Laser cladding device with adjustable wire outlet direction

Abstract

The invention discloses a laser cladding device with an adjustable wire outlet direction. The laser cladding device comprises a three-beam laser cladding spray head, wherein the three-beam laser cladding spray head is connected with a wire nozzle through a wire guide column; a wire inlet hole is formed in one side of the wire guide column, and a wire passage is formed in the middle of the wire guide column; a wire for cladding enters the wire passage from the wire inlet hole and is ejected through the wire nozzle; an incident laser beam generates three beams through the three-beam laser cladding spray head, and the three beams are projected below the wire nozzle and envelope the wire ejected from the wire nozzle; and the wire guide column is movably connected with the three-beam laser cladding spray head. The laser cladding device disclosed by the invention is adopted with another idea, and the position of the wire ejected from the wire nozzle is adjusted, so that the position relationship between a laser beam spot and the wire is adjusted, and a good envelope relationship between the spot and the wire can be obtained without adjusting a precise optical assembly.

Description

technical field [0001] The invention belongs to the technical field of laser cladding, and in particular relates to a laser cladding device. Background technique [0002] Laser cladding (also known as laser cladding or laser cladding) is a new surface modification technology. It forms a metallurgically bonded cladding layer on the surface of the base by adding cladding materials on the surface of the substrate and using a high-energy-density laser beam to fuse it together with the thin layer on the surface of the substrate. [0003] Laser cladding features: the cladding layer has low dilution but strong binding force, and is metallurgically bonded to the substrate, which can significantly improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance or electrical properties of the substrate material surface, so as to achieve surface modification or The purpose of repair is to meet the specific performance requirements of the material surface and s...

AI Technical Summary

Problems solved by technology

The existing adjustment method is to manually adjust the optical components inside the laser cladding device. Since the optical components are precision and expensive components, they are easily damaged after repeated adjustment operations, which increases the risk of paying expensive maintenance costs.

Moreover, the operation of optical devices often requires very small and precise operations, which requires high skills for technicians
