The cooling water inside the separation box 101 is transferred to the cooling water pump 103 through the water inlet pipe 102, and the cooling water in the cooling water pump 103 is transferred to the water storage cylinder 11 through the water outlet pipe 106, so as to solve the problem that the common oil distribution plate grinding device only includes the oil distribution plate grinding device, which can perform the work of grinding the oil distribution plate, but lacks the recycling of cooling water. Long-term grinding work will increase the surface temperature of the oil distribution plate, thereby affecting the grinding accuracy, and a large amount of cooling water is required for cooling.

[0026] See also Figure 1-Figure 5In this embodiment, an electric telescopic rod 12 is welded to the position of the placement slot 3 at the bottom end of the water storage cylinder 11, and a frame 14 is welded to the bottom end of the electric telescopic rod 12. A motor 7 is provided at the bottom center position inside the frame 14, and a grinding disc 8 is provided below the frame 14. The output end of the motor 7 passes through the frame 14 and is connected to the grinding disc 8.

Pads 104 are welded at the four feet of the bottom of the grinding box 1 to reduce the direct friction between the grinding box 1 and the ground, increase the stability of the grinding box 1, and prevent the grinding box 1 from being damaged due to direct friction between the bottom of the grinding box 1 and the ground, thereby affecting the grinding accuracy. A slot 105 is provided at the center of the side of the polishing box 1. The handle of the filter 5 passes through the slot 105 to the outside of the polishing box 1.

When the output end of the motor 7 inside the frame 14 drives the grinding plate 8 to grind, the cooling water in the water storage cylinder 11 is sprayed to the surface of the oil distribution plate through the universal joint nozzle 6 to cool down the temperature. When the cooling water overflows to the second water flow hole 13, the cooling water flows into the filter screen 5 through the second water flow hole 13. The filter screen 5 absorbs impurities such as dust and flows into the separation box 101.
