榨油机榨螺加工专用的旋风铣及其控制系统设计

Design of control system for external thread whirling machine used for processing pressing screw

设计一种外螺纹旋风铣及其控制系统,以PLC为主控制器,触摸屏为人机界面,伺服电机和交流电机为执行机构,通过参数设定,对不同规格的榨油机榨螺进行加工。该系统与传统加工方法相比旋风铣削加工榨螺可一次成型,与原机床旋风铣削相比不需要调整靠模板、降低了对操作工的技能要求、排除了人为误差使得进刀角度更为精确。

An automatic control system for the external thread whirling machine which is designed, with PLC as master controller and touch screen as human machine interface, using servo motor and AC motor as actuator, achieves automatic processing for different specifi cations pressing screw by setting different parameters. The control system can be a one-shot forming by thread whirling compared with traditional processing methods and does not require adjustment for master plate compared with the original external thread whirling ma chine, thus significantly reducing the operator＇s skill requirements, eliminating human error makes knife angle more accurate.
