可限位钻、扩孔器设计

Design of an Adjustable Reamer

介绍了一种新型钻、扩孔限位器的设计方案,配套在钻床上,适用于对孔深度要求高的工件钻孔、扩孔和攻丝。详细描述了该种专用限位器的工作原理和结构特征。该限位器不仅能满足孔深度加工的尺寸精度,而且还提高了生产效率。同时对结构相似的零件加工具有较大的研究参考价值。

In the paper, a new type of reamer installed on drilling machine is introduced, which is suitable for drilling, reaming and tapping parts with very high accuracy requirements. Operating principles and structural characteristics a,e described. This reamer can meet the dimensional accuracy requirements, and enhance production efficiency. Meanwhile, for the machining of components with similar structure, it has significant reference value.
