Description

TECHNICAL FIELD

[0001] The present application relates to the field of optical detection, in particular to the field of bearing optical detection, and more particularly to a turbocharger thrust bearing surface detection device. BACKGROUND

[0002] In the production and detection field of turbocharger thrust bearings, the surface quality of the thrust bearing, as the core transmission component of the turbocharger, directly determines the operation stability and service life of the turbocharger. At present, the detection of the surface of the thrust bearing in the industry mainly relies on two types of technical means: one is traditional manual visual detection, and the detection personnel observes the bearing surface through a magnifying glass or a microscope to judge whether there are scratches, depressions, metal spalling and other defects. This kind of way is not only low in efficiency, but also is affected by the differences in subjective judgment of personnel, visual fatigue and other factors, and has a high rate of missed detection of micron-level small defects, which is difficult to meet the full detection needs of mass production; the other is a contact type detection device, such as a probe type profilometer for detecting surface roughness and geometric parameters, which can ensure a certain detection accuracy, but the probe directly contacts the bearing surface during detection, which can easily cause secondary scratches on the surface, and only a local area can be detected at a time, so the full surface of the bearing cannot be quickly covered and detected. With the development of industrial automation technology, some enterprises have tried to introduce basic optical detection equipment, but the existing optical detection scheme still has the following defects: first, there is no targeted bearing positioning and attitude adjustment mechanism, and the bearing is easy to deviate or tilt during transportation, which can cause blurred camera imaging or incomplete detection area, especially for the ring structure of the thrust bearing, it is difficult to ensure uniform detection of the circumferential surface; second, the light source system is simple and does not consider the strong light reflection characteristics of the metal surface of the thrust bearing, which can easily cause light spot interference during detection, and cannot effectively distinguish between normal surface reflection and small defects, resulting in a high defect misjudgment rate; third, the detection and transportation links are disconnected, and most of the equipment needs manual assistance for feeding and discharging, which cannot be seamlessly connected with the production line, and manual sorting is needed after detection, which cannot realize the integration of "detection-sorting", and restricts the overall production efficiency; in addition, the existing optical detection equipment has insufficient synchronous detection capability for the geometric parameters and micro defects of the bearing surface, and often needs multiple devices for step-by-step detection, which increases the equipment investment cost and detection process complexity, and cannot meet the needs of modern production for "high precision, high efficiency and integration" detection.
