Abstract
The utility model aims at providing a bush for fatigue testing of a horizontal guide rod testing clamp and a sample piece so as to reduce or avoid a phenomenon of bush replacement during the testing process. The bush is used for replacing a rubber bush, which is originally assembled, of the sample piece and is pressed into an outer cylinder of the sample piece. The bush is characterized in that the bush comprises an inner cylinder and a nylon bush body; and the inner cylinder and the nylon bush body are in interference fit.
Description
Technical field
The utility model relates to the torture test lining of horizontal guide rod test fixture and exemplar.
Background technology
Top rail for automobile is that each vehicle needs the bench test of considering to the guide rod test, generally the examination dynamic test for this class exemplar can last long, often in the situation that the rubber bushing of exemplar severe attrition, exemplar does not still complete certification test, and test must be proceeded after changing rubber bushing again.So this is undoubtedly to the trystate disunity, or the experimentation cost problem is all a defect.
The utility model content
The purpose of this utility model is to provide the torture test lining of horizontal guide rod test fixture and exemplar, to reduce or to avoid in process of the test the more situation of rebush.
The torture test lining of exemplar of the present utility model, for substituting the rubber bushing of the original assembling of exemplar, be pressed in the urceolus of exemplar, is characterized in, comprises inner core and nylon bush, between inner core and nylon bush, is interference fit.
Described torture test lining, wherein, the internal diameter of inner core, the external diameter of nylon bush are distinguished identical with the internal diameter of the inner core of described rubber bushing, the external diameter of rubber bushing.
Described torture test lining, wherein, the material of described inner core is metal.
Described torture test lining, wherein, the material of described inner core is No. 45 steel.
Top rail of the present utility model to the guide rod test fixture, is characterized in that, comprises column; Support member, can slide up and down to be arranged on column, and connect the end of top rail to the guide rod exemplar by aforesaid torture test with lining; Loading arm, connect the other end of top rail to the guide rod exemplar by described torture test with lining; And actuator, connect loading arm.
Adopt the torture test of the exemplar of rubber bushing to this class of guide rod for the picture top rail, the object of examining in test is exemplar but not lining, adopt rubber bushing in original test always, during test, must adopt cooling air unit to slow down liner wear, but still unavoidably repeatedly upgrade for completing test.The existing certain elasticity of aforesaid structure, simulation rubber bushing state, more wear-resistant than rubber bushing again, without cooling air unit, and can Reusability.
The accompanying drawing explanation
Fig. 1 is that top rail is to guide rod test fixture general assembly drawing.
Fig. 2 is main experimental fixture figure.
Fig. 3 is that the torture test of exemplar is surveyed view with the axle of lining.
Fig. 4 is that the top rail that is pressed into the nylon steel sleeve is surveyed view to the axle of guide rod exemplar.
Embodiment
As depicted in figs. 1 and 2, top rail comprises column 1 to the guide rod test fixture, support member 2, loading arm 5 and actuator 4.Support member 2 can slide up and down to be arranged on column 1, and connects the left end of top rail to guide rod exemplar 3 by torture test described later with lining 6.Loading arm 5 also uses lining 6 to connect the right-hand member of top rail to guide rod exemplar 3 by torture test.Actuator 4 connects loading arm 5.
As shown in Figure 3 and Figure 4, top rail has respectively urceolus 62 to the two ends, left and right of guide rod exemplar 3, and torture test comprises that with lining 6 inner core 60, nylon bush 61 and urceolus 62 form.
As shown in Figure 3, inner core 60, urceolus 62 are the same with the inside and outside cylinder of original lining, be for example No. 45 steel, and the lining in the middle of being positioned at is changed to nylon material by elastomeric material, utilize so novel (nylon steel) lining to substitute original rubber bushing, avoid whole test due to liner wear, need to repeatedly upgrade the problem of rubber bushing.The internal holes size of inner core 60 and the external dimensions of nylon bush 61 are simulated respectively the size of former lining, after two processing, adopt interference fit to form the nylon steel sleeve, finally whole lining are pressed into to the urceolus 62 of exemplar 3.The advantage of such Novel lining is not easy to wear after heating up, and need not re-use cooling air unit in order to slow down the lining life-span; Also without replacing, also saved time of rebush more and artificial, the consistance of warranty test state in test; After off-test, lining is extruded and can be used for for follow-up test, can Reusability, reduced cost.
Adopt the torture test of the exemplar of rubber bushing to this class of guide rod for the picture top rail, the object of examining in test is exemplar but not lining, adopt rubber bushing in original test always, during test, must adopt cooling air unit to slow down liner wear, but still unavoidably repeatedly upgrade for completing test.The existing certain elasticity of structure of aforesaid novel (nylon steel) lining (torture test lining), simulation rubber bushing state, more wear-resistant than rubber bushing again, without cooling air unit, and can Reusability.This technology can expand to the torture test (only examining exemplar not examine the dynamic test of lining) of the exemplar of all employing rubber bushings.
