Description

Technical Field

[0001] This utility model belongs to the field of guide rail technology, and in particular relates to a sliding guide rail. Background Technology

[0002] Sliding guides are a common type of guide mechanism used in machine tools or other equipment. They provide support and guidance for the movement of the mechanism by having a slider slide above it.

[0003] Regarding sliding guideways, a search reveals that Chinese utility model patent CN221415940U discloses a machine tool guideway lubrication device, such as... Figure 1 As shown, it mainly includes a lower guide rail a, a slider b that slides on the lower guide rail a, the sliding cross-section of the lower guide rail a and the slider b is convex, a lubrication cavity is provided on the lower side of the lower guide rail a along its length, a plurality of oil leakage holes are provided on the sliding surface of the lower guide rail a, and a squeezing block that can seal the lubrication cavity is provided at the bottom of the lubrication cavity, and the squeezing block is connected to a drive mechanism (including a motor) that can drive it to move up and down.

[0004] In the implementation of existing sliding guides with similar technical solutions, there are areas for improvement: the lubrication chamber is set entirely on the lower guide rail, and the lubricating oil in the lubrication chamber can be squeezed out by the drive mechanism to achieve the lubrication function. However, the above device requires a motor-type drive mechanism, which increases the overall cost of the lubrication structure. In addition, the lubrication chamber is set entirely on the lower guide rail, especially when the lower guide rail is long, which increases the size of the lubrication chamber and the extrusion block, thus increasing the overall manufacturing and processing costs. Utility Model Content

[0005] In view of the shortcomings and defects of the existing technology, the purpose of this utility model is to provide a sliding guide rail, which solves the problem of increased overall cost caused by setting the lubrication cavity on the lower guide rail in the existing guide rail.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a sliding guide rail, including a lower guide rail and a slider, wherein the lower guide rail includes a base plate, a support column and a sliding column, the bottom of the support column is fixedly connected to the base plate and the top of the support column is fixedly connected to the sliding column, a hard rubber layer is detachably fixed inside the slider, the hard rubber layer is slidably connected to the sliding column, a lubrication cavity is provided inside the slider, an injection hole is provided at the upper part of the lubrication cavity, a groove is provided at the position where the injection hole is provided on the upper part of the slider, a drip hole is provided at the lower part of the lubrication cavity to allow the hard rubber layer to penetrate out, a reinforcing strip is embedded in the hard rubber layer, and a first connecting hole is provided at each of the four corners of the upper part of the slider.

[0007] As a further improvement of this utility model, a rolling ring is embedded and fixed at the bottom of the hard rubber layer, and multiple balls are rolled and connected inside the rolling ring, with the bottom of the balls contacting the sliding column.

[0008] As a further improvement of this utility model, the base plate is provided with a plurality of second connection holes.

[0009] As a further improvement of this utility model, the slider is glued to the hard rubber layer.

[0010] As a further improvement of this utility model, an injection tube is threadedly connected to the upper part of the injection hole.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] 1. By setting a lubrication cavity inside the slider, with an injection hole at the upper part of the lubrication cavity and a drip hole at the lower part of the lubrication cavity, lubricating oil or grease can be injected through the injection hole and then dripped onto the lower guide rail by gravity. Compared with the existing technology of setting the lubrication cavity on the lower guide rail and setting a drive mechanism inside the lubrication cavity, the structure is simple, the operation is convenient, and the overall manufacturing cost can be saved.

[0013] In addition, by detachably connecting a hard rubber layer to the inside of the slider, the hard rubber layer is slidably connected to the sliding column. The hard rubber layer can prevent the slider from being directly worn. When the hard rubber layer wears out, the rubber layer can be replaced directly, saving maintenance costs.

[0014] In addition, by providing a groove on the upper part of the slider at the location where the injection hole is set, the top of the injection hole is lower than the top surface of the slider, thus avoiding interference between the structure connected to the injection hole and the equipment on the upper part of the slider.

