Description

Technical Field

[0001] The utility model relates to the technical field of fan casing detection, in particular to a new fan detection tool. Background Art

[0002] Fans are an essential component of the ventilation industry and are increasingly used. During fan production and application, manufacturers typically sell finished fans to end customers, who then install them into their desired complete machine. During this process, the manufacturer assembles the fan's casing, rotor, and impeller. Prior to assembly, personnel perform precision testing on the various standard pre-installed connection holes in the fan casing to ensure they meet specification requirements for subsequent complete machine assembly.

[0003] Currently, the hole measurement of fan casings is generally carried out by plugging and testing with a mandrel. However, using a mandrel to test the holes in the fan casing requires advance training of workers. The workers are required to stabilize the casing themselves and then select the angle and position for plugging. This process is prone to errors and cannot meet the accuracy requirements of industrialization, and is prone to producing defective and scrapped products.

[0004] Based on this, the utility model designs a new air fan detection tooling to solve the above problems. Summary of the Invention
