Bearing manufacturing physical property detection method

Abstract

The invention relates to a bearing manufacturing physical property detection method. A bearing manufacturing physical performance detection device is used in the method. The bearing manufacturing physical property detection device comprises a workbench, a clamping and fixing mechanism and a detection mechanism, clamping mechanisms are equidistantly mounted at the upper end of the worktable from left to right; a detection mechanism is arranged at the upper end of the workbench; the upper end of the detection mechanism is positioned below the lower end of the clamping mechanism; according to theinvention, the design concept of a multi-station and dual-detection structure is adopted to detect the physical performance of bearing manufacturing; according to the bearing quality screening device, the rotating smoothness of multiple bearings and the quality of the inner surface of the bearing outer ring can be detected at the same time, then the bearing quality screening quality and speed areimproved, and meanwhile, multiple auxiliary clamping and limiting structures are additionally arranged on the basis of the clamping mechanism to reduce the probability of relative rotation between the bearing outer ring and the bearing inner ring.

Description

technical field [0001] The invention relates to the technical field of bearing manufacturing, and relates to a method for detecting physical properties of bearing manufacturing. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The bearing is composed of inner ring, outer ring, rolling body, cage Composed of grease and grease, the early form of linear motion bearings was to place a row of wooden rods under a row of pry plates. Modern linear motion bearings use the same working principle, sometimes with balls instead of rollers. The simplest swivel bearing is the bushing bearing, which is just a bush sandwiched between the wheel and the axle. This design was then replaced by rolling bearings, that is, replacing the original bushing with many cylindrical rollers. Each rolling body i...

Problems solved by technology

[0003] 1. For small and medium-sized bearings, the method of manually rotating the bearing to check whether it rotates smoothly is usually used, but this method takes a long time to work and results in low work efficiency, and this method can only control the rotation of the bearing The quality inspection of the inner surface of the outer ring of the bearing is ignored, and the results of manual inspection are prone to errors due to the workers' own feelings;

[0004] 2. It is common to fix the outer ring or the inner ring of the bearing for testing. The clamping degree of the outer ring or the inner ring of the bearing is low, so that the overall stability of the bearing is low, and it is easy to occur between the inner and outer rings of the bearing. Relative rotation results in inaccurate rotation detection results, and common detection devices show low accuracy of detection results, making it difficult for workers to quickly and clearly observe the results to screen bearings
