The tops of the two sliding blocks 11 are fixed with first cylinders 12, and the two first welding guns 3 are respectively fixed on the telescopic ends of the two first cylinders 12. 12 can change the height of the first welding gun 3, which is convenient for welding pipes of different heights. A bidirectional screw 13 is rotatably provided at the bottom of the workbench 1. The two sliding blocks 11 are respectively threadedly connected to the two threaded sections of the bidirectional screw 13. A first motor 14 is fixedly provided on the workbench 1 and the output end of the first motor 14 is fixedly connected to the end of the bidirectional screw 13. The arrangement of the first motor 14 and the bidirectional screw 13 facilitates the synchronous movement of the two sliding blocks 11. The first welding gun 3 is a plasma welding gun and the welding gun is vertically placed on the telescopic end of the first cylinder 12.

[0026] like Figure 1 As shown, the workbench 1 is provided with a second welding gun 4 for welding the side of the seat bracket, the first welding gun 3 is a plasma welding gun and the welding gun is horizontally placed on the telescopic end of the third cylinder 16, the workbench 1 is fixedly provided with a second cylinder 15, the telescopic end of the second cylinder 15 is fixedly provided with a third cylinder 16, the second welding gun 4 is fixedly provided on the telescopic end of the third cylinder 16, and the setting of the second cylinder 15 can drive the horizontal movement of the second welding gun 4, so that the second welding gun 4 is convenient to move away from or close to the pipe connection, and the setting of the third cylinder 16 can drive the vertical movement of the second welding gun 4, so that the second welding gun 4 can perform vertical welding on the side of the pipe connection.

[0028] Working principle:

[0029] First, the operator places the four pipes of the seat bracket on the mounting block 6 respectively. At this time, the four pipes form a closed rectangle. Then the operator rotates the first screw 7. The rotation of the first screw 7 drives the moving block 8 to move in the slide groove 9. The moving block 8 can clamp the pipe between the moving block 8 and the mounting block 6, thereby forming a frame of the seat bracket.

[0030] After that, the operator starts the first motor 14, and the first motor 14 drives the bidirectional screw 13 to rotate. The rotation of the bidirectional screw 13 drives the two sliding blocks 11 on the two threaded sections to move. The movement of the sliding blocks 11 drives the first welding gun 3 to move. When the first welding gun 3 moves to the pipe where welding is required, the operator starts the first welding gun 3, and the first welding gun 3 can weld the connection between the two adjacent pipes. While the first welding gun 3 is welding, the operator starts the second cylinder 15, and the second cylinder 15 drives the third cylinder 16 to move, thereby driving the second welding gun 3 to move. The connecting gun 4 moves to the place where welding is required on the outer side of the pipe, and the second welding gun 4 can weld the sides of the connection of the two adjacent pipes. When the welding of the first welding gun 3 and the second welding gun 4 is completed, the operator pulls the clamping rod 21 to disengage the clamping rod 21 from the limiting hole 17, and then rotates the placement plate 2. The rotation of the placement plate 2 drives the pipe to move, and rotates the unwelded part of the pipe to the first welding gun 3 and the second welding gun 4, and then clamps the clamping rod 21 with the limiting hole 17, and then welds again through the first welding gun 3 and the second welding gun 4.

[0031] When welding on one side of the pipe is completed, the operator removes the pipe from the mounting block 6 and places the welded portion of the pipe on the clamping assembly, so that the unwelded side of the pipe is opposite to the first welding gun 3 up and down, and then the operator starts the first welding gun 3 and the second welding gun 4 again to weld the pipe connection.

[0032] Finally, when the seat bracket is welded, the operator removes the welded seat bracket from the mounting block 6 .
