of the second motor 55 is fixedly connected with a clamping cylinder 56. The second motor 55 drives the clamping cylinder 56 to rotate within a certain angle. Below the clamping cylinder 56, there is a clamping claw 57. The clamping claw 57 moves driven by compressed gas to clamp and fix the metal plate. Inside the positioning disc 2, there are multiple suction pipes 61 communicating. The suction pipes 61 are connected with a vacuum pump 6 below the positioning platform 1.

[0026] like Figure 6As shown in the figure, the lateral movement mechanism 4 includes a lateral movement frame 42. The lateral movement frame 42 is sleeved outside the moving cross beam 13.

[0027] A through hole matching the chute inside the fixed disk 21 is provided inside the positioning platform 1. The air suction pipe 61 passes through the through hole and is communicated with the bottom of the sucker column 24.

[0028] The principle of the present utility model is as follows: When using this device, start the driving motor 7 to drive the rotating disk 22 to rotate. The through hole on the rotating disk 22 presses the sucker column 24, so that the sucker column 24 moves along the chute, and the adsorption range of the sucker 26 is adjusted to be equivalent to the size of the adsorption surface of the plate to be welded. Place the special-shaped metal plate to be welded on the sucker 26, start the vacuum pump 6 to generate negative pressure to adsorb the metal plate on the sucker 26 for fixation. Then place another metal plate in the clamping claws 57, start the clamping cylinder 56 to make the clamping claws 57 clamp to fix the metal plate.
