The machine of the experiment on fatigue properties of varying duty.Fatigue tester concentricity has vital influence to the fatigue behaviour of material.
JBT9397-2002《Repeated tension and compression test machine technical conditions》, JJG556-2011《Axial reinforcing fatigue tester》In to fatigue
The concentricity of testing machine proposes technical conditions requirement and detection method.But in reality production, processing, due to fatigue tester
Parts machining error and rigging error presence, inevitably there is coaxiality error in fatigue tester, and then influence
The test data and result of fatigue tester.
Utility model content
The purpose of this utility model is that there are coaxiality errors in for the above-mentioned prior art, test result is influenced, is carried
For a kind of concentricity adjusting apparatus of fatigue tester, the coaxiality error purpose of fatigue tester is effectively controlled, improves experiment
The precision of data.
In order to solve the above technical problems, the utility model adopts the following technical solution：
A kind of concentricity adjusting apparatus of fatigue tester, including lower adjusting seat, lower dolly bar, upper adjusting rod, upper adjusting
Seat, adjusting bolt, locking nut and two groups of tight fixed bolts；The lower adjusting seat is oppositely arranged with upper adjusting seat, and by described
Two groups of tight fixed bolts be connected；The upper surface of described lower adjusting seat it is opposite with below upper adjusting seat be equipped with the first groove and second
Groove；The lower dolly bar is through the first groove and the adjusting bolt by being disposed longitudinally in the first groove clamps；It is described
Upper adjusting rod passes through the second groove and the adjusting bolt by being disposed longitudinally in the second groove clamps；The upper adjusting rod it is upper
End is additionally provided with locking nut for locking upper adjusting rod and upper-part.
It is further, equably radially arranged in the first groove of the lower adjusting seat that there are four threaded hole, the adjustings
Bolt is arranged in correspondence in threaded hole and forms compression fit with threaded hole.
It is further, equably radially arranged in the second groove of the upper adjusting seat that there are four threaded hole, the adjustings
Bolt is arranged in correspondence in threaded hole and forms compression fit with threaded hole.
The utility model proposes fatigue tester concentricity adjusting apparatus, may be implemented ensure properties of product not by
Under the premise of influence, the coaxiality error of fatigue tester is controlled；And it is simple in structure, easy for installation, improve test data and
As a result reliability.
