Automatic pressure device for grinding equipment

The invention provides an automatic pressure device for grinding equipment. The automatic pressure device for the grinding equipment comprises upper springs, wherein the lower ends of the upper springs are installed on the upper portion of a base disc of the grinding equipment, the upper ends of the upper springs are installed on the lower portion of an upper spring bearer plate, and the upper spring bearer plate is connected with an upper lifting driving mechanism which is used for driving the upper spring bearer plate to move up and down. The automatic pressure device further comprises lower springs, wherein the upper ends of the lower springs are installed on the lower portion of the base disc, the lower ends of the lower springs are installed on a lower spring bearer plate, the lower spring bearer plate is connected with a lower lifting driving mechanism which is used for driving the lower spring bearer plate to move up and down, and the upper spring bearer plate, the base disc and the lower spring bearer plate are coaxial with one another. The automatic pressure device for the grinding equipment is capable of applying a load larger than the dead weight of grinding discs and a load smaller than the dead weight of the grinding discs at the same time, high in control accuracy, good in stability and low in cost.
