Detection positioning structure and automobile part X-ray detection equipment

The utility model provides a detection positioning structure and automobile part X-ray detection equipment using the same. The detecting and positioning structure comprises an X-ray tube moving and swinging mechanism, an imaging plate moving mechanism, a detecting assembly line, a tube head optical shutter and a positioning sensor, after each moving shaft is automatically positioned according to an instruction of an upper computer, high voltage is started, a transillumination picture is automatically grabbed, then each shaft is positioned again according to the instruction of the upper computer, automatic picture grabbing, re-positioning and final discharging are executed in a reciprocating mode, and high-efficiency detection of a certain automobile part is completed. The device is easy to operate by operators, reduces positioning errors, overcomes the defects that conventional detection equipment needs to manually adjust the detection position and complex automobile parts cannot be detected at a time, and ha
