Description
Technical Field
The invention relates to the technical field of automobiles, in particular to a fuel pump vibration clamp and a using method thereof.
Background
With the rapid development of the automobile industry in China, the automobile detection kit is developed along with the market demand. According to the development of the market, the detection business of the automobile parts also begins to expand and grow along with the market. The chassis parts such as the automobile fuel pump (hereinafter, collectively referred to as a sample) in the parts are important automobile parts, and are nozzles of engines, so that the automobile has stable and strong power. The direct reason why 559882 cars have been recalled by several car manufacturers in recent years is the fuel pump, which recall reason: due to the design and manufacture reasons of a certain part supplier, the oil return pipe bracket of the fuel pump flange of the vehicle in the recall range may crack, so that fuel oil leakage is caused, and potential safety hazards exist. The improved fuel pump is freely replaced for vehicles within the recall range of the automobile manufacturers, so that potential safety hazards are eliminated.
Therefore, the fuel pump not only meets the environmental use requirement in the structural process design of the fuel pump in the research and development stage, but also meets various comprehensive environmental stress requirements in the quality and performance detection process before products are on the market. Before this, because the national standard and various standards lacked in the aspect of testing relevant mechanical environment stress, basic mechanical environment simulation test was not carried out, resulting in quality accidents, so that automobile part suppliers put more and more importance on the mechanical environment simulation test of the fuel pump, and because the mechanical environment simulation test of the fuel pump needs the actual installation state of the simulation test, the installation clamp needed by the test needs to be customized.
More than 95% of the existing tests are cylindrical vertical installation, the existing installation clamp comprises two clamps with M-shaped structures and two semicircular thick clamps, and the simulation test of the sample is realized through the matching of the two parts. Specifically, two semicircular thick hoops are adopted to clamp the middle position of the fuel pump, and then the two semicircular thick hoops and the fuel pump are installed on two clamps which are formed by combining an M-shaped structure. Because the existing semicircular thick clamp is usually designed according to a single sample and cannot be correspondingly designed according to each sample, the semicircular thick clamp of the sample basically only can meet the installation requirement of the single sample. And adopt the same sample anchor clamps centre gripping fuel pump to have the problem: 1) the phenomenon of clamping and rotating of the fuel pump can occur when the fuel pump is installed on a clamp; 2) the fuel pump is not clamped by the clamp after being installed on the clamp, and the loosening phenomenon exists.
The analysis causes the main reason of fuel pump anchor clamps clamping mode defect:
1) the inner diameter of the semicircular thick clamp is fixed, while the outer diameters of fuel pumps in different batches are changed, and when the outer diameter of the fuel pump is larger than the inner diameter of the semicircular thick clamp, the fuel pump can be clamped and rotated;
2) when the outer diameter of the fuel pump is smaller than the inner diameter of the thick hoop, the fuel pump can be clamped loosely; the clamped part of the fuel pump is the middle part of the fuel pump shell (weak part on the shell), and the clamping deformation of the shell and the clamping of the internal parts are another main reason for clamping and rotating the fuel pump.
