Description

Technical Field

[0001] The utility model belongs to the technical field of flaw detection equipment, in particular to a roller flaw detection device. Background Art

[0002] The rollers of large bearings need to bear huge loads when working, so during the manufacturing process, flaw detection is required to ensure that the roller bearings work stably and reliably.

[0003] As we all know, flaw detection requires the use of specific flaw detectors. In the specific working process, the roller to be detected needs to be placed on the conveying device first, and then the conveying device conveys the roller to the designated flaw detection area, and the flaw detector performs flaw detection on the roller. However, most of the existing conveying devices use two tilted metal conveyor rollers. During the conveying process, the two metal conveyor rollers will have hard contact with the rollers, squeezing the rollers on both sides, which can easily cause the rollers to jump during conveying and the conveying to be unstable, which invisibly increases the scrap rate of the rollers. In addition, due to the oil stains attached to the surface of the rollers, it will also lead to low conveying efficiency. Utility Model Content

[0004] The utility model aims to provide a roller flaw detection device to solve the problem that conventional metal conveying rollers in the prior art can cause unstable roller conveying and low conveying efficiency.

The driving end of the feeding drive is connected to the first end of the feeding channel, and the second end of the feeding channel is connected to the conveying platform. The feeding drive drives the rollers to be sequentially conveyed to the conveying platform through the feeding channel.

[0008] The conveying unit includes two conveying rollers, both of which can be rotatably installed on the conveying platform. The surfaces of the two conveying rollers are provided with a buffer rubber layer. The two conveying rollers are arranged at a specified angle so that the rollers can be conveyed from the first end of the conveying platform to the second end of the conveying platform when rolling. During transportation, the buffer rubber layer buffers the extrusion force exerted on the rollers to prevent the rollers from jumping.

[0009] A discharge channel is provided at the second end of the conveying platform, the flaw detection device is provided on the conveying path of the conveying unit, the flaw detection device is configured to perform flaw detection on the rollers, the collecting device is provided at one end of the discharge channel, and the collecting device is configured to collect qualified rollers after detection.
