在种类繁多的金属切削工具中,带扁和方尾的占有相当大比例,其加工一般在铣床上进行。为此,我们设计了一种加工扁和方尾的铣床夹具,如图所示。 1.夹具工作原理 该夹具由三部分组成,一是联接部分,主体16的柄部为莫氏4号锥度与分度头主轴相配。二是夹紧部分,工作时顶尖22顶在被夹紧工件的中心孔上,拧紧翼形螺母5,通过上、下卡爪 In a wide range of metal cutting tools, with flat and square possession of a large proportion, the processing is generally carried out in the milling machine. To this end, we have designed a milling machine flat and square tail milling fixture, as shown. 1. Fixture working principle The fixture consists of three parts, one is the connection part, the handle of the main body 16 is Mohs 4 taper and indexing spindle. Second, the clamping part of the work top 22 at the center of the workpiece is clamped in the hole, tighten the wing nut 5, through the upper and lower jaw
