摘要 本夹具设计的零件是偏心泵体，偏心泵在实际的生产中运用的还是比较频繁的，实现了相应的动作传递了相应的动力等等。泵体是偏心泵的核心组成部分，偏心泵能够正常的工作，偏心泵体的功不可没的。泵体实现不一样的动作，最终传递相应的动力或者运动等。 本次专用夹具设计的是钻Φ16孔钻床专用夹具，使用的钻床为Z3040摇臂钻床，专用夹具的设计内容主要有，明确六点定位原理，设计适用于本工件的定位和夹紧方案以及原件；设计机床连接体—夹具体；选择对刀装置并进行相应的计算等。当然了在对专用夹具设计之前，还对零件的加工工艺进行了设计。依据确定的余量绘制毛坯图，设计加工工艺路线，选择了加工工艺装备；根据计算得出的数值填写工序卡等。 关键词：偏心泵体；钻Φ16孔；Z3040摇臂钻床；专用夹具；加工工艺； Abstract The parts desig
