Problems solved by technology

This detection method is not only labor-intensive for workers, but also the plug gauge is easy to wear after long-term use, and the measurement results are also easily affected by human factors.
If a contact detection similar to a three-coordinate measuring machine is used, not only the detection time cannot meet the production cycle, but also the detection environment cannot meet the requirements.

Embodiment 1

[0031] Such as figure 1 As shown, the embodiment of the present invention provides an on-line detection device for the hole size of the automobile hub cover, including a gantry 1, the top of the gantry 1 is provided with a downwardly extending installation frame 2, and an industrial camera 3 is installed on the installation frame 2 , the lens of the industrial camera 3 is connected to the telecentric lens 5, the telecentric lens 5 is installed on the mounting frame 2 through the lens mounting plate 4, the telecentric lens 5 is a standard component, and can be purchased and used by those skilled in the art. Obtain an image with a low distortion rate, improve the accuracy of size detection, and adapt to the size and structure of different hubs; the gantry 1 is provided with a mounting seat 6, and the mounting seat 6 is provided with a hub support frame 7, and the industrial camera 3 faces the hub support frame 7 , during detection, the hub is placed on the hub support frame 7, a...

Embodiment 2

[0037] The embodiment of the present invention provides an on-line detection device for the hole size of the automobile hub cover. Its structure is basically the same as that of the embodiment 1. The difference is that on the basis of the embodiment 1, the following improvements are made to further improve its performance :

[0038] Mounting seat 6 is provided with linear drive mechanism, and linear drive mechanism connects wheel hub support frame 7, and here, linear drive mechanism is preferably electric cylinder 17, and the piston rod of electric cylinder 17 connects wheel hub support frame 7, and the cylinder block of electric cylinder 17 is fixed. Installed on the mounting base 6 , of course, those skilled in the art can also choose to use air cylinders or hydraulic cylinders, which will not be listed one by one here.

[0039] Because the linear drive mechanism is set to drive the hub support frame 7, when the wheels of different sizes and specifications are placed on the ...

Embodiment 3

[0041]The embodiment of the present invention provides an on-line detection device for the hole size of the automobile hub cover, the structure of which is basically the same as that of embodiment 2, the difference is that

[0042] A centering mechanism for aligning the center of the hub with the center of the hub support frame 7 is provided on the mounting base 6 . The centering mechanism includes two sliding beams 18 that are slidably installed on both sides of the hub support frame 7 through linear guide rails, and a double-headed screw 20 driven by a power device is installed on the mounting seat 6. The power device is preferably a servo motor. The screw threads at both ends of the screw 20 have opposite helical directions, and each sliding beam 18 is fixedly equipped with a nut that is compatible with the double-ended screw 20, so that when the double-ended screw 20 rotates, the two sliding beams 18 can be synchronously facing or opposite directions. Sliding can push the ...

Description

technical field [0001] The embodiment of the present invention relates to the technical field of auto parts testing equipment, in particular to an on-line testing equipment for the hole size of an automobile hub cover. Background technique [0002] The hub cover of the automobile is assembled on the hole of the hub cover of the automobile, and the cover not only plays a waterproof role but also has a certain aesthetic effect. The dimensional accuracy of the cover hole of the wheel hub directly affects the fit between the hub and the cover, so it will affect the safety and appearance of the vehicle to a certain extent. In recent years, with the upgrading of domestic automobile consumption, users have become more and more demanding on the quality of automobile hub cover holes. In order to ensure the manufacturing accuracy of the hub cover hole, it is necessary to conduct a full inspection of its size on the assembly line. [0003] The existing method for full inspection of t...
