[0028] Among them, an arc groove is formed inside the support plate 2, and an arc plate 11 slidably connected to the arc groove is fixedly connected to the rear side of the connecting plate 4.

[0029] In this embodiment, during the actual use process, when the first motor 3 drives the connecting plate 4 to rotate, the arc plate 11 will rotate in the arc groove at this time, and the arc groove stabilizes and restricts the moving direction of the arc plate 11.

[0030] Among them, a through groove is arranged below the arc groove, and the through groove penetrates through the support plate 2 and extends vertically downward.

[0031] In this embodiment, during actual use, after the laser welding gun 10 welds the workpieces, the generated debris will fall onto the base 1 along the through groove below the arc groove without blocking the arc groove. At the junction of the arc groove and the through groove, the area of the arc plate 11 is larger than that of the through groove, so the arc plate 11 will not conflict with the through groove.

[0032] Among them, the two moving devices 7 include second motors 71 respectively fixedly connected to the inside of the protection box 5 and the outside of the first mounting plate 6. Thread rods 72 respectively rotatably connected to the inside of the protection box 5 and the inside of the first mounting plate 6 are fixedly connected to the outer sides of the output shafts of the two second motors 71. Transmission blocks 73 are in threaded transmission connection with the outer sides of the two thread rods 72.

[0033] In this embodiment, during actual use, the start of the second motor 71 will drive the thread rod 72 to rotate, and the two transmission blocks 73 will move through the thread.

Fixing sleeves 13 respectively slidably connected to the two fixing rods 12 are fixedly connected to the top of the first mounting plate 6 and the top of the second mounting plate 8.

[0037] In this embodiment, during actual use, during the movement of the two mounting plates, the two fixing sleeves 13 will be fixed on the outer sides of the fixing rods 12, and the fixing rods 12 limit the moving directions of the first mounting plate 6 and the second mounting plate 8.

[0038] Working principle:

[0039] When welding a workpiece, the workpiece can be placed and fixed on the top surface of the base 1 through fasteners. When the electric push rod 9 is started, the laser welding gun 10 can move directly downward to weld the workpiece below. When the second motor 71 above is started, the first mounting plate 6 will move back and forth, driving the laser welding gun 10 to move back and forth. When the second motor 71 below is started, the second mounting plate 8 will move left and right, driving the laser welding gun 10 to move left and right. The first motor 3 can also be started to make the connecting plate 4 drive the protective box 5 to rotate at a certain angle to change the orientation of the laser welding gun 10. The rotation angle is less than one week to prevent the wires from getting entangled, so as to weld different positions of the workpiece.
