摘要
针对某发动机缸体曲轴孔的精加工精度要求,通过分析其加工难点,选择了镗削加工作为曲轴孔的精加工方法,并确定了刀具材料、加工冷却和排屑方式以及镗削时各项切削参数,制订了曲轴孔精加工时的定位和夹紧方案。通过机床实物制造,对工件进行了试切。经检测,曲轴孔各项精度指标均达到或超过设计要求,成功地在重庆某机械制造企业投产。
This paper aiming to finishing precision of crankshaft hole of an engine cylinder,selects method of boring as the crankshaft hole finishing by analyzing its processing difficult.And it determined the tool material and form,method of processing cooling and chip clearance.This paper formulated the scheme of crankshaft hole finishing＇ s positioning and clamping,and determined the boring＇ s cutting parameters.Finally the cylinder is trial cut through the manufacture of the machine tool.The precision indicators of crankshaft hole reach or exceed the design requirements after tested,and it is put into a Chongqing machine manufacture enterprise successfully.
