摘　　要：针对飞机大梁加工专用数控机床的摆架使用性能、机床的结构,摆架部分完全可以看作是刚性体,根据正弦尺测量原理,可把正弦尺和合像水平仪放在摆架顶面上,所测量的角度即为摆架旋转的角度。结合定位精度的检测方法,给出了摆架定位精度的合理的检测手段,为以后同类机床的检测提供了理论依据。In view of the airplane summer beam processing special-purpose numerical control engine bed rocket frame operational performance, the engine bed structure, the rocket frame part definitely may regard as is a rigid body, according to the sine bar survey principle, may and gathers the sine bar the horizon to place likely on the rocket frame top, surveys angle namely for rocket frame revolving angle. The union pointing accuracy examination method, has given the rocket frame pointing accuracy reasonable examination method, has provided the theory basis for later similar engine bed examination
