Abstract

The invention discloses a stepping giant magnetostrictive precision rotary driving device, which comprises a rotor, a stator, a clamping mechanism, a driving mechanism, a pre-tightening mechanism anda giant magnetostrictive multi-pulse signal controller, wherein the middle part of the stator is provided with the rotor; the clamping mechanism is located between the rotor and the stator; the innerside of the stator is provided with a mounting groove; the clamping mechanism is mounted in the mounting groove; the stator is divided to an upper layer and a lower layer, the stator comprises an upper stator layer, a lower stator layer and a base, the upper stator layer and the lower stator layer are connected with the base through three uniformly-distributed flexible hinges, and the base is fixed on a mounting table. An upper driving mechanism and a lower driving mechanism work alternately, and the output speed is doubled under the same condition; and when the upper stator layer and the lower stator layer rotate relative to the base, the flexible hinge generates deformation, deformation in one direction is only generated, the upper stator layer and the lower stator layer rotate steadily,and the output and the rotation of the system are steady.

Description

technical field [0001] The invention relates to a driving device, in particular to a stepping type giant magneto-induced precision rotation driving device. Background technique [0002] With the rapid development of science and technology, the requirements for product processing accuracy are getting higher and higher, especially in precision ultra-precision micromachining and measurement technology, microelectromechanical systems (MEMS), nanotechnology, semiconductor manufacturing, modern medicine and biological genetic engineering. , aerospace technology, military technology and other high-tech fields of science and technology are particularly important. In order to realize the precise and ultra-precision machining of product parts, it is necessary to provide a suitable high-precision driving device. The traditional drive devices, such as ordinary motors, screw nuts, turbine worms and other macro and large-scale drive devices cannot meet their accuracy requirements. There...
