| Remanufacturing is an important means of reusing resources and creating a conservation-minded society, and the assembly process is the last step of production for remanufactured products. The production process control has direct influence on the utilization of the remanufacturing resources. This article is precisely aimed at this issue, mainly studying on the quality control of the assembly process for remanufactured engine; it proposes the quality control methods and support system research in the key process of remanufactured engine assembly. This article mainly includes the following parts:Firstly, the remanufacturing process flow and processing technology for remanufactured engine are systematically elaborated, and the assembling process and technological process of remanufactured engine are sorted out. Then this paper analyzes systematically the key assembly quality control points in the assembly process of remanufactured engine and quality control model.Secondly, this paper takes quality control for main bearing bolt cap tightening process and static torque detection process of remanufacturing engine as the research object, and elaborates the purpose and significance of tightening torque control. Then the control method for the main bearing cap bolt tightening torque based on knowledge prediction is built. And its the feasibility and effectiveness are verified through the algorithm case.Thirdly, for remanufacturing engine assembly process, taking the quality control informatization platform in the assembly process of some remanufacturing engine company as the research object, this paper analyzes the system requirements aiming at solving the existing problems of this company. From the angle of configurable, extensible, and visual system, and with.NET development platform and SQL database technology applied, this article builds the quality control support system for remanufactured engine assembly process to realize the practical application of related theories. |
