Assembly method and device.
Background technology
Aero-engine assembling is the final tache in aero-engine manufacture process, is also of paramount importance system
Make one of link.Under existing Aeroengine Design scheme and process technology level conditions, the matter of assembling
Amount and operating efficiency have material impact for the quality of engine, performance and production efficiency.So in assembling
During to improve the axiality of rotor after installation as far as possible, and then reduce the vibration of aero-engine, change
The performance of kind aero-engine.But, in reality produces, the assembling of aero-engine is complete hand assembled,
The height of assembly precision and operating experience and the technical merit of whether stablizing the assembler that places one's entire reliance upon, lack
A kind of high speed effectively instructs the method that aeroengine rotor assembles, and then improves efficiency of assembling, reduces boat
Empty engine luggine, improves the performance of aero-engine.
As aero-engine assembling measuring technology increasingly comes into one's own, aero-engine assembles measuring technology
Increasingly come into one's own, and become the focus of research.Increasing researcher is for aero-engine
Rotor has carried out deep discussion, and Rools-Royce proposes a kind of scheme (System and method for
improving the damage tolerance of a rotor assembly.European Patent Publication No:
EP2525049A2), mainly by each sub-test system is obtained the stress signal of rotor each position, main system
The signal of each subsystem collection is analyzed, damages the impact on assembling for the Parameter analysis from the appearance of each rotor, enter
And improve the assembling of aeroengine rotor.The method there is a problem in that does not analyzes rotor
The impact on assembling for the geometric sense aspect, it is impossible to improve the impact on assembling for the geometric sense.
Xi'an Communications University proposes a kind of method for testing assembly performance of rotor of aircraft engine (a kind of aeroplane engine
Machine rotor assembly performance detection method.Publication number: CN101799354A).The method is initially with vibrator
Exciting aeroengine rotor, utilizes vibrating sensor and signal acquiring system software to obtain a multicarrier coupling
The impulse response signal of the aeroengine rotor closing；Then the aviation to the multicarrier coupling being obtained

Under conditions of, final inspection is by installing the Determines after coordinating, and the index of evaluation is mainly rotor after assembling
Axiality parameter.Engine rotation produces high pressure, and its rotor is by multiple single part groups combined
Become, ideal when the gyroaxis of each parts and the dead in line of whole engine.High-performance enginer work
High Rotation Speed speed when making is more than 10000rpm, and single part axially or radially beat will necessarily cause the turbine disk
Engine rotation axis is deviateed at center, can produce very big centrifugal force in such a situa-tion, cause rotor
The imbalance rotating, causes engine luggine, hereby it is ensured that the axiality after the assembling of each parts is the weight installed
Point and difficult point.
One Model Mounting not using axiality optimization method, all parts axially and radially due to processing
Precision restriction existence is beated, eccentric, inclination equal error.If directly assembled randomly, it is possible to shape
Become to be similar to the bending situation of " banana ", i.e. upper component have accumulated bias or the inclination of following all parts
Error, beat overall after causing assembling is huge with inclination, causes engine rotor axiality excessively poor, difficult
Require in satisfied use.
At present, domestic engine assembly still uses traditional assembly method, tests manually with amesdial
Based on.According to assembled in sequence engine from top to bottom, measure after assembling parts, it is ensured that every
Entirety after secondary increase parts disclosure satisfy that the threshold condition of axiality, then upwards installs another parts again.
Every time using previous parts as benchmark, the final axiality requiring entirety is within the specific limits.This side
Method takes a substantial amount of time, and the possibility done over again is big, affects very much efficiency and the one-time success rate of installation,
Generally once successfully assembling needs 4 to 5 days.And, because not being optimum assembling position, it usually needs
Dismounting 4 to 5 times, in addition it is also necessary to workman assembles with rich experiences, assembling every time is required for experiencing hot-working
And cold working.It so current aerospace engine assembly method installation effectiveness is low, is difficult to install, and after assembling
Axiality difference, affects engine performance.
