CC2233压盖工艺分析及钻4-Ф10孔夹具设计 摘要 在经济飞速向前的当下，制造业快速发展的今天。非标零件的尺寸、结构也千变万化。以往设计的通用夹具，越来越多的面临淘汰。所以专用夹具的设计与生产越来越广泛。专用夹具的研究其主要内容有定位方案、夹紧方案的确定，定位元件、夹紧元件的选择，导向装置的选择等等。 本次设计研究的对象是CC2233压盖。设计内容包括2个方面：1、工艺分析；2、钻4-Ф10孔钻床专用夹具设计。CC2233压盖是CC系列卧式车床上不可或缺的零件之一，为机床及零部件的正常运转提供保障。 从零件结构分析入手，合理选择定位基准，各种刀具参数选择以及切削用量的选择等。在安排工艺过程时，根据加工要求不同，需要进行粗精加工。另外还确定了切削参数，加工工时，填写工艺过程卡片和工序卡片。专用夹具设计内容有：确定定位方案及元件，确定夹紧方案及元件，确定导向装置，计算切削力及夹紧力等。 关键词：CC2233压盖、工艺、4-Ф10孔、钻床、专用夹具 ABSTRACT At a time of rapid eco
