[0001] This utility model belongs to the technical field of self-lubricating guide rails, specifically relating to a self-lubricating precision guide rail for machine tools. Background Technology

[0002] Self-lubricating precision guideways for machine tools are advanced mechanical components designed to provide high-precision and low-friction linear motion. They are commonly found in CNC machine tools, automated production lines, and various industrial equipment. The self-lubricating material between the guideway and the slider creates a lubricating film at the contact surface, significantly reducing the coefficient of friction.

[0003] However, after prolonged use, the lubrication effect of the self-lubricating material on the guide rail will decrease, and the guide rail material cannot be replaced in time to restore the lubrication effect. Utility Model Content

[0004] The purpose of this invention is to provide a self-lubricating precision guide rail for machine tools, in order to solve the problem mentioned in the background art that the guide rail material cannot be replaced in a timely manner to restore the lubrication effect of the guide rail during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-lubricating precision guide rail for machine tools, comprising a guide rail body and a limiting strip installed on the inner wall of the rear end of the guide rail body;

[0006] A slider is provided on the upper side of the limiting strip;

[0007] An oil box is fixedly connected to the outer wall of the left end of the slider. The inner wall of the lower end of the oil box has openings near the left and right sides, and ball bearings are arranged inside the multiple openings.

[0008] Preferably, a filling pipe is fixedly connected to the outer wall of the left end of the oil box to deliver lubricating oil into the oil box through the filling pipe, and a fixing plug is snapped into the upper end of the filling pipe to seal the filling pipe.

[0009] Preferably, the oil box is fixedly connected to a partition plate to divide the internal space of the oil box into upper and lower layers.

[0010] Preferably, an oil inlet is fixedly connected to the lower outer wall of the partition plate to guide the upper lubricating oil to the lower layer, and an adjusting screw that engages with the oil inlet is provided inside the left outer wall of the oil box.

[0011] Preferably, a sealing ring is provided at the screw-in position of the adjusting screw and the oil box.

[0012] Preferably, a brush is provided on the right side of the slider, and a fixing clip is fixedly connected between the outer walls of the left and right ends of the brush.

[0013] Preferably, a fixing block is fixedly connected to the outer wall of the right end of the slider, and a fixing screw that screws into the slider to the left is provided on the right side of the fixing block.

[0014] Preferably, a housing is fixedly connected to the outer side of the guide rail body.

[0015] Preferably, a fixing block is fixedly connected inside the slider, and fixing frames are fixedly connected to the outer walls of both the front and rear ends of the fixing block, with pulleys provided inside the two fixing frames.

[0016] Preferably, the guide rail body is made of synthetic resin material.

[0017] Compared with the prior art, this utility model provides a self-lubricating precision guideway for machine tools, which has the following advantages:

[0018] 1. By installing an oil box, ball bearings, and a through-hole, when the lubrication effect of the guide rail body itself decreases while it is still in use, the corresponding lubricating oil can be added into the oil box. During the movement of the slider, the lubricating oil in the oil box can seep out through the through-hole, and the amount of lubricating oil seeping out is controlled by the ball bearings. This ensures that the guide rail body can maintain lubrication during operation, maintains the smooth operation of the guide rail system, reduces noise and vibration generated during movement, and thus improves machining accuracy and quality.

[0019] 2. By installing a brush, dust and debris on the guide rail can be effectively removed as the slider moves inside the guide rail body, keeping the sliding surface clean, reducing dirt accumulation, and helping to reduce friction between the slider and the guide rail. Clean contact surfaces reduce wear and increase the service life of the components. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1-3 The self-lubricating precision guide rail for machine tools shown includes a guide rail body 2 and a limiting strip 3 installed on the inner wall of the rear end of the guide rail body 2;

[0027] A slider 4 is provided on the upper side of the limiting strip 3. The slider 4 slides on the guide rail body 2, and the limiting strip 3 restricts the movement range of the slider 4 to ensure its stable operation on the guide rail and avoid damage caused by excessive movement. During the sliding process, the guide rail body 2 will secrete lubricant to assist the movement of the slider 4.

[0028] An oil box 8 is fixedly connected to the outer wall of the left end of the slider 4. The lower inner wall of the oil box 8 has openings 14 near the left and right sides. Each of the openings 14 contains a ball bearing 13. When the slider 4 moves on the guide rail 2, the lubricating oil attached to the openings 14 at the bottom of the oil box 8 will be discharged due to the rolling of the ball bearing 13, allowing the lubricating oil to flow out of the oil box 8. The ball bearing 13 is placed inside the opening 14, and its main function is to control the amount of lubricating oil flowing out. When the slider 4 moves, the ball bearing 13 helps to adjust the flow direction and speed of the lubricating oil, so that the amount of lubrication is appropriate and not too much or too little.

