在修复镗杆副时,需更换空心主轴中的钢套。由于钢套内径是85mm,而空心主轴左端的内径只有87mm,拆卸面积太小。而且,还要保证空心主轴孔完好无损。为此,我们设计了一套简易的拆卸钢套工具。拆卸钢套的简易工具结构如图1,它是由导向套、拉套、重锤、拉杆组成。首先将空心主轴固定,再把A、B两个半圆拉套 When repairing the boring bar pair, replace the steel sleeve in the hollow spindle. Since the inner diameter of the steel sleeve is 85mm, and the inner diameter of the left end of the hollow main shaft is only 87mm, the removal area is too small. Also, make sure that the hollow spindle hole remains intact. To this end, we have designed a set of easy dismantling steel sleeve tools. Removable steel sleeve simple tool structure shown in Figure 1, which is the guide sleeve, sleeve, hammer, rod composition. First hollow mandrel fixed, then A, B two semicircular pull sets
