[0045] In this embodiment, a top groove 32 and a bottom groove 33 are respectively provided at the upper and lower ends of the processing table 3, so as to facilitate the sliding connection of the movable plate 61 in the top groove 32 and the bottom groove 33, wherein a through hole 611 is provided on the movable plate 61, so as to facilitate the output end of the driving motor 621 to pass through the through hole 611, and is connected to a driving gear 622, the outer periphery of the driving gear 622 is meshed with the tooth groove 31 of the processing table 3, when the driving motor 621 drives the driving gear 622 to operate, it drives the movable plate 61 to rotate circumferentially on the processing table 3 by cooperating with the tooth groove 31, so that the first grinding part 81 and the second grinding part 82 thereof are rotated, so as to facilitate the circumferential grinding of the outer wall of the wheel belt.

[0046] In one embodiment, see Figure 1 - Figure 8 In order to improve the grinding efficiency of the whole device and avoid the situation that the grinding end is overheated and needs to stop, there are two telescopic mechanisms 7, wherein any telescopic mechanism 7 includes a cylinder 71 and a mounting frame 72, and the telescopic ends of the two cylinders 71 are connected to the mounting frame 72, and the two mounting frames 72 are respectively connected with the first grinding part 81 and the second grinding part 82, and the first grinding part 81 and the second grinding part 82 include a temperature sensor 83, a motor 84 and a grinding roller 85; the temperature sensor 83 is installed in the mounting frame 72, and a motor 84 is arranged on the top of the mounting frame 72, and the output end of the motor 84 extends into the mounting frame 72 and is connected to the grinding roller 85, and the cooling mechanism 9 includes a water tank 91 and a spray mechanism 92, The water tank 91 is arranged on the movable plate 61, and the spray mechanism 92 includes a guide pipe 921 and a water pump 922; one end of the guide pipe 921 is connected to the water tank 91, and the end of the guide pipe 921 extends into the installation frame 72, and is used to spray and cool the grinding roller 85, the guide pipe 921 is connected to the water pump 922, and the movable plate 61 is provided with a dust collection mechanism 10, which includes a dust box 101, a dust collection pipe 102 and a dust collection pump 103; the number of dust boxes 101 is two, and the two dust boxes 101 are arranged on both sides of the movable plate 61, one end of the dust box 101 is connected to the dust collection pipe 102, the other end of the dust collection pipe 102 extends into the installation frame 72, and the dust collection pipe 102 is installed with a dust collection pump 103.

[0047] In this embodiment, two cylinders 71 are provided, and each cylinder 71 is connected to a mounting frame 72, wherein the first grinding part 81 and the second grinding part 82 are respectively mounted on the two mounting frames 72, and the staff can select the grinding mode, and when the first grinding part 81 is running, the second grinding part 82 is stopped. When the temperature sensor 83 detects that the temperature of the first grinding part 81 is high, the telescopic end of the cylinder 71 begins to retract, so that the first grinding part 81 retracts to the movable plate 61. And through the cooperation of the water pump 922 and the guide pipe 921, the coolant in the water tank 91 is extracted and sprayed on the surface of the grinding roller 85 to cool it down. While cooling down, the second grinding part 82 extends outward to grind the surface of the wheel belt. This can avoid the grinding gap caused by high temperature and ensure the grinding efficiency of the grinding device. The dust generated during the grinding process is sucked into the dust collecting box 101 through the cooperation of the dust suction pump 103 and the dust suction pipe 102, thereby avoiding the situation where dust floats in the working environment.

[0048] In one embodiment, in order to facilitate the staff to operate the device,

[0049] S1, start the fastening mechanism 5, fix the wheel rim to be polished at the center of the processing table 3, and prepare for repair and polishing;

[0050] S2. After the wheel band is tightened, the movable mechanism 6 is started, and the movable mechanism 6 and the tooth groove 31 are cooperated to make it move circumferentially on the periphery of the processing table 3, and the telescopic mechanism 7 is started to control the first grinding part 81 or the second grinding part 82 to grind the surface of the wheel band. During the grinding process, the movable plate 61 can move circumferentially to evenly grind the periphery of the wheel band.

[0051] S3. When the surface temperature of the first grinding part 81 is too high during the grinding process, it is retracted onto the movable mechanism 6, and the second grinding part 82 is pushed to grind the surface of the wheel band, and the surface of the first grinding part 81 is cooled by the cooling mechanism 9, so as to facilitate subsequent processing.

[0052] In order to better understand the present invention, the following Figures 1 to 8The technical solution of the present invention is described in detail: the staff places the wheel to be polished at the center of the processing table 3, and starts the four electric rods, pushes the protection pad 53 through the electric telescopic rod 52, and presses the inner wall of the wheel, and then starts the drive motor 621. The drive motor 621 drives the drive gear 622 to operate and cooperates with the tooth groove 31 to make the movable plate 61 rotate on the processing table 3, wherein two polishing parts are set, the first polishing part 81 and the second polishing part 82. Under normal circumstances, the staff can choose one of the polishing parts for polishing. When the cylinder 71 pushes the mounting frame 72 and drives the first polishing part 81 to polish the outer wall of the wheel, the second polishing part 82 is located on the movable plate 61. The temperature sensor 83 is provided on the two mounting frames 72 to monitor the temperature of the polishing roller 85. When the temperature of the first polishing part 81 is too high, the cylinder 71 retracts and drives the first polishing part 81 to polish the outer wall of the wheel. 1 retracts to the movable plate 61, and controls the second grinding part 82 to continue grinding the surface of the wheel belt, and starts the water pump 922. Through the cooperation of the water pump 922 and the guide pipe 921, the coolant in the water tank 91 is extracted, and the surface of the first grinding part 81 is sprayed to cool down. When the temperature sensor 83 detects that the temperature of the second grinding part 82 is too high, the cylinder 71 drives the second grinding part 82 to retract to the movable plate 61. At this time, the first grinding part 81 grinds the outer wall of the wheel belt, and the spray mechanism 92 sprays the second grinding part 82. In the grinding process, the dust generated by the grinding is adsorbed by the dust suction mechanism 10 to avoid excessive dust. By arranging the mounting frame 11 and the camera 12 on the bottom plate 1, it is convenient for the staff to remotely monitor and check the grinding condition of the wheel belt. When it is necessary to speed up the grinding efficiency, the first grinding part 81 and the second grinding part 82 can be started at the same time to improve the grinding efficiency of the entire device.

[0053] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention.
