Embodiment

[0018] as attached figure 1 to attach figure 2 As shown, a lever cascaded nanoscale displacement generating device includes a stepper motor 1, a first fixed base 2 and a second fixed base 3 spaced apart from the first fixed base 2, and the stepper motor 1 is connected at a point There is a stepping motor controller 4, and the stepping motor controller 4 is electrically connected with a computer 5. The stepper motor 1 is connected with a threaded rod 6 through an adapter plate, and the threaded rod 6 is threaded with a first slider 7 that is slidably connected with the first fixed base 2. The first slider 7 adopts a metal slider, which can realize the direction of rotation. Transformation of linear translation. First slide block 7 is inserted with first rigid conical top 8 by pin, is provided with the first lever 9 that turning point is outside the first fixed base 2 on the locus of motion of the first rigid conical top 8, the first lever 9 The left side is provided with a ...

Abstract

The invention discloses a lever cascade type nanometer magnitude displacement generating device, and particularly relates to the technical field of precise distance measuring devices. The device comprises a stepping motor, a first fixed base and a second fixed base, the stepping motor is installed on the first fixed base, a threaded rod is connected to the stepping motor, a first sliding block in sliding connection with the first fixed base is in threaded connection with the threaded rod, a first rigid conical tip is connected to the first sliding block in an inserted mode, a first lever with a rotating point outside the first fixed base is arranged on the motion trail of the first rigid conical tip, a second rigid conical tip is arranged on the other side of the first lever, a second lever with a rotating point outside the second fixed base abuts against the second rigid conical tip, a third rigid conical tip is arranged at the other side of the second lever, and the second fixed base is in sliding connection with a to-be-tested moving sliding block. According to the technical scheme, the problem that a common stepping motor cannot achieve the nanometer magnitude is solved, and the motor can be used for generating nanometer-magnitude displacement.

Description

technical field [0001] The invention relates to the technical field of precision ranging devices, in particular to a lever cascaded nanoscale displacement generating device. Background technique [0002] Space and time have always existed in all aspects of human social activities, from the height scale of the human body at the meter level, to the length of an ordinary ruler with millimeter resolution, to the conventional optical microscope at the micron level, to the scanning tunneling microscope at the nanometer level, etc. Time and time again, it develops human cognition of the microcosm and promotes the development of human social civilization from low to high. [0003] The stepper motor relies on the change of air gap permeance to generate electromagnetic torque, and converts the electric pulse signal into the corresponding angular displacement or linear displacement of the motor technology. Every time a pulse signal is input, the rotor rotates an angle or advances one ...
