[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example

[0033] like Figure 1-Figure 5 As shown, an automobile wheel hub polishing device disclosed in the present invention includes a bottom plate 1, a base 23 arranged on the upper surface of the bottom plate 1, and a material barrel 9 arranged above the base 23. The material barrels 9 used in the present technical solution are all cylindrical components with a bottom seal. A plurality of vibration motors are evenly arranged on the bottom surface of the material barrel 9 along the circumferential direction. The vibration motor can drive the material barrel 9 to vibrate during operation, so that the polishing abrasive inside the material barrel 9 polishes the surface of the automobile wheel hub.

[0034] A plurality of height-adjusting telescopic rods 16 are evenly and vertically arranged on the outer side of the barrel 9 along the horizontal circumferential direction. The plurality of height-adjusting telescopic rods 16 can be extended and retracted in sequence along the same direction to adjust the inclination angle of the barrel 9. In this embodiment, each height-adjusting telescopic rod 16 can be extended and retracted in sequence in a clockwise or counterclockwise direction on the base 23. The polishing material in the barrel 9 slides around a ring under the action of gravity, and in this process, the surface of the automobile wheel hub is shear-polished.

[0035] Each height-adjustable telescopic rod 16 is adjusted in distance from the material barrel 9 through a spacing-adjusting assembly arranged in the base 23. A buffering and shock-absorbing assembly is provided at the top end of the height-adjustable telescopic rod 16. The function of the buffering and shock-absorbing assembly is to reduce the impact force on the height-adjustable telescopic rod 16 during the vibration of the material barrel 9, and to avoid deformation of the structure of the height-adjustable telescopic rod 16 resulting in insensitive movement. A connecting assembly is provided at the top end of the buffering and shock-absorbing assembly, and the buffering and shock-absorbing assembly is fixedly connected to the material barrel 9 through the connecting assembly.

[0036] A support column 2 is fixedly provided on the upper surface of the bottom plate 1 on one side of the base 23, and a height-adjustable height-adjusting slider 4 is slidably provided in the support column 2. An extension arm 5 is horizontally connected to the side wall of the height-adjusting slider 4, and two connecting arms 6 are provided at the bottom end of the extension arm 5. A hub clamping ring 17 is provided on the inner side of the two connecting arms 6. Connecting rods 18 that penetrate the connecting arms 6 and the hub clamping ring 17 are provided at both ends of the hub clamping ring 17 facing the connecting arms 6. The connecting rod 18 is driven to rotate and adjust the deflection angle of the hub clamping ring 17 by the driving assembly. In the present embodiment, it is easier for the hub clamping ring 17 to flip over inside the barrel 9 and adjust the direction of the automobile wheel hub inside it, so that the automobile wheel hub can be better polished inside the barrel 9.

[0037] A plurality of clamping assemblies are horizontally arranged on the inner side of the hub clamping ring 17 along the circumferential direction. The automobile hub is arranged at the center of the same plane of the hub clamping ring 17 and is fixed by the clamping assemblies.

[0038] Specifically, the spacing adjustment component includes an adjusting screw 25, an adjusting slider 26 and a bevel gear 27. A driving motor is embedded at the central axis of the base 23, and a bevel gear is sleeved on the output shaft of the driving motor. Guide grooves 24 with the same number as the height adjustment telescopic rod 16 are uniformly opened horizontally along the circumferential direction on the base 23. Each adjusting screw 25 is arranged inside the guide groove 24 along the groove direction of the guide groove 24, and the end of the adjusting screw 25 facing the central axis of the base 23 extends to the bevel gear. Several bevel gears 27 are respectively sleeved on the ends of the adjusting screws 25 and mesh with the bevel gears to drive several adjusting screws 25 to rotate along their axes. In this embodiment, the angular velocity of each adjusting screw 25 during operation is kept consistent, so that the actions of each adjusting slider 26 are kept consistent.

[0039] The outer wall of each adjusting screw 25 is threadedly sleeved with an adjusting slider 26, and the bottom end of the height-adjusting telescopic rod 16 is fixed to the upper surface of the adjusting slider 26. The adjusting slider 26 is displaced along the guide groove 24 inside the guide groove 24 and adjusts the distance between the height-adjusting telescopic rod 16 and the barrel 9. In this embodiment, when the distance between each height-adjusting telescopic rod 16 is increased or decreased, barrels 9 of different specifications can be placed inside thereof to facilitate polishing of automobile wheels of different sizes.

[0040] Specifically, the buffer shock-absorbing assembly includes a first connecting plate 12, a shock-absorbing spring 13, a buffer ball 14 and a second connecting plate 15. The buffer ball 14 is arranged above the height-adjusting telescopic rod 16, and the top and bottom ends of the buffer ball 14 are symmetrically connected with the shock-absorbing spring 13. The first connecting plate 12 and the second connecting plate 15 are respectively arranged above and below the buffer ball 14 and are both connected to the shock-absorbing spring 13. The shock-absorbing spring 13 can be deformed, stretched and compressed during the vibration of the barrel 9 to reduce the impact force on the height-adjusting telescopic rod 16. The bottom end of the second connecting plate 15 is connected to the output end of the height-adjusting telescopic rod 16, and the top of the first connecting plate 12 is connected to the connecting assembly.

