Device for online detection of the defects of a bearing ring end face

Abstract

The invention provides a device for online detection of the defects of a bearing ring end face. The device comprises a ring conveying belt capable of running at an adjustable speed. A visual detectionmodule is arranged above the conveying belt; a photographing area of the visual detection module camera is located at the middle axis of the conveyor belt; a bearing ring position adjusting plate isarranged in front of the camera, and an inferior-quality product removing mechanism is arranged behind the camera. Bearing ring position adjusting plates are arranged on the two sides of the conveyingbelt, obliquely extend out of the middle of the conveying belt and are adjacent to the conveying surface of the conveying belt. When bearing rings conveyed by the conveying belt move to the bearing ring position adjusting plates, the bearing rings deviating from the middle shaft part of the conveying belt can be shifted to the middle shaft part of the conveying belt in sequence; the visual detection module collects and analyzes an overlooking image of the bearing rings through the camera, and when the bearing ring is detected to be an unqualified product, the visual detection module calculates the transmission duration of the unqualified product to the rejection operation area and controls the inferior-quality product rejection mechanism to move the unqualified product reaching the rejection operation area out of the conveying belt according to the duration. The device can efficiently detect the end face of the bearing ring.

Description

technical field [0001] The invention relates to the technical field of bearing production, in particular to an on-line detection device for end surface defects of bearing rings. Background technique [0002] In the production of bearings, the ring is one of the important parts of the bearing. The large end face of the bearing is the reference plane in the bearing processing process. It is necessary to detect the defects such as car waste marks, forging waste points, bumps, and abrasions on the end face of the bearing ring. On-line manual visual inspection after end face grinding requires a large amount of labor and a high rate of missed inspections. How to improve the efficiency of inspection operations is a research direction. Contents of the invention [0003] The invention provides an on-line detection device for the end face defect of a bearing ring, which can efficiently detect the end face of the bearing ring. [0004] The present invention adopts the following tech...
