Description

TECHNICAL FIELD

[0001] The application relates to the technical field of bearing detection, in particular to a bearing machining detection system and a detection process. BACKGROUND

[0002] The bearing is an important part in contemporary mechanical equipment, which mainly functions to support the mechanical rotating body, reduce the friction coefficient in the movement process, and ensure the rotation accuracy. The bearing is usually composed of an outer ring, an inner ring and rolling balls or rolling cylinders arranged between the outer ring and the inner ring.

[0003] Since the bearing is usually formed by hot pressing, impurities may occur in the hot pressing process or the hot pressing die and the bearing ring material may move during hot pressing. These conditions are prone to cause a large deviation between the size of the bearing ring and the preset size, so that the bearing ring needs to be screened after hot pressing. The existing detection equipment uses a distance measuring device to detect the inner diameter and the outer diameter of the bearing ring, and usually only detects one point. The flatness of the bearing ring or the circularity of the bearing ring cannot be detected, which has great limitations.

[0004] The size detection device for bearing ring machining and the method are disclosed in the application No. 202110820498.6. The detection of the bearing ring is automatically performed by the detection piece contacting the inner wall of the bearing ring. The detection piece can detect each part of the rotating bearing ring to ensure accurate, comprehensive and complete detection. The inner diameter, thickness, inner wall flatness and arc can be detected at one time, which is fast and convenient.

[0005] During the detection of the bearing clearance, the displacement of the outer ring or the inner ring of the bearing needs to be detected by a micrometer or other equipment, and different directions of force are applied to the inner ring and the outer ring at the same time. According to the relative displacement between the inner ring and the outer ring of the bearing, the bearing clearance is obtained. The fixing and force applying operations of the inner ring and the outer ring of the bearing in the existing test process are usually manual, which causes time-consuming and laborious process and may affect the accuracy of the measurement data.

[0006] Based on the above-mentioned search, it can be seen that the detection surface is single, the roughness of the bearing outer ring is not detected, and the bearing clearance is not detected conveniently and effectively. Therefore, the bearing machining detection system and the detection process are proposed to realize the detection of the roughness of the inner ring and the outer ring of the bearing and the convenient and effective detection of the bearing clearance, and to provide a more convenient and safe detection method for the detection of the machined bearing.
