Abstract

The utility model relates to a device for testing the anti-vibration performance of a plastic fuel tank, belonging to the technical field of a fuel tank testing device. The device for testing the anti-vibration performance of the plastic fuel tank comprises a vibration testing table, the upper part of the vibration testing table is provided with a temperature testing tank capable of adjusting the temperature in the tank, the bottom of the temperature testing tank is provided with an opening, the vibration testing table can be covered by the temperature testing tank, the sidewall of the temperature testing tank is connected with a tank support frame and is supported on a lifting device through a box support frame, the lifting device is arranged under the box support frame, and the bottom of the lifting device is supported on a guide rail and can move along the guide rail. When the anti-vibration performance is tested at the set temperature, after a fuel tank simulating vehicle body device is fixed on the vibration testing table, the lifting device moves along the guide rail until the temperature testing tank is aligned with the vibration testing table, then the lifting device is lowered, the temperature testing tank falls correspondingly until the vibration testing table is covered, the temperature in the temperature testing tank is adjusted to the required temperature, and then the anti-vibration performance can be tested at the set temperature.

Description

Plastic fuel tank freedom from vibration pick-up unit

Technical field

The utility model relates to a kind of plastic fuel tank freedom from vibration pick-up unit, belongs to fuel tank pick-up unit technical field.

Background technology

Fuel tank of vehicle needs its anti-vibration performance of checking after manufacturing is finished.When checking fuel tank anti-vibration intensity, general way is at present, fuel tank is simulated body installation directly be fixed on the vibration table, regulates acceleration, vibration frequency, time, direction, carries out the freedom from vibration test.

With the method fuel tank is carried out the freedom from vibration test, can only detect the fuel tank anti-vibration performance under the temperature at place, test site, can't detect the anti-vibration performance of fuel tank under the specific environment temperature, thereby make the final testing result that obtains have limitation.

The utility model content

The purpose of this utility model is, overcomes problems of the prior art, and a kind of plastic fuel tank freedom from vibration pick-up unit is provided, and can carry out freedom from vibration to fuel tank under design temperature and detect.

For solving above technical matters, a kind of plastic fuel tank freedom from vibration pick-up unit provided by the utility model, the involving vibrations testing table, the top of described vibration table is provided with the temperature test chamber that can regulate the temperature inside the box, the bottom opening of described temperature test chamber and described vibration table can being covered, the sidewall of described temperature test chamber is connected with the case supports frame and is supported on the jacking gear by described case supports frame, described jacking gear is positioned at described case supports frame below, and the bottom support of jacking gear also can move along described guide rail on guide rail.

With respect to prior art, the utility model has been obtained following beneficial effect: when doing freedom from vibration at normal temperatures and detecting, fuel tank is simulated body installation directly be fixed on the vibration table and detect; In the time of need under design temperature, doing the freedom from vibration detection, fuel tank is simulated after body installation is fixed on the vibration table, jacking gear moves along guide rail and makes temperature test chamber aim at vibration table, jacking gear descends then, temperature test chamber falls thereupon, until vibration table is covered, regulate temperature test chamber again to the temperature that needs, can under design temperature, do freedom from vibration and detect; After finishing detection, jacking gear rises, and temperature test chamber is raised until leaving vibration table thereupon, and jacking gear moves horizontally along guide rail and leaves vibration table then.

Description of drawings

Fig. 1 is the structural representation of the utility model plastic fuel tank freedom from vibration pick-up unit.

Among the figure: 1 vibration table; 2 temperature test chambers; 3 case supports framves; 4 jacking gears; 5 guide rails.

Embodiment

As shown in Figure 1, the utility model plastic fuel tank freedom from vibration pick-up unit involving vibrations testing table 1, the top of vibration table 1 is provided with the temperature test chamber 2 that can regulate the temperature inside the box, the bottom opening of temperature test chamber 2 and vibration table 1 can being covered, the sidewall of temperature test chamber 2 is connected with case supports frame 3 and is supported on the jacking gear 4 by case supports frame 3, jacking gear 4 is positioned at case supports frame 3 belows, and the bottom support of jacking gear 4 also can move along guide rail 5 on guide rail 5.

When doing freedom from vibration at normal temperatures and detecting, fuel tank is simulated body installation directly be fixed on the vibration table 1 and detect; In the time of need under design temperature, doing the freedom from vibration detection, fuel tank is simulated after body installation is fixed on the vibration table 1, jacking gear 4 moves along guide rail 5 and makes temperature test chamber 2 aim at vibration table 1, jacking gear 4 descends then, temperature test chamber 2 falls thereupon, until vibration table 1 is covered, regulate the temperature of temperature test chamber 2 again to needs, can under design temperature, do freedom from vibration and detect; After finishing detection, jacking gear 4 rises, and temperature test chamber 2 is raised until leaving vibration table 1 thereupon, and jacking gear 4 moves horizontally along guide rail 5 and leaves vibration table 1 then.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.

Claims
