Abstract
The utility model discloses a detection device detecting a roller chamfer and an end face simultaneously. The device comprises a high-speed camera and a ring illuminator. The ring illuminator is right below the high-speed camera. A spherical integral light source is disposed right below the ring illuminator. The spherical integral light source is formed by a hemisphere and a large ring illuminator. The hemisphere is provided with a gap used to insert a roller. The roller, the hemisphere, the large ring illuminator, the ring illuminator, and the high-speed camera arranged from bottom to top are on a same axis. The detection device detecting a roller chamfer and an end face simultaneously is advantaged in that a non-detection zone of an upper end face and a lower end face of a bearing roller and a chamfer by an original detection device is solved, the detection device realizes omnibearing all-angle nondestructive detection of the upper end face and a lower end face of a bearing roller and a chamfer, bearing roller with defects can be rapidly detected through photographs taken by a high-speed camera, and detection efficiency is high, and detection error does not exist.
Description
Technical field
The utility model belongs to field of non destructive testing, particularly a kind of pick-up unit that simultaneously detects roller chamfer and end face.
Background technology
Roller bearing is the rolling bearing of making rolling body with short cylindrical, circular cone or drum-shaped roller, is the critical component of bearing.Bearing roller requires outward appearance strictly to detect, and comprises physical dimension, External Defect etc., especially the detection of the chamfering on upper and lower end face and the roller to bearing roller.The pick-up unit of bearing roller exists and detects blind area at present, and has the detection defect of chamfering on roller, can not well detect the problem existing in roller end face and chamfering.
Utility model content
Technical problem to be solved in the utility model is, a kind of pick-up unit that simultaneously detects roller chamfer and end face is provided, by two light sources simultaneously by the chamfering of roller and end face reflection in camera, can carry out the detection of the harmless outward appearance vision of comprehensive full angle.
For solving the problems of the technologies described above, a kind of pick-up unit that simultaneously detects roller chamfer and end face that the utility model provides, it comprises high speed camera and annular light source, annular light source be positioned at high speed camera under, under described annular light source, be provided with ball integration light source, described ball integration light source is made up of hemisphere and large annular light source, on described hemisphere, have the breach inserting for roller, the roller being arranged in order from down to up, hemisphere, large annular light source, annular light source and high speed camera coaxial cable.Annular light source is for the situation of upper and lower two end faces of harmless vision-based detection bearing roller, and ball integration light source is for the situation of chamfering on harmless vision-based detection bearing roller, the function having detected when having realized upper and lower end face to bearing roller and chamfering.
When work, roller bearing is partly or entirely in the indentation, there of the large annular light source light source of quadraturing enters ball integration light source, feature by the scattering of ball integration light source forms without blind spot lighting mode, utilize high speed camera to take the image reflecting from the breach of the breach of annular light source and the large annular light source of ball integration light source, check by vision-based detection whether the upper and lower end face of roller and chamfering exist defect.
Adopt after above structure, a kind of pick-up unit that simultaneously detects roller chamfer and end face of the present utility model compared with prior art, have the following advantages: the detection blind area having existed while having solved the upper and lower end face of original detection bearing roller and chamfering, realize the upper and lower end face of bearing roller and chamfering have been carried out to the Non-Destructive Testing of comprehensive full angle, the photo of taking by high speed camera detects the bearing roller that has defect very soon, detection efficiency is high, does not have detection error.
Brief description of the drawings
Fig. 1 is the utility model structural drawing.
Wherein: high speed camera 1, annular light source 2, ball integration light source 3, hemisphere 3.1, large annular light source 3.2, roller 4.
Embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
As shown in Figure 1, a kind of pick-up unit that simultaneously detects roller chamfer and end face that the present embodiment provides, it comprises high speed camera 1 and annular light source 2, annular light source 2 be positioned at high speed camera 1 under, under described annular light source 2, be provided with ball integration light source 3, described ball integration light source 3 is made up of hemisphere 3.1 and large annular light source 3.2, on described hemisphere 3.1, have the breach inserting for roller 4, the roller 4 being arranged in order from down to up, hemisphere 3.1, large annular light source 3.2, annular light source 2 and high speed camera 1 coaxial cable.
The detection of chamfering: the light source on the large annular light source 3.2 of ball integration light source 3 is irradiated on hemisphere 3.1, reflex to by hemisphere 3.1 in the chamfering of roller bearing, utilize high speed camera 1 to take the image reflecting from the breach of large annular light source 3.2, processing situation in chamfering is presented on the photo that high speed camera 1 takes completely, is convenient to chamfering and detects.
The detection of end face: in detecting roller chamfer, annular light source 2 is directly irradiated to light source on the end face of roller, utilize high speed camera 1 to take the image reflecting from the breach of annular light source 2, processing situation on end face is presented on the photo that high speed camera 1 takes completely, is convenient to end face and detects.
Claims (1)
1. one kind is detected the pick-up unit of roller chamfer and end face simultaneously, it comprises high speed camera and annular light source, annular light source be positioned at high speed camera under, it is characterized in that: under described annular light source, be provided with ball integration light source, described ball integration light source is made up of hemisphere and large annular light source, on described hemisphere, have the breach inserting for roller, the roller being arranged in order from down to up, hemisphere, large annular light source, annular light source and high speed camera coaxial cable.
