Technical Field
The utility model relates to a fan diameter measurement's field, concretely relates to frock of accurate measurement fan diameter.
Background
Fans are widely used for ventilation, dust exhaust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, and for ventilation and draught of boilers and industrial furnaces and kilns; cooling and ventilation in air conditioning equipment and household appliances; drying and selecting grains, wind source of wind tunnel and inflation and propulsion of air cushion ship.
Most of existing fan diameter measuring devices adopt a mode of measuring the radius of a fan, and then the diameter of the fan is obtained through calculation. Such a measurement mode is not only large in accumulated error, but also the fan blades are often not at the same height because the central point of the fan is not easy to be accurately positioned, so that common caliper measurement equipment cannot directly measure. Therefore, it is necessary to develop a tool capable of accurately measuring the diameter of the fan.

Furthermore, a plurality of groups of positioning and mounting holes with different sizes are formed in the bottom plate and used for fixedly mounting fans with different sizes.
Further, the measuring range of the vernier caliper to the diameter of the fan is
Furthermore, the centers of the left vertical rod and the right vertical rod are opposite to the center of the position of the fixed fan on the bottom plate.
The utility model has the advantages that: the diameter of the fan (or the fan blade rotor) can be accurately, directly and conveniently measured, and the accuracy of measured data reaches 0.01 mm; the fan has universal applicability to fans with different diameters.
