[0002] Stator blades, also known as fixed blades, are the general term for the blades installed on the cylinder and diaphragm; their main function is to affect the flow of air by changing the direction of the air flow, thus playing a key role in the operation of engines or compressors; specifically, the functions of stator blades include: rectifying function: in an aeroengine, the stator blades are located in the outer bypass duct, rectifying the air flow after the fan, optimizing the air flow, reducing turbulence and eddies, and improving the engine efficiency; noise reduction: by optimizing the sweep of the fan stator blades, the fan rotor-stator interference noise can be reduced, and the noise performance of the engine can be improved; efficiency improvement: in an axial compressor, the design and optimization of the stator blades can reduce the leakage loss and the radial clearance with the rotor, thus improving the efficiency of the compressor.

[0003] In an aeroengine, the blades of the engine are the most important components. The existing aeroengine blades and the impeller of the engine are mainly connected by a tenon and mortise structure. Therefore, the root of the aeroengine blade is usually designed as a tenon type. Due to the irregular structure of the tenon, during the processing, the root of the tenon blade is mostly clamped by rigidly fixing the two side planes of the tenon. However, it is very difficult to achieve clamping and positioning for the circular outer shape structure of the stator blade during processing, resulting in time-consuming and laborious processing and great operation difficulty. In view of this, the utility model provides a universal tenon clamp for stator blades used in wire cutting. Summary of the Utility Model
