Description

Technical Field

[0001] This utility model relates to the field of machine tool linear guide technology, and in particular to a machine tool linear guide with a dustproof structure. Background Technology

[0002] Machine tool linear guideways are key components used in machine tools and precision equipment to support and guide moving parts. They provide low-friction, high-precision linear motion and are widely used in CNC machine tools, automation equipment, and 3D printers. Linear guideways consist of a slider guideway, through which linear motion is achieved by the slider sliding on the track. Machine tool linear guideways are made of chrome steel to manufacture the guideway and slider, ensuring their rigidity, wear resistance, and load-bearing capacity.

[0003] When the machine tool is in a dirty environment, there is a lot of dust and dirt. These substances are easy to accumulate on the surface of the slide rail. After the seals of the slide rail age, they can no longer prevent dust and dirt from entering the slide rail. The contact surface between the slide rail and the slider will become uneven, increasing friction and causing the movement to be unsmooth, which will further affect the movement accuracy and slide rail life. Therefore, a machine tool linear slide rail with a dustproof structure is designed. Utility Model Content

[0004] The purpose of this utility model is to provide a machine tool linear guide rail with a dustproof structure to solve the problem mentioned in the background art that after the seal of the guide rail ages, it cannot prevent dust and dirt from entering the inside of the guide rail, and the contact surface between the guide rail and the slider becomes uneven, increasing friction and causing the movement to be unsmooth.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a machine tool linear guide with a dustproof structure, comprising a linear guide component and a slider, wherein the slider is slidably mounted on the top of the linear guide component, a wear-resistant washer is provided on one side of the slider, a sound-insulating washer is provided on one side of the wear-resistant washer, a scraper is provided on one side of the sound-insulating washer, and multiple threaded holes are provided on one side of each of the slider, the wear-resistant washer, the sound-insulating washer, and the scraper. Reinforcing plates are fixedly installed on both sides of the slider and the scraper, wherein two reinforcing rods are provided inside each of the two reinforcing plates, and a first positioning block is fixedly installed on one side of each of the two reinforcing plates.

[0006] As a preferred technical solution of this utility model, a plurality of limiting bolts are provided on one side of the scraper, and one end of the plurality of limiting bolts is respectively connected to the internal threads of a plurality of threaded holes.

[0007] As a preferred embodiment of this utility model, one end of each of the four reinforcing rods is threaded with a nut, and a second positioning block is fixedly installed on one side of each of the other two reinforcing plates.

[0008] As a preferred embodiment of this utility model, two first magnet strips are fixedly installed on one side of each of the two first positioning blocks, and two second magnet strips are fixedly installed on one side of each of the two second positioning blocks.

[0009] As a preferred embodiment of this invention, the four first magnet strips are magnetically connected to the four second magnet strips respectively.

[0010] In a preferred embodiment of this invention, the positions of the two adjacent reinforcing plates are corresponding.

[0011] In a preferred embodiment of this invention, the sound-insulating gasket is located between the wear-resistant gasket and the scraper, and the thickness of the sound-insulating gasket is less than the thickness of the wear-resistant gasket and the scraper.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model incorporates a wear-resistant washer, a sound-insulating washer, a scraper, reinforcing plates, reinforcing rods, and a nut. One side of the wear-resistant washer is tightly fitted to one side of the slider. The sound-insulating washer is then fitted onto one side of the wear-resistant washer, and the scraper is installed onto the same side. All three components are tightly fitted together. Multiple limiting bolts are threaded into the threaded holes to secure the components to the slider. The wear-resistant washer is made of rubber, which is wear-resistant and elastic, reducing friction between the scraper and the slider. The sound-insulating washer is made of polyurethane, which has good elasticity and shock absorption, reducing noise generated when the scraper removes dirt from the surface of the linear guide rail. After the reinforcing rod is inserted into two reinforcing plates, the nut is threaded onto one end of the reinforcing rod to limit and fix the four reinforcing plates, further ensuring the secure installation of all three components with the slider.

