细长轴在加工制造及使用过程中,经常由于弯曲造成报废。为了达到使用要求,应进行调直。下面谈谈锤击法调直细长轴。锤击调直,主要是使受击部分的轴表面产生微小的拉应力,使之保持调直后的形状,以达到调直的目的。调直时,先找数据:按图1将轴架在V型铁上,每隔300毫米左右分出20毫米左右的一个小格,用笔画上圈(小格要选在非配合面上);把百分表打在小格中间,用手慢慢转动轴,找到最 Slender shaft in the process of manufacture and use, often scrapped due to bending. In order to meet the requirements, should be straightened. Here to talk about hammering straighten slender shaft. Hammer straightening, the main part is to be affected by the shaft surface of the tiny tensile stress, to maintain the straightened shape, in order to achieve the purpose of straightening. Straightening, the first to find the data: According to Figure 1 on the V-shaped iron shaft, separated by about 20 millimeters every about a small grid of 20 millimeters, with the pen on the circle (small grid to be selected in the non-mating surface) ; Hit the dial indicator in the middle of small cells, slowly rotate the shaft by hand to find the most
