气门作为发动机的关键零部件,对其尺寸公差和形位公差要求较高.针对传统手工检测方法存在检测效率低、精度不高的缺点,本文提出由工业控制计算机(IPC)和Mahr C1208电感测微仪构成的主从式气门杆端面跳动误差测量系统.Mahr C1208电感测微仪负责完成气门杆端面跳动误差测量;IPC负责完成系统参数设置、数据处理以及报表生成;采用图形化编程语言LabVIEW完成上位机控制软件设计.实验结果表明该系统的操作简单、效率高、扩展性好.%The dimensional tolerance and geometric tolerance of valve, which is the key component of the engine, are of great importance. Since the traditional manual detection method is inefficient and the accuracy of which is low, the master-slave valve stem run-out error measurement system, consists of IPC and inductive sensor (Mahr C1208), is designed in this paper. Inductance sensor is responsible to the investigation of the stem run-out error, while IPC accomplishes the setting of parameters, data processing and reports output. Besides, the PC control software is designed by LabVIEW (NI Corporation, USA), a graphical programming language. The result of experiments on the test platform show that this software is easy to operate, effective and extensible.
