活动螺撑帽是前进型蒸汽机车上的一种零件,每台机车上需要1300多个,生产批量较大,在通用机床上加工,劳动强度大、效率低,成为生产中的一个关键。我厂附件车间职工在技术革新活动中,。自行设计、建成了一条活动螺撑帽加工自动线,经过两年多的实际运用,效果良好,生产效率提高20％,并显著地减轻了工人的劳动强度。该自动线由粗加工、精加工车床各一台和输送装置组成。本文介绍自动线上的精加工自动车床。 Activity screw cap is a forward steam locomotive a part, each locomotive needs more than 1300, a large production volume, processing in a common machine tool, labor-intensive, low efficiency, become a key production. I plant attachment workshop staff in technological innovation activities. Designed and built an automatic screw cap processing automatic line, after more than two years of practical application, the effect is good, the production efficiency increased by 20%, and significantly reduced the labor intensity of workers. The automatic line by the roughing, finishing lathe each one and the delivery device. This article describes automatic online finishing automatic lathes.
