The invention relates to the related technical field of mechanical rotating platforms, and particularly relates to a centrosymmetric multi-degree-of-freedom rotating platform. The technical problem that an existing multi-degree-of-freedom rotating platform simple in structure cannot keep the center not deviated easily is solved. The centrosymmetric multi-degree-of-freedom rotating platform comprises a base and a platform body, wherein hydraulic cylinders are arranged on the base; each hydraulic cylinder is hinged to the base through a first hinge shaft arranged left and right; a piston rod ofeach hydraulic cylinder is vertically arranged upwards; the end of each piston rod is hinged to a ball head rod through a second hinge shaft arranged front and back; rod bodies of the ball head rods are connected with the second hinge shafts; a ball socket is fixed to the platform body; a first limiting arc plate and a second limiting arc plate are fixed to the platform body; the axis of the firstlimiting arc plate coincides with the center axis of the platform body in the front-back direction; the axis of the second limiting arc plate coincides with the center axis of the platform body in the left-right direction; sand columns are arranged on the convex face of the first limiting arc plate and the convex face of the second limiting arc plate in a contact manner; and the stand columns arevertically fixed to the base.
Description
technical field [0001] The invention relates to the related technical field of mechanical rotating platforms, in particular to a center-symmetrical multi-degree-of-freedom rotating platform. Background technique [0002] In recent years, with the continuous development of high-end intelligence and VR technology, my country's multi-degree-of-freedom rotating platform technology has developed rapidly and is becoming more and more mature. Among them, for some specific occasions, the mechanical rotating platform only needs to rotate back and forth, left and right, and lift, but it needs to keep its center from horizontal deviation during the whole process, that is, it must always maintain center symmetry. Most of the existing multi-degree-of-freedom rotating platforms do not fix the rotation center during rotation, and always shift, which cannot meet the needs of the above-mentioned specific situations; a few structures can meet the needs of the above-mentioned specific situatio...
