在机修和机械加工中,常遇到狭小缝隙和阴蔽处无法观察的问题。现介绍一种可倾式反光镜,它对解决上述困难是非常有效的。现将结构介绍如下(参看附图):在紫铜管的内孔中套入一根用粗钢丝制成的推杆3,推杆的一端螺纹处旋入球面柄5,并在端部铆大,防止松动脱出。推杆的另一端锤扁,并钻一小孔。紫铜管的长取300mm,一端套入一个锻成球面的垫圈4,在其一边用锡焊住;另一边(头部)用铆大的方式加以固定。紫铜管的另一端锤成弯钩状,串进一根铰链轴,同时套入玻璃镜的固定框。固定框用厚0.4mm的铜皮围成,相接部分用焊锡焊牢,小玻璃镜
In mechanics and machining, often encounter small gaps and unobservable problems. A tilting mirror is presented that is very effective in solving the above difficulties. Now the structure is introduced as follows (see attached drawings): the inner hole of the copper tube into a push rod made of thick steel wire 3, one end of the push rod threaded into the spherical handle 5, and the end of the riveting Large, to prevent loosening. Hammer the other end of the hammer flat and drill a small hole. Take a long copper tube 300mm, one end into a forged spherical washer 4, on one side with a solder live; the other side (head) with riveting big way to be fixed. The other end of the red copper tube is bent into a hook shape, a hinge pin is inserted into the string, and the fixed frame of the glass mirror is nested into the frame. The fixed frame is made of 0.4mm thick copper skin, and the connecting part is soldered with a solder paste and a small glass mirror
