Abstract

The invention provides a large load-bearing piezoelectric stick-slip rotating table using an asymmetric conversion hinge, and aims to solve the problems of complex hinge structure, small rotation range, weak bearing capacity and the like of the existing piezoelectric stick-slip rotating table. The large load-bearing piezoelectric stick-slip rotating table comprises a rotating table, a bearing, a supporting cylinder, a cylinder fixing bolt, a driving assembly fixing bolt, a driving assembly and a bottom table. The inner ring of the bearing is in interference-fit with the rotating table. The outer ring of the bearing is in interference-fit with the supporting cylinder. The driving assembly is fixedly installed on the bottom table through the driving assembly fixing bolt. The driving assemblyis in contact with the lower end of the rotating table. The supporting cylinder is fixedly installed on the bottom table through the cylinder fixing bolt. The used asymmetric conversion hinge has a central symmetric structure, and the asymmetric conversion hinge generates contraction oblique displacement to clamp the rotating table and generates torque to enable the rotating table to rotate due to uneven distribution of the hinge rigidity. The large load-bearing piezoelectric stick-slip rotating table has the characteristics of simple structure, large rotation range, high bearing capacity, high positioning accuracy and the like and has wide application prospects in the field of micro-nano precision driving and positioning.
