Problems solved by technology

Therefore, when this method is used for detection, the labor intensity of the workers is relatively high, and it is difficult to detect the surface defects of the car hub. In addition, because the speed of the workers is not easy to control when turning the car hub, these factors will affect the detection accuracy.
In the existing technology, the detection method is single, and the hub stays at the detection position for a long time, which is not conducive to speeding up production
Due to the complex structure of the automobile hub, the manual detection efficiency is low, the workload is heavy, and fatigue is easy to occur, it is difficult to meet the mass production requirements of the hub with this method.

Abstract

The invention relates to an automatic hub surface defect detection device which comprises a to-be-detected hub conveying unit, a hub outer side defect detection unit, a hub inner side defect detection unit and a detected hub conveying unit. Hubs are conveyed to the hub outer side defect detection unit through the to-be-detected hub conveying unit, and hub outer side defect detection and marking tasks are completed. The hub is further conveyed to a hub inner side defect detection unit to complete hub inner side defect detection and marking tasks; and finally, the hub is conveyed to a detected hub conveying unit, and a qualified product and defective product sorting task is completed. According to the hub surface defect automatic detection device, region division is carried out on the hub based on the characteristics of a hub rotating body, the hub surface defect automatic detection device is provided according to the division result, full automation of hub inner and outer surface defect detection and marking is achieved through a region division detection mode, the hub defect detection and marking efficiency is effectively improved, and the hub surface defect automatic detection device has good practical application value.

Description

technical field [0001] The invention relates to the technical field of automobile wheel hub surface defect detection, in particular to an automatic detection device for wheel hub surface defects. Background technique [0002] Before the wheel hub is an important component of automobile manufacturing, the quality of the wheel hub affects the driving quality of the car. The machining accuracy of the vehicle wheel hub is directly related to the safety and comfort of the vehicle at high speed. The surface accuracy of the wheel hub is an important parameter for evaluating the quality of the wheel hub. And with the development of the automobile industry, the existing wheel hub not only needs to prevent defects in structure, but also has no defects such as scratches on the surface of the wheel hub. During the processing and production of wheel hubs, it is inevitable that a small number of wheel hubs have surface defects, such as cracking, peeling paint or other obvious surface qual...
