Description

Technical Field

[0001] This invention relates to the field of linear guide rail technology, and more specifically to a highly reliable linear guide rail with a lubrication oil circuit structure. Background Technology

[0002] Linear guides, also known as linear guides or linear rails, are mechanical components used to support and guide moving parts, enabling them to reciprocate linearly in a given direction. A linear guide typically consists of a rail, a slider, and rolling elements (balls or rollers). The rail surface is machined with precision raceways, and the slider contains rolling elements. The linear movement of the slider along the rail is achieved by the rolling of these rolling elements within the rail raceways. Linear guides are a type of rolling guide; the steel balls continuously circulate between the slider and the rail, allowing the load platform to perform high-precision linear motion along the rail. They have a low coefficient of friction, reducing it to one-fiftieth of that of traditional sliding guides, and can withstand loads in all directions, providing smooth movement and low noise.

[0003] During normal operation of linear guideways, dust or debris from the environment inevitably accumulates on the guideway surface. These particles are easily carried into the space between the steel balls and the raceway during the reciprocating motion of the slider, mixing with the lubricating oil on the steel ball surface to form sludge containing impurities. As operating time increases, this mixture accumulates, gradually affecting the smoothness of the steel ball rolling. In severe cases, it can even cause the steel balls to get stuck in the circulation channel. At the same time, the mixed hard debris will scratch or accelerate wear on the surface of the steel balls, increasing the surface roughness of the steel balls and thus increasing the frictional resistance between the steel balls and the guideway raceway. This results in a significant increase in overall running resistance, manifested as a noticeable feeling of blockage and lack of smoothness during movement.

[0004] Therefore, how to design a highly reliable linear guide rail with a lubrication circuit structure is a technical problem that engineers need to solve. Summary of the Invention

[0005] The purpose of this invention is to provide a highly reliable linear slide rail with a lubrication circuit structure to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A high-reliability linear slide rail with a lubrication circuit structure specifically includes: a slide rail, on which a slider is slidably connected; a base frame is fixedly installed at the bottom of the slider, the base frame being made of engineering plastic, preferably PPS or PEEK, for supporting and protecting the slider; several steel balls are rotatably connected in a rounded rectangular shape inside the slider, with the steel balls and slider being in a compression fit; several external wall scraping mechanisms are installed inside the slider, arranged linearly, for cleaning the surface deposits of the steel balls, ensuring the surface of the steel balls remains clean as they circulate within the device, thus enabling stable operation of the device; an external wall oiling mechanism is provided on one side of the external wall scraping mechanism, linearly installed inside the slider, for applying oil to the surface of the cleaned steel balls, lubricating the surface, improving the smoothness of the steel ball's movement, and protecting the surface of the steel balls, thus enabling better operation of the device.

[0007] Furthermore, the outer wall scraping mechanism includes a fixed ring fixedly installed inside the slider. Elastic connecting arms are fixedly installed at equal intervals on one side of the fixed ring. Each end of the elastic connecting arm is equipped with a cleaning base block, and several cleaning base blocks are arranged in a ring. The cleaning base blocks and the surface of the steel ball are pressed against each other to clean the adhering substances on the surface of the steel ball. The outer wall scraping mechanism also includes a flow groove opened inside the cleaning base block. Each end of the cleaning base block is fixedly installed with a connecting pipe, and the end of the connecting pipe away from the cleaning base block is equipped with a connecting ring. One end of the connecting ring is fixedly installed with a discharge pipe. The bottom end of the base frame is provided with a discharge port, and the discharge port is fixedly connected to the end of the discharge pipe.

[0008] During operation, the steel balls inside the device remain in contact with the surface of the slide rail. As the slider moves back and forth along the slide rail, the steel balls in contact with the slide rail enter the internal cavity of the slider synchronously with the movement of the slider. After entering the slider, the steel balls will pass through multiple linearly arranged outer wall scraping mechanisms in sequence according to a preset trajectory. Through the step-like scraping action of each outer wall scraping mechanism, the impurities attached to the surface of the steel balls are gradually removed, ensuring that the surface of the steel balls remains clean. This, in turn, ensures the fitting accuracy and smooth movement between the steel balls, the slide rail, and the slider.

