一般的轴类零件花键铣削夹具大多采用:1)鸡心夹头;2)孔定位开口卡箍;3)弹簧筒夹;4)梅花顶夹等方法之一。当轴类零件因设计要求其轴端较短且精度要求较高时,无法采用上述夹具加工花键。以前一般采用加长轴端头的长度,待铣好花键后再割去此加长部分的工艺方法,浪费不少金属材料。针对此种情况,我厂设计了如图所示夹具,经实际使用证明,可以不必加长轴端,也能加工花键。顶尖装在花键铣床主轴莫氏锥孔中起定心作用,由主轴上的拨盘带动拨杆转动,从而使被加工零件转动。夹套是整体加工完毕后用3mm片铣刀从中心处 Most of the shaft parts spline milling fixture are mostly used: 1) chicken heart chucks; 2) hole positioning opening clamp; 3) spring collet; 4) plum top folder and other methods. When the shaft parts due to the design requirements of its axial short and high precision requirements, can not use the above-mentioned fixture spline. Before the general use of the length of the shaft end of the shaft length, to be milling the spline and then cut the longer part of the process, a lot of waste of metal materials. In view of this situation, I design the factory as shown in the fixture, the actual use of that, you can not lengthen shaft end, but also processing spline. The top mounted spline milling spindle Morse taper play a central role in the spindle driven by the dial to rotate, so that the parts are processed to rotate. Jacket is the overall processing finished with 3mm film cutter from the center
