Aerated detector of damper of oil seal type

Abstract

The invention relates to an aerated detector of a damper of an oil seal type. The detector adopts hydraulic and pneumatic driving technologies, a left air chamber clamping damper and a right air chamber clamping damper are driven by a hydraulic cylinder so as to form a closed air chamber space at the aerated part of the damper; the aerated gas circuit of the two air chambers is controlled by an aerated valve to switch on or off; and gases (special gases) required by the process are aerated into a damper gas storage chamber by an air needle. A pneumatic detection device is arranged above, and the pressure head of the device is arranged to be lower than the highest part of the popping connecting rod of the damper and higher than the lowest part of the compressed connecting rod of the damper so that the connecting rod is blocked by the pressure head and can not be fully popped, and the counter force value of the connecting rod of the damper is reversely measured. The whole motion process can be automatically controlled by utilizing the programming of a PLC (Programmable Logic Controller), and the pre-pressure distance of the pressure head can be solely set. The detector is designed and produced according to the practical production conditions of a current damper industry and can meet the assembly need of main dampers in domestic markets, thereby being unnecessary special equipment for the special production of aerated dampers.

Description

technical field [0001] The invention relates to an inflator, in particular to an oil-sealed shock absorber inflation detection machine for inflating a gas-inflatable shock absorber and detecting the inflation rebuttal force of a connecting rod of the shock absorber. Background technique [0002] The shock absorber inflator is specially designed for the gas-filled shock absorber inflation process. Since the inflation process of the pneumatic shock absorber is a newly added production process in the industry, the shock absorber manufacturers do not have complete inflation equipment, and some of them make a simple inflation mold by themselves, which not only cannot keep up with the production rhythm, but also has a low pass rate. Air source waste rate is high. Some equipment is introduced, but it is not easy to use, such as the clamp arm type inflator, its clamping mold is particularly easy to break, and it is inconvenient to maintain.

AI Technical Summary

Problems solved by technology

Since the inflation process of the pneumatic shock absorber is a newly added production process in the industry, the shock absorber manufacturers do not have complete inflation equipment, and some of them make a simple inflation mold by themselves, which not only cannot keep up with the production rhythm, but also has a low pass rate. Gas source waste rate is large

Some of them are imported equipment, but they are not easy to use. For example, the clamp arm type inflator, its clamping mold is particularly easy to break, and it is inconvenient to maintain.
