摘要
针对目前消声器气密性检测的水浸式检测法存在速度慢、效率低、消声器表面易产生锈蚀,影响消声器的品质等不足,开发出一款新的消声器气密检测设备。设备由机械传动、气动控制和PLC控制3大系统组成,设计时充分考虑现场使用要求,采用机、电、气一体化设计,选用三菱FX2N系列的PLC作为控制器,通过磁性传感器、压力传感器等元器件为PLC采集输入信号,再通过PLC程序控制气动元件实现汽车消声器的气密检测。设备具有手动、自动、故障报警和显示等功能,提升了设备工作效率,也方便了设备的检修和维护。
In view of the shortcomings of the current water immersion detection method for muffler air tightness detection,such as slow speed,low efficiency,easy corrosion on the surface of muffler and affecting the quality of muffler,a new muffler air tightness detection equipment is developed.The equipment consists of three systems:mechanical transmission,pneumatic control and PLC control.The design takes the field requirements into full consideration.The design adopts the integrated design of machine,electricity and gas,selects Mitsubishi FX2N series PLC as the controller,collects input signals for PLC through magnetic sensor and pressure sensor,and realizes air tightness inspection of automobile muffler by PLC programming Measurement.During the detection,the muffler air tightness detection and tooling clamping are linked to form an interlock,so that the qualified muffler can be released by the clamping mechanism,while the unqualified muffler needs a special person to open the unlocking button of the unqualified muffler with a key,so as to ensure the factory quality of the muffler.In addition,the equipment has the functions of manual,automatic,fault alarm and display,which improves the working efficiency of the equipment and facilitates the overhaul and maintenance of the equipment.
