在铣床上铣削批量较大(500～1000件)的二、三、四、六等分的工件时,如果利用分度头转动分度手柄来进行等分铣削,则需要转动分度手柄很多圈数,既麻烦,又易出差错。当利用分度头的刻度环进行直接分度时,即将蜗杆脱落手柄板下,使蜗杆、蜗轮脱离啮合,那么主轴固紧手柄由于夹紧力小,在铣削力的作用下,也易造成等分不准。为此,我们设计了铣床快速等分装置,经实际使用效果较好。简单介绍如下。
When milling a large number of workpiece (500 to 1000 pieces) in two, three, four, and six halves on a milling machine, if you use the indexing head to rotate the indexing handle to perform the bisector milling, you need to turn the indexing handle by many turns Number, both troublesome, but also easy to go wrong. When using indexing graduation ring for direct indexing, the worm will be off the handle plate, so that the worm, worm disengagement, then the spindle clamping handle due to the clamping force is small, under the action of the milling force is also likely to cause such as Not allowed. To this end, we designed a fast milling machine equalizer, the actual use of better. Brief introduction is as follows.
