Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a clamp for bearing processing. Background Art

[0002] Bearings are 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. According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial dimensions, vibrations and noise are larger, and their prices are also higher. Rolling bearings generally consist of four parts: outer ring, inner ring, rolling element and cage. According to the shape of the rolling element, rolling bearings are divided into two categories: ball bearings and roller bearings.

However, the bearing processing fixture has the disadvantages of not being able to process bearings of different diameters, and the bearing processing fixture is not able to adjust the fixed height according to bearings of different thicknesses, and is relatively not very firm during the clamping process.
