Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a CNC machine tool guide rail with a dustproof and waterproof protection device. Background Technology

[0002] A CNC machine tool is a machine tool controlled by a computer program, combining machining and automation technologies. It can achieve automated machining according to a pre-programmed CNC program. CNC machine tools can perform complex machining tasks that are difficult for traditional machine tools, offering advantages such as high precision, high efficiency, and high repeatability. The guideway is one of the important components of a CNC machine tool, used to support and guide the moving parts of the machine tool along a predetermined trajectory during machining. Its main function is to provide stable and precise guidance to ensure the machine tool's motion accuracy and machining quality.

[0003] In existing technologies, CNC machine tool guideways are key devices used to support and guide the precise movement of machine tool components. They are typically made of precision-machined metal and, through contact with the machine tool's worktable and sliding parts, ensure the smooth and accurate movement of all moving parts during machining. The guideway system withstands various forces generated during machining through the relative sliding and rolling between the slider and the guideway, maintaining the machine tool's motion trajectory. CNC machine tool guideways are usually equipped with lubrication systems to reduce friction and extend service life. Some high-end guideways are also designed with sealing and protective measures to prevent dust, moisture, and other contaminants from entering, maintaining a high-precision working environment.

[0004] However, in actual use, some machine tool guideways are easily affected by external dust, moisture, oil and other contaminants during long-term use, especially in high-precision machining environments. These contaminants not only reduce the working accuracy of the guideways, but also cause wear and corrosion on the guideway surface, and even jamming, thereby affecting the service life and machining quality of the machine tool. In response to the above problems, a CNC machine tool guideway with a dustproof and waterproof protection device is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a CNC machine tool guide rail with a dustproof and waterproof protection device, aiming to improve the problem that some devices in the prior art cannot be dustproof and waterproof.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A CNC machine tool guide rail with a dustproof and waterproof protection device includes two fixed support blocks. A linear guide rail is fixedly connected to the outer side of the two fixed support blocks that is close to each other, i.e., the outer side that is away from the two fixed support blocks. A sliding block is slidably connected to the top of the linear guide rail. A protective mechanism is fixedly connected inside the sliding block. A sliding shell is fixedly connected to the outside of the sliding block. A cleaning mechanism is fixedly connected to the bottom side of the sliding shell.

[0014] The dust removal assembly includes an L-shaped fixing plate, which is externally fixedly connected to both sides of the sliding housing, and a cleaning sponge is externally fixedly connected to the L-shaped fixing plate.

[0015] As a further description of the above technical solution:

[0016] The external part of the rotating lead screw is slidably connected to the inside of the sliding housing, and the external part of the rotating lead screw is slidably connected to the inside of the sliding connecting block;

[0017] As a further description of the above technical solution:

[0018] The cleaning sponge slides on the outside of the linear guide rail on both sides, and the top of the linear guide rail is fixedly connected to the top of the absorbent sponge.

[0019] As a further description of the above technical solution:

[0020] The bottom of the cleaning cloth strip is slidably connected to the top of the linear guide rail, and the top of the linear guide rail is slidably connected to the bottom of the cleaning scraper.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the motor drives the lead screw to rotate, causing the sliding housing and sliding block to slide along the linear guide rail. The front and rear ends of the sliding block are equipped with dustproof rubber strips and dustproof rubber blocks, which effectively improves the sealing performance, prevents dust from entering, and protects the internal components.

[0030] 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.

[0031] Reference Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a CNC machine tool guide rail with a dustproof and waterproof protection device, comprising two fixed support blocks 1, which can be stably fixed to the bed of the CNC machine tool. A linear guide rail 8 is fixedly connected to the outer side of the two fixed support blocks 1 that is close to each other (i.e., the outer side furthest from the two fixed support blocks 1). This linear guide rail 8 has extremely high wear resistance and a low coefficient of friction, providing a precise and stable sliding track for a sliding block 9. A sliding block 9 is slidably connected to the top of the linear guide rail 8. The sliding block 9 has a rectangular block structure and internally has ball grooves adapted to the linear guide rail 8. The sliding block 9 can slide smoothly along the linear guide rail 8. The sliding block 9 has a protective mechanism fixedly connected inside. The protective mechanism includes a dustproof rubber strip 10, which is a thin rectangular strip that can effectively block dust, debris and other particulate impurities from entering the contact area between the sliding block 9 and the linear guide rail 8. The dustproof rubber strip 10 is fixedly connected to the outside of the sliding block 9. There are two dustproof rubber blocks 11 fixedly connected to the left and right sides of the inside of the sliding block 9. The dustproof rubber blocks 11 are square blocks that can further block dust when the sliding block 9 moves, and at the same time play a certain buffering role.

