Description

Technical Field

[0001] The utility model relates to the technical field of linear guide rails, in particular to a linear guide rail slider. Background Art

[0002] Linear guide sliders are generally composed of guide rails, sliders, rolling elements and retainers. It is a rolling bearing that performs relative reciprocating linear motion. The rolling of the rolling elements between the slider and the guide rail can replace the direct sliding contact, and the rolling elements can achieve infinite circulation in the raceways and sliders.

[0003] Computer pattern machines are generally equipped with X-axis guides and Y-axis guides. In the prior art, both the X-axis and the Y-axis use two or more parallel guides to drive side by side to improve their load-bearing capacity. However, in actual use, it is found that multiple linear guides are inconvenient to assemble when used together, and the installation accuracy requirements are high. It is difficult to ensure that multiple guides are completely parallel, and the height is prone to errors, which can easily affect the smoothness of the operation of the linear guides. In addition, the use of multiple linear guides also increases costs, and the internal installation space of many devices is also limited; when using a single linear guide CN201921332350.2 wide linear guide slider pair for replacement, due to the large load, after the slider runs on the guide for a long time, the debris generated by the friction between the ball and the guide and the dust and impurities from the outside enter the oil body of the ball groove, resulting in a decrease in the performance of the linear guide and a reduction in the service life. Utility Model Content

[0004] The utility model aims to solve the problems existing in the above-mentioned prior art and provides a linear guide slider with good lubrication performance, which can improve the performance and service life of the linear guide.

[0005] The utility model adopts the following technical solution to solve the technical problem: a linear guide slider, which is applied to a computer pattern machine; it comprises a slider slidably mounted on the guide rail, end covers are mounted on both ends of the slider, a ball circulation channel is arranged on the slider and the end covers, a ball body is arranged in the ball circulation channel, the ball body slides in cooperation with a ball slide groove arranged on both sides of the guide rail, an oil nozzle connected to the ball circulation channel is arranged on the end cover, a main oil circuit connected to the oil nozzle is arranged on the slider, the main oil circuit is extended along the guide rail direction, oil branch circuits connected to the ball circulation channel are arranged at both ends of the main oil circuit, filter grooves are arranged on both sides of the inner wall in the middle of the main oil circuit, an inlet and an outlet connected to the main oil circuit are arranged on the filter groove, a guide plate is arranged on the inlet, and a filter screen is arranged on the outlet.

[0006] For further improvement, the guide rail is configured as a wide guide rail, the slider is configured as a wide slider adapted to the wide guide rail, and the main oil circuit is configured in the middle of the wide slider.

[0007] For further improvement, the guide rail is provided with a plurality of avoidance holes, and the avoidance holes penetrate through the guide rail.

[0008] For further improvement, an inclined guide plate is fixedly provided on the inlet of each of the two filter tanks, the two guide plates are centrally symmetrically provided, and an anti-blocking channel is provided between the two guide plates.

[0009] For further improvement, each filter tank is provided with at least one inlet and at least two outlets, and at least one inlet is provided between two adjacent outlets.

[0010] The beneficial effects of the utility model are:

[0011] Compared with the prior art, the utility model is provided with a wide guide rail and a matching wide slider on the guide rail of the computer pattern machine. The utility model has the advantage that the wide guide rail structure is adopted, and the assembly is more convenient and quick while maintaining a good load capacity. Because it is difficult to ensure that multiple guide rails are completely parallel and highly aligned, it is necessary to continuously adjust multiple guide rails during assembly, and errors are prone to occur during use, resulting in poor sliding. The utility model adopts a wide guide rail, which slides more smoothly and is more convenient to assemble.

