[0034] Specifically, the interior of the cooling box 6 is filled with coolant; the heat sink 7 is annularly fixedly connected to the top wall of the cooling box 6;

[0035] Furthermore, when the nickel-chromium alloy beating grinding disc is rotating and grinding, the pure copper heat conductive sheet 3 transfers the heat generated by the grinding disc, and the heat is cooled and absorbed by the coolant in the cooling box 6, while the heat sink 7 on the top of the cooling box 6 dissipates the heat, thereby reducing the temperature of the grinding disc surface and the influence of the motor thermal stress on the grinding disc, thereby extending the service life; the heat sink 7 is designed in a ring shape on the top of the cooling box 6, so that the heat sink 7 can be in contact with the cooling box 6, thereby improving the heat dissipation efficiency.

[0036] See also Figure 2 , Figure 4 and Figure 5 The inner wall of the first mounting groove 4 is provided with a second mounting groove 9, and the bottom of the outer wall of the connecting column 5 is fixedly connected with a clamping plate 10, and the clamping plate 10 is engaged with the second mounting groove 9;

[0037] Specifically, the top of the connecting column 5 is fixedly connected with a telescopic rod 8; the top wall of the disk body 1 is evenly provided with a plurality of heat dissipation holes 11; the outer wall of the disk body 1 is evenly provided with a plurality of heat conduction grooves 12; the cooling box 6 and the heat sink 7 are both made of alloy material.

[0038] Furthermore, the connecting column 5 is engaged in the second mounting groove 9 opened inside the disc body 1 through the clamping plate 10, thereby further fixing the connecting column 5 to the grinding disc, improving the stability of the device and ensuring the safety of the grinding disc during operation; by installing the telescopic rod 8 on the top of the connecting column 5, the grinding gap of the grinding disc can be controlled, thereby improving the practicality of the device; by opening the heat dissipation holes 11 and the heat conduction grooves 12 on the surface of the disc body 1, the contact area between the grinding disc and the air can be increased, thereby improving the heat dissipation effect; the cooling box 6 and the heat sink 7 are made of alloy so that both are not affected by high temperature, thereby ensuring normal heat dissipation.

In order to save resources and reduce equipment costs, the places where the pure copper heat conducting sheets 3 are not in contact with the cooling box 6 can be designed as curved surfaces. The pure copper heat conducting sheets 3 can conduct the heat generated during the rotation of the grinding disc, and the heat is transmitted to the cooling box 6 through the pure copper heat conducting sheets 3. The coolant in the cooling box 6 absorbs the heat, and cooperates with the heat sink 7 on the top of the cooling box 6 to dissipate the heat, thereby reducing the surface temperature of the nickel-chromium alloy pulping grinding disc, reducing the influence of thermal stress on the grinding disc, and extending the service life of the grinding disc. At the same time, heat dissipation holes 11 and heat conducting grooves 12 are respectively opened on the top wall and outer wall of the disk body 1, which can increase the contact area between the grinding disc and the air, and further reduce the surface temperature of the disk body 1. At the same time, the connecting column 5 is engaged with the second mounting groove 9 through the clamping plate 10, thereby further improving the stability of the device, preventing the grinding disc from falling off during rotation, and ensuring the safety of the device.
