Other AbstractThe utility model relates to a 4-degree-of-freedom(DOF) parallel mechanism for realizing two-dimensional rotation and two-dimensional translation movement. The mechanism consists of six groups of guide rails, a movement platform, six transmission rods and six sliding blocks, wherein the six groups of the guide rails are vertically arranged on a bedplate respectively the first to the six sliding blocks are respectively arranged on the six groups of the guide rails in sequence the one end of each transmission rod is respectively connected with each sliding block via a kinematic pair, the other end thereof is respectively connected with the movement platform via a composite spherical hinge the first and the second are respectively driven by a group of linear driving unit, the other four blocks are divided into two groups with each having the two sliding blocks which are fixedly connected with each other via connecting pieces at the same side of the movement platform to form two branched chain structures, each is driven by a group of linear driving unit. The utility model has high transmission efficiency, good rigidity, sound stress performance and wide application range.
