Background technology
The damper be made up of valve block plays very important effect in cylindrical automobile shock absorber, the effective attenuate ground of energy is to the vibration of vehicle, reduce the inertial force of vehicle and occupant, the stationarity travelled car load, the stability of manipulation, comfortableness, braking and security etc. have important impact.Therefore the serviceable life of valve block is one of leading indicator of telescopic shock absorber, in order to ensure the performance and used life of valve block, needs to detect serviceable life style in the process of its batch production.But because the test in serviceable life of single valve block part needs the time oversize, so some employing accelerated test methods, improve the running speed of test machines or strengthen the acting force of test, increase its amplitude or frequency, very unfavorable to testing equipment itself like this, be difficult to reach desirable running speed, make the result of test and actual damping there is larger discrepancy with the difference of actual motion.The torture test in existing air hanging device for car valve block serviceable life does not still have special testing equipment, but make valve block produce movement up and down or around by the structure of oscillatory type or single cam, the direct serviceable life of overload operation on air hanging device for car being tested to examination valve block also had.Like this, no matter adopt which kind of method to test all existence operation power consumption and experimentation cost increasing the serviceable life to air hanging device for car valve block, and test findings and vibroshock actual motion have some gaps.
Summary of the invention
In order to the time overcoming existing automobile absorber valve block torture test needs is long, test findings and actual motion have certain gap, test power consumption is many, the deficiency that experimentation cost is high, the utility model provides a kind of valve block deflection deformation fatigue tester, and it can not only press valve block actual operating mode, shortens test period, test data is accurate, and power consumption is few, experimentation cost reduces.
The utility model solves the technical scheme that its technical matters adopts: by deflection regulating device, follower lever, the valve block deflection deformation fatigue tester of deformation device base composition, motor shaft is provided with the deflection regulating device of band adjustment bolt, the bottom of deflection regulating device is provided with roller, roller is arranged in the rolling wheel support of follower lever upper end, the bottom of rolling wheel support is provided with retracing spring and spring base, be arranged on the reducing position, bottom of the follower lever on deformation device support, successively upper flat plate is installed from top to bottom, distortion trim ring, test valve block, deformation device base and lower flat board, the bottom of lower flat board is hold-down nut.
Described test valve block, the internal diameter of the distortion trim ring on its top is greater than the internal diameter of test valve block.
Described deflection regulating device is made up of the cam of 6 different rises, and its rise is respectively 0.10mm, 0.15mm, 0.20mm, 0.25mm, 0.30mm, 0.35mm.
Described follower lever is arranged on deformation device support, slides up and down.
The inclined-plane of described deformation device base and the angle of surface level are 50 °.
The beneficial effects of the utility model are simpler, convenient to the torture test in serviceable life of air hanging device for car valve block, substantially reduce test period, reduce experimental cost, and steadily stressed, transmission high efficiency, is applicable to high speed test.

Embodiment
In FIG, in order to make the technical solution of the utility model clearly, below in conjunction with drawings and Examples, the utility model is further described.Specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.Motor (1) axle is provided with the deflection regulating device (3) of band adjustment bolt (2), the bottom of deflection regulating device is provided with roller (4), roller is arranged in follower lever (9) upper end rolling wheel support (5), and the bottom of rolling wheel support is provided with retracing spring (6) and spring base (7).The higher pair contact structures of this follower lever, can make follower lever obtain continuous print desired movement when moving.When cam is constant velocity rotation, its curved profile, by the roller contact with distortion follower lever top, makes follower lever (9) regular lifting.Be provided with upper flat plate (10), distortion trim ring (11), test valve block (12), deformation device base (13) and lower flat board (15) from top to bottom successively at the reducing position of follower lever bottom, the bottom of lower flat board is hold-down nut (14).The internal diameter of the distortion trim ring (11) on test valve block (12) top is greater than the internal diameter of test valve block.Deflection regulating device (3) is made up of the cam of 6 different rises, and its rise is respectively 0.10mm, 0.15mm, 0.20mm, 0.25mm, 0.30mm, 0.35mm.Follower lever is arranged on deformation device support, slides up and down.The inclined-plane of deformation device base (13) and the angle of surface level are 50 °.This structure easily realizes the result of test valve block deflection deformation test closer to actual operating mode.
During test, deflection regulating device (3) rotates under the drive of motor, the resistance that the roller (4) being located at follower lever top overcomes retracing spring under the promotion of deflection regulating device (3) cam profile runs downwards, be stuck in the upper flat plate (10) at follower lever reducing position along with downward operation, upper flat plate 10) the distortion trim ring of bottom is along with being pressed in test valve block (12), be greater than the upper end that the internal diameter of test valve block and test valve block bottom be provided with the distortion base at 50 ° of angles withstand on the internal diameter of test valve block owing to being out of shape the internal diameter of trim ring, force the downward deflection deformation of test valve block.When the cam base circle profile part in deflection regulating device (3) forwards roller (4) to, under the effect of retracing spring, drive follower lever and the upper flat plate be installed on it, distortion trim ring and test valve block upwards to run, test valve block recovers normal condition.Along with the rotation of motor, the cam profile pushing rolling wheels again of deflection regulating device (3), the resistance making follower lever again overcome retracing spring runs downwards, the deflection deformation again of test valve block.So, go round and begin again, along with moving back and forth of follower lever, promote test valve block and constantly carry out deflection deformation, utilize counter and calculate according to methods such as motor rotations the fatigue data testing valve block deflection deformation.
