Abstract

The invention discloses a magnetically-levitated aero-engine rotor assembly method and device based on orthogonality measurement and belongs to the field of machine assembly technologies. According to the measuring method and device, a rotation datum is determined based on a magnetically-levitated rotating shaft system; angle location of a rotary table is determined based on an optical-electricity encoder; radial errors of a radial rotor assembly face and heeling errors of an axial rotor assembly face are extracted based on the four-measuring-head measuring device to obtain the weight of the influence of the current rotor on rotor coaxiality after assembly is completed; all rotors needed for assembly are respectively measured to obtain the weight of the influence of each rotor on rotor coaxiality after assembly is completed; vector optimization is carried out on the influence weight of each rotor to obtain the assembly angle of the corresponding rotor. The method can effectively solve the problem of low coaxiality after aero-engine rotor assembly, and has the advantages that the coaxiality is high after rotor assembly, vibration 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 a method and device for assembling a maglev aeroengine rotor based on orthogonal measurement. Background technique [0002] Aeroengine assembly is the last link in the manufacturing process of aeroengines and one of the most important manufacturing links. Under the existing aeroengine design scheme and processing technology level, the quality of assembly and work efficiency have an important influence on the quality, performance and production efficiency of the engine. Therefore, in the assembly process, the coaxiality of the rotor after installation should be improved as much as possible, thereby reducing the vibration of the aero-engine and improving the performance of the aero-engine. However, in actual production, the assembly of aeroengines is completely manual. The accuracy and stability of the assembly are completely dependent on the operating experience and technical lev...
