Structure of cable and/or pipe arrangement applied in parallel link mechanism

摘要

A structure of a cable and/or pipe arrangement for a parallel link mechanism where a fixed member 1 and a movable member 2 are provided, both of them are connected to each other by a plurality of link members 3 arranged in parallel, and the movable member 2 is moved relative to the fixed member 1 by driving the respective link members 3. A plurality of cables and/or pipes 10 led to the fixed member 1 from the outside of the parallel link mechanism are respectively bent away from the fixed member 1, the respective cables and/or pipes 10 being clamped by cable/pipe clamping means 20 provided on the fixed member 1 so as to maintain the cables and/or pipes 10 in their bent states. The respective cables and/or pipes 10 are connected to drive control devices 4a-4f for performing stretching/retracting operations of the respective link members 3 from the clamped positions of the cables and/or pipes 10.
