Description

Technical field [0001] The invention belongs to mechanical assembly technology, and mainly relates to a method and device for assembling a hydraulic gripping aeroengine rotor based on inductive sensing. Background technique [0002] Aeroengine assembly is the last link in the manufacturing process of aeroengines and one of the most important manufacturing links. Under the existing aeroengine design scheme and processing technology level, the quality of assembly and work efficiency have an important influence on the quality, performance and production efficiency of the engine. Therefore, in the assembly process, the coaxiality of the rotor after installation should be improved as much as possible, thereby reducing the vibration of the aero-engine and improving the performance of the aero-engine. However, in actual production, the assembly of aeroengines is completely manual. The accuracy and stability of the assembly are completely dependent on the operating experience and techni...
