A laser cladding device

Abstract

The invention provides a laser cladding device, which includes a base, a mounting frame, a fixture body, a rotating motor, a guide frame, a carriage, a laser cladding head, a powder feeding pipe, a support hoop, a guide arc plate and an annular thread block; two The set of mounting frames is set on the base, the two sets of fixture bodies are respectively rotatably connected to the two sets of mounting frames, the guide frame is erected horizontally between the two sets of mounting frames, and the carriage is horizontally slidably connected to the guide frame, and the supporting hoop includes: Two groups of hoop units hinged at the bottom of the carriage, bolts that close and connect the bottom ends of the two groups of hoop units, and sliding surfaces located on the inner sides of the two groups of hoop units; one of the clamp bodies is sleeved and fixed with a ring Threaded block, the circumferential outer wall of the annular threaded block is also provided with external threads, at least one set of guide arc plates is provided, and its arc-shaped inner wall is provided with external threads. Uneven cladding is caused by clamping at both ends of the part or thermal deformation of cladding.

[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
