Abstract

The invention relates to a machining device for a curvature radius-adjustable aspheric concave lens, and belongs to the field of precision machining. Through the macro-motion / micro-motion combined feed mode of a DC (direct-current) servo motor and a piezoelectric actuator, by combining a directional motion joint of revolution motion unit, the precise adjustment of a machining turning radius can be realized; the realization of the revolution motion of a spherical grinding head depends on the rotational degree of freedom, in two orthogonal directions, of a swing support frame and a spinning motion motor; meanwhile, through the precision follow-up adjustment of the vertical height of a concave lens test piece, the adjustment of the curvature radius of a machined lens can also be realized. As a vertical structure is adopted, the machining device disclosed by the invention is small in size and compact in structure and has small overall dimensions; the machining efficiency of the existing aspheric optical lens grinding technology can be effectively increased; the machining device is suitable for the precision machining of optical devices of a mini-type aspheric concave lens so as to broaden the application range of the mini-type aspheric lens in the field of space flight and aviation, military systems, optical communication and the like.

Description

technical field [0001] The invention relates to the field of precision machining, in particular to the field of precision grinding of aspheric lenses, in particular to an adjustable radius of curvature aspheric concave lens processing device. The aspherical concave lens processed by the device can effectively improve the effect of correcting the aberration of the spherical lens, improve the imaging quality, and improve the system identification ability. Aspherical lenses are widely used in aerospace, photography, military systems, optical communications and laser applications. The present invention can be used for the manufacture of miniature aspheric concave lenses because of its compact structure, low cost, easy operation and high processing efficiency. Provide processing methods. Background technique [0002] The application of aspheric optical components can increase the freedom of optical design, and play an important role in improving the imaging quality of the op...
