摘　　要：针对轮毂轴承铆接加工过程中存在的微调不方便、加工精度不高等问题,基于闭环控制原理,设计研究了一种可编程序控制器和伺服电机控制进给位移的新型旋铆机。该旋铆机的升降装置采用了大功率伺服电机、行星减速机和重型滚珠丝杠驱动,外加光栅尺构成了闭环控制;检测装置采用了精密级高度计作为检测传感器检测实际毛坯高度和加工后成品的高度;通过在工件夹具下方装设轮辐称重传感器以实时反馈旋铆加工时的工作压力。实践结果表明,该旋铆机实现了加工坐标值自动调整和毛坯材料性能的自动检测,从而实现了轮毂轴承零游隙和负游隙的控制,同时降低了轮毂轴承的各零件制造精度要求。Aiming at the problem of the inconvenient fine adjustment and the low machining accuracy in the riveting process of wheel hub bearing,based on the theory of closed-loop control,a new intelligent riveting machine was designed and studied,of which the feed displacement was controlled by a programmable logic controller and a servo motor. The lifting device of the riveting machine closed-loop controlled by raster ruler was driven by a high power servo motor,a planetary reducer and a heavy-duty ballscrew; In the detection device,a precision altimeter was adopted as a detection sensor to measure the height of blank and the height of finished product after machining; the spoke weighing sensor was mounted below the fixture,which can real-time feedback working pressure when riveting processing. Production practice results indicate that,this intelligent riveting machine can realize the control of the zero or negative clearance of wheel hub bearing,and the machining precision for each component of wheel hub bearing can be reduced with the adoption of this intelligent riveting machine.
