[0001] The utility model relates to the technical field of machinery, in particular to a self-cleaning linear guide rail. Background Art

[0002] In the fields of mechanical processing, automation equipment and precision manufacturing, linear guides are important linear motion components, and their performance and precision directly affect the operating efficiency and product quality of the equipment. During the operation of existing linear guides, especially in construction sites, dust and impurities will inevitably accumulate on the surface of the guides. These impurities adhere to the guides for a long time, which will not only affect the accuracy and stability of the guides, but also pose a potential threat to the normal operation of the equipment.

[0003] China Utility Model Announcement No.: CN220845000U discloses a self-cleaning linear guide rail, including a base, a track, a slide, a cleaning component, a connecting rod and a lubrication component. The solution is that the slide moves linearly along the track, and at this time the cleaning component sweeps away the dust on the outer side walls of the upper and lower guide rails to prevent dust accumulation from affecting the use of the track. After the linear guide rail has been used for a period of time, the lubrication component is closely attached to the outer side walls of the upper and lower guide rails, which is convenient for oiling the upper and lower guide rails, thereby lubricating the track and preventing the guide rails from being worn and rusted. It is practical, convenient and easy to operate.

An oil storage cotton installation groove 15 is opened on the outer side of the first sliding block 3 for installing the first oil storage cotton 11. With the movement of the sliding block, the first oil storage cotton 11 will gradually release lubricating oil, thereby playing a role in lubricating the surface of the first guide rail 2. The surface of the oil storage cotton installation groove 15 is also provided with penetration holes 16. These holes allow the lubricating oil to seep out of the first oil storage cotton 11, thereby providing lubrication for the contact surface between the first guide rail 2 and the first sliding block 3 and the second sliding block 8.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A limiting groove 19 is provided on the front end outer wall of the first guide rail 2, and a limiting hole 12 is provided at the connection between the first buckle cover 4 and the first slider 3. The limiting holes 12 are located on both sides of the outside of the first buckle cover 4. By combining the design of the limiting groove 19 and the limiting holes 12, the accurate installation, positioning and sliding of the slider on the guide rail are ensured, while reducing maintenance costs and increasing service life.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A fixing hole 14 is also provided at the connection between the first buckle cover 4 and the first slider 3. The fixing hole 14 is located on the outer wall of the limiting mounting groove 13. The fixing hole 14 firmly fixes the first buckle cover 4 to the first slider 3 through the fixing screw 7, thereby enhancing the connection strength between the two and preventing the first buckle cover 4 from accidentally loosening or falling off during use.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The first guide rail 2 is slidably connected to the first slider 3 and the second slider 8. The second slider 8 is located below the first slider 3. The first slider 3 and the second slider 8 are U-shaped structures. The first slider 3 and the second slider 8 are U-shaped structures, which can reduce the accumulation of dust and impurities, and the U-shaped structure design makes the contact area between the slider and the guide rail larger, thereby improving the sliding stability and load-bearing capacity.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The first slider 3 is fixedly connected with the limited installation groove 13 on both sides of the outside, and the limited teeth 6 are fixedly arranged at the connection between the first slider 3 and the first guide rail 2. The limited teeth 6 and the limited slide groove 19 are slidably connected.

The fixing screw 7 is tightly combined with the limited hole 12 and the fixing hole 14 through the thread, ensuring that the first buckle cover 4 is firmly fixed on the first slider 3, and can prevent the buckle cover from loosening or falling off due to vibration or external force during use. The first brush 10 is arranged on the side where the penetration hole 16 is in contact with the first guide rail 2. By arranging the first brush 10 on the side where the penetration hole 16 is in contact with the first guide rail 2, the cleaning effect, lubrication effect and precision of the self-cleaning linear guide can be significantly improved.

[0037] The implementation principle of the utility model is:

[0038] First, fix the first guide rail 2 on the guide rail base 1 to ensure that the first guide rail 2 is stable and horizontal, and then place the first slider 3 and the second slider 8 on the first guide rail 2 so that they can slide freely along the first guide rail 2. At this time, the limiting teeth 6 of the first slider 3 and the second slider 8 cooperate with the limiting slide groove 19 of the first guide rail 2 to ensure stability during the sliding process. Place the first oil storage cotton 11 in the oil storage cotton mounting groove 15 of the first slider 3 and the second slider 8, and use the first buckle cover 4 to close it through the buckle cover mounting groove 18.

[0039] Secondly, the first buckle cover 4 is fixed on the limiting installation groove 13 by passing the fixing screw 7 through the limiting hole 12 and the fixing hole 14, ensuring the stable installation of the first oil storage cotton 11, and cooperating with the sealing rib (17) to prevent the lubricating oil of the first oil storage cotton 11 from leaking outward, thereby increasing the service life of the first oil storage cotton 11. Due to the setting of the oil storage cotton installation groove 15 and the penetration hole 16, the lubricating oil can gradually seep out to the first brush 10. As the first slider 3 and the second slider 8 slide on the first guide rail 2, the first brush 10 evenly applies the lubricating oil on the surface of the first guide rail 2 to achieve a lubricating effect.

[0040] Then, during the sliding of the first slider 3 and the second slider 8, the first reverse teeth 5 protruding on their outer sides will contact the surface of the first guide rail 2 to clean the dirt and impurities on the surface. At the same time, the first forward teeth 9 recessed on the inner sides of the first slider 3 and the second slider 8 avoid scraping off the lubricating oil applied by the first brush 10, thereby ensuring the durability of the lubrication effect.

[0041] Finally, as the use time increases, the lubricating oil in the first oil storage cotton 11 will gradually decrease. At this time, the first buckle cover 4 can be disassembled to replace the first oil storage cotton 11 with a new one.

[0042] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
