DETAILED DESCRIPTION

[0017] The utility model makes further detailed description in combination with the drawings.

[0018] Combined with appendix Figures 1-4 A laser cladding device for improving coating adhesion strength includes a connecting column 1. A laser cladding component 2 is connected to the bottom of the connecting column 1. The laser cladding component 2 contains a main laser 3 and a flow channel 4. A material input connecting pipe 5, which communicates with the flow channel 4, is connected to the top of the laser cladding component 2. The material input connecting pipe 5 is an external material conveying hose. A material nozzle 6, which communicates with the flow channel 4, is located outside the main laser 3 at the bottom of the laser cladding component 2. Generally, the cladding material is sprayed out through the material nozzle 6, and then the high-energy-density laser beam of the main laser 3 causes it to melt together with a thin layer on the surface of the substrate. The above structure is a conventional laser cladding device. The connecting column 1 generally needs to be connected to horizontal and vertical drive rails to drive the laser cladding component 2 to move horizontally and vertically to perform laser cladding operations.

[0019] The connecting column 1 is fixedly mounted on the top of the laser cladding component 2 with a driving cylinder 7. A rotating ring 8 is driven at the bottom of the driving cylinder 7. A rotating disk 17 is rotatably connected inside the driving cylinder 7. A geared ring 18 is connected to the rotating disk 17. A third motor 19 is connected to the top of the driving cylinder 7. The bottom power end of the third motor 19 has a gear 20 that meshes with the geared ring 18. That is, the rotation of the rotating disk 17 and the rotating ring 8 is driven by the third motor 19 in conjunction with the gear 20 and the geared ring 18. A support gear is required between the rotating disk 17 and the connecting column 1. A first support plate 9 is connected to one side of the bottom of the rotating ring 8. A heating and impurity removal laser 15, which can be raised, rotated, and has an adjustable angle, is located at the bottom of the first support plate 9. An electric push rod 10 is located at the top of the first support plate 9. The bottom power end of the electric push rod 10 extends to below the first support plate 9 and has a second support. The second support plate 11 has a first motor 12 fixedly mounted at its bottom. The power end of the first motor 12 has a third support plate 13. The bottom of the third support plate 13 is welded with a hinge 14 for damping the hinged heating and cleaning laser 15. The outside of the hinge 14 is connected to a second motor 16 that drives the heating and cleaning laser 15. The bottom structure is raised and lowered by an electric push rod 10, and the bottom structure is rotated by the first motor 12. The angle of the heating and cleaning laser 15 can be adjusted by the second motor 16 in conjunction with the hinge 14. That is, when the laser cladding part 2 is cladding, the heating and cleaning laser 15 is adjusted to a suitable position, specifically to the front of the forward direction of the laser cladding part 2. The heating and cleaning laser 15 irradiates the substrate to preheat and clean the surface of the substrate, thereby greatly improving the bonding between the filler cladding layer formed by the laser cladding part 2 and the substrate.

[0020] The second support plate 11 is provided with a plurality of limiting rods 21 on the top outer side, the first support plate 9 is welded with a limiting plate 22 for limiting the limiting rods 21, that is, the limiting rods 21 can be limited to lift inside the limiting plate 22, the connecting column 1 is rotatably connected with a limiting ring 23 below the driving cylinder 7, the limiting ring 23 and the connecting column 1 are jointly provided with a support bearing, and the first support plate 9 is fixedly provided with a support rod 24 fixedly connected with the top of the limiting ring 23, and the utility model can guarantee that the equipment runs more stably through the limiting structure.
