The invention discloses a method and a device for assembling an aero-engine rotor based on eddy current sensing and pneumatic catching, which belong to the field of mechanical assembly technologies. According to the measurement method and device, a rotating reference is determined based on an air floatation rotating axis system; the angle location of a rotating table is determined by an inductosyn; the radial error of a radial assembly surface and the tilt error of an axial assembly surface of the rotor are extracted to obtain the influence weight of the rotor on the coaxiality of the rotor after assembly based on a measurement devices with four measurement heads; all the rotors needed by assembly are measured to obtain the influence weights of the rotors on the coaxiality of the rotors after assembly; vector optimization is carried out on the weights of the rotors to obtain the assembly angles of the rotors. According to the method and the device disclosed by the invention, the problem of low coaxiality after the assembly of the aero-engine rotor can be effectively solved; and the method and the device have the characteristics of being high in coaxiality after the assembly of the rotor, capable of reducing vibration, easy to install, high in flexibility and capable of improving engine performance.
Description
technical field [0001] The invention belongs to mechanical assembly technology, and mainly relates to an aeroengine rotor assembly method and device based on eddy current sensing and pneumatic gripping. 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 experie...
