本文介绍一种应用自准仪测量6L207E型柴油机机体上下主轴承孔不平行度和气缸孔对主轴承孔不垂直度的新方法。不同心度和不平行度新测量方法的长期使用和不垂直度多次试测的结果表明,新测量方法减小和避免了温度和量具挠度对测量结果的影响,提高了测量精度,使测量方法误差控制在被检参数允差的1/5以内,从而使测量变得完全可靠,效率比原机械
In this paper, a new method for measuring the non-parallelism of the upper and lower main bearing holes of the 6L207E diesel engine body and the non-perpendicularity of the cylinder bore to the main bearing bore is introduced by using the self-collimation instrument. Long-term use and non-perpendicularity of new measurement methods with different concentricity and non-parallelities The results of multiple tests show that the new measurement method reduces and avoids the influence of temperature and measuring deflection on the measurement results, improves the measurement accuracy, Method error control in the seized parameters within the tolerance of less than 1/5, so that measurement becomes completely reliable, the efficiency of the original machinery
