Abstract

The invention discloses a lever-drive-based displacement resolution refinement micro-nano operating platform. The platform comprises a base body. A lever mechanism is arranged on the base body. The side, close to or far from a platform movement part, of the lever has variation in thickness. The two sides of the end, close to the base body, of the lever are each provided with a pressing block. The central axes of the two pressing blocks are located at the maximum thickness of the lever. The end, close to the platform movement part, of the lever mechanism is connected with the center of the edge of the platform movement part through a connecting rod. A circular hole for containing a preloaded spring is formed in the portion, facing the base body, of the end face of the side, far from the lever, of the pressing block located above the lever. The outer end face of the circular hole is matched with a preload nut. A circular hole for containing a piezoelectric ceramic actuator is formed in the portion, facing the base body, of the end face of the side, far from the lever, of the pressing block located below the lever. The circular hole is matched with a piezoelectric ceramic clamp nut. The platform movement part is connected with the base body through a platform guide mechanism. The center of the side, facing the lever mechanism, of the platform movement part is connected with a displacement measurement mechanism.

Description

technical field [0001] The invention relates to a micro-nano operation method with fine resolution, in particular to a design method for a fine-scale micro-nano operation platform with displacement resolution based on lever transmission, and belongs to the field of micro-nano operation. Background technique [0002] With the development of biological gene technology and nano-detection and manipulation technology in recent years, people have put forward new requirements for micro-nano manipulation technology with nanometer or even sub-nanometer resolution, and also challenged traditional ultra-precision manipulation methods. Especially in the 1990s, A.Midha and L.L.Howell proposed the concept of compliant mechanism, realized the innovation of transmission mechanism, greatly promoted the development of micro-nano operating platform design methods, and opened up a new design concept. The design and development of micro-nano manipulation platforms based on compliant mechanisms h...
