正弦规是利用正弦函数原理对精密角度进行间接测量或加工的一种常用的精密量具或工具 ,常用于测量内、外锥体的锥角及外锥体的大小端直径 ,也用于测量角度块的角度、孔中心线与平面之间的夹角 .正弦规实际上是通过测量长度来计算角度 ,结构简单 ,造价低廉 ,使用方便 .文章通过误差分析得出 :利用正弦规测量小角度能获得很高的精度 .
Sinusoidal gauge is the use of sine function principle of precision measurement of indirect angle or processing of a commonly used precision measuring tools or tools commonly used in measuring the cone angle of the outer cone and the outer diameter of the cone, but also for measuring the angle The angle of the block, the angle between the hole center line and the plane.The sine gauge is actually calculated by measuring the length of the angle, the structure is simple, low cost, easy to use.Through error analysis: the use of sine measurement of small angle energy Get high precision.