[0009] The steel ball enters the cleaning area formed by several cleaning blocks. As the steel ball continues to move towards the cleaning blocks, it exerts a squeezing force on the blocks. This squeezing force is transmitted to the elastic connecting arm connected to the blocks, causing the arm to undergo adaptive elastic deformation to match the steel ball's trajectory. When the steel ball continues to move and comes into contact with the cleaning end of the block, the cleaning end, being arc-shaped and conforming to the outer surface contour of the steel ball, achieves full contact with the surface of the steel ball. This allows the cleaning end to scrape away the mixture of dust, lubricating oil, and debris remaining on the surface of the steel ball.

[0010] The mixture generated by the scraping and cleaning process is guided by the movement of steel balls and enters the flow channel corresponding to the cleaning block. As the device continues to operate, the mixture gradually accumulates in the flow channel and flows along the guide direction of the flow channel. It then enters the connecting pipe and connecting ring connected to the flow channel in sequence, and is finally discharged outside the device through the discharge pipe and discharge port connected to the connecting ring. This completes the centralized collection and discharge of impurities, preventing impurities from accumulating inside the device and affecting the stability of the device's operation.

[0011] Furthermore, the cleaning base block has a guide groove at the end facing the steel ball. The guide groove is inclined at 40°. Several cleaning base blocks are arranged to form a central area. The guide groove is used to guide the steel ball into the central area.

[0012] To improve the smoothness of the steel ball entering the cleaning blocks, a guide groove is provided at the end of the cleaning blocks. The guide groove can effectively restrict and guide the movement trajectory of the steel ball. The guide groove is set at a 40° angle, which helps to improve the smoothness of the steel ball during movement, so that it can enter the central area formed by the cleaning blocks more smoothly. After entering the central area, the surface of the steel ball can be cleaned by the cleaning end of the cleaning blocks.

[0013] Furthermore, the side of the flow channel near the cleaning end of the cleaning base block is set with an inclined structure to guide the cleaned impurities so that they can be discharged smoothly along the flow channel; the position of the flow channel near the cleaning end of the cleaning base block is provided with an anti-backflow block to prevent the discharged impurities from flowing back into the cleaning area.

[0014] The end of the flow channel is provided with a sloped structure, which can guide the mixture generated during cleaning to smoothly enter the flow channel. At the same time, the sloped structure increases the effective inlet area of ​​the mixture entering the flow channel, thereby improving the smoothness of the mixture entering the device. In order to prevent the mixture from flowing back during the discharge process, the flow channel is provided with an anti-backflow block near the sloped structure. This anti-backflow block can effectively prevent the mixture from flowing back, further improving the stability and reliability of the mixture discharge.

[0015] Furthermore, a support arm is fixedly provided on the side of the fixing ring away from the elastic connecting arm. The support arm matches the cleaning base block, and the end of the support arm can apply a compressive force to the cleaning base block to support it.

[0016] To improve the smoothness and stability of the cleaning block when scraping steel balls, a support arm is installed behind the cleaning block in the direction of force. This arm provides effective support for the cleaning block, limits excessive displacement of the cleaning block during operation, and prevents a decrease in the overall stability of the device due to excessive movement of the cleaning block.

[0017] Furthermore, the outer wall oiling mechanism includes an installation cylinder equidistantly fixedly installed inside the slider. A top column is fixedly installed at the top of the installation cylinder, and a rubber column is installed inside the top column. An extrusion column is slidably connected inside the bottom of the installation cylinder. An installation ring is sleeved on the top of the extrusion column. Elastic strips are fixedly installed at equal intervals on the outer ring of the installation ring, and the ends of the elastic strips are fixedly connected to the inner wall of the installation cylinder. An installation frame is fixedly installed inside the installation cylinder, and a limit post is fixedly installed at the bottom of the installation frame. The limit post and the extrusion column are in a compression fit.

