ABSTRACT:
A fine positioning device is constructed of a parallel flexible-beam displacement mechanism and/or a radial flexible-beam displacement mechanism. The former displacement mechanism comprises a first rigid portion rigid against forces, a second rigid portion rigid against forces, plural parallel flexible beams connecting the first and second rigid portions together, and a first actuator adapted to have the plural flexible beams undergo bending deformation. The latter displacement mechanism comprises a third rigid portion rigid against torques, a fourth rigid portion rigid against torques, plural radial flexible beams connecting the third and fourth rigid portions together, and a second actuator adapted to have the plural flexible beams undergo bending deformation. The fine positioning device can obtain fine linear displacements and/or fine angular displacement with good accuracy. This invention also facilitates the construction of multi-axis positioning devices.
