摘要 加工行业发展的很快，有好多非标零件需要生产，因为产品不是规则的，装夹起来不是那么的便利，所以，要专门设计一个专用夹具，这样加工才能很好的继续。 本课题研究的对象是B6065牛头刨床推动架。设计任务是对其进行加工工艺分析及专用夹具设计。对工艺流程进行设计，首先把零件图画出来，对产品的构造进行分析，要明确产品需要加工多少，生产余量是多少，将坯料的图纸画出来，最后将工艺路线还有工序卡都写出来，算出来生产时候切削量是多少。 专用夹具设计有铣6X9.5槽。对夹具进行设计的时候，要知道怎么样对产品进行装夹，如何进行定位，如何进行夹紧。定位是有了哪些零部件，夹紧使用了哪些零部件，对产品进行定位必然会有误差出现，对它进行分析，需要画的图纸有夹具的装配图，非标零件图，将的详细内容写出来。 关键词：CB6065牛头刨床；推动架；加工工艺；铣6X9.5槽 Abstract With the rapid developme
