The invention discloses a device and a method for automatically measuring the dynamic balance of a cross-flow fan. The device comprises a machine tool; the swing frame assembly is arranged on the machine tool and comprises a fan blade support, and the fan blade support is used for clamping and driving the cross-flow fan blade to rotate; the swing frame assembly further comprises a detection frame, and the detection frame is provided with a jacking air cylinder and a plurality of measurement workpieces. A pressure sensor is arranged in the measuring workpiece, and the pressure sensor is used for detecting the dynamic balance of the cross-flow fan blade; and the driving assembly is provided with a driving motor, and the driving end of the driving motor is connected with the fan blade support to drive the cross-flow fan blades to rotate. According to the measuring device, the protrusions evenly distributed on the periphery of the cross-flow fan blade workpiece are utilized, the pressure sensor is adopted to dete
