在内燃机制造中,缸体内孔检测是很重要的环节,一般采用目测的方法检查,其缺点是,效率低,容易产生漏检现象,为此,我们根据光的反射定律和平面镜成象原理,利用三块平面镜组成的光学系统就能简单、省力的进行准确检测。具体设计如图所示。若取其缸体内孔纵剖面的一条线AB进行研究时,在缸体下方放一光源,上部倾斜放置一平面镜。为使该镜反
In the manufacture of internal combustion engine, the cylinder bore detection is a very important part of the general visual inspection method, the disadvantage is that low efficiency, easy to produce missed inspection phenomenon, for which we based on the law of light reflection and mirror imaging principle , The use of optical system consisting of three plane mirror can be simple and easy to carry out accurate detection. Specific design as shown. If taking a line AB of the longitudinal section of the bore of the cylinder body for research, a light source is placed under the cylinder body, and a flat mirror is placed obliquely on the upper part. To make the mirror negative
