Medium-large size bearing detection device

The invention relates to the technical field of gear manufacturing, in particular to a medium-large size bearing detection device. By arranging the rotating disc for placing the bearing, the bearing can rotate along with the rotating disc after being placed, and each part of the bearing can be subjected to magnetic emission detection through the detection assembly in the rotating process, so that whether air holes, slag inclusion, cracks and the like exist in the bearing or not is judged, the mounting seat is further arranged, and the rotating wheel abutting against the bearing is arranged on the mounting seat; the rotating wheel can limit the displacement of the bearing and can also rotate along with the bearing, the influence on rotation of the bearing is reduced, meanwhile, the adjusting groove is formed in the mounting base and penetrates through the mounting base, the position of the mounting base can be adjusted by disassembling the bolt, and the bearing can be adjusted by adjusting the position of the
