[0006] The six-axis free-moving assembly includes three circumferentially distributed upper hinge seats fixed to the lower surface of the upper support plate, three circumferentially distributed lower hinge seats fixed to the upper surface of the lower support plate, six linear motion cylinders connected between the upper and lower support plates, and telescopic drive motors that control the extension and retraction of each linear motion cylinder. The top two of the six linear motion cylinders are hinged to the lower end of an upper hinge seat, and the bottom two of the six linear motion cylinders are hinged to the upper end of a lower hinge seat. The six linear motion cylinders on the upper and lower hinge seats are staggered. By controlling the extension and retraction of the six linear motion cylinders, the upper support plate can be controlled to move freely in six axes relative to the lower support plate.
