Disclosed is a double-shaft quadrature cam driving type motion platform, comprising a substrate platform, a movable platform, and two modularization cam connecting rod driving sets which are arranged upon the substrate platform and configured in quadrature manner. When the two modularization cam connecting rod driving sets carry out a degree of freedom rotary movement at different times or at the same time in a synchronous manner, the movable platform carries out one or two degree of freedom rotary movements relative to the substrate platform. The double-shaft quadrature cam driving type motion platform is provided with a position feedback sensor at each shaft. The position feedback sensor is capable of sensing the motion displacement information when each shaft carries out one degree of freedom rotary movement, thus to raise precision of simulating double-shaft movement. The double-shaft quadrature cam driving type motion platform of the utility model does not adopt the hydraulic or air pressure technology a
