With adjustments to its corporate strategy and the expansion of market demand, the company is actively leveraging its strengths to develop the industrial supporting product market, particularly in fields requiring high precision, such as the application of aluminum alloy materials in photovoltaic power generation equipment and the processing of aluminum alloy materials for the interior of rail transit vehicles. These fields place extremely high demands on the processing precision of supporting products, requiring not only excellent physical and chemical properties of the materials themselves but also precise control of the movement trajectory of each component during processing to ensure the quality and performance of the final product.

[0003] In the fields of industrial automation and precision manufacturing, ultra-precision rotary mechanisms are key equipment for achieving high-precision rotary control. These mechanisms typically need to achieve high-precision rotary motion within a limited space to meet the stringent requirements for rotational accuracy in precision machining, measurement, and inspection applications. However, to achieve this goal, it is essential to ensure that the rotating components remain on a predetermined trajectory throughout their movement, avoiding machining errors or equipment malfunctions caused by trajectory deviations.

[0004] Traditional rotary mechanism guide devices often fail to meet the requirements of high-precision rotation, especially under long-term operation or high load conditions, and are prone to wear and vibration, leading to a decrease in rotational accuracy. To solve this problem, the company has developed a base guide device based on circular motion. This device significantly improves the motion accuracy and stability of the rotary mechanism by optimizing the guide rail layout, using a ball bearing mechanism to reduce friction, and integrating lubrication and cleaning mechanisms, providing strong support for the high-precision machining of industrial products.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A base guiding device based on circular motion includes a number of guide rails arranged in a circular array. A slider is slidably connected to the outer surface of each guide rail. Ball bearing mechanisms are provided on both sides of the inner side of the slider. A lubrication mechanism is provided at the front end of the slider, and a cleaning mechanism is provided at the rear end of the slider. A base plate is movably connected to the upper surface of the slider. A first connecting hole is provided on both the base plate and the upper surface of the slider.

[0012] To facilitate the rolling of the balls, the ball mechanism of this utility model, which is a base guide device based on circular motion, includes grooves on both sides of the inner side of the slider. Balls are rolled inside the grooves, and the number of balls is several. The balls are evenly arranged inside the grooves, and isolators are rolled on the outer surface of the balls.

[0013] To facilitate lubrication, the lubrication mechanism of this utility model, which is a base guide device based on circular motion, includes an oil groove on the outer surface of the end cover, the oil groove extending to the ball bearing mechanism, an oil nozzle fixedly connected to the top of the outer surface of the end cover, and a one-way valve fixedly connected to the outer surface of the oil nozzle.

[0014] To facilitate the cleaning of the guide rail, the cleaning mechanism of this utility model, which is a base guide device based on circular motion, includes a retainer fixed on both sides of the outer surface of the second scraper. A connecting rod is engaged on the inner side of the retainer, and a sponge roller is rotatably connected to the middle of the outer surface of the connecting rod.

The slider, end caps, tail caps, and other components are connected by bolts, making installation simple and quick, and facilitating subsequent disassembly and maintenance. This device can be configured with different numbers of guide rails to increase its versatility. Whether in the processing of aluminum alloy materials in photovoltaic power generation equipment or the application of aluminum alloy materials inside rail transit vehicles, the high-precision rotation requirements in different applications can be met by adjusting the number of guide rails.

[0026] Example

[0027] like Figure 1-5 As shown, a base guiding device based on circular motion includes a guide rail 1, the number of guide rails 1 being several, and the several guide rails 1 being evenly arranged in a circular array. A slider 2 is slidably connected to the outer surface of the guide rail 1. A ball bearing mechanism 3 is provided on both sides of the inner side of the slider 2. A lubrication mechanism 4 is provided at the front end of the slider 2. A cleaning mechanism 5 is provided at the rear end of the slider 2. A base plate 6 is movably connected to the upper surface of the slider 2. A first connecting hole 7 is provided on both the base plate 6 and the upper surface of the slider 2. A first bolt 8 is threaded into the first connecting hole 7.

[0028] In practical use, the guide rail 1, slider 2, ball bearing mechanism 3, and base plate 6 are arranged to form a circular guide rail by combining multiple arc-shaped guide rails 1. Different numbers of guide rails 1 can be selected for combination according to requirements, increasing the applicability of the device. It can provide a continuous and closed motion trajectory, ensuring that the slider 2 always moves along the predetermined circular path, avoiding motion errors caused by discontinuous trajectory, and achieving high-precision circumferential guidance. This ensures that the slider 2 maintains a stable trajectory during movement, avoiding deviation caused by vibration or external force. The inner side of the slider 2 contacts the guide rail 1 through the ball bearing mechanism 3, which can significantly reduce friction and wear during movement, improve the accuracy and flexibility of movement, and improve the reliability of the device. The lubrication mechanism 4 reduces friction and impact between moving parts, and the cleaning mechanism 5 can effectively wipe away dust, impurities, and lubricant residues on the surface of the guide rail 1, keeping the guide rail 1 clean. The base plate 6 is placed on the upper surface of the slider 2, and the first bolt 8 is threaded into the corresponding first connecting hole 7, thereby fixing the base plate 6 and providing a stable mounting platform for the ultra-tight rotating mechanism, ensuring that the rotating mechanism will not vibrate or deviate during movement due to unstable installation.

[0029] In this embodiment, the upper surface of the guide rail 1 is provided with a mounting hole 9, which penetrates the guide rail 1, and a sealing plug 10 is movably connected to the top of the inner side of the mounting hole 9.

