在机械加工中。常常感到对斜面、斜孔及异形样板的测量比较困难。我们利用正弦规原理,制造了正弦方箱体,通过座标旋转,可在平台上用千分表测量,既准确。又方便。正弦方箱由三部分组成:方箱体、正弦棒和夹紧装置,如图1所示。方箱体精度要求较高,它的一面用于安装被测工件,其他五个平面都安有正弦梓,这样其它五个面可起正弦规作用。正弦棒10用 In machining. It is often felt that it is more difficult to measure bevels, slant holes, and shaped patterns. We use the principle of sine gauge, the manufacture of the sine square box, through the coordinate rotation, you can use the dial gauge on the platform to measure, both accurate. And convenient. Sine square box consists of three parts: square box, sinusoidal rods and clamping devices, as shown in Figure 1. Square box requires high precision, one side for the installation of the workpiece under test, the other five planes are Sinus azusa, so that the other five can play a sine function. Sinusoid 10 used
