[0003] The existing flexible displacement amplification mechanism is often not compact enough, and the stroke and the overall rigidity are mutually restricted, which cannot meet the needs of high-precision high-speed processing equipment, flexible robots and other fields.
If the stroke and the overall rigidity are increased at the same time, it is easy to produce coupling errors that are difficult to eliminate, and the accuracy will decrease

Abstract
The invention discloses a full-flexible hinge micro-displacement amplification mechanism, and belongs to the field of the flexible micro-nano. A piezoelectric ceramic is fixed in the middle of a rightbase of a support frame, and is connected with the middle part of a first lever of an amplification mechanism; a top end of the first lever is connected with the right base, and the lower side of thefirst lever is connected with the lower side of a second lever; a bottom end of the second lever is connected with a base of the support frame, the upper side of the second lever is connected with the lower side of a third lever, the bottom end of the third lever is connected with a middle base of the support frame, the top end of the third lever is connected with the bottom end of a right displacement conduction rod, and the right displacement conduction rod top end is connected with the bottom of an output platform. The full-flexible hinge micro-displacement amplification mechanism disclosed by the invention is a symmetric structure, a left side structure and a right side structure are completely same; the connection between the levers is the arc flexible hinge connection. The amplification mechanism can provide enough driving force for the whole mechanism, the structure is more compact, the entire rigidity is greater, the movement is stable, free from lubrication, zero in lagging,high in precision, and free from assembling error, capable of basically eliminating the coupling error and more suitable for the engineering demand.
Description
technical field [0001] The invention belongs to the field of flexible micro-nano, and in particular relates to a fully flexible hinge micro-displacement amplification mechanism. Background technique [0002] Flexible mechanism is a new type of mechanism that uses elastic deformation of materials to transmit or convert motion, force or energy. In the fields of bionic machinery and robots, flexible mechanisms are playing an increasingly important role, and such mechanisms are often called flexible bionic mechanisms. [0003] Existing flexible displacement amplification mechanisms are often not compact enough, and the stroke and the overall rigidity are mutually restricted, which cannot meet the needs of high-precision high-speed processing equipment, flexible robots and other fields. If the stroke and the overall rigidity are increased at the same time, it is easy to produce coupling errors that are difficult to eliminate, and the accuracy will decrease. [0004] This patent...
