[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings:

[0021] A method and device for assembling a rotor of a hydraulic gripping aero-engine based on an induction synchronizer. The method and device are as follows: a three-jaw hydraulic chuck 4 is arranged on a center position of a centering and tilting table 3. The left motion guide rail 11a and the right motion guide rail 11b are symmetrically distributed on the base 1 on both sides of the air bearing system 2; the left column 5a is mounted on the left motion rail 11a, and the right column 5b is mounted on the right motion rail 11b. On the left column 5a, the left upper column connecting piece 7c and the left lower column connecting piece 7a are movably and adjusted from top to bottom. The left upper horizontal measuring rod 6c is horizontally nested on the left upper column connecting piece 7c, and the upper sensor is transferred The piece 10b is fixedly connecte...

Abstract

The invention discloses a hydraulic grasping clamping type aircraft engine rotor assembly method and device based on an inductosyn, and belongs to the mechanical assembly technology. According to the hydraulic grasping clamping type aircraft engine rotor assembly method and device based on the inductosyn, the rotation reference is determined on the basis of an air floating rotation shaft system; angle locating of a rotary table is determined according to the inductosyn; the radial error of the radial assembly face and the inclination error of the axial assembly face of one rotor are extracted on the basis of a four-measuring-head measuring device, so that the weight of influence caused by the rotor on coaxiality of the assembled rotor is obtained; all rotors needed by assembly are measured to obtain the weight of influence caused by the rotors on the coaxiality of the assembled rotors; vector optimization is carried out on the weight of the rotors to obtain the assembly angles of the rotors. The hydraulic grasping clamping type aircraft engine rotor assembly method and device based on the inductosyn can effectively solve the problem that coaxiality is low after rotors of an aircraft engine are assembled, and have the advantages that coaxiality of the assembled rotors is high, the magnitude of vibration is reduced, installation is easy, flexibility is high, and engine performance is improved.

Description

technical field [0001] The invention belongs to the mechanical assembly technology, and mainly relates to a method and device for assembling a rotor of a hydraulic grab type aero-engine based on an induction synchronizer. 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 enti...