[0018] After the steel balls have run normally and completed cleaning, they will enter the lower part of the mounting cylinder. As the steel balls move to the lower position of the mounting cylinder, they will push the extrusion column upward. As the extrusion column is pushed upward, the lubricating oil inside the mounting cylinder will flow along the guide groove to the surface of the steel balls. The lubricating oil forms a coating layer on the surface of the steel balls, thereby lubricating them and ensuring that the steel balls remain smooth during subsequent operation. When the steel balls are removed from under the extrusion column, the extrusion column will reset under the elastic restoring force of the elastic strip, thereby preventing the continuous outflow of lubricating oil and preventing excessive accumulation of lubricating oil in the movement channel of the steel balls. In addition, in order to prevent the extrusion column from moving too high, a limit post is set above the extrusion column to limit the upward stroke of the extrusion column, further improving the stability and smoothness of the device operation.

[0019] Furthermore, the bottom end of the mounting cylinder is provided with a mating groove that is pressed and engaged with the end of the extrusion column, and the bottom end of the extrusion column is semi-circular.

[0020] The mating groove at the bottom of the mounting cylinder facilitates the passage of steel balls and creates a tighter compression fit between the end of the extrusion column and the steel balls. This allows the extrusion column to contact and act more stably on the steel balls when pushed by them, thereby further improving the fitting accuracy and operational reliability of the various components of the device.

[0021] Furthermore, the bottom end of the mounting cylinder is provided with a mounting groove, and a bonding sponge is fixedly installed in the mounting groove at the bottom end of the mounting cylinder.

[0022] The sponge installed at the bottom of the mounting cylinder can further clean the surface of the steel ball as it passes through, and can also absorb excess lubricating oil. Since the outer wall oiling mechanism is set in a linear arrangement, multiple oiling may lead to excessive lubricating oil on the surface of the steel ball. The sponge can effectively absorb excess lubricating oil and prevent lubricating oil from accumulating on the surface of the steel ball. At the same time, the sponge can re-coat the absorbed lubricating oil evenly on the surface of the steel ball, thereby further improving the lubrication uniformity of the steel ball surface and making the lubrication effect more stable and reliable.

[0023] Furthermore, both ends of the base frame are provided with placement grooves, and irregularly shaped sponges are fixedly installed in the placement grooves at both ends of the base frame, with the end face of the irregularly shaped sponge fitting against the surface of the slide rail.

[0024] The base frame has irregularly shaped sponges installed in the slots at both ends. These sponges can clean the surface of the slide rails during the operation of the device. The sponges are filled with lubricating oil, which lubricates the slide rails while cleaning them. Through the synergistic effect of cleaning and lubrication, the friction between the slide rails and related components can be effectively reduced, further improving the smoothness and stability of the overall operation of the device.

[0025] Furthermore, both ends of the base frame are provided with sliding grooves that slide with the slide rail. The sidewalls of the sliding grooves at both ends of the base frame are symmetrically provided with protrusions that slide with the slide rail. The protrusions at the bottom of the base frame can quickly clean impurities attached to the surface of the slide rail, preventing impurities from entering the slider and causing jamming. By timely removing impurities from the surface of the slide rail, the smooth sliding of the slider on the slide rail can be effectively guaranteed, further improving the overall smoothness and stability of the device's operation.

[0026] The technical solution provided by this invention may include the following beneficial effects: 1. In this example, the outer wall scraping mechanism arranged linearly inside the slider achieves stepped cleaning of the steel ball surface. The cleaning base blocks are distributed in a ring and precisely fit the steel ball surface. With the help of the 40° inclined guide groove, the steel ball can be guided smoothly into the cleaning area, effectively scraping off the mixture of dust, debris and lubricating oil. The scraped impurities are discharged in a centralized manner through the conveying channel formed by the flow channel and connecting pipe. The anti-backflow block in the channel prevents impurities from flowing back, and the lubricating oil in the mixture can reduce the friction of the channel and form a sealing barrier to prevent external impurities from seeping in. This prevents blockage inside the device from the source and ensures the matching accuracy and smooth movement of the steel ball, slide rail and slider.

