Description

Technical Field

[0001] This utility model relates to the field of pipeline cladding technology, and in particular to a laser cladding device for the inner hole of a pipeline. Background Technology

[0002] Laser cladding, also known as laser welding or laser coating, is a novel surface modification technology. It involves adding a cladding material to the surface of a substrate and then using a high-energy-density laser beam to fuse the material with a thin layer on the substrate surface, forming a metallurgically bonded cladding layer. To achieve specific strength or corrosion resistance, pipelines undergo laser cladding on their inner walls to form a protective cladding layer.

[0003] The prior art, disclosed in CN221398053U, discloses a laser cladding device for the inner hole of a pipe. However, its shortcomings are that when it is necessary to move the laser cladding head placed inside the pipe, the positioning roller makes the movement inconvenient. Furthermore, the pipe needs to be passed through a three-jaw chuck each time it is picked up or placed, which is very inconvenient for the placement of the pipe. Therefore, this application proposes a laser cladding device for the inner hole of a pipe. Utility Model Content

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a laser cladding device for the inner hole of a pipe, comprising:

[0023] Rack 1,

[0024] A drive assembly mounted on a frame 1 drives the rotation of the pipeline. The drive assembly includes a support mechanism mounted on the frame 1, which is ingeniously designed to provide efficient and stable support for the pipeline. Specifically, the support mechanism includes multiple carefully arranged tilting frames 15, which are securely fixed in predetermined positions on the frame 1. Each tilting frame 15 is rotatably mounted with a support roller 16, which is not only smooth but also made of wear-resistant material, ensuring low friction and high durability when in contact with the pipeline.

[0025] Of particular note is the unique figure-eight arrangement of the tilting brackets 15. This design is not only aesthetically pleasing, but more importantly, it enables a more balanced and stable support effect during pipe placement through the multi-point contact of the support rollers 16.

[0026] A mounting frame 2 is installed on the frame 1. A first driving component 3 is installed on the mounting frame 2. A U-shaped plate 12 is installed at the output end of the first driving component 3. A pressure roller 13 that is driven to rotate is installed on the U-shaped plate 12. A motor 14 is installed on the U-shaped plate 12. The output end of the motor 14 is fixedly connected to the pressure roller 13. The first driving component 3 drives the U-shaped plate 12 to move downward so that the pressure roller 13 abuts against the upper end of the pipe. The motor 14 works to drive the pressure roller 13 to rotate, and the pressure roller 13 can drive the pipe to rotate. A guide rail can be installed on the mounting frame 2. A guide block slides on the guide rail and is fixed to the U-shaped plate 12, so that the U-shaped plate 12 can move up and down stably.

[0027] Laser cladding assembly; The laser cladding assembly includes a movable plate 6 movably mounted on a frame 1, a support plate 4 mounted on a bracket 1, the movable plate 6 sliding on the support plate 4, and an electric slide rail 5 mounted on the support plate 4. An electric slider fixedly connected to the movable plate 6 slides on the electric slide rail 5, and the movement of the electric slider can drive the movable plate 6 to move.

[0028] The movable plate 6 is equipped with a second driving component 7. The first driving component 3 and the second driving component 7 are electric push rods, cylinders or hydraulic cylinders, which can be selected according to the requirements. The second driving component 7 can drive the movable rod 9 to move up and down.

[0029] The output end of the second driving component 7 is fixed with a guided moving rod 9. The end of the moving rod 9 is equipped with a laser cladding head 11 and two support wheels 10. The laser cladding head 11 is located between the two support wheels 10. The inner wall of the pipe can be treated through the laser cladding head 11.

[0030] In use, the pipe is placed on the support roller 16 from one side, and then the electric slider moves on the electric slide rail 5 to drive the moving plate 6 to move. The movement of the moving plate 6 drives the second drive component 7, the moving rod 9, the laser cladding head 11 and the two support wheels 10 to move into the pipe until the laser cladding head 11 moves to the position of the pipe that needs to be treated. Then the second drive component 7 drives the moving rod 9 to move down. A guide rod 8 is fixedly connected to the moving plate 6. The guide rod 8 passes through the moving rod 9 and is slidably connected to it. Under the guidance of the guide rod 8, the moving rod 9 moves up and down stably until the support wheel 10 abuts against the inner wall of the pipe.

[0031] Then the first driving component 3 drives the U-shaped plate 12 to move down so that the pressure roller 13 abuts against the upper end of the pipe. The motor 14 works to drive the pressure roller 13 to rotate. The pressure roller 13 can drive the pipe to rotate. The inner wall of the pipe can be treated through the laser cladding head 11.

[0032] When it is necessary to adjust the position of the pipe cladding, the second drive component 7 drives the moving rod 9, the laser cladding head 11 and the two support wheels 10 to move upward so that they do not collide with the pipe. The electric slider moves again to adjust the position of the moving rod 9, the laser cladding head 11 and the two support wheels 10. Since the support wheels 9 do not collide with the pipe, the adjustment and movement are more convenient.

[0033] After processing, all mechanisms are reset, and the pipe can be removed from one side, which is convenient and quick.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
