“机械工人”(冷加工)57年11期介绍了“铣齿条的工具”一文。这篇文章主要是解决了长齿条在臥式铣床上加工的困难。这里再介绍一种在臥式铣床上加工长齿条用的附加分度装置。这个装置的特点是:1)两个齿轮固定,不必挂交换齿轮;2)计算比较方便,能够达到一定的精确度(达0.01公厘);3)手柄摇转比较方便;4)刻比较精密的刻线也可应用;5)结构比较简单。分度装置的结构如附图所示。1是铣床工作台。分度装置本体用螺钉 “Mechanic” (Cold Working) 57, Issue 11 presents the article “Tools for Milling Racks.” This article is mainly to solve the long rack in the horizontal milling machine processing difficulties. Here again introduce an additional indexing device for processing long racks on a horizontal milling machine. The device is characterized by: 1) two gears fixed, do not have to swap gears; 2) more convenient to calculate, to achieve a certain accuracy (up to 0.01 mm); 3) handle swing more convenient; 4) engraved more sophisticated The engraving can also be applied; 5) the structure is relatively simple. The structure of the indexing device is shown in the attached drawing. 1 is a milling machine table. Indexing device body with screws