[0027] 2. In this example, the cleaned steel balls are lubricated by the outer wall oiling mechanism. When the steel balls move, they lift the extrusion column, causing the lubricating oil in the mounting cylinder to flow along the guide groove to the surface of the steel balls to form a protective film. After the steel balls are removed, the elastic strip drives the extrusion column to reset, preventing excessive accumulation of lubricating oil. The limiting column ensures the stable movement of the extrusion column. The sponge at the bottom of the mounting cylinder can absorb excess lubricating oil and re-coat it evenly. At the same time, the irregularly shaped sponges at both ends of the base frame can clean and lubricate the surface of the slide rail. The synergistic effect of the multiple lubrication structures significantly reduces the frictional resistance between the steel balls and the slide rail, improves the smoothness of the device operation, and protects the steel balls and the slide rail.

[0028] 3. In this example, the protrusions on the side wall of the base slide can clean impurities on the slide rail surface in advance. Combined with the cleaning and lubrication function of the shaped sponge, a double protection is formed, reducing the probability of impurities entering the slide block. By timely removing impurities from the slide rail surface, the smooth sliding of the slide block on the slide rail can be effectively guaranteed, further improving the overall smoothness and stability of the device's operation. Through the overall structure's collaborative design of "cleaning-lubrication-protection", component wear is reduced, the risk of jamming is lowered, the service life of the device is extended, and the high reliability of operation is greatly improved.

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] The technical solution of the present invention (Embodiment 1) is described in detail below with reference to the accompanying drawings.

[0037] See Figure 1 , Figure 2 and Figure 3 This highly reliable linear slide rail with a lubrication circuit structure specifically includes: a slide rail 1, a slider 2 slidably connected to the slide rail 1, a base frame 3 fixedly installed at the bottom of the slider 2, the base frame 3 being made of engineering plastic, using PPS or PEEK material, used to support and protect the slider 2, a number of steel balls 4 rotatably connected in a rounded rectangle inside the slider 2, and the steel balls 4 and the slider 2 are squeezed together, a number of outer wall scraping mechanisms 5 are installed inside the slider 2, and the outer wall scraping mechanisms 5 are arranged linearly, used to clean the surface of the steel balls 4, so that the steel balls 4 circulate in the device and maintain the surface cleanliness, thereby enabling the device to operate stably; an outer wall oiling mechanism 6 is provided on one side of the outer wall scraping mechanism 5, and the outer wall oiling mechanism 6 is linearly installed inside the slider 2, used to apply oil to the surface of the cleaned steel balls 4, lubricate the surface of the steel balls 4, improve the smoothness of the operation of the steel balls 4, and protect the surface of the steel balls 4, so that the device can operate better; Example

[0038] Since dust or debris adhering to the surface of the slide rail 1 will adhere to the surface of the steel ball 4, as the slide rail 1 and the slider 2 continue to operate, the dust or debris adhering to the surface of the steel ball 4 will be carried into the interior of the slider 2 and adhere to the inner wall of the slider 2. Over time, the interior of the slider 2 will become blocked, which will cause the device to fail to operate normally, thus requiring the device to be disassembled and repaired. Therefore, this device is equipped with an outer wall scraping mechanism 5 for cleaning the surface of the steel ball 4, which can continuously clean the surface of the steel ball 4 during operation, prevent the accumulation of dust or debris, and enable the device to operate continuously.

