Description

Technical Field

[0001] The utility model relates to the technical field of rubber oil seal processing, in particular to a precise trimming device for a rubber oil seal. Background Art

[0002] Oil seal is a common name for general seals, which simply means the seal of lubricating oil. It is a mechanical component used to seal grease (oil is the most common liquid substance in the transmission system, and also refers to general liquid substances). It isolates the parts that need lubrication from the output parts in the transmission parts to prevent the lubricating oil from leaking. The seals used for static seals and dynamic seals (generally reciprocating motion) are called oil seals. After the production of oil seals, the burrs of the oil seals need to be trimmed by a trimming device.

[0003] After searching, the patent publication number CN219563384U discloses a rubber oil seal trimming device, which adjusts the rotation radius of the trimming knife by setting an adjustment mechanism, and can trim oil seals with different radii, thereby improving the practicability and working efficiency of the device. However, when the oil seal is fixed, the fixed disk is relatively flat. When the oil seal is placed on the fixed disk for fixing, it is difficult to ensure that the oil seal is in the center position of the fixed disk. When the oil seal rotates, the trimming knife is likely to cut the oil seal, thereby easily causing damage to the oil seal, which not only increases the production cost of the oil seal, but also reduces the production efficiency.
