2118型钻床采用气动转位夹具以后,大大缩短了加工时间。加工时,一边装料,一边钻孔,钻完孔后自动转位,并把零件自动顶出。现在的加工方法比过去提高效率两倍,并且减轻了体力劳动。2118型钻床上用的气动转位夹具,如附图所示。它的工作原理,可以由以下几方面来说明:1.主轴的运动:钻床开动后,凸轮1转动,使固定在主轴上的杠杆2上下移动,这样就实现了钻床的工作
2118 drilling machine with pneumatic indexing fixture, greatly reducing the processing time. Processing, while loading, while drilling, drilling hole automatically indexed, and the parts automatically top out. The current method of processing is twice as efficient as it used to in the past and alleviates manual labor. 2118 drilling machine pneumatic translocation fixture, as shown in the figure. Its working principle can be explained by the following aspects: 1. Spindle movement: After the drilling machine starts, the cam 1 rotates, so that the lever 2 fixed on the spindle moves up and down, thus realizing the work of the drilling machine
