Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool slider technology, specifically a high-efficiency CNC machine tool slider with a self-lubricating structure. Background Technology

[0002] In the field of CNC machine tools, the slider is a key component for linear motion, and its performance directly affects the machining accuracy and efficiency of the machine tool.

[0003] Traditional CNC machine tool slides experience significant friction between the slide and the guide rail during operation. This not only accelerates slide wear and reduces its lifespan but also generates excessive heat, affecting the machine tool's machining accuracy. Furthermore, the lack of an effective self-lubricating structure necessitates regular manual lubrication, increasing maintenance costs and workload. Uneven or delayed lubrication can also negatively impact slide operation. Existing slide lubrication structures are often complex, unreliable, and prone to failure, resulting in poor lubrication. Additionally, some lubrication systems are inconvenient to operate when adding lubricant or performing maintenance, requiring the disassembly of numerous components, increasing maintenance difficulty and time costs. Therefore, we propose a high-efficiency CNC machine tool slide with a self-lubricating structure. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency CNC machine tool slider with a self-lubricating structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency CNC machine tool slider with a self-lubricating structure includes a slider body, which is mounted on a slide rail. A roller is rotatably mounted inside the slider body, contacting the slide rail. A first gear is connected to the rotating shaft of the roller via a key. An oil reservoir is located at the top of the slider body, with an opening at its bottom. A second gear is also rotatably mounted inside the slider body, with a through hole that mates with the opening. A collecting cylinder is located at the bottom of the slider body, with a support rod slidably mounted on it. A piston is located at the top end of the support rod inside the collecting cylinder. A liquid outlet pipe is located on the side wall of the collecting cylinder. A sponge is located inside the slider body below the liquid outlet end of the pipe, and the sponge contacts the roller.

[0007] As a further embodiment of this utility model: a water tank is also provided inside the slider body, the support rod passes through the side wall of the water tank and extends into the water tank, and a float is provided on the support rod inside the water tank.

[0008] As a further improvement of this utility model, a maintenance plate is provided on the side wall of the slider body by means of fixing bolts.

[0009] As a further improvement of this utility model, an oil injection pipe is provided on the oil tank.

[0010] As a further improvement of this utility model, the water tank is also provided with a water injection pipe and a drain pipe.

[0011] As a further improvement of this utility model, sealing plugs are provided on the oil injection pipe, water injection pipe and drain pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The rollers inside the slider contact the slide rail to ensure sliding efficiency. At the same time, the oil tank, the second gear, the collection cylinder and other components work together. When the through hole is aligned with the bottom opening of the oil tank, the lubricating oil flows into the collection cylinder. As the lubricating oil in the collection cylinder increases, it pushes the support rod and the piston to move. When the piston is below the inlet end of the outlet pipe, the lubricating oil is discharged through the outlet pipe, collected by the sponge and evenly applied to the rollers, realizing self-lubrication of the rollers, reducing friction between the slider and the slide rail, reducing wear, and improving the service life and running accuracy of the slider.

[0014] 2. The slide block sidewall is equipped with an inspection plate for easy inspection of internal components; the oil tank is equipped with an oil filling pipe for easy addition of lubricating oil; the water tank is equipped with a water filling pipe and a drain pipe for easy replenishment or replacement of water; the oil filling pipe, water filling pipe and drain pipe are all equipped with sealing plugs to ensure sealing, making the maintenance and operation of the slide block more convenient, reducing maintenance costs and workload, and improving the efficiency of the machine tool.

Furthermore, in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of the utility model. Any obvious modifications or alterations made to this utility model do not depart from its spirit and scope.

[0020] Example

[0021] Please see Figures 1-3 In this embodiment of the utility model, a high-efficiency CNC machine tool slider with a self-lubricating structure includes a slider body 1, which is mounted on a slide rail 2. A maintenance plate 3 is mounted on the side wall of the slider body 1 by fixing bolts 301. Under the action of the maintenance plate 3, it is convenient to carry out maintenance work on the internal components of the slider body 1, thereby ensuring the efficiency of the slider body 1.

