摘　　要：叉架轴是密码锁中重要的零件之一,结构复杂,针对原加工工艺方案中,装夹次数多,定位精度差,钻头易折断的问题.提出使用软爪和加长型软爪,并改变轴耳孔加工方法,在一台设备上(山崎马扎克QTC300MY L/1000车削中心)加工叉架轴的加工工艺方案.改进工艺方案使装夹次数减少一次,加工效率提高22%,定位精度达到100%,钻头折断率由10%降为0,废品率由10%降为0.The fork shaft is one of the important parts of the password lock with complex structure.In original process,the number of clamping times is large,the positioning accuracy is poor,and the drill bit is easy to break.The fork shaft process on one equipment(Yamazaki Mazak QTC300MY L/1000 Turning Center)is proposed,using soft claw and lengthened soft claw and changing the processing method of ear hole.The improved processing scheme reduces the clamping times by one time,improves the processing efficiency by 22%,the positioning accuracy reaches 100%,the breaking rate of the drill bit is reduced from 10%to 0,and the scrap rate is reduced from 10%to 0.
