Description
Technical field
The utility model relates to automotive field, particularly a kind of volute spring endurance test tool.
Background technology
Volute spring is the one of motor spring, compares leaf spring, and the energy that volute spring unit mass absorbs is many, and namely reach same elastic effect, its weight is less.Meanwhile, the longitudinal space that volute spring occupies is also little, is conducive to the densification of suspended structure.Therefore volute spring also just becomes a kind of conventional motor spring.And volute spring is as the flexible member on automobile hanging, mainly play the vibration of cutting down surface irregularity and causing, supporting suspension, the effect of lifting vehicle comfortableness.If volute spring lost efficacy, vehicle's center of gravity can be caused to offset, Vehicle handling reduction, comfortableness declines simultaneously.Therefore in Design and manufacturing process, volute spring endurance quality is an important Testing index, and testing volute spring endurance quality is quickly and accurately necessary work.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of volute spring endurance test tool, realizes testing fast and accurately volute spring endurance quality.
Embodiment of the present utility model provides a kind of volute spring endurance test tool, comprising: the first back up pad and the second back up pad and for fixing and support the first clamping plate and second clamping plate of described second back up pad; The side of described first back up pad is fixed with the first spring pedestal for fixing tested spring, described first spring pedestal is provided with for the guide rod when testing through tested spring, the opposite side of described first back up pad is provided with the actuator connector for being connected with actuator; The side of described second back up pad is fixed with the second spring pedestal for fixing tested spring, and the position described second spring pedestal and described second back up pad corresponding to described guide rod is respectively arranged with and makes the freely through through hole of described guide rod.
Alternatively, described first spring pedestal and described second spring pedestal are respectively by being bolted in described first back up pad and in described second back up pad.
Alternatively, described first clamping plate and described second clamping plate are L shape.
Alternatively, it is characterized in that, the quantity of described first spring pedestal and described second spring pedestal is two.
Technique scheme of the present utility model comprises following beneficial effect:
By arranging guide rod in the middle of volute spring, can prevent spring in test from occurring crack conditions and ejecting; First back up pad and the second back up pad can be connected with two sleeve spring stationary installations simultaneously, make above-mentioned frock can complete two helical spring long duration tests simultaneously, improve test efficiency, simultaneously also convenient contrast.
Accompanying drawing explanation
Fig. 1 is the vertical view of volute spring endurance test tool in the utility model;
Fig. 2 is the side view of volute spring endurance test tool in the utility model.
[Main Reference Numerals explanation]
1: actuator connector, 2: threaded hole, 3: guide rod, 4: through hole, 11: the first spring pedestals,
12: the first back up pads, 21: the second spring pedestals, 22: the second back up pads, a: the first clamping plate, b:
Second clamping plate.
Embodiment
Below with reference to accompanying drawings exemplary embodiment of the present disclosure is described in more detail.Although show exemplary embodiment of the present disclosure in accompanying drawing, however should be appreciated that can realize the disclosure in a variety of manners and not should limit by the embodiment set forth here.On the contrary, provide these embodiments to be in order to more thoroughly the disclosure can be understood, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
Refer to Fig. 1, the utility model provides a kind of volute spring endurance test tool, and this frock comprises: the first back up pad 12 and the second back up pad 22 and for fixing and support the first clamping plate a and the second clamping plate b of described second back up pad 22.Be fixed with the first spring pedestal 11 for fixing tested spring in the side of described first back up pad 12, the side of described second back up pad 22 is fixed with the second spring pedestal 21 for fixing tested spring.
In addition, continue to consult Fig. 1, described first spring pedestal 11 is provided with for when testing through the guide rod 3 of tested spring, and 22 positions corresponding to described guide rod 3 are respectively arranged with and make the freely through through hole 4 of described guide rod 3 on described second spring pedestal 21 and described second back up pad.In test described guide rod 3 can be passed tested spring by said structure, effectively can prevent spring in test from ejecting because of problems such as fractures like this, thus play the effect of prevention & protection.And owing to needing to use actuator in process of the test, therefore the opposite side of described first back up pad 12 is provided with the actuator connector 1 for being connected with actuator.Actuator can be tested by the long duration test be connected with frock for spring of described actuator connector 1 and provide power.
Refer to Fig. 2, because whole frock needs stable fixing in test, therefore described first clamping plate a and described second clamping plate b can be designed to L shape, described first clamping plate a and described second clamping plate b can be realized the fixing of whole frock, carrying out smoothly of warranty test by another Boards wall on iron ground like this.
Continue to consult Fig. 1, described first spring pedestal 11 and described second spring pedestal 21 to be fixed by bolts in described first back up pad in 12 and described second back up pad 22 respectively by threaded hole 2.And described volute spring endurance test tool comprises two described first spring pedestals 11 and two described second spring pedestals 21.So just disposablely can complete two helical spring test jobs, improve testing efficiency.It is appreciated of course that, do not limit the quantity of the first spring pedestal 11 and the second spring pedestal 21 in the present embodiment.
The utility model, by arranging guide rod in the middle of volute spring, can prevent spring in test from occurring crack conditions and ejecting; Two back up pads can be connected with two sleeve spring stationary installations simultaneously, make this frock can complete two helical spring long duration tests simultaneously, improve test efficiency, simultaneously also convenient contrast.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
