起动机磁极拧紧机是在电机装配的过程中，能够将固定磁极与机壳之间的螺钉自动拧紧，并实现定扭矩的一种机器。
其应用的螺纹拧紧技术依据是扭矩控制，角度补充的方法，两者结合运用，可大大的提高对定扭矩的精度要求。基于以上理论基础，进行工艺设计。机器先实行一次快进，行至与螺钉有些的接触，使锥头的弹簧有一定的压缩量，然后由摆动缸工作进行自动认口。之后再进行二次快进，使锥头与螺钉紧密接触，达到弹簧已无压缩量，两者如此结合是防止有锥头滑出刃口的，造成刃口划伤的情况。随后油马达驱动，开始紧丝工作，直至液压系统的压力表达到设定值，下一步再由摆动缸工作，实施角度补充，进一步接近要求的扭矩值。最后各紧丝头退回原位，如果是单排螺钉的话，夹具松开，一次循环工作结束。若是多排，重复以上动作，直至达到要求为止。
整机采用PLC可编程控制，实现自动自动紧丝。

Pole starter tightening aircraft in the motor assembly process, the pole can be fixed with the chassis between the automatic screw tightening. and achieve a set torque machines. The application thread tightening technology is based on the torque control, add perspective, combining the two use can greatly improve the determination of the accuracy of torque. Based on the above theoretical basis for process design. Machines first introduce a faster progress towards the screw with some contacts so that the first cone of a certain spring compression, then swing cylinder automatic identification work mouth. After twice Fast Forward, the first cone in close contact with the screw and spring had reached compression, the two combined to prevent such a cone head slid off the edge, causing the edge of the scratch. Oil motor drive then started to bear silk work until the hydraulic system pressure gauge to set value, The next step then swing cylinder, the implementation of additional perspective
