PIEZOELECTRIC MANIPULATOR Russian patent published in 2001 - IPC

FIELD: machine engineering, possibly systems for precision positioning. SUBSTANCE: piezoelectric grip has grip base, tie rods, brackets and screw. Piezoelectric drive is in the form of planar piezoelectric members. Magnetically conductive ball-type base is joined with grip base. One end of each planar piezoelectric member is rigidly connected with base. Other end of each piezoelectric member is connected with tie rod by means of bracket with possibility of sliding along piezoelectric drive. Tie rods are secured to grip base by means of screw. Such design of manipulator allows to enhance efficiency and reliability of gripping microobjects, to increase number of freedom degrees, to lower size and to prevent occurring of cross mechanical stresses in piezoelectric drives. EFFECT: improved design. 1 dwg
