在钻床上加工时,如果采用合适的工具,可以提高劳动生产率和产品质量。下面介绍几种钻床的实用工具,以供同志们参致:快速夹头在钻床上钻孔时,常常要用各种不同的切削工具(钻头,扩孔钻、铰刀等),并且要经过几道工序。在这种情况下,为了减少更换刀具的辅助时间,可以采用如图1的快速夹头。快速夹头的构造如图1。图中1是夹头,夹头的锥形孔中放着两个钢珠3。套圈4可以在夹头1上滑动。环2是限制套圈4的。5是可以更换的套筒。把套筒5放入夹头1中,并向下移动套圈4,钢珠3就嵌入到套
When working on a drill press, using the right tools can increase labor productivity and product quality. Here are some practical tools for drilling machines for your comrades: Quick Chuck When drilling on a drilling machine, a variety of cutting tools (drills, reamers, reamers, etc.) are often used and are to be passed Several procedures. In this case, in order to reduce the auxiliary time to change the tool, the quick chuck as shown in FIG. 1 may be used. Quick chuck structure shown in Figure 1. Figure 1 is a chuck, chuck taper hole placed two balls 3. The ferrule 4 can slide on the chuck 1. Ring 2 is to limit the ferrule 4. 5 is a changeable sleeve. Place the sleeve 5 into the chuck 1 and move the ferrule 4 downwards, inserting the ball 3 into the sleeve
