Description
Technical field
The present invention relates to a kind of fatigue tester, especially a kind of auto-bank unit guide tube high-cycle fatigue test device.
Background technology
Before many aeronautical products are delivered at present or after repairing, it is required for doing a series of experiment, to ensure the use of product
It is required that.Aviation main decelerator of driving system auto-bank unit guide tube, requirement carries out chromium plating on surface, resistance to increase surface
Mill property and improvement surface property.In use, it because applying working condition complexity frequently results in chrome layer blistering, influences to use, need
Again it to repair.Conventional repair scheme is after removing all coating, rechroming and is machined to prescribed requirement as required,
Then specification of technical file is pressed, needs to carry out high cycle fatigue examination after repairing auto-bank unit guide tube coating.When examination, it is specified that
For test load force direction perpendicular to auto-bank unit guide tube central axis, test load is pressure, test number (TN) hundreds of
Ten thousand times, at present often without such exerciser.
Invention content
The object of the present invention is to provide an auto-bank unit guide tube high-cycle fatigue test devices, realize aviation transmission system master
The technology requirement of retarder auto-bank unit guide tube high-cycle fatigue test carries out testpieces the load of load step by step, and examination is certainly
Fatigue life after dynamic inclinator guide tube coating reparation.
The technical scheme is that wing drop guide tube high-cycle fatigue test device include heavy frame, oil cylinder, sensor,
Adapting rod, reinforcing bar assembly, mounting disc, force-bearing base.Testpieces is mounted on by mounting disc on force-bearing base, and the center of testpieces
Axis horizontal, oil cylinder are mounted on the upper beam of heavy frame, and sensor, adapting rod, reinforcing bar assembly are installed in oil cylinder lower part successively,
It reinforces bar assembly to be mounted on testpieces, the oil cylinder, sensor, connecting rod, the axis for reinforcing bar assembly and horizontal plane hang down
Directly；The reinforcing bar assembly includes the connecting rod being connect with adapting rod, installs the oscillating bearing and fixing joint of testpieces
The outer shroud of the end cap of bearing, the oscillating bearing is integrated, lateral opening, and corner-kick is pressed into outer shroud from side；The corner-kick
Material be aircraft aluminum, spherical surface carries out hard anodized and spray treatment.
In the use of the present invention, auto-bank unit guide tube is fastened on bolt on force-bearing base, reinforcing bar assembly is mounted on certainly
On dynamic inclinator guide tube, adapting rod, sensor, the piston rod for connecting oil cylinder are connected；Connect pickup wire, servo valve line, substation
Line.Motor drives oil pump, and high pressure oil is transmitted to pressure distributor by high-pressure oil pipe, will by oil cylinder and reinforcing bar assembly
Impulse load, which is applied on testpieces, generates transient state fatigue, and the force snesor being installed together at this time with testpieces will be by force signal
TT＆C system is fed back to, closed-loop control is carried out to load by TT＆C system.Fatigue loading is carried out to testpieces.
The auto-bank unit guide tube high-cycle fatigue test device that the present invention is designed and manufactured, entire exerciser is closed load
Mechanism, heavy frame, force-bearing base and the iron bottom plate that modular force-bearing piece is combined into constitute the load mechanism of a closure, realize
Load requirement to the load of testpieces big load.Reinforcing bar assembly in be designed with oscillating bearing, can automatic aligning, bear larger
Test load.The outer ring design of oscillating bearing uses overall structure, is pressed into corner-kick, it is 4 tons of test pressures that can bear initial load, is made
Use long lifespan.The material of the coating of the inside corner ball failure test part of oscillating bearing in order to prevent, inside corner ball uses aircraft aluminum.Ball
The processing such as face hard anodized, spraying, therefore oscillating bearing has larger load-carrying ability and impact resistance, and there is anti-corruption
Erosion, wear-resistant, Self-aligning, the feature lubricated.Exerciser can simulate the actual working state of auto-bank unit guide tube, examination
Fatigue life after the reparation of auto-bank unit guide tube coating.Exerciser reliability is high, durability is strong, and installation operation is simple, is convenient for
It safeguards.
