Automotive fuel tank exhaust valve testing equipment

Abstract

The invention discloses a vehicle's fuel tank exhaust valve detection device, which relates to a vehicle part manufacturing and detecting device and more particularly, to a vehicle's fuel tank exhaust valve detection device. The device comprises a machine frame, an impact testing mechanism, a performance testing mechanism, a state display light, and a wind discharge fan. The state display light and the wind discharge fan are arranged on the top of the machine frame. The impact testing mechanism and the performance testing mechanism are arranged inside the machine frame. The machine frame is built by aluminum section profiles in an 80X80 mm size. The bottom of the machine frame is provided with a lockable pin wheel. The back of the machine frame is provided with an air channel control cabinet. The front surface of the machine cabinet is provided with a pull-and-push door controlled by an electromagnetic security switch. According to the invention, required by the system functions of the fuel tank, the technical requirements and testing codes for the working air discharge valve are defined so that they can be applied to the development and purchase work of the device. In addition, the device is further provided with error prevention and sound-and-light alarming functions. The configured human-machine interface makes human-machine exchange more convenient.

Description

technical field [0001] The invention relates to a production testing device for auto parts, in particular to a testing device for an exhaust valve of an automobile fuel tank. Background technique [0002] At present, the reading of data on the existing test equipment still adopts the method of manually reading the pointer dial. Due to the influence of pointer friction, vibration, deformation and manual reading accuracy, this method results in a large error in the obtained data, which affects the test. precision. In addition, the existing equipment is relatively simple, and usually can only guarantee a single characteristic of the product tested by a single equipment. After the test is completed, the product needs to be taken out to another test equipment for other performance tests. In this way, the product will inevitably be affected by the environment during the process of being taken out and put in many times, resulting in low test accuracy, cumbersome test process, labo...

[0002] At present, the reading of data on the existing test equipment still adopts the method of manually reading the pointer dial. Due to the influence of pointer friction, vibration, deformation and manual reading accuracy, this method results in a large error in the obtained data, which affects the test. precision

In addition, the existing equipment is relatively single, usually only a single device can be guaranteed to test a single characteristic of the product. After the test is completed, the product needs to be taken out to another test device for other performance tests

In this way, the product will inevitably be affected by the environment during the process of being taken out and put in many times, resulting in low test accuracy, cumbersome test process, labor-intensive, and low efficiency.
