Description
Technical Field
[0001] The utility model relates to the technical field of machinery, in particular to a bearing outer ring sorting device. Background Art
[0002] The bearing is generally composed of an outer ring, an inner ring, a steel ball, a cage and a sealing ring. The inner surface of the outer ring is provided with an annular groove and a dustproof groove. The cross section of the groove is arc-shaped and matches the diameter of the steel ball. After the bearing is assembled, one side of the steel ball is embedded in the groove and contacts the groove surface. After the outer ring of the bearing is rough-machined to form a groove through a lathe, the outer ring groove is fine-ground by a grinder. When the bearing hub unit is assembled with a matching sleeve, it is necessary to assemble according to the requirements of the inner ring raceway size, the small inner ring raceway size, the outer ring raceway size, the steel ball size, the inspection of the steel ball and the inner ring, the small inner ring and the outer ring, and the grade of the bearing, so the sorting accuracy of the raceway size of the inner ring, the outer ring and the small inner ring is very important. In the existing technology, most of them adopt manual sorting, which is affected by various factors, and not only the sorting accuracy is low, but also the sorting efficiency is low. A small part adopts sorting mechanism for sorting. Although the sorting efficiency is improved, during the sorting process, the contact between the inspection fixture on the sorting mechanism and the raceways of the inner ring, small inner ring and outer ring is hard contact, which is not only easy to damage the raceways of the inner ring, small inner ring and outer ring, but also the sorting accuracy is low and cannot meet the use requirements.