[0012] The utility model ensures that the lubricating oil can be evenly delivered to the ball body by designing the oil nozzle and the main oil circuit extending along the guide rail on the slider, thereby reducing friction and wear. The sub-oil circuit design of the main oil circuit enables the lubricating oil to be better distributed to each ball body, and the setting of the filter groove effectively intercepts debris and impurities. Through the function of the guide plate and the filter screen, the oil body is further purified to prevent pollutants from entering the ball groove, thereby improving the performance of the linear guide and extending its service life. This design not only solves the problem of ball and guide rail wear caused by heavy loads, but also maintains the long-term stable operation of the slider and guide rail through an effective lubrication and cleaning system.

[0013] At the same time, the utility model sets a plurality of avoidance holes on the guide rail. During installation, since gears need to be installed below the computer pattern machine, the traditional method requires installation from below, which is very inconvenient. However, the utility model allows screws to pass through the avoidance holes and thus be installed above the guide rail, making assembly more convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] See attached Figure 1-4 :The present embodiment provides a linear guide slider, which is used on a computer pattern machine; it includes a slider 2 slidably installed on the guide rail 1, and end covers 3 are installed at both ends of the slider 2. A ball circulation channel 4 is provided on the slider 2 and the end cover 3. A ball body 5 is provided in the ball circulation channel 4. The ball body 5 slides with the ball slide grooves arranged on both sides of the guide rail 1. An oil nozzle 6 connected to the ball circulation channel 4 is provided on the end cover 3, and a main oil circuit 7 connected to the oil nozzle 6 is provided on the slider 2. The main oil circuit 7 is extended along the direction of the guide rail 1, and branch oil circuits 8 connected to the ball circulation channel 4 are provided at both ends of the main oil circuit 7. Filter grooves 9 are provided on the inner walls on both sides of the middle part of the main oil circuit 7. The filter groove 9 is provided with an inlet and an outlet connected to the main oil circuit 7. A guide plate 10 is provided on the inlet, and a filter screen 11 is provided on the outlet.

[0021] Working principle: By designing the ball circulation channel 4 and the end cover 3 on the slider 2, and setting the ball slide grooves on both sides of the guide rail 1, the circulation movement of the ball body 5 is realized, thereby ensuring the smooth sliding of the slider on the guide rail. The end covers 3 are installed at both ends of the slider 2, and the end covers 3 are provided with oil nozzles 6 to connect the ball circulation channel 4 to ensure that the added lubricating oil can smoothly enter and lubricate the ball body 5, reducing friction and wear.

[0022] In addition, the guide rail 1 of this embodiment is set as a wide guide rail, the slider 2 is set as a wide slider adapted to the wide guide rail, and the main oil circuit 7 is set in the middle of the wide slider. By setting a wide guide rail, on the one hand, a cavity space is provided for the main oil circuit, and on the other hand, the assembly of this embodiment can be made more convenient and quick while maintaining a good load capacity. Because when the prior art uses multiple guide rails, it is difficult to ensure that the multiple guide rails are completely parallel and highly aligned. During assembly, it is necessary to constantly adjust the multiple guide rails, and errors and offsets are prone to occur during use, resulting in poor sliding. The utility model uses a single wide guide rail, which slides more smoothly and is more convenient to assemble. Correspondingly, the cost of installation and production is also saved.

[0023] Further, see Figure 4This embodiment is suitable for use on computer pattern machines, especially on the Y-axis guide rails thereof. Figure 4 In the figure, the horizontal one is the X-axis guide rail 16, and the vertical guide rail 1 is the Y-axis guide rail. The guide rail 1 is installed on the X-axis guide rail and driven by the transmission belt 15 below. The guide rail 1 of this embodiment is provided with a plurality of avoidance holes 14, and the avoidance holes 14 are set through the guide rail 1. Through the above structure, during assembly, since the computer pattern machine has a transmission belt 15 and a gear that drives the transmission belt 15 and other structures below, during assembly, it can only be installed from the bottom, and the space is small and difficult to operate, and the assembly is troublesome. However, the avoidance holes 14 are provided in this embodiment, and the screws can be directly passed through the holes through the avoidance holes 14 for installation, which is convenient and quick, and greatly saves assembly time.

