The invention provides an IGBT (insulated gate bipolar transistor) module press-fitting device which comprises a first fixing plate, a second fixing plate, a gear transmission mechanism and a plurality of tightening elements. The gear transmission mechanism is arranged between the first fixing plate and the second fixing plate, the tightening elements are driven by the gear transmission mechanism and are matched with press-fitting bolts of IGBT modules, the gear transmission mechanism is provided with an input gear train and a plurality of output gear trains, the input gear train can bear external torque, and the output gear trains can output tightening force to the corresponding tightening elements. The gear transmission mechanism is further provided with intermediate-stage gear trains which are arranged among the input gear train and the output gear trains and are used for transmitting torque of the input gear train to the output gear trains. The IGBT module press-fitting device has the advantages that the
