Abstract
The precious rotary positioning platform comprises a base, a moving platform, a guiding mechanism and two groups of driving device. The said base, moving platform and guiding mechanism are processed from a block of material and made into an integrally assembled compliance mechanism. At the two opposite sides of the base is provided respectively with a circular hole for mounting two groups of driving mechanisms which are arranged at the two opposite sides of the moving platform and staggered each other. In any one group of driving device there are two balls and a spring are provided in the said circular holes. An extending brake is fixed on the base through a fixing member. The forehead of the extending brake compresses tightly the ball which compresses tightly the spring which compresses tightly another ball which compresses tightly the moving platform. Advantage: obtained high-precision output under low-precision input, simple control and operation of platform and low cost.
