Description

Technical Field

[0001] This application relates to the technical field of linear guides, and particularly to a self-lubricating linear guide slider. Background Art

[0002] As a key mechanical component used to precisely guide and support an object to perform linear reciprocating motion, a linear guide mainly consists of a guide rail and a slider. The guide rail, as a fixed track, is usually a long strip-shaped component with a high-precision plane or groove, installed on a fixed structure such as the base or bracket of the equipment, providing a crucial reference straight line for the entire motion system. The slider is a component closely connected to the moving part and can slide extremely smoothly on the guide rail. Generally, the slider contains rolling elements such as ball bearings or roller bearings. These rolling elements continuously roll between the slider and the guide rail, greatly reducing the friction force, enabling the slider to perform linear motion along the guide rail with high precision, high speed, and low resistance. Linear guides are widely used in various equipment fields that require precise linear motion, such as machine tools, automated production lines, robots, and precision measuring instruments, and can effectively improve the motion accuracy, stability, and service life of the equipment;

[0003] Currently, in the prior art, by optimizing the mechanism of the linear guide, lubricating structures for lubricating the slider body and the slide rail are respectively arranged at both ends of the slider body. When the slider body slides on the linear guide, the cleaning component can clean the slide rail, effectively removing dust and impurities on the slide rail. Subsequently, the coating component coats the lubricating oil in the oil storage component onto the slide rail, thereby realizing the lubrication function. This optimization improves the original structure without increasing the number of slider parts and the combined length of the slider, greatly saving the production cost and also improving the convenience of space use. However, during its use, only an oil storage block can be used for oil storage, and the oil storage capacity is relatively limited. Moreover, it is still necessary for personnel to frequently replenish the lubricating oil regularly, which only prolongs the consumption time of the lubricating oil. At the same time, during the use process, the lubricating oil cannot be quickly and evenly lubricated onto the guide rail slider. Thus, it can be seen that this structure has certain defects, so there is an urgent need to improve it. Summary of the Utility Model

[0004] The embodiment of this application provides a self-lubricating linear guide slider to solve the problem that the current self-lubricating linear guide slider cannot automatically and quickly apply lubricating oil and has a poor self-lubricating function.

[0005] The embodiment of the present application provides a self-lubricating linear guide slider, comprising: a bottom plate, a guide rail body is fixedly installed on the top of the bottom plate, a slider body is slidably connected to the outside of the guide rail body, a self-lubricating mechanism is fixedly installed on the top of the slider body, a linkage mechanism is fixedly installed on the back of the slider body, and a mounting plate is fixedly installed on the top front side of the slider body;

[0006] The self-lubricating mechanism includes an oil tank and an oil guide roller. The oil tank is fixedly installed on the top of the slider body, the oil guide roller is rotatably connected to the top of the slider body, the bottom of the oil guide roller is fit-connected to the top of the guide rail body, and an oil discharge assembly is fixedly installed on the bottom of the oil tank, and the bottom of the oil discharge assembly passes through the slider.

[0007] In a feasible implementation, mounting holes are provided at four corners of the bottom of the mounting plate, and the mounting holes are configured as countersunk holes.

[0008] In a feasible implementation, the oil discharge assembly includes an oil guide hopper, a transverse tube is fixedly installed at the bottom of the oil guide hopper, the bottom output end of the transverse tube passes through the slider body and is arranged above the oil guide roller, the interior of the transverse tube is rotatably connected to a rotating shaft, and the outer surface of the rotating shaft is fixedly installed with oil guide plates at equal intervals.

[0009] In a feasible implementation, the linkage mechanism includes an elastic member and a gear, the elastic member is arranged at the lower end of the back side of the slider body, the rear end of the rotating shaft passes through the transverse tube, the top of the transverse tube is connected to the bottom of the oil tank, the gear is fixedly installed at the rear end of the rotating shaft, and the gear and the elastic member are meshingly connected.

[0010] In a feasible implementation, the elastic member includes a mounting groove and a linkage rod, the mounting groove is opened at the lower end of the back side of the slider body, a torsion spring is fixedly installed on the inner side of the mounting groove, a turntable is fixedly installed on the rear end of the torsion spring, a gear ring is fixedly installed on the outer side of the turntable, the gear ring is connected to the gear transmission, a toggle rod is fixedly connected to the back side of the turntable, the linkage rod is fixedly installed on the top rear side of the base plate at equal intervals, and the side shape of the toggle rod is L-shaped.

[0011] In a feasible implementation, a sealing cover is threadedly connected to the top of the oil tank, and an observation window is provided on the front of the oil tank.

