The invention discloses a steel plate spring assembly impact resistance testing machine, comprising a front supporting seat, an air cylinder or an oil cylinder, an upper fixing plate, a lower fixing plate, a connector, two guide pillars, and a rear supporting seat. The steel plate spring assembly comprises a front lifting lug seat and a rear lifting lug seat; the steel plate spring assembly is fixedly connected to the front supporting seat and the rear supporting seat through the front lifting lug seat and the rear lifting lug seat. The air cylinder or the oil cylinder is fixedly arranged between the upper fixing plate and the lower fixing plate; a piston rod is fixedly connected to the steel plate spring assembly. The work principle of the machine is simulating the real road condition of an automobile driving on road and repeatedly applying instantaneous impact loads to the tested steel plate spring assembly using the instantaneous work pressure produced by the air cylinder or the oil cylinder to determine and test the impact-resistance strength and fatigue life of the tested steel plate spring assembly, and at the same time to test the impact-resistance strength of the front lifting lug seat and the rear lifting lug seat of the test steel plate spring assembly. The machine having a broad test range, accurate and reliable test results, high efficiency, low cost, and strong practicality, is an effective test method for determining the product quality of steel plate springs and lifting lugs.
Description
Technical field
The present invention relates to automobile leaf spring production technical field, particularly relate to a kind of steel plate spring assembly fatigue test board.
Background technology
Automobile leaf spring is the vitals of automobile suspension system, to vehicle complete vehicle technical feature and security performance most important, in vehicle traveling process, because pavement behavior can cause the severe jolt of automobile to vibrate, make the suspension system of automobile, especially leaf spring bears larger shock load, thus has a strong impact on causing the fatigue lifetime of automobile leaf spring, and brings potential safety hazard to the traffic safety of automobile.Therefore, at leaf spring production link, especially in factory inspection link, impulse test need be carried out to leaf spring, whether reach quality inspection standard with the impact strength detecting leaf spring.To this, general manufacturer is many endurance life and impact strengths being detected leaf spring by proving ground test now, but this road method for testing needs service testing, experimentation cost is high, expend time in length, and be difficult to obtain test data, be unfavorable for electronic management product information and follow-uply provide test basis for improving spring performance.
Summary of the invention
For the problems referred to above, the present invention proposes a kind of steel plate spring assembly impact test platform, by the impulse test to steel plate spring assembly, can simulated automotive road conditions, and the product quality of test verification leaf spring, effectively solves the deficiencies in the prior art.
The technical solution used in the present invention is:
Steel plate spring assembly impact test machine, comprise front bearing, cylinder or oil cylinder, upper mounted plate, bottom plate, connector, guide pillar, rear support, steel plate spring assembly comprises front lifting eye seat and rear lifting eye seat, steel plate spring assembly is fixedly connected with rear support with front bearing respectively by front lifting eye seat and rear lifting eye seat, described cylinder or oil cylinder are fixedly mounted on upper mounted plate and bottom plate, described cylinder or cylinder piston rod are fixedly connected with steel plate spring assembly by connector, and namely the middle part of steel plate spring assembly is fixedly connected with cylinder or cylinder piston rod; Described front bearing 1 and rear support 10 are connected as a single entity by base.
Principle of work of the present invention is the actual road conditions of simulated automotive road driving, and the instantaneous working pressure utilizing cylinder or oil cylinder to produce applies temporary impact load to tested leaf spring, repeatedly to judge impact strength and the fatigue lifetime of checking tested leaf spring.
The present invention is by before being fixedly mounted on the two ends lifting eye seat of steel plate spring assembly, on rear support, and be connected in the middle part of spring with cylinder or cylinder movement portion, can real simulation running car time the steel plate spring assembly shock load of bearing, repeatedly carry out impact test and test fatigue lifetime, and test period and magnitude of load all can be controlled by computer programming, test findings can carry out data processing by computing machine, intuitively can obtain the strained situation of test findings and leaf spring, compared to existing technology, there is structure simple, test result accurately and reliably, experimentation cost is low, be easy to operation, efficiency is high, the features such as strong adaptability, the steel plate spring assembly batch that can be applicable to different size model carries out impact test, it is the effective detection means judging leaf spring capability and performance.
In addition, when adopting the present invention to carry out leaf spring impulse test, because tested leaf spring is equipped with front lifting eye seat and rear lifting eye seat, therefore, in test, the front lifting eye seat of leaf spring and the impact strength of rear lifting eye seat can be detected in the lump, achieve multi-functional same machine testing, substantially increase sensing range and efficiency, it is practical.
