Abstract

The invention discloses machining detection equipment for an automobile hub. The machining detection equipment comprises an image acquisition module, a preprocessing module, an image segmentation processing module, an image comparison module and a detection module. Based on acquisition and preprocessing of the images of the hub in multiple transmission states in the transmission process, the reference value of the images is higher, the comparison image constructed after preprocessing is compared with the original image in a partitioned mode, the accuracy of the whole comparison process is improved, and meanwhile, the accuracy of the whole comparison process is improved; and the effectiveness of overall judgment can be better improved. On the basis, judgment of a single image and comprehensive analysis of a plurality of images are carried out after comparison, so that detection of the quality of the automobile hub is effectively realized.

Description

technical field [0001] The invention relates to the field of real-time detection equipment in the production process of automobile wheel hubs, in particular to a processing detection equipment for automobile wheel hubs. Background technique [0002] The automobile wheel hub is the part where the axle is installed in the center of the wheel. Once it is die-casted during the processing process, it needs to be processed in subsequent steps. Therefore, in the actual production process, it is often necessary to carry out preliminary inspection after its die-casting, so as to avoid the defective products with obvious defects from entering the next process, resulting in the waste of resources in the production process and the increase in the difficulty of recycling. [0003] The detection in the existing production process is generally in the state of assembly line processing, so it is often manually detected and judged by naked eyes. This detection method is not only inefficient, ...
