Description

Technical Field

[0001] The utility model embodiment relates to the technical field of fan blade manufacturing, and in particular to a universal adjustable profile positioning device for axial flow fan blades. Background Art

[0002] Axial flow fans are fans that use the thrust of the blades to force the gas to flow in the axial direction. They are usually composed of a collector, an impeller, a casing, and a shaft. Large axial flow fans are also equipped with fairings, guide vanes (referred to as "guide vanes", including front and rear guide vanes), tail guides, and diffusers. When the prime mover drives the impeller to rotate in the casing, a certain installation angle between the shaft and the propeller-shaped blades generates thrust on the gas, pushing the gas to flow continuously along the shaft direction, so that the gas is continuously inhaled and discharged.

[0003] There are many varieties and models of large, medium and small blades in axial fan blades with different geometric dimensions. When inspecting and processing the relative surface and the position relationship between the root crown and the handle, the special positioning templates are replaced according to the different sizes and models. Therefore, it is necessary to store special positioning templates of different sizes and models, which leads to high cost of use. Utility Model Content
