利用正弦规测量工件角度是一种间接测量方法。测出尺寸的有关线值后,通过直角三角函数计算得到工件的角度值。正弦规在生产中应用得很普遍,而且使用也很方便。但是,当测量的角度较大(大于45°)时,垫入的块规也相应很高,致使正弦规扳起的角度很大,工件和量规体的重心偏高,稍不注意,就会使正弦规和工件发生翻转,工作很不安全。为了安全测量笨重且角度大的工件,我们
Measuring the workpiece angle using a sine gauge is an indirect method of measurement. After measuring the size of the relevant line value, through the trigonometric trigonometric function to calculate the angle value of the workpiece. Sinusoidal in the production of very common, but also easy to use. However, when the measurement angle is larger (greater than 45 °), the block gauge to be inserted is correspondingly high, resulting in a large angle of the sine gauge. The center of gravity of the workpiece and the gauge body is too high to be ignored. Turn the sine and workpieces flip, work is not safe. In order to safely measure the heavy and angle of the workpiece, we
