在机械修配时,孔经常需要去锈和修磨。在没有酸洗的条件下,采用手工去锈和打磨很费力,特别是对于孔径在φ150mm以下较深的孔,手工打磨和去锈更加困难。在工作实践中我们设计了如图所示的工具、解决了上述问题。 该工具为台阶轴,小径部分为柄部,夹持在手电钻上。大径端沿轴向开有1—1.5mm宽的长槽。使用 In mechanical repair, holes often need to go rust and grinding. In the absence of pickling conditions, the use of manual rust and grinding is laborious, especially for the hole diameter of φ150mm deep hole, manual grinding and rust more difficult. In the working practice we designed the tools shown in the figure to solve the above problems. The tool for the step axis, the small diameter part of the handle, clamped in the hand drill. Large diameter end along the axial opening 1-1.5mm wide slot. use
