A micro-motion platform with a two-stage amplification function and a working method thereof

Abstract

The application belongs to the technical field of micro-motion devices, and provides a micro-motion platform with secondary amplification function and a working method thereof. The driving device comprises a central column arranged on a base, a plurality of first amplification mechanisms arranged on the central column, a plurality of second amplification mechanisms connected with the plurality of first amplification mechanisms, and a plurality of hook hinges connected with the plurality of second amplification mechanisms. A driver is arranged on each first amplification mechanism, and the plurality of hook hinges are connected with the object table. The driver drives the first amplification mechanism to act, the first amplification mechanism drives the second amplification mechanism to act, thereby driving the hook hinges to act, and the hook hinges at different positions drive the object table to swing. The combination of the first amplification mechanism and the second amplification mechanism has a secondary amplification function, so that the swing range of the platform output is larger, and compared with the arrangement mode that the amplification mechanism directly drives the platform, the axial structure of the platform is more compact.
