电机壳加工专用数控机床的设计
摘要
对于特定的电动机的外壳壳体内孔、止口的加工，设计电机壳体专用的数控立式车床的主轴箱。电机被广泛应用于各种机械与机床设备的传动上。定子与转子之间的气隙大小会直接影响电机的性能,而其气隙大小由电动机壳体铁芯孔与两端面的止口的同轴度来决定。设计内容包括根据所给出的额定转速下的工作状况的切削功率，选用适当的电动机，提高主运动的电动机使用率；主轴箱部分部件的设计；箱体的设计；其中最主要是主轴中采用了双列圆柱滚子轴承（锥孔），比其他轴承的回转精度更高，提高了被加工零件的圆度、圆柱度、跳动等精度；以及皮带机传动中采用球型垫片来实现张紧功能。

The design of special-purpose NCN machine tool for machining the shell of electric machine
Abstract
To design the spindle box of special-purpose NCNvertical lathe for machining holes,seam allowance and end face of the shell of electric machine. The motor iswidely used in the transmission ofvarious kinds of machinery and Machine tool equipment. The size of the air gap between stator and rotor can directly affects the performance of the motor，and is determined by the coaxial degree of the motor casing and the seam allowances of the ends.the contents of design include: According to the cutting power of the combined operating mode, to choose the suitable motor to improve the main drive motor utilization;the design of box; The design of a specialworkbench for special fixtures. The key of the design is that spindle bearing is usedwith double column roller bearing(conical hole), ofwhich rotationprecision is higher than other bearings,to improve the circulardegree, cylindricity,beat accuracy and etc.Aswell as，Ball spacer is used in belt drive to implementation the tensioning function
Keywords: The shell of electric machine；Special CNCvertical car；The spindle box
