Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, and more specifically, to a machine tool linear slide rail with a lubrication structure. Background Technology

[0002] In the machine tool industry, the application of linear guideways has greatly simplified the design, manufacturing, and assembly of machine tool guideways. Traditional machine tool guideway designs are complex and manufacturing processes are cumbersome, while the use of linear guideways not only simplifies these processes but also significantly improves the rigidity and load-bearing capacity of the machine tool. This not only improves the performance of the machine tool but also reduces production costs and assembly difficulty.

[0003] However, existing linear guides on the market inevitably experience oxidation and rust during long-term use. These problems increase the frictional resistance of the guides, affecting their normal operation. To maintain the lubrication performance of the guides, manual application of lubricating oil is usually required. This method is not only time-consuming and labor-intensive, but uneven application can also lead to a decrease in the sliding accuracy of the guides. Furthermore, due to the lack of self-cleaning function, the surface of linear guides easily accumulates dust, chips, and other impurities. These impurities not only affect the lubrication effect of the guides but also accelerate wear, further reducing their service life and working accuracy. Especially in high-precision machining applications, the presence of these impurities can directly affect the quality of machined parts, causing unnecessary economic losses. Currently, no effective solutions have been proposed to address the problems in this technology. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a machine tool linear guide with a lubrication structure to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A machine tool linear guide with a lubrication structure includes a guide body, a slider movably sleeved on the top of the guide body, a lubrication mechanism inside the slider, and cleaning mechanisms on both sides of the slider.

[0007] Furthermore, in order to lubricate the slide rail during the movement of the slider, the lubrication mechanism includes grooves on both sides of the slider, an oil storage box inside the groove, a connecting pipe at the bottom of the oil storage box, a filter screen at the connection between the connecting pipe and the oil storage box, the connecting pipe matching the through groove, a ball bearing at one end of the through groove, and a fixing mechanism on both sides of the oil storage box.

[0008] Furthermore, to facilitate the disassembly and cleaning of the oil storage box, the fixing mechanism includes fixing blocks located on both sides of the oil storage box. The bottom of the fixing block is provided with a sliding groove, and there are two locking blocks inside the sliding groove. The two locking blocks are connected by a telescopic spring. The slider is provided with a locking groove that matches the fixing block.

[0009] Furthermore, a limit block is connected above the card block, and a limit groove is provided above the slide, with the limit groove matching the limit block.

[0010] Furthermore, the cleaning mechanism includes fixed plates on both sides of the slider, with threaded holes on the fixed plates. A threaded rod is threadedly connected inside the threaded holes, with one end of the threaded rod rotatably connected to the scraper and the other end of the threaded rod having a rotating plate.

[0011] Furthermore, the threaded rod is provided with limiting rods on both the upper and lower sides. The limiting rods are fixedly connected to the scraper, and one end of the limiting rod is connected through the fixed plate.

[0012] Furthermore, a sealing cap is detachably connected to the top of the oil reservoir.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) By setting up a lubrication mechanism and a fixing mechanism, the ball bearings can contact the slide rail, lubricating the contact surface during the movement of the slider, ensuring the sliding accuracy of the slide rail. The design of the lubrication mechanism allows the lubricating oil to be evenly distributed on the contact surface of the slide rail and the slider, thereby reducing friction and wear, and ensuring the sliding accuracy and service life of the slide rail. Furthermore, by setting a filter screen inside the oil reservoir, particulate matter and other impurities in the lubricating oil can be effectively intercepted, ensuring the purity of the lubricating oil. The filter screen design can effectively capture and intercept tiny particles and impurities in the lubricating oil, preventing them from entering the contact surface of the slide rail and the slider, thereby reducing equipment wear caused by impurities, improving the reliability and service life of the equipment, and by setting up a fixing mechanism, it is convenient to disassemble the oil reservoir and clean the impurities on the filter screen and the oil reservoir.

[0015] (2) By incorporating a cleaning mechanism, when it is necessary to clean the dust adhering to the slide rail, the scraper on one side of the slider can be moved to contact the slide rail, allowing the scraper to move along the direction of the slide rail, thereby effectively scraping away the dust and impurities adhering to the slide rail surface. This design not only ensures the lubrication effect of the slide rail but also reduces slide rail wear and malfunctions caused by dust and impurities, improving the service life and working accuracy of the slide rail. In addition, the cleaning mechanism is simple and convenient to operate, allowing users to perform cleaning operations at any time as needed, thus maintaining the cleanliness and lubrication effect of the slide rail.

[0027] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0028] In practical applications, during the movement of slider 2, the ball bearing 306 contacts the slide rail body 1, lubricating the contact surface and ensuring the sliding accuracy of the slide rail body 1. When it is necessary to clean the dust attached to the slide rail body 1, the scraper 404 on one side of the slider 2's movement direction can be moved. By rotating the threaded rod 403, the scraper 404 is driven closer to the slide rail body 1, making the scraper 404 contact the slide rail body 1. During the movement of slider 2, the scraper 404 can scrape off the dust and impurities attached to the slide rail surface. When it is necessary to clean and maintain the oil storage box 302, the limit block 6 can be moved to drive the locking block 503 into the slide groove 502, thereby enabling the oil storage box 302 to be disassembled for easy cleaning of impurities on the storage box and filter screen 304.

[0029] In summary, by utilizing the above-mentioned technical solution of this utility model, and by setting up the lubrication mechanism 3 and the fixing mechanism 5, the ball bearings 306 can contact the slide rail. During the movement of the slider 2, the contact surface can be lubricated, ensuring the sliding accuracy of the slide rail. The design of the lubrication mechanism 3 allows the lubricating oil to be evenly distributed on the contact surface between the slide rail and the slider 2, thereby reducing friction and wear, and ensuring the sliding accuracy and service life of the slide rail. Furthermore, by setting a filter screen 304 inside the oil storage box 302, particulate matter and other impurities in the lubricating oil can be effectively intercepted, ensuring the purity of the lubricating oil. The design of the filter screen 304 can effectively capture and intercept tiny particles and impurities in the lubricating oil, preventing them from entering the contact surface between the slide rail and the slider 2, thereby reducing equipment wear caused by impurities, improving the reliability and service life of the equipment, and by setting up the fixing mechanism 5, it is convenient to disassemble the oil storage box 302, and convenient to clean the impurities on the filter screen 304 and the oil storage box 302. The design of the fixing mechanism 5 allows for easy installation and removal of the oil reservoir 302, facilitating regular cleaning and maintenance of the filter screen 304 and the oil reservoir 302 by the user. This maintains the purity and lubrication effect of the lubricating oil. Furthermore, the cleaning mechanism 4 allows for the removal of dust adhering to the slide rail. When cleaning is required, the scraper 404 on one side of the slider 2 can be moved to contact the slide rail, allowing it to move along the direction of the slide rail and effectively remove dust and impurities from its surface. This design not only ensures the lubrication effect of the slide rail but also reduces wear and malfunctions caused by dust and impurities, improving the slide rail's service life and working accuracy. In addition, the cleaning mechanism 4 is simple and convenient to operate, allowing users to perform cleaning operations as needed, thus maintaining the cleanliness and lubrication of the slide rail.
