CA6140车床拨叉加工工艺及铣断夹具设计

摘要

拨叉的加工质量将直接影响机器的性能和使用寿命。本次设计旨在提高CA6140车床拨叉的加工效率，由此我们首先对拨叉的结构特征和工艺进行了仔细的分析，然后确定了一套合理的加工方案，加工方案要求简单，操作方便，并能保证零件的加工质量。在制定加工工艺规程的顺序如下：
1.分析零件；
2.选择毛坯；
3.设计工艺规程：包括制定工艺路线，选择基准面等；
4.工序设计：包括选择机床，确定加工余量，工序尺寸及毛坯尺寸，确定切削用量及计算基本工时等；
5.编制工艺文件。
此外，为了提高劳动生产率，降低劳动强度，保证加工质量，需设计专用夹具，本次设计选择了第六道工序铣断双体的专用夹具设计，以满足加工过程的需要。
