Description

Technical Field

[0001] The utility model relates to the field of wind blade equipment, in particular to a wind wheel inclination detection tool. Background Art

[0002] The casting of fan impellers is done through the lost wax casting process. After the fan impeller is cast, the end face, shaft hole and other assembly positions of the fan impeller need to be machined to finally obtain a finished product that meets the standards. The clearance control between the end face of the fan impeller blade and the housing and the curvature control of the fan blade are important dimensional standards for fan wind power considerations. Therefore, the fan impeller blade thickness, blade height, and internal and external curvatures all need to be accurately designed. The finished product also needs to be accurately inspected before shipment, so as to strictly control the specifications of the fan impeller blades and ensure product quality and consistency.

[0003] The inclined wind wheel can reduce noise, but the inclined wind wheel is composed of multiple obliquely designed wind blades. Because there are many wind blades that make up the inclined wind wheel, the angle of each wind blade needs to be within the tolerance range. Otherwise, when the angle of the wind blade exceeds the tolerance range, abnormal noise will occur when the inclined wind wheel rotates, and vibration will occur in severe cases. Workers need to check whether the angle of each wind blade is within the tolerance range. The workload is very large, and each company has many products. The wind blade angle and diameter of the inclined wind wheel in each product are different. Therefore, when workers detect the inclined wind wheels of different products, they need to replace different detection equipment. It will take a lot of time to replace the detection equipment, and the cost is very high to specially design and produce a detection equipment for each inclined wind wheel of different sizes.
