Abstract
The utility model relates to a gas spring fatigue test frock, including the circular table that the level set up, radially set up a plurality of recesses that are used for holding the air spring on the workstation, the end of recess is equipped with the fixed pin, and the recess top sets up the preforming, is equipped with a lifter plate directly over the workstation, and lifter plate edge hinged has a plurality of connecting rods, connecting rod and recess one -to -one. The utility model discloses in placing the recess on the workstation with the air spring level, the one end of air spring is fixed, and the other end is articulated with the connecting rod, removes through the piston rod that makes the lifter plate go up and down to drive the air spring, has eliminated the influence of gravity in the experimentation, has improved the test accuracy.
Description
Technical field
This utility model relates to gas spring technology field, especially a kind of air spring fatigue test frock.
Background technology
Air spring fatigue machine is the duty of Simulated gas spring, tests to determine whether reach to design requirement to by gas test spring.When current air spring fatigue machine is tested, air spring is all vertically to place, and test result is affected bigger by gravity so that test result is the most accurate.
Utility model content
The technical problems to be solved in the utility model is: in order to when solving current air spring fatigue machine test, air spring is all vertically to place, test result is affected bigger by gravity, make the accurate not problem of test result, it is provided that a kind of air spring fatigue test frock.
This utility model solves its technical problem and be the technical scheme is that a kind of air spring fatigue test frock, including horizontally disposed circular table, radially some grooves for accommodating air spring are offered on described workbench, some described groove circumference uniform distributions, and one end of groove is towards the center of workbench, the end of described groove is provided with steady pin, groove is provided above tabletting, tabletting is fixing on the table, the surface of described workbench is provided with a lifter plate, described lifter plate edge is hinged with some connecting rods, described connecting rod and described groove one_to_one corresponding.Air spring is placed in groove on the table, the cylinder bottom of air spring connects seat to be fixed by steady pin, tabletting is pressed on air spring cylinder body and prevents air spring from leaving groove, one end of connecting rod is hinged with lifting platform, the other end is hinged with the connection seat of air spring piston bar, by making lifting of lifting table drivening rod move, so that the piston rod of air spring moves in cylinder barrel, the duty of Simulated gas spring, due to air spring horizontal positioned, in test process air spring by gravity affected less, improve the accuracy of test result.
Further, every air spring needs to overcome elastic force and frictional resistance in running, and therefore the driving means energy consumption of lifter plate is relatively big, and described lifter plate is by air cylinder driven, and described cylinder is arranged on the center of workbench, and described lifter plate connects the piston rod of cylinder.
Further, described lifter plate is driven by screw mechanism, and described table core is provided with through hole, and leading screw is arranged in described through hole, and described lifter plate is provided with nut, and one end of described leading screw connects motor output shaft.
The beneficial effects of the utility model are, this utility model is by air spring horizontal positioned groove on the table, one end of air spring is fixed, the other end and rod hinge connection, by making lifter plate lifting drive the piston rod of air spring to move, eliminate the impact of gravity in experimentation, improve test accuracy.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of embodiment 1；
Fig. 2 is the structural representation of embodiment 2.
In figure: 1. workbench, 2. groove, 3. steady pin, 4. lifter plate, 5. connecting rod, 6. cylinder, 7. leading screw, 8. motor, 9. air spring, 10. tabletting.
Detailed description of the invention
