[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Specific implementation examples are given below.

[0033] Please see Figures 1-8This application provides an aluminum wheel grinding and polishing device, including a worktable 1; the worktable 1 is equipped with a control panel, which is electrically connected to the electrical components in the device. The control panel contains a highly integrated controller for easy user control of the device. A groove 2 is provided on the worktable 1, and a lifting mechanism is provided inside the worktable 1. The lifting mechanism is used to raise and lower the polishing support 8. With the structural design of the auxiliary flipping mechanism, it is easy to flip the aluminum wheel for grinding. The lifting mechanism includes a first motor 3 located at the bottom inner side of the worktable 1. The first motor 3 is a type of servo motor that can achieve forward and reverse rotation. A threaded rotating rod 4 is provided at the output end of the first motor 3. A pusher 5 is threadedly connected to the first motor 3. A lifting plate 6 is provided above the pusher 5. The lifting plate 6 is adapted to the groove 2. A set of side frames 7 is provided inside the worktable 1. The two sides of the push frame 5 are slidably connected to the corresponding side frames 7. A polishing support 8 is provided on the push frame 5. The first motor 3 drives the threaded rotating rod 4 to rotate. At this time, the two sides of the push frame 5 slide on the side frames 7, so that the push frame 5 moves up and down on the threaded rotating rod 4, thereby pushing the polishing support 8. A wheel adjustment and positioning mechanism is provided on the table surface of the polishing support 8, which can position aluminum wheels of different diameters. A dust handling mechanism is provided on the polishing support 8 to prevent dust generated during wheel polishing from drifting in the polishing area and affecting the working environment. An auxiliary flipping mechanism is provided on the upper rear side of the worktable 1 to flip the aluminum wheel and polish the other side of the aluminum wheel, improving the polishing efficiency of the aluminum wheel. A polishing mechanism is provided on the upper front side of the worktable 1 to effectively polish the aluminum wheel.

[0034] Furthermore, such as Figure 1 and Figure 5As shown, the wheel adjustment and positioning mechanism includes a set of base frames 9 fixedly mounted above the polishing support 8. A set of slide rails 10 are fixedly mounted parallel to each other on the two base frames 9, with a set of sliding parts 11 slidably connected to each slide rail 10. Support plates 12 are fixedly mounted above the corresponding front and rear sliding parts 11. A set of positioning clips are symmetrically arranged above the support plates 12. A central support 13 is fixedly mounted in the middle of the polishing support 8. A central rotating plate 14 is rotatably mounted on the central support 13. Hinges 15 are hinged to the central rotating plate 14, and the other end of each hinge 15 is hinged to the support plate 12. Support members 16 are fixedly mounted on both sides above the polishing support 8. An electric push rod 17 is fixedly mounted above the support member 16, and the ends of the electric push rod 17 are fixed to the support plate 12 on the right side. The connection involves two synchronous electric push rods 17. By controlling the operation of the electric push rods 17, the right support plate 12 is pushed. At the same time, the slide 11 below the right support plate 12 slides on the slide rail 10, and the corresponding hinge 15 on it rotates the central rotating plate 14 on the central support platform 13. At this time, the hinge 15 on the other side pushes the left support plate 12 on the slide rail 10, thereby driving the wheel adjustment and positioning mechanism. This allows the four positioning clips to be positioned synchronously on the aluminum wheel. When polishing the inner wall of the wheel, the four positioning clips are driven to position the outer wall of the wheel. When polishing the outer wall of the wheel, the four positioning clips are driven to position the inner wall of the wheel. This improves the flexibility and practicality of the wheel adjustment and positioning mechanism.

[0035] Furthermore, such as Figure 5 As shown, the two hinge frames 15 are symmetrically arranged about the axis of the central rotating plate 14, which can synchronously drive the two support plates 12 on the left and right sides, so that the four positioning clips can synchronously position the aluminum wheel and improve the effect of fixing the aluminum wheel.

