深小槽和较大内圆孤工件的测量,是常遇到的检测工作之一。以往一般采用通用量具和附加设备来进行,但都较为麻烦,而且准确性较差,特别是底部是小圆孤形状的深小槽工件就更是如此了。针对上述问题,我们将普通的深度尺,进行了改革,改革后的深度尺称为特种深度尺。改革后的深度尺(结构原理见图1),增大了使用范围,提高了在使用时的稳定性。因测量杆细小端头是呈圆弧形的,所以对底部为圆弧形的不同阶梯的深
Deep groove and the larger inner circle of the workpiece measurement, is often encountered in the detection of work. In the past the general use of universal measuring tools and additional equipment to carry out, but are more troublesome, but less accurate, especially the bottom is a small round shape of the deep groove work-piece even more so. In response to the above problems, we will be a common depth scale, the reform, the depth of the reform of the scale known as the special depth scale. After the reform of the depth of foot (the principle of the structure shown in Figure 1), increasing the scope of use and improve the stability of the use of. Due to the small end of the measuring rod is arc-shaped, so the arc-shaped bottom of the different steps of the deep
