深孔内抛物面数控镗刀设计

The Design on CNC Boring Tool of Inner Paraboloid in Deep Holes

根据深孔内抛物面底孔的尺寸要求,设计了深孔内抛物面镗刀的整体结构,介绍了实现深孔内抛物面加工的机械结构。总体上由数控镗刀装置组成,交流伺服电机通过减速装置控制进给量,菱形刀片一边以镗刀装置的销轴做圆周运动,工件一边也在做回转运动,再配合镗杆的轴向运动,数控系统通过插补软件包控制数控镗刀装置做有规律的抛物线运动,两轴联动就加工出了深孔内抛物面,值得在全国推广使用。

According to the size requirements of the inner paraboloid underport in deep holes,the overall structure of the inner paraboloid boring tool in deep holes was designed,and the mechanical structure for machining the inner paraboloid in deep holes was introduced.Generally,it is composed of a CNC boring tool device.The AC servo motor controls the feed rate through the deceleration device.While the diamond shaped blade is making Circular motion with the pin axis of the boring tool device,the workpiece is also making a rotary movement,and then it cooperates with the axial movement of the boring bar.The CNC system controls the CNC boring tool device to make regular parabolic movement through the interpolation software package.The inner paraboloid in the deep hole is processed through the linkage of two axes,which is worth popularizing nationwide.
