  • Parallel positioning mechanism, especially for machining and/or manipulation and/or measuring
    Publication number: 20050135914
    Abstract: The invention relates to a parallel positioning mechanism, especially for machining and/or manipulation and/or measuring, consisting of a platform for the carrying and/or manipultaion with, for instance, a tool, a workpiece, a measuring device or the like, wherein the platform is connected with the machine frame by means of at least one positioning arm, characterised in that the platform (3) is joint-connected with at least one sliding guide (4) via at least three rotatable joints (11) of which at least two are arranged on a positioning arm (6) for the connection with the sliding guide (4), wherein the axes of rotation of the rotatable joints are mutually parallel. The direct connection may be replaced by a plurality of positioning arms (6), in which case the connection of the platform (3) with the sliding guide(s) (4) is achieved by means of at least four positioning arms (6).