[0012] In a feasible implementation, the inner side of the slider body is in a convex shape, and the cross-sectional shape of the guide rail body is in an I-shape.

[0013] The embodiment of the present application provides a self-lubricating linear guide slider. During use, the device can assist in installing the required device through the mounting plate and the mounting holes thereon. By adjusting the slider body to slide on the guide rail body, the device or equipment installed on the mounting plate can be flexibly driven to move. In this process, the sliding of the slider body plays an important role. When the slider body slides, the oil guide roller can be driven to rotate. At this time, the lubricating oil flowing out of the self-lubricating mechanism can be evenly applied to the top of the guide rail body. As the slider body continues to slide, the lubricating oil can be gradually applied to the outer surface of the guide rail body, thereby playing a lubricating role.

[0014] During the sliding of the slider body, the slider body will also drive the toggle rod to contact the linkage rod. When the toggle rod contacts the linkage rod, the linkage rod will swing. As the toggle rod swings, the turntable will be started to drive the gear to rotate. At this time, the torsion spring is compressed, and the rotation of the gear ring can drive the gear to rotate. The rotation of the gear can drive the shaft to rotate. After the shaft rotates, the oil guide plate located inside the transverse tube can be driven to rotate. The rotation of the oil guide plate can drive the lubricating oil inside the transverse tube to flow, and the lubricating oil flows to the oil guide roller. The oil guide roller rotates in contact with the guide rail body, and the lubricating oil can be automatically introduced into the outer surface of the guide rail body, thereby playing a better lubricating role.

[0015] When the toggle rod passes over the linkage rod, the torsion spring resets and drives the turntable drive shaft to reset, which can further drive the oil guide plate to rotate. This design enables the device as a whole to have a good oil guide automatic lubrication function during use. Moreover, the oil tank equipped with the device has a large capacity and can store more lubricating oil. This feature makes it unnecessary to frequently add lubricating oil during use of the device, which greatly improves the overall ease of use of the device and provides reliable lubrication guarantee for various equipment requiring precise linear motion.

[0028] In order to enable those skilled in the art to better understand the technical solutions in this application, the following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0029] Example

[0030] refer to Figures 1 to 4 A self-lubricating linear guide slider of this embodiment includes: a base plate 100, a guide rail body 200 is fixedly installed on the top of the base plate 100, a slider body 300 is slidably connected to the outer side of the guide rail body 200, a self-lubricating mechanism 500 is fixedly installed on the top of the slider body 300, a linkage mechanism 600 is fixedly installed on the back of the slider body 300, and a mounting plate 400 is fixedly installed on the top front side of the slider body 300;

[0031] The self-lubricating mechanism 500 includes an oil tank 510 and an oil guiding roller 520. The oil tank 510 is fixedly installed on the top of the slider body 300. The oil guiding roller 520 is rotatably connected to the inner top of the slider body 300. The bottom of the oil guiding roller 520 is in close connection with the top of the guide rail body 200. A drain component 530 is fixedly installed at the bottom of the oil tank 510. The bottom of the drain component 530 penetrates through the slider. The guide rail body 200 fixedly installed on the top of the bottom plate 100 and the slider body 300 slidingly connected on the outside form a basic linear motion structure. In the self-lubricating mechanism 500 on the top of the slider body 300, the oil tank 510 is fixedly installed on the top of the slider body 300, providing sufficient lubricating oil reserve for the entire lubrication system. The oil guiding roller 520 is rotatably connected to the inner top of the slider body 300, and its bottom is in close connection with the top of the guide rail body 200. This design enables the oil guiding roller 520 to rotate as the slider moves during the sliding process of the slider body 300.

[0032] When the lubricating oil in the oil tank 510 is discharged through the drain component 530 at the bottom, the oil guiding roller 520 can evenly apply the lubricating oil to the top of the guide rail body 200. As the slider body 300 continues to slide, the lubricating oil can gradually cover the entire outer surface of the guide rail body 200, achieving effective lubrication of the guide rail. This self-lubricating structure eliminates the need for additional manual lubrication operations, reducing maintenance costs and workload. At the same time, since the oil tank 510 is directly installed on the top of the slider body 300, it can promptly supply lubricating oil to the oil guiding roller 520, ensuring the continuity and stability of lubrication. The mounting plate 400 installed on the front side of the top of the slider body 300 facilitates the connection of other devices or equipment, enabling this linear guide rail slider to be conveniently integrated into the system in various application scenarios. This self-lubricating linear guide rail slider realizes an efficient and stable self-lubricating function through its unique structural design.