[0039] See Figure 4 , Figure 5 and Figure 6 The outer wall scraping mechanism 5 includes a fixed ring 7 fixedly installed inside the slider 2. Elastic connecting arms 8 are fixedly installed at equal intervals on one side of the fixed ring 7. Cleaning base blocks 9 are installed at the ends of the elastic connecting arms 8, and several cleaning base blocks 9 are arranged in a ring. The cleaning base blocks 9 and the surface of the steel ball 4 are pressed together to clean the adhering substances on the surface of the steel ball 4. The outer wall scraping mechanism 5 also includes a flow groove 11 opened inside the cleaning base block 9. Connecting pipes 12 are fixedly installed at the ends of the cleaning base blocks 9, and connecting rings 13 are installed at the ends of the connecting pipes 12 away from the cleaning base blocks 9. A discharge pipe 14 is fixedly installed at one end of the connecting ring 13. A discharge port 15 is opened at the bottom of the base frame 3, and the discharge port 15 is fixedly connected to the end of the discharge pipe 14.

[0040] During operation, the steel ball 4 inside the device remains in contact with the surface of the slide rail 1. When the slider 2 moves back and forth along the slide rail 1, the steel ball 4, which is in contact with the slide rail 1, enters the internal cavity of the slider 2 synchronously with the movement of the slider 2. After entering the interior of the slider 2, the steel ball 4 will pass through multiple linearly arranged outer wall scraping mechanisms 5 in sequence according to a preset trajectory. Through the step-like scraping action of each outer wall scraping mechanism 5, the impurities attached to the surface of the steel ball 4 are gradually removed, ensuring that the surface of the steel ball 4 remains clean, thereby ensuring the matching accuracy and smooth movement between the steel ball 4, the slide rail 1, and the slider 2.

[0041] The steel ball 4 enters the cleaning area formed by several cleaning blocks 9. As the steel ball 4 continues to move towards the cleaning blocks 9, it exerts a squeezing force on the cleaning blocks 9. This squeezing force is transmitted to the elastic connecting arm 8 connected to the cleaning blocks 9, causing the elastic connecting arm 8 to undergo adaptive elastic deformation to match the entry trajectory of the steel ball 4. When the steel ball 4 continues to move and comes into contact with the cleaning end of the cleaning block 9, the cleaning end of the cleaning block 9 has an arc-shaped structure that matches the outer surface contour of the steel ball 4, enabling it to fully adhere to the surface of the steel ball 4. Thus, through the scraping action of the cleaning end, the mixture of dust, lubricating oil, and debris remaining on the surface of the steel ball 4 is scraped away.

[0042] The mixture generated by the scraping and cleaning process is guided by the movement of the steel ball 4 and enters the flow channel 11 corresponding to the cleaning base block 9. As the device continues to operate, the mixture gradually accumulates in the flow channel 11 and flows along the guide direction of the flow channel 11. It then enters the connecting pipe 12 and the connecting ring 13 connected to the flow channel 11 in sequence, and is finally discharged outside the device through the discharge pipe 14 and the discharge port 15 connected to the connecting ring 13. This completes the centralized collection and discharge of impurities, preventing impurities from accumulating inside the device and affecting the stability of the device's operation.

[0043] It should be noted that the mixture generated during scraping and cleaning will accumulate inside the conveying channel, which is composed of the flow channel 11, connecting pipe 12, connecting ring 13, and discharge pipe 14. Since the mixture contains lubricating oil, it can effectively reduce the frictional resistance between the mixture and the inner wall of the channel, allowing the mixture to flow smoothly in the conveying channel and avoiding blockage. As the end of the flow channel 11 continues to feed into the channel, the mixture in the channel will gradually accumulate and be subjected to continuous squeezing force. Under the push of this squeezing force, the mixture will smoothly pass through the discharge pipe 14 and be smoothly discharged from the outside of the device through the discharge port 15. At the same time, the mixture accumulated in the channel can form a natural sealing barrier, which can effectively prevent other impurities from seeping back into the device through the conveying channel, and can maintain the moisture inside the channel, preventing the mixture from drying out and causing blockage of the channel, preventing impurities from interfering with the normal operation of the internal components of the device, thereby ensuring the smoothness and stability of the device's long-term operation.