[0036] Furthermore, such as Figure 5 As shown, the positioning clip includes a positioning post 18 fixedly mounted on the support plate 12, a post sleeve 19 fixedly mounted on the outer side of the positioning post 18, and multiple sleeve ridges 20 evenly arranged on the outer side of the post sleeve 19. The sleeve ridges 20 and the post sleeve 19 are integrally formed and are made of wear-resistant rubber. The positioning clip effectively fixes the aluminum wheel and avoids damage to the aluminum wheel during fixing.

[0037] Furthermore, such as Figure 7As shown, the auxiliary flipping mechanism includes a rear support 21 fixedly mounted above and behind the workbench 1. A top plate 22 is fixedly mounted above the rear support 21. A wire groove 23 is formed below the top plate 22. A bidirectional threaded rod 24 is rotatably mounted in the wire groove 23. A set of drive blocks 26 are slidably connected in the wire groove 23. The two drive blocks 26 are threadedly connected to the two ends of the bidirectional threaded rod 24. A second motor 25 is mounted on one side of the top plate 22. The output end of the second motor 25 is connected to one end of the bidirectional threaded rod 24. A side support is fixedly mounted below the drive blocks 26. A rotating shaft 27 is mounted on the side support. An arc-shaped bracket 28 is fixedly mounted on the opposite surface of the rotating shaft 27. An arc-shaped pad 29 is fixedly installed on the inner side of the aluminum wheel, and a third motor 30 is installed at the outer end of the rotating shaft 27 on one side. Through the structure of the auxiliary flipping mechanism, in conjunction with the use of the lifting mechanism, it is easy to flip and polish the aluminum wheel, thereby improving the efficiency of polishing the aluminum wheel. The second motor 25 controls the rotation of the bidirectional threaded rod 24, so that the drive block 26 rotates synchronously in the groove 23. At this time, the two side supports move synchronously towards each other, so that the arc-shaped clamp 28 clamps the lifted aluminum wheel. The arc-shaped pad 29 is fixedly installed on the inner side of the arc-shaped clamp 28 to improve the positioning effect of the aluminum wheel. Through the operation of the third motor 30, the aluminum wheel between the two arc-shaped clamps 28 is flipped.

[0038] Furthermore, such as Figure 1 As shown, the dust handling mechanism has a cavity 31 on the polishing support 8. A dust collection groove 32 is detachably installed in the cavity 31. An air pipe 33 is installed on the front side of the dust collection groove 32. A negative pump 34 is fixedly installed above the worktable 1. The negative pump 34 is connected to the other end of the air pipe 33. Side perforated plates 35 are embedded on both sides of the upper part of the polishing support 8. A central perforated plate 36 is embedded in the middle of the polishing support 8. The holes of the side perforated plates 35 and the central perforated plate 36 are connected to the cavity 31. The dust collection mechanism is designed to prevent dust from scattering in the grinding area and affecting the working environment during wheel grinding. It is installed in the cavity 31 and the negative pump 34 is controlled to create negative pressure in the cavity 31. The scattered dust is sucked into the dust collection trough 32 through the holes on the central perforated plate 36 and the side perforated plates 35 on both sides. The air pipe 33 connected to the dust collection trough 32 is equipped with a screen at the end to block the dust in the dust collection trough 32.

[0039] Furthermore, such as Figure 8 As shown, the inner wall of the chip collection groove 32 is detachably provided with an electrostatic adsorption layer 37, which effectively adsorbs the dust in the cavity 31 into the chip collection groove 32.

[0040] Furthermore, such as Figure 1As shown, a sealing gasket 38 is fixedly provided on the inner front side of the cavity 31. The sealing gasket 38 fits against the front edge of the chip collection groove 32, improving the sealing between the chip collection groove 32 and the inner front side of the cavity 31.

[0041] Furthermore, such as Figure 1 As shown, a dustproof partition 39 is detachably installed above the polishing support 8. The horizontal cross section of the dustproof partition 39 is rectangular to block the dust splashed during the polishing of aluminum wheels.

