Problems solved by technology

In practice, when the piezoelectric ceramic actuator operates more than half of the range, the response time will be relatively long due to the hysteresis effect, and it needs to supply high power to the piezoelectric ceramic, which will affect the real-time performance of micro-positioning

Abstract

The invention provides a piezoelectric ceramics driven micro displacement amplification mechanism and a using method thereof. Piezoelectric ceramics elongate to push a first flexible rod to inclined leftwards, when an electrorheological fluid in a first electrorheological fluid box is in a liquid state and an electrorheological fluid in a second electrorheological fluid box is in a solid state, anoutput arm moves leftwareds, and when the electrorheological fluid in the first electrorheological fluid box is in a solid state and the electrorheological fluid in the second electrorheological fluid box is in a liquid state, the output arm moves rightwards. The electrorheological fluid boxes are additionally arranged to control the displacement direction, displacement is changed from simple unidirectional output to bidirectional output, the displacement directions include forwarding and backing directions, and a simple method is provided for reciprocating movement within a small range.
