Abstract

The invention discloses a three-degree-of-freedom piezoelectric driving platform based on inertial impact, and aims at solving the problem of three-degree-of-freedom piezoelectric driving based on inertial impact. The three-degree-of-freedom piezoelectric driving platform based on inertial impact is mainly composed of an output platform (1), metal base plates (2), inertia mass blocks (3), piezoelectric wafers (4), a driver connecting shaft (5), an upper sliding plate (6), a lower sliding plate (7), cylindrical guide rails (8) and a fixing platform (9). The three-degree-of-freedom piezoelectric driving platform based on inertial impact is small in occupied space, simple in structure, high in inspection precision, easy and convenient to operate, easy to install, low in cost and reliable in performance.

Description

technical field [0001] The invention relates to a precision driver, more specifically, it is a three-degree-of-freedom piezoelectric drive platform based on inertial impact. Background technique [0002] The traditional motion platform is mainly driven by an electromagnetic rotating motor. This driving method is not practical, and the positioning accuracy or speed of the linear motion that can be realized is low and electromagnetic interference is generated. Piezoelectric actuators have obvious advantages in terms of positioning accuracy and response speed. Research on multi-degree-of-freedom positioning platforms based on piezoelectric actuators has become a hot topic in recent years. However, there are still many deficiencies in moving platforms based on different types of piezoelectric actuators. The piezoelectric driving platform of the present invention can not only realize the motion of three degrees of freedom, but also utilize the precise driving output of the piezo...
