[0029] Working principle of this utility model:

[0030] Refer to the instruction manual Figure 1-5 When in use, the two metal pipes to be welded are fixed on the two driven gears 16 respectively, and the welding ends of the two metal pipes are located in the same straight line.

Therefore, the steel pipes are stable during the welding process and no gaps are generated. After the steel pipes are butted, the output shaft of the synchronous limit motor 18 drives the driving gear 20 to rotate, and the driving gear 20 drives the driven gear 16 to rotate through the toothed belt 21. 16 drives the rotating column 14 to rotate, and the rotating column 14 drives the two welded steel pipes to rotate through the three-jaw chuck 15. By automatically rotating the two metal pipes, there is no need to move the control computer 4 during the welding process, and the metal pipes can be automatically rotated. The metal pipes remain synchronized during the rotation process, and the welding gap of the metal pipes will not move, and the welding effect is good. The metal pipes rotate slowly after the docking is completed, and the control computer 4 on the gas welding machine body 2 is aligned with the welding part of the metal pipe for welding. After the metal pipes are welded, the clamping of the metal pipe by a three-jaw chuck 15 is released, the output shafts of the two hydraulic push rods 7 are contracted, and then the other three-jaw chuck 15 is released to take out the welded metal pipe.