[0015] In addition, by embedding reinforcing strips within the hard rubber layer, the overall stability of the hard rubber layer can be increased.

[0016] 2. By embedding and fixing a rolling ring at the bottom of the hard rubber layer, and rolling multiple balls connected in the rolling ring, the bottom of the balls contacting the sliding column, thereby reducing the friction between the hard rubber layer and the lower guide rail.

[0017] 3. An injection tube, which can be a flexible hose, is threaded onto the upper part of the injection hole to facilitate the injection of lubricating oil or grease. Attached Figure Description

[0024] The following is combined with Figure 2-4 The present invention will be described in further detail below. For clarity, only the structures relevant to the inventive features of the present invention are shown in the figures.

[0025] For ease of description, the coordinate system is defined as follows: Figure 2 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0026] This utility model discloses a sliding guide rail. (Refer to...) Figure 2 A sliding guide rail includes a lower guide rail 1 and a slider 2. The lower guide rail 1 includes a base plate 101, a support column 102, and a sliding column 103. The bottom of the support column 102 is fixedly connected to the base plate 101, and the top is fixedly connected to the sliding column 103. The base plate 101 has multiple second connection holes 11 for mounting the base plate 101 on a machine tool or other equipment. A hard rubber layer 3 is detachably fixed inside the slider 2. Specifically, the slider 2 and the hard rubber layer 3 are glued together, that is, the slider 2 and the hard rubber layer 3 are bonded together by adhesive. The inner side of the hard rubber layer 3 is slidably connected to the sliding column 103. Figure 4 As shown, the slider 2 has a lubrication cavity 12, an injection hole 4 at the upper part of the lubrication cavity 12, a groove 5 at the location of the injection hole 4 on the upper part of the slider 2, and a drip hole 6 at the lower part of the lubrication cavity 12 through which the hard rubber layer 3 can penetrate. A reinforcing strip 7 is embedded in the hard rubber layer 3, thereby increasing the overall stability of the hard rubber layer 3. Figure 2 As shown, each of the four corners of the upper part of the slider 2 is provided with a first connecting hole 8.

[0027] In addition, such as Figure 2As shown, an injection tube 13 is threadedly connected to the upper part of the injection hole 4. The injection tube 13 can be a flexible hose that can extend from one side of the groove 5 to facilitate the injection of lubricating oil or grease, or a plug can be directly connected to the injection hole 4 (not shown in the attached figure). In addition, by providing a groove 5 on the upper part of the slider 2 at the location where the injection hole 4 is set, the top of the injection hole 4 is lower than the top surface of the slider 2, avoiding interference between the structure connected to the injection hole 4 and the equipment on the upper part of the slider 2.

[0028] In addition, such as Figure 2 Figure 3 and Figure 4 As shown, a rolling ring 9 is embedded and fixed at the bottom of the hard rubber layer 3. Multiple balls 10 are rolled and connected inside the rolling ring 9. The bottom of the balls 10 contacts the sliding post 103, thereby reducing the friction between the hard rubber layer 3 and the lower guide rail 1.

[0029] This invention provides a lubrication cavity 12 inside the slider 2, with an injection hole 4 at the upper part of the lubrication cavity 12 and a drip hole 6 at the lower part. After lubricating oil or grease is injected through the injection hole 4, the lubricating oil or grease can drip onto the lower guide rail 1 by gravity. Compared with the prior art, which sets the lubrication cavity 12 on the lower guide rail 1 and sets a driving mechanism inside the lubrication cavity 12, this invention has a simple structure, is easy to operate, and can save overall manufacturing costs.

[0030] In addition, by detachably connecting the hard rubber layer 3 inside the slider 2, the hard rubber layer 3 is slidably connected to the sliding column 103. The hard rubber layer 3 can prevent the slider 2 from being directly worn. When the hard rubber layer 3 is worn, the rubber layer can be directly replaced, saving maintenance costs.
