箱体零件上两同轴孔轴线之间的平行度,垂直度,平面对孔轴线的垂直度的测量,有多种检测方案。因各厂家条件不同,所使用的仪器、检具在形式上存有差别。本文结合我厂大批量生产的195型柴油机上关键零件机体的上述各项的测量,介绍一种精确度高、综合性强、且又简单易行的检测方法(图1)。 Box parts on the axis of the coaxial axis between the two parallelism, verticality, the plane perpendicular to the hole axis measurement, there are a variety of detection programs. Due to the different conditions of the manufacturers, the instruments used, gages in the form of differences. Based on the above measurement of the key parts of the 195 diesel engine in mass production in our factory, this paper introduces a high accuracy, comprehensive and simple detection method (Figure 1).
