Abstract

The invention discloses a micro-motion platform for improving the resolution of a linear motor based on a flexible inclined beam. The micro-motion platform is provided with a base, six inclined beam components, two transition plates, an input plate, an output plate and two guide beam components. An output rod is mounted on the output plate of the micro-motion platform, and an output shaft of the linear motor is connected with the input plate of the micro-motion platform so as to apply the drive force to the micro-motion platform. The micro-motion platform disclosed by the invention has the functions of a two-level speed reducer in the same plane, improves the resolution of the linear motor by use of the motion reducing principle, and overcomes the shortcoming of lower resolution of the linear motor.

Description

Technical field [0001] The present invention relates to a micro-motion platform, and more particularly, to a micro-motion platform based on a flexible inclined beam for improving the resolution of a linear motor. Background technique [0002] In precision engineering, the end effector is generally required to have a nanometer resolution, and the resolution of the end effector depends on the resolution of the selected driver. At present, the most common high-precision drivers mainly include piezoelectric ceramics and voice coil motors. [0003] Piezoelectric ceramics is an inorganic non-metallic material that converts mechanical energy and electrical energy into each other. When pressure is applied to the piezoelectric material, it will generate a potential difference, and vice versa, when a voltage is applied, mechanical force is generated. It has the advantages of stability, continuity, fast response, nanometer precision and large output force, but the range of motion is very sma...
