大型宽底座角尺的长边工作面的宽度一般制造成6毫米左右。本文提出一种检定方法,仅供参考。将被检大型宽底座角尺如图1平放在平板上。此时,在角尺的短边的适当的位置上用二只弓型夹子把角尺固紧在平板上。然后,在角尺的长边的最合适的支承点上用图2所示的支承装置来支承。再将平面度检查仪的反射镜用螺钉固紧在靠柱(见图3)的上平面上。使靠柱和角尺的长边工作面相
The width of the long side face of a large wide base is usually made to about 6 mm. This article presents a test method, for reference purposes only. Will be seized large wide base angle square as shown in Figure 1 flat on the flat. At this point, use two bow clamps to secure the square to the plate in place on the short side of the square. Then, it is supported by the supporting device shown in FIG. 2 at the most suitable supporting point of the longer side of the square. Then flatness tester reflector screwed on the column (see Figure 3) on the plane. So by the column and the long edge of the square face phase
