Problems solved by technology
[0003] The problem existing in the prior art is: due to the different models of the oil pressure shock absorber, the pressure test values of the joints of the oil pressure shock absorber are also different
When performing pressure tests on different types of hydraulic shock absorber joints, it is necessary to operate on presses with different pressures, which seriously affects production efficiency and increases the labor intensity of operators
If the oil pressure shock absorber joint is not pressure tested or the oil pressure shock absorber joint is leaked to do a pressure test, and when the qualified product is released and installed on the train, the oil pressure shock absorber joint will easily fall off, which will seriously affect the oil pressure damper. The overhaul quality of vibrator products affects the safe operation of vehicles

The invention discloses an oil damper joint pressure test device and a test method, which belong to the technical field of oil damper maintenance. The device comprises a rack; a supporting seat fixing device is arranged on the rack; the supporting seat fixing device comprises a piston rod lifting supporting seat and an oil storage tank lifting supporting seat arranged at two sides of the rack; the middle of the rack is provided with a press device; and each of the piston rod lifting supporting seat and the oil storage tank lifting supporting seat comprises a threaded rod transmission device and a supporting seat fixing device. According to the oil damper joint pressure automatic test device, different pressures of the press can be controlled through a man-machine operation interface to perform pressure test on piston rod ring joints and oil storage tank ring joints of different types of dampers.
Description
technical field [0001] The invention relates to pressure testing equipment and a testing method for an oil pressure shock absorber joint, belonging to the technical field of oil pressure shock absorber maintenance. Background technique [0002] With the rapid development of high-speed trains, there are higher requirements for the stability and safety of vehicle operation. The hydraulic shock absorber is one of the important components to reduce the vibration of the vehicle and improve the smooth and safe operation of the vehicle. When the hydraulic shock absorber is overhauled, the piston rod ring joint and the oil storage cylinder ring joint need to be replaced by pressing out. When replacing with a new joint, it is necessary to perform a pressure test on the piston rod ring joint and the oil storage cylinder ring joint. , the components of the oil shock absorber can only be assembled after the pressure test is qualified. [0003] The problem existing in the prior art is:...
