Abstract
The invention relates to a fixed-rotation-center type multi-axis full-flexible hinge of a series structure. The fixed-rotation-center type multi-axis full-flexible hinge comprises an upper connectingpart, n single-axis flexible hinge bodies, n-1 middle connecting parts and a lower connecting part, wherein the rotation axes of the n single-axis flexible hinge bodies are intersected at one point inthe space, so that the multi-axis full-flexible hinge has a fixed rotation center, when the number of the flexible hinge bodies is different, the multi-axis full-flexible hinge can achieve differenthinge functions. when n is 2, the hinge can be used as a hooke joint, and when n is 3, the hinge can be used as a spherical hinge. The fixed-rotation-center type multi-axis full-flexible hinge of theseries structure has the advantages of being simple in structure, small in size, free of movement gaps and backlash, large in movement space range, easy to machine and integrate, low in cost and the like, and the design and integration problems of a multi-axis flexible hinge in application of micro-precision machines, micro-robots and the like are solved.
