1、哈尔滨理工大学学士学位论文拨叉的CAD/CAPP设计及夹具PROE造型摘要我的毕业设计题目是拨叉的CAD/CAPP设计及夹具PROE造型,本次的毕业设计中我的论文分为三大部分:第一部分主要是拨叉的工艺规程设计。其中包括采用CAD完成了零件图,用PROE完成了毛坯图的绘制。完成了拨叉的工艺规程设计,主要包括确定设计类型,确定毛坯制造形式,制定工艺路线,选择机床及工艺设备,确定机械加工余量,工序尺寸和毛坯尺寸,以及切削用量和基本工时的确定。运用CAPP软件完成了拨叉的机械加工过程卡和工序卡。第二部分主要是拨叉的夹具设计。在这一部分的内容中,主要包括
2、零件的定位基准的选择,定位机构的设计,定位远见的尺寸的确定,定位误差的分析。设计夹具主要完成了加紧机构的设计,加紧力及夹紧机构的设计,夹紧力及夹紧方向的确定,以及所选择的夹紧元件。夹紧机构主要是采用螺母和压板的手动压紧,其定位和加紧机构简单,方便可靠。第三部分主要是采用Pro/engineer完成了拨叉的夹具造形。其中主要是详述了拨叉零件的绘制过程。关键词:拨叉;Pro/engineer;CAPP-V-哈尔滨理工大学学士学位论文TheCAD/CAPPDesignOfStirTheForkAndCreateTongsShapeWithPro/En
