Laser cladding device

Abstract

The invention relates to a laser cladding device. The device comprises a supporting seat and a nozzle located below the supporting seat. A beam splitter mirror, at least two reflection focusing mirrors and adjusting supports each used for fixing and adjusting the position of the corresponding reflection focusing mirror are arranged on the supporting seat. The beam splitter mirror receives an incident beam and reflects the incident beam to form a reflection beam. The reflection focusing mirrors receive the reflection beam and convert the reflection beam into a focusing beam. According to the device, the up-and-down position of each reflection focusing mirror is adjusted through a first rotary shaft and first adjusting parts on the corresponding adjusting support, the circumferential position of each reflection focusing mirror is adjusted through second adjusting parts and an arc groove or second adjusting parts, an arc groove and a second rotary shaft, and therefore the angle precision and position precision between an indexing plane of the beam splitter mirror and focusing faces on the focusing mirrors meet the design requirements; and therefore, cladding focusing points formed by the multiple focusing mirrors are gathered into one point, a cladded material is fully surrounded, and starting of high-precision laser cladding work is guaranteed.

Description

technical field [0001] The invention relates to a laser cladding device, which belongs to the field of laser processing. Background technique [0002] Laser cladding refers to placing the selected coating material on the surface of the substrate to be clad in different ways, and then irradiating it with laser to melt it and a thin layer on the surface of the substrate at the same time, and form a very low dilution after rapid solidification. The surface coating that forms a metallurgical combination with the substrate can significantly improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical properties of the base surface, so as to achieve the purpose of surface modification or repair. Laser cladding can be roughly divided into two categories according to the supply method of cladding materials, namely preset laser cladding and synchronous laser cladding. Pre-set laser cladding is to pre-place the cladding material on the cladd...

AI Technical Summary

Problems solved by technology

[0008] Due to the existence of manufacturing errors, in the process of assembly and use, the positional relationship between the focusing mirror and the beam splitter cannot be guaranteed accurately, which can easily lead to a relatively large indexing angle error between multiple focusing mirrors, and the indexing plane on the beam splitter The angle accuracy and position accuracy between the focusing surface and the focusing surface cannot meet the design requirements, and eventually the focus of the beam formed by multiple focusing mirrors cannot be converged to one point, and the molten material cannot be surrounded by a uniform beam, which cannot guarantee high-precision laser cladding work. expand
