Abstract

The invention discloses a piezoelectric driving rotary table based on a spiral hinge mode conversion principle, which aims to solve the technical problems of complex structural design, low motion resolution and the like of a current micro-nano rotary table. The piezoelectric driving rotary table is composed of a rotary table, a shaft ring, a supporting cylinder, a spiral hinge base, a piezoelectric stack, a supporting cylinder connecting bolt, a driving lever mounting bolt, a driving lever and a pre-tightening screw. The deformation characteristic of the spiral hinge is utilized to convert thelinear motion of the piezoelectric stack into the rotary motion of the rotary table, so that the structural design complexity of the rotary platform is reduced, and the motion resolution of the rotary table is improved; meanwhile, the radial output force of the rotary table is increased through the lever transmission mechanism, and the output efficiency of the rotary table is improved; and the rotary table is connected with the supporting cylinder through the shaft ring, so that the load capacity of the rotary table is increased. The piezoelectric driving rotary table has the advantages of being simple in structure, high in positioning precision, large in load capacity and the like, and has good development potential and application value in the field of precision driving and positioning.
