Stacking assembly method and device.
Background technology
Aero-engine assembling is the final tache in aero-engine manufacture process, is also of paramount importance manufacture link
One of.Under existing Aeroengine Design scheme and process technology level conditions, the quality of assembling and work efficiency for
The quality of electromotor, performance and production efficiency have material impact.So after improving installation as far as possible during assembling
The axiality of rotor, and then reduce the vibration of aero-engine, improve the performance of aero-engine.But, in reality produces
The assembling of aero-engine is complete hand assembled, the height of assembly precision and the behaviour whether stablizing the assembler that places one's entire reliance upon
Make experience and technical merit, lack a kind of method that high speed effectively instructs aeroengine rotor to assemble, and then improve assembling
Efficiency, reduces aeroplane engine machine vibration, improves the performance of aero-engine.
Along with aero-engine assembling measuring technology increasingly comes into one's own, aero-engine assembling measuring technology is increasingly
Come into one's own, and become the focus of research.Increasing research worker has carried out deep for aeroengine rotor
Discussing, Rools-Royce proposes a kind of scheme (System and method for improving the damage

Liming Aeroplane Engine (Group) Co., Ltd., Shenyang City proposes a kind of gap measuring method (engine rotor leaf
Point radial clearance contactless measurement.Publication number: CN102175135A).The method uses capacitance measurement technology, measures
Step is as follows, first assembling measurement system, calibration sensor, determines the relation between blade tip radial clearance and voltage, then will pass
Sensor is fixed on blade, finally measures engine rotor blade tip radial clearance.The method there is a problem in that and not account for
Axially mounted impact after rotor assembles during rotor assembling.
The test of aero-engine assembling, to liking stators and rotor, meets the condition of requirement in component processing precision
Under, final inspection by installing the Determines after coordinating, the axiality parameter of rotor after the mainly assembling of the index of evaluation.Start
Machine rotates and produces high pressure, and its rotor is made up of multiple single parts combined, the gyroaxis of each parts and whole
During the dead in line of motivation ideal.High speed rotating speed during high-performance enginer work is more than 10000rpm, single part
Axially or radially beat will necessarily cause turbine disk center to deviate engine rotation axis, can produce very in such a situa-tion
Big centrifugal force, causes the imbalance that rotor rotates, causes engine luggine, hereby it is ensured that the axiality after the assembling of each parts is
The emphasis installed and difficult point.
One Model Mounting not using axiality optimization method, axially and radially limiting due to machining accuracy of all parts
Existence processed is beated, eccentric, inclination equal error.If directly assembled randomly, it is possible to formed and be similar to the curved of " Fructus Musae "
Bent situation, i.e. upper component have accumulated bias or the heeling error of following all parts, beat overall after causing assembling and inclining
The hugest, cause engine rotor axiality excessively poor, it is difficult to meet and use requirement.
At present, domestic engine assembly still uses traditional assembly method, tests manually based on amesdial.Press
According to assembled in sequence electromotor from top to bottom, measure after assembling parts, it is ensured that increase the entirety after parts every time
Disclosure satisfy that the threshold condition of axiality, another parts are the most upwards installed.Every time using previous parts as benchmark,
The axiality of final requirement entirety is within the specific limits.This method takes a substantial amount of time, and the probability done over again is big, non-
The efficiency of often impact installation and one-time success rate, the most successfully assembling needs 4 to 5 days.And, because not being optimal dress
Coordination is put, it usually needs dismount 4 to 5 times, in addition it is also necessary to workman assembles with rich experiences, and each assembling is required for experiencing heat and adds
Work and cold working.So current aerospace engine assembly method installation effectiveness is low, it is difficult to install, and after assembling, axiality is poor,
Affect engine performance.
