Oil leakage detection apparatus for automobile gap bridge box parts

Abstract

The invention discloses an oil leakage detection apparatus for automobile gap bridge box parts and relates to the technical field of automobile part detection. The oil leakage detection apparatus comprises a base, two sides of the outer wall of the top of the base are respectively and fixedly provided with a supporting seat and a transparent detection box, and the top end of the supporting seat is provided with a circulating mixing assembly; warm water can flow into the transparent detection box through the warm water supply pipe; when a permeation point exists, pigment seeps out of the test component and is rapidly dissolved in water at the permeation point, local color change can be rapidly generated in water, and then the permeation point can be conveniently detected; meanwhile, continuous water supply of the warm water supply pipe can be matched with the water pumping effect of a liquid outlet pipe, so that stable and continuous transverse flowing of warm water is achieved under the effect of a flow guide transverse plate, when permeation occurs, pigment continuously seeps out at permeation points, and under the effect of transverse flowing water flow, color-strip-shaped water flow with the permeation points as the starting point can appear; therefore, the detection personnel can conveniently observe the permeation position.

Description

technical field [0001] The invention relates to the technical field of auto parts detection, in particular to an oil seepage detection device for parts of an automobile bridge box. Background technique [0002] The bridge box cover is an important part of the drive axle of wheeled tractors and heavy-duty vehicles. Defects such as shrinkage porosity, shrinkage cavity, lack of meat, sarcoma, etc., defects will cause oil leakage in the parts of the bridge box cover during work, resulting in insufficient lubrication of the vehicle transmission mechanism, accelerating the mechanical wear of various parts and reducing the service life . Therefore, during the production of automobile bridge box parts, oil leakage detection is required. [0003] The Chinese invention patent with the publication number CN111380654A is an oil leakage detection device for bridge box parts, including four parts: mechanical structure, hydraulic system, air pressure system, and control system. The mecha...

Problems solved by technology

[0004] However, the above-mentioned invention has the following disadvantages: when the above-mentioned patent detects, it mainly relies on the enhancement of the internal air pressure, and uses a strong light flashlight to check whether there is bubbles. The specific phenomenon is not particularly obvious. It is difficult to quickly judge the penetration position; in addition, the external water itself may generate air bubbles, which will affect the accuracy of the detection personnel's judgment, so there are certain limitations
