Description

Technical Field

[0001] The present invention relates to the technical field of ball screws, and particularly to a reversible ball screw with small edge load. Background Art

[0002] Ball screws have the advantages of high precision, high efficiency and high reliability, and are widely used in various machinery and automation equipment. Ball screws mainly consist of components such as screws, nuts and balls. When the screw or nut rotates relative to each other, the balls roll between the raceways in the nut and the thread grooves of the screw to achieve the conversion of linear motion or rotational motion.

[0003] During the use of ball screws, dust particles in the surrounding environment may enter the working area of the ball screw and then become embedded between the raceways and the balls, resulting in increased wear of the ball screw. The cleaning components of traditional ball screw systems, such as scraping plates and sealing rings, will lose their cleaning effect due to continuous dust accumulation on the components during long-term use, thus requiring frequent replacement of the cleaning components.

[0004] Patent CN219673209U discloses a precision ball screw with dust-proof function. The above patent realizes the cleaning of dust on the surface of the screw body, improves the dust-proof effect of the travel sleeve, and avoids dust in the ball groove from affecting the smooth rotation of the steel balls and the running accuracy of the travel sleeve.

[0005] The above patent uses brush strips to clean the dust on the surface of the screw body, and the sealing strip isolates dust from entering the ball groove, solving the problem that the dust on the screw surface is rolled into the travel sleeve and affects the smoothness and accuracy of the travel sleeve movement. However, there is still room for optimization in the treatment of the dust on the screw surface after cleaning. This application realizes the treatment of the dust on the cleaning device and solves the problem that the dust accumulated on the cleaning device wears the ball screw.

[0006] Therefore, this application proposes a reversible ball screw with small edge load that realizes the treatment of the dust on the cleaning device. Summary of the Invention

A dust cleaning component is provided on the screw rod body 31. The dust cleaning component includes: a dust removal sleeve 2; a nut body 1 is movably sleeved on the screw rod body 31. A screw groove 32 is opened on the screw rod body 31. Dust removal sleeves 2 are symmetrically and fixedly connected to the outer wall of the nut body 1. A cleaning plate 6 is fixedly connected to the inner wall of the dust removal sleeve 2. The dust removal sleeve 2 is connected to a disc 13 through a first rotating shaft 15. Annular tooth plates 14 are equidistantly and fixedly connected to the outer wall of the disc 13. A moving tooth plate 4 is meshingly installed on the side wall of the annular tooth plate 14. The disc 13 is connected to an adjusting arm 11 through a rotating column 12. The adjusting arm 11 is connected to a moving arm 9 through a moving column 19. A rotating arm 8 is rotatably connected to the side wall of the moving arm 9. An arc plate 7 is fixedly connected to the side wall of the rotating arm 8; A rolling bearing 74 is fixedly installed on the outer wall of the screw rod body 31.

A cross block 3 is fixedly connected to the bottom of the outer wall of the moving tooth plate 4. The cross block 3 is movably sleeved on the outer wall of the nut body 1; Anti-deviation plates 17 are symmetrically and fixedly connected to the outer wall of the cleaning plate 6. An anti-deviation groove 10 is opened on the outer wall of the moving arm 9. The anti-deviation plates 17 are movably sleeved on the outer wall of the anti-deviation groove 10. A passage groove 20 is opened on the outer wall of the cleaning plate 6. The passage groove 20 is movably sleeved on the outer wall of the moving column 19. Limit plates 16 are symmetrically and fixedly connected to the outer wall of the cleaning plate 6. The limit plates 16 are symmetrically installed on both sides of the moving arm 9. The side wall of the moving arm 9 is slidably connected to the limit plates 16.

[0025] Further, the drive motor 73 drives the lead screw body 31 to rotate through the coupling 75. The rolling bearing 74 rotates on the rolling bearing 74. The nut body 1 moves horizontally on the lead screw body 31. The lead screw body 31 drives the dust removal sleeve 2 to move. The dust removal sleeve 2 drives the cleaning plate 6 to move. The cleaning plate 6 cleans the dust in the thread groove 32 on the lead screw body 31 to prevent dust from entering the inside of the lead screw body 31 and wearing the balls. During the process of the cleaning plate 6 cleaning the dust, the dust will gradually accumulate and adhere to the top of the cleaning plate 6. The dust removal sleeve 2 drives the first rotating shaft 15 and the disc 13 to move. The disc 13 moves along the cross block 3. The moving tooth plate 4 meshes with the annular tooth plate 14, causing the moving tooth plate 4 to drive the annular tooth plate 14 to rotate. The annular tooth plate 14 drives the disc 13 to rotate. The disc 13 drives the rotating column 12 to rotate. The rotating column 12 drives the adjusting arm 11 to move. The adjusting arm 11 drives the moving arm 9 to move through the moving column 19. The moving column 19 moves along the passage groove 20.

