A support plate 45 is rotatably installed at one end of the rotating rod 43. The lower surface of the support plate 45 is fixedly connected to the upper surface of the base 1. A sliding groove 44 is provided on the outer surface of the rotating rod 43. A slider 47 is slidably installed on the inner wall of the sliding groove 44. A moving gear 48 is slidably installed on the outer surface of the rotating rod 43. The inner surface of the moving gear 48 is fixedly connected to the outer surface of the slider 47.

The moving gear 48 and the fixed gear 46 are respectively meshed with two gear rings 36.

[0034] The specific implementation method is as follows: the drive motor 42 drives the rotating rod 43 to rotate. Under the action of the slide groove 44 and the slider 47, the rotating rod 43 drives the moving gear 48 to rotate, and at the same time, it also drives the fixed gear 46 to rotate synchronously.

[0035] The cooling assembly 6 includes a piston box 61 and a support sleeve 68.

One end of the movable rod 67 is rotatably mounted with a connecting rod 66 via a rotating shaft. One end of the connecting rod 66 is rotatably mounted with a mounting clamp 65 via a rotating shaft. A fixing plate 64 is fixedly mounted on the side wall of the piston box 61. One end of the connecting rod 66 passes through the interior of the fixing plate 64.

The first toothed sprocket 610 and the second toothed sprocket 612 are connected by a toothed chain drive.

[0036] The specific implementation method is as follows: When the rotating rod 43 rotates, it drives the second toothed sprocket 612 to rotate synchronously. Under the action of the toothed chain, it drives the first toothed sprocket 610 to rotate, thereby driving the mounting rod 69 to rotate on the inner wall of the support sleeve 68. The mounting rod 69 drives the rotating disk 611 to rotate synchronously. As the rotating disk 611 rotates, the movable rod 67 drives the connecting rod 66 to move back and forth under the limit of the fixed plate 64, thereby driving the piston plate 63 to move back and forth in the piston box 61 through the mounting clamp 65. Gas is drawn into the piston box 61 through the air inlet pipe, and then blown onto the outer surface of the weldment through the air outlet on the air outlet pipe 62, so as to achieve a certain cooling effect on the weldment.

[0037] The adjusting assembly 2 includes a support base 21, the lower surface of which is fixedly connected to the upper surface of the base 1. A travel groove 22 is provided on the upper surface of the support base 21. A threaded post 23 is rotatably mounted on the inner wall of the travel groove 22. One end of the threaded post 23 extends to the outside of the support base 21. A threaded sleeve 24 is threadedly mounted on the outer surface of the threaded post 23. The outer surface of the threaded sleeve 24 is slidably connected to the inner wall of the travel groove 22. The lower surface of one support post 31 is fixedly connected to the upper surface of the support base 21, and the lower surface of the other support post 31 is connected to the threaded sleeve. The upper surface of 24 is fixedly connected. The clamping assembly 5 includes a mounting plate 51. The side wall of the mounting plate 51 is fixedly connected to the inner surface of the rotating ring 34. A threaded rod 52 is threadedly installed on the inner surface of the mounting plate 51. A clamping plate 53 is rotatably installed at one end of the threaded rod 52. A connecting spring 54 is fixedly installed on the side wall of the clamping plate 53. A fixing plate 55 is fixedly installed at one end of the connecting spring 54. A movable pin 56 is fixedly installed on the side wall of the fixing plate 55. One end of the movable pin 56 passes through the interior of the connecting spring 54 and extends to the outside of the other side wall of the clamping plate 53.

[0038] The specific implementation method is as follows: Place one end of each of the two workpieces to be welded between the two clamping plates 53, and then rotate the threaded rod 52. The threaded rod 52 will move on the mounting plate 51, thereby driving the clamping plate 53 to move towards the center position of the rotating ring 34. As the clamping plate 53 moves, it will clamp the workpiece. At this time, the movable pin 56 on the clamping plate 53 will extend and retract according to the shape of the workpiece under the action of the connecting spring 54, thereby deforming the movable pin 56 on the clamping plate 53 according to the shape of the workpiece, so that the clamping plate 53 and the workpiece fit together better. Then, the threaded column 23 will rotate in the stroke groove 22. Under the action of the thread, the threaded sleeve 24 will be displaced in the stroke groove 22, thereby driving the support column 31 to move. When the support column 31 moves, it drives the workpiece to move, so that the welding surfaces of the two workpieces fit together and are then welded.

[0039] Working principle: Place one end of each of the two workpieces to be welded between two clamping plates 53. Rotating the threaded rod 52 moves the clamping plates 53, clamping them as they continue to move. The movable pin 56 on the clamping plate 53, under the action of the connecting spring 54, extends and retracts according to the shape of the workpiece, making the clamping plate 53 fit more closely to the workpiece. The threaded column 23 then rotates within the travel groove 22. Under the action of the thread, the threaded sleeve 24 displaces within the travel groove 22, moving the support column 31. The support column 31 moves synchronously, causing the fixed plate 64 to move. The fixed plate 64 moves via the positioning plate 410, driving the moving gear 48. The moving gear 48 slides within the groove 44 of the rotating rod 43 via the slider 47. Once the weld seams of the two workpieces are joined, welding is performed. During welding, the drive motor 42 rotates the rotating rod 43, which in turn moves the moving gear 48 via the slider 47. The moving gear 48 and the fixed gear 46 rotate synchronously. Under the action of the gear ring 36, the two rotating rings 34 rotate synchronously on the connecting plate 33 through the pulley 37 and the positioning rod 38, thereby driving the mounting plate 51 to rotate synchronously. As the mounting plate 51 rotates, it drives the weldment to rotate, realizing the weldment to flip while welding. When the rotating rod 43 rotates, it drives the second gear sprocket 612 to rotate synchronously. Under the action of the gear chain, it drives the first gear sprocket 610 to rotate, thereby driving the mounting rod 69 to rotate on the inner wall of the support sleeve 68. The mounting rod 69 drives the rotating disk 611 to rotate synchronously. As the rotating disk 611 rotates, the moving rod 67 drives the connecting rod 66 to move back and forth under the limit of the fixed plate 64, thereby driving the piston plate 63 to move back and forth in the piston box 61 through the mounting clamp 65. Gas is drawn into the piston box 61 through the air inlet pipe, and then blown onto the outer surface of the weldment through the air outlet on the air outlet pipe 62, so as to achieve a certain cooling effect on the weldment.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
