The invention discloses a propeller type axial fan capable of being used for dynamic balance weight of a rotor and an assembling method of the propeller type axial fan. The problems that an existing rotor dynamic balance weight is inconvenient to operate and how to simply machine a propeller type axial fan on site are solved. A balancing machine (1) is provided with the motor rotor (2) for carrying out a dynamic balance test, axial fans are arranged at the driving end and the non-driving end of the motor rotor (2), impeller sleeves (3) of the axial fans are arranged on the motor rotor (2), 11simple propeller blades (4) are arranged on the impeller sleeves (3) at equal radian intervals, the outer side ends of the 11 simple propeller blades (4) are connected with outer circle connecting rings (5), inverted-trapezoid-shaped ring-shaped grooves (6) and balance weight trapezoid blocks (7) are arranged on the outer circle connecting rings (5), and balance weight block locking jackscrews (9)are arranged between the
