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.

摘要： A six-degree-of-freedom parallel mechanism is provided for expanding a grade of a spindle. The parallel mechanism has a spindle that turns round a workpiece at a tilting angle of 90.degree. in a workspace, to thereby allow a machining for both vertical and horizontal planes of the workpiece, and a vertical turning process, by a single machining center. A six-axis multi-machining type machining center embodying the parallel mechanism of the present invention is also disclosed. An over-actuated multi-machining type machining center further including over-actuated actuators is presented to solve a problem of driving joints' singularity caused by the parallel mechanism.
