常见典型夹紧形式所需夹紧力的计算和钻模板装置图例
一、常见典型夹紧形式所需夹紧力的计算https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125541_54592.png图1https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125552_68787.jpg图2https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125605_87734.jpg图3https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125621_88826.jpg图4https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125633_66843.jpg图5https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125645_61340.png二、钻模板钻模板有三种型式。第一种是位于钻模的上部而由钻模本身使它升降；第二种是可从原有位置转出，以便装卸工件；第三种是直接夹紧到工件上的。https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125654_23187.png图6A定出与槽有关的钻孔位置。https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125732_37891.png图7钻模板定出与两个已钻孔有关的附加孔位置。https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125739_34061.png图8三个要钻的孔与另外三个预先钻出的孔有关。钻模板从右面装入，然后紧。挡圈防止手柄从钻模饭脱出。https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125748_68223.png图9A由弹簧柱塞保持在它的升高位置，直至右边的定位销插入为止。https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125755_99557.png图10孔位于两个粗糙表面的中心。https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125803_73093.png图11插销锁紧可使钻模板快速拆卸。https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125809_85143.png图12钻夹具的钻模板碰撞压板A，随后使之压紧工件。https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125815_60330.png图13斜孔和水平孔定位与孔和顶面有关。https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125822_98339.png图14当摆式“C"形垫圈摆出螺钉以后，夹爪A和B即落下而收缩，钻模板就可取出。https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125828_58239.png图15钻模板定出与工件左侧面有关的钻孔位置。https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125835_16397.png图16当抬起手柄时，凸轮碰撞销A，因而抬高钻模板。https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125843_30743.png图17碟形螺钉转动1/4转，就可松开钻模板，使其得以抬起。https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125850_83582.png图18当钻摸板升高至足以使弹簧的中心线也就是B、C落位到A的另一侧时，钻模板就由弹簧使之保持在打开的位置。https://www.cwjoin.com/public/kindeditor/attached/image/20180714/20180714125857_51958.png图19转动手柄使凸轮B从A处移开，即可用手柄使钻模板摆起。
好吧 我来顶一下 支持一下！ 不错不错