[0029] like Figure 3 As shown, a filling pipe 10 is fixedly connected to the outer wall of the left end of the oil box 8 to deliver lubricating oil into the oil box 8 through the filling pipe 10. A fixing plug 9 is snapped into the upper end of the filling pipe 10 to seal the filling pipe 10.

[0030] When adding lubricating oil into the oil box 8, first pull out the retaining plug 9, then deliver the corresponding lubricating oil into the oil box 8 through the filling pipe 10. After adding, insert the retaining plug 9 back into the filling pipe 10 to seal it.

[0031] like Figure 3As shown, a partition plate 15 is fixedly connected inside the oil box 8 to divide the internal space of the oil box 8 into upper and lower layers. An oil inlet 12 is fixedly connected to the lower outer wall of the partition plate 15 to guide the upper lubricating oil to the lower layer. An adjusting screw 11 is provided inside the left outer wall of the oil box 8 and is screwed with the oil inlet 12. A sealing ring is provided at the screwing position between the adjusting screw 11 and the oil box 8.

[0032] When the lubricating oil in the oil box 8 is needed for auxiliary lubrication, first rotate the adjusting screw 11 counterclockwise to lower the contact area between the adjusting screw 11 and the oil inlet 12. At this time, the lubricating oil on the upper layer of the partition plate 15 can enter the lower layer of the oil box 8 through the oil inlet 12. Then, the oil can be drained through the port 14. After lubrication is completed, tighten the adjusting screw 11 clockwise to seal the oil inlet 12.

[0033] like Figure 4 As shown, a brush 16 is provided on the right side of the slider 4, and a fixing clip 17 is fixedly connected between the outer walls of the left and right ends of the brush 16. A fixing block b19 is fixedly connected to the outer wall of the right end of the slider 4, and a fixing screw 18 is provided on the right side of the fixing block b19, which screws to the left and engages with the slider 4.

[0034] When the slider 4 slides on the guide rail, the brush 16 moves with the slider 4, cleaning the guide rail surface in real time and maintaining the cleanliness of the sliding surface. When the brush 16 is fixed, all the bristles of the brush 16 are clamped by the fixing clip 17, and then moved into the interior of the fixing block b19 for placement. The position of the brush 16 is then restricted by the fixing screw 18 passing through the fixing block b19 and the fixing clip 17.

[0035] like Figure 1 As shown, the outer shell 1 is fixedly connected to the outside of the guide rail body 2.

[0036] The outer shell 1 surrounds the outside of the guide rail body 2, providing protection.

[0037] like Figure 2 As shown, a fixed block a7 is fixedly connected inside the slider 4, and a fixed frame 6 is fixedly connected to the outer walls of both the front and rear ends of the fixed block a7. A pulley 5 is provided inside the two fixed frames 6.

[0038] The slider 4 achieves low-friction contact with the guide rail through the pulley 5 set on the guide rail body, thereby ensuring that the slider 4 slides smoothly on the guide rail. The design of the fixed block a7 and the fixed frame 6 ensures that the slider 4 has sufficient stability and load-bearing capacity during the movement, preventing shaking or displacement caused by high load or uneven movement.

[0039] like Figure 1 As shown, the guide rail body 2 is made of synthetic resin material.

[0040] Synthetic resin materials have the advantage of being lightweight, while also possessing good strength and rigidity, enabling them to withstand certain loads without easily deforming.

[0041] The implementation principle of this embodiment is as follows: Block 4 slides on the guide rail body 2, and the limiting strip 3 restricts the movement range of slider 4 to ensure its stable operation on the guide rail and avoid damage caused by excessive movement. During the sliding process, the guide rail body 2 will secrete lubricant to assist the movement of slider 4. When slider 4 moves on the guide rail 2, the port 14 at the bottom of the oil box 8 will discharge lubricating oil due to the rolling of the ball 13, allowing the lubricating oil to flow out of the oil box 8. The ball 13 is placed inside the port 14, and its main function is to control the amount of lubricating oil flowing out. When slider 4 moves, the ball 13 helps to adjust the flow direction and flow rate of lubricating oil so that the amount of lubrication is appropriate and not too much or too little.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
