Bearing surface defect detection device

Abstract

The invention relates to a bearing surface defect detection device which comprises an inspection unit, a conveying unit and a screening unit, the conveying unit and the screening unit are arranged on the two sides of the inspection unit respectively, a bearing reaches the inspection unit through the conveying unit, and the bearing is distinguished and conveyed through the screening unit after inspection of the inspection unit is completed. The inspection unit comprises an expansion fixing shaft and a bearing surface detection component, and the conveying unit and the screening unit are arranged on the two sides of the inspection unit respectively, so that the inspection process of the bearing can be smoother and faster, and the inspection efficiency of the bearing can be effectively improved; the expansion fixing shaft is a part used for fixing the bearing in the inspection unit and fixes the bearing, so that the outer surface of the bearing is prevented from being in contact with other supports to influence the detection, the two side surfaces of the bearing are suspended, and the bearing can be conveniently detected by a bearing surface detection mechanism.

Description

【Technical field】 [0001] The invention relates to the technical field of quality detection, in particular to a bearing surface defect detection device. 【Background technique】 [0002] Bearings are a common type of part geometry in the industrial field. Shaft industrial parts with cylindrical geometry, such as machine tool spindles, bearings, bushings, etc., play a pivotal role in the industrial field, and their quality affects the quality of components and even the entire equipment. service life. However, in the production process of shaft parts, it is inevitable that due to technological or other accidental reasons, the physical or chemical properties of the local area of ​​the surface are not uniform, resulting in quality problems. Therefore, the detection of bearings is very important. [0003] In the prior art, the inspection of the bearing often requires that one inspected surface of the bearing is fixed to the support. When the inspection of the other side is complet...

Problems solved by technology

[0003] However, in the prior art, the detection of bearings often needs to keep one of the tested surface of the bearing fixed with the support. When the other surface is tested, the bearing will be turned over to detect the surface that has just been fixed, which is not only inefficient, but also fixed. The surface is also prone to scratches that affect the quality, so it is necessary to improve
