Description
Technical field
The utility model relates to bearing roller detection field, specifically a kind of device for gathering bearing roller end face and chamfering image.
Background technology
At present, bearing roller detection system is gradually by the widespread use of roller processing enterprise, this system greatly reduces waste product by automatic monitoring means and enters follow-up processing link, because this systems axiol-ogy often will use rolling body surface image harvester, image collecting device processes in the picture transfer collected to computing machine, therefore the sharpness gathering image decides accuracy of detection, conventional harvester is a camera and a light source, the illumination that light source sends at rolling body on the surface, due to end face information and the chamfering information of mutually confidential collection rolling body, the unsharp impact of illumination is subject in gatherer process, the image collected can not be identified preferably, therefore accuracy of detection is lower, some enterprises are in order to improve accuracy of detection, adopt expensive camera and strengthen the brightness of light source, due to end face image information and chamfering image information will have been gathered, even if light source brightness is very high, can not well make camera photograph end view drawing picture and chamfering image very clearly simultaneously, therefore how to collect end view drawing picture and chamfering image is clearly the technical matters that this area is eager to solve always.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of device for gathering bearing roller end face and chamfering image, coaxial light source and annular light source are rationally set, coaxial light source provides visual field clearly for end face collection, annular light source provides visual field clearly for chamfering collection, ensure that camera can collect end view drawing picture and chamfering image information clearly, improve accuracy of detection.
The technical scheme that the utility model adopts is: for gathering the device of bearing roller end face and chamfering image, comprise an image acquisition units and make image acquisition units can collect the light supply apparatus of tested rolling body image information clearly, described light supply apparatus comprises an annular light source and a coaxial light source, annular light source arranges the outside of tested rolling body, coaxial light source and image acquisition units is set gradually in the dead ahead of tested rolling body end face, the collection face of image acquisition units collects end face image information and the chamfering image information of tested rolling body through the window of coaxial light source, described coaxial light source is provided with a housing, the window for printing opacity is respectively equipped with in the both sides of housing, a LED luminous plaque and tilted-putted lens are provided with in housing, be radiated on the end face of tested rolling body after the refraction of light scioptics that LED luminous plaque sends, image acquisition units successively by the window of the window of housing side, lens and housing opposite side to collect end face image information and the chamfering image information of tested rolling body.
Further optimization this programme, described lens and horizontal plane angle are 45 °.
Further optimization this programme, described lens are dichroic mirror.
Further optimization this programme, described image acquisition units is camera.
The beneficial effects of the utility model are:
One, the utility model are by rationally arranging coaxial light source and annular light source, coaxial light source provides visual field clearly for end face collection, annular light source provides visual field clearly for chamfering collection, ensures that camera can collect end view drawing picture and chamfering image information clearly, improves accuracy of detection, secondly, described coaxial light source is provided with a housing, the window for printing opacity is respectively equipped with in the both sides of housing, a LED luminous plaque and tilted-putted lens are provided with in housing, be radiated on the end face of tested rolling body after the light scioptics refraction that LED luminous plaque sends, image acquisition units is successively by the window of housing side, the window of lens and housing opposite side is to collect end face image information and the chamfering image information of tested rolling body, because these lens adopt dichroic mirror, said structure is made to achieve light source in both gatherer processes non-interference, further raising accuracy of detection.
Two, in order to improve the sharpness of collection, ensure that coaxial light source and annular light source can not be simultaneously luminous, when annular light source is bright, collected by camera is to the chamfering image information of rolling body, when coaxial light source lights, collected by camera, to the end face image information of rolling body, has avoided two light sources so and can not produce interference, disturb to reduce the generation of the phenomenon of image definition.

Embodiment
Elaborate to embodiment of the present utility model below in conjunction with accompanying drawing, the present embodiment, premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in the figure, for gathering the device of bearing roller end face and chamfering image, comprise an image acquisition units 1 and make image acquisition units 1 can collect the light supply apparatus of tested rolling body 4 surface image information clearly, described light supply apparatus comprises annular light source 3 and a coaxial light source 2, annular light source 3 arranges the outside of tested rolling body for light being radiated at the chamfer site of rolling body, coaxial light source 2 and image acquisition units 1 is set gradually in the dead ahead that tested rolling body 4 detects end face, the collection face of image acquisition units 1 collects end face image information and the chamfering image information of tested rolling body 4 through the window of coaxial light source 2,
Described coaxial light source 2 is provided with a housing 201, the window 202 for printing opacity is provided with in the symmetria bilateralis of housing 201, LED luminous plaque 203 and tilted-putted lens 204 are provided with in the inner chamber of housing 201, light scioptics 204 that LED luminous plaque 203 sends are radiated on the end face of tested rolling body 4 after reflecting, image acquisition units 1 successively by the window of the window of housing side, lens and housing opposite side to collect end face image information and the chamfering image information of tested rolling body.
In this programme, in order to realize best result of use, described lens 204 are 45 ° with horizontal plane angle, so, the light scioptics 204 that LED luminous plaque 203 sends just are radiated on rolling body end face after reflecting, and the collection visual angle of image acquisition units just collects the image information of end face through lens, lens as herein described are dichroic mirror, two-phase look mirror (Dichroic Mirrors) is also known as dichroic mirror, be characterized in the light of certain wavelength almost complete through, and the light of other wavelength almost to be reflected completely; Therefore, can ensure that light that LED luminous plaque 203 sends can only reflect and can not be through.
In this programme, described image acquisition units can adopt commercially available camera, and those skilled in the art can select different models according to the difference of required precision.
