Adaptive compliant assembly mechanism for cross-scale micro-parts

Abstract

The present invention discloses an adaptive compliant assembly mechanism for cross-scale micro-parts, which includes a compliant gripping mechanism, a first piezoelectric stack actuator, a second piezoelectric stack actuator, and a compliant cellular jaw. A first gripping arm and a second gripping arm are symmetrically arranged about an axis, and both have one end connected to a displacement amplification mechanism; the first piezoelectric stack actuator and the second piezoelectric stack actuator are respectively embedded in both sides of the displacement amplification mechanism; and, the compliant cellular jaw is detachably provided at free ends of the first gripping arm and of the second gripping arm. Compared with a conventional assembly mechanism, the adaptive compliant assembly mechanism for cross-scale micro-parts implements adaptive gripping operations of micro-parts with characteristic scales ranging microns to millimeters.
