A Harmonic Component Focusing Mechanism

Abstract

The invention discloses a harmonic component force focusing mechanism, which belongs to the field of space load technology and is used to solve the technical problem that the support rigidity and stability of the focusing mechanism in the prior art are difficult to guarantee. The invention is provided with a base for focusing The mounting base is installed inside the base, and both ends are slidingly connected to the base through linear guide rails, and the inside of the focusing mounting base is symmetrically rotated and connected with connecting rods; the eccentric force component part is provided with a force component base fixedly connected to the base; Both sides of the force base are rotatably connected with rotating shafts; the rotating shafts are fixedly connected with eccentric wheels that are rotatably connected with the connecting rod, and the connecting rod drives the focusing mounting seat to move linearly along the linear guide rail from both sides of the focusing mounting seat through the eccentric wheel; the driving part A drive shaft that can extend into the interior of the rotating shaft is provided; a flexspline is installed on the harmonic generator fixed at the end of the drive shaft, and the harmonic transmission of the flexspline meshes with the gear of the rotating shaft. The present invention has large support rigidity and high first-order mode , compact structure, lower requirements for parts processing and assembly precision.

Description

Technical field [0001] The present invention relates to the field of spatial load technology, and more particularly to a harmonic force focusing mechanism. Background technique [0002] At present, due to the very harsh application environment of the space optical system, the environment on the influencing factors of the optical system, such as changes in environmental temperature, changes in atmospheric pressure, system vibration, external impact, etc., will make the optical system The surface produces a certain degree of axial offset, thereby adversely affecting the image quality of the optical system; [0003] In the prior art, in order to ensure the image quality of the optical system, the axial position of the respective optical components in the optical system needs to be adjusted to correct the optical system focal surface defocus, and the focus is used. mechanism; [0004] With the resolution of spatial camera, the width requirements are increasing, and the volume of spat...

Problems solved by technology

[0004] With the increasing requirements for the resolution and width of the space camera, the volume of the space camera is getting bigger and bigger, so the support requirements for the optical components of the space camera are getting higher and higher, especially the focusing mechanism (moving parts), because Due to the particularity of the structure, it is not easy to guarantee the support rigidity and stability of the focusing mechanism