[0024] In this embodiment, the main oil circuit 7 provided on the slider 2 extends along the guide rail 1, and the lubricating oil is evenly distributed to each ball body 5 in the ball circulation channel 4 through the oil distribution circuit 8, so as to ensure the uniform lubrication effect of the entire slider. The filter tank 9 on both sides of the middle of the main oil circuit 7 filters the lubricating oil through the inlet 10 and the outlet 11, as well as the internal guide plate 10 and the filter screen 11, to prevent impurities from entering the ball circulation channel 4, keep the oil clean, and further improve the operation efficiency and service life of the slider. Specifically, when the slider 2 moves on the guide rail, the ball body 5 rolls inside the ball circulation channel 4, and the oil in the ball circulation channel 4 is pushed by the ball body 5 to enter the oil distribution circuit 8 at one end, flow through the main oil circuit 7, and flow back to the ball circulation channel 4 from the oil distribution circuit 8 at the other end. In the process of the oil flowing through the main oil circuit 7, it is introduced into the filter tank through the guide plate 10, and the impurities in the oil are filtered and deposited in the filter tank through the filter screen, thereby achieving the purification of the oil.

[0025] Overall, this technical solution effectively solves the problem of linear guide performance degradation caused by long-term operation and heavy loads through a carefully designed lubrication system and filtration mechanism, improves the operating accuracy of the slider and the stability of the equipment, and extends the service life of the linear guide.

[0026] An inclined guide plate 10 is fixedly arranged at the entrance of each of the two filter tanks 9. The two guide plates 10 are arranged symmetrically with respect to the center, and an anti-blocking channel 12 is arranged between the two guide plates 10. The symmetrical arrangement of the guide plates 10 helps to guide the bidirectionally flowing lubricating oil to smoothly enter the filter tank, while preventing the oil from directly impacting the filter screen 11, thereby reducing the direct impact of the oil on the filter screen and the possible damage. The design of the guide plates 10 also helps to disperse impurities in the oil, making it easier to be intercepted by the filter screen, thereby improving the filtering efficiency.

[0027] The anti-clogging channel 12 between the two guide plates 10 is an innovative design. It allows the oil to flow through the anti-clogging channel 12 if the filter is clogged or has a large resistance during the filtration process, ensuring the smooth flow of the oil and the long-term effective operation of the filtration system. This design reduces the problem of clogging of the filtration system caused by impurity accumulation, further ensures the lubrication effect of the slider and the guide rail, and extends the service life and maintenance cycle of the entire linear guide system.

[0028] Embodiment 2, as attached Figure 3 As shown, on the basis of embodiment 1, at least one inlet and at least two outlets are provided on each filter tank 9, and at least one inlet is provided between two adjacent outlets. This configuration optimizes the flow path and filtering efficiency of the lubricating oil. At least one inlet is provided between two adjacent outlets. Such a design allows the lubricating oil to first pass through the middle inlet when entering the filter tank 9, and then be diverted to the outlets on both sides. Such a distribution helps to reduce the direct impact of the oil flow on the filter screen 11, and also allows the impurities in the oil to have more opportunities to be intercepted by the filter screen.

[0029] In addition, the provision of multiple outlets ensures that the lubricating oil can flow out of the filter tank 9 evenly and effectively even under high-load working conditions, maintaining the lubrication state between the slider 2 and the guide rail 1, and facilitating maintenance operations. A sealing cover 13 is provided on the top of the slider 2, and the sealing cover is fixedly connected to the slider thread. In the linear guide slider system, the sealing cover 13 designed on the top of the slider 2 has important practical value. The design of the sealing cover 13 takes into account the convenience of processing and cleaning. When the filter tank needs to be maintained or cleaned, the sealing cover can be easily removed, so that the internal filter components such as the guide vane 10 and the filter screen 11 can be easily accessed and replaced. Such a design reduces the complexity of maintenance work and improves maintenance efficiency, while also reducing the risk of equipment failure due to improper cleaning.

[0030] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
