Flexible control device for lifting of grinding head of grinding equipment

The invention discloses a flexible control device for lifting of a grinding head of grinding equipment. The flexible control device comprises a stander, a driving motor and a motor support, wherein the driving motor is positioned in the motor support; the motor support, through a sliding block, is connected with a sliding rail arranged on one side of the stander in a sliding manner; the lower end of a main shaft of the driving motor is connected with a grinding head assembly; a flexible grinding head lifting mechanism is arranged at the top of the motor support through a bracket; a limiting piece is arranged on the stander. The device can automatically realize flexible lifting of the grinding head according to real-time pressure between the grinding head and a lens, thus automatically realizing flexible lifting of the grinding head; therefore, the grinding head can keep proper pressure all the time; crushing of the lens can be prevented, and the grinding efficiency can be improved.
