V-block

V-shaped iron is used for shaft inspection, calibration, marking, and can also be used to check the verticality and parallelism of workpieces. Inspection, marking, calibration, and clamping in mechanical processing of shaft components.

The use of V-shaped iron

Mainly used to place circular workpieces such as shafts, sleeves, disks, etc., in order to find and draw the centerline. Generally, V-shaped blocks are a pair of two pieces, and the flat surfaces and V-shaped grooves of the two pieces are ground out during one installation. The parallelism and perpendicularity error between the dimensions of V-shaped blocks and their surfaces are within 0.01 millimeters. The centerline of the V-shaped groove is within the symmetry plane of the V-shaped frame and parallel to the bottom surface. The concentricity and parallelism errors are also within 0.01 millimeters. The half angle error of the V-shaped groove is within the range of ± 30~± 1. The V-shaped block can also be used for marking. The V-shaped block with a clamping bow can firmly clamp the cylindrical workpiece on the V-shaped block and flip it to various positions for marking.

The load-bearing capacity of a V-frame refers to the deformation and deflection of the V-frame after the weight it bears per unit area. For ease of understanding, we can consider the pressure that the V-shaped frame can withstand after placing the workpiece without affecting normal use.
