Combined type centering edge grinding machine

Abstract

The invention relates to a combined type centering edge grinding machine which is a novel centering technology combining a mechanical centering principle and an optical centering principle, can monitor the bounce size of the sphere center of a lens on the mechanical centering edge grinding machine in real time through a displayer, and grinds an outer circle after the bounce size of the sphere center is adjusted to an allowable range. Therefore, the machining range of the mechanical centering edge grinding machine is expanded, and the lens with the poor centering coefficient can still be machined on the mechanical centering edge grinding machine. The equipment comprises a traditional mechanical centering edge grinding machine, a compact reflective eccentric instrument and a connecting part, wherein the eccentric instrument may adjust the horizontal and vertical positions, then adjust the distance from a reflective prism to the lens, and align the optical axis of the eccentric instrument with a machine tool spindle. According to the reflection type centering edge grinding machine, the precision of the mechanical centering edge grinding machine is greatly improved, the machining range of the mechanical centering edge grinding machine is greatly expanded, operability is high, cost is low, resources are effectively saved, enterprise cost is reduced, and the combined type centering edge grinding machine is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of mechanical centering and edging of optical lenses, in particular to a compound centering and edging machine. Background technique [0002] Optical lenses are key components of various optical imaging systems. The quality of the optical lens directly affects the performance of the imaging system, and even determines its success. Because the optical lens must have various aberration defects in theory, a more complex combination of optical lenses with different shapes and different materials is often used in the design of the optical lens. The purpose is to correct various aberrations of the optical lens in order to obtain high-quality imaging. quality. However, there are still many errors from the completion of the design to the actual manufacture. In the process of actually manufacturing optical lenses, it is inevitable that there will be various parts manufacturing errors, lens assembly errors, and so o...
