Embodiment Construction

[0031] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Laser cladding is a new type of surface modification technology that uses laser beams to heat the surface of cladding materials and substrates, so that the required special materials are welded to the surface of the workpiece. Laser inner hole cladding equipment is used for laser cladding processing of the inner hole surface of parts with large and deep inner holes such as cylinder blocks, hydraulic columns, and sleeve parts.

[0033] Such as Figure 1 to Figure 6 As shown, the laser inner hole cladding equipment includes an optical fiber head 1, a rear-end lens group 3, an intermediate connector 4, a front-end lens group 5, and a powder feeding assembly on the side of the front-end lens group 5; the powder feeding assembly includes a gravity The powder feeder 6 and the powder feeding nozzle 7, the gravity powde...

Abstract

The invention relates to laser inner hole cladding equipment and a gravity powder feeder. According to the laser inner hole cladding equipment and the gravity powder feeder, the problems that in the case of existing laser inner hole cladding equipment, the powder feeding process is not uniform, the powder feeding stability is relatively poor, and the residual dust influences the laser light path and the cladding effect are solved. The laser inner hole cladding equipment comprises an optical fiber head, a rear-end lens set, an intermediate connecting piece, a front-end lens set and a powder feeding assembly arranged on one side of the front-end lens set, wherein the optical fiber head, the rear-end lens set, the intermediate connecting piece, the front-end lens set and the powder feeding assembly are sequentially arranged, the front-end lens set comprises a front-end lens and a front-end lens shell, the powder feeding assembly comprises the gravity powder feeder and a powder feeding nozzle, powder is fed into the powder feeding nozzle through the gravity powder feeder, the gravity powder feeder comprises a powder feeder shell, a driving device and a screw rod, the screw rod is arranged in the powder feeder shell, and is driven by the driving device, and a feeding hole and a discharging hole are formed in the powder feeder shell.

Description

technical field [0001] The invention relates to a laser processing device, in particular to a laser inner hole cladding equipment and a gravity powder feeder. Background technique [0002] Laser cladding refers to placing the selected coating material on the surface of the cladding substrate in different ways of adding materials. After laser irradiation and the thin layer on the surface of the substrate, it melts at the same time, and after rapid solidification, it forms a metallurgical coating with extremely low dilution and a metallurgical effect with the substrate. Combined surface coating, which significantly improves the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical properties of the base surface, so as to achieve the purpose of substrate surface modification or repair, which not only meets the specific performance requirements of the material surface Requirements, but also save a lot of precious elements. [0003] As the k...
