Problems solved by technology
Due to the complex tenon structure and narrow area, it is difficult to protect the non-sprayed area. The existing methods not only cannot guarantee the consistency of the sprayed area, but also the tape needs to be trimmed later, which will lead to defects such as scratches on the tenon, which will cause serious damage to the blade installation and use. Hidden danger

Abstract
The invention discloses a spraying protection clamp for a blade tenon and a manufacturing method thereof. The spraying protection clamp for the blade tenon comprises a support plate and a pressing plate, the support plate comprises a support plate chuck and a support plate pressing handle, and the support plate chuck is fixedly connected with the support plate pressing handle; the pressing plate comprises a pressing plate chuck and a pressing plate pressing handle, and the pressing plate chuck is fixedly connected with the pressing plate pressing handle, wherein the support plate pressing handle is hinged with the pressing plate pressing handle by a joint shaft to form a hairpin structure; a spring is installed on the joint shaft, and the spring is used for realizing that the spraying protection clamp for the blade tenon is in a clamping state when no external force is applied; spraying windows are processed on the support plate chuck and the pressing plate chuck to spray coatings on aworking surface of the blade tenon; and when the spraying protection clamp for the blade tenon is clamped at the blade tenon, the inner side walls of the support plate chuck and the pressing plate chuck are respectively attached to the blade tenon. The spraying protection clamp for the blade tenon provided by the invention can protect the non-spraying area of the blade tenon during a thermal spraying process, and the consistency of the coating quality of the working surface of the tenon can be improved.
Description
technical field [0001] The invention belongs to the technical field of aero-engines, and relates to a blade tenon tooling fixture, in particular to a blade tenon spraying protection fixture and a manufacturing method thereof. Background technique [0002] With the development of aero-engine technology, the requirements for the service life of the engine are getting higher and higher. As the core part of the engine, the compressor blade has increasingly high requirements on the anti-corrosion performance of its surface. In order to reduce the blade replacement rate and prolong its service life, it is often necessary to spray a lubricating and wear-resistant coating on the tenon working surface, while the non-working surface does not need to be sprayed, that is, it needs to be protected during spraying. [0003] At present, the existing protection method is usually manual protection with high temperature resistant adhesive tape. Due to the complex tenon structure and narrow ...
