Hydraulic pressure based on inductosyn grabs cassette aeroengine rotor assembly apparatus

Hydraulic pressure based on inductosyn grabs cassette aeroengine rotor assembly method and device belongs to mechanical assembly technique.Its method of measurement and device are based on air supporting rotary axis system determination rotative benchmark; According to the angular positioning of inductosyn determination turntable; Based on four gauge head measuring devices, extract the radial error of rotor radial mating face and the tilt error of axial mating face, obtaining this rotor affects weights to rotor coaxial degree after assembling; Respectively measure assembling needed for whole rotors, obtain each rotor on assembling after rotor coaxial degree affect weights; The weights of each rotor are carried out vector optimization, obtains the angle of assembling of each rotor.The present invention effectively can solve the low problem of coaxality after aeroengine rotor assembling, after there is rotor assembling coaxality high, reduce vibration, be easy to install, flexibility ratio is high, the feature of improving engine performance.
