Embodiment 1

[0045] Such as Figure 1-3 shown.

[0046] Taking the aspect ratio of INA-K06 type sliding bearing = 0.6 and satisfying the condition of no more than 2 as an example, the product testing method for outer surface diameter, height and inner surface coating peeling is explained in detail. The number of testing is 50,000 pieces.

[0047] A method for multi-index high-speed dynamic detection and material distribution of an annular sliding bearing, comprising the following steps:

[0048] First, make the driving roller 12 rotate counterclockwise, so that the sliding bearing or bushing will roll clockwise to a low position under the action of gravity and the friction of the conveyor belt. When the sliding bearing is in the detection position, it will stop moving down under the action of the tooth surface of the gear 26. And make a fixed axis rotation;

[0049] Secondly, the camera I4 is used to collect images on the outer surface of the sliding bearing or the bushing, and the camer...

Embodiment 2

[0057] Such as Figure 1-3 shown.

[0058] A device for multi-index high-speed dynamic detection and material distribution of annular sliding bearings. The main and driven rollers 12, 1 are installed on the base 17 through high, middle and low brackets 19, 16, 13, and the brackets 19, 16, 13 are connected to the base They are connected by studs 18, and the central shafts of the main and driven rollers 1, 12 and the high and low brackets 19, 13 are respectively fixed by deep groove ball bearings, such as figure 1 Shown; The right side of driving drum 12 is connected with motor II27 by shaft coupling 28, as figure 2 As shown; the main and driven rollers 12 and 1 are kept at a certain distance through the crossbeam 14, and the conveyor belt 20 is set in the middle, and the inclination angle of the conveyor belt can be set between 30-50 degrees; the feeding device 2 and the raceway I II III 11 are fixed on the On the beam 14, and keep a distance of 5~8 mm from the upper surface...

Abstract

The invention discloses a multi-index high-speed dynamic detection and material dividing method and device of an annular sliding bearing. According to the method, multiple indexes of the outer surface size and the inner surface coating defects of the sliding bearing are dynamically detected through machine vision, material division is carried out on workpieces according to the detection result through the color recognition technology of machine vision, and the method has the advantages of being high in detection efficiency, accurate in recognition, high in automation degree and the like. The device comprises a roller, a conveying belt, a high-definition camera, a digital control spraying device, an electric switch, a computer system and the like, wherein the high-definition camera is used for carrying out multi-index dynamic detection on the sliding bearing rotating in a fixed-axis mode, whether defects exist is recognized and material division is carried out through the high-definition camera and a limiting switch, the detecting speed is as high as 120-180 per second, the recognition accuracy is as high as 100 percent, automatic production is fully realized, and the detection cost is largely reduced.

Description

technical field [0001] The invention relates to a detection technology of mechanical parts, in particular to a sliding bearing or shaft sleeve defect detection technology, in particular to a multi-index high-speed dynamic detection and material distribution method and device for an annular sliding bearing. technical background [0002] Sliding bearings are widely used in low-speed and heavy-duty working conditions, or operating parts where maintenance and lubrication are difficult. They are important supports for shafts and other rotating components. Therefore, their dimensional accuracy and surface quality are directly related to mechanical equipment. Performance and lifespan. At present, the detection of the dimensional accuracy and inner surface defects of sliding bearings, especially the detection of the inner surface of sliding bearings, mainly relies on manual visual observation, so the inspection efficiency, accuracy and reliability of the inspection cannot meet the ...
