This utility model achieves the testing fatigue of spring by punch press, expand the use occasion of equipment, reduce testing fatigue cost, reduce production cost, and, by upper end regulation spring and the setting of lower end cushion pad, greatly simulate the operating mode of absorber spring so that fatigue test data is the most true and reliable.
Accompanying drawing explanation
Fig. 1 show the structural representation of screw cylindrical spring fatigue test device of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in Figure 1, screw cylindrical spring fatigue test device of the present utility model includes upper bush 1, the slide block of its upper end and punch press is fixing to be connected and lower end is formed with inner retaining side, can slide up and down in upper bush be provided with sliding pallet 2, regulation spring 3 it is provided with between slide block and sliding pallet, described regulation spring can the stroke of auxiliary adjustment punch press, and truly simulate the applying working condition as absorber spring, improving the Actual Simulation of testing fatigue, described upper bush both sides are correspondingly provided with observing elongated hole to observe the duty of regulation spring；Lower sleeve 4, fixes with the workbench 5 of described punch press and is connected, i.e. described lower sleeve sinks to below the through hole of described workbench；And upper end fixes with described sliding pallet and is connected lower end and inserts the mandrel 6 within described lower sleeve matchingly, described mandrel includes the guiding bar 62 fixed the upper shaft part 61 being connected with sliding pallet and be formed at upper shaft part lower end coaxially, described lower sleeve center is fixedly installed striker 7, adpting flange it is formed with to be connected by bolt and described lower sleeve are fixing bottom described striker, described striker is centrally formed with and the described guide hole drawing matching guide bars, and described upper shaft part is arranged with spring 12 to be detected.Specifically, the cushion pad 8 that can contact it is provided with described upper shaft part lower surface on described striker top, described cushion pad top is provided with the filler ring 9 held with spring to be detected, utilizes the setting of cushion pad and filler ring, simulates the actual condition of absorber spring the most further.
This utility model achieves the testing fatigue of spring by punch press, the ram travel of punch press is adjustable, expand the use occasion of equipment, reduce testing fatigue cost, reduce production cost, and, by upper end regulation spring and the setting of lower end cushion pad, greatly simulate the operating mode of absorber spring so that fatigue test data is the most true and reliable.
Simultaneously, for improving the detection of axiality in work process, connect bottom described upper bush and have connection ring 10, outer cover at described spring to be detected is provided with detection pipe 11, connection is fixed with being connected ring in described detection pipe upper end, and striker receiving can wherein and relatively be moved up and down by described detection pipe lower end.So, during detection, between detected spring and detection pipe, relative motion can occur, if axiality is the best, then detection inside pipe wall can be caused to occur that cut even deforms, nationality is to provide reference.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
