Thin-wall ring spray protection tool

Abstract

The invention relates to a thin-wall ring spray protection tool. The thin-wall ring spray protection tool comprises a positioning ring, a bearing plate, and a spindle; the positioning ring comprises a fixed half ring and a moving half ring which are mounted on the bearing plate through flange edges; a plurality of semicircular boss structures are arranged in two half rings; the space between two adjacent bosses is equal to the width of a member to be sprayed; ventilating slots are formed in the two half rings; and the spindle is positioned on the axis of the positioning ring and is fixedly connected with the positioning ring. In the structure design of the tool, the assembly, adjustment, cleaning and other factors are fully considered, coating adhesion difficulty of the components are effectively solved, and the coating quality is improved; and the thin-wall ring spray protection tool has the advantages that the components are flexible in assembly, clamping and disassembly processes after spraying of the components are simple and convenient to operate, the tool is easy to clean, and the service life of the tool is prolonged.

Description

technical field [0001] The invention relates to a thin-walled ring spray protection tool, which is mainly used for the same batch of spray coating on the inner wall of the same-level or multi-level thin-walled ring with the same outer diameter, and plays the roles of positioning, clamping and protecting the sprayed parts. Background technique [0002] In the field of aviation, aeroengines are designed with several stages of rotors, some of which need to be sprayed with nickel-graphite sealing coating on the inner wall of the outer ring. When spraying, if you spray one piece at a time, it will affect the production progress and waste the sprayed paint. Therefore, it is considered to spray multiple pieces at a time. At present, the structure of the tooling that sprays multiple pieces at a time is as follows: figure 1 Shown: The cylindrical positioning ring is used for positioning, 5 pieces are sprayed each time, the parts are clamped in the positioning ring in an adjacent arra...

AI Technical Summary

Problems solved by technology

As a result, during the disassembly and disassembly process of the parts after spraying, it was found that fibroids appeared on the surface of the coating due to spraying dust and poor air circulation; the parts were covered and bonded together by spraying paint

When the external force is used to decompose, the coating between adjacent parts will crack, and the coating on the inner wall of the part will fall off, resulting in the unqualified spray coating of the parts.
