Abstract

The invention discloses a bearing defect detection device and a bearing defect detection method. The bearing defect detection device comprises a detection part, a loading part, an unloading part, a programmable controller and a PC host, wherein a detected bearing is conveyed to a specified position by the loading part, and then grabbed onto a detection position by a clamping jaw of the detection part; a CCD camera carries out picture acquisition, and then the clamping jaw grabs the detected bearing, overturns the detected bearing by 180 degrees, and places the detected bearing on the detectionposition; the CCD camera carries out picture acquisition again, and after the acquisition is completed, the clamping jaw places the detected bearing onto the unloading part; and the PC host processespictures shot by the CCD camera, and judges whether the detected bearing has defects or not. The bearing defect detection device detects the defects of the bearing on the basis of a visual identification system, is high in efficiency, facilitates to realizing automatic detection, and is capable of detecting the upper surface, the lower surface and the outer ring of the bearing at one detection station, and therefore is compact in structure and low in cost.

Description

technical field

[0001] The invention relates to a bearing defect detection technology, in particular to a bearing defect detection device and a bearing defect detection method. Background technique

[0002] As a common component, bearings are widely used in the industrial field and have different types. The bearing cooperates with the rotation of the mechanical body, which can greatly reduce the resistance during rotation and ensure the accuracy of rotation. Bearing plays an increasingly important role in many industries. It is a component widely used in electromechanical, electrical, petroleum, smelting, and military industries. It can be said that it is needed wherever there is rotation.

[0003] Since the processing of bearings includes multiple processes such as forging, rolling, punching, turning, grinding, heat treatment, etc., various defects may appear on the surface of the outer ring of the bearing. Quality defects on the surface of the bearing outer ring seriousl...
