In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides an oil blanket seal lip fat liquoring frock, includes barrel and pressure axle, one end opening is sealed to barrel one end, the outer wall of barrel cooperatees with the seal lip of oil blanket, the pressure axle cooperation is located in the hole of barrel, there are a plurality of through-holes along the circumference equipartition on the outer wall of barrel, the through-hole intercommunication the inside and outside both sides of barrel.
When the tool is used, lubricating grease is injected into the cylinder, the pressing shaft is inserted into the cylinder, then the oil seal is sleeved on the outer wall of the cylinder, the axial position of the oil seal is adjusted to enable the sealing lip to be aligned with the through hole of the outer wall of the cylinder, and the lubricating grease in the cylinder overflows into the sealing lip from the through hole by pushing the pressing shaft to move inwards, so that a plurality of lubricating grease points are uniformly formed on the circumference of the sealing lip.
As a preferable scheme of the utility model, the distance from the center of the through hole to the lower end of the cylinder is the same as the distance from the center of the sealing lip of the oil seal to the lower side surface of the oil seal. By adopting the technical scheme, the lower side of the oil seal is placed on the workbench, the cylinder body is inserted into the oil seal, the lower end of the cylinder body is in contact with the workbench, and the through hole on the cylinder body can be directly aligned with the center of the sealing lip of the oil seal without adjusting the position of the oil seal in the axial direction of the cylinder body, so that the whole greasing operation is simpler and more convenient.
As a preferable scheme of the utility model, the lowest part of the through hole is attached to the bottom wall of the inner hole of the cylinder body. The arrangement is such that grease in the bore of the barrel can be pushed out entirely.
As a preferable scheme of the utility model, the lower end of the pressing shaft is provided with an inverted inclined plane. Through setting up the chamfer, make it have the guide effect to the convenience is inserted the pressure axle in the barrel hole.
As the preferable scheme of the utility model, the opening part of the inner hole of the cylinder body is provided with the inverted right angle, so that the insertion of the pressing shaft is facilitated, and the scraping of the outer wall of the pressing shaft is avoided.
As a preferable scheme of the utility model, the lower end of the cylinder body is provided with a rounding angle. The lower end of the cylinder body is rounded to form smooth transition, so that the sealing lip is prevented from being damaged when the oil seal is sleeved into the cylinder body.
In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:
when the tool is used, lubricating grease is injected into the cylinder, the pressing shaft is inserted into the cylinder, then the oil seal is sleeved on the outer wall of the cylinder, the axial position of the oil seal is adjusted to enable the sealing lip to be aligned with the through hole of the outer wall of the cylinder, and the lubricating grease in the cylinder overflows into the sealing lip from the through hole by pushing the pressing shaft to move inwards, so that a plurality of lubricating grease points are uniformly formed on the circumference of the sealing lip.

Detailed Description
The present utility model will be described in detail with reference to the accompanying drawings.
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Examples
The embodiment provides an oil seal lip greasing tool;
as shown in fig. 1 and 2, the oil seal lip greasing tool in this embodiment includes a cylinder 1 and a pressing shaft 2, one end of the cylinder 1 is closed, one end of the cylinder is opened, the outer wall of the cylinder 1 is matched with the sealing lip of the oil seal 3, the pressing shaft 2 is matched with and arranged in the inner hole of the cylinder 1, a plurality of through holes 4 are uniformly distributed on the outer wall of the cylinder 1 along the circumference, and the through holes 4 are communicated with the inner side and the outer side of the cylinder 1.
