The invention relates to an intelligent synchronous lifting detection system in the field of automatic equipment. The intelligent synchronous lifting detection system comprises a cam-driven lifting mechanism and a detection mechanism, wherein the detection mechanism is arranged on the cam-driven lifting mechanism and is driven to carry out lifting movement by the cam-driven lifting mechanism; the cam-driven lifting mechanism comprises a left lifting seat, a right lifting seat and a detection rod; the left lifting seat and the right lifting seat are same and bilaterally-symmetrical in structure; the left lifting seat comprises a left installing seat, a left guide rail and a left cam lifting component; and the detection mechanism comprises a detection main body and a sensing component. The intelligent synchronous lifting detection system has the advantages that when in use, the detection mechanism is directly installed on a horizontal connecting rod of the detection rod, and the horizontal connecting rod is commonly driven by the left cam lifting component and a right cam lifting component to carry out synchronous lifting, so that the detection mechanism can realize synchronous detection action; and a cam transmission structure is adopted for driving without need of any electronic element and additional line arrangement, the whole structure is small and simple, the manufacturing cost is low, and the occupied space is small.
