The invention discloses a blade crown spraying protection fixture of a turbine blade and a blade crown spraying method of a turbine blade, comprising a frame, a first clamping mechanism and a second clamping mechanism arranged on the outer wall surface of the frame, the first The clamping mechanism and the second clamping mechanism are arranged oppositely along the height direction of the frame. The first clamping mechanism is used to resist the upper surface of the blade crown and protect the upper surface of the blade crown during the spraying operation. The second clamping mechanism The upper surface of the holding mechanism is concavely provided with a positioning groove arranged obliquely relative to the frame in the horizontal direction. The bottom surfaces are abutted, and the first clamping mechanism and the second clamping mechanism jointly clamp and fix the turbine blade to be processed so that the blade shroud is arranged in the horizontal direction. The blade crown spraying protection fixture of the turbine blade of the present invention only needs to move the spray gun back and forth for spraying during the spraying operation, which is beneficial to control the spraying quality of the blade crown.
Description
technical field [0001] The invention relates to the technical field of spray protection of aviation turbine blades, in particular to a blade crown spray protection fixture of a turbine blade. In addition, the present invention also relates to a method for spraying the shroud of a turbine blade. Background technique [0002] Turbine working blades are important parts of power machinery such as aero-engines, steam turbines, and gas turbines. They are combined into a whole plate and assembled on the turbine part of the engine. Its substrate is often made of high-temperature materials and needs to work in extreme environments of high temperature and high pressure. Under normal circumstances, in order to ensure long-term reliable operation of turbine blades, it is necessary to spray wear-resistant coatings on the shroud mating surface of each turbine blade to achieve fretting wear resistance and prolong the service life of the blades. [0003] Such as figure 1 As shown, the tu...
