Problems solved by technology

[0003] Existing laser cladding is mainly used for the cladding of the outer surface of the workpiece. Due to the small cladding space in the inner hole of the workpiece, the high temperature generated during the cladding process makes the lens and the powder feeding head easily damaged. Therefore, it needs to be improved to achieve a good cladding effect

Abstract

The invention discloses a high-speed laser inner hole cladding gun. The gun comprises a main body; the main body comprises a base with an optical fiber connector, a collimating mirror and a focusing mirror, a cladding head middle section, and a machining head section with a refractor frame and a protective mirror; a laser powder feeding head is arranged below the protective mirror; a focusing device is arranged between the collimating mirror and the focusing mirror; the middle section comprises a connecting rod; the connecting rod is connected with the focusing device and the refractor frame;a powder feeding channel, a cooling water channel and a protective gas channel are arranged inside the connecting rod; the powder feeding channel, the cooling water channel and the protective gas channel are communicated with the laser powder feeding head; the base is correspondingly provided with the powder feeding channel, the cooling water channel, an input interface of the protective gas channel and an output interface of the cooling water channel; and the cooling water channel forms a circulating cooling channel in the base, the connecting rod and the machining head section. The providedhigh-speed laser inner hole cladding gun can perform laser cladding on an inner hole of a workpiece and can continuously work for a long time.

Description

technical field [0001] The invention relates to the technical field of laser cladding, in particular to a high-speed laser inner hole cladding gun. Background technique [0002] High-speed laser cladding technology uses the method of synchronous powder feeding and material addition, using high-energy-density beams to simultaneously melt the added material and the surface of the substrate material moving at a high speed, and form a metallurgical bond with the substrate after rapid solidification. The cladding layer can greatly increase the cladding rate and significantly improve the process characteristics of the surface of the base material such as wear resistance, corrosion resistance, heat resistance, and oxidation resistance. [0003] Existing laser cladding is mainly used for the cladding of the outer surface of the workpiece. Due to the small cladding space in the inner hole of the workpiece, the high temperature generated during the cladding process makes the lens and ...
