Embodiment Construction

[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 hydraulic gripping aeroengine rotor based on inductive sensing. The method and device are as follows: a three-jaw hydraulic chuck 4 is arranged on a center position of a centering and tilting workbench 3. The door-shaped left column 5a and the door-shaped right column 5b are symmetrically distributed on both sides of the air bearing shaft system 2 and fixed on the base 1. The two ends of the door-shaped beam 5c are connected with the upper end of the door-shaped left column 5a and the door-shaped right column 5b. The upper end is firmly connected. On the door-shaped left column 5a, the left upper column connecting piece 7c and the left lower column connecting piece 7a are movably and adjustablely fitted from top to bottom. The left upper horizontal measuring rod 6c is horizontally nested on the left upper column connec...

Abstract

The invention relates to a hydraulic capturing and clamping type aircraft engine rotor assembling method and device based on inductance sensing, and belongs to the machine assembling technology. According to the hydraulic capturing and clamping type aircraft engine rotor assembling method and device, a rotation standard is determined based on an air floating rotation shaft system; angle location of a rotary table is determined according to an inductive synchronizer; based on a four-measuring-head measuring device, radial errors of a rotor radial assembly face and slant errors of an axial assembly face are extracted, and the influence weights of rotors on the rotor coaxiality after the rotors are assembled are obtained; all the rotors required to be assembled are respectively measured, and the influence weights of the rotors on the rotor coaxiality after the rotors are assembled are obtained; vector optimizing is carried out on the weights of the rotors, and the assembling angles of the rotors are obtained. According to the hydraulic capturing and clamping type aircraft engine rotor assembling method and device, the problem that the coaxiality is low after the aircraft engine rotors are assembled is solved, and after the rotors are assembled, the hydraulic capturing and clamping type aircraft engine rotor assembling method and device have the advantages of being high in coaxiality, reducing vibration, being easy to install and high in flexibility, and improving the engine performance.

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...
