[0002] Steam turbine stator blades are important components of steam turbines. The quality of their surface coating directly affects the performance and service life of steam turbines. Coating spraying is a commonly used surface treatment method that can improve the wear resistance, corrosion resistance and adhesion of blades. In order to achieve high-quality spray coverage of the surface coating of the stator blades, it is necessary to design a special tooling to fix and support the stator blades. Traditional coating spraying tooling has some problems, such as unstable fixation, inconvenient adjustment, low spraying accuracy, etc. For example, China has disclosed "a coating spraying covering tooling for steam turbine stator blades", and its application number is: "CN202120809269.X".
