Abstract: As a key component of automobile engine, the quality control of the connecting rod in the production process is an important prerequisite for engine quality assurance. This paper mainly studies the application of the quality assurance method of anti-error and anti-mixing in the processing of connecting rod production, including the implementation cases of mechanical error-proofing mechanism, electrical anti-error measures, anti-error and anti-mixing visual detection, and anti-error air tightness detection. To the greatest extent, it eliminates the processing sequence leakage and machine type mixing caused by human and machine factors, improves the quality assurance ability of connecting rod processing, and also provides anti-error and anti-mixing ideas and implementation methods for the production and manufacturing process of related parts in the automobile industry.
