[0012] Furthermore, the side walls of the two fixed plates are fixedly connected with guide rods, and the surfaces of the guide rods are slidably connected with the movable plates.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0014] The utility model can automatically clamp the surface of the pipeline through the cooperation between the rotating disk, the open groove, the sliding sleeve and the clamping rod. Through this arrangement, the centers of the pipelines are placed on the same horizontal line, preventing the center offset problem caused by the difference in the sizes of the two pipelines, and further ensuring the quality of welding work.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 3 The utility model provides a technical solution: a heat pipe welding alignment device, comprising a support plate 1, a moving mechanism 2 is arranged on the top of the support plate 1, a moving plate 3 for driving is arranged on the surface of the moving mechanism 2, a clamping mechanism 4 is arranged on the side wall of the moving plate 3, and the clamping mechanism 4 is used to clamp the surface of the pipe: wherein the clamping mechanism 4 comprises a rotating disk 41 rotating on the surface of the moving plate 3, an open groove 42 is arranged around the rotating disk 41, a sliding sleeve 43 is connected to the inside of the opening groove 42 by rotating the shaft, and the inner sliding connection of the sliding sleeve 43 is provided. A clamping rod 44 is connected, and the end of the clamping rod 44 is rotatably connected to the surface of the movable plate 3 through a rotating shaft. By rotating the rotating disk 41 clockwise, the sliding sleeve 43 inside the opening groove 42 can be displaced. Since the clamping rod 44 is slidably connected inside the sliding sleeve 43, the angle of the clamping rod 44 can be changed, so that the clamping rods 44 are brought closer to each other, so that they can automatically fit on the surface of the pipe, thereby completing the clamping and fixing of the pipe, and automatically adjusting the center position to prevent the problem of offset caused by different centers of the two pipes.

[0023] according to Figure 1 It can be seen that the moving mechanism 2 includes two fixed plates 21 fixed on the top of the support plate 1, the side walls of the fixed plates 21 are fixedly connected to the servo motor 22, the output end of the servo motor 22 is fixedly connected to the bidirectional screw rod 23, the end of the bidirectional screw rod 23 is rotatably connected to the side wall of the fixed plate 21 through a bearing, and the moving plate 3 is threadedly connected to the surface of the bidirectional screw rod 23. The fixed plate 21 is used to support the servo motor 22, and then driven by the servo motor 22, the bidirectional screw rod 23 can be displaced, so as to move the moving plate 3, thereby realizing the adjustment of the spacing between the pipes, so as to facilitate better welding work.

[0024] according to Figure 2 It can be seen that the side wall of the rotating disk 41 is fixedly connected with a connecting block 46, and the surface of the connecting block 46 is rotatably connected with a cylinder 45 through a rotating shaft. The end of the cylinder 45 is rotated on the movable plate 3 through a rotating shaft, and driven by a rotating wheel 47 rotatably connected to the connecting block 46, the connecting block 46 can be rotated to a position, thereby driving the rotating disk 41 to rotate and move.

[0025] according to Figure 3 It can be seen that the inside of the clamping rod 44 is rotatably connected to a rotating wheel 47 via a rotating shaft. Under the setting of the rotating wheel 47, it can clamp the surface of the pipeline and rotate the pipeline, so that the pipeline can be welded in all aspects.

[0026] according to Figure 3 It can be seen that a cleaning wire brush 5 is fixedly connected to the bottom of the movable plate 3, and the cleaning wire brush 5 slides on the support plate 1. When the cleaning wire brush 5 is fixed on the movable plate 3, the cleaning wire brush 5 can be synchronously driven to move when the movable plate 3 moves, so as to clean the welding points on the support plate 1.

[0027] according to Figure 1 It can be seen that the side walls of the two fixed plates 21 are fixedly connected with guide rods 24, and the surfaces of the guide rods 24 are slidably connected to the movable plate 3. Under the setting of the guide rods 24, the guide rods 24 can play a guiding and limiting role when the movable plate 3 moves.

[0028] The working principle of the utility model is as follows: when in use, the support plate 1 is first fixed, and then the welded pipe is passed through the movable plate 3 and the clamping mechanism 4. At this time, the clamping mechanism 4 is rotated so that the pipe can be clamped and fixed. The outer group of pipes is clamped and fixed by the same method. At this time, the movable mechanism 2 is driven so that the two groups of pipe ports can be brought close to each other, so that it is convenient for welding. When the clamping mechanism 4 is specifically clamped, the sliding sleeve 43 inside the opening groove 42 can be displaced by the clockwise rotation of the rotating disk 41. Since the sliding sleeve 43 is internally slidably connected to the clamping rod 44, the angle of the clamping rod 44 can be changed, so that the clamping rods 44 can be brought close to each other, so that they can automatically fit on the surface of the pipe, thereby completing the clamping and fixing of the pipe, and automatically adjusting the center position to prevent the two pipe centers from being different and easily causing offset problems. On the contrary, the counterclockwise rotation of the rotating disk 41 can complete the release of the clamping of the pipe.
