Automatic coarse grinding and fine grinding integrated device for high-precision optical lens

The invention relates to the technical field of optical lenses, and discloses a high-precision optical lens automatic coarse grinding and fine grinding integrated device which comprises a grinding body. An optical lens is placed on a placing disc, then a second electric telescopic rod is driven to drive a clamping plate to clamp the optical lens, then a third electric telescopic rod is driven to drive a coarse grinding device to descend so that the placing disc can descend to the optical lens grinding position, and meanwhile a water pump is driven to extract cleaning liquid in a cleaning box; a telescopic pipe enters a spraying head to spray and clean the surface of the optical lens, the optical lens rotates through a first motor, a fine grinding device grinds the optical lens, it is guaranteed that the upper face and the lower face of the optical lens are ground through the first motor, and impurities generated during grinding fall into a waste box through a fine filter screen; and the waste box is drawn to
