A device for detecting oil leakage of automobile bridge box parts

Abstract

The invention discloses an oil seepage detection device for parts of an automobile bridge box, which relates to the technical field of automobile parts detection, and comprises a base, and a support seat and a transparent detection box are respectively fixedly installed on both sides of the top outer wall of the base. The top of the support seat is provided with a circulating mixing assembly; the present invention uses a warm water supply pipe to flow warm water into the transparent detection box. When there is a penetration point, the pigment will ooze out from the test part and quickly dissolve in the penetration point. In the water, it can cause rapid local color changes in the water, thereby facilitating the detection of penetration points; at the same time, the continuous water supply of the warm water supply pipe can cooperate with the pumping effect of the liquid outlet pipe, so that the warm water can achieve stable and continuous lateral flow under the action of the diversion horizontal plate , when infiltration occurs, the pigment continues to ooze out at the infiltration point. Under the action of the lateral flow of water, a ribbon-shaped water flow starting from the infiltration point can appear, so that the inspector can observe the infiltration position conveniently.

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
