铣削凸轮专用夹具,是用螺栓固定在铣床工作台上的,并可调整位置,使轴14的轴线与立铣床的横方向平行。加工时把凸轮毛坯放置在定位盘3上 (附图),定位盘上有两个螺孔可将工件夹紧。调整方向,保证立铣刀5的加工距离。转动手轮13,轴14上的伞齿8与轴4上的伞齿2啮合,带动定 Milling cam special fixture, is bolted to the milling table, and can be adjusted so that the axis of the shaft 14 and horizontal milling machine horizontal parallel. When processing, the cam blank is placed on the positioning plate 3 (with photo). There are two screw holes in the positioning plate to clamp the work piece. Adjust the direction to ensure that the milling cutter 5 processing distance. Rotating the hand wheel 13, the bevel teeth 8 on the shaft 14 meshes with the bevel teeth 2 on the shaft 4 to bring about the setting
