我厂主要生产1～5号小型三相异步电动机;过去,我们对JO_21～3号每一个机座号,都设计制作一套铣机座底脚平面夹具,共做三套。使用时,每换一个机座号的机座,就得换一次夹具,比较麻烦,增加了拆卸、安装、校正等辅助工时。后来,我们在设计C系列电动机的机座底脚平面夹具时,改为在一套夹具的止口盘上开三个止口,将C80、 I plant mainly produces 1 to 5 small three-phase asynchronous motor; in the past, we JO_21 ~ 3 for each frame number, design and manufacture of a set of milling machine feet at the end of the plane fixture, a total of three sets. Use, each for a frame size of the base, you have to change the fixture, more trouble, an increase of demolition, installation, calibration and other auxiliary working hours. Later, we designed C-series motors at the foot of the plane when the fixture, instead of a fixture in the mouth plate to open three stop, the C80,
