Abstract
The invention relates to a fatigue endurance test of automobile damper bumper blocks, in particular to a fatigue endurance test tool for automobile damper bumper blocks. The tool comprises a piston rod I and a piston rod II connected with the piston rod I, an upper pressing cover is arranged on the joint of the piston rod I and the piston rod II, a height adjusting device is arranged at the bottom of the piston rod II, and a sleeve is arranged at the bottom of the height adjusting device. The fatigue endurance test tool has the advantages that accuracy of bumper block fatigue endurance test results can be guaranteed, tool reliability is high, the tool manufacturing cycle is reduced, and raw materials and manpower are saved.
Description
Technical field
The present invention relates to automobile absorber buffer stopper fatigue endurance test.
Background technology
Automobile absorber buffer stopper plays very important effect in vibration damper assembly, and therefore buffer stopper must have good permanance and anti-fatigue ability, and the fatigue endurance test of buffer stopper is inspection buffer stopper performance effective means whether up to standard.There is impact in damping effect and the life-span of the quality of buffer stopper on vibroshock, and the comfortableness of vehicle is also had to impact.In the past, every kind of buffer stopper fatigue endurance test all will do separately a set of frock, not only wasted material but also be not easy to administering and maintaining of frock.
Summary of the invention
The invention provides a kind of automobile absorber buffer stopper fatigue endurance test frock, simple in structure, can carry out fatigue endurance test to different pore size and differing heights buffer stopper.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of automobile absorber buffer stopper fatigue endurance test frock, it is characterized in that: comprise the piston rod I and the piston rod II that link together, joint portion between piston rod I and piston rod II is provided with upper press cover, piston rod II bottom is provided with arrangement for adjusting height, and described arrangement for adjusting height bottom is provided with sleeve.
The invention has the beneficial effects as follows: can ensure the accuracy of the tired durability experiment result of buffer stopper, the reliability of frock is strong, has reduced the cycle of frock making, has saved starting material and manpower.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure: 1. piston rod I, 2. upper press cover, 4. piston rod II, 5. arrangement for adjusting height, 6. sleeve.
Embodiment
As shown in Figure 1, comprise the piston rod I 1 and the piston rod II 4 that link together, joint portion between piston rod I 1 and piston rod II 4 is provided with upper press cover 2, upper press cover 2 profiles are bottom-up barrel-like structure, piston rod II 4 bottoms are provided with arrangement for adjusting height 5, arrangement for adjusting height 5 upper ends can freely be dismantled, and height can regulate as required.Described arrangement for adjusting height 5 bottoms are provided with sleeve 6.
Piston rod I 1 upper end is connected with servo fatigue testing machine, and buffer stopper 3 matches with upper press cover 2 and piston rod II 4, according to the aperture of buffer stopper 3 and height, adjusts upper cover aperture and the whole height of arrangement for adjusting height 5, and sleeve 6 plays padded effect.
When use, according to the aperture of buffer stopper 3 and height, select the piston rod II 4 of suitable diameter and length, and select suitable aperture arrangement for adjusting height 5 removable upper covers, adjust height, each part is connected successively, adjust testing requirements parameter and can test.
