Description

Technical Field

[0001] The utility model relates to the technical field of linear guide rail end covers, in particular to a high-lubrication multifunctional linear guide rail slider end cover. Background Art

[0002] Linear guides are a type of rolling guide. When in use, the steel balls mainly roll and circulate infinitely between the slider and the guide rail, allowing the load channel to easily perform high-precision linear motion along the guide rail. The friction coefficient can be reduced to 1 / 50 of that of traditional sliding guides, making it easy to achieve μm positioning accuracy.

[0003] The linear guide's end unit design between the slider and the guide rail enables it to withstand loads in all directions, including up, down, left, and right. The linear guide assembly is lubricated via end caps located at both ends of the slider's axis. The lubrication channels in the end caps, combined with the linear guide assembly's return system and simplified structural design, ensure smooth, low-noise motion.

[0004] Lubricating oil in guide rails is typically added through the oil nipple in the end cap. However, when adding lubricating oil through the oil passages on existing end caps, the lubricating oil cannot be quickly and evenly distributed on the guide rail surface. This results in insufficient and inadequate lubrication of the guide rail surface, which can easily damage the guide rail surface. This can also affect the accuracy of the guide rail surface during long-term operation, resulting in a short maintenance cycle. Therefore, it is necessary to provide an end cap that can ensure that the guide rail surface receives a constant, quantitative, and evenly distributed lubrication, thereby improving the surface accuracy and service life of the guide rail. To this end, we propose a high-lubrication, multifunctional linear guide slider end cap to address these technical issues. Utility Model Content

[0005] The purpose of the utility model is to solve the technical problems that when lubricating oil is added to the oil channel on the existing end cover, the lubricating oil cannot be quickly and evenly distributed on the guide rail surface, resulting in the guide rail surface not being effectively and fully lubricated, easily damaging the guide rail surface, the accuracy of the guide rail surface cannot be guaranteed during long-term operation, and the maintenance cycle is short. A high-lubrication multifunctional linear guide slider end cover is provided to solve the above technical problems.
