Abstract

The invention belongs to the technical field of six-degree-of-freedom mechanical structures, and particularly relates to a six-degree-of-freedom platform and application thereof. The six-degree-of-freedom platform comprises a base, a movable platform and six driving devices for connecting the base with the movable platform, wherein any one of the six driving devices is used for driving the movableplatform to complete six-degree-of-freedom movement; each driving device comprises a hydraulic cylinder, a first hinge beam and a second hinge beam hinged to the first hinge beam, one end of the hydraulic cylinder is connected with the first hinge beam, the other end of the hydraulic cylinder is connected with the second hinge beam, and the hydraulic cylinder is used for changing the angle between the first hinge beam and the second hinge beam; and the first hinge beams and the second hinge beams are rotationally connected with the base and the movable platform correspondingly. According to the six-degree-of-freedom platform and the application thereof, the hinge structure formed by the first hinge beams and the second hinge beams is used for realizing the speed amplification of the linear movement of piston rods of the hydraulic cylinders, so that the stable and safe work of the hydraulic cylinders is guaranteed, and the service life of the hydraulic cylinders is prolonged.

Description

technical field [0001] The invention belongs to the technical field of six-degree-of-freedom mechanical structures, and more specifically relates to a six-degree-of-freedom platform and its application. Background technique [0002] The six-degree-of-freedom platform can realize six-degree-of-freedom movement in space, thereby simulating various space motion attitudes, and can be widely used in various training simulators, such as flight simulators, car driving simulators, earthquake simulators and Dynamic movies, entertainment equipment and other fields. In the processing industry, it can be made into six-axis linkage machine tools, robots, etc. [0003] At present, the hydraulically driven six-degree-of-freedom platform structure in the prior art is composed of a base, a moving platform, a hinge mounting seat for the base and the moving platform, and six hydraulic cylinders. The base is fixed relative to the ground, and the six hydraulic cylinders are linear hydraulic cy...