The moving arm 9 drives the rotating arm 8, and the rotating arm 8 drives the arc-shaped plate 7. As the disc 13 rotates, the arc-shaped plate 7 moves repeatedly in the vertical direction of the cleaning plate 6, so that the arc-shaped plate 7 disperses the dust accumulated on the top of the cleaning plate 6, preventing the dust from accumulating between the cleaning plate 6 and the thread groove 32, resulting in an increase in the friction force between the cleaning plate 6 and the lead screw body 31, and preventing excessive dust accumulation from wearing the lead screw body 31 by the cleaning plate 6, ensuring the effect of dust cleaning.

[0026] Please refer to Figure 2 , Figure 3 and Figure 4 As shown in A dust removal assembly is provided on the disc 13. The dust removal assembly includes: a second rotating shaft 24, a third rotating shaft 27, and a fan 30. The disc 13 is fixedly sleeved on the outer wall of the first rotating shaft 15. A dust removal sleeve 2 is movably sleeved on the outer wall of the first rotating shaft 15. A first bevel gear 22 is fixedly connected to the side wall of the first rotating shaft 15. A second bevel gear 23 is meshingly installed on the side wall of the first bevel gear 22. A second rotating shaft 24 is fixedly connected to the side wall of the second bevel gear 23. A third bevel gear 25 is fixedly connected to the side wall of the second rotating shaft 24. A fourth bevel gear 26 is meshingly installed on the side wall of the third bevel gear 25. A fifth bevel gear 28 is connected to the fourth bevel gear 26 through the third rotating shaft 27. A fan 30 is provided in the dust removal sleeve 2. The fan 30 is connected to a sixth bevel gear 29 through a rotating shaft. The fifth bevel gear 28 meshes with the sixth bevel gear 29.

[0027] Further, the lead screw body 31 drives the dust removal sleeve 2 to move. The cleaning plate 6 cleans the dust in the thread groove 32 of the lead screw body 31. The dust removal sleeve 2 drives the first rotating shaft 15 and the disc 13. Under the action of the moving tooth plate 4, the moving tooth plate 4 drives the annular tooth plate 14, the disc 13, and the first rotating shaft 15 to rotate. The disc 13 drives the rotating column 12, the adjusting arm 11, the moving column 19, the moving arm 9, the rotating arm 8, and the arc plate 7, so that the arc plate 7 disperses the dust accumulated on the top of the cleaning plate 6. At the same time, the first rotating shaft 15 drives the first bevel gear 22 to rotate. The first bevel gear 22 drives the second bevel gear 23 to rotate. The second bevel gear 23 drives the second rotating shaft 24. The second rotating shaft 24 drives the third bevel gear 25 to rotate. The third bevel gear 25 drives the fourth bevel gear 26. The fourth bevel gear 26 drives the fifth bevel gear 28. The fifth bevel gear 28 drives the sixth bevel gear 29. The sixth bevel gear 29 drives the fan 30 through a rotating shaft. The fan 30 blows the dust dispersed on the cleaning plate 6, so that the dust moves from the cleaning plate 6 to the ventilation opening 5, thereby preventing the dispersed dust from accumulating on the cleaning plate 6. The dust-proof net 18 prevents the dust from dispersing onto the fan 30 and affecting the blowing effect of the fan 30.

