批量生产2、3、4、5、6等分零件时,用分度头分度效率低、易出错。所以,我们改进了分度头,增添了支架和心轴等四个零件(图1),再利用分度头原有分度板,就可改成直接分度装置(图2)。图1中的心轴3与分度头主轴紧固为一体,分度手柄摇一圈,分度头主轴旋转360°。直接分度的方法:若工件需六等分,则在分度板上选择一圈孔数为6的整倍数的孔圈,例如30孔一圈。每次分度时手柄插销只要在30孔一圈 Mass production of 2,3,4,5,6 aliquots, sub-indexing with low efficiency, error-prone. Therefore, we improved the indexing head, adding four parts such as bracket and mandrel (Figure 1), and then using the indexing head original indexing board, can be changed to direct indexing device (Figure 2). The spindle 3 in FIG. 1 is fastened with the indexing spindle, the indexing handle is shaken, and the indexing spindle is rotated by 360 °. Direct indexing method: If the workpiece to be six points, then select a circle in the index plate hole integer multiples of 6 holes, such as 30 holes in a circle. Each indexing handle plug as long as 30 holes in a circle
