摘要
A parallel mechanism which has a holding bracket; a movable platform; and three branch joint assemblies of the same structure that are spatially arranged symmetrically about an axis disposed between the holding bracket and the movable platform. Each branch joint assembly has a connecting rod, a linear guide, a driving device and a carriage. The linear guide and the driving device both are secured on the connecting rod. One end of the connecting rod is connected with the movable platform through a hinge having three rotational degrees of freedom. The carriage and the linear guide are connected with each other by a sliding joint, and the carriage is connected with the holding bracket by a hinge having one rotational degree of freedom.
