Abstract
The utility model discloses an automatic detection device for the flaw detection of the magnetic powder on metal shaft part surface, comprising a video camera, a light source seat, a light source, a diffusion plate, a rotating drive frame, a counter, a programmable control and digital image processor, the camera is mounted above the rotating drive frame by the light source seat, the light source is arranged at both ends of the light source seat, a light scattering plate is mounted in the front of the light source and is in the projecting imaging relation with the detected part of the rotating drive frame, the camera is connected with the programmable control and digital image processor by leads, the counter is arranged on the rotating drive frame, the rotating drive frame and the counter are connected with the programmable control and digital image processor by leads. The image of the detected part is collected by the camera and is treated and analyzed by the programmable control and digital image processor, the defect magnetic mark on the surface of the part in the flaw detection can be judged, thus avoiding the effect of the nondeterminacy of people judgment and the subjective factors such as fatigue, fault and the like.
Description
Technical field
The utility model discloses a kind of metal shaft class piece surface magnetic powder inspection automatic detection device, belongs to mechanical part pick-up unit technical field.
Background technology
Magnetic powder inspection is a kind of method that very detects the metal surface defects of mechanical parts widely of using, and existing magnetic powder inspection device is made up of exciting part, magnetcisuspension supernatant liquid spraying mechanism, demagnetization parts.The shortcoming of this magnetic powder inspection device is, it when carrying out flaw detection the detected a flaw magnetic trace of piece surface of the visual inspection of personnel selection, because the judgement of surface imperfection magnetic trace is finished by the people, and testing result will be subjected to the influence of the subjective factors such as uncertainty, fatigue and error of people's judgement inevitably.
Summary of the invention
The utility model proposes a kind of metal shaft class piece surface magnetic powder inspection automatic detection device, this device is installed on the existing magnetic powder inspection device, solved based on the magnetic powder inspection technology and detected metal shaft class piece surface defect problem automatically.
Metal shaft class piece surface magnetic powder inspection automatic detection device of the present utility model is by forming as the lower part: video camera, light source base, light source, astigmatism plate, rotation bogie, counter, control able to programme and digital image processor, video camera is installed in the top of rotation bogie by light source base, light source is located at the two ends of light source base, the light scatter plate is equipped with in the front of light source, with the detected part formation projection imaging relation of rotation bogie; Video camera links by lead and control able to programme and digital image processor, and the rotation bogie is provided with counter, and rotation bogie and counter link by lead and control able to programme and digital image processor.
Good effect of the present utility model is: by the detected part image of camera acquisition, through control able to programme and digital image processor Treatment Analysis, to being judged automatically, avoid the influence of the artificial subjective factors of judging such as uncertainty, fatigue and error by flaw detection piece surface defective magnetic trace.
Description of drawings
Fig. 1 is the utility model structure principle chart.
Embodiment
According to shown in Figure 1, detected part 5 (what show among the figure is metal axial workpiece end view) is installed on the rotation bogie 8, rotation bogie 8 is for axially stepping up mechanism, its driving mechanism is connected with the control circuit of control able to programme and digital image processor 7, the anglec of rotation of the detected part 5 of controlling and driving; Video camera 1 is installed in the top of rotation bogie 8 by light source base 2, light source 3 is located at the two ends of light source base 2, light scatter plate 4 is equipped with in the front of light source 3, the light that light source 3 sends shines on the detected part 5 after by scatter plate 4 scatterings, constitutes the projection imagings relation with the detected part 5 of rotation bogie 8; Video camera 1 links by lead and control able to programme and digital image processor 7, video camera 1 and rotation drive and counter 6 control able to programme and digital image processor 7 control under coordination, when rotation bogie 8 and counter 6 drives detected part 5 and rotates to an angle, the image on detected part 5 surfaces of video camera 1 picked-up, and be sent in control able to programme and the digital image processor 7, carry out Flame Image Process and identification for control able to programme and digital image processor 7.