[0028] Please refer to Figure 2 、 Figure 5, an embodiment provided by the present invention: a reversible ball screw with small edge load, a nut body 1 is movably sleeved on the screw body 31, a screw groove 32 is formed on the screw body 31, dust removal sleeves 2 are symmetrically and fixedly connected to the outer wall of the nut body 1, a cleaning plate 6 is fixedly connected to the inner wall of the dust removal sleeve 2, the dust removal sleeve 2 is connected to a disc 13 through a first rotating shaft 15, annular tooth plates 14 are equidistantly and fixedly connected to the outer wall of the disc 13, a moving tooth plate 4 is meshingly installed on the side wall of the annular tooth plate 14, the disc 13 is connected to an adjusting arm 11 through a rotating column 12, the adjusting arm 11 is connected to a moving arm 9 through a moving column 19, a rotating arm 8 is rotatably connected to the side wall of the moving arm 9, and an arc-shaped plate 7 is fixedly connected to the side wall of the rotating arm 8; An adjustment assembly is provided on the cleaning plate 6, and the adjustment assembly includes: an inclined plane body 34, a second spring 38, and an inclined plane stopper 40; a third spring 43 is fixedly connected to the inner wall of the cleaning plate 6, a displacement block 39 is fixedly connected to the side wall of the third spring 43, second springs 38 are symmetrically and fixedly connected to the outer wall of the displacement block 39, the inclined plane body 34 is fixedly connected to the outer wall of the second spring 38, the displacement block 39 is movably sleeved on the outer wall of the inclined plane body 34, a displacement groove 21 is formed on the outer wall of the cleaning plate 6, the displacement groove 21 is movably sleeved on the outer wall of the lifting column 33, the rotating arm 8 is fixedly connected to the side wall of the lifting column 33, inclined plane stoppers 40 are symmetrically and fixedly connected to the inner wall of the cleaning plate 6, a rubber pad 35 is fixedly connected to the side wall of the arc-shaped plate 7, the rubber pad 35 is in contact with the cleaning plate 6, a second baffle 46 is fixedly connected to the outer wall of the rotating arm 8, a first baffle 45 is fixedly connected to the outer wall of the moving arm 9, the rotating arm 8 is movably sleeved on the outer wall of the rotating shaft 47, the moving arm 9 is movably sleeved on the outer wall of the rotating shaft 47, and a torsion spring 44 is movably installed on the outer wall of the rotating shaft 47, and the torsion spring 44 is in contact with the first baffle 45 and the second baffle 46.

[0029] Furthermore, the lead screw body 31 drives the dust removal sleeve 2, and the cleaning plate 6 cleans the dust in the screw groove 32. The dust removal sleeve 2 drives the first rotating shaft 15 and the disc 13. Under the action of the moving tooth plate 4, the moving tooth plate 4 drives the annular tooth plate 14 and the disc 13 to rotate. The disc 13 drives the rotating column 12, the adjusting arm 11, the moving column 19, the moving arm 9, the rotating arm 8, and the arc plate 7. During the movement of the rotating arm 8 and the arc plate 7, the rotating arm 8 drives the lifting column 33 to move in the displacement groove 21. When the moving arm 9 approaches the disc 13, the lifting column 33 drives the inclined plane body 34, the second spring 38, and the displacement block 39 to move. The displacement block 39 compresses the third spring 43, and the inclined plane body 34 gradually contacts the inclined plane stopper 40, causing the inclined plane stopper 40 to drive the inclined plane body 34 to compress the inclined plane body 34. The side area of the inclined plane body 34 in contact with the lifting column 33 gradually decreases until the lifting column 33 no longer contacts the side of the inclined plane body 34. The lifting column 33 moves onto the inclined plane of the inclined plane body 34. At this time, the third spring 43 returns from the compressed state to the original state, and the third spring 43 drives the inclined plane body 34, the second spring 38, and the displacement block 39 to reset. During this process, the torsion spring 44 on the rotating shaft 47 applies an elastic force to the first baffle 45 and the second baffle 46, so that the second baffle 46 applies a pressure to the rotating arm 8, the rotating arm 8 applies a pressure to the arc plate 7, and the arc plate 7 applies a pressure to the rubber pad 35, causing the rubber pad 35 to be in close contact with the cleaning plate 6, so that the arc plate 7 and the rubber pad 35 can drive the dust accumulated and attached to the top of the cleaning plate 6 to the lower part of the cleaning plate 6; When the moving arm 9 moves away from the disc 13, the lifting column 33 moves on the inclined plane of the inclined plane body 34. Under the action of the elastic force of the second spring 38 and the inclined plane of the inclined plane body 34, the lifting column 33 gradually drives the rotating arm 8 to overcome the elastic force of the torsion spring 44, causing the rotating arm 8 to rotate. The rotating arm 8 drives the arc plate 7 and the rubber pad 35 to gradually move away from the cleaning plate 6, so that when the moving arm 9 drives the rotating arm 8, the arc plate 7 and the rubber pad 35 move towards the top of the cleaning plate 6, the rubber pad 35 will not contact the cleaning plate 6, thus preventing the arc plate 7 and the rubber pad 35 from bringing the dust back to the top of the cleaning plate 6 or failing to disperse the accumulated dust.
