Description

Technical Field

[0001] This utility model relates to the field of linear guide equipment technology, specifically a linear guide with an automatic cleaning function. Background Technology

[0002] Linear guides are mechanical transmission components that use sliders and guide rails as core components and achieve linear motion through rolling elements (such as balls and rollers) or sliding friction. They provide high-precision, high-rigidity, and low-friction guidance and support for moving parts and are widely used in automation equipment, precision machine tools, robots, and other fields. They can ensure that the load moves smoothly and accurately back and forth along a fixed direction on the guide rail, effectively reducing resistance and wear during the motion process and improving the operating accuracy and stability of the equipment.

[0003] In practical use, linear guides often operate in complex environments, making them susceptible to dust, chips, and other impurities. These impurities adhere to the guide surface and rolling elements, increasing friction between the guide and the slider, leading to increased motion resistance and accelerated wear, which in turn affects the linear guide's motion accuracy and stability. Long-term accumulation of impurities can also clog the circulation channels of the rolling elements, causing them to jam, damaging the linear guide, and shortening its service life.

[0004] Therefore, we need to propose a linear guide with an automatic cleaning function. Utility Model Content

[0005] The purpose of this invention is to provide a linear guide rail with an automatic cleaning function, which can promptly remove dust, chips, and other impurities adhering to the surface of the guide rail, preventing the accumulation of impurities over a long period of time. This reduces the problem of increased friction between the guide rail and the slider caused by impurities, lowers motion resistance, and slows down the wear rate, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A linear guide rail with automatic cleaning function includes:

[0008] The main structure includes a linear guide rail and a base plate for mounting the linear guide rail. The linear guide rail includes a guide rail and a slider. The guide rail is mounted on the base plate, and the slider is mounted on the guide rail.

[0009] A cleaning mechanism is provided on both sides of the slider. The cleaning mechanism includes a side plate and a cleaning unit. The side plate is installed on both sides of the slider by screws, and the cleaning unit is located on the outside of the side plate for cleaning the guide rail.

[0010] Preferably, the cleaning unit includes a protrusion, the protrusion and the side plate are integrally formed, and the bottom of the protrusion and the side plate have a channel, the channel and the guide rail are adapted to each other and there is a gap so that the guide rail can pass through from the inside.

[0011] Preferably, the inner wall of the channel is provided with a brush, and the end of the brush abuts against the guide rail to remove dust.

[0012] Preferably, the inner wall of the channel is provided with a scraper, the edge of the scraper and the outer wall of the guide rail are separated by a gap, the scraper is located on the inner side of the channel, and the brush is located on the outer side of the channel.

[0013] Preferably, it also includes a dust collection mechanism installed at the bottom of the substrate. The dust collection mechanism includes a dust collection box, which is installed at the bottom of the substrate by fixing screws. The substrate has notches on both sides of the guide rail that communicate with the inner cavity of the dust collection box. Dust swept by the cleaning mechanism falls into the dust collection box through the notches for collection.

[0014] Preferably, a dust collection hood is provided on the outside of the notch, and the dust collection hood has a conical design that is larger at the top and smaller at the bottom.

[0015] Preferably, a sliding cover is slidably installed at the bottom of the dust collection box, and a lever is provided on the bottom surface of the sliding cover for pulling the sliding cover. Sliding grooves are symmetrically opened at the lower ends of the inner walls on both sides of the dust collection box, and the two sides of the sliding cover are slidably installed inside the two sets of sliding grooves respectively.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By setting cleaning mechanisms on both sides of the slider, the brushes on the inner wall of the channel in the cleaning unit continuously contact the guide rail as the slider moves along the guide rail. This can promptly remove dust, chips, and other dust impurities attached to the surface of the guide rail, preventing the accumulation of impurities over a long period of time. This reduces the problem of increased friction between the guide rail and the slider caused by impurities, lowers the movement resistance, and slows down the wear rate.

