Abstract

The invention provides a six-freedom-degree parallel robot and relates to the field of medical instruments. The six-freedom-degree parallel robot comprises an upper platform (1), a lower platform (2),movement branch chains and a control device, wherein the upper platform (1) and the lower platform (2) are connected through the six movement branch chains; each movement branch chain comprises a first spherical hinge (3), a micro electric push rod (4), a lower connection part (5) and a second spherical hinge (6), the first spherical hinge (3) is connected with the upper platform (1), and the second spherical hinge (6) is connected with the lower platform (2); the control device is used for controlling movement of the six-freedom-degree parallel robot. The six-freedom-degree parallel robot disclosed by the invention has the advantages of strong mechanical strength, small accumulated error, small and compact structure design, small space occupation and obvious advantage in volume comparedwith a traditional parallel mechanism.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a six-degree-of-freedom parallel robot. Background technique [0002] With the continuous development of medical technology, the treatment measures for various diseases are constantly being introduced, and surgical robots for the medical field are gradually appearing in our field of vision. The core purpose of surgical robots is to adjust the position and posture of surgical instruments to replace doctors in completing some precise operations that are easy to plan. The device used by traditional surgical robots to adjust the position and posture of surgical instruments often adopts the mechanism configuration of series arms. inconvenient. The present invention designs a pose adjustment robot based on the configuration of a parallel mechanism, which can realize the actively driven six-degree-of-freedom position and attitude adjustment operation, and the mechanism is small and comp...
