Description

Aeroengine rotor assembly method and the device of swivel angle plate is adjusted based on regulation of mental activities
Technical field
The invention belongs to mechanical assembly technique, relate generally to a kind of aero-engine adjusting swivel angle plate based on regulation of mental activities Rotor assembling 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 work efficiency have material impact for quality, performance and the production efficiency of electromotor.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.
Along with aero-engine assembling measuring technology increasingly comes into one's own, aero-engine assembling measuring technology Increasingly come into one's own, and become the focus of research.Increasing research worker 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 being obtained the stress signal of rotor each position, main system The signal that each subsystem gathers is analyzed, damages the Parameter analysis impact on assembling 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 geometric sense aspect impact on assembling, it is impossible to improve the geometric sense impact on assembling.
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 closed;Then the aviation to the multicarrier coupling obtained The impulse response signal of engine rotor uses dual-tree complex wavelet transform method to be analyzed, it is thus achieved that eight single loads The impulse response subsignal of the aeroengine rotor of ripple;The finally aviation to eight single carriers obtained is sent out The impulse response subsignal of motivation rotor extracts average assembly performance index, if the average assembly performance of gained refers to Scale value is more than or equal to 10, then judge that the assembling of this aeroengine rotor is qualified, if the meansigma methods of gained is less than 10, then judge defective, need to do over again rebuilding.The method there is a problem in that not to aeroplane engine Machine rotor assembling is instructed.
Luoxin Precision Parts (shanghai) Co., Ltd. proposes one measurement axiality equipment, and (a kind of axiality is surveyed Amount instrument.Publication number: CN202024752U).This device includes a pair be arranged on apparatus subject by synchronizing The transmission main shaft that mechanism's Synchronization Control rotates, this transmission main shaft the inner is correspondingly arranged on measurement head and location respectively Datum level;Above position, there is transducer probe assembly between described measurement head.It mainly solves existing accurate zero The axiality of part, the measurement beated.The method there is a problem in that the axiality only measuring measured piece, Do not solve the problem of axiality difference after rotor assembles.
Liming Aeroplane Engine (Group) Co., Ltd., Shenyang City proposes a kind of gap measuring method and (starts Machine rotor blade tip radial clearance contactless measurement.Publication number: CN102175135A).The method is adopted Using capacitance measurement technology, measuring process is as follows, and first assembling measurement system, calibration sensor, determine leaf Relation between point radial clearance and voltage, then sensor is fixed on blade, finally measure electromotor and turn Cotyledon point radial clearance.The method there is a problem in that during not accounting for rotor assembling axially mounted Impact after rotor assembles.
The test of aero-engine assembling, to liking stators and rotor, meets requirement in component processing precision 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 electromotor.High-performance enginer work High speed rotating speed when making is more than 10000rpm, and single part axially or radially beat will necessarily cause the turbine disk Center deviation engine rotation axis, can produce the biggest centrifugal force in such a situa-tion, cause rotor The imbalance rotated, 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 " Fructus Musae ", 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 In satisfied use requirement.
At present, domestic engine assembly still uses traditional assembly method, tests manually with amesdial It is main.According to assembled in sequence electromotor 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, the most upwards installs another parts. Every time using previous parts as benchmark, the axiality of final requirement entirety is within the specific limits.This side Method takes a substantial amount of time, and the probability done over again is big, affects very much efficiency and the one-time success rate of installation, The most 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 is required for experiencing hot-working every time And cold working.So current aerospace engine assembly method installation effectiveness is low, it is difficult to install, and after assembling Axiality is poor, affects engine performance.
Summary of the invention
The deficiency existed for above-mentioned prior art, proposes a kind of aero-engine adjusting swivel angle plate based on regulation of mental activities Rotor assembling method and device, to solve the problem that after aeroengine rotor assembles, axiality is low, reach to turn After son assembling, axiality is high, reduction is vibrated, be easily installed, flexibility ratio is high, improve the purpose of engine performance.
