Integrated laser cladding head

Abstract

The invention discloses an integrated laser cladding head. The integrated laser cladding head comprises a cladding head body, wherein a laser channel for allowing laser to pass through is arranged in the center of the cladding head body; a focusing device is arranged at the upper part of the cladding head body; the focusing device comprises a converting frame, lenses with three different specifications, a rotating shaft and a rotary knob; the lenses are embedded in three circular rings of the converting frame; the rotary knob is connected with the rotating shaft through the converting frame; the laser is focused through the lenses; a cooling water channel is arranged outside the laser channel; the cooling water channel spirally surrounds the laser channel; four powder channels are uniformly distributed outside the cooling water channel in the axial direction; and four protective gas channels are uniformly distributed outside the powder channels in the axial direction. According to the integrated laser cladding head, the focusing device comprises the lenses with three different specifications, the lenses can be freely switched to change the laser spot shape, the spiral cooling water channel is arranged outside the laser channel, the cladding head is difficult to heat, the four powder channels are uniformly distributed outside the cooling water channel in the axial direction, the powder channels are not liable to block, and the powder spraying is smooth.

Description

technical field [0001] The invention relates to the technical field of laser cladding equipment, in particular to an integrated laser cladding head. Background technique [0002] Laser cladding technology refers to placing selected coating materials on the surface of the coated substrate with different filler methods, melting it and a thin layer of the substrate surface at the same time through laser irradiation, and forming a very low dilution and coating material after rapid solidification. A surface coating that forms a metallurgical combination with the base material, thereby significantly improving the wear resistance, corrosion resistance, heat resistance, oxidation resistance, and electrical properties of the base material surface. The laser cladding head is the final output part of the laser cladding device. The existing laser cladding head outputs a single-shaped laser spot. If you want to change the spot for production operations, you need to replace the entire las...

AI Technical Summary

Problems solved by technology

The laser cladding head is the final output part of the laser cladding device. The existing laser cladding head outputs a single-shaped laser spot. If you want to change the spot for production operations, you need to replace the entire laser system, which has a single function. , and most of them have problems such as easy blockage of powder spraying channels, low efficiency, and easy overheating of cladding heads.
