Wheel hub detection mechanism

A wheel hub detection mechanism comprises a second production line, wherein two sides of the second production line are respectively movably provided with a left clamping mechanism and a right clamping mechanism which are structurally symmetrical leftwards and rightwards, and the left clamping mechanism and the right clamping mechanism are symmetrically arranged leftwards and rightwards along theconveying direction of the second production line; and one side of the second production line is provided with a position adjusting mechanism for a ray emitter. According to the wheel hub detection mechanism, a wheel hub can be automatically clamped and rotated on the production line, defect detection is carried out on the wheel hub through the position adjusting mechanism arranged on the production line, multidirectional detection on the wheel hub is realized through the swinging of the ray emitter, the detection efficiency is high, the detection range is wide, the wheel hub is convenient todetect, the manual partici
