Figure 1 As shown, the defective bearing detection device includes an outer ring detection mechanism 1, an inner ring detection mechanism 2, an outer ring drive wheel 3, and an inner ring drive wheel 4. The outer ring drive wheel 3 contacts and drives the outer ring 10 of the bearing to rotate. The outer ring drive wheel 3 contacts the bottom end of the circumferential surface of the outer ring 10, and its rotation causes the outer ring 10 to rotate. The inner ring drive wheel 4 contacts and drives the inner ring 20 of the bearing to rotate. The inner ring drive wheel 4 contacts the highest point of the inner wall surface of the inner ring 20, and its rotation causes the inner ring 20 to rotate.

[0024] like Figure 2 and 3 As shown, the outer ring detection mechanism 1 includes: a first detection box 101, a plurality of first contact plates 104 arranged in sequence, a plurality of first springs 105, and a plurality of first visual detection plates 106. The bottom of the first detection box 101 has a first detection port 102, and a pair of first protrusions 103 are provided on opposite sides of the first detection port 102. The two sides of the first contact plates 104 respectively overlap the first protrusions 103, and the bottom of the first contact plates 104 is used to abut against the top edge of the circumferential surface of the bearing outer ring 10. The bottom end of the first spring 105 is connected to the first contact plate 104. The first visual detection plate 106 is connected to the top edge of the first spring 105.

[0025] like Figure 4 and 5 As shown, the inner ring detection mechanism 2 includes: a second detection box 201, a plurality of second contact plates 204 arranged in sequence, a plurality of second springs 205, and a plurality of second visual detection plates 206. The bottom of the second detection box 201 is provided with a second detection port 202, and a pair of second protrusions 203 are provided on opposite sides of the second detection port 202. The two sides of the second contact plates 204 respectively overlap the second protrusions 203, and the bottom of the second contact plates 204 is provided with an arc-shaped plate 2041, the bottom of which is used to abut against the bottom end of the inner wall of the bearing inner ring 20. The bottom end of the second spring 205 is connected to the second contact plate 204. The second visual detection plate 206 is connected to the top end of the second spring 205.

[0026] When the bearing outer ring 10 rotates, the first contact plate 104 continuously contacts the top position of the circumferential surface of the rotating bearing outer ring 10, and when a protruding defect exists at a certain position of the bearing outer ring 10, the first contact plate 104 at the corresponding position is pushed upward and pops up, and when it pops up, the first visual detection plate 106 is driven upward by the first spring 105, so that the existence of the protruding defect of the bearing outer ring 10 can be directly reflected. When the bearing inner ring 20 rotates, the arc-shaped plate 2041 of the second contact plate 204 continuously contacts the lowest position of the inner wall surface of the rotating bearing inner ring 20, and when a protruding defect exists at a certain position of the bearing inner ring 20, the second contact plate 204 at the corresponding position is pushed upward and pops up, and when it pops up, the second visual detection plate 206 is driven upward by the second spring 205, so that the existence of the protruding defect of the bearing inner ring 20 can be directly reflected. In the embodiment, the first contact plate 104, the first spring 105 and the first visual detection plate 106 jointly constitute a floating detection mechanism for outer ring defect detection, and the elastic buffering action of the first spring 105 makes the first contact plate 104 more easily pushed. The second contact plate 204, the second spring 205 and the second visual detection plate 206 jointly constitute a floating detection mechanism for inner ring defect detection, and the elastic buffering action of the second spring 205 makes the second contact plate 204 more easily pushed. By observing the movement state of the first visual detection plate 106 and the second visual detection plate 206, whether the bearing outer ring 10 and the bearing inner ring 20 have defects and the defect degree can be known, and under the action of the first spring 105 and the second spring 205, the greater the defect degree, the greater the pop-up amplitude and the longer the pop-up time of the first visual detection plate 106 and the second visual detection plate 206.

[0027] The plurality of sequentially arranged first contact plates 104 can reflect the defect conditions at different positions of the bearing outer ring 10, and can be adapted to bearings of various sizes to be detected. Similarly, the plurality of sequentially arranged second contact plates 204 can reflect the defect conditions at different positions of the bearing inner ring 20, and can be adapted to bearings of various sizes to be detected.

[0028] The movement state of the first visual detection plate 106 and the second visual detection plate 206 can be observed by artificial visual observation, or can be observed by setting the first visual detector 107 and the second visual detector 207, and the first visual detector 107 and the second visual detector 207 adopt a camera. The first visual detector 107 is arranged in the first detection box 101, the second visual detector 207 is arranged in the second detection box 201, the collection direction of the first visual detector 107 is toward the plate surface of the first visual detection plate 106, and the collection direction of the second visual detector 207 is toward the plate surface of the second visual detection plate 206.

The lifter 5 can adopt various existing common lifters on the market, such as electric lifters and screw rod lifters, to adjust the lifting height of the outer ring detection mechanism 1, so that the first contact plate 104 can be more flexible to contact the bearing outer ring 10, and to adjust the lifting height of the inner ring detection mechanism 2, so that the second contact plate 204 can be more flexible to contact the bearing inner ring 20, so that the defective bearing detection device of the present application can match various sizes and models of bearings to be detected.

[0032] In an embodiment, the first detection box 101 and the second detection box 201 are both light-tight box bodies, which are beneficial to avoid external image light interference with the detection results when the first visual detector 107 and the second visual detector 207 are installed in the first detection box 101.
