Motor damping hole reaming device

Abstract

The utility model provides a motor damping hole reaming device, which relates to the technical field of steel rolling equipment and comprises a reaming tool and a damping hole broach. The reaming tool is used for being installed on a motor rotor. The damping hole broaching tool is connected to the broaching tool and comprises a columnar body, the body is provided with a first end and a second end which are opposite in the axial direction, and a plurality of annular tool teeth are sequentially arranged on the peripheral wall of the body at intervals in the axial direction. The outer diameters of the multiple cutter teeth are sequentially increased in the direction from the first end to the second end, and reinforcing ribs are arranged between the side faces, facing the first end, of the cutter teeth and the peripheral wall face of the body. According to the motor damping hole broaching device, the cutter teeth of the damping hole broach are not prone to breakage, the situation that the damping hole broach is frequently replaced in the broaching operation is avoided, and the broaching efficiency is improved.
