Tapered roller surface defect detection system

Abstract

The invention discloses a tapered roller surface defect detection system. The tapered roller surface defect detection system comprises a tapered roller end-face detection mechanism and a tapered roller side-face detection mechanism. The tapered roller end-face detection mechanism comprises a feeder, a rotary feeder and an image acquisition device II. The tapered roller side-face detection mechanism comprises 1, a positioning clamp for vertical ordinal falling-off of tapered rollers, 2, a rotation table, 3, an image acquisition device I and 4, a sorting mechanism. The rotation table is located below an outlet of the positioning clamp and is driven by a stepping motor to rotate. One side of the rotation table is provided with the image acquisition device I and the other side of the rotation table is provided with a cylinder II. A push plate II in front of the cylinder II is corresponding to an automatic sorting table. The sorting mechanism receives qualified and unqualified tapered rollers sorted by a movable turnover panel. The tapered roller surface defect detection system effectively improves work efficiency and precision and realizes automatic production.

Description

technical field [0001] The invention relates to the field of bearing roller detection, in particular to a tapered roller surface defect detection system. Background technique [0002] The rolling body of a bearing is an important part of the bearing, and the quality of the rolling body directly affects the reliability and life of the bearing. At present, the following detection methods are mainly used for bearing rolling elements: artificial visual inspection method, electromagnetic eddy current inspection method, ultrasonic inspection method, and magnetic particle inspection method. [0003] The manual visual inspection method is to visually inspect the surface and end face of the rolling element by human eyes, and use a magnifying glass to observe whether the rolling element is flawed. [0004] The electromagnetic eddy current detection method is to pass an alternating current to a coil, and the current passing through it is constant under certain conditions. If the coil...