[0018] 2. The inner wall of the channel is equipped with both brushes and scrapers, with the scrapers located on the inner side of the channel and the brushes on the outer side. This design achieves a dual cleaning effect. The scrapers can first remove larger particles or stubborn impurities from the guide rail surface, while the brushes further refine and remove residual fine dust, thus improving the thoroughness of the cleaning and effectively ensuring the cleanliness of the guide rail surface.

[0019] 3. It reduces the interference of impurities on the relative motion between the guide rail and the slider, making the slider move more smoothly and stably on the guide rail. This effectively improves the motion accuracy and stability of the linear guide rail, ensuring that the equipment based on the linear guide rail can maintain high-precision processing or operation. It also reduces damage to the internal structure of the guide rail caused by impurities, reduces the frequency of maintenance and replacement, significantly extends the service life of the linear guide rail, and reduces the cost of use.

[0026] 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.

[0027] Please see Figure 1-3 This utility model provides a technical solution:

[0028] A linear guide 2 with an automatic cleaning function includes:

[0029] The main structure includes a linear guide rail 2 and a base plate 1 for mounting the linear guide rail 2. The linear guide rail 2 includes a guide rail 2 and a slider 3. The guide rail 2 is mounted on the base plate 1, and the slider 3 is mounted on the guide rail 2.

[0030] The cleaning mechanism is located on both sides of the slider 3. The cleaning mechanism includes a side plate 4 and a cleaning unit. The side plate 4 is installed on both sides of the slider 3 by screws. The cleaning unit is located on the outside of the side plate 4 for cleaning the guide rail 2.

[0031] Specifically, the cleaning unit includes a protrusion 6, which is integrally formed with a side plate 4. A channel 7 is formed at the bottom of the protrusion 6 and the side plate 4. The channel 7 is shaped to fit the guide rail 2 and has a gap to allow the guide rail 2 to pass through. A brush 8 is provided on the inner wall of the channel 7. The end of the brush 8 abuts against the guide rail 2 to remove dust.

[0032] In the main structure, the guide rail 2 is fixed to the base plate 1 to provide a guiding foundation, and the slider 3 slides along the guide rail 2 to achieve linear motion. The side plates 4 on both sides of the slider 3 are fixed with screws, and the channel 7 formed by the bottom of the side plates and the protrusion 6 is adapted to the shape of the guide rail 2 (gap 3-5mm). The brush 8 on the inner wall of the channel 7 moves with the slider 3 and contacts the surface of the guide rail 2, removing the attached dust by brushing off the dust through the friction of the brush bristles (nylon brush bristle diameter 0.1-0.2mm, brush density ≥30 bristles / mm²). The cleaning unit works synchronously by using the movement of the slider 3 itself, without the need for an additional power source. The brush 8 can remove dust and debris from the surface of the guide rail 2, preventing impurities from entering the gap between the slider 3 and the guide rail 2 and reducing frictional resistance.

[0033] For a preferred implementation, please refer to Figure 1-3 :

[0034] The inner wall of the channel 7 is provided with a scraper 9, and the edge of the scraper 9 is separated from the outer wall of the guide rail 2. The scraper 9 is located on the inner side of the channel 7, and the brush 8 is located on the outer side of the channel 7.

[0035] The scraper 9 (made of polyurethane with a Shore hardness of 70-80A) on the inner side of channel 7 has a gap of 0.1-0.3mm between its edge and the outer wall of guide rail 2. When the cleaning unit moves with slider 3, the brush 8 located on the outer side of channel 7 first cleans guide rail 2, and then the scraper 9 located on the inner side of channel 7 further scrapes guide rail 2 to remove residual fine dust.

[0036] Together with the brush 8, it forms a dual cleaning mechanism. First, the brush 8 removes larger impurities, and then the scraper 9 cleans up fine dust, which improves the thoroughness of cleaning and more effectively ensures the cleanliness of the guide rail 2 surface.

