我厂生产的FA801A型摇纺机有十几种调换齿轮,其模数为1.5,厚度均为8mm。在车削此类工件端面时,由于卡盘三爪长于工件,装夹时工件没有基准面依靠,调头车端面时难以保证其平行度,我们采用如图所示Y形端面定位平行垫块,效果良好。 Y形垫块采用三块尺寸一致的冷轧薄板三等分均布后焊接起来,然后在平面磨床上将两端面磨平后即可使用。操作时,先将Y形垫块端面贴平卡盘,工件 FA801A Shaft Weaving Machine produced by our factory has more than ten kinds of replacement gears with a modulus of 1.5 and a thickness of 8mm. In the turning of such workpiece end face, as the jaw three jaws longer than the workpiece, the workpiece clamping no reference surface, the head alignment is difficult to ensure its parallelism, we use the Y-shaped end face as shown in the parallel positioning pad, the effect good. Y-shaped pad using three uniform size of the cold-rolled sheet after the third uniform welded together, and then polished on both sides of the surface grinder can be used. Operation, the first Y-shaped pad end face flat chuck, the workpiece
