Abstract

The invention discloses an aero-engine rotor stack-assembling method and device and belongs to the technical field of mechanical assembly. The method comprises the steps of determining a rotary standard based on an air floatation rotary shaft system, determining angle location of a rotary table through an optical-electricity encoder, extracting the radial error of a rotor radial assembly surface and the oblique error of a rotor axial assembly surface through a four-measuring-head measurement device to obtain the influence weight of a rotor on the coaxiality of assembled rotors, measuring all the rotors needed by assembly to obtain the influence weight of each rotor on the coaxiality of the assembled rotors, and conducting vector optimization on the weight of each rotor to obtain the assembly angle of each rotor. The method and device can effectively solve the problem that coaxiality of aero-engine rotors is low after assembly and has the advantages that coaxiality of the rotors is high after assembly, vibration is reduced, installation is easy to achieve, flexibility is high, and the performance of an engine is improved.

Description

technical field [0001] The invention belongs to mechanical assembly technology, and mainly relates to an aeroengine rotor stacking assembly method and 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 assemblers. T...