[0042] Furthermore, such as Figure 6 As shown, the polishing mechanism includes an electric slide 40 fixedly mounted above the front side of the worktable 1. An electric slide block 41 is slidably connected to the electric slide 40. A vertical frame 42 is fixedly mounted above the electric slide block 41. A vertical groove 43 is provided on the vertical frame 42. A lead screw 44 is rotatably mounted in the vertical groove 43. A fourth motor 45 is mounted above the vertical frame 42. The output end of the fourth motor 45 is connected to the upper end of the lead screw 44. A horizontal frame 46 is slidably connected in the vertical groove 43. An electric rail frame 47 is embedded above the horizontal frame 46. An electric drive base 48 is slidably connected to the electric rail frame 47. A fixed part is mounted on the electric drive base 48. There is a support arm 49, on which a fifth motor 50 is fixedly installed. The output end of the fifth motor 50 is detachably equipped with a polishing disc 51. Through the structure of the polishing mechanism, the aluminum wheel is polished. The electric slide 41 moves on the electric slide table 40, thereby moving the polishing disc 51 horizontally. The operation of the fourth motor 45 causes the horizontal frame 46 to slide on the vertical frame 42, so that the polishing disc 51 moves vertically. The electric drive seat 48 slides on the electric rail frame 47, thereby moving the polishing disc 51 back and forth. The operation of the fifth motor 50 causes the polishing disc 51 to polish the aluminum wheel.

[0043] During operation, the wheel adjustment and positioning mechanism is designed with two synchronous electric push rods 17. By controlling the operation of the electric push rods 17, the right support plate 12 is pushed. At the same time, the slide 11 below the right support plate 12 slides on the slide rail 10, and the corresponding hinge 15 on it rotates the central rotating plate 14 on the central support platform 13. At this time, the hinge 15 on the other side pushes the left support plate 12 on the slide rail 10, thereby driving the wheel adjustment and positioning mechanism. This allows the four positioning clips to be positioned synchronously on the aluminum wheel. When polishing the inner wall of the wheel, the four positioning clips are driven to position the outer wall of the wheel. When polishing the outer wall of the wheel, the four positioning clips are driven to position the inner wall of the wheel. This improves the flexibility and practicality of the wheel adjustment and positioning mechanism.

[0044] By using the auxiliary flipping mechanism and the lifting mechanism, the aluminum wheels can be flipped and polished, improving the efficiency of polishing. The first motor 3 drives the threaded rod 4 to rotate. At this time, the pusher 5 slides on the side support on both sides, so that the pusher 5 moves up and down on the threaded rod 4, thereby pushing the polishing support 8. The second motor 25 controls the bidirectional threaded rod 24 to rotate, so that the drive block 26 rotates synchronously in the groove 23. At this time, the two side supports move synchronously towards each other, so that the arc-shaped clamp 28 clamps the lifted aluminum wheel. The arc-shaped pad 29 is fixedly set on the inner side of the arc-shaped clamp 28 to improve the positioning effect of the aluminum wheel. The third motor 30 flips the aluminum wheel between the two arc-shaped clamps 28.

[0045] By designing the dust handling mechanism, dust generated during wheel polishing is prevented from scattering in the polishing area and affecting the working environment. By controlling the operation of the negative pump 34, negative pressure is generated in the cavity 31. The scattered dust is sucked into the dust collection groove 32 through the holes in the central perforated plate 36 and the side perforated plates 35 on both sides. A screen is installed at the end of the air pipe 33 connected to the dust collection groove 32 to block the dust in the dust collection groove 32. Furthermore, an electrostatic adsorption layer 37 is detachably installed on the inner wall of the dust collection groove 32 to effectively adsorb the dust in the cavity 31 into the dust collection groove 32. A dustproof partition 39 is detachably installed above the polishing support 8. The cross-section of the dustproof partition 39 is rectangular to block the dust splashed during aluminum wheel polishing.

[0046] The polishing mechanism polishes the aluminum wheels. The electric slide 41 moves on the electric slide table 40, which in turn moves the polishing disc 51 horizontally. The operation of the fourth motor 45 causes the horizontal frame 46 to slide on the vertical frame 42, which in turn moves the polishing disc 51 vertically. The electric drive seat 48 slides on the electric rail frame 47, which in turn moves the polishing disc 51 back and forth. The operation of the fifth motor 50 causes the polishing disc 51 to polish the aluminum wheels.
