Description

Technical Field

[0001] The utility model relates to the technical field of production detection, in particular to a detection tool for surface defects of a fan impeller. Background Technique

[0002] The fan impeller is a key component of the fan. It rotates by receiving wind energy, generates mechanical energy and then drives the fan to operate. When the impeller rotates, it sucks external air into the inlet, and after acceleration, pressurization and other processes, it sprays out from the outlet, generating an air flow and taking away the indoor heat and moisture.

[0003] For the existing detection tool for surface defects of a fan impeller, for example, a clamp for detecting surface defects of a water pump impeller disclosed in the utility model patent with the application number 202220907674.X, its main structure includes a shell. A groove is opened at the top of the shell, and a motor is bolted to the bottom of the inner cavity of the shell. A first gear is fixedly arranged on the output shaft of the motor. A second gear is arranged on the right side of the first gear, and the first gear meshes with the second gear. A rotating rod is arranged inside the shell, and a second gear is fixedly arranged on the surface of the rotating rod. When in use, the water pump impeller is clamped through a limit block, so that the water pump impeller is in a stable state during the flaw detection process, making the detection data of the flaw detector more accurate. At the same time, the size of the clamp can also be adjusted.

[0004] However, most of the existing detection tools still require workers to unload the materials after the detection is completed, and the work efficiency is relatively low. Moreover, the impeller is not cleaned before the detection, and the dust on the surface of the impeller is very likely to affect the detection effect. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a detection tool for surface defects of a fan impeller, which not only blows and cleans the impeller, prevents dust from affecting the detection, improves the detection accuracy, but also facilitates the unloading of the impeller after the detection is completed, and improves the work efficiency.
