Abstract
The utility model discloses a kind of fastener fatigue test frock, including handgrip, upper frock, lower frock and handgrip under fatigue tester on fatigue tester, upper frock is by being arranged on fatigue tester in handgrip, lower frock is arranged under fatigue tester in handgrip and its end and stretches on fatigue tester in handgrip, experiment bolt is fastened between frock and lower frock, and upper frock is 40CrNiMoA materials with lower frock.By using above-mentioned technical method, the Advantageous Effects that the utility model is obtained to be：The fastener fatigue test frock increased frock working sections product, have adjusted the anti-fatigue performance of frock, realize the characteristics of reliable process of the test, stabilization, data are accurate, dismounting is quick.Improve anti-fatigue performance.Make that process of the test reliable, stabilization, data are accurate, dismounting is quick.
Description
Technical field
The utility model relates to fastener fatigue test technology field, more particularly to a kind of fastener fatigue test frock.
Background technology
Existing fatigue test frock, material is Cr12MoV, including test tool upper frock and lower frock, in examination
Because upper frock counterbore is deeper during testing, test tool machined 40 × 27 square opening as pulling on the face of cylinder of φ 60
Groove is twisted, causes the use net sectional area of frock to diminish, when experiment bolt is installed, it has not been convenient to carry out twisting, mounted and dismounted
Taken during experiment bolt more long.Working sections product due to frock in process of the test is smaller（About 605 square millimeters）, doing
During the bolt fatigue test of the high-strength material of high temperature alloy and titanium alloy, often there is test tool rupture（According to experimental technique
Standard requirement, bolt minimum 45000 times of single-piece of fatigue is average >=60000 times, the frock for using often at 30000 times or so just
Fail）, cause test failure, it is that the process of the test of product brings unreliable, unstable, inaccurate hidden danger, run counter to
The requirement of process of the test.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of fastener fatigue test frock, the test tool makes
With in high frequency fatigue test equipment, with fatigue behaviour stabilization, frock intensity reliability in process of the test, there is provided experiment inspection
Data reliability is surveyed, the surface structure size for changing product is easily installed and dismantles.To improve fastener bolt test data
Accuracy rate and installation effectiveness.
A kind of fastener fatigue test frock, including handgrip, upper frock, lower frock and fatigue tester on fatigue tester
Lower handgrip, by being arranged on fatigue tester in handgrip, lower frock is arranged under fatigue tester in handgrip and it upper frock
End is stretched on fatigue tester in handgrip, and experiment bolt is fastened between frock and lower frock, and upper frock is with lower frock
40CrNiMoA materials.
Further, the upper frock of the fastener fatigue test frock carries out frock material with lower frock using heat treatment method
It is quenched, it is quenched between HRC36~42.
By using above-mentioned technical method, the Advantageous Effects that the utility model is obtained to be：The fastener fatigue test
Frock increased frock working sections product, have adjusted the anti-fatigue performance of frock, realize reliable process of the test, stabilization, data
Accurately, the characteristics of dismantling quick.Improve anti-fatigue performance.Make that process of the test reliable, stabilization, data are accurate, dismounting is quick.

Fig. 4 is working sections figure of the present utility model；
In figure, 1, handgrip on fatigue tester；2nd, upper frock；3rd, test screw；4th, lower frock；5th, under fatigue tester
Handgrip.
Specific embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining practical new
Type, is not intended to limit scope of the present utility model.
A kind of fastener fatigue test frock, including handgrip 1, upper frock 2, lower frock 4 and fatigue examination on fatigue tester
Handgrip 5 under machine is tested, upper frock 2 by being arranged on fatigue tester in handgrip 1, under being arranged on fatigue tester grab by lower frock 4
Hand 5 is interior and its end is stretched on fatigue tester in handgrip 1, and experiment bolt 3 is fastened between frock 2 and lower frock 4, upper work
It is 40CrNiMoA materials that 2 are filled with lower frock 4.Processed by the preferable 40CrNiMoA materials of the selection of material dynamic mechanical and produced
Product frock, the structure of test tool is adjusted, and the surface structure spy's size to test tool is improved, process
Middle use heat treatment carries out quenched raising anti-fatigue performance.So as to reach, reliable process of the test, stabilization, data are accurate, it is fast to dismantle
Prompt purpose.The use net sectional area of test tool is improved to 1797 square millimeters from 605 square millimeters.Using heat treatment side
Method carries out the quenched of frock material, between HRC36~42, effectively increases the fatigue resistance of test tool, shock resistance,
According to the actual performance situation of product, the only unqualified bolt fracture of properties of product in actual process of the test, test tool is normal
Often according to the top performance of product, accomplish 130000 times it is unbroken, effectively solve the unstable situation of process of the test.Ensure
The accuracy of the test data of product, reliability.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all in this practicality
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model
Within the scope of shield.