[0044] In addition, the linearly arranged outer wall scraping mechanism 5 can perform stepped cleaning on the surface of the steel ball 4. The installation angles of each outer wall scraping mechanism 5 can be matched with each other, so that the gap between adjacent cleaning base blocks 9 can be adapted to the surface by the deviation of the installation angle of the outer wall scraping mechanism 5, thereby improving the adhesion effect on the surface of the steel ball 4 and achieving more comprehensive and effective cleaning.

[0045] See Figure 4 , Figure 5 and Figure 6 The cleaning base block 9 has a guide groove 10 at the end facing the steel ball 4. The guide groove 10 is inclined at 40°. Several cleaning base blocks 9 are enclosed to form a central area. The guide groove 10 is used to guide the steel ball 4 into the central area.

[0046] To improve the smoothness of the steel ball 4 entering the cleaning base block 9, a guide groove 10 is provided at the end of the cleaning base block 9. The guide groove 10 can effectively restrict and guide the movement trajectory of the steel ball 4. The guide groove 10 is set at an angle of 40°, which helps to improve the smoothness of the steel ball 4 during movement, so that it can enter the central area enclosed by the cleaning base block 9 more smoothly. After entering the central area, the surface of the steel ball 4 can be cleaned by the cleaning end of the cleaning base block 9.

[0047] See Figure 4 , Figure 5 and Figure 6 The side of the flow channel 11 near the cleaning end of the cleaning base block 9 is set with a sloping structure to guide the cleaned impurities so that the impurities can be discharged smoothly along the flow channel 11; the flow channel 11 near the cleaning end of the cleaning base block 9 is provided with an anti-backflow block to prevent the discharged impurities from flowing back into the cleaning area.

[0048] The end of the flow channel 11 is provided with a sloped structure, which can guide the mixture generated during cleaning to smoothly enter the interior of the flow channel 11. At the same time, the sloped structure increases the effective inlet area of ​​the mixture entering the flow channel 11, thereby improving the smoothness of the mixture entering the device. In order to prevent the mixture from flowing back during the discharge process, the flow channel 11 is provided with an anti-backflow block near the sloped structure. The anti-backflow block can effectively prevent the mixture from flowing back, further improving the stability and reliability of the mixture discharge.

[0049] See Figure 4 , Figure 5 and Figure 6 The fixing ring 7 has a support arm 16 fixedly installed on the side away from the elastic connecting arm 8. The support arm 16 matches the cleaning base block 9. The end of the support arm 16 can apply a compressive force to the cleaning base block 9 to support it.

[0050] In order to improve the smoothness and stability of the cleaning block 9 when scraping the steel ball 4, a support arm 16 is provided behind the cleaning block 9 in the direction of force. This arm can provide effective support for the cleaning block 9, limit the excessive displacement of the cleaning block 9 during operation, and thus avoid the overall stability of the device from decreasing due to excessive movement of the cleaning block 9. Example

[0051] After cleaning the steel ball 4, the surface of the steel ball 4 lacks lubrication, which increases the friction between the steel ball 4 and the slide rail 1 during operation. This is not conducive to the stable operation of the device. Therefore, the device is equipped with an outer wall oiling mechanism 6 for lubricating the surface of the steel ball 4, so that the surface of the steel ball 4 is evenly coated with lubricating oil, which allows the device to operate smoothly.

[0052] See Figure 7 The outer wall oiling mechanism 6 includes an installation cylinder 17 that is fixedly installed at equal intervals inside the slider 2. A top column 18 is fixedly installed at the top of the installation cylinder 17. A rubber column 19 is installed inside the top column 18. An extrusion column 21 is slidably connected inside the bottom end of the installation cylinder 17. An installation ring 22 is sleeved on the top of the extrusion column 21. An elastic strip 23 is fixedly installed at equal intervals on the outer ring of the installation ring 22. The end of the elastic strip 23 is fixedly connected to the inner wall of the installation cylinder 17. An installation frame 25 is fixedly installed inside the installation cylinder 17. A limit column 26 is fixedly installed at the bottom end of the installation frame 25. The limit column 26 and the extrusion column 21 are in a compression fit.

