近年来,在内外圆磨床的制造与修理中,采用检验桥板与水平仪结合方法来测量床身导轨的不平行度,这种桥板属随机来的不可调普通桥板,给制造和修理带来很大不便。前几年,我厂自行设计了一种可调检验桥板,能在多种磨床上使用,效果较好。可调检验桥板的结构如图所示。结构比较简单,主要由桥板体5、导向芯轴7和调整螺钉3等零件组成。桥板体上有两条互相平行的90°V形槽,分别镶有两根导向芯轴7。两芯轴互相平行,其不平行度小
In recent years, in the manufacture and repair of internal and external grinders, the method of testing the bridge and the level of the method to measure the non-parallelism of the bed rails, this bridge is a random non-adjustable common bridge, to the manufacture and repair of belt Very inconvenient. A few years ago, I designed a factory adjustable test bridge, can be used on a variety of grinding machines, the effect is better. Adjustable inspection bridge structure as shown. The structure is relatively simple, mainly composed of the bridge plate body 5, the guide shaft 7 and the adjustment screw 3 and other components. Bridge body has two parallel 90 ° V-shaped groove, respectively, with two guide mandrel 7. Two mandrel parallel to each other, its non-parallelism is small
