Abstract
The technical scheme adopted by the invention is as follows: a fatigue test bed for a fuel tank cover consists of a fatigue test device, a U-shaped bracket and a base. The fatigue test device can simulate the situation that a person opens and closes the fuel tank cap of the entity vehicle in actual life, and meets the requirements of different height positions of the fuel tank caps of different vehicle types by adjusting the position of the sliding block on the U-shaped bracket. At the beginning of the test, the push rod is in an extending state, one end of the nylon rope is fixed on the fuel tank cover of the solid car, and the other end is fixed on the unthreaded hole of the roller. The electronic cylinder data instruction in the fatigue test bed of the fuel tank cap is given by a computer, the push rod contracts, the fuel tank cap of the entity vehicle is stretched to a limit angle by a nylon rope, then the electronic cylinder data instruction is given by the computer again, the push rod extends out, and the fuel tank cap of the entity vehicle is pressed by the roller to be closed. After the reciprocating test, when the fuel tank cap of the entity vehicle falls, the test is stopped.
Description
Technical field:
The invention relates to a lifting type fuel tank cap fatigue test bed, in particular to a repeated fatigue test for a fuel tank cap of an automobile, and belongs to the field of engineering machinery.
The background technology is as follows:
In modern traffic development, the automotive industry is rapidly developing, and the safety performance of automobiles is very important for drivers and social security. The fatigue test for the automobile parts can judge whether the automobile parts accord with the national standard, and the fatigue test is carried out by people to open and close the oil tank cover in a reciprocating way, so that the labor intensity of workers is increased, and the working efficiency is low. In view of this, a lift-type fuel tank cap fatigue test stand is urgently needed in the industry.
The invention comprises the following steps:
The invention provides a fatigue test stand for an automobile fuel tank cap, which aims at solving the problem that the prior art lacks a repeated fatigue test device for the automobile fuel tank cap and solves the problems of high labor intensity and low working efficiency of the existing staff.
The technical scheme adopted by the invention is as follows: a fatigue test bed for a fuel tank cover consists of a fatigue test device, a U-shaped bracket and a base. The fatigue test device can simulate the situation that a person opens and closes the fuel tank cap of the entity vehicle in actual life, and meets the requirements of different height positions of the fuel tank caps of different vehicle types by adjusting the position of the sliding block on the U-shaped bracket. At the beginning of the test, the push rod is in an extending state, one end of the nylon rope is fixed on the fuel tank cover of the solid car, and the other end is fixed on the unthreaded hole of the roller. The oil tank cover fatigue test bench is given by a computer, the oil tank cover is stretched to a limit angle through a nylon rope by means of contraction of a push rod, then the oil tank cover is closed by means of pushing the oil tank cover by means of pushing the push rod through a roller after the computer gives the oil tank data command again. After the reciprocating test, when the fuel tank cap of the entity vehicle falls, the test is stopped. The invention has the advantages that: the operation is simple, the practical operation of staff is convenient, the working efficiency is improved, the reliability of the structure is high, and the damage is not easy to occur.