[0032] One of the fixed support blocks 1 is externally fixedly connected to a drive assembly, which includes a motor 2. When the motor 2 starts, it drives the rotating lead screw 3 to rotate. Through threaded transmission, the sliding housing 12 and the sliding connecting block 4 move linearly along the rotating lead screw 3. The motor 2 is externally fixedly connected to the outside of one of the fixed support blocks 1. The drive end of the motor 2 is fixedly connected to the rotating lead screw 3. The rotating lead screw 3 is a cylindrical structure with trapezoidal threads machined on its surface. The rotating lead screw 3 is externally slidably connected to the inside of the sliding housing 12 and the inside of the sliding connecting block 4. The drive assembly is fixedly connected to the sliding connecting block 4. The sliding connecting block 4 is a rectangular block structure. Connecting springs 5 ​​are fixedly connected to the bottom left and right sides of the sliding connecting block 4. The bottom of the two connecting springs 5 ​​is fixedly connected to a fixed connecting plate 6. The bottom of the fixed connecting plate 6 is glued with a water-absorbing sponge 7. The water-absorbing sponge 7 can effectively absorb water stains and oil stains around the guide rail, preventing them from entering the mating area of ​​the linear guide rail 8 and the sliding block 9, thus playing a role in waterproofing and cleaning.

[0033] Reference Figure 1 and Figure 2 The sliding block 9 is externally fixedly connected to a sliding shell 12. The sliding shell 12 is rectangular in shape and has good wear resistance and aesthetics. A cleaning mechanism is fixedly connected to one side of the bottom of the sliding shell 12. The cleaning mechanism includes a fixed connecting strip 13, which is a rectangular strip structure. The fixed connecting strip 13 is externally fixedly connected to one side of the bottom of the sliding shell 12. A cleaning cloth strip 14 is fixedly connected to the bottom of the fixed connecting strip 13, which can wipe the sliding shell 12 as it moves with the sliding block 9. The bottom of the cleaning cloth strip 14 is slidably connected to the top of the linear guide rail 8, and the top of the linear guide rail 8 is slidably connected to the bottom of the cleaning scraper 15. The bottom of the cleaning cloth strip 14 is slidably connected to the top of the linear guide rail 8, and the top of the linear guide rail 8 is slidably connected to the bottom of the cleaning scraper 15. The cleaning scraper 15 is fixedly connected to one side of the bottom of the sliding housing 12. The blade of the cleaning scraper 15 is finely polished and can scrape away stubborn stains on the surface of the linear guide rail 8, ensuring that the surface of the guide rail is clean.

[0034] Two dust removal components, including L-shaped fixing plates 16, are fixedly connected to the left and right sides of the outer side of the sliding housing 12. These are used to fix the cleaning sponge 17. The L-shaped fixing plates 16 are fixedly connected to the outer sides of the sliding housing 12. The cleaning sponge 17 is fixedly connected to the outer side of the L-shaped fixing plates 16, which can wipe the dust on the side of the sliding housing 12. At the same time, it can perform secondary interception and adsorption of dust entering between the sliding housing 12 and the linear guide rail 8, further improving the dustproof effect. The cleaning sponge 17 slides on the outer sides of the linear guide rail 8. The top of the linear guide rail 8 is fixedly connected to the top of the water-absorbing sponge 7.

[0035] Working principle: First, the motor 2 is started, causing the rotating screw 3 to rotate, which in turn drives the sliding housing 12 and the internal sliding block 9 to slide on the linear guide rail 8. Dustproof rubber strips 10 and dustproof rubber blocks 11 are installed at the front and rear ends of the sliding block 9 and the contact edges with the linear guide rail 8, which increases the sealing and prevents dust from affecting the internal components of the sliding block 9. At the same time, a sliding connecting block 4 can also slide outside the rotating screw 3, so that the connecting spring 5 at the bottom of the sliding connecting block 4 is pressed and placed above the fixed support block 1. When water is found on the linear guide rail 8, the sliding connecting block 4 is moved to slide on the rotating screw 3, so that the connecting spring 5 at the bottom of the sliding connecting block 4 is no longer pressed. The self-weight of the fixed connecting plate 6 and the water-absorbing sponge 7 stretches the connecting spring 5, thereby wiping the water on the linear guide rail 8 and preventing water from entering.

[0036] Meanwhile, a cleaning cloth strip 14 is provided at one end of the sliding housing 12, so that the dust on the linear guide rail 8 can be cleaned while the sliding housing 12 slides on the linear guide rail 8. A cleaning scraper 15 is provided at the other end of the sliding housing 12, so that the sliding housing 12 can clean the attachments on the linear guide rail 8 while sliding. A cleaning sponge 17 is placed inside the L-shaped fixing plate 16 at both ends of the sliding housing 12, so that the sliding housing 12 can drive the cleaning sponge 17 to clean both sides of the linear guide rail 8 while sliding.

[0037] 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.
