Problems solved by technology

[0002] In order to ensure the sealing performance of the brake wheel cylinder, a tightness test is required. The existing tightness tests are mostly static, that is, the product remains stationary during the test. In this way, the test can only meet the tightness test of one state of the product, and cannot be tested. The tightness of the product in the working stroke

Abstract

The invention discloses a brake wheel cylinder working stroke sealing performance test system, comprising: a rack, comprising an upper mounting plate and a bottom plate arranged up and down, and a vertical column vertically arranged between the upper mounting plate and the bottom plate, and the bottom plate being provided with a positioning seat used for positioning a brake wheel cylinder; a downward pressing mechanism, comprising a downward pressing driver, a sliding plate and a pressing head connected with the sliding plate, the downward pressing driver being installed on the upper installation plate, and the downward pressing driver driving the sliding plate to move downwards and driving the pressing head to press the brake wheel cylinder; a piston jacking and moving mechanism, comprising a transverse moving assembly and a clamping assembly, the transverse moving assembly being connected with the sliding plate and moving downwards synchronously along with the sliding plate, and theclamping assembly being driven by the transverse moving assembly to move transversely; and a detection mechanism, comprising an inflation pipe and a low-pressure leak detector, and the low-pressure leak detector inflating and stabilizing the pressure in the piston cavity of the brake wheel cylinder through the inflation pipe and detects the leakage value. According to the invention, the sealing performance of the brake wheel cylinder in the working stroke can be tested.

Description

technical field [0001] The invention relates to a brake wheel cylinder detection technology, in particular to a dynamic sealing performance detection device for a brake wheel cylinder assembly. Background technique [0002] In order to ensure the sealing performance of the brake wheel cylinder, a sealing test is required. Most of the existing sealing tests are static, that is, the product remains stationary during the test. In this way, the test can only meet the sealing test of one state of the product, and cannot be tested. The tightness of the product in the working stroke. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a brake wheel cylinder working stroke tightness test system, which can test the tightness of the product in the working stroke. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a brake wheel cylinder working stroke sealin...
