Abstract

The invention relates to an asymmetric two-stage displacement amplification flexible micro-operation mechanism. The mechanism comprises a base body, a piezoelectric ceramic driver, an SR displacementamplification mechanism, a parallelogram lever amplification mechanism and a pre-tightening bolt, wherein the piezoelectric ceramic driver is installed on the base body through the pre-tightening bolt. The micro-operation mechanism only controls movement of one jaw, and the other jaw is connected with the base body and is fixed to be unmoved; the output end of the piezoelectric ceramic driver is connected with the input end of the SR displacement amplification mechanism through a flexible hinge IV, the SR displacement amplification mechanism is connected with the base body through a flexible hinge I, the output end of the SR displacement amplification mechanism is connected with the input end of the parallelogram lever amplification mechanism through a flexible hinge II, and the output endof the parallelogram lever amplification mechanism is connected with the jaws through a flexible parallel double-plate mechanism; and a metal strain gauge is adhered to the flexible parallel double-plate mechanism. According to the asymmetric two-stage displacement amplification flexible micro-operation mechanism, the asymmetric structure design is adopted, so that the structure of the micro-operation mechanism is compact, stable clamping is realized, and the defects of de-synchronic clamping and instability existing in symmetrical clamping are overcome.

Description

technical field [0001] The invention belongs to the field of micro-nano operation, and in particular relates to an asymmetric flexible micro-operation mechanism directly driven by piezoelectric ceramics and having two-stage displacement amplification. Background technique [0002] With the rapid development of micro-electromechanical systems (MEMS), the demand for micro-manipulation and micro-assembly technology is increasingly urgent. As a key component to realize micro-operation, micro-operation tool is the key link connecting micro-system and macro-system. With the development of micro-machining technology, microelectronics technology, MEMS, etc., the size of micro-miniature parts is getting smaller and smaller. Come higher demands. The rational design and manufacture of micro-operating mechanism is the key link to realize the operation of micro-small parts. [0003] The micro-operating mechanism used for the operation of micro-small parts is generally composed of a dr...
