Abstract: In order to improve the work efficiency of automatic piston lines, the potential failure modes and failure mechanisms of the piston machining production are analyzed. The application of corresponding error-prevention and confusion-prevention technology are analyzed, including visual image error-prevention and confusion-prevention, fixture air tightness detection-prevention, fixture rigid interference error-prevention, and tool breakage detection error-prevention technology in different processes of the production line. The research results show that in terms of piston process design, error-prevention and confusion-prevention technology can prevent the generation of failure mechanisms or failure modes; in terms of inspection and control of the machining process error-prevention and confusion-prevention technology can eliminate the outflow of piston failure parts, the error-prevention and mixing-prevention technology improve the production efficiency and product quality of the piston machining automatic lines.
