[0028] See also Figure 5 A coin-shaped steel plate grinding disc is shown, in which a water inlet pipe 302 is fixedly connected to the side of a micro water pump 301, and a cooling box 303 is fixedly connected to the bottom end of the water inlet pipe 302, and a circulating water pipe 304 is fixedly connected to the side of the cooling box 303; the micro water pump 301 forms a connecting structure with the cooling box 303 through the water inlet pipe 302, and the cooling box 303 forms a connecting structure with the micro water pump 301 through the circulating water pipe 304.

[0029] Working principle: First, assemble the device on the grinder, and then place the steel plate to be ground on the bottom of the device. When the grinder drives the device to rotate, the grinding rod fixed inside the support disk 101 starts to work to grind the steel plate. While grinding, turn on the micro water pump 301 on the top of the shell 201. The micro water pump 301 draws water or coolant from the cooling box 303 through the water inlet pipe 302 and circulates it through the circulating water pipe 304 for cooling. When the coolant or water flows in the circulating water pipe 304, the circulating water pipe 304 is in contact with the plate 203, and the plate 203 is in contact with the grinding rod, so that the heat generated by the grinding rod is transferred out. The material of the plate 203 is aluminum nitride, which is often used as a substitute for beryllium oxide. Unlike beryllium oxide, aluminum nitride does not cause health hazards to production, but still exhibits chemical and physical properties similar to beryllium oxide. Aluminum nitride is one of the few materials known to have electrical insulation and high thermal conductivity, and has excellent thermal shock resistance, thereby achieving a cooling effect. When the grinding rod needs to be replaced after a long time of use, first turn the rotating handle 206 to fix the plate 203. 5 is rotated to a state of vertical overlap with the clamping plate 204, and then the housing 201 is removed, the nut 106 is turned to loosen the threaded rod 107, and the threaded rod is rotated successively to remove the worn grinding rod. A rotating shaft is installed between the threaded rod 107 and the clamping plate 104 to facilitate the backward movement of the clamping plate 104, and a new grinding rod is placed in the middle of the clamping plate 104, and the thread is rotated to clamp the grinding rod. The thread is fixed by the rotating nut 106 to fix the threaded rod 107. When the installation is completed, the housing 201 is covered on the supporting plate 101, and the fixing plate 205 is rotated to fix the housing 201, and then the electric telescopic rod 202 drives the abutment plate 203 to descend to limit the grinding rod.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