[0041] Specifically, the connecting assembly includes a support arm 10, a buffer slider 22 and a connecting block 11. The support arms 10, which are the same in number as the height-adjusting telescopic rods 16, are evenly and horizontally fixed to the outer wall of the material barrel 9 along the circumferential direction of the material barrel 9. The bottom surface of each support arm 10 is provided with a slide groove 20 in the direction away from the material barrel 9. The buffer slider 22 is embedded in the slide groove 20 and slides along the direction of the slide groove 20. The buffer slider 22 in this embodiment is a T-shaped component with a wide top and a narrow bottom. The bottom end of the slide groove 20 extends inward and cooperates with the T-shaped structure, so that the buffer slider 22 is embedded in the slide groove 20 and slides stably, while preventing the buffer slider 22 from separating from the support arm 10.

[0042] A connecting block 11 is fixedly provided on the bottom surface of the buffer slider 22, and the connecting block 11 is rotatably connected to the first connecting plate 12 via a rotating shaft. In this embodiment, the rotating shaft allows the angle between the connecting block 11 and the first connecting plate 12 to be adjusted, thereby facilitating the height adjustment of the telescopic rod 16 to lift the material barrel 9.

[0043] Specifically, each slide groove 20 is provided with a pressure spring 21, and the two ends of the pressure spring 21 are respectively in contact with the side walls of the barrel 9 and the buffer slider 22. In this embodiment, the pressure spring 21 causes the buffer slider 22 to move toward the side away from the barrel 9, thereby allowing the barrel 9 to be located in the central area of ​​each height adjustment telescopic rod 16.

[0044] Specifically, the driving assembly includes an auxiliary adjusting motor 7 and a synchronous roller 8. The synchronous roller 8 is horizontally arranged above the hub clamping ring 17, and both ends of the synchronous roller 8 pass through the side wall of the connecting arm 6. The inner part of the hollow connecting arm 6 is located on the outer wall of the synchronous roller 8 and the connecting rod 18, and a driving gear is sleeved. The outer walls of the two driving gears located inside the connecting arm 6 are sleeved with an annular transmission belt 19. The auxiliary adjusting motor 7 is fixed to the bottom surface of the extension arm 5, and the output shaft of the auxiliary adjusting motor 7 is connected to the synchronous roller 8 and drives the synchronous roller 8 to rotate, so that the two connecting rods 18 rotate at the same angular velocity. In this embodiment, the synchronous roller 8 makes the two transmission belts 19 move in unison, thereby making the forces at both ends of the hub clamping ring 17 consistent during rotation.

[0045] Specifically, the clamping assembly includes a plurality of clamping telescopic rods 28 horizontally arranged on the inner wall of the wheel hub clamping ring 17, a U-shaped frame 29 is fixedly provided on the protruding end of the clamping telescopic rod 28, and a clamping roller 30 is provided inside the U-shaped frame 29 which is different from one end of the clamping telescopic rod 28 and is rotated by a rotating shaft. When the plurality of clamping telescopic rods 28 are pushed out of the protruding end, the automobile wheel hub is fixed by the clamping roller 30, and a servo motor 31 is fixedly provided on the U-shaped frame 29, and the output shaft of the servo motor 31 is connected to the rotating shaft, and drives the clamping roller 30 to drive the automobile wheel hub to rotate. In this embodiment, the rotating shaft passes through the axis of the clamping roller 30, and the two ends of the rotating shaft pass through the two ends of the U-shaped frame 29, and can rotate around the rotating shaft in the U-shaped frame 29, and the clamping roller 30 causes the automobile wheel hub inside thereof to rotate during the rotation process, so that the contact surface between the clamping roller 30 and the automobile wheel hub changes, which is convenient for the polishing material to perform a dead angle polishing process on the surface of the automobile wheel hub.

[0046] Specifically, an adjustment groove is vertically opened on the side wall of the support column 2 facing the barrel 9, a height adjustment screw is vertically arranged in the adjustment groove, a height adjustment slider 4 is threadedly sleeved on the height adjustment screw, a height adjustment motor 3 is fixedly arranged on the top of the support column 2, and the output shaft of the height adjustment motor 3 is connected to the height adjustment screw. In this embodiment, when the height adjustment motor 3 is in operation, it is convenient to adjust the height of the extension arm 5, so that the staff can place or remove the car wheel hub conveniently.

