A kind of flexible micro-operation mechanism

Abstract

The invention discloses a flexible inching operation mechanism based on a five-rod mechanism. The flexible inching operation mechanism is characterized by comprising two piezoelectric ceramic drivers, two spherical joints, three 7-shaped short flexible chains, one rigid connection block, one flexible parallelogram structure, one mobile platform, one 7-shaped long flexible chain, one rigid supporting frame and one base; the interior of the rigid supporting frame is hollowed out according to the distribution requirements of flexible structures, all the parts except for the base are designed inside a cavity of the rigid supporting frame, the spherical joints are installed at the top ends of the piezoelectric ceramic drivers, and the tail ends of the piezoelectric ceramic drivers are rigidly fixed to the side wall of the rigid supporting frame through threads; the spherical joints abut against the waist parts of the 7-shaped short flexible chains for forming Hertz contact; each 7-shaped short flexible chain is composed of two vertical short beams and one 7-shaped rigid short beam between the two vertical short beams; the mobile platform is of a half-round structure, and the contour of the mobile platform is divided into a linear side wall and an arc-shaped side wall.

AI Technical Summary

Problems solved by technology

In the field of micro-manipulation, the mechanism is required to implement a large range of motion capabilities in the working space and precise positioning accuracy. In order to have a sufficiently flexible motion output capability, the end-execution platform in the mechanism generally needs multiple flexible chains to support, and a single branch chain often causes flexibility. The inaccuracy in the movement direction of the end of the mechanism affects the accuracy and range of movement of the mechanism