[0022] Inside the slider body 1, a roller 5 is rotatably mounted. The roller 5 contacts the slide rail 2. Under the action of the roller 5 and the slide rail 2, the sliding efficiency of the slider body 1 is ensured. A first gear 6 is connected to the rotating shaft of the roller 5 via a key. An oil tank 8 is also mounted on the upper part of the slider body 1. The bottom of the oil tank 8 has an opening. A second gear 7 is also rotatably mounted inside the slider body 1. The second gear 7 has a through hole that cooperates with the opening. A collecting cylinder 9 is also mounted on the lower part of the slider body 1. A support rod 11 is slidably mounted on the collecting cylinder 9. A piston 10 is mounted at the top end of the support rod 11 inside the collecting cylinder 9. When the through hole is aligned with the opening, the lubricating oil stored in the oil tank 8 will enter the collecting cylinder 9 through the opening and the through hole, which facilitates the subsequent lubrication of the roller 5. An oil injection pipe 4 is mounted on the oil tank 8. Under the action of the oil injection pipe 4, it is convenient to add lubricating oil into the oil tank 8.

[0023] The slider body 1 is also equipped with a water tank 13. The support rod 11 passes through the side wall of the water tank 13 and extends into the water tank 13. A float ball 12 is installed on the support rod 11 inside the water tank 13. An outlet pipe 17 is also installed on the side wall of the collection cylinder 9. When the lubricating oil stored in the collection cylinder 9 reaches a certain amount, the piston 10 will push the float ball 12 downward through the support rod 11, thereby causing the piston 10 to move downward. When the piston 10 is below the inlet end of the outlet pipe 17, the lubricating oil inside the collection cylinder 9 will be discharged through the outlet pipe 17. A sponge 16 is installed inside the slider body 1 below the outlet end of the outlet pipe 17. The sponge 16 is in contact with the roller 5. At this time, the lubricating oil discharged through the outlet pipe 17 will be collected by the sponge 16. Under the action of the sponge 16, the lubricating oil will be evenly spread on the roller 5, thereby realizing the lubrication of the roller 5, and thus enabling the slider body 1 to have a uniform self-lubricating function.

[0024] The water tank 13 is also equipped with a water injection pipe 14 and a drain pipe 15. The water injection pipe 14 and the drain pipe 15 facilitate the replenishment or replacement of water inside the water tank 13, thereby ensuring the efficiency of the float 12. The oil injection pipe 4, the water injection pipe 14 and the drain pipe 15 are all equipped with sealing plugs to ensure their sealing performance and thus their efficiency.

[0025] In actual use, the slider body 1 is fitted with a maintenance plate 3 via fixing bolts 301 for easy maintenance of internal components. The slider body 1 slides on the slide rail 2, and the internal rotating roller 5 contacts the slide rail 2 to ensure sliding efficiency. The first gear 6, keyed to the rotating shaft of the roller 5, is associated with the subsequent lubrication structure. The oil tank 8 stores lubricating oil, which can be added through the oil filling pipe 4. The bottom opening of the oil tank 8 engages with the through hole on the second gear 7. When the through hole aligns with the opening, the lubricating oil flows into the collection cylinder 9. A support rod 11 is slidably installed inside the collection cylinder 9, and a piston 10 is located at the top of the support rod 11. At the same time, the support rod 11 passes through the water tank 13, and a float ball 12 is installed in the part of the support rod 11 inside the water tank 13. As the lubricating oil in the collection cylinder 9 increases, the piston 10 pushes the float ball 12 downward through the support rod 11. When the piston 10 is below the inlet end of the outlet pipe 17, the lubricating oil is discharged through the outlet pipe 17. Inside the slider body 1, below the liquid outlet end of the liquid outlet pipe 17, the sponge 16 contacts the roller 5. The discharged lubricating oil is collected by the sponge 16 and evenly applied to the roller 5, achieving a self-lubricating function. The water tank 13 is replenished or replaced with water through the water inlet pipe 14 and the drain pipe 15 to ensure the normal use of the float 12. The sealing plugs on the oil inlet pipe 4, the water inlet pipe 14, and the drain pipe 15 ensure the sealing of each component, ensuring the efficient and stable operation of the entire self-lubricating structure and improving the efficiency and lifespan of the slider body 1.
