大直径圆周均布孔加工方法的研究

Study on processing method of uniform holes on large-diameter circumference

针对大直径销轮圆周均布孔加工困难的问题,介绍了一种偏心钻套误差补偿的加工方法,通过事先分段划线、分段加工,调整钻模相邻孔中心距的方法,在孔加工过程中逐渐消除积累误差,确保相邻孔的中心距符合要求,有效地解决了大直径销轮圆周均布孔的加工难题,并取得了良好的经济效益。

In view of the difficulty in processing the uniform holes on circumference of the large-diameter pin wheel, the paper introduced a kind of processing method to compensate the error of the eccentric drill sleeve. After sectional lining and processing in advance, the central distance of adjacent holes of the drill plate was adjusted so as to gradually eliminate the accumulative error during processing course, thus the central distance of adjacent holes was guaranteed. Therefore, the difficulty in processing the uniform holes on circumference of the large-diameter pin wheel was solved, and excellent economic efficiency was obtained.
