Background
The bearing has wide application in the mechanical field and is an important part in the current mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process and ensure its rotation precision. The bearing is a component for fixing and reducing the friction coefficient of load in the process of mechanical transmission, and when other parts move relative to each other on the shaft, the friction coefficient in the process of power transmission is reduced and the central position of the shaft is kept fixed through the bearing.
The bearings can be classified into rolling bearings and sliding bearings according to the frictional properties of the moving elements. Rolling bearings have been standardized and serialized, but have a larger radial size, vibration and noise, and a higher price than sliding bearings. The rolling bearing generally comprises an outer ring, an inner ring, a rolling body and a retainer. The machining precision and the surface quality of the bearing directly influence the precision of transmission and the service life of machinery. In order to improve the surface quality, the surfaces of the inner raceway of the bearing outer ring and the outer raceway of the bearing inner ring are often subjected to reinforced grinding processing by adopting a metal surface reinforcing technology.

Although the existing electromagnetic centerless clamp can process both the bearing inner ring and the bearing outer ring, the clamp has a complex structure and higher manufacturing cost; in addition, the two supporting blocks can rub the surface of the bearing during rotation, which causes damage to the surface of the bearing.
The utility model discloses a test bed capable of adjusting a bearing clamp.
