Assembly method and device for aero-engine rotors based on vector stacking principle

Abstract

The invention discloses an assembly method and device for aero-engine rotors based on a vector stacking principle and belongs to a mechanical assembly technology. A measuring method and device are based on a gas-magnetic combination rotating shaft system to determine rotating datum; based on an induction synchronizer, the angle positioning of a rotary table is determined; based on a four-measuring-head measuring device, the radial error of the radial assembly face of one rotor and the tilt error of the axial assembly face of one rotor are extracted, so that the weight value of influence, on coaxiality of next rotor assembly, of the rotor is obtained; all the rotors needed for assembly are respectively measured, so that the weight value of influence, on coaxiality of the next rotor assembly, of each rotor is obtained; vector optimization is performed on the weight values of all the rotors, so that assembly angles of all the rotors are obtained. The problem that the coaxiality is low after the aero-engine rotors are assembled can be effectively solved. The stacking assembly device has the advantages of being high in coaxiality after rotor assembly, reduces vibration, easy to install and high in flexibility and improving engine performance.

Description

technical field [0001] The invention belongs to mechanical assembly technology, and mainly relates to an aero-engine rotor assembly method and device based on the principle of vector stacking. 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 te...
