[0002] The wheel hub is one of the important components of a car. It is an important connecting component between the tire and the braking system, and plays a role in transmitting power. Since burrs will appear on the outer surface of the wheel hub during the production process, the burrs need to be polished to improve the practicality and aesthetics of the wheel hub.

[0003] When the wheel hub outer surface burr polishing device is in use, the operator needs to place the wheel hub on a special tray, then turn on the device to place the grinding rod on the wheel hub surface, and start polishing with the grinding rod. After polishing is completed, the wheel hub is taken out of the tray, and a new wheel hub is placed in the tray to continue the next polishing process, and so on.

[0030] Further, the electric push rod 201 is started to drive the first rack 202 to move. Since the first rack 202 and the second rack 204 are both meshed with the gear 203, when the first rack 202 moves, it will drive the gear 203 to rotate. When the gear 203 rotates, it will drive the second rack 204 to move in the opposite direction. When the first rack 202 and the second rack 204 move, they will drive the connecting block 205 to move. When the connecting block 205 moves, it will drive the slider 207 to slide on the surface of the slide rod 206, so as to support the connecting block 205, and further enable the slider 207 to drive the arc clamping plate 208 to fix and clamp the wheel hub, so as to avoid the wheel hub from vibrating due to the excessive rotation speed of the polishing rod 402, causing the wheel hub to deviate, affecting the polishing effect of the wheel hub, thereby preventing the wheel hub from vibrating or deviating during the polishing process and preventing the wheel hub from being damaged.

[0031] Example 2

[0032] Reference Figure 1 , Figure 2 and Figure 6 , which is the second embodiment of the utility model, is based on the previous embodiment, and a cleaning component 3 is provided on the upper surface of the workbench 1.

[0033] Specifically, the cleaning component 3 includes a driving box 301 fixedly mounted on the upper surface of the workbench 1, the interior of the driving box 301 is connected to a rotating rod 302 through a bearing seat, the inner wall of the driving box 301 is fixedly connected to a driving motor 303, the output shaft end of the driving motor 303 is fixedly connected to a worm 304, the outer surface of the rotating rod 302 is fixedly connected to a worm wheel 305, the worm 304 and the worm wheel 305 are meshed, the rotating rod 302 is inserted into the outer surface of the driving box 301 and is fixedly connected to an electromagnet 306, the lower surface of the workbench 1 is fixedly connected to a connecting plate, the upper surface of the connecting plate is fixedly connected to a bidirectional motor 4, the output shaft end of the bidirectional motor 4 is fixedly connected to a tray 401, the outer surface of the bidirectional motor 4 is connected to an operating controller, and the length of the electromagnet 306 is equal to the sum of the diameter of the tray 401 and the distance from the axis of the rotating rod 302 to the edge of the tray 401.

[0034] Further, the drive motor 303 is started to drive the worm 304 to rotate. Because the worm 304 and the worm wheel 305 are meshed, when the worm 304 rotates, the worm wheel 305 is driven to rotate. When the worm wheel 305 rotates, the rotating rod 302 is driven to rotate. When the rotating rod 302 rotates, the electromagnet 306 is driven to rotate. When the electromagnet 306 swings to the edge of the tray 401, the electromagnet 306 is energized. When the electromagnet 306 swings onto the tray 401, the iron filings generated by polishing can adhere to the surface of the electromagnet 306, and the electromagnet 306 is swung to the surface of the installation box 101. The drive motor 303 is started again to drive the rotating rod 302 to rotate in the opposite direction, so that the rotating rod 302 drives the electromagnet 306 to restore the initial position, and then the electromagnet 306 is powered off, so that the iron filings adhered to the lower surface of the electromagnet 306 fall into the recycling box for storage, so as to quickly clean the iron filings on the surface of the tray 401.

[0035] Working principle: When in use, the device is placed in the specified position through the support rod 403 on the lower surface of the workbench 1, so that the support rod 403 supports the device as a whole. At this time, the wheel hub that needs to be burred and polished is placed on the tray 401, and then the electric push rod 201 is started to drive the first rack 202 to move. Because the first rack 202 and the second rack 204 are both engaged with the gear 203, when the first rack 202 moves, it will drive the gear 203 to rotate, and when the gear 203 rotates, it will drive the second rack 204 to move in the opposite direction. When the first rack 202 and the second rack 204 move, they will drive the sliding block 210 to slide in the slide rail 209, so as to support the first rack 202 and the second rack 204. Further, when the first rack 202 and the second rack 204 move, they will drive the connecting block 205 to move, and when the connecting block 205 moves, it will drive The slider 207 slides on the surface of the slide rod 206 to support the connecting block 205, and further enables the slider 207 to drive the arc clamping plate 208 to fix and clamp the wheel hub, so as to prevent the wheel hub from vibrating due to the excessive rotation speed of the polishing rod 402, causing the wheel hub to deviate and affecting the polishing effect of the wheel hub, thereby preventing the wheel hub from vibrating or deviating during the polishing process and preventing the wheel hub from being damaged, thereby starting the polishing rod 402 and the polishing frame to polish the burrs on the outer surface of the wheel hub. At the same time, by operating the controller, the controller drives the bidirectional motor 4 to perform intermittent movement, and further enables the bidirectional motor 4 to drive the tray 401 to rotate, so that the tray 401 drives the wheel hub to move. When the wheel hub needs to rotate, the groove inside the arc clamping plate 208 and the roller 211 cooperate with each other to drive it to move, so that the wheel hub can be polished, so that the polishing of the wheel hub is more uniform, and its polishing quality is effectively improved.

[0036] When polishing is completed, the staff can start the drive motor 303 to drive the worm 304 to rotate. Because the worm 304 and the worm wheel 305 are meshed, when the worm 304 rotates, the worm wheel 305 is driven to rotate. When the worm wheel 305 rotates, it drives the rotating rod 302 to rotate. When the rotating rod 302 rotates, it drives the electromagnet 306 to rotate. When the electromagnet 306 swings to the edge of the tray 401, the electromagnet 306 is energized. When the electromagnet 306 swings to the tray 401, the iron chips generated by polishing can be removed. The iron filings adhere to the surface of the electromagnet 306, so that the electromagnet 306 swings to the surface of the installation box 101, and then the driving motor 303 is started to drive the rotating rod 302 to rotate in the opposite direction, so that the rotating rod 302 drives the electromagnet 306 to restore the initial position, and then the electromagnet 306 is powered off, so that the iron filings adhered to the lower surface of the electromagnet 306 fall into the recycling box for storage, so as to quickly clean the iron filings on the surface of the tray 401, avoid the accumulation of foreign matter such as iron filings on the surface of the tray 401, affect the stability of the later polishing of the wheel hub, and reduce air pollution.