[0014] 2. This utility model is equipped with a first positioning block, a first magnet strip, a second positioning block, and a second magnet strip. When the slider slides on the top of the linear slide rail, the scraper slides on the surface of the linear slide rail. The scraper can remove the dust and dirt accumulated on the surface of the linear slide rail. Since the first magnet strip and the second magnet strip are magnetically connected, the stability of the installation between the corresponding two reinforcing plates is enhanced.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a machine tool linear guide rail with a dustproof structure:

[0022] Example 1:

[0023] like Figure 1-3 As shown, a machine tool linear guide with a dustproof structure includes a linear guide component 1 and a slider 2. The slider 2 is slidably mounted on the top of the linear guide component 1. A wear-resistant washer 3 is provided on one side of the slider 2, a sound-insulating washer 4 is provided on one side of the wear-resistant washer 3, and a scraper 5 is provided on one side of the sound-insulating washer 4. Multiple threaded holes 6 are provided on one side of the slider 2, the wear-resistant washer 3, the sound-insulating washer 4, and the scraper 5. Reinforcing plates 8 are fixedly installed on both sides of the slider 2 and the scraper 5, and two reinforcing rods are provided inside each of the two reinforcing plates 8. 9. One of the two reinforcing plates 8 is fixedly installed with a first positioning block 11 on one side. The wear-resistant washer 3 is made of rubber material, which is relatively wear-resistant and elastic, reducing the friction between the scraper 5 and the slider 2. The sound insulation washer 4 is made of polyurethane material, which has good elasticity and shock absorption effect, reducing the noise generated when the scraper 5 scrapes the dirt on the surface of the linear slide rail 1. After the reinforcing rod 9 is inserted into the two reinforcing plates 8, the nut 10 is threaded onto one end of the reinforcing rod 9, which can limit and fix the four reinforcing plates 8.

[0024] Example 2:

[0025] Based on Example 1, such as Figure 1 and Figure 4As shown, two first magnet strips 12 are fixedly installed on one side of each of the two first positioning blocks 11, and two second magnet strips 14 are fixedly installed on one side of each of the two second positioning blocks 13. The sound insulation gasket 4 is located between the wear-resistant gasket 3 and the scraper 5. The thickness of the sound insulation gasket 4 is less than the thickness of the wear-resistant gasket 3 and the scraper 5. When the slider 2 slides on the top of the linear slide rail 1, the scraper 5 slides on the surface of the linear slide rail 1. The scraper 5 can scrape off the dust and dirt accumulated on the surface of the linear slide rail 1. Since the first magnet strip 12 and the second magnet strip 14 are magnetically connected, the stability of the installation between the corresponding two reinforcing plates 8 is enhanced.

[0026] Working Principle: Linear guideways for machine tools are key components used to support and guide moving parts in machine tools and precision equipment. They provide low-friction, high-precision linear motion and are widely used in CNC machine tools, automation equipment, and 3D printers. A linear guideway includes a slider guide rail, where linear motion is achieved by the slider sliding on the rail. The linear guideway is made of chrome steel to manufacture the guide rail and slider, ensuring its rigidity, wear resistance, and load-bearing capacity. When the machine tool operates in a dirty environment, a large amount of dust and dirt are present. These substances easily accumulate on the surface of the guideway. After the seals of the guideway age, they cannot prevent dust and dirt from entering the interior of the guideway. The contact surface between the guideway and the slider becomes uneven, increasing friction and causing uneven movement, further affecting motion accuracy and the lifespan of the guideway. Therefore, a machine tool linear guideway with a dustproof structure is designed. One side of the wear-resistant washer 3 is tightly fitted to one side of the slider 2, and then the sound-insulating washer 4 is fitted and installed onto one side of the wear-resistant washer 3. (The text abruptly ends here, likely due to an incomplete translation or missing information.) 5 is installed on one side of the sound insulation washer 4, and the three fit tightly together. By using multiple limiting bolts 7 and threaded connections with threaded holes 6, the three can be installed with the slider 2. The wear-resistant washer 3 is made of rubber material, which is relatively wear-resistant and elastic, reducing the friction between the scraper 5 and the slider 2. The sound insulation washer 4 is made of polyurethane material, which has good elasticity and shock absorption effect, reducing the noise generated when the scraper 5 scrapes dirt off the surface of the linear slide rail 1. After the reinforcing rod 9 and the two reinforcing plates 8 are inserted, the nut 10 is threaded onto one end of the reinforcing rod 9, which can limit and fix the four reinforcing plates 8, further ensuring the firmness of the installation of the three with the slider 2. When the slider 2 slides on the top of the linear slide rail 1, the scraper 5 slides on the surface of the linear slide rail 1. The scraper 5 can scrape off the dust and dirt accumulated on the surface of the linear slide rail 1. Since the first magnet strip 12 and the second magnet strip 14 are magnetically connected, the stability of the installation between the corresponding two reinforcing plates 8 is enhanced.
