改进前(图1):全部手动,每加工一个套圈,需四个动作若平均班产700～1000件计算,共需动作2800～4000次,工人付出体力强度很大。 改进后(图2):全部自动,效果良好,灵敏,准确,由于机械传动较勾动受力均匀,减少仪表调整时间,在加工过程中,缩短辅助时间,提高生产效率10％。 Before the improvement (Figure 1): All manual, each processing a ferrule, four movements required If the average class production of 700 to 1000 calculations, the total action required 2800 ~ 4000 times, the workers pay a great deal of physical strength. Improved (Figure 2): All automatic, effective, sensitive, accurate, due to the mechanical transmission force than the hook uniform, reducing instrument adjustment time, in the process of processing, shortening the auxiliary time and increase production efficiency of 10%.
