摘　　要：针对目前机加工面定位参数检测设备检测效率低、成本高的问题,研制了基于PLC+上位机的自动检测系统。系统采用PLC+上位机的控制模式,以OPC为通讯方式,以双手按钮为控制工具,通过线性传感器、数据采集卡和上位机相结合的数据采集系统,实现了后桥扭力梁机加工面的前束角、后倾角定位参数自动检测。为了验证系统的稳定性和可重复性,提出应用重复性误差来评价,通过系统现场运行的数据分析可知,各定位参数的重复性误差Cg≥7,表明系统具有很好的重复性和稳定性,这对同类产品的开发提供了参考。At present, the testing equipment of machining surface alignment parameter is low efficiency and high cost, so this paper developed the automatic test system based on PLC ＋ PC to avoid the problem. The system realized the detection forthe surface alignment parameter of toe angle and caster angle of torsion beam rear axle by the control mode with PLC ＋ PC, OPC communication way, both hand buttons as the control tool, and the data acquisition system using the combination of the linear sensor, data acquisition card and PC. In order to verify the system stability and repeatability, repeatability error is put forward. Finally, the test experiments show that the repeatability error Cg of the alignment parameters is higher than 7, so the system has a good repeatability and stability. The research provides the reference for the development of similar products.
