曲轴箱箱体的工艺及工装说明书——44页
摘 要
曲轴箱是一种典型的箱体零件,它的作用是容纳和支承其内的所有零部件,保证它们相互间的正确位置,使彼此之间能协调地运转和工作。曲轴箱的分割面与轴承孔,箱盖左右两侧缸孔精度要求较高,因此在安排工艺过程时,就需要把各主要表面及孔的粗精加工工序分开。在制定曲轴箱工艺过程中,还确定了切削参数,工时定额,并填写了工序卡片。分别设计了一套钻联接孔的钻模与镗轴承孔的镗模,并进行了定位误差分析。

ABSTRACT
Crankcase is a typical box part, its role is to hold and all the parts inside the bearing to ensure the correct position between them, so that better coordination to operate and work. Split the crankcase and the bearing bore surface, the to major rough surface and hole finishing operations separately. In the development process card. Were designed a drill hole jig join bearing hole boring and boring model, and location error analysis out.
Key words: Process; cutting the amount of fixed working hours; special fixtures; positioning error analysis
