The utility model discloses a detection device can realize automated inspection to wheel hub, and it is accurate to detect, does not rely on artifical judgement.
Description
Technical field
This utility model relates to field of hub, is specifically related to a kind of hub defect detecting device based on machine vision。
Background technology
Wheel hub is as the vitals supporting automobile, its quality is very crucial, in prior art, wheel hub is mostly by forging, having cast, the intensity making wheel hub reaches certain requirement, if there is the defects such as crackle in wheel hub, so in use will be likely to occur major accident, it is therefore desirable to the quality of wheel hub is checked, how efficiently and accurately check that wheel hub quality becomes the direction that technical staff pursues。
Utility model content
Utility model purpose: this utility model is intended to the defect overcoming prior art, it is provided that a kind of hub defect detecting device based on machine vision。
Technical scheme: a kind of hub detection device, fix the riser being connected with base plate including base plate, described riser is provided with through hub centre hole, and the rotating shaft that can rotate, described riser is additionally provided with the slide block that can slide up and down, being fixed with motor on described slide block, motor output shaft is provided with friction roller, and described friction roller can contact the outer rim of wheel hub and drive wheel hub to rotate；Described detecting device also includes to gather the first image acquisition part of outer rim image and can gathering the second image acquisition part of interior wheel rim image。
Further, described first image acquisition part is fixed on described riser by the first support。
Further, described second image acquisition part is hinged on base plate by the second support, and described second support is " L " type support, and one end of described second support is fixing with the second image acquisition part to be connected, and the other end is hinged on described base plate。
Further, described first image acquisition part and the second image acquisition part are CCD camera。

Further, described friction roller is rubber friction roller。
Further, detecting device also includes the controller that is connected with motor, the first image acquisition part, the second image acquisition part。
Beneficial effect: hub detection device of the present utility model, it is capable of the detection simultaneously to the whole outer rim of wheel hub, interior wheel rim and wheel rim, and is capable of the detection of whole circumferential surface, and testing result is based on image procossing, it is independent of artificial, detects more accurately and standardization。
Accompanying drawing explanation
Fig. 1 this utility model detecting device schematic diagram；
Fig. 2 is view before detecting device work。
Detailed description of the invention
Accompanying drawing labelling:
1 base plate；2 risers；3 motors；3.1 motor output shafts；3.2 slide blocks；4 friction rollers；5 first image acquisition part；5.1 first supports；6 second image acquisition part；6.1 second supports；7 rotating shafts；8 wheel hubs。
A kind of hub detection device, including base plate 1 riser 2 that be connected fixing with base plate 1, described riser is provided with through hub centre hole, and the rotating shaft 7 that can rotate, described riser 2 is additionally provided with the slide block 3.2 that can slide up and down, being fixed with motor 3 on described slide block 3.2, motor output shaft 3.1 is provided with friction roller 4, and described friction roller 4 can contact the outer rim of wheel hub 8 and drive wheel hub to rotate；Described detecting device also includes the first image acquisition part 5 that can gather outer rim image and the second image acquisition part 6 that can gather interior wheel rim image。First image acquisition part 5 is fixed on described riser by the first support 5.1；Described second image acquisition part 6 is hinged on base plate by the second support 6.1, and described second support 6.1 is " L " type support, and one end of described second support 6.1 is fixing with the second image acquisition part to be connected, and the other end is hinged on described base plate。In order to ensure the quality of image acquisition, the first image acquisition part 5 and the second image acquisition part 6 are CCD camera。The part that rotating shaft 7 contacts with wheel hub 8 centre bore is provided with rubber sleeve, is so more conducive to be fixed in rotating shaft by centre bore, riser can arrange bearing, and rotating shaft rotates in bearing, wheel hub and bearing synchronous rotary。Friction roller is rubber friction roller, so can increasing friction force, thus be unlikely to skid, make friction roller 4 drive wheel hub 8 to rotate better。Detecting device also includes the controller being connected with motor the 3, first image acquisition part the 5, second image acquisition part 6。
Concrete use procedure is as follows: during beginning, as in figure 2 it is shown, turned down by motor, by the major axis horizontal positioned of L-type the second support, the centre bore of tested wheel hub is enclosed within the part with rubber sleeve of rotating shaft 7, and rotating shaft is fixed。It follows that as it is shown in figure 1, motor is raised, make contact outer rim surface, friction roller surface, the second support rotated, enables the second image acquisition part to gather interior wheel rim image。During test, friction roller drives hub rotation one week, and first and second image acquisition part realizes the image acquisition to circumferencial direction whole inside and outside wheel hub, the result according to the image procossing gathered, it is judged that either with or without crackle, flaw etc. on wheel hub, thus judging that whether wheel hub is qualified。
Although this utility model has been illustrated with regard to preferred implementation and has described, it is understood by those skilled in the art that without departing from claim limited range of the present utility model, it is possible to this utility model is carried out variations and modifications。
