我厂工具车间在磨削片铣刀的安装孔时,以前是在车床上,用弹性夹圈包住外圆,用三爪卡盘夹住,再进行车削和磨削。这种方法的生产率很低。后来经工人同志门建议,采用如附图的工具,不但提高了生产效率,而且还保证了产品质量。这个工具是由胎棒1、锥柄2和外套3组成的。在锥柄2上车有阳螺纹跟外套3的阴螺纹相配合,同时还钻有内孔跟胎棒1配合。胎棒1跟锥柄2配合时,必须保持同心。工作时,把胎棒1插入锥柄2的孔内,把
I plant tool shop in the milling cutter mounting holes, the former is in the lathe, with a flexible clamp wrap the outer circle, with a three-jaw chuck grip, and then turning and grinding. The productivity of this method is low. Later by the gay door workers suggested that the use of tools as shown in the accompanying drawings, not only improve production efficiency, but also ensure product quality. This tool consists of a tire 1, a taper 2 and a jacket 3. On the taper shank 2, there is a male thread mating with the female thread of the outer sleeve 3, and at the same time, an inner hole is drilled to cooperate with the tire bar 1. The tire 1 must be concentric with the taper shank 2. Work, the tire 1 into the hole taper shank 2, put