[0033] Mounting holes 700 are provided at the four bottom corners of the mounting plate 400, and the mounting holes 700 are set as countersunk holes. A sealing cover 540 is threadedly connected to the top of the oil tank 510. An observation window 550 is provided on the front of the oil tank 510. The inner shape of the slider body 300 is convex, and the cross-sectional shape of the guide rail body 200 is I-shaped. The mounting holes 700 provided at the four bottom corners of the mounting plate 400 are designed as countersunk holes. This design enables the heads of the connecting components to sink into the mounting plate 400 when connecting other devices or equipment, ensuring the flatness of the mounting surface and also improving the stability and firmness of the connection.

[0034] The threaded connection sealing cover 540 on the top of the oil tank 510 ensures the sealing performance of the oil tank 510, preventing the leakage of lubricating oil and the entry of external impurities into the oil tank 510, guaranteeing the cleanliness and quality of the lubricating oil, and thus enabling a continuous and stable lubricating effect to be provided for the guide rail. An observation window 550 is provided on the front of the oil tank 510, facilitating the user to observe the remaining amount of lubricating oil in the oil tank 510 at any time, so as to replenish the lubricating oil in a timely manner and ensure the normal operation of the lubrication system. The inner shape of the slider body 300 is convex, matching the guide rail body 200 with an I-shaped cross-section. This design makes the sliding of the slider body 300 on the guide rail body 200 more stable, effectively preventing the slider body 300 from shifting or detaching from the guide rail during movement, and improving the accuracy and reliability of linear motion.

[0035] The oil drainage assembly 530 includes an oil guide hopper 531. A transverse pipe 532 is fixedly installed at the bottom of the oil guide hopper 531. The bottom output end of the transverse pipe 532 penetrates through the slider body 300 and is arranged above the oil guide roller 520. A rotating shaft 533 is rotatably connected inside the transverse pipe 532. Oil guide plates 534 are fixedly installed at equal intervals on the outer surface of the rotating shaft 533. The oil guide hopper 531 in the oil drainage assembly 530 can effectively collect the lubricating oil flowing out of the oil tank 510 and guide it into the transverse pipe 532. The bottom output end of the transverse pipe 532 penetrates through the slider body 300 and is arranged above the oil guide roller 520, ensuring that the lubricating oil can accurately flow to the oil guide roller 520. The rotating shaft 533 rotatably connected inside the transverse pipe 532 and the oil guide plates 534 fixedly installed at equal intervals on the outer surface of the rotating shaft 533 play an important role. When the slider body 300 slides, it can drive the rotating shaft 533 to rotate through a specific linkage mechanism, and then the oil guide plates 534 rotate inside the transverse pipe 532. The rotation of the oil guide plates 534 can promote the flow of the lubricating oil inside the transverse pipe 532, making it flow more smoothly towards the oil guide roller 520, avoiding blockage and poor flow during the oil drainage process. This design can ensure that the lubricating oil is supplied to the oil guide roller 520 at a relatively stable flow rate, thus guaranteeing the continuous lubrication of the guide rail body 200. At the same time, the equal interval distribution of the oil guide plates 534 also helps to evenly distribute the lubricating oil and improve the consistency of the lubricating effect. The oil drainage assembly 530 plays a key role in the discharge and transportation of the lubricating oil through its reasonable structural design, providing strong support for the self-lubricating function of the linear guide rail slider.

[0036] The linkage mechanism 600 includes an elastic member 610 and a gear 620. The elastic member 610 is arranged at the lower end of the back side of the slider body 300. The rear end of the rotating shaft 533 passes through the transverse tube 532. The top of the transverse tube 532 is connected to the bottom of the oil tank 510. The gear 620 is fixedly installed at the rear end of the rotating shaft 533. The gear 620 and the elastic member 610 are meshed and connected. The elastic member 610 includes a mounting groove 611 and a linkage rod 630. The mounting groove 611 is opened at the lower end of the back side of the slider body 300. A torsion spring 612 is fixedly installed inside the mounting groove 611. A rotating disk 613 is fixedly installed at the rear end of the torsion spring 612. A toothed ring 614 is fixedly installed outside the rotating disk 613. The toothed ring 614 and the gear 620 are transmission-connected. A toggle rod 615 is fixedly connected to the back side of the rotating disk 613. The linkage rod 630 is fixedly installed at the top rear side of the bottom plate 100 at equal intervals. The side shape of the toggle rod 615 is set in an L shape. The elastic member 610 in the linkage mechanism 600 is arranged at the lower end of the back side of the slider body 300, playing a key connection and transmission role. The rear end of the rotating shaft 533 passes through the transverse tube 532, and the top of the transverse tube 532 is connected to the bottom of the oil tank 510, ensuring a smooth flow path of the lubricating oil.

