HINGED PLATFORM MANIPULATOR Russian patent published in 2021 - IPC B25J1/06 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanisms of a parallel structure with a closed kinematic chain and can be used in machining centers, automatic lines, surgical medicine, where the constancy of a given orientation of the platform with the working body is required. The manipulator has a support base and a device for positioning the working body mounted on it in the form of a closed drive hinge-lever kinematic chain. The kinematic chain is made in the form of a hinged rectangle consisting of eight short double-hinged links of the same length, the tops of which are connected in pairs by means of four pairwise parallel long double-hinged links of the same length and eight double hinges with parallel axes of their angular rotation. One of the short double-hinged links of the hinge rectangle is interlocked with the support base.

EFFECT: simplified design of the manipulator and increased working area.
