Fillet-type-flexible-hinge-based micro-displacement high-power magnification mechanism and method thereof

Abstract

The invention discloses a fillet-type-flexible-hinge-based micro-displacement high-power magnification mechanism and a method thereof. A first fixing column is connected with a first supporting arm through a first flexible hinge, one end of the first flexible hinge is located at the middle of the first fixing column, and the other end of the first flexible hinge is located at the left side of the first supporting arm; and a displacement input column is connected with the first supporting arm through a second flexible hinge, a second fixing column is connected with a second supporting arm through a third flexible hinge, the first supporting arm is connected with the second supporting arm through a fourth flexible hinge, and one end of the fourth flexible hinge is located at the right end of the first supporting arm close to the edge of the first supporting arm. According to the fillet-type-flexible-hinge-based micro-displacement high-power magnification mechanism, the problems of poor flexibility, short tail-segment stroke, low magnification power and the like in the prior art caused by the fact that magnification equipment adopting flexible hinges only concerns for the linearity and precision of amplification and insufficiently considers the flexibility, end stroke and magnification power of the mechanism are solved. The magnification mechanism disclosed by the invention is simple in structure and convenient to manufacture and has the characteristics of good flexibility, long tail-segment stroke, high magnification power and the like.

Description

technical field [0001] The invention relates to an amplifying mechanism and a processing method thereof, in particular to a micro-displacement high-magnification amplifying mechanism and a method based on a rounded corner flexible hinge. Background technique [0002] Current smart materials such as piezoelectric ceramics and magnetostrictive materials have the characteristics of fast response, strong output force, large strain, high power density and good reliability, so they have been widely used in many fields. However, affected by the performance of the material itself, the displacement it can produce is very small, and a corresponding amplification mechanism is required to amplify the displacement generated by it before it can be applied in practice. [0003] At present, the amplifying mechanism using a conventional hinge is not suitable as a micro-displacement amplifying mechanism due to its defects such as large air travel, large friction, and slow response. The flexi...

AI Technical Summary

Problems solved by technology

However, previous amplification devices using flexible hinges paid more attention to the linearity and accuracy of amplification, and insufficient consideration was given to the flexibility of the mechanism, terminal stroke and magnification. And other problems, which limit its application in some occasions that do not require high precision but require high magnification and stroke
