Abstract

Disclosed are a double-stand-column aero-engine rotor electric drive assembly method and device based on eddy current sensing. According to the assembly method and device, rotation reference is determined based on a magnetic levitation rotation shaft system, angle location of a rotary platform is determined through an inductosyn, the radial error of the radial assembly face and the inclination error of the axial assembly face of each rotor are extracted through a four-measuring-head measurement device, and the weight of influence on the coaxiality of the assembled rotors from the rotors is obtained; all the rotors needed by assembly are measured, and the weight of influence on the coaxiality of the assembled rotors from the rotors is obtained; vector optimization is carried out on the weight of each rotor, and then the assembly angle of each rotor is obtained. The double-stand-column aero-engine rotor electric drive assembly method and device based on eddy current sensing can effectively solve the problem of the low coaxiality after the aero-engine rotors are assembled, and have the advantages that the coaxiality achieved after the rotors are assembled is high, vibration is reduced, installation is easy, the flexibility is high, and performance of an engine is improved.

Description

technical field [0001] The invention belongs to mechanical assembly technology, and mainly relates to an electric drive assembly method and device for a double-column aeroengine rotor based on eddy current sensing. Background technique [0002] Aeroengine assembly is the last link in the manufacturing process of aeroengine, and it is also one of the most important manufacturing links. Under the conditions of the existing aero-engine design scheme and processing technology level, the quality of assembly and work efficiency have an important impact on the quality, performance and production efficiency of the engine. Therefore, in the assembly process, the coaxiality of the installed rotor should be improved as much as possible, so as to reduce the vibration of the aero-engine and improve the performance of the aero-engine. However, in actual production, the assembly of aero-engines is completely manual assembly. The level of assembly accuracy and stability depends entirely on...
