高档机床主轴自动换挡PLC控制及实现

Realization of High-Grade Spindle Automatic Shift by PLC Control

通过修改数控系统机床参数与PLC编程,实现了配套国产高档数控系统的大型五坐标双龙门铣床的自动换挡。执行换挡过程中控制主轴电机来回摆动,换挡冲击小,易于液压拨叉推动齿轮实现稳定配合,可靠性高,提高了国产数控系统在航空领域的应用水平。

By modifying the CNC machine parameters and PLC programming, the automatic shift functions of the spindle supporting the domestic high-end CNC system for large five coordinate double milling machine was realized. During the execution of shifting, the spindle motor is controlled back and forth, with small shifting shock, easy for hydraulic fork to drive gear with stability and high reliability. The application level of the domestic CNC system in aviation is improved greatly.