[0037] The gear 620 is fixedly installed at the rear end of the rotating shaft 533 and is connected to the gear ring 614 in the elastic member 610 by transmission, so as to realize the transmission of power. The installation groove 611 of the elastic member 610 is opened at the lower end of the back of the slider body 300, providing installation space for components such as the torsion spring 612 and the rotating disk 613. The torsion spring 612 in the installation groove 611 can store and release energy during the operation of the device. The gear ring 614 is fixedly installed on the outer side of the rotating disk 613 at the rear end of the torsion spring 612. The transmission connection between the gear ring 614 and the gear 620 ensures that the rotation of the rotating shaft 533 can be accurately controlled. The side shape of the toggle rod 615 on the back of the rotating disk 613 is set in an L-shaped manner. During the sliding process of the slider body 300, when the toggle rod 615 contacts the linkage rod 630 fixedly installed at equal intervals on the rear side of the top of the bottom plate 100, a series of mechanical actions will be triggered.

[0038] As the slider body 300 moves, the toggle rod 615 interacts with the linkage rod 630 to rotate the turntable 613, and then drives the gear 620 to rotate through the gear ring 614, thereby driving the rotating shaft 533 and the oil guide plate 534 in the transverse tube 532 to rotate, thereby promoting the flow of lubricating oil. This design enables the sliding of the slider body 300 to be linked with the supply of lubricating oil, ensuring that lubricating oil can be provided to the guide rail body 200 in a timely and accurate manner during the movement of the slider. At the same time, the presence of the torsion spring 612 enables the toggle rod 615 to quickly reset after passing over the linkage rod 630, preparing for the next lubrication action. In summary, the linkage mechanism 600, through its complex and sophisticated structural design, realizes the organic combination of slider movement and lubrication function, and improves the self-lubricating performance and operating stability of the linear guide slider.

[0039] The principle and advantages of use are as follows: during actual use, the device can effectively assist in the installation of various devices required to be undertaken through the mounting plate 400 and the mounting holes 700 carefully arranged thereon. When operating, by adjusting the slider body 300 to slide smoothly on the guide rail body 200, the device or equipment installed on the mounting plate 400 can be driven to move very flexibly. In this process, the sliding of the slider body 300 plays a vital role. When the slider body 300 starts to slide, it can drive the oil guide roller 520 to rotate accordingly. At this time, the lubricating oil flowing out of the self-lubricating mechanism 500 will be applied to the top of the guide rail body 200 in a uniform state. As the slider body 300 continues to slide, the lubricating oil can be gradually and comprehensively applied to the outer surface of the guide rail body 200. In this way, it can provide effective lubrication for the guide rail body 200, ensuring the smoothness and stability of the entire device during operation.

[0040] During the sliding process of the slider body 300, the slider body 300 will also drive the toggle rod 615 to contact the linkage rod 630. When the toggle rod 615 and the linkage rod 630 collide with each other, the linkage rod 630 will quickly make a swinging reaction. As the toggle rod 615 continues to swing, the turntable 613 will be activated to drive the gear 620 to rotate. At this time, the torsion spring 612 will be compressed, and the rotation of the gear ring 614 can drive the gear 620 to rotate, and the rotation of the gear 620 can drive the rotating shaft 533 to rotate. When the rotating shaft 533 rotates, the oil guide plate 534 located inside the transverse tube 532 can be driven to rotate. Through the rotation of the oil guide plate 534, the lubricating oil inside the transverse tube 532 can be effectively driven to flow, and the lubricating oil is forced to flow toward the direction of the oil guide roller 520. When the oil guide roller 520 rotates in contact with the guide rail body 200, the lubricating oil can be automatically introduced into the outer surface of the guide rail body 200, thereby playing a better lubricating role.

[0041] When the toggle rod 615 passes over the linkage rod 630, the torsion spring 612 will quickly reset, thereby driving the turntable 613 to drive the rotating shaft 533 to perform a reset operation. In this way, the oil guide plate 534 can be further driven to rotate. This ingenious design allows the entire device to have an extremely excellent oil guide automatic lubrication function during use. Moreover, the oil tank 510 equipped with the device has a large capacity and can store a large amount of lubricating oil. This significant feature eliminates the need for frequent addition of lubricating oil during use of the device, greatly improving the overall ease of use of the device and providing reliable, stable and efficient lubrication guarantees for various equipment that require precise linear motion, so that these devices can always maintain good performance during operation.
