The invention relates to an assembling method and device for aero-engine rotors of a movable double-stand-column structure, and belongs to mechanical assembly technologies. A measuring method includes the steps that a slewing datum is determined based on a gas-magnetic combination; the angle location of a turntable is determined according to an optical-electricity encoder; the radial-direction error of the radial-direction assembling face and the inclination error of the axial assembling face of one rotor are extracted based on a four-measuring-head measuring device to obtain the influence weight on rotor coaxiality after assembly by the rotor; all the rotors needed by assembly are measured respectively to obtain the influence weights on rotor coaxiality after assembly by all the rotors; vector optimization is performed on the weights of all the rotors to obtain assembling angles of all the rotors. The assembling method and device can effectively solve the problem that the coaxiality is low after the aero-engine rotors are assembled and have the advantages that the coaxiality is high after the aero-engine rotors are assembled, vibration is reduced, the rotors are easy to install, flexibility is high, and performance of the engine is improved.
Description
technical field [0001] The invention belongs to mechanical assembly technology, and mainly relates to a movable double column structure aero-engine rotor assembly device. 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 the experience and technical level of the a...
