Description
Technical Field
[0001] This invention relates to the field of bearing manufacturing and processing fixtures, specifically to an adjustable bearing manufacturing and processing fixture and its usage method. Background Technology
[0002] Bearings are essential components in modern machinery. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Early linear motion bearings consisted of a row of wooden rods placed under a row of skids. Modern linear motion bearings use the same working principle, although sometimes balls are used instead of rollers. The simplest rotary bearing is the bushing bearing, which is simply a bushing sandwiched between a wheel and an axle. This design was later replaced by rolling bearings, which use many cylindrical rollers instead of the original bushing, with each rolling element acting like an individual wheel.
[0003] Most adjustable bearing manufacturing fixtures on the market cannot simultaneously clamp and fix both the outer and inner rings of a bearing when holding it. This causes the outer or inner ring of the bearing to rotate during processing, and the bearing is prone to tilting when clamped, which brings inconvenience to users. Summary of the Invention
