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.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A dust and chip prevention device for CNC machine tool guideways includes a base 1. Two sets of guideways 2 are mounted on the upper part of the base 1 by fastening bolts 14. Slider 3 is movably sleeved on the outside of the two sets of guideways 2. The guideways 2 guide the movement trajectory of the slider 3. A protective plate 4 is fixed to the lower end of the slider 3. The protective plate 4 blocks the chips generated during the use of the CNC machine tool. A connecting plate 5 is fixed to the inner side of the lower part of the protective plate 4. An outer sleeve 6 is fixed to the lower end of the connecting plate 5. The outer sleeve 6 drives a cleaning brush 7 to be sleeved on the outside of the guideway 2, that is, the cleaning brush 7 is fitted and installed on the guideway 2. On the outside, the cleaning brush 7 cleans the dust and impurities adhering to the outside of the guide rail 2 to prevent the dust from interfering with the movement of the slider 3. The cleaning brush 7 is fixed at the lower end of the outer sleeve 6. A first gas delivery box 8 is installed on one side of the lower end of the protective plate 4. A second gas delivery box 9 is fixed at the lower end of the first gas delivery box 8. Ventilation pipes 10 are opened inside the first gas delivery box 8 and the second gas delivery box 9. High-pressure gas is sprayed through the second gas delivery box 9 and the ventilation pipes 10 through the first nozzle 12 and the second nozzle 13 to clean the dust on the outside of the guide rail 2 and the base 1.

[0024] Please see Figure 5The guide rail 2 includes a guide rail mounting seat 21 installed on the upper part of the base 1. A guide layer 22 is fixed on the upper part of the guide rail mounting seat 21. The guide rail 2 is generally I-shaped. The connection between the guide rail mounting seat 21 and the guide layer 22 is inclined. The guide rail 2 is installed on the upper part of the base 1 by fastening bolts 14 to ensure the stability of the guide rail 2 when it is limited on the upper part of the base 1. The guide rail 2 includes a guide rail mounting seat 21 and a guide layer 22. The guide layer 22 is installed on the upper end of the guide rail mounting seat 21. The upper cross section of the guide layer 22 is larger than the lower cross section of the guide rail mounting seat 21. That is, the guide layer 22 covers the upper part of the guide rail mounting seat 21. The guide layer 22 guides the slider 3 to move. After the guide layer 22 covers the upper part of the guide rail mounting seat 21, the guide layer 22 effectively prevents dust and debris from falling between the guide rail mounting seat 21 and the guide layer 22, thereby improving the dustproof and debris-proof effect of the equipment.

[0025] Please see Figure 1 The protective plate 4 is installed on the outside of the slider 3, and the two sides of the protective plate 4 extend to the outside of the base 1. The protective plate 4 is sleeved on the upper part of the slider 3. The workpiece is placed on the upper part of the slider 3. During the process of the slider 3 moving the workpiece and processing, debris will be generated. At the same time, the protective plate 4 blocks the debris and dust, preventing the dust and debris from falling directly between the slider 3 and the guide rail 2, which would cause interference when the slider 3 moves on the upper part of the guide rail 2.

[0026] Please see Figure 6 The outer sleeve 6 is fitted onto the outside of the guide rail 2. The cleaning brush 7 installed on the inner side of the outer sleeve 6 is fitted onto the outside of the guide rail 2. The cleaning brush 7 is installed on both sides of the slider 3. A connecting plate 5 is installed at the lower part of the protective plate 4 and inside the first gas delivery box 8. The connecting plate 5 drives the outer sleeve 6 to fit onto the outside of the guide rail 2. At the same time, the cleaning brush 7 is fixed on the inner side of the outer sleeve 6 and is fitted onto the outside of the guide rail 2. When the slider 3 moves on the upper part of the guide rail 2, the cleaning brush 7 scrapes and cleans the dust and debris adhering to the outside of the guide rail 2, so as to avoid the dust and debris interfering with the sliding of the slider 3.

[0027] Please see Figure 4 The second gas delivery box 9 protrudes downward from the lower end of the first gas delivery box 8. The second gas delivery box 9 is obliquely installed on both sides of the guide rail 2. The second gas delivery box 9 is installed at the lower part of the first gas delivery box 8. The first nozzle 12 and the second nozzle 13 are installed inside the second gas delivery box 9. The second gas delivery box 9 drives the first nozzle 12 and the second nozzle 13 to blow strong air obliquely to the side of the guide rail 2 and clean the dust and debris adhering to the side of the guide rail 2, thereby improving the dust and debris cleaning efficiency and improving the dust and debris prevention effect of the equipment.

[0028] Please see Figure 4 An air pump 11 is installed on the upper part of the protective plate 4 and on the upper part of the first gas delivery box 8. One set of air pump 11 is installed on each side of the upper part of the first gas delivery box 8. A ventilation pipe 10 is opened inside the first gas delivery box 8 and the second gas delivery box 9. The air pump 11 is installed on the upper end of the protective plate 4. The air pump 11 delivers gas into the ventilation pipe 10. At the same time, the high-pressure gas flows inside the ventilation pipe 10 and is transmitted outward through the first nozzle 12 and the second nozzle 13. During this process, the dust on the upper part of the guide rail 2 is cleaned by the first nozzle 12 and the second nozzle 13, thereby improving the dust removal efficiency of the equipment.

[0029] Please see Figure 3 A first nozzle 12 and a second nozzle 13 are respectively installed on the outside of the first gas delivery box 8 and the second gas delivery box 9. The first nozzle 12 is installed vertically to the horizontal plane, and the second nozzle 13 is installed at 45° to the horizontal plane. By installing the first nozzle 12 and the second nozzle 13 on the inside of the first gas delivery box 8 and the second gas delivery box 9, the first nozzle 12 blows gas vertically downwards, causing dust and debris to be discharged from the holes opened inside the base 1. At the same time, the second nozzle 13 blows out the dust accumulated on the guide rail 2 and the upper part of the base 1 at an angle. That is, during the movement of the slider 3, dust and debris are effectively discharged.

[0030] Working principle: In use, the guide rail 2 is installed on the upper part of the base 1, with the slider 3 sleeved on the outside of the guide rail 2. The guide rail 2 guides the movement trajectory of the slider 3. The upper end of the guide rail 2 is wider, and the outer side of the guide rail 2 is inclined to prevent dust and impurities from adhering to the outside of the guide rail 2. At the same time, the protective plate 4 is sleeved on the outside of the slider 3. During the cutting process of the part placed on the upper part of the slider 3 by the CNC machine tool, the protective plate 4 blocks the chips generated by cutting, preventing the chips from sliding onto the upper part of the guide rail 2, thus achieving a dust and chip prevention effect. The lower end of the protective plate 4... A connecting plate 5 is installed, which drives the dust removal brush 7 to be sleeved on the outside of the guide rail 2. When the slider 3 moves, the dust removal brush 7 further cleans the dust on the outside of the guide rail 2 during the movement of the slider 3. At the same time, the air pump 11 drives high-pressure gas to be delivered to the inside of the first nozzle 12 and the second nozzle 13. The first nozzle 12 and the second nozzle 13 further blow away the dust and impurities splashed onto the upper part of the guide rail 2 and the base 1. The blown-away dust and impurities are discharged through the holes opened inside the base 1, improving the cleaning efficiency of dust and debris, thereby achieving the effect of dust and debris prevention.
