Embodiment 1
[0022] Example 1: Example when the rolling elements are rollers
[0023] Such as figure 1 As shown, the automatic detection device for the full surface defect of the bearing roller provided in this embodiment is mainly composed of a camera 1 , a conveyor belt 3 with a slot array structure, a light source 4 , a rejecting device 6 and an electric drum 9 . The specific process of detection is as follows: firstly, the detection device undertakes the production end of the roller, and the rolling body 2 to be tested is a bearing roller. Conveyed to the slot array structure conveyor belt 3 by the feeder, the motorized roller 9 drives the slot array structure conveyor belt, using the friction between the rollers and the bottom plate 12 below the conveyor belt 11 to make the rollers turn over and pass through the slots 10 continuously Below the camera, the image of the full surface of the roller is collected by the camera, and then the computer processes the image in real time to obta...
Embodiment 2
[0028] Example 2: Example when the rolling elements are balls
[0029] Such as Figure 10 As shown, the automatic detection device for full-surface defects of bearing balls provided in this embodiment is mainly composed of a camera 1 , a conveyor belt 3 with a slot array structure, a light source 4 and an electric drum 9 . In order to improve the detection efficiency, the conveyor belt has four S-shaped slot channels. The active rolling diameter is larger than the driven rolling, so that the conveyor belt has a certain slope. The specific process of detection is as follows: firstly, the detection device undertakes the ball production end, and the rolling body 2 to be tested is a bearing ball. The feeder controls the balls to be delivered to the slot array structure conveyor belt 3 one at a time, and the electric drum 9 drives the slot array structure conveyor belt to reverse. The balls use gravity to roll freely in the slots. The roller reverses and cooperates with the fric...
Embodiment 3
[0031] Example 3: Example when the rolling elements are tapered rollers
[0032] Such as Figure 11As shown, the automatic detection device for outer surface defects of bearing tapered rollers provided in this embodiment is mainly composed of a camera 1 , an electric turntable 17 , a turntable 16 with a trapezoidal hole array structure, a light source 4 and a base 12 . Based on the characteristics of the geometric structure of the tapered rollers, an annular turntable with a conical hollow groove is designed to ensure the uniform rotation of the tapered rollers by means of rotation. The specific process of detection is as follows: First, the detection device undertakes the tapered roller production end, and the rolling element 2 to be tested is a bearing tapered roller. The feeder transports the tapered rollers to the trapezoidal hole array structure turntable 16, and the electric turntable 17 drives the trapezoidal hole array structure turntable 16 to rotate, using the frict...
