摘　　要：对研制新型振动攻丝机的必要性进行了分析,确定了新型振动攻丝机的功能要求。研制的新型振动攻丝机采用了机械式激振器,主轴既作回转运动也产生振动;在主轴上设有螺纹,由两个步进电机分别控制主轴螺杆和螺母转动,可以合成要求的螺距,实现了通用靠模的功能;能同时实现周向振动和轴向振动;控制系统采用了主、副控制器结构。该机经试验达到设计要求,对于振动挤压攻丝有较好的效果。In this paper,the necessity of developing a new vibration tapping machine was analyzed.The function of the new vibration tapping machine was identified.Because of using mechanical actuator,the spindle moves in rotation and vibration.A universal function of mode was implemented by using two stepper motors to control the the rotation axis screw and nut on the spindle with thread.Vibration on the peripheral direction and the axial direction was realized.The control system uses the structure of master-deputy controlle.The test has proved that the machine meets the design requirements,and it has a good effect on vibration tapping extrusion processing mode.
