The driving device of the equipment includes a first motor 13, a belt 14, a first gearbox 3 and a first transmission roller 4. The first motor 13 provides power, and transmits the power to the first gearbox 3 through the belt 14, and then drives the rotating plate 19 to rotate through the first transmission roller 4. The upper surface of the rotating plate 19 is provided with a plurality of clamping holes 20 for fixing the workpiece so that it can rotate smoothly during the processing to achieve the grinding action. The grinding head 18 is the core processing component, which is connected to the second gearbox 33 through the fixed shaft 21 and is powered by the second motor 31 for rotation. During the rotation process, the grinding head 18 performs precision grinding on the concave ball head. The pressure sensor 22 is distributed in a ring array on the surface of the fixed shaft 21 to monitor in real time whether there is uneven force during the grinding process. If uneven force is detected, the sensor will feedback a signal, and the system can adjust the grinding process in time to ensure the stability and accuracy of the processing process. During the grinding process, a large amount of heat will be generated between the grinding head 18 and the workpiece, which may affect The cooling liquid affects the machining accuracy. To solve this problem, the present invention designs a coolant circulation system. The coolant flows back to the filter box 9 through the reflux baffle 6 and the reflux pipe 7. After being filtered through the filter hole 10, the coolant is extracted by the pump body 12 and transported to the coolant collection box 15 through the inflow pipe 11. The coolant collection box 15 sprays the coolant to the grinding area through the spray hole 16 to cool the grinding head 18 and the workpiece to prevent high temperature from affecting the machining accuracy. The design of the grinding head 18 combines the micropores 23, the guide grooves 24 and the annular grooves 25. The guide grooves 24 and the annular grooves 25 are distributed in a circular array. These structures can effectively guide the flow of coolant and enhance the heat dissipation effect. This heat dissipation design can not only reduce the temperature of the grinding head 18 and prevent overheating, but also reduce the wear of the grinding head 18 and extend its service life. The design of the micropores 23 helps to further reduce the heat accumulation during grinding and ensure the continuous stability of the processing. The CNC grinder is equipped with an electric telescopic rod 27, which is connected to the upper support frame 28. The electric telescopic rod 27 can automatically adjust the height of the grinding head 18 according to processing needs, thereby adapting to workpieces of different specifications and improving the flexibility and accuracy of processing.
