Abstract

The invention discloses a micro-displacement amplification and conversion device. The micro-displacement amplification and conversion device comprises a base (1), a micro-displacement amplification mechanism (2) and an intelligent material driver (8) and also comprises a slight zero adjustment mechanism (3), a pre-tightening adjustment mechanism (4), a linear bearing (5), a displacement conversion mechanism (6) and an output shaft (7), wherein the micro-displacement amplification mechanism (2) is used for amplifying micro-displacement generated by the intelligent material driver (8) according to a lever principle and structural elastic deformation, the displacement conversion mechanism (6) is used for converting linear displacement output from the micro-displacement amplification mechanism (2) into angular displacement to be transferred to the output shaft (7) through a key under the joint effects of a transmission rod (15), a flexible hinge (16), a connection rod (17) and an eccentric wheel (18), and the pre-tightening adjustment mechanism (4) and the micro-displacement amplification mechanism (2) are jointly used for applying pre-tightening force onto the intelligent material driver (8). The micro-displacement amplification and conversion device adopts an integrated design and is compact and high-efficiency in structure, and the function is full and simple.

Description

technical field [0001] The invention relates to a micro-displacement amplification device, in particular to a micro-displacement amplification conversion device. Background technique [0002] The new micro-actuator system designed based on the strain characteristics of intelligent materials such as magnetostrictive effect and inverse piezoelectric effect has been widely used due to its advantages of high precision, high dynamics and high reliability. The micro-displacement amplification device is a key component of this type of system. Its function is to amplify the micron-level displacement output by the smart material driver into millimeter-level displacement. Commonly used micro-displacement amplification devices include: a base, a micro-displacement amplification mechanism, and an intelligent material driver. The base is the fixed foundation of the device. The micro-displacement output by the driver is the amplified target. Existing micro-displacement amplification dev...
