Description

Technical Field

[0001] The utility model relates to a grinding device, in particular to a bearing inner ring grinding device, belonging to the technical field of bearing processing equipment. Background Art

[0002] Bearing is an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Under a certain load, the number of revolutions or hours that the bearing experiences before pitting occurs is called the bearing life. The life of a rolling bearing is defined by the number of revolutions (or the number of hours of work at a certain speed): within this life, the bearing should have initial fatigue damage (peeling or defect) on any of its bearing rings or rolling elements. However, whether in laboratory tests or in actual use, it can be clearly seen that the actual life of bearings with the same appearance under the same working conditions is very different. In addition, there are several different definitions of bearing "life", one of which is the so-called "working life", which means that the actual life that a bearing can achieve before damage is caused by wear and tear. Damage is usually not caused by fatigue, but by wear, corrosion, seal damage, etc. In order to determine the standard of bearing life, the bearing life is linked to reliability. Due to differences in manufacturing accuracy and material uniformity, even if the same batch of bearings of the same material and size are used under the same working conditions, their life span is different;

[0003] A Chinese patent publication (CN202223515935.2) discloses an inner ring grinding device for bearing manufacturing. When different inner diameters are required, two grinding sand plates are driven away from each other by a power motor, so that the two grinding sand plates can contact the inner ring of the bearing with a larger inner diameter, thereby grinding the inner rings of the bearings with different inner diameters, which greatly improves the applicability of the device. However, the application still has the following technical problems when in use: when the bearing inner ring grinding device is in use, it is necessary to manually fix and remove the bearing to be polished, resulting in low work efficiency and inability to quickly fix and remove the bearing to be polished;
