90°V型块是工厂里用来支承圆柱形工件常用的工具。各种宽度V型块(附图)的最大支承范围可用下式计算:D=1.414W,式中D:最大支承直径;W为V型槽顶宽。反之,W=0.7071D此式可用来计算支承某预定直径工件的V型块最小槽宽,也可根据V型块的槽宽来计算工件的最大直径。
The 90 ° V block is commonly used in the factory to support cylindrical workpieces. The maximum support range for various width V-blocks (with photos) is calculated using the following formula: D = 1.414 W where D: maximum support diameter; W is the V-groove top width. On the contrary, W = 0.7071D This formula can be used to calculate the minimum width of the V-shaped block supporting a workpiece of a predetermined diameter. The maximum diameter of the workpiece can also be calculated based on the width of the V-shaped block.
