Abstract

The invention relates to an aircraft engine rotor assembling method and device based on air/magnetism mixing guiding, and belongs to the machine assembling technology. According to the aircraft engine rotor assembling method and device, a rotation standard is determined based on an air and magnetism combined rotation shaft system; angle location of a rotary table is determined according to an optical-electricity encoder; based on a four-measuring-head measuring device, radial errors of a rotor radial assembly face and slant errors of an axial assembly face are extracted, and the influence weights of rotors on the rotor coaxiality after the rotors are assembled are obtained; all the rotors required to be assembled are respectively measured, and the influence weights of the rotors on the rotor coaxiality after the rotors are assembled are obtained; vector optimizing is carried out on the weights of the rotors, and the assembling angles of the rotors are obtained. According to the aircraft engine rotor assembling method and device, the problem that the coaxiality is low after the aircraft engine rotors are assembled is solved, and after the rotors are assembled, the aircraft engine rotor assembling method and device have the advantages of being high in coaxiality, reducing vibration, being easy to install and high in flexibility, and improving the engine performance.

Description

technical field [0001] The invention belongs to mechanical assembly technology, and mainly relates to an aeroengine rotor assembly method and device based on gas / magnetic hybrid guidance. 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 technic...