[0037] For a preferred implementation, please refer to Figure 1-5 :

[0038] It also includes a dust collection mechanism, which is installed at the bottom of the substrate 1. The dust collection mechanism includes a dust collection box 5, which is installed at the bottom of the substrate 1 by fixing screws. The substrate 1 has notches 10 on both sides of the guide rail 2 that communicate with the inner cavity of the dust collection box 5. The dust swept by the cleaning mechanism falls into the dust collection box 5 through the notches 10 for collection.

[0039] The notches 10 on both sides of the substrate 1 are connected to the bottom dust collection box 5. The impurities cleaned by the cleaning mechanism fall into the dust collection box 5 through the notches 10 under the action of gravity. The fixing screws ensure that the dust collection box 5 is firmly connected to the substrate 1.

[0040] To prevent impurities from scattering back into the working environment and causing secondary pollution after cleaning, the dust collection box 5 can collect impurities in a concentrated manner to prevent them from clogging the circulation channel 7 of the rolling element.

[0041] For a preferred implementation, please refer to Figure 1-5 :

[0042] A dust collection hood 11 is provided on the outside of the notch 10. The dust collection hood 11 has a conical design that is larger at the top and smaller at the bottom.

[0043] A conical dust collection hood 11 (cone angle 60°-90°) is set outside the notch 10 to expand the impurity collection range. The inclined inner wall guides the impurities to converge towards the notch 10, reducing the residue of impurities on the surface of the substrate 1.

[0044] The efficiency of guiding impurities to the dust collection box 5 is improved, ensuring that the impurities after cleaning fall into the dust collection box 5 quickly, further reducing the risk of secondary pollution.

[0045] For a preferred implementation, please refer to Figure 1-5 :

[0046] A sliding cover 12 is slidably installed at the bottom of the dust collection box 5. A lever 13 is provided on the bottom surface of the sliding cover 12 for pulling the sliding cover 12. Sliding grooves 14 are symmetrically opened at the lower end of the inner walls on both sides of the dust collection box 5. The two sides of the sliding cover 12 are slidably installed in the two sets of sliding grooves 14 respectively.

[0047] The sliding cover 12 at the bottom of the dust collection box 5 is slidably connected to the box body through the sliding grooves 14 on both sides. Pulling the lever 13 can open the sliding cover 12 along the sliding groove 14, making it easy to pour out the collected impurities. After closing, the sliding cover 12 fits tightly with the box body (sealing gap ≤ 0.5mm).

[0048] The cleaning operation of dust collection box 5 is simplified, and impurities can be removed without disassembling dust collection box 5, reducing equipment downtime for maintenance and improving maintenance convenience.

[0049] Among them, the brush 8 is made of nylon material, with a filament diameter of 0.2mm, a bristle length of 8mm, and a density of 40 bristles / mm². It is a round brush 8 with strong wear resistance (its service life is 3-5 times that of ordinary plastic brush 8), resistant to grease, and resistant to weak acids and alkalis (suitable for coolant and oily environments in machine tool and other scenarios). It also has moderate elasticity, which can closely fit the surface of the guide rail 2 (to ensure cleaning effect) without scratching the guide rail 2 due to excessive hardness (especially suitable for surface protection of precision guide rail 2).

[0050] The scraper blade 9 is made of polyurethane with a Shore hardness of 70-80A, which combines elasticity and rigidity. The elasticity ensures a tight fit between the edge of the scraper blade 9 and the surface of the guide rail 2 (contact pressure 0.2-0.5 N / cm), achieving a high chip removal rate. Its rigidity is sufficient to scrape away stubborn impurities such as metal shavings, and it has a low wear rate. The polyurethane is resistant to grease and coolant corrosion (suitable for industrial environments such as machine tools), and has a low coefficient of friction (≤0.3) when in contact with the chrome-plated surface of the guide rail 2, preventing scratches (surface roughness Ra≤0.4μm), perfectly matching the two-stage cleaning logic of "brush first, then scrape".

[0051] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
