One side of the frame 1 is rotatably connected with a penetrating mounting cylinder 6. The bottom of the frame 1 is provided with a support plate, and the surface of the support plate is provided with fixing holes for fixing the frame 1. One side of the mounting cylinder 6 is slidably connected with a plurality of clamping brackets 10 for clamping the pipe. The clamping brackets 10 are L-shaped and are used to clamp and fix the pipe. The bottom of one of the clamping brackets 10 is slidably connected with a penetrating limiting frame 15. The limiting frame 15 is L-shaped and is used to limit the pipe. The top of the clamping bracket 10 where the limiting frame 15 is installed is provided with a sliding groove and a threaded hole on the side. The top of the limiting frame 15 is fixedly connected with a pushing block 16. The pushing block 16 is slidably connected with the sliding groove. A top screw is threadedly connected in the threaded hole and abuts against the limiting frame 15. When the limiting frame 15 slides, the position of the limiting frame 15 can be adjusted, so as to adapt to pipes of different lengths and keep the weld seam below the welding gun 4;

[0025] One side of the mounting cylinder 6 is rotatably connected with a rotating ring 11. A plurality of inclined slots 12 are opened on one side of the rotating ring 11. One side of each clamping bracket 10 is fixedly connected with an adjusting rod 13. The plurality of adjusting rods 13 slide in the inclined slots 12 respectively. By pressing down the adjusting rods 13 through the inclined slots 12, the plurality of clamping brackets 10 move towards the middle, thereby clamping and fixing the pipe, which is convenient to use.

[0026] In the present utility model, a plurality of second teeth 14 are fixedly installed around the circumference of the swivel ring 11. One side of the mounting cylinder 6 is rotatably connected to a mounting shaft 18. A second gear 19 is fixedly connected around the circumference of the mounting shaft 18. The second gear 19 meshes with the second teeth 14. The second gear 19 drives the mounting cylinder 6 to rotate through the second teeth 14, and the mounting cylinder 6 drives the inclined groove 12 to rotate.

[0027] In particular, a worm 20 is rotatably connected to one side of the mounting cylinder 6. A worm gear 21 is fixedly connected around the circumference of the mounting shaft 18. The worm gear 21 meshes with the worm 20. By rotating the worm 20, the worm 20 drives the second gear 19 to rotate through the worm gear 21. At the same time, the self-locking effect of the worm gear 21 and the worm 20 is utilized to improve the clamping stability.

[0030] In particular, a plurality of first teeth 7 are fixedly arranged around the circumference of the mounting cylinder 6. A motor 8 is fixedly connected to one side of the frame 1. One end of the output shaft of the motor 8 is fixedly connected to a first gear 9. The first gear 9 meshes with the first teeth 7. By starting the motor 8, the motor 8 drives the first gear 9 to rotate. The first gear 9 drives the mounting cylinder 6 to rotate through the first teeth 7, and the mounting cylinder 6 drives the pipe to rotate.

[0031] It should be noted that a protective shell 5 for enclosing the first teeth 7 is fixedly connected to one side of the frame 1. The protective shell 5 improves the safety of equipment operation.

[0032] Working principle: When in use, first clamp the pipes spot-welded together on the clamping bracket 10. During clamping, rotate the worm 20. The worm 20 drives the second gear 19 to rotate through the worm gear 21. The second gear 19 drives the mounting cylinder 6 to rotate through the second teeth 14. The mounting cylinder 6 drives the inclined groove 12 to rotate. The adjusting rod 13 is pressed down through the inclined groove 12, so that a plurality of clamping brackets 10 move towards the middle, thereby clamping and fixing the pipes. After fixing, start the motor 8. The motor 8 drives the first gear 9 to rotate. The first gear 9 drives the mounting cylinder 6 to rotate through the first teeth 7. The mounting cylinder 6 drives the pipes to rotate. Then start the power push rod 3 to lower the welding gun 4, and weld the pipes through the welding gun 4. When sliding the limit bracket 15, the position of the limit bracket 15 can be adjusted to adapt to pipes of different lengths and keep the weld seam below the welding gun 4.
