飞机结构件多工位柔性夹具设计

摘要

针对飞机长梁类零件的数控铣削加工,提出一种柔性、快速、多工位夹具方案.详细论述了柔性系统的机构组成、工作原理及PLC控制系统.采用支撑板与挡板定位,气动增力机构夹紧,利用PLC控制器,实现传感器感知、工件自动定位与夹紧,并编制了相应控制程序且调试成功,为飞机结构件柔性多工位夹具系统在数控加工中的应用提供参考.%For the NC milling of aircraft girder parts,a plan for flexible,fast and multi-station clamping fixture is proposed.The mechanism composition,working principle and PLC control system of the flexible system are discussed in detail.Using the support plate and the baffle for positioning and pneumatic boosting mechanism is used to clamp.Sensor sensing,automatic positioning and clamping of workpiece is implemented by utilizing PLC controller.The corresponding control program is worked out and debugging success.The reference is provided for the application of multi-station flexible fixture system of aircraft structural parts in NC machining.
