Description

Technical Field

[0001] The utility model relates to the technical field of surface defect detection, in particular to an impeller surface defect detection device. Background Art

[0002] Most of the existing impeller surface defect detection equipment uses a detector to take vertical photos of the impeller to identify defects. The impeller is often fixed horizontally on a detection table. However, for impellers with densely distributed blades, only vertical photography and identification will result in occlusions between the blades. The detector cannot perform complete surface defect detection on the impeller. Therefore, the impeller needs to be manually adjusted to multiple angles to complete the detection. However, the manual adjustment of the angle has a large error, and the hand can easily block the impeller, which not only reduces the detection efficiency but also affects the detection quality.

[0003] To solve the above problems, we proposed an impeller surface defect detection device. Utility Model Content
