Portable hardness detection auxiliary tool for tooth root and tooth surface of slewing bearing

The portable hardness detection auxiliary tool comprises a supporting block, the supporting block comprises a tooth root detection hole, a tooth root supporting surface, a tooth surface detection hole and a tooth surface supporting surface, and the tooth root detection hole and the tooth surface detection hole are through holes penetrating through the supporting block; wherein the tooth root detection hole is perpendicular to the tooth root supporting surface, the tooth surface detection hole is perpendicular to the tooth surface supporting surface, and the tooth root detection hole is located in the center of the tooth root supporting surface. The device solves the problems that the detection speed is low and the detection result is too discrete in the tooth root and tooth surface hardness detection process. The bearing tooth surface and tooth root hardening layer detection device has the advantages that the speed and the detection precision of bearing tooth surface and tooth root hardening layer detection a
