补充资料:钻孔(扩孔与铰孔)

各种零件的孔加工,除去一部分由车、镗、铣等机床完成外,很大一部分是由钳工利用钻床和钻孔工具(钻头、扩孔钻、铰刀等)完成的。钳工加工孔的方法一般指钻孔、扩孔和铰孔。



用钻头在实体材料上加工孔叫钻孔。在钻床上钻孔时,一般情况下,钻头应同时完成两个运动;主运动,即钻头绕轴线的旋转运动(切削运动);辅助运动,即钻头沿着轴线方向对着工件的直线运动(进给运动),钻孔时,主要由于钻头结构上存在的缺点,影响加工质量,加工精度一般在IT10级以下,表面粗糙度为Ra12.5μm左右、属粗加工。



一、钻床



常用的钻床有台式钻床、立式钻床和摇臂钻床三种,手电钻也是常用的钻孔工具。



1.台式钻床



简称台钻,是一种在工作台上作用的小型钻床,其钻孔直径一般在13mm以下。



台钻型号示例:Z  4  0  1  2



                        



                                 数:最大钻孔直径
