摘要
异型螺杆零件具有螺距和底径随角度变化的特点,在通用数控车、铣床上难以实现加工。本文设计了一种新型长杆异型螺杆专用数控铣床,应用FANUC0i-MC数控系统;采用卧式铣床结构,由c轴带动工件旋转,x轴和z轴交流伺服电机驱动实现切削进给,铣刀主轴采用交流变频无级调速,数控螺杆铣床三轴三联动。研究表明,该成果对提高加工异型螺杆的生产效率和加工质量,拓展数控铣床的功能,具有广泛的实际工程意义。
The special shaped spiral rod can not be machined on a universal CNC lathe or a milling machine because its pitch and the bottom diameter vary with the angle. In this paper, a new type special CNC milling machine for processing long special shaped spiral rod is designed with the FANUC 0i-MC CNC system with the horizontal structure. The CNC milling machine is of three-axis linkage. The rotation of the workpiece is driven by axis c, and the milling feed is provided by the Alternating Current （AC） servo motor on the axes x and z. The AC frequency conversion stepless adjustment is adopted to control the rotation speed of the milling spindle. It is shown that the new machine has a wide range of practical engineering applications in view of improving the productivity and machining quality for processing special shaped spiral rod, and extending the functions of CNC milling machines.
