摘要
抽油机曲柄齿专用铣床由HG50/1250分齿工作台、HJ40/400进给机械滑台、TX25A铣削动力头、专用自动分齿机构和定位支承部分组成。铣齿自动操作,工效相当普通机床的3倍,且能满足加工各类高度尺寸曲柄的需要。加工时,经计算和试车优选主轴转速为630r/min,铣刀切削速度为50m/min,进刀速度77mm/min。
This paper is an introduction to the special pumping unitscrank gear milling machine, which consists of a HG50/1250indexing table, a HJ40/400 feed sliding table, a TX 25A millingpower unit, a special automatic indexing mechanism, and apositioning and supporting mechainism. It can conduct auto-matic milling operation with an efficency three times morethan a general milling machine. The mainshaft speed is 630r/minmilling cutter speed 50m/min, feeding speed 77mm/min.
