Parallel mechanism structure for controlling three-dimensional position and orientation

摘要

Disclosed is a parallel mechanism structure for controlling three-dimensional position and orientation. In the parallel mechanism structure according to the present invention, three links are connected to the main spindle of the mechanism and driven in vertical and horizontal direction, with a consecution that the main spindle connected to the three links achieves the six d.o.f motions. The structure includes three links comprised of a first link transferred along a circular vertical guide and second and third links transferred along corresponding rectilinear vertical guides and a circular horizontal guide on which the circular vertical guide and the two rectilinear vertical guides are horizontally transferred.
