The invention discloses a method and device for double-stand-column type aeroengine rotor assembly on the basis of inductosyn angle measurement, and belongs to the mechanical assembly technologies. According to the method and device, the rotation base is determined on the basis of a gas-and-magnetism combination rotary shaft system; angle location of a rotary platform is determined through an inductosyn; radial errors of a radial assembly surface and inclination errors of an axial assembly surface of each rotor are extracted on the basis of a measuring device with four measuring heads, and the weight of influence, caused by each rotor, on the coaxiality of the assembled corresponding rotor is obtained; all the rotors needing assembly are measured to obtain the weights of influence, caused by the rotors, on the coaxiality of the assembled corresponding rotors are obtained; vector optimization is carried out on the weights of the rotors to obtain assembly angles of the rotors. The method and device for double-stand-column type aeroengine rotor assembly on the basis of inductosyn angle measurement can effectively solve the problem that coaxiality of assembled aeroengine rotors is low, and have the advantages that the coaxiality of the assembled rotors is high, the vibration amplitude is reduced, installation is easy, flexibility is high, and engine performance is improved.

Description

technical field [0001] The invention belongs to mechanical assembly technology, and mainly relates to an assembly method and device for a double-column aeroengine rotor based on angle measurement by an induction synchronizer. 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 ...
