孔系加工在生产实践中的应用

A Series of Hole Processing in Production Practice Application

柴油机机体是柴油机构造的主体,是安装柴油机所有零部件和附件的支撑骨架,机体凸轮轴孔内装有凸轮轴轴套,配气凸轮轴与轴套相配合贯穿整个机体,凸轮轴孔作为机体加工的重要孔系,保证着凸轮轴运转精度及整个气门驱动机构发挥正常功用。此次探讨为解决6190型柴油机机体凸轮轴轴孔同轴度超差问题和垂直油孔侧透问题,该机体的孔及孔系加工质量,对保证产品精度起着重要作用,通过此次应用对加工过程进行了有效控制。

Diesel engine＇s cylinder block is the diesel engine structure main body, the cam shaft hole takes cylinder block processing the important hole department, is guaranteeing the cam shaft revolution precision and the entire tire valve driving mechanism display normal function. This discussion is to solve 6190 diesel engine cylinder block cam shaft hole proper alignment out-of-tolerance problem and the vertical oil hole side passes the question, this cylinder block＇ s hole and a series of hole＇ s processing quality, to guarantee that the product precision is playing the influential role, has carried on the active control through this application to the processing process.
