[0028] Furthermore, by placing the pipe to be welded on the top of the welding table 2 inside the supporting blocks 21 on both sides, the limiting grooves 211 are used to limit the pipe so that it will not move. Then, the extension plates 23 on both sides are moved according to the length of the pipe under the activation of the electric telescopic rod 22 until both ends of the pipe are engaged in the engaging grooves 233, so as to facilitate fixing and clamping according to the length of the pipe.

[0029] Example 2

[0030] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the rotating unit includes a groove 231 arranged on the inner side of the extension plate 23, a rotating ring 232 is rotatably installed inside the groove 231, a snap-fit ​​groove 233 is provided inside the rotating ring 232, a rubber pad 234 is fixedly installed on the inner wall of the snap-fit ​​groove 233, a supporting plate 235 is fixedly installed on the outer side of the extension plate 23, a driving motor 236 is fixedly installed on the top of the supporting plate 235, a driving rod 237 is fixedly installed on the output end of the driving motor 236, and the other end of the driving rod 237 is fixedly installed on the inner outer surface of the rotating ring 232.

[0031] Furthermore, when the welding assembly 3 is welding the pipe, the output end of the driving motor 236 is used to drive the driving rod 237 to rotate, thereby driving the rotating ring 232 to rotate. The rotating ring 232 drives the pipe to rotate at the same time, which is convenient for adjusting the welding angle. The rubber pad 234 on the inner wall of the rotating ring 232 fits against the outer surfaces of both ends of the pipe, which can enhance the friction and make the pipe rotate stably.

In the process of welding the pipe with the welding assembly 3, the output end of the driving motor 236 is used to drive the driving rod 237 to rotate, thereby driving the rotating ring 232 to rotate, and the rotating ring 232 drives the pipe to rotate at the same time, so as to facilitate adjusting the welding angle. The rubber pads 234 on the inner wall of the rotating ring 232 are attached to the outer surfaces of the two ends of the pipe, which can enhance the friction and make the pipe rotate stably. When the pipe rotates, its outer surface contacts the roller 214 on the top of the supporting block 21, and the rotation causes the roller 214 to rotate, further reducing the friction with the pipe and improving the smoothness of rotation.
