Integrated laser cladding head

Abstract

The invention is an integrated laser cladding head, which includes a cladding head body, a laser channel is opened in the center of the cladding head body for the laser to pass through, a focusing device is arranged on the upper part of the cladding head body, and the focusing device It includes a conversion frame, three lenses of different specifications, a rotating shaft and a knob. The lens is embedded in the three rings of the conversion frame. The knob is connected to the conversion frame through a rotating shaft. The laser is focused through the lens. A cooling water channel is provided, and the cooling water channel surrounds the laser channel in a spiral shape. Four powder channels are uniformly distributed on the outside of the cooling water channel, and four protective gas channels are uniformly distributed on the outside of the powder channel. The focusing device of the present invention Contains three lenses of different specifications, which can be switched freely to change the shape of the spot. There is a spiral cooling water channel outside the laser channel. The cladding head is not easy to overheat. There are four powder channels evenly distributed in the axial direction outside the cooling channel, which is not easy to block and sprays powder smoothly.

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.
