Abstract
The technical scheme adopted by the invention is as follows: a fuel tank cap fatigue test bed is composed of a fatigue test device, a U-shaped support and a base. The fatigue test device can simulate the situation that a person opens and closes the oil tank cap of an entity vehicle in actual life, and the requirements of different height positions of the oil tank caps of different vehicle types are met by adjusting the position of the sliding block on the U-shaped support. When the test is initial, the push rod is in an extending state, one end of the nylon rope is fixed on the oil tank cover of the solid vehicle, and the other end of the nylon rope is fixed on the unthreaded hole of the idler wheel. The electric cylinder data instruction in the oil tank cap fatigue test stand is given through the computer, the push rod contracts, the oil tank cap of the solid vehicle is stretched to a limit angle through the nylon rope, then the electric cylinder data instruction is given again through the computer, the push rod stretches out, and the oil tank cap of the solid vehicle is pressed through the idler wheel to be closed. After the reciprocating test, when the oil tank cover of the entity vehicle drops, the test stops.
Description
The technical field is as follows:
the invention relates to a lifting type oil tank cover fatigue test bed, in particular to a repeated fatigue test for an automobile oil tank cover, and belongs to the field of engineering machinery.
Background art:
in modern traffic development, the automobile industry is rapidly developing, and the safety performance of automobiles is very important for the safety of drivers and society. Whether it accords with national standard can be judged to the fatigue test of automobile parts, carries out the fatigue test through the people and reciprocates switch fuel tank cap, not only makes staff intensity of labour increase, and work efficiency is low moreover. In view of this, a lifting type oil tank cap fatigue test bed is urgently needed in the industry.
The invention content is as follows:
the invention provides a fuel tank cap fatigue test bench for solving the problem that a repeated fatigue test device aiming at an automobile fuel tank cap is lacked in the prior art, and aims to solve the problems that the labor intensity of existing workers is high and the working efficiency is low.
The technical scheme adopted by the invention is as follows: a fuel tank cap fatigue test bed is composed of a fatigue test device, a U-shaped support and a base. The fatigue test device can simulate the situation that a person opens and closes the oil tank cap of an entity vehicle in actual life, and the requirements of different height positions of the oil tank caps of different vehicle types are met by adjusting the position of the sliding block on the U-shaped support. When the test is initial, the push rod is in an extending state, one end of the nylon rope is fixed on the oil tank cover of the solid vehicle, and the other end of the nylon rope is fixed on the unthreaded hole of the idler wheel. The electric cylinder data instruction in the oil tank cap fatigue test stand is given through the computer, the push rod contracts, the oil tank cap is stretched to a limit angle through the nylon rope, then the electric cylinder data instruction is given again through the computer, the push rod stretches out, and the oil tank cap is pressed through the idler wheel to be closed. After the reciprocating test, when the oil tank cover of the entity vehicle drops, the test stops. The invention has the advantages that: the operation is simple, the actual operation of workers is convenient, the working efficiency is improved, the reliability of the structure is high, and the damage is not easy to occur.
