Fuel tank tightness detecting device

Abstract

The invention provides a fuel tank tightness detecting device belonging to the technical field of machinery. The fuel tank tightness detecting device is used for solving the problem that a fuel tank tightness detecting device does not exist and comprises a bottom plate and a ventilation mechanism communicated with a fuel tank, an opened water tank is arranged on the bottom plate, a propping-pressing component propping against the fuel tank is arranged above the opening of the water tank, and a driving piece capable of driving the propping-pressing component to move so as to drive the propping-pressing component to press the fuel tank into water is arranged between the propping-pressing component and the bottom plate. The fuel tank tightness detecting device has the advantages of suitability of detecting various fuel tanks, convenience and rapidness, is flexible to use and is simple to operate.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a detection device, in particular to a fuel tank tightness detection device. Background technique [0002] A fuel tank is a container for oil. It is an essential part of fuel vehicles. The safety of the fuel tank directly affects the safety of the vehicle; therefore, all countries have formulated standards for the safety performance requirements and test methods of the fuel tank. For example, "GB18296-2001 Automobile Fuel Tank Safety Performance Requirements and Test Methods" formulated by the People's Republic of China and the People's Republic of China Automobile Industry Standard "QCT 644-2000 Technical Conditions for Automobile Metal Fuel Tanks", through the formulation of mandatory standards for automotive fuel tanks Improve the design and manufacture quality of fuel tanks, reduce environmental pollution, and reduce casualties and vehicle damage caused by fuel tank damage ...

AI Technical Summary

Problems solved by technology

[0003] At present, although there are national standards and industry standards, fuel tank manufacturers and automobile assembly plants generally can only conduct sampling inspections. The inspection method is that the inspector presses the fuel tank sideways into the water. There are following defects: after the fuel tank is flushed into the air, the buoyancy is relatively large, so the inspector must be a relatively strong person, and at the same time, there will still be a problem of high labor intensity; There is a certain risk to health; due to manual operation, some areas may not be submerged in water or the depth is not enough, resulting in inaccurate test results

The main reason for the above defects is that there is no detection device for detecting the tightness of the fuel tank
