Aluminum alloy hub defect detection device assembly

The invention relates to the technical field of aluminum alloy hub detection equipment, in particular to an aluminum alloy hub defect detection device assembly which comprises a placement unit and a detection unit. The placement unit comprises a fixed seat, a placement seat, a supporting roller and a servo motor; the detection unit comprises a convex lens, a plane mirror and a CCD industrial camera. The detection device assembly has the beneficial effects that the CCD industrial camera in the detection unit is used for detecting the appearance defects of the peripheral surface of the aluminumalloy hub, manual detection is not needed, and the detection efficiency and precision are improved; a convex lens and a plane mirror are arranged, light imaging of a large-range area image of the peripheral surface of the aluminum alloy hub is shrunk through the light condensation capacity of the convex lens, the shrunk light imaging is reflected into the CCD industrial camera through the plane mirror, and thus the area r
