汽车发动机凸轮轴(如图),材料45钢,要求变形0.10毫米以下,经高频表面淬火后变形较大,有时达1毫米以上。由于凸轮轴较长和形状复杂,要求变形范围又小,校直困难、效率低。我厂热处理车间老工人经过反复摸索认真总结经验,找到了较好的校直方法,从而提高了校直效率,其方法如下: 把凸轮轴放在顶尖架上,用百分表由任意一头开始测量其全长A、B、

Automobile engine camshaft (pictured), material 45 steel, deformation of 0.10 mm or less, after the high-frequency surface hardening large deformation, and sometimes up to 1 mm above. Due to the long camshaft and complex shape, requiring a small deformation range, straightening difficulties, low efficiency. Our factory heat treatment workshop veteran after repeated exploration carefully summed up the experience, to find a better straightening method, thereby enhancing the straightening efficiency, the method is as follows: the camshaft on the top shelf, with dial indicator starting from either end Measuring its full length A, B,
