Description
Technical field
The present invention relates to bearing roller detection field, specifically a kind of detection system for bearing roller.
Background technology
Bearing roller is the vitals of bearing, and the quality of rolling element quality has directly affected reliability and the life-span of bearing. Bearing roller mainly adopts following several detection method at present: artificial visually examine's method, electromagnetic eddy detection method, ultrasonic detection method, magnetic detection method.
Artificial visually examine's method is that the surface to rolling element and end face carry out visualize by human eye, can observe rolling element whether have flaw by means of magnifying glass.
Electromagnetic eddy detection method is that the electric current passing through is under certain condition constant by passing into alternating current to a coil. If near tested rolling element, rolling element surface can induce eddy current, is subject to vortes interference coil, coil current can change. Because whether the size of eddy current has defect and difference with rolling element surface, so the size that coil current changes can reflect that there is zero defect on rolling element surface.
Ultrasonic detection method is to utilize ultrasonic energy to penetrate the depths of metal material, and while entering another cross section by a cross section, the feature that occurs to reflect in interface edge checks a kind of method of rolling element defect, when ultrasonic beam passes to metal inside from rolling element surface by probe, while running into defect and rolling element bottom surface, just there is respectively back wave, on fluorescent screen, form impulse waveform, judge defective locations and size according to these impulse waveforms.
Magnetic detection method is a kind of detection method for detecting ferrimagnet surface and near surface flaw. In the time that rolling element magnetizes, if rolling element surface defectiveness exists, because increasing, the magnetic resistance of fault location produces leakage field, formation local magnetic field, just magnetic shape and the position of display defect herein, thus judge the existence of defect.
All there is certain defect in the use of above-mentioned various detection methods, artificial visually examine's method needs a large amount of testing staff, and people's the long-time observation of eyes easily produces tired, has influence on quality and the efficiency of detection; Electromagnetic eddy detection method can be carried out high speed detection, easily is automated, but is not suitable for complex-shaped part, and can only detect surface and the near surface flaw of conductive material, and testing result is also easy to be subject to the interference of material itself and other factors; Ultrasonic detection method requires smoothly, requires exper ienced reviewer just can distinguish defect kind, defect is not had to intuitive workpiece working surface; Magnetic detection method can not be found rolling element surface pores, folder quarrel and be hidden in the defect of weld seam depths.
Along with scientific and technological progress, some enterprises develop the checkout equipment of automation gradually, this equipment generally includes cleaning device, collator and conveying device and image detection device, although this device tentatively can be realized unmanned automation mechanized operation, but in use, user finds to have following drawback: one, between conveyer and image detection device, generally to be connected a feed mechanism for workpiece transfer, the way of enterprise's routine is to adopt a cylinder to drive a scraping wings to complete this operating process, but this structure practicality is poor, and in pusher process, easily change the position of rolling element, bring difficulty to follow-up image detection, two, the detection efficiency in order to improve, must improve the speed of conveying, but coordinate because image detecting element and conveying device exist the problem disconnecting, and cause occurring the situation of undetected, false retrieval in a large number, make the non-constant of existing roller checkout equipment result of use.
