摘要
这次设计的是CA6140车床(831009)杠杆,包括零件图、毛坯图、装配图各一张,机械加工工艺过程卡片和与工序卡片各一张。首先我们要熟悉零件和了解其作用它们。它们位于厢体内部,传递扭距,帮助忙乱变速机床工作台的运动方向。然后,根据零件的性质和零件图上各端面的粗糙度确定毛坯的尺寸和械加工余量。最后拟定拨差的工艺路线图,制定该工件的夹紧方案,
画出夹具装配图。
就我个人而言,我希望能通过这次课程设计,了解并认识一般机器零件的生产工艺过程,巩固和加深已学过的技术基础课和专业课的知识,理论联系实际,从中锻炼自己分析问题、解决问题的能力,为今后的工作打下一个良好的基础,并且为后续课程的学习打好基础。
Abstract
This time I design the lathes of the shift forks CA6140(831009), including that the part pursuing , the blank pursues , assembling pursues , the machine work procedure card the working procedure card every sheet .We should know the part very well and know its effect first , it is worked in anization which is used for change the speed in a lathe, and the mainly role of the part is alter the speed. Then, we design the dimension of the blank and instrument process a margin of the part according to part character and the harshness of each face .Finally, I design the handicrafts route picture of the shift forks, work out the fastening motion scheme being workpiece's turn , draw up clamp assembling picture.
As far as my i
