Large-stroke two-freedom-degree gentle and precise positioning platform capable of realizing movement decoupling

The invention discloses a large-stroke two-freedom-degree gentle and precise positioning platform capable of realizing movement decoupling. The positioning platform comprises a fixed platform body, amovable platform body and a plurality of piezoelectric ceramic drivers, wherein the movable platform body is connected with the fixed platform body through a plurality of horizontal movement mechanisms, the piezoelectric ceramic drivers correspond to the horizontal movement mechanisms and exert external force on the horizontal movement mechanisms to make the horizontal movement mechanisms move, and the movement distance of the horizontal movement mechanisms is larger than the stretching or drawing distance of the piezoelectric ceramic drivers. By means of a hinge replacing method, the novel gentle mechanism and the gentle and precise positioning platform are designed, the two-freedom-degree movement in the plane is realized, and the movement decoupling and large-stroke movement can be realized. 本发明公开了一种可实现运动解耦的大行程
