The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides a machine tool guide rail structure that can reduce wear, such as Figure 1-4 As shown, the machine tool guide rail structure that can reduce wear includes: a base plate 1; two support seats 2, both of which are fixedly installed on the base plate 1; two sliders 3, both of which are slidably arranged on the two support seats 2; a fixed plate 4, both of which are fixedly installed on the two sliders 3; a ball 5, a plurality of ball 5, and the plurality of ball 5 are respectively rollingly installed in the two sliders 3; two arc grooves 6, both of which are respectively opened on the two support seats 2; a liquid storage tank 7, which is fixedly installed on the bottom of the fixed plate 4 and is arranged between the two support seats 2; a transmission mechanism, which is arranged in the liquid storage tank 7 for transmitting lubricating oil to the ball 5.

[0022] In this embodiment, the base plate 1 serves as the basic support of the entire mechanism to ensure the stability and reliability of the mechanism. The support seat 2 provides a stable sliding track for the slider 3. The slider 3 slides on the support seat, carrying the fixed plate 4 and the workpiece thereon to move. The design of the slider 3 allows it to move smoothly on the support seat 2, and it is the core component of the guide rail mechanism. The fixed plate 4 is used to install workpieces or processing tools to ensure stability and precision during processing. Multiple balls 5 are respectively rolled and installed in the two sliders 3, which greatly reduces friction, reduces wear, and improves the service life of the guide rail. The arc groove 6 cooperates with the ball 5 in the slider 3 to ensure that the ball 5 rolls smoothly in the arc groove 6, further reducing friction. The liquid storage tank 7 is used to store lubricating oil, and the lubricating oil is transmitted to the ball 5 through the transmission mechanism, which plays a role in lubrication and cooling, and prolongs the service life of the guide rail. The transmission mechanism is arranged in the liquid storage tank, which is responsible for transmitting the lubricating oil from the liquid storage tank 7 to the ball. This design ensures that the ball 5 is always well lubricated during long-term work, further improving the reliability and service life of the guide rail. The overall design structure is simple and easy to install and maintain, which reduces the workload of staff and improves work efficiency.

[0023] In a further preferred embodiment of the utility model, the transmission mechanism includes a water pump 8, a liquid inlet pipe 9, a liquid discharge pipe 10, a three-way pipe 11 and two connecting pipes 12, the water pump 8 is fixedly mounted on the liquid storage tank 7, the liquid inlet pipe 9 is fixedly mounted on the input end of the water pump 8, the liquid discharge pipe 10 is fixedly mounted on the output end of the water pump 8, the three-way pipe 11 is fixedly mounted on the liquid discharge pipe 10, the two connecting pipes 12 are both fixedly mounted on the three-way pipe 11, the two connecting pipes 12 pass through the liquid storage tank 7 and extend into the slider 3, and the two connecting pipes 12 are respectively arranged corresponding to the plurality of balls 5.

[0024] In this embodiment, the water pump 8 is fixedly mounted on the liquid storage tank 7 as the power source of the transmission mechanism. The water pump 8 can extract the lubricating oil in the liquid storage tank 7 and transport it to the part that needs lubrication through the drain pipe 10. The inlet pipe 9 is responsible for introducing the lubricating oil in the liquid storage tank 7 into the water pump 8. The design of the inlet pipe 9 ensures the stable supply of lubricating oil and provides a reliable source of fluid for the entire transmission mechanism. The drain pipe 10 is responsible for transporting the lubricating oil pressurized by the water pump 8 to the part that needs lubrication. The design of the drain pipe 10 ensures the fluidity and transmission efficiency of the lubricating oil. The three-way pipe 11 plays a role of diversion, and can transfer the lubricating oil from the drain pipe 10 to the two connecting pipes 12 respectively, ensuring that the balls 5 in the two sliders 3 can be fully lubricated. The design of the connecting pipe 12 ensures that the lubricating oil can be directly transferred to the balls 5 in the slider 3, thereby achieving accurate lubrication of the balls 5. In addition, the two connecting pipes 12 are respectively arranged corresponding to the multiple balls 5, ensuring that each ball 5 can be fully lubricated. The fluidity and transmission efficiency of the lubricating oil are ensured by the pressurizing action of the water pump 8, thereby improving the lubrication effect. The overall design takes into account the stable supply and precise transmission of the lubricating oil, ensuring the efficient and stable operation of the sliding guide mechanism.