[0053] After the steel ball 4 operates normally and completes cleaning, it will enter the lower part of the mounting cylinder 17. As the steel ball 4 moves to the lower position of the mounting cylinder 17, it will push the extrusion column 21 upward. As the extrusion column 21 is pushed upward, the lubricating oil inside the mounting cylinder 17 will flow along the guide groove 24 to the surface of the steel ball 4. The lubricating oil forms a coating layer on the surface of the steel ball 4, thereby lubricating the steel ball 4 and ensuring that the steel ball 4 remains smooth during subsequent operation. When the steel ball 4 moves away from under the extrusion column 21, the extrusion column 21 is reset under the elastic restoring force of the elastic strip 23, thereby preventing the continuous outflow of lubricating oil and preventing excessive accumulation of lubricating oil in the movement channel of the steel ball 4. In addition, in order to prevent the extrusion column 21 from moving too high, a limit post 26 is set above the extrusion column 21 to limit the upward stroke of the extrusion column 21, further improving the stability and smoothness of the device operation.

[0054] See Figure 7 The bottom end of the mounting cylinder 17 is provided with a mating groove 20 that is pressed and engaged with the end of the extrusion column 21, and the bottom end of the extrusion column 21 is semi-circular.

[0055] The mating groove 20 provided at the bottom of the mounting cylinder 17 facilitates the passage of the steel ball 4, while also creating a tighter compression fit between the end of the extrusion column 21 and the steel ball 4. This allows the extrusion column 21 to contact and act more stably on the steel ball 4 when pushed by it, thereby further improving the fitting accuracy and operational reliability of the various components of the device.

[0056] See Figure 7 The bottom end of the mounting cylinder 17 is provided with a mounting groove, and a bonding sponge 27 is fixedly installed in the mounting groove at the bottom end of the mounting cylinder 17.

[0057] The adhesive sponge 27 at the bottom of the mounting cylinder 17 can further clean the surface of the steel ball 4 as it passes through, and can also absorb excess lubricating oil. Since the outer wall oiling mechanism 6 is arranged in multiple linear configurations, multiple oiling may result in excessive lubricating oil on the surface of the steel ball 4. The adhesive sponge 27 can effectively absorb excess lubricating oil and prevent it from accumulating on the surface of the steel ball 4. At the same time, the adhesive sponge 27 can re-coat the absorbed lubricating oil evenly on the surface of the steel ball 4, thereby further improving the lubrication uniformity of the steel ball 4 surface and making the lubrication effect more stable and reliable.

[0058] See Figure 8 Both ends of the base frame 3 are provided with placement slots, and irregular sponges 28 are fixedly installed in the placement slots at both ends of the base frame 3, and the end face of the irregular sponge 28 is in contact with the surface of the slide rail 1.

[0059] Shaped sponges 28 are installed in the placement slots at both ends of the base frame 3. These shaped sponges 28 can clean the surface of the slide rail 1 during the operation of the device. The interior of the shaped sponges 28 is filled with lubricating oil, so that the slide rail 1 can be lubricated while cleaning the surface of the slide rail 1. Through the synergistic effect of cleaning and lubrication, the friction between the slide rail 1 and related components can be effectively reduced, further improving the smoothness and stability of the overall operation of the device.

[0060] See Figure 8 Both ends of the base frame 3 are provided with sliding grooves that slide with the slide rail 1. The side walls of the sliding grooves at both ends of the base frame 3 are symmetrically provided with protrusions that slide with the slide rail 1. The protrusions at the bottom of the base frame 3 can quickly clean the impurities attached to the surface of the slide rail 1, preventing impurities from entering the slider 2 and causing jamming. By timely removing impurities from the surface of the slide rail 1, the smooth sliding of the slider 2 on the slide rail 1 can be effectively guaranteed, further improving the overall smoothness and stability of the device operation.
