Embodiment 1

[0034] See attached figure 1 , attached figure 2 , attached image 3 , attached Figure 4 And attached Figure 5 , the tapered bearing roller surface defect detection device of the present invention includes a feed hopper 1, a material channel, a dial 3, a CCD camera 4, an industrial computer 6, a light source 5, a friction wheel 9, a detection table 14, a baffle plate 10, an ejector device 11 and conveyor belt 13;

[0035] The feed hopper 1 is arranged at the inlet end of the feed channel, the inlet end of the feed channel is placed obliquely higher than the outlet end, the dial 3 is arranged above the outlet end of the feed channel, and the dial 3 Intermittently move the tapered bearing rollers;

[0036] The inlet end of the detection platform 14 is connected with the outlet end of the material channel, and the outlet end of the detection platform 14 is provided with a friction wheel 9, and the friction wheel 9 cooperates with the tapered bearing roller at the outlet e...

Embodiment 2

[0050] The difference between this embodiment and the first embodiment is that: the material channel is a trapezoidal material channel, and the inclination angle of the upper surface of the trapezoidal material channel is the same as the cone angle of one-half of the tapered bearing rollers.

Abstract

The invention discloses a device and a method for detecting defects on the surface of a conical bearing roller, belongs to the technical field of photoelectric detection, and aims to solve the problems of inaccuracy in artificial detection, injury to human eyes, low detection efficiency and high cost. According to the invention, a feed hopper of the device is arranged at the inlet end of a material passage, and a drive plate close to the upper part of the outlet end of the material passage intermittently drives the conical bearing roller; the inlet end of a detection table is connected with the outlet end of the material passage, a friction wheel is arranged at the outlet end of the detection table, the friction wheel is matched with the conical bearing roller at the outlet end of the detection table, and the friction wheel is connected with a conveying belt through a baffle; a charge coupled device (CCD) camera is arranged above the outlet end of the detection table, a light source is arranged between the CCD camera and the detected conical bearing roller, and an ejection device is arranged at one end, connected with the baffle, of the conveying belt. According to the method, an image of the surface of the detected conical bearing roller is acquired in real time through the CCD camera and transmitted to an industrial personal computer to judge whether defects exit, and the industrial personal computer controls the ejection device to eject the conical bearing roller with defects.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection, and in particular relates to a device and method for detecting surface flaws of tapered bearing rollers. Background technique [0002] For rolling bearings, since the bearing rollers are rolling when they are working, their surface quality directly determines the working performance and even the service life of the bearing. During the processing of bearing rollers, due to factors such as processing equipment and raw materials, small surface defects such as scratches, abrasions, impurities, and small spots will occur on the surface of the rollers. These defects are collectively referred to as surface defects of the rollers. sick. Among the factors affecting bearing life, precision and noise, the surface roughness of bearing rollers accounts for about 50% of various influencing factors. Therefore, strict surface defect detection must be carried out on bearing rollers before leaving...
