宜昌市电机厂在生产发电机总装过程中,感到要拧紧磁极螺钉工作量很重,每台60千瓦发电机转子中M18的螺钉就有32个,工人同志为了摆脱繁重的劳动,动脑筋,搞革新,自己制造了一台电动拧螺钉机,经过三个多月的使用证明效果很好。拧螺钉机的工作特点简介如下拧螺钉机的电气原理图如图1 拧螺钉机的机械传动示意图如图2 Yichang City Motor Factory assembly process in the production of generators, felt the need to tighten the magnetic screw heavy workload, each 60 kilowatts generator rotor M18 screw there are 32 workers in order to get rid of the heavy labor, brains, engage in Innovation, made their own electric screwdriver, after more than three months of use proved to be very good. Screw screw machine features brief introduction as follows Screw screw machine electrical schematic diagram shown in Figure 1 Screw screw machine mechanical transmission diagram shown in Figure 2
