cq6232e车床尾架的三维实体设计与工艺设计(附件)
本课题是以CQ6232E车床尾架为研究对象，基本内容为CQ6232E车床尾架的三维实体设计和对该车床中的车床尾座的工艺设计。CQ6232E车床尾架的三维实体设计，先对该型号车床尾架进行拆卸，把所有零件的尺寸都测量齐全，运用三维软件solidworks绘图软件进行三维实体设计，零件图则由CAD完成。本次毕业设计课题的重难点在于车床尾架的工艺设计，具体步骤为：从尾架体零件的毛坯制造形式、选择粗基准与精基准、工艺路线制作、机加工余量及工件毛坯的确定，选择合适切削用量、基本工时等方面进行工艺分析，明确各个零部件的加工工艺过程以及流程，为尾架零部件的加工装配提供正确合理的指导。