[0025] In a further preferred embodiment of the utility model, a driving mechanism is provided on the base plate 1 for driving the slider 3 and the fixed plate 4 to move, and the driving mechanism includes two fixed blocks 13, a driving block 14, a screw 15 and a driving motor 16, the two fixed blocks 13 are fixedly mounted on the base plate 1, the driving block 14 is fixedly mounted on the bottom of the liquid storage tank 7, the driving block 14 is arranged between the two fixed blocks 13, the screw 15 is rotatably mounted on the two fixed blocks 13, the screw 15 is threadedly connected to the driving block 14, the driving motor 16 is fixedly mounted on the base plate 1, and the output shaft of the driving motor 16 is fixedly connected to the screw 15.

[0026] In this embodiment, the two fixing blocks 13 provide a stable installation foundation for the screw 15. The driving block 14 is provided with a thread matching the screw 15, so that the screw 15 can drive the driving block 14 to perform linear motion when rotating. When the screw 15 rotates, the driving block 14 will perform linear motion along the axial direction of the screw 15. By controlling the rotation of the driving motor 16, the rotation control of the screw 15 can be achieved, and then the linear motion of the driving block 14 can be controlled. Through the coordinated use of the driving motor 16 and the screw 15, the automatic control of the slider 3 and the fixed plate 4 is achieved. This greatly improves the working efficiency of the machine tool and reduces the need for manual operation. The driving motor 16 can accurately control the speed and direction of its output shaft, thereby achieving accurate control of the slider 3 and the fixed plate 4. This helps to improve the machining accuracy and stability of the machine tool. Due to the realization of automatic control, the operator can achieve control of the slider 3 and the fixed plate 4 by simply controlling the driving motor 16, which greatly simplifies the operation process. Automatic control reduces the influence of human factors on the operation of the machine tool and improves the reliability and stability of the machine tool.

[0027] In a further preferred embodiment of the utility model, a guide mechanism is provided on the slider 3 for assisting the slider 3 to slide along the extension direction of the support seat 2. There are multiple guide mechanisms, and the guide mechanisms include a central axis 17, a roller 18 and a movable groove 19. The central axis 17 is fixedly mounted on the slider 3, and the roller 18 is rotatably mounted on the central axis 17. The roller 18 is arranged corresponding to the support seat 2, and the movable groove 19 is opened on the support seat 2, and the movable groove 19 is in sliding contact with the roller 18.

[0028] In this embodiment, the central axis 17 is fixedly mounted on the slider 3 as a mounting base for the roller 18. The design of the roller 18 is intended to reduce the friction between the slider 3 and the support seat 2 so that the slider 3 can slide more smoothly. The movable groove 19 is provided on the support seat 2 and is in sliding contact with the roller 18. The movable groove 19 provides a limited sliding track for the roller 18, ensuring the stability and precision of the slider 3 during the sliding process. A rolling contact is formed between the roller 18 and the movable groove 19 of the support seat 2, which greatly reduces the friction compared to the traditional sliding contact, making the slider 3 smoother during the sliding process. Due to the reduction of friction, the use of the guide mechanism can reduce the wear of the slider 3 and the support seat 2, thereby extending their service life. The guide mechanism ensures the stability and precision of the slider 3 during the sliding process, thereby improving the machining accuracy of the machine tool.

[0029] In a further preferred embodiment of the utility model, two support plates 20 are fixedly installed on both sides of the two support seats 2, and the four support plates 20 are respectively arranged under the multiple central shafts 17. The bottoms of the multiple central shafts 17 are each provided with an installation groove 21, and the multiple installation grooves 21 are each rotatably installed with a balance wheel 22, and the multiple balance wheels 22 are respectively in sliding contact with the four support plates 20.