[0030] In practical use, the mounting hole 9 and the sealing plug 10 are designed so that the guide rail 1 can be fixed by external screws. After fixing, the sealing plug 10 blocks the opening on the surface of the mounting hole 9, effectively preventing dust, impurities, liquids and other contaminants from entering the interior of the guide rail 1, keeping the interior of the guide rail 1 clean and extending its service life.

[0031] In this embodiment, an end cap 11 is movably connected to one side of the outer surface of the slider 2, and a tail cap 12 is movably connected to the other side of the outer surface of the slider 2.

[0032] In practical use, the end cap 11 and the tail cap 12 can seal the front and rear ends of the slider 2, preventing dust, impurities, liquids and other contaminants from entering the interior of the slider 2, protecting the internal ball bearing mechanism 3 from contamination, thereby extending its service life. At the same time, they can enhance the overall rigidity of the slider 2, reduce deformation and vibration during movement, and improve the structural stability of the slider 2.

[0033] In this embodiment, a first scraper 13 is movably connected to the outer surface of the end cap 11, and a second scraper 14 is movably connected to the outer surface of the tail cap 12.

[0034] In practical use, the first scraper 13 and the second scraper 14 are set to make close contact with the guide rail 1, scraping off excess lubricant and retaining it inside the slider 2, ensuring that the lubricant is always in the part that needs lubrication, maintaining a good lubrication effect, reducing lubricant waste, and lowering the cost of lubricant use. At the same time, it can prevent external dust, impurities and contaminants from entering the interior of the slider 2, avoiding the possibility that impurities may cause jamming or accelerated wear of moving parts.

[0035] In this embodiment, the first scraper 13, the second scraper 14, the end cap 11, the tail cap 12 and the slider 2 are provided with second connecting holes 15 on both sides of their outer surfaces, and the second connecting holes 15 are threaded with second bolts 16.

[0036] In practical use, the second bolt 16 is threaded into the corresponding second connecting hole 15, so that the first scraper 13, the second scraper 14, the end cover 11 and the tail cover 12 are connected to the slider 2. The installation process is simpler and faster, and it can be quickly disassembled, making it convenient for maintenance personnel to operate.

[0037] In this embodiment, the ball mechanism 3 includes grooves 301 formed on both sides of the inner side of the slider 2. Balls 302 are rolled inside the grooves 301. There are several balls 302, which are evenly arranged inside the grooves 301. Isolators 303 are rolled on the outer surface of the balls 302.

[0038] In practical use, through the setting of the ball mechanism 3, the groove 301 is opened on the inner side of the slider 2, which facilitates the placement of the ball 302. Multiple balls 302 are connected by multiple isolators 303, so that the balls 302 are evenly distributed on the path of the groove 301 under the guidance of the isolators 303, avoiding collision and wear between the balls 302 and extending the service life of the balls 302.

[0039] In this embodiment, the lubrication mechanism 4 includes an oil groove 401 formed on the outer surface of the end cap 11, the oil groove 401 extending through to the ball bearing mechanism 3, an oil nozzle 402 fixedly connected to the top of the outer surface of the end cap 11, and a one-way valve 403 fixedly connected to the outer surface of the oil nozzle 402.

[0040] In practical use, through the setting of the lubrication mechanism 4, the oil nozzle 402 is fixed on the outer surface of the end cover 11 near the port of the oil groove 401. The two work together to accurately deliver the lubricant into the interior of the groove 301, ensuring that the lubricant can evenly cover the surface of the ball 302, avoiding insufficient or excessive lubrication, reducing friction and impact between moving parts, thereby reducing the noise level of the device and improving the comfort of the working environment. The one-way valve 403 only allows the lubricant to flow in one direction to prevent the lubricant from flowing back.

[0041] In this embodiment, the cleaning mechanism 5 includes a retainer 501 fixed on both sides of the outer surface of the second scraper 14. A connecting rod 502 is engaged on the inner side of the retainer 501, and a sponge roller 503 is rotatably connected to the middle of the outer surface of the connecting rod 502.

[0042] In practical use, the connecting rod 502 is engaged inside the card holder 501 through the setting of the cleaning mechanism 5, which makes it easy to install and disassemble the sponge roller 503 and to clean and replace it after long-term use, so as to ensure the cleaning effect. The sponge roller 503 rotates on the surface of the guide rail 1, which can effectively wipe away the dust, impurities and lubricant residues on the surface of the guide rail 1, keep the guide rail 1 clean, and ensure that the entire surface of the guide rail 1 is always in good condition.

[0043] Working principle: In use, the slider 2 is connected to one of the guide rails 1, and then multiple guide rails 1 are combined into a circular guide rail, providing a continuous and closed motion trajectory. This ensures that the slider 2 always moves along the predetermined circular path, avoiding motion errors caused by discontinuous trajectories and achieving high-precision circumferential guidance. The inner side of the slider 2 contacts the guide rail 1 through the ball mechanism 3, which can significantly reduce friction and wear during the movement process, improving the accuracy and flexibility of the movement. The lubrication mechanism 4 ensures that the lubricant can be evenly covered on the surface of the ball 302, reducing friction and impact between moving parts. The cleaning mechanism 5 can effectively wipe away dust, impurities, and lubricant residues on the surface of the guide rail 1, keeping the guide rail 1 clean. The base plate 6 provides a stable mounting platform for the ultra-tight rotating mechanism, ensuring that the rotating mechanism will not vibrate or deviate during the movement due to unstable installation. The end cap 11 and the tail cap 12 seal the front and rear ends of the slider 2, protecting the internal ball mechanism 3 from contamination. The first scraper 13 and the second scraper 14 scrape off excess lubricant and retain it inside the slider 2, ensuring that the lubricant is always in the parts that need lubrication and maintaining a good lubrication effect.
