Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1 - Figure 5 As shown, this utility model provides a technical solution for a special copper pipe welding equipment, including a base 1, with annular mounting brackets 2 on both sides of the top of the base 1, a rotating structure between the two annular mounting brackets 2, a welding structure on the top of the base 1, a sliding seat 11 inside the annular mounting bracket 2, an adjustment structure between the sliding seat 11 and the annular mounting bracket 2, a rotating column 13 rotatably connected to the top of the sliding seat 11, a first worm gear 14 fixedly connected to the outside of the rotating column 13, a first worm 15 meshingly connected to the outside of the first worm gear 14, support blocks rotatably connected to both ends of the outside of the first worm 15, both support blocks being fixedly connected to the sliding seat 11, a first throttle handle installed at one end of the first worm 15, and a mounting base 12 fixedly connected to the top of the rotating column 13, with a clamping structure on the top of the mounting base 12.

[0024] The clamping structure includes a cross groove 16, which is located on the top of the mounting base 12. A bidirectional screw 17 is provided inside the cross groove 16, and both ends of the bidirectional screw 17 are rotatably connected to the mounting base 12. A third worm gear 20 is fixedly connected to the bidirectional screw 17, and a third worm 21 is meshed with the outside of the third worm gear 20. One end of the third worm 21 passes through the inside of the cross groove 16 and extends to the outside of the mounting base 12. The third worm 21 is rotatably connected to the mounting base 12, and a third throttle is installed at one end of the third worm 21. The clamping structure also includes two cross blocks 18, which are threaded to the outside of the bidirectional screw 17.

A mounting block 19 is fixedly connected to the top of the cross block 18, and two clamps 190 are fixedly connected to the top of the mounting block 19.

[0025] Specifically, when the third throttle is turned, the third worm 21 meshes with the third worm wheel 20, and the third worm wheel 20 drives the bidirectional screw 17 to rotate. The bidirectional screw 17 is threadedly connected to two cross blocks 18. Both cross blocks 18 slide inside the cross groove 16. The two cross blocks 18 drive multiple clamps 190 to move in opposite directions through two mounting blocks 19. The multiple clamps 190 clamp and fix the copper tube.

[0028] Specifically, by rotating the second throttle, the second worm gear 10 meshes with the second worm wheel 9. The second worm wheel 9 drives the threaded rod 8 to rotate on the fixed seat 6 and the annular mounting bracket 2. The threaded rod 8 is threadedly connected to the sliding seat 11. The sliding seat 11 drives the mounting seat 12 to make longitudinal fine adjustments through the rotating column 13, so that one end of the irregular copper tube to be welded is aligned with the straight copper tube and is located at the center of the annular mounting bracket 2, so as to facilitate subsequent rotational welding.

[0029] Example: Figure 1 - Figure 4 As shown, the rotating structure includes two fixed plates 3, which are rotatably connected to the outside of two annular mounting brackets 2.

[0030] The welding structure includes a sliding frame 25, which is fixedly connected to the top of the base 1. An L-shaped plate 24 is slidably connected to the outside of the sliding frame 25. A second hydraulic rod 26 is fixedly connected to the top of the sliding frame 25. The telescopic end of the second hydraulic rod 26 is fixedly connected to the L-shaped plate 24. A first hydraulic rod 22 is installed on the L-shaped plate 24. A welding head 23 is installed at the bottom of the first hydraulic rod 22.

[0031] Specifically, the motor is started. The specific motor model is not limited, but is based on the compatible equipment. The output end of the motor drives the rotating shaft 4 to rotate on the two fixed plates 3. The rotating shaft 4 drives the two small gears 5 to rotate. The two small gears 5 mesh with the two large gears 50 respectively, thereby realizing the simultaneous rotation of the two annular mounting brackets 2. Thus, the copper tubes to be connected can be rotated so that the welding head 23 can be welded.