[0030] In this embodiment, two support plates 20 are fixedly installed on both sides of the two support seats 2, and these support plates are arranged below the multiple center shafts 17. The main function of the support plate 20 is to provide a stable platform to support and assist the sliding of the balance wheel 22. Mounting grooves 21 are provided at the bottom of the multiple center shafts 17, and these mounting grooves are used to install the balance wheel 22. The balance wheel 22 is in sliding contact with the support plate 20 below, and their main function is to provide additional stability and balance when the slider 3 moves. By adding the balance wheel 22, the slider 3 obtains additional support points during the movement, which greatly enhances the stability of the entire mechanism. Especially when moving at high speed or bearing a large load, the balance wheel can effectively reduce vibration and offset. The design of the balance wheel 22 also helps to distribute the load on the slider 3 more evenly, thereby reducing wear or deformation caused by excessive pressure at a single point. Due to the increased stability and uniformity of load distribution, the machining accuracy of the machine tool is also improved accordingly. By reducing unnecessary friction and wear, the design of the balance wheel 22 and the support plate 20 also helps to extend the service life of the entire sliding guide mechanism.

[0031] In a further preferred embodiment of the present invention, guide grooves are formed on the four support plates 20 , and the four guide grooves are respectively in conflict with the plurality of balance wheels 22 .

[0032] In this embodiment, guide grooves are provided on the four support plates 20. These guide grooves are designed to precisely match the balance wheels 22 to provide a more stable and accurate sliding path. The multiple balance wheels 22 are not only rotatably mounted in the mounting groove 21 of the central shaft 17, but also conflict with the guide grooves on the support plates 20. This conflicting relationship ensures that the balance wheel 22 always moves along the path of the guide groove during the sliding process, thereby achieving stable support and guidance for the slider 3. The conflicting relationship between the guide groove and the balance wheel 22 ensures the stability of the slider 3 during the sliding process. This design reduces the vibration and deviation of the slider 3 when it moves at high speed or bears a large load, thereby improving the stability of the entire mechanism.

[0033] In a further preferred embodiment of the present invention, the plurality of rollers 18 are all configured to be hourglass-shaped, and the movable grooves 19 are configured to correspond to the rollers 18 .

[0034] In this embodiment, the roller 18 is designed to be an hourglass type, also known as a dumbbell type or a double convex type, which has two convex sides and a narrower middle part. This design allows the roller 18 to better fit the contour of the movable groove 19 when rolling, reducing friction and vibration. The movable groove 19 is precisely opened on the support seat 2 to match the shape and size of the roller 18. This corresponding setting ensures that the roller 18 can roll smoothly in the movable groove 19 and reduces unnecessary gaps and shaking. The corresponding setting of the hourglass roller 18 and the movable groove 19 reduces the contact area between them, thereby reducing friction resistance. This makes the sliding of the slider 3 on the support seat 2 smoother and reduces the possibility of jamming and stagnation. Due to the reduced friction between the roller 18 and the movable groove 19 and the close fit between them, the noise and vibration generated by the mechanism during operation will also be reduced accordingly. This improves the working environment of the machine tool and the comfort of the operator.

[0035] In summary, compared with the related art, the wear-reducing machine tool guide rail structure provided by the utility model significantly improves the working efficiency and stability of the machine tool through a series of innovative designs. Specifically, the device ensures the continuous lubrication of the ball between the slider and the support seat by introducing an automatic lubrication system, reduces friction and wear, and thus extends the service life of the guide rail. At the same time, through the design of the driving mechanism, the automatic control of the slider and the fixed plate is realized, the working efficiency of the machine tool is improved, and the need for manual operation is reduced. In addition, the introduction of the guide mechanism and the balance wheel further enhances the stability of the entire mechanism and the uniformity of load distribution, and improves the machining accuracy of the machine tool. The utility model achieves the purpose of improving the working efficiency, stability and machining accuracy of the machine tool as a whole.
