Description

Technical Field

[0001] The utility model relates to the field of oil seal press-fitting, in particular to a rapid oil seal press-fitting device. Background Art

[0002] In many mechanical equipment, liquids or lubricants are essential because they contribute to the normal operation and maintenance of the equipment. Oil seals play a key role in this regard, effectively preventing liquids or lubricants from leaking and maintaining the cleanliness of the equipment and the normal working environment.

[0003] In addition, oil seals also play an important role in preventing dust, dirt and other impurities from entering mechanical parts, thereby extending the service life of the equipment and reducing maintenance costs. Especially for key components such as bearings and joints, oil seals ensure that they are in good working condition, further improving the reliability and stability of the equipment, reducing failures and downtime, and thus improving production efficiency.

[0004] For example, Chinese patent No. CN218225405U discloses an oil seal pressing tool. The oil seal pressing tool can compensate to a certain extent for the axial upward movement of the pressed end face of the oil seal outer ring after the oil seal pressing tool is removed as the component with interference fit is reset, thereby improving the sealing effect of the oil seal.

[0005] However, the device requires manual operation. During the manual operation of press-fitting oil seals, it is impossible to ensure that each oil seal is accurately press-fitted during the processing, which will cause a certain degree of damage to the oil seal. In addition, since the mold of the device adopts a fixed size, it is impossible to press-fit oil seals of different specifications, which affects the normal press-fitting of the oil seals and causes a decrease in work efficiency, and the scope of use is limited.

[0006] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
