One-dimensional large-stroke precise positioning platform

A one-dimensional large-stroke precise positioning platform, comprising:

• a housing;
• a cross ball guiding rail arranged at one side of the housing, the cross ball guiding rail comprising a mover guiding rail and stator guiding rails oppositely arranged at two sides of the mover guiding rail;
• the stator guiding rails being parallel to the mover guiding rail, and the stator guiding rails being fixed on the housing
• a piezoelectric ceramic and an elastic member disposed within the housing;
• a containing chamber disposed within the housing for containing the piezoelectric ceramic and the elastic member, a first fixing member and a second fixing member being provided in the containing chamber, and the first fixing member and the second fixing member being movable in the containing chamber along the longitudinal direction of the mover guiding rail;
• wherein in the longitudinal direction of the mover guiding rail, one end of the piezoelectric ceramic is abutted against the first fixing member, and the other end of the piezoelectric ceramic is abutted against the second fixing member, the mover guiding rail being fixed on the second fixing member, and the elastic member being fixed on the first fixing member;
• in the width direction of the mover guiding rail, the two sides of the elastic member are abutted against the inner side surfaces of the containing chamber, and the first fixing member being connected with the second fixing member by a flexible member.
