车床齿轮零件的工艺规程及钻4-ф5孔夹具设计
摘要
车床在现代的工业制造体系中占据着绝对的领导地位,我们可以毫不客气的说一句,现代社会就是建立在一座座车床之上。车床主要是由主轴箱、进给箱、熘板箱、刀架、床身、尾架、光杠、丝杠等部件组成,然而这篇文章并不是关于这些主要结构部件,而是把目光放于更加难以引人瞩目的齿轮零件。虽然其看起来不重要,但不可否认的是车床齿轮零件在这之中起到了无比重要的作用。这是一篇关于车床齿轮零件工艺规程和夹具设计详细介绍的设计,其中包括零件的工艺分析、生产类型的确定、毛坯的选择、毛坯尺寸的确定、加工方法、加工工艺的确定等等。虽然其中有许多不足之处,但还是可以让读者对车床齿轮零件工艺规程和夹具设计有一个详尽的认识。
