Automatic detection and pressure test method and detection and pressure test device for automobile air cylinder

Abstract

The invention discloses an automatic detection and pressure test method and device for an automobile air reservoir, and the device comprises a guiding and conveying mechanism which comprises a guiding and conveying groove, the inner wall of the guiding and conveying groove is slidably connected with a plurality of guiding and conveying parts, and the air reservoir is slidably disposed in the guiding and conveying parts. The two sides of the guiding and conveying groove are each provided with a weighing unit used for weighing the air cylinder, the middle of the guiding and conveying groove is fixedly provided with a flaw detection unit used for conducting flaw detection on the surface of the air cylinder, and the other end of the guiding and conveying groove is fixedly provided with a detection pressure testing unit used for conducting pressure testing detection on the air cylinder. According to the invention, by arranging the guiding and conveying mechanism and the guiding and conveying piece, the air cylinder is continuously conveyed, the air cylinder is detected by utilizing the structures such as the pressure test detection unit and the weighing unit which are arranged on the conveying path, the automation degree of the equipment is high, and the detection speed is high.

Description

technical field [0001] The invention relates to the technical field of gas storage cylinder detection devices, in particular to an automatic detection and pressure test method and a detection and pressure test device for an automobile gas storage cylinder. Background technique [0002] The air storage tank is a gas storage device in the automobile braking system, which is used to store the gas compressed by the air compressor, and is used in automobile braking, whistle and other systems. [0003] Such as figure 1 Shown is an existing gas storage cylinder detection and pressure testing device, which is to put the detection liquid into the detection chamber, inflate the gas storage cylinder to a predetermined pressure, seal it and put it into the detection chamber, and the gas storage cylinder is controlled by the supporting rollers. The internal support is driven by the driving roller to rotate, and the air bubbles in the gas storage tank in the detection liquid are manually...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 Shown is an existing gas storage cylinder detection and pressure testing device, which is to put the detection liquid into the detection chamber, inflate the gas storage cylinder to a predetermined pressure, seal it and put it into the detection chamber, and the gas storage cylinder is controlled by the supporting rollers. The internal support is driven by the driving roller to rotate, and the air bubbles in the gas storage tank in the detection liquid are manually observed to determine whether the pressure resistance of the gas storage pump reaches the standard; the working continuity of this detection device is poor , the gas storage tanks can only be loaded and inspected one by one, and then unloaded one by one after completion, the detection efficiency is extremely low and labor-intensive; at the same time, there is no pre-structural inspection process for the gas storage tanks to be tested. For those with structural damage The gas storage tank was not removed before the test, and unnecessary pressure test tests were carried out, which further reduced the test efficiency
