瞄准定位的形式基本上可归纳为接触式和非接触式两类。这里讨论的是利用被测零件的刻线或几何图形来实现合线或合线套合瞄准定位的一种方法。一、瞄准原理这种方法,是通过棱镜组来实现的。主要原理是利用被瞄准的本身(如刻线)产生两个半影像,然后使两个半影像在分开的断面处彼此重合形成一个完整的影像,从而得到了合线或合线套合的瞄准定位形式。棱镜组的结构很简单(如图1所示),它由三块形状相同的
Targeted positioning can basically be summarized in the form of contact and non-contact type. Discussed here is the use of the measured part of the engraved lines or geometry to achieve co-line or co-aiming alignment method. First, the principle of aiming this method is achieved through the prism group. The main principle is to use the target itself (such as reticle) to produce two semi-images, and then make the two half-images at separate sections coincide with each other to form a complete image, resulting in the alignment of a wire or wire Positioning form. The structure of the prism group is very simple (Figure 1), which consists of three identical shape
