Without a fixing mechanism, the pipes are at risk of moving, resulting in a larger weld seam that affects the welding quality. In addition, the position to be welded when manually flipped is prone to change, which also affects the welding quality of the plate. Utility Model Content

[0024] The clamping assembly 4 includes symmetrically arranged fixing plates 401. The upper and lower side walls of the fixing plates 401 are fixedly connected to the inner ring side wall of the toothed ring 3. An electric telescopic rod 402 is fixedly connected through the middle of the two fixing plates 401. An arc-shaped clamping plate 403 is fixedly connected to the movable end of the two electric telescopic rods 402. The two arc-shaped clamping plates 403 are arranged symmetrically. In use, the electric telescopic rod 402 is powered by an external power source through a slip ring structure.

[0025] The drive device 5 includes a servo motor 501, the output end of which is fixedly connected to a rotating shaft 502, and the other end of the rotating shaft 502 is rotatably connected to a rotating connecting plate 504. The bottom ends of the servo motor 501 and the rotating connecting plate 504 are respectively fixedly connected to the middle upper surface of the two Y-shaped brackets 2. Two gears 503 are fixedly connected to the outer side wall of the rotating shaft 502. The two gears 503 are respectively located below the two gear rings 3, and the side wall of the gear 503 meshes with the side wall of the gear ring 3.

The controller 8 is electrically connected to the servo motor 501, the electric telescopic rod 402, the electric telescopic rod 701, and the welding torch 703. When welding two pipes using the clamping assembly 4 and welding assembly 7, one pipe is first clamped and fixed using the clamping assembly 4 on one side.

[0027] Working principle: In use, firstly, the clamping component 4 on one side is used to clamp and fix a pipe. The two electric telescopic rods 402 drive the two arc-shaped clamping plates 403 to move towards each other. Then, one end of another pipe is placed against the clamped pipe at the welding point. Next, the clamping component 4 on the other side is used to clamp it. During welding, the electric telescopic rod 701 pushes the welding gun 703 downward to weld the joint. When the pipe is flipped, the servo motor 501 drives the rotating shaft 502 to rotate, which drives the two gears 503 to rotate, and then drives the two gear rings 3 to rotate synchronously, stabilizing the welding position of the flipped pipe and improving the welding quality.
