有时做皮带盘等铸件要用车板来造型,当挖做皮带盘档子时,须经准确分线后才能做;但很多操作同志不能准确算出,也不容易量准确,所以这工作又麻烦,又不易做好。现有一种简单分线量具供给大家试用。量具的形状见图1,在量具内圆刻上不同分线,从基线开始分起;外圆可刻上公制尺度(只能作参考,恐怕不太准确 )。制造材料可用较薄铅片,究竟多少厚度要根据具体
Sometimes do cast belt disc and other castings to use car plate to shape, when digging the belt tray file, to be accurate after the line can be done; but many operating comrades can not be accurately calculated, nor accurate, so this work is troublesome, Not easy to do well. There is a simple line of measurement available for everyone to try. The shape of the gage is shown in Figure 1, with different sub-divisions on the inner circle of the gage, starting from the baseline; the outer circle can be engraved with a metric scale (only for reference, probably not very accurate). The material used to make thin lead film, how much the thickness to be specific
