Problems solved by technology

[0003] The present invention can only realize the movement of three degrees of freedom of one movement and two rotations of the existing device, which cannot meet the requirements of five degrees of freedom for vertical assembly of high-pressure rotors of large aeroengines, and cannot be applied to vertical intelligent assembly of high-pressure rotors and unsatisfactory It has the defects of large-scale precision attitude adjustment function and insufficient attitude adjustment accuracy. A vertical assembly equipment for the assembly of component holes and shafts is proposed to complete the assembly of aero-engines. The device has compact structure, hierarchical control, high operation accuracy, and six freedoms. Accurate attitude adjustment, high assembly efficiency, and ensure the passive safety of the parts to be assembled

Abstract

The invention discloses vertical-type assembling equipment for part hole and shaft assembling. The vertical-type assembling equipment comprises a passive compliance device which is arranged on a vertical wide-range feeding mechanism and used for guaranteeing passive safety, and a six-degrees-of-freedom precision posture-adjusting mechanism which is arranged on a horizontal wide-range feeding mechanism and used for achieving the precision posture-adjusting function. A to-be-assembled hole part is arranged on the passive compliance device and directly faces a to-be-assembled shaft part arranged on the six-degrees-of-freedom precision posture-adjusting mechanism. The vertical-type assembling equipment is used for completing aero-engine assembly. The device is compact in structure, capable of achieving stepped control, high in operation precision, high in assembling efficiency, and capable of achieving six-degrees-of-freedom posture adjustment and guaranteeing the passive safety of the to-be-assembled parts.

Description

technical field [0001] The invention relates to equipment in the technical field of assembly, in particular to a vertical assembly equipment for precise assembly of holes and shafts between components. Background technique [0002] At present, in the assembly process of low-pressure turbine rotors of large turbofan engines and other large components in China, a large number of assembly processes are still completed 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 to the quality of assembly. factor. With the research and development of high-performance engines, the requirements for connection and matching precision are getting higher and higher, and manual assembly can no longer meet the requirements. In response to this major problem, a set of intelligent assembly equipment was developed to complete the assembly of the high-pressure rotor of the engine, improve the assembly acc...
