一种提高装配效率的工艺流程优化设计

Optimization Design of a Technological Process of Improving Assembly Efficiency

工艺流程是工艺路线规划的核心内容,其设计的合理性直接影响装配工艺的可行性和装配性。弹翼结构由于其装配难度大,测试时间长,成为制约弹箭产品装配进度的重要因素之一。通过对弹箭产品的设计需求和结构特性进行分析发现,弹翼结构并非通电筛选考核的必要条件,且其与产品的结构连接可拆解。依据产品模块化的设计理念,将弹翼结构作为一个装配单元从总装流程中提炼出来先行装配。工艺流程优化后,弹翼结构装配和舱段装配可同时开展,极大降低了后续总装节点的压力。该工艺流程优化方法可有效提高产品的装配效率;同时,先行装配的思路为弹箭产品的工艺设计提供了一种新的方法,在工艺流程设计中发掘可独立成模块的组件进行提前装配,可提升装配工艺水平。

Technological process was the core content of process route planning,its design rationality directly impacted the feasibility and assembly of the process.Because of difficulty in assembling and long test time of the missile wing structure,it became one of the important factors which restricted the assembly progress of missile products.Through the analysis of the design requirements and structural characteristics of missile products,it was found that the missile wing structure was not a necessary condition for power-on screening assessment,and its structural connection with the product could be disassembled.According to the modular design concept of the product,the missile wing structure was extracted from the final assembly process as a unit for pre-assemble.After process optimization,the assembly of the missile wing structure and the assembly of the cabin section could be carried out at the same time,which greatly reduced the pressure on the subsequent final assembly nodes.The technological process optimization method can effectively improve the assembly efficiency of the product.At the same time,the idea of first assembly provided a new method for the process design of the missile products.In the technological process design,the components that can be independently modularized could be assembled in advance to improve the level of assembly process.
