Abstract

The invention discloses a blade spraying protection fixture and a blade spraying protection method for fixedly clamping blades to be treated and protecting blade crown parts of the blades. The blade spraying protection fixture comprises a frame main body for fixedly clamping blade molded surfaces and spraying blade sprayed areas; the frame main body is provided with a slide block with a notch anda peripheral degree of freedom; the slide block is filled with plaster for protecting the blade crown parts of the blades; and the frame main body is provided with a pushing piece distributed oppositeto the slide block and used for matching with the slide block to axially clamp the blades. In the blade spraying protection fixture, the blades are clamped on the frame main body; the blade crown parts of the blades are pushed into the plaster in the slide block through the pushing piece; and the plaster is tightly attached on the blade crown parts of the blades for protection. The blade sprayingprotection fixture achieves effectively spraying protection on edge plates and comb teeth at the blade crown ends of turbine working blades, and improves the coating quality.

Description

technical field [0001] The invention relates to the field of spray protection of aviation turbine blades, in particular to a blade spray protection fixture. In addition, the present invention also relates to a blade spray protection method comprising the above-mentioned blade spray protection fixture. Background technique [0002] In the process of thermal spraying, the protection of parts before spraying and the cleaning after spraying are relatively important links, and they are also the most time-consuming and manpower-consuming links. For example, the working blade of a turbine of a certain type needs to be sprayed with a layer of wear-resistant coating on the blade crown, and the other parts of the blade should not have redundant objects during the spraying process and need to be protected. Due to the particularity of spraying, after spraying, the adjacent area of ​​the blade shroud will have some residual coating, so the adjacent area of ​​the blade shroud needs to be...
