Abstract

The invention relates to an automobile oil filter air tightness test automation device and a test method thereof. A positioning detecting assembly is used to position and detect a workpiece to be detected. A pressing assembly is used, and in particular pressure generated by a gas-liquid boosting cylinder is used to press the workpiece to be detected. A spring pressure head assembly contacts the upper surface of the workpiece to be detected. A side plate hole of the workpiece is plugged by a plugging cylinder. A vent hole in the upper surface of the workpiece is plugged by a plugging head. An ATEQF620 air tightness leak detector is connected with a test tube connector for air tightness testing. The gas-liquid boosting cylinder can generate predetermined downforce to ensure the plugging effect. A sealing ring which matches the contour of the workpiece to be detected is arranged on a positioning detecting seat. The sealing ring can ensure that no gap is between the lower surface of the workpiece to be detected and the positioning detecting seat. The plugging effect is further enhanced. A sliding assembly, the positioning detecting assembly and the pressing assembly match each other, so that the overall device has the advantages of high motion continuity and high efficiency.

Description

technical field [0001] The invention relates to air tightness testing equipment, in particular to an automatic equipment for testing the air tightness of an automobile engine oil filter and a testing method thereof. Background technique [0002] Automotive oil filter, referred to as "steam filter", the main function of the steam filter is to filter out impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine. Under normal circumstances, the various components in the engine are lubricated by engine oil to achieve normal work, but metal debris, dust entering, carbon deposits oxidized at high temperatures, and some water vapor generated during the operation of the components will continue to mix into the engine. In the engine oil, the service life of the engine oil will be reduced after a long time, and it may affect the normal operation of the engine in severe cases. Therefore, the quality of the automobile oil filter direct...
