Problems solved by technology

Since the range of motion of the ball joint is limited by the size of the pin, the steepness of the aspheric optical parts that can be "flexibly" adapted by the structural form of the ball hinge plus the pin is limited; while the adaptability of the universal joint is steep Although the degree is not limited, since the grinding head needs to maintain a constant processing pressure output during the working process, it may cause pressure instability or uneven force when processing high-steep aspheric o

Abstract

The invention discloses a polishing device with two swing shafts for high-gradient aspheric optical parts. The polishing device comprises a two-swing-shaft mechanism and a two-rotor polishing mechanism. The two-swing-shaft mechanism comprises a deflection component and a pitching component which is arranged at a deflection output end of the deflection component. The two-rotor polishing mechanism is arranged at a pitching output end of the pitching component. By means of the polishing device with two swing shafts for high-gradient aspheric optical parts, the Gaussian removal function which is constant in pressure and stable in removal performance can be provided at any time, and the efficiency is high and the accuracy is easy to achieve for processing of high-gradient aspheric optical parts.

Description

Technical field [0001] The invention relates to the technical field of optical parts processing, in particular to a double pendulum shaft polishing device used for high-steep aspheric optical parts. Background technique [0002] In the optical system, spherical optical parts cannot be ideally focused and imaged. Traditional spherical optical parts have the characteristics of fixed radius of curvature, uniform arc, low price and simple manufacturing. However, there are principle aberrations in the optical path structure, which can easily cause imaging deformation, blur, and narrow field of view. Compared with spherical and flat optical parts, aspherical optical parts introduce more design parameters in the optical system, so that the design of the optical system has greater flexibility, can correct aberrations, improve image quality, and expand the view. Field, and simplify the structure of the optical system and reduce the weight. The advantages of aspheric optical parts have m...
