[0003] Some existing abrasion-resistant self-lubricating coating devices for the surface of robot bearings cannot automatically add lubricating oil to the bearings. If the device cannot automatically add lubricating oil, regular lubrication operations are required. In large-scale robot application scenarios or when the working intensity of the machine is relatively high, this means a large amount of human input. There are numerous robot devices in an automated factory, and adding lubricating oil one by one will consume a large amount of time and labor costs. Therefore, an abrasion-resistant self-lubricating coating device for the surface of a robot bearing is proposed to solve the above problems. Summary of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0031] Referring to Figure 1 , Figure 3 , an embodiment provided by the present utility model: A wear-resistant self-lubricating coating device for the surface of a robot bearing includes a main body 1. The main body 1 is made of high-strength alloy steel, which has good strength and toughness and can withstand various forces during the operation of the bearing, ensuring the structural stability of the entire device. The inner part of the main body 1 is rotatably connected with a first rotating ring 2. The surface of the first rotating ring 2 is finely polished, and its smooth surface can effectively reduce the friction with the ball 3, ensuring the smoothness of rotation;
[0032] Inside the rotating ring 1-2, a plurality of balls 3 are rotatably connected. The balls 3 are made of high-hardness ceramic material, which has high hardness and strong wear resistance, can be used for a long time in a high-load working environment, and greatly extends the service life of the bearing. Both the upper and lower ends of the balls 3 are rotatably connected to the outer shell 4. The outer shell 4 is made of lightweight aluminum alloy material, which reduces the overall weight while ensuring a certain strength. The oil storage tank inside it can store an appropriate amount of lubricating oil, providing a stable oil source for the lubrication of the balls 3;
[0033] An oil storage tank is provided inside the outer shell 4. The inner wall of the oil storage tank is coated with an anti-oil leakage coating, which can prevent the lubricating oil from leaking and ensure that the lubricating oil can be stored in the oil storage tank for a long time. The outside of the outer shell 4 is slidably connected to the inside of the main body 1. This sliding connection method enables the outer shell 4 to move flexibly within the main body 1, adapting to the position changes of the balls 3 under different working conditions. Both the inner sides of the two outer shells 4 are rotatably connected to the rotating ring 2-5. The outer and inner sides of the rotating ring 2-5 are hardened, improving its wear resistance and corrosion resistance;
[0034] A plurality of holes are provided inside the main body 1. The design of these holes is very precise, and their sizes and positions are perfectly matched with the fixing columns 12, facilitating the installation and fixation of the sealing components and not affecting the overall structural strength of the main body 1 at the same time. The outside of the balls 3 is rotatably connected to the outside of the rotating ring 2-5. This connection method enables the balls 3 to be evenly stressed when rotating on the outside of the rotating ring 2-5, ensuring the stability of the bearing during operation. The inside of the rotating ring 2-5 is rotatably connected to the rotating shaft 6. The rotating shaft 6 adopts an advanced sealing design and is filled with high-quality grease inside, which can effectively prevent foreign impurities from entering and ensure its own good lubrication effect;
[0035] At the top of one of the outer shells 4, an oil inlet 7 is fixedly connected. The oil inlet 7 can prevent the lubricating oil from leaking out, thus affecting the lubrication effect of the oil storage tank and the balls 3. A piston 8 is slidably connected inside the oil inlet 7. The piston 8 is made of rubber sealing material and has good sealing performance, which can effectively prevent the lubricating oil from leaking from the oil inlet 7. Sealing components for sealing are slidably connected to both the upper and lower ends of the main body 1. The sealing components can effectively prevent foreign impurities such as dust and moisture from entering the inside of the main body 1, protecting the normal operation of the bearing and other components.
