In addition, the design of the chute 26 facilitates the smooth sliding of the slide plate 201.

[0040] Working principle: Before using the device, first, place the pipe to be welded on the designated position of the U-shaped plate 3, which is located on the outside of the two rotating columns 6 and the moving wheel 9 to ensure good docking between the pipe and the rotating mechanism. Subsequently, the elastic strip 12 is passed through the hollow column 11 and firmly fixed with Velcro 13 to ensure that the pipe can be stably fixed on the top of the U-shaped plate 3 to avoid deviation during the rotation process. Immediately afterwards, by starting the servo motor 4, pulley 1 5 is driven to rotate. The rotation of pulley 1 5 is transmitted to pulley 2 7 through the transmission action of belt 8, so that pulley 2 7 also rotates. The rotation of pulley 2 7 further drives the rotating column 6 to rotate. The rotating column 6 serves as a bridge connecting the pipe and the rotating mechanism. Its rotation directly drives the outer pipe to rotate. Finally, the rotation of the rotating column 6 realizes the uniform rotation of the outer pipe. During the welding process, the uniform rotation of the pipe helps to ensure the uniformity of the weld and improves the welding quality and efficiency.

[0041] And through the adjustment mechanism 2, when the position of the welding device needs to be adjusted, starting the electric telescopic rod 207 can drive the slide plate 201 to move back and forth above the counter 1, and drive the upper structure to move synchronously. At the same time, by sliding the movable block 202 left and right, the position of the laser welding equipment 205 above the slide plate 201 can be adjusted to achieve horizontal adjustment, and the moved position can be fixed by tightening the stud 203. In addition, turning the adjustment knob 206 can release the fixed state of the laser welding equipment 205, so that it can rotate freely above the U-shaped block 204, thereby adjusting its angle. After the adjustment is completed, turning the adjustment knob 206 again can re-fix the laser welding equipment 205.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
