Abstract

The invention discloses a micro-motion platform based on an amplifying mechanism, which includes a displacement amplifying mechanism. The displacement amplifying mechanism includes a triangular push plate and a right-angled trapezoidal plate arranged on the triangular pushing plate. The right-angled trapezoidal plate includes an upper bottom and a lower bottom. Hold on the right-angled side of the triangular push plate, the other right-angled side of the triangular push plate and the upper bottom of the right-angled trapezoidal plate are set on the same side, the angle between the hypotenuse of the triangular push plate and the right-angled side supported by the spring is 5 °‑35°, the inclined surface of the triangular push plate is provided with a chute along the moving direction of the right-angled trapezoidal plate, and the inclined surface of the right-angled trapezoidal plate is provided with a roller matching the chute. This application uses the cooperation of a triangular push plate and a right-angled trapezoidal plate to achieve displacement amplification. Since the movement of the two can be calculated based on the distance moved by the triangular push plate through geometric knowledge, the movement distance of the right-angled trapezoidal plate is calculated. Therefore, the motion of this application is more precise. Setting baffles on both sides of the right-angled trapezoidal plate can effectively control the range of movement.

Description

technical field [0001] The present invention relates to the technical field of micro-operation in advanced manufacturing, and more specifically, relates to a micro-motion platform based on an amplification mechanism. Background technique [0002] In recent years, with the continuous advancement of science and technology and industrial technology, the fields of microelectronics manufacturing, ultra-precision machinery manufacturing, micro-robot operation, precision measuring optical instruments, and biomedical operations have developed rapidly, and there is an urgent need to be able to position with nanometer precision and operating systems and equipment. In these fields, the micro-motion platform with nanometer precision is its core component, and its research is favored by scholars at home and abroad. Traditional mechanical structures, such as motors, gears, hinges, etc., cannot achieve nanometer precision due to the influence of assembly and motion clearance, friction, da...
