[0039] The centers of the upper and lower welding modules 6 and the alignment guide groove 4 are located on the same horizontal plane, which can effectively provide accuracy in subsequent welding alignment and positioning of the pipe.

[0040] The two sets of limit guide seats 39 are adapted to the bidirectional screw rod 2 through the ball slide 36 and then threadedly slidably connected to the upper end surface of the fixed base 9, so that the two sets of limit guide seats 39 can quickly and accurately align and position the internally limited pipes, thereby improving the stability of subsequent welding of the pipe body.

[0044] Working principle: Before use, the staff can position the external small-diameter tube body guide module to the front and rear of the fixed base 9. The guide module can facilitate the subsequent rapid loading and unloading operations of the tube body. When the tube body is loaded, the servo motor 38 is started, and the servo motor 38 can drive the active gear 34 to rotate. At the same time, the active gear 34 can be connected to the driven gear 312 through meshing, thereby driving the active bevel gear 33 to rotate.

After the alignment is completed, the dual-axis motor 8 can drive the upper and lower welding modules 6 to move centripetally through the threaded slide 7, so that the welding module 6 can be docked to the gap where the two sets of tube bodies are docked. Subsequently, the three sets of stepper motors 323 are started synchronously, and the stepper motors 323 can drive the two sets of guide gears 325 to rotate synchronously through the transmission gear 324. The two sets of guide gears 325 can drive the limited tube body to rotate stably through the limiting guide roller 326. At this time, the welding module 6 can stably weld the tube body.
