The invention discloses a method and a system for detecting surface defects of a sintered tumbling grinding block. The system comprises a grinding block surface image acquisition unit composed of a sampling disc, a single-chip microcomputer, a stepping motor and a digital microscope; a grinding block surface defect detection unit composed of an image enhancement method, a threshold segmentation method, a defect boundary statistics method and a defect extraction method; and a display unit which utilizes an upper computer interface to realize system setting, image acquisition, image detection and visual presentation and control of a detection conclusion according to the grinding block surface defect detection method and system. According to the invention, the surface images of a grinding block can be continuously acquired, the surface defects of the grinding block are digitally analyzed, and the traditional manual detection can be replaced. The subjectivity of manual detection and judgment is eliminated, and the influence of inaccurate detection and evaluation on the use effect of a tumbling grinding block is reduced.
Description
technical field [0001] The invention relates to the field of detection technology and devices, in particular to a method and system for detecting surface defects of sintered tumbling and polishing abrasive blocks. Background technique [0002] At present, the preparation quality of existing sintered tumbling abrasive blocks in China is not high, the quality of different batches of tumbling abrasive blocks is unstable, the preparation process of tumbling abrasive blocks is simple, the parameter control is unstable, and the degree of production intelligence is low, resulting in The high wear rate of the tumbling grinding block and the low impact strength lead to abnormal breakage, etc., mainly manifested in the presence of defects such as black centers, impurities, and unevenness on the surface of the tumbling grinding block. These problems directly affect the processing effect, processing efficiency and economical use. Therefore, rapid and accurate detection of surface defect...
