我车间过去在加工螺钉的六方时,是在分度头上装一个卡盤,然后一个一个地进行铣削,生产效率很低。后经魏春易同志改进了一个铣螺钉六方的夹具,一次可以装六个螺钉,同时进行加工,使生产效率提高三倍左右。夹具的结构如图1所示。图中2是本体,上面缵有六个孔(孔的位置参 In the past, when I was working on the six sides of the screws in my workshop, I had to install a chuck on the indexing head and then mill one by one, which was inefficient. After Wei Chunyi comrades improved a hexagonal milling fixture, one can hold six screws, at the same time processing, the production efficiency increased by about three times. Fixture structure shown in Figure 1. Figure 2 is the body, there are six holes above 缵 (the location of the hole parameters
