Problems solved by technology

The oil seepage detection of the bridge box cover is realized by water inspection and bubbling. The box cover is sealed and filled with high-pressure gas, and the whole is submerged in water to check whether there are bubbles coming out of the parts. If there are bubbles, it means that there are casting defects inside the parts. There will be oil leakage in the bridge, and the parts are unqualified

Abstract

An oil leakage detection device for bridge box parts comprises a mechanical structure, a hydraulic system, an air pressure system and a control system, and the mechanical structure comprises a rack, aworkbench, stand columns, a cross beam, a linear sliding rail, a water tank and a sealing cover; the hydraulic system comprises a first hydraulic cylinder, a second hydraulic cylinder and a third hydraulic cylinder. The air pressure system comprises an air pump. An overflow valve, an electromagnetic reversing valve, a throttle valve and the like; the control system comprises a PLC control system,an electromagnetic reversing valve, a motor and a hydraulic pump. According to the system, the PLC control system is adopted to control the hydraulic and pneumatic system to complete a specific working stroke so as to achieve automatic oil leakage detection tasks of the bridge box cover parts, and the hydraulic and pneumatic system serves as an execution unit to drive the mechanical equipment workbench to ascend and descend, the parts to be clamped and loosened and the parts to be inflated and deflated. According to the system, the oil leakage detection efficiency of the bridge box part is effectively improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of bridge boxes, in particular to a device for detecting oil seepage of bridge box components. 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 . It is an important link to ensure product quality and production safety to test the air tightness of the bridge box cover by simulating the oil pressure of the rear axle of the truck transmission. The oil seepage detection of the bridge box cover is realized by water inspection and bubbling. The box cover is sealed and filled with high-pressure gas, and the whole is submerg...
