摘要

为了提高鱼眼镜头中透镜的加工效率, 设计了三片不胶盘夹具代替传统的刚性盘和弹性盘进行精磨和抛光, 提高了生产效率;采用熔化后的聚氨酯代替上盘胶, 可避免抛光时胶层对面型的影响;运用皮筋代替设备上的压力表, 提高了下摆机精磨和抛光时光圈的稳定性;规范精磨及抛光工序中模具的使用, 有利于生产效率的提高;通过对抛光和定心磨边先后顺序的调整, 可有效避免磨边过程中在零件表面产生压痕和划痕;通过对涂墨夹具结构的改进, 提高生产效率, 降低劳动强度。在生产中, 三片不胶盘夹具的生产效率相对较低, 如何成功研制出多片不胶盘夹具是下一步工作的重点。

Abstract

In order to improve the processing efficiency of lens in fisheye lens, traditional rigid disk and elastic disk are replaced by designed three-piece nonblocking fixture for fine grinding and polishing. The production efficiency is enhanced. In the polishing process, the effect of glues on surface form can be avoided by utilizing fused polyurethane instead of blocking glues. The stability of aperture in polishing and fine grinding processes of hem machine is enhanced by using the rubber band instead of the pressure gage in the equipment. The regulatory usage of molds in polishing and fine grinding processes is in favor of improving production efficiency. The impact of impressions and scratches on the surfaces of the parts caused by edging process are avoided effectively by adjusting the sequence of polishing and mechanical centering and edging. The production efficiency is enhanced and the labor intensity is reduced by improving the structure of fixture for smearing ink. In production, the production efficiency of three-piece nonblocking fixture is lower, and how to successfully develop multi-piece nonblocking fixture is the focus of the further work.
