The invention provides a flexible positioning device for portal box iron end face positioning. The flexible positioning device comprises a rack, a driving device and a moving mechanism are arranged on the rack, the driving device can drive the moving mechanism to transversely move on the rack, an end face limiting plate is connected to the moving mechanism through a rocking arm, a hydraulic oil cylinder is further connected between the end face limiting plate and the moving mechanism, a cylinder base of the hydraulic oil cylinder is hinged to the moving mechanism, and a cylinder head of the hydraulic oil cylinder is hinged to the end face limiting plate. According to the flexible positioning device, the moving mechanism is driven by the driving device to move to the corresponding positions used when box iron in different types is machined, and the hydraulic oil cylinder moves to place down the end face limiting plate so as to achieve box iron end face limiting; when machining on the box iron is finished, the hydraulic oil cylinder moves to fold the end face limiting plate upwards, the box iron passes through the end face limiting plate along a roller way, and the production and manufacturing flexibility is high; in addition, the overall device is arranged above the roller way, so that convenience is brought to repairing and maintaining.
