发动机缸体挺杆孔加工工艺分析

摘要

This article analysis the constructive features and technical indicators of engine cylinder tappet hole, introduce the variety of the processing technology in motor enterprises by now. And discuss the weak-ness of traditional process, which has low precision, poor chip removal and cooling and fixture complex. Base on the actual situation of mass production in motor enterprises, issue out gun drill &reaming applica-tion with high efficiency and precision, present valuable working process parameters. Also it can be a cer-tain reference value for other cylinder hole making.%文章通过分析发动机缸体挺杆孔的结构特点和技术指标，介绍了现在汽车企业所使用的多种加工工艺方法。论述了传统加工工艺方法存在的加工精度低、排屑和散热差、夹具复杂等方面的不足。结合目前汽车企业大批量生产的实际情况，提出了高效率、高精度的枪钻—枪铰加工方法及加工条件，并给出了具有实用价值的工艺参数。同时对其他缸体孔加工有一定的参考价值。
