Resistor disc grinding equipment capable of automatically feeding and discharging

The invention relates to the technical field of resistor disc grinding, and discloses automatic feeding and discharging resistor disc grinding equipment which comprises a supporting table, a grinding mechanism is fixedly connected to one side of the top end of the supporting table, a turnover mechanism is fixedly connected to the top end of the supporting table, and a clamping mechanism is fixedly connected to the side face of the turnover mechanism. A lightning arrester resistor disc is movably connected into the clamping mechanism, and a collecting mechanism is arranged below the clamping mechanism. The clamping mechanism is driven by the synchronous belt to integrally move, when the clamping mechanism is located below the grinding mechanism, one face of the lightning arrester resistor disc in the clamping mechanism can be ground at the moment, after one face of the lightning arrester resistor disc is ground, the servo motor rotates again, the clamping mechanism rotates by 180 degrees, and the lightning arr
