摘要
缸筒内止口同轴度超差会影响液压缸的工作性能．针对缸筒加工中造成同轴度超差的原因是定位基准与工序基准不重合和普通中心架定位调整不精确，提出了保证缸筒加工中同轴度超差的控制措施：改进装夹方式和控制中心架窝的尺寸公差带．此方法对其他筒套类零件的加工具有参考价值．
Over range error of coaxality degree of internal groove of cylinder will weaken the working performance of hydraulic cylinder.As over range error is caused by uncoincidence between locating reference and procedure reference,a control measure is put forward in order to deduce the over range error—improving the locating way and controlling the dimensional tolerance of centre frame.This measure also has reference value in the processing of other barrel\|type parts.
