ABSTRACT:
A compliant mechanism is provided for accurate and precision alignment of mechanical component parts, surfaces or assemblies and the like, where low-cost, accurate, and repeatable alignment are desired. The compliant mechanism may be used in applications that require high precision alignment and where the relative location of coupled components must be variable or adjustable. The compliant mechanism includes a stage coupled to a plurality of hinges, at least one tab coupled to one of the hinges, and a support coupled to the tab. The relative position of the stage and the support may be adjusted by actuating (i.e., displacing) the tab(s) or other parts of the structure, to enable controlled movement in six degrees of freedom therebetween.
