Six-degree-of-freedom self-adaptive displacement platform

A six-degree-of-freedom self-adaptive displacement platform comprises an alpha gamma elastic mechanism and a Z elastic mechanism which are mounted on a base, a Z displacement mechanism and an alpha gamma displacement mechanism which are mounted on the Z elastic mechanism, and a Z alpha gamma displacement platform supported on the alpha gamma displacement mechanism and the alpha gamma elastic mechanism, the XYbeta displacement platform is arranged above the Z alpha gamma displacement platform through an XYbeta elastic mechanism and an XYbeta displacement mechanism, is suitable for being mounted and used for fixing a mechanical part or a clamp, and can bear force or torque acting in a certain range in each direction through the part or the clamp; the Z displacement mechanism is combined with at least three sets of Z elastic mechanisms which are evenly distributed around the center of the base and are the same in structure through connecting pieces, and the alpha-gamma displacement mechanism is fixedly installed
