  • Class of over-constrained two-rotation parallel mechanism with same kinematics
    Patent number: 11506266
    Abstract: The present invention relates to a class of over-constrained two-rotation parallel mechanism with same kinematics, which comprises a base, a moving platform and four branches connecting the base and the moving platform, wherein the base and the moving platform are equilateral triangles, both ends of each of the first branch, the second branch and the third branch are respectively connected to end points of the base and the moving platform, both ends of the fourth branch are respectively connected to center points of the base and the moving platform, the first branch and the third branch both consist of a first rotating pair. The parallel mechanism of the present invention has a large rotation space and high rigidity, and can be used for positioning equipment such as missile launchers.
