1 零件的相关技术要求我厂生产的轻型车床中 ,床鞍上用于消除丝杠间隙的铜螺母如图 1所示 ,其中粗实线是一个件 ,双点划线是另一个件 )。设计要求将两件按孔距 2 3ｍｍ固定在一起后 ,再同时加工Ｔ19× 2 5 - 9左螺纹孔 ,以保证两件同轴度。实际生产中 ,考虑其加工工艺性 ,我
1 parts of the technical requirements of the light lathe I plant production, the saddle on the elimination of lead screw clearance copper nut shown in Figure 1, in which the thick solid line is one piece, two-dot chain line is the other piece). Design requirements of the two pieces of the hole by 2 3mm fixed together, and then processing T19 × 2 5 - 9 left-hand thread hole to ensure that the two pieces of coaxiality. In actual production, considering its processing technology, I
