Abstract

The invention discloses a pneumatic inward-clamped aero-engine rotor assembly method and device based on capacitance sensing measurement and belongs to the mechanical assembly technology. According to a measuring method and device, rotation standards are determined based on an air flotation rotating shaft system; angle positioning of a rotary table is determined according to an inductosyn; based on the four-measuring-head measuring device, the radial error of the radial assembly faces of rotors and the tilt error of the axial assembly faces of the rotors are extracted, and the influence weights of the rotors on the coaxiality obtained after assembly of the rotors are obtained; all the rotors needed during assembly are measured respectively, and the influence weights of the rotors on the coaxiality obtained after assembly of the rotors are obtained; vector optimization is conducted on the weights of the rotors, and the assembly angles of the rotors are obtained. The pneumatic inward-clamped aero-engine rotor assembly method and device based on capacitance sensing measurement can effectively solve the problem that the coaxiality obtained after assembly of the aero-engine rotors is low, and have the advantages that the coaxiality obtained after assembly of the aero-engine rotors is high, vibration is reduced, installation is easy, the flexibility ratio is high, and engine performance is improved.

Description

technical field [0001] The invention belongs to mechanical assembly technology, and mainly relates to an assembly method and device for an aero-engine rotor of an aerodynamic internal clamping type based on capacitive sensing measurement. 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 stabi...