[0047] Specifically, the diameter of the shock-absorbing spring 13 gradually increases as it extends toward the end away from the buffer ball 14. In this embodiment, the shock-absorbing spring 13 is designed in a trumpet-shaped structure, which can further improve the stability of the shock-absorbing spring 13 when dealing with lateral vibration force, while avoiding irreversible deformation caused by excessive lateral force on the shock-absorbing spring 13, thereby improving the service life of the shock-absorbing spring 13 and the stability of the polishing equipment during the polishing process.

[0048] The working principle and use process of the present invention are as follows: During the use of the polishing equipment in the present invention, the staff first operates the height adjustment motor 3. During the operation of the height adjustment motor 3, the height adjustment screw on the output shaft is driven to rotate. During the rotation of the height adjustment screw, the height of the height adjustment slider 4 on the side wall of the support column 2 can be adjusted. During the height adjustment process of the height adjustment slider 4, the height of the extension arm 5 can be synchronously adjusted. During the height adjustment process of the extension arm 5, the position of the connecting arm 6 and the hub clamping ring 17 under the connecting arm 6 can be synchronously adjusted.

[0049] The staff first manually places the wheel hub horizontally on the inner side of the wheel hub clamping ring 17. At this time, the wheel hub clamping ring 17 is a hollow structure. Polishing abrasives are provided inside the material barrel 9 directly below the wheel hub clamping ring 17. When the automobile wheel hub is placed on the inner side of the wheel hub clamping ring 17, the polishing abrasives can lift the automobile wheel hub. Then the staff starts the clamping telescopic rod 28. The clamping telescopic rod 28 will extend during the power-on startup process and push out the protruding end, so that the clamping roller 30 clamps and fixes the wheel hub.

[0050] Polishing abrasives are arranged inside the barrel 9, and the polishing abrasives are in contact with the side walls of the wheel hub. A plurality of vibration motors are evenly fixed on the bottom surface of the barrel 9, and the polishing abrasives inside the barrel 9 are driven to vibrate when the vibration motor is running. The height adjustment motor 3 drives the lead screw on its output shaft to rotate when it is running in reverse, so that the height of the height adjustment slider 4 is lowered. When the height adjustment slider 4 and the extension arm 5 are lowered, the height of the wheel hub clamping ring 17 is adjusted, so that the automobile wheel hub inside the wheel hub clamping ring 17 sinks into the barrel 9. At this time, the polishing abrasive inside the barrel 9 completes the wrapping of the wheel hub clamping ring 17 and the automobile wheel hub, and the surface of the wheel hub is polished during the vibration of the polishing abrasive.

[0051] During the polishing process of the automobile wheel hub inside the hub clamping ring 17 by the polishing equipment, the bottom surface of the hub will be polished more ideally than the upper surface. The staff adjusts the height adjustment motor 3 to increase the height of the extension arm 5, thereby lifting the automobile wheel hub in the hub clamping ring 17 from the polishing abrasive.

[0052] The auxiliary adjustment motor 7 adjusts the rotation of the synchronous roller 8 during power-on. The synchronous roller 8 drives the transmission belt 19 during rotation. The transmission belt 19 drives the connecting rod 18 to rotate during transmission. The connecting rod 18 can synchronously adjust the rotation of the hub clamping ring 17 during rotation. The hub clamping ring 17 can adjust the angle of the internal hub during rotation.

[0053] When the servo motor 31 is powered on, it can drive the clamping roller 30 to rotate. The staff can adjust the rotation of the wheel hub through the rotating clamping roller 30 to prevent the connection area between the wheel hub and the clamping device from being unable to be polished.

[0054] During the polishing process of the automobile wheel hub by the polishing equipment, the multiple height-adjustable telescopic rods 16 at the outer edge of the barrel 9 can be extended and contracted in sequence in a clockwise or counterclockwise direction on the base 23, so that one end of the barrel 9 is locally raised or lowered, so that the polishing abrasive inside the barrel 9 can slide along the tangent of the hub surface, making it easier to polish the hub surface.

[0055] A shock absorbing spring 13 and a buffer ball 14 are provided at the top of the height-adjusting telescopic rod 16, which are convenient for shock absorbing the support arm 10. The buffer slider 22 is stuck in the inside of the slide groove 20 and can slide along the slide groove 20, so as to facilitate the partial raising or lowering of the bucket 9.

[0056] When the driving motor in the base 23 is running, it drives the bevel gear to rotate, and the bevel gear drives the circular bevel gear 27 to rotate. When the circular bevel gear 27 rotates, the adjusting screw 25 is adjusted to rotate. When the adjusting screw 25 rotates, the adjustment slider 26 is adjusted to move inside the guide groove 24, thereby adjusting the spacing between the height adjustment telescopic rods 16, so as to facilitate the setting of various barrels 9 of different specifications in the polishing equipment.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to be a further limitation of the present invention. All equivalent changes made using the contents of the present specification and drawings are within the protection scope of the present invention.
