[0002] Bearings are components used to support and reduce friction in machinery. They allow rotating parts, such as shafts, to rotate smoothly without excessive wear. Bearings usually consist of an inner ring, an outer ring, and rolling elements (such as steel balls or rollers). After the bearing is produced, in order to ensure its quality, a bearing inner ring hole measuring machine is needed to detect the inner ring diameter.
[0003] The existing bearing inner ring hole measuring machine needs to use a bearing fixing device to fix its position when inspecting the bearing inner ring. However, most of the existing bearing fixing devices can only fix the side wall of the bearing from the side direction, and cannot fix the top direction of the bearing. During the inspection process, it is necessary to rotate and inspect different positions of the bearing inner ring. During this process, the bearing is prone to vertical sliding or offset, which affects the accuracy of the bearing inner ring hole measurement results. For this reason, we propose a bearing inner ring hole measuring machine with a bearing fixing device. Utility Model Content
