Description
Technical field
The utility model relates to a kind of test unit, specifically relates to a kind of steel plate spring assembly fatigue tester of fatigue strength of leaf spring.
Background technology
In our life, all use leaf spring on a lot of articles for use.Leaf spring obtains general use because of its structural strength height, across advantages such as distance are big.Effects such as leaf spring generally is used for supporting, vibration damping such as the leaf spring on the automobile, the leaf spring on the train etc., are not only supported the parts on top, and can the vibration that transmit up on ground be absorbed, and play buffer action.Prevent bigger vibration transfer to top, alleviate driver and occupant's the sense of jolting.Therefore, after these vehicle operatings are got up, the up-down vibration that leaf spring can be frequent, amplitude varies.This just has very high requirement to the fatigue strength of leaf spring, if the fatigue strength of leaf spring is not enough, through after the vibration of regular period, leaf spring may occur can not returning to original state after crackle, fracture or the distortion, promptly produced nonvolatil distortion, made leaf spring lose effect.Therefore the fatigue strength detection to leaf spring is an important link.
Some used leaf spring fatigue tester complex structures all are some huge monsters at present, and load maintainer weight very needs huge power to drive, and therefore also causes the cost cost higher, also needs to take very big place, detect also inconvenient.
The utility model content
For solving the deficiencies in the prior art, it is a kind of simple in structure, easy to operate that the purpose of this utility model is to provide, lower-cost steel plate spring assembly fatigue tester.
For achieving the above object, the utility model is to realize by following technical scheme:
A kind of steel plate spring assembly fatigue tester, it is characterized in that comprising servo hydraulic cylinder, pillar, displacement transducer, base and pillar anchor clamps, middle part at base is equipped with support, fixing servo hydraulic cylinder on support, the piston rod of described servo hydraulic cylinder is equipped with anchor clamps at the head of piston rod down; At the outside of servo hydraulic cylinder fixed installation displacement transducer, the sensing head of displacement transducer is connected with piston rod; Two ends at base are respectively equipped with pillar, and the bottom of pillar is processed with threaded hole, and screw rod therefrom passes; The two ends of screw rod are installed on the base by bearings, at an end of screw rod handwheel are housed; Inboard at two pillars is equipped with the pillar anchor clamps respectively, and the end of pillar anchor clamps reaches the inside of pillar, also is processed with threaded hole in the end of pillar anchor clamps, cooperates with screw rod, and the head of screw rod reaches the top of pillar, and handwheel is housed.
Aforesaid steel plate spring assembly fatigue tester is characterized in that also being provided with the servo-hydraulic system, and described servo-hydraulic system communicates with servo hydraulic cylinder by hydraulic tube.
Aforesaid steel plate spring assembly fatigue tester is characterized in that also comprising outer computer, and outer computer connects the servo-hydraulic system by signal wire.
The beneficial effects of the utility model are: the utility model is simple in structure, and is easy to operate, takes up an area of to lack, and cost is lower, can carry out accurate torture test to leaf spring, guaranteed the preceding quality conformance with standard regulation of product installation, guaranteed product percent of pass.
Description of drawings
Fig. 1 is the structural representation of steel plate spring assembly fatigue tester of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done concrete being described below.
Fig. 1 is the structural representation of steel plate spring assembly fatigue tester of the present utility model.As shown in the figure, steel plate spring assembly fatigue tester of the present utility model, comprise servo hydraulic cylinder 1, pillar 6, displacement transducer 8, base 4 and pillar anchor clamps 5 etc., in the middle part of base 4 support 9 is installed, fixing servo hydraulic cylinder 1 on support 9, servo hydraulic cylinder 1 is communicated with outside servo-hydraulic system (not shown) by hydraulic tube.The piston rod of servo hydraulic cylinder 1 is equipped with anchor clamps 2 at the head of piston rod down; At the outside of servo hydraulic cylinder 1 fixed installation displacement transducer 8, the sensing head of displacement transducer 8 is connected with piston rod; Be respectively equipped with pillar 6 at the two ends of base 4, the bottom of pillar 6 is processed with threaded hole, and screw rod 3 therefrom passes; The two ends of screw rod 3 are installed on the base 4 by bearings, at an end of screw rod 3 handwheel 7 are housed.After being provided with like this, pillar 6 can be on base 4 move left and right, the distance of regulating 6 on two pillars as required.
Inboard at two pillars 6 is equipped with pillar anchor clamps 5 respectively, and the end of pillar anchor clamps 5 reaches the inside of pillar 6, also is processed with threaded hole in the end of pillar anchor clamps 5, cooperates with screw rod, and the head of screw rod reaches the top of pillar, and handwheel 7 is housed.Make that pillar anchor clamps 5 also can up-down adjustment.
During test, pillar 6, pillar anchor clamps 5 are adjusted to behind the suitable position according to actual needs fixing, leaf spring are clamped carry on two pillar anchor clamps 5, the anchor clamps 2 with servo hydraulic cylinder 4 piston rod heads are clipped on the leaf spring again.Computer control servo-hydraulic system, and then the action of control servo hydraulic cylinder 1.Moving up and down of piston rod by servo hydraulic cylinder 1 drives the leaf spring knee-action.Because the two ends of leaf spring are fixed, so under the effect of anchor clamps 2, the middle part of leaf spring moves up and down repeatedly, and leaf spring is carried out Stromeyer test.Displacement transducer 8 is used for detecting the amplitude up and down of leaf spring, and detects torture test rear spring deflection.
The utility model can be realized the automatic control of computing machine, and vibration frequency can be set, and displacement also can be set according to testing requirements, and is convenient, simple, accurate.
The foregoing description does not limit the utility model in any form, and all technical schemes that mode obtained of taking to be equal to replacement or equivalent transformation all drop in the protection domain of the present utility model.
