Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of auxiliary tooling, and particularly to a lightweight pipe fitting spraying tooling with angle adjustment. Background Art
[0002] When processing high-strength lightweight pipe fittings, it is necessary to spray the surface layer of the high-strength lightweight pipe fittings so that the surface of the high-strength lightweight pipe fittings has properties such as wear resistance, corrosion resistance, high-temperature oxidation resistance, electrical insulation, heat insulation, radiation protection, friction reduction, and sealing. When spraying the surface layer of the high-strength lightweight pipe fittings, it is necessary to use tooling for auxiliary fixation.

Therefore, it cannot be converted according to the requirements of spraying the inner and outer surface layers of lightweight pipe fittings. It is necessary to separately equip two sets of tooling to achieve the spraying operation of the inner and outer surface layers, which requires a relatively high cost, and can only spray at a single angle, so there are limitations in use.
