FIELD: mechanical engineering.
SUBSTANCE: invention relates to mechanisms for obtaining a given movement of the output element. The six-movable spatial mechanism of a parallel-series structure includes a rack on which four kinematic chains are installed. The chains are connected by means of rotational hinges to the frame, inside of which a platform is installed by means of translational hinges. The output link associated with the output element is installed. A frame with vertical guides is rigidly mounted on the rack, forming translational hinges with sliders, and the sliders in pairs are rigidly connected to each other by crossbars forming rotational hinges with the connecting rods and the frame. A carriage is installed between the platform and the output link, forming translational hinges with the platform, and rotational hinges with the output link. The output link forms a rotational hinge with the output element.
EFFECT: increase in load capacity.
