[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

The mounting seat 6 is mounted on both sides of the top of the base plate 1, and a rotating ring 7 is provided on the inner side of the mounting seat 6. The transmission gear ring 18 is installed on the outer side wall of the rotating ring 7. A driving gear 19 is installed on one side above the mounting seat 6. The transmission gear ring 18 and the driving gear 19 are meshed with each other. A transmission rod 20 is installed at one end of the driving gear 19, and a third bevel gear 21 is installed at the middle position of the transmission rod 20. The fourth bevel gear 22 is meshed below the third bevel gear 21, and a second servo motor 23 is installed at the bottom end of the fourth bevel gear 22. When in use, start the second servo motor 23 to drive the fourth bevel gear 22 to rotate. Since the fourth bevel gear 22 and the third bevel gear 21 are meshed with each other, the third bevel gear 21 is used to drive the transmission rod 20 to rotate, and then the two active gears 19 are driven to rotate. Since the transmission gear ring 18 and the active gear 19 are meshed with each other, under the limitation of the limit ring 24 and the limit rail 25, the transmission gear ring 18 is used to drive the rotating ring 7 to rotate, and then the ultra-thin narrow and long pipeline is driven to rotate, and then the ultra-thin narrow and long pipeline is fully welded, which can drive the clamped ultra-thin narrow and long pipeline to rotate, so that the ultra-thin narrow and long pipeline is more comprehensive when spot welding, and the ultra-thin narrow and long pipeline is more efficient when spot welding, thereby greatly improving the working efficiency of the device when in use.

[0020] The limiting structure includes a limiting ring 24 and a limiting rail 25. The limiting ring 24 is opened inside the mounting seat 6. The limiting rail 25 is arranged inside the limiting ring 24. The limiting rail 25 is arranged on the outer wall of the rotating ring 7. The inner diameter of the limiting ring 24 is larger than the outer diameter of the limiting rail 25. A sliding structure is formed between the limiting ring 24 and the limiting rail 25.

[0021] The clamping mechanism includes an installation cavity 8, a clamping plate 9, a first servo motor 10, a first bevel gear 11, a second bevel gear 12, a threaded rod 13, a threaded sleeve 14, a movable cavity 15 and a guide structure. The installation cavity 8 is installed on both sides of the rotating ring 7. The first servo motor 10 is installed above the installation cavity 8. The first bevel gear 11 is installed on one side of the top of the installation cavity 8. The output end of the first servo motor 10 is connected to one end of the first bevel gear 11.

A threaded sleeve 14 is provided on the outer wall of the threaded rod 13. The movable cavity 15 is fixedly installed on the outer wall of the threaded sleeve 14. One end of the movable cavity 15 extends to the outside of the installation cavity 8. When the clamping plate 9 is in use, the two ultra-thin narrow and long pipes are passed through the inner sides of the two rotating rings 7 respectively, and one end of each pipe is placed on the supporting block 2, and then the welding points of the two ultra-thin narrow and long pipes are fitted together. At this time, the first servo motor 10 is started to drive the first bevel gear 11 to rotate, thereby driving the second bevel gear 12 to rotate, and then the second bevel gear 12 is used to drive the threaded rod 13 to rotate, thereby driving the threaded sleeve 14 to move. Under the limitation of the guide groove 16 and the guide block 17, the threaded sleeve 14 is used to drive the moving cavity 15 to move, thereby driving the clamping plate 9 to move, and the two clamping plates 9 are used to clamp the ultra-thin narrow and long pipes, so that the ultra-thin narrow and long pipes are more stable during welding. At the same time, the design of the rotating ring 7 and the clamping plate 9 can clamp and fix longer pipes, thereby greatly improving the practicality of the device when in use.

[0022] The guide structure includes a guide groove 16 and a guide block 17. The guide groove 16 is opened above and below the inside of the installation cavity 8. The guide block 17 is arranged inside the guide groove 16. One end of the guide block 17 is connected to one end of the movable cavity 15. When in use, the movable cavity 15 can be guided when moving by utilizing the mutual cooperation between the guide groove 16 and the guide block 17, so that the movable cavity 15 is more stable when moving.

[0023] The clamping plate 9 is designed to be arc-shaped on the inner side of the rotating ring 7, and a plastic cushion is arranged on the inner side of the clamping plate 9. The design of the plastic cushion makes it difficult for the ultra-thin narrow and long pipe to be damaged when clamping.

[0024] Working principle: The staff first passes the two ultra-thin narrow and long pipes through the inner side of the two rotating rings 7 respectively, places one end of them on the support block 2, and then fits the welding parts of the two ultra-thin narrow and long pipes together. At this time, the first servo motor 10 is started to drive the first bevel gear 11 to rotate, thereby driving the second bevel gear 12 to rotate, and then the second bevel gear 12 is used to drive the threaded rod 13 to rotate, thereby driving the threaded sleeve 14 to move. Under the limit of the guide groove 16 and the guide block 17, the threaded sleeve 14 is used to drive the moving cavity 15 to move, thereby driving the clamping plate 9 to move, and the two clamping plates 9 are used to clamp the ultra-thin narrow and long pipes. At this time, the gas can be started. The cylinder 4 moves downward, and the cylinder 4 is used to perform spot welding on the ultra-thin narrow and long pipe. When the ultra-thin narrow and long pipe needs to be rotated, the second servo motor 23 is started to drive the fourth bevel gear 22 to rotate. Since the fourth bevel gear 22 and the third bevel gear 21 are meshed with each other, the third bevel gear 21 is used to drive the transmission rod 20 to rotate, and then the two driving gears 19 are driven to rotate. Since the transmission gear ring 18 and the driving gear 19 are meshed with each other, the transmission gear ring 18 is used to drive the rotating ring 7 to rotate under the limitation of the limiting ring 24 and the limiting rail 25, and then the ultra-thin narrow and long pipe is driven to rotate, and then the ultra-thin narrow and long pipe is fully welded.
