Image acquisition device for bearing ring channel surface detection

Technical Field

The utility model relates to an image acquisition device for detecting a channel surface of a bearing ring, which can quickly, efficiently and completely acquire images of the channel surface of the bearing ring.

Background

In the production and processing process of the bearing ring, the channel surface of the bearing ring needs to be subjected to ultra-fine polishing treatment, so that the surface of the workpiece has good surface roughness. When the channel superfinishing treatment of the bearing ring is problematic, the noise, maximum rotational speed, service life and the like of the bearing are greatly affected. Therefore, the corresponding visual detection equipment is needed to collect and compare images of the channel surfaces of the workpieces, so that the surface roughness of the workpieces is detected.

The conventional bearing ring channel surface detection device generally comprises an image acquisition device and a corresponding control system, wherein the image acquisition device is used for transmitting acquired pictures of the surface of a workpiece channel to the control system, and the control system is used for identifying and comparing the acquired pictures to finally judge whether the surface roughness of a product meets the qualification requirement. The existing image acquisition device for bearing ring channel surface detection needs to rotate a workpiece for one circle in the actual image acquisition process so as to ensure the image acquisition integrity. At present, when a workpiece is conveyed to an image acquisition station, the workpiece cannot accurately generate rotation at fixed points, so that the acquisition precision of images is relatively low; and most importantly, after the image acquisition is finished, seamless butt joint of workpiece output cannot be realized, so that a subsequent workpiece to be detected cannot enter an image acquisition station quickly, and the image acquisition efficiency of the workpiece is relatively low.

Therefore, the design can effectively and accurately convey the workpiece to the image acquisition station, and can enable the workpiece to form fixed-point autorotation on the image acquisition station, so that the image acquisition integrity is effectively ensured; the image acquisition device for detecting the bearing ring channel surface can effectively and rapidly output the workpiece after image acquisition is completed, so that the subsequent workpiece to be detected can rapidly enter an image acquisition station, and the image acquisition efficiency of the workpiece is improved.
