Problems solved by technology

However, the shortcoming of this prior art is that the mechanism can only realize three degrees of freedom of one movement and two rotations, which cannot meet the requirements of five degrees of freedom for vertical assembly of high-pressure rotors of large aero-engines, and cannot be applied to vertical high-pressure rotors. Intelligent assembly

Abstract

The invention relates to the field of engines and provides an intelligent high-pressure rotor assembly device with an elastic structure for an aeroengine. The intelligent high-pressure rotor assembly device comprises a three-DOF (Degrees of Freedom) gantry-type active movement mechanism which is used for realizing spatial X-axis, Y-axis and Z-axis translation, a five-DOF parallel-type passive movement mechanism which is used for realizing spatial X-axis and Y-axis translation and rotation around the X axis, the Y axis and the Z axis, and a rotor fixture, wherein the five-DOF parallel-type passive movement mechanism is slidably arranged on the three-DOF gantry-type active movement mechanism; the rotor fixture is fixedly arranged on a movable platform of the five-DOF parallel-type passive movement mechanism; the spatial posture of a to-be-assembled rotor is regulated by virtue of the three-DOF gantry-type active movement mechanism and the five-DOF parallel-type passive movement mechanism, so that assembly is realized. By virtue of the vertical intelligent high-pressure rotor assembly device, the engine production efficiency and the engine assembly quality can be improved.

Description

technical field [0001] The invention relates to a device in the field of engines, in particular to an intelligent high-pressure rotor assembly equipment of an aero-engine with an elastic structure. Background technique [0002] At present, in the assembly process of large-scale aero-engine high-pressure rotors in my country, the attitude adjustment and positioning of the rotors are still done manually with the help of cranes, which is easy to cause bumps and jams, and the efficiency is low. The operating experience of workers is the key factor affecting the assembly quality. With the research and development of high-performance engines, the precision requirements for connection and coordination are getting higher and higher, and manual assembly can no longer meet the requirements. In view of this major problem, a set of intelligent assembly equipment has been developed to complete the assembly task of the high-pressure rotor of the engine. Improve assembly quality while impr...
