First reference mark (not shown) aligns with special angle (such as 0 °) graduation mark on turntable 3, then by 0 ° of quarter on turntable 3
Degree aligns with the second reference mark 11 on base 1, then adjusts displacement mechanism so that detector lens 4 are directed at drag link bushing
On plastics/rubber parts, then stir the shifting part 32, rotate turntable 3, until 0 ° of scale and the second base on base 1
Fiducial mark will 11 is alignd again, completes the detection process to a drag link bushing, in the process, if it find that above-mentioned drag link
There is the crackle more than certain length on plastic part/rubber parts of bushing, then determine that it is defective work, it is preferable that remember at the same time
Record finds the angle corresponding to crackle, in this way, even if detection piece is taken out from the locating slot 31 on the turntable 3, it is only necessary to
The first reference mark is directed at the special angle again, place angle when then rotating turntable 3 to discovery crackle, you can again
In the range of the Crack Rotational to camera lens；By detecting a considerable amount of drag link bushings, statistics obtains the qualification rate of product.
Wherein, it is found that there is the crackle for exceeding certain length on plastic part/rubber parts of above-mentioned drag link bushing can use
In the following manner：
The imaging sensor (such as ccd sensor) of the detector sends the image information collected to server 6,
The server 6 shows picture on the display 7, it is preferable that the server 6 carries out data to the image collected
Analysis and image procossing：Identification of Cracks is carried out to the image collected, and the length of crackle is calculated according to imaging parameters, is sentenced
Whether failure crack length exceedes default length value, if so, then marking the crackle on this image, and marks its length, even
The alert when finding long crack, prompts testing staff's processing.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on, should all be included in the protection scope of the present invention.
