[0002] Oil seals, as an important component in mechanical equipment, are mainly used to prevent the leakage of liquid media such as lubricating oil, ensure the normal operation of mechanical equipment and extend its service life. Oil seal detection usually involves visual inspection, dimensional measurement, performance testing and other aspects, aiming to ensure that the quality and performance of oil seals meet relevant standards. Oil seal detection is essential to ensure the reliability and safety of mechanical equipment. A poorly performing oil seal may cause leakage of lubricating oil, which will affect the normal operation of mechanical equipment. An oil seal detection tool is required to detect oil seals. The oil seal detection tool generally includes a fixing mechanism, a detection mechanism, a power mechanism and other auxiliary mechanisms.
