Problems solved by technology

[0002] After processing large and complex rotor blades, in order to ensure the surface roughness requirements, it is necessary to go through a smoothing process. The existing process uses manual polishing. However, large blades are difficult to operate manually and are affected by human factors. The consistency of processing quality and The stability is poor, and the more serious problem is that it is not suitable to ensure the geometric accuracy of the blade inlet and outlet edges, thus affecting the performance of the parts

Abstract

The invention discloses a horizontal composite vibration finishing device and method for large complex-structure rotor blades, and belongs to the technical field of aero-engine compressor blade surface finishing. The device comprises a vibration finishing mechanism and a clamp; the vibration finishing mechanism comprises a groove type container, and the groove type container is connected with a base through a plurality of spiral springs; vibration exciters are symmetrically arranged outside the groove type container, and a grinding medium is arranged in the groove type container and used forgrinding a rotor blade; the clamp is arranged in the groove type container and used for clamping the rotor blade; the clamp comprises a top base, a root base and a corresponding clamping mechanism, and the top base and the root base are connected through a plurality of protection columns. According to the horizontal composite vibration finishing device and method for the large complex-structure rotor blades, a traditional manual polishing mode can be replaced, automatic and refined manufacturing of the blade is achieved, and the surface integrity and the working reliability of parts are improved.

Description

technical field [0001] The invention relates to the technical field of surface finishing of aero-engine compressor blades, in particular to a horizontal composite vibration finishing device and method for a rotor blade with a large complex structure. Background technique [0002] After processing large and complex rotor blades, in order to ensure the surface roughness requirements, it is necessary to go through a smoothing process. The existing process uses manual polishing. However, large blades are difficult to operate manually and are affected by human factors. The consistency of processing quality and The stability is poor, and the more serious problem is that it is not suitable to ensure the geometric accuracy of the inlet and outlet edges of the blades, thereby affecting the performance of the parts. Contents of the invention [0003] In order to solve the technical problems existing in the prior art, the present invention provides a large complex structure rotor bla...
