铸铁V型架主要用来安放轴、套筒、圆盘等圆形工件，以便找出中央线与划出中央线。为了便于理解，我们可以看作V型架放好工件后，在不影响正常使用的情况下，V型架所能够承受的压力。
V型架按JB/T8047-95尺度制造，采用HT200材质，成对供给，主要用于精密轴类零件的检测、划线、定仪及机械加工中的装夹。
铸铁V型架的尺寸相互表面间的平行度，垂直度误差在0.01毫米之内，V型铁V型槽的中央线必须在v型架的对称平面内并与底面平行，同心度，平行度的误差也在0.01毫米之内，V型槽半角误差在±30~±1范围内。一般铸铁V型架都是一副两块，两块的平面与V型槽都是在一次安装中磨出的。好比：2000mm×4000mm的V型架可以放置重量为64吨的工件，这样V型架的承载，我们可以根据V型架的技术要求本着以最低的本钱达到最好的设计效果。铸铁V型架的承载要求：铸铁V型架的承载是指V型架单位面积承受的重量后，V型架的变形挠度。
Technical requirements for cast iron
V-frame
The cast iron V-frame is mainly used to
place circular workpieces such as shafts, sleeves and discs in order to find
the center line and draw the center line. In order to facilitate understanding,
we can consider the V-frame can withstand the pressure of the V-frame without
affecting normal use.
The V-frame is made according to the
JB/T8047-95 scale. It is made of HT200 material and is supplied in pairs. It is
mainly used for the inspection, scribing, setting and machining of precision
shaft parts.
The parallelism between the dimensions of
the cast iron V-frames, the verticality error is within 0.01 mm, the center
line of the V-shaped V-groove must be in the symmetry plane of the v-frame and
parallel to the bottom surface, concentricity, parallelism The error is also
within 0.01 mm, and the V-groove half-angle error is in the range of ±30~±1.
Generally, the cast iron V-frames are a pair of two pieces, and the two planes
and the V-shaped grooves are all ground in one installation. For example, the
2000mm×4000mm V-frame can hold a workpiece with a weight of 64 tons, so that
the V-frame can be loaded with the best design according to the technical
requirements of the V-frame. Bearing requirements of cast iron V-frame: The
load of cast iron V-frame refers to the deformation deflection of the V-frame
after the weight per unit area ofthe V-frame.
