Laser cladding device

Abstract

The invention provides a laser cladding device. The laser cladding device comprises a base, mounting racks, clamp bodies, a rotating motor, a guiding rack, a sliding rack, a laser cladding head, a powder feeding pipe, a supporting hoop, a guiding arc plate and an annular threaded block; the two mounting racks are arranged on the base, the two clamp bodies are rotationally connected onto the two mounting racks respectively, the guiding rack is horizontally arranged between the two mounting racks, the sliding rack is connected onto the guiding rack in a horizontal sliding manner, and the supporting hoop comprises two hoop units hinged to the bottom of the sliding rack, bolts for closed connection of the bottom ends of the two hoop units and sliding surfaces located on the inner sides of thetwo hoop units; one clamp body is sleeved and fixed with the annular threaded block, an external thread is formed in the circumferential outer wall of the annular threaded block, at least one guidingarc plate is arranged, and an internal thread matched with the external thread is formed in the arc inner side wall of the at least one guiding arc plate. The laser cladding device is simple in structure, and has low probability of causing the phenomenon of uneven cladding under influence of clamping by two ends of a slender shaft part or cladding heat deformation.

[0002] Laser cladding (Laser cladding), also known as laser cladding or laser cladding, is a new surface modification technology; The method of melting and coagulating the thin layers on the surface of the material forms a metallurgically bonded cladding layer on the surface of the base layer, and the resulting cladding layer has low dilution but strong bonding force, and is metallurgically bonded to the substrate, which can significantly improve the surface of the substrate material. Wear resistance, corrosion resistance, heat resistance, oxidation resistance or electrical properties, so as to achieve the purpose of surface modification or repair, meet the specific performance requirements of the material surface and save a lot of material costs; and surfacing, spraying, electroplating and vapor deposition In comparison, laser cladding has the characteristics of small dilution, dense structure, good combination of coating and substrate, many materials suitable for cladding, and large changes in particle size and content. Therefore, the application prospect of laser cladding technology is very broad; but currently for slender In the cladding technology of shaft parts, since the fixture is generally clamped on both ends of the shaft by the fixture when fixing the part, a certain degree of bending deformation will be formed due to the influence of gravity in the middle of the slender shaft itself, especially When the laser cladding head is cladding from one end to the other, the heat generated will also aggravate such deformation, which will cause uneven thickness during the cladding operation and affect the quality of cladding