[0036] Refer to Figure 2 、 Figure 4 , a fixing column 12 is fixedly connected inside the sealing component. The fixing column 12 is made of high-strength stainless steel material and has strong compressive capacity, capable of withstanding various forces during the installation and use of the sealing component. A limiting component for restricting it is fixedly connected inside the fixing column 12. The limiting component can ensure the firm installation of the sealing component on the main body 1, preventing the sealing component from loosening during the operation of the robot;
[0037] The sealing assembly includes two sealing shells 9. The sealing shells 9 are made of engineering plastics. This material has good corrosion resistance and insulation, can adapt to different working environments, and has a certain elasticity, which is easy to install. The inner sides of the two sealing shells 9 are slidably connected to the outer side of the main body 1. This sliding connection makes the sealing shells 9 more convenient to install and disassemble, while ensuring the sealing effect. The inside of the sealing shell 9 is fixedly connected with a sealing ring 10. The sealing ring 10 is made of a high-temperature resistant and wear-resistant rubber material. It can maintain good sealing performance under different temperature environments and prevent impurities from entering through the gap between the sealing shell 9 and the outer shell 4;
[0038] The inside of the sealing shell 9 is fixedly connected with a sealing ring 11. The sealing ring 11 is also made of high-quality rubber material. Its special shape and material can fit tightly on the outside of the rotating shaft 6, effectively preventing impurities from entering from the gap between the rotating shaft 6 and the sealing shell 9. The bottom of the sealing ring 10 is slidably connected to the outside of the outer shell 4. This sliding connection method can ensure the seal while allowing the outer shell 4 to move within a certain range. One side of the sealing ring 11 is slidably connected to the outside of the rotating shaft 6. This connection method can be flexibly adjusted as the rotating shaft 6 rotates, always maintaining a good sealing state;
[0039] The limiting assembly includes a plurality of rotating rods 13, which are made of high-strength metal materials and have a surface anti-rust treatment to ensure stability and reliability during long-term use. Both ends of the rotating rod 13 are fixedly connected to the inside of the fixed column 12. This fixing method allows the rotating rod 13 and the fixed column 12 to form a stable integral structure. The outer side of the rotating rod 13 is rotatably connected to a limiting plate 14, which can be flexibly rotated around the rotating rod 13, which is convenient for operation when installing and disassembling the sealing assembly. The outer side of the limiting plate 14 is slidably connected to the inside of the fixed column 12, and the outer side of the limiting plate 14 is slidably connected to the inside of the main body 1. The rear side of the limiting plate 14 is fixedly connected to a spring 15, and the other end of the spring 15 is fixedly connected to the inside of the fixed column 12, and the inside of the fixed column 12 is fixedly connected to a limiting rod 16.
[0040] Working principle: When the staff needs to install the bearing, the two outer shells 4 can wrap the ball 3. The outer side of the outer shell 4 is connected with a first rotating ring 2. When the rotating shaft 6 rotates, the ball 3 can be driven through the second rotating ring 5, so that the ball 3 can be wrapped. The inner part of the top outer shell 4 is connected with an oil inlet 7. The inner parts of the two outer shells 4 are provided with oil storage grooves. When the lubricating oil is poured into the oil storage grooves from the oil inlet 7, the outlet of the oil storage groove will be blocked by one side of one of the balls 3, so that it cannot leak out. When the ball 3 rotates, the lubricating oil can be smeared on the inner side of the first rotating ring 2. When the first rotating ring 2 rotates to the outside of other balls 3, the lubricating oil can be smeared on the outside of other balls 3, so as to realize automatic lubrication of the ball 3.
[0041] After the outer shell 4 is installed, the sealing shell 9 can be installed on the outer side of the main body 1 from the upper and lower ends of the main body 1, so as to achieve the sealing effect. The inner part of the sealing shell 9 is connected with a second sealing ring 11 and a first sealing ring 10. The outer side of the first sealing ring 10 contacts the gap between the sealing shell 9 and the main body 1, and the outer side of the second sealing ring 11 contacts the gap between the sealing shell 9 and the rotating shaft 6. There are also a plurality of fixing columns 12 fixedly connected inside the sealing shell 9. The inner part of the fixing column 12 is rotatably connected with a limiting plate 14, and the limiting plate 14 will be ejected by the spring 15, so as to fix the sealing shell 9 on the outer side of the main body 1. Under normal circumstances, the limiting plate 14 will be ejected from the inner part of the fixing column 12 by the spring 15. When the sealing shell 9 is installed on the outer side of the main body 1, because there are holes in the main body 1 to facilitate the entry of the fixing column 12, when the fixing column 12 reaches a certain position, the limiting plate 14 will be ejected by the groove formed in the hole.
