摘要
数控机床夹具是数控加工中最重要的构件之一,其装夹效果和效率对产品的加工质量和生产效率有重大影响。为了提高产品的加工质量和降低生产成本,融合约束理论TOC和发明问题解决理论TRIZ并将其应用于自动夹具的优化设计当中。首先应用TOC对夹具的问题进行综合分析,找出导致自动夹具装夹效果不佳的7个关键因素;然后借助TRIZ理论对问题进行求解,形成12种设计方案;最后运用理想化水平计算公式对12种方案进行理想化评价,通过6种较优方案的组合优化,得到最终的具有自清洁能力的数控机床自动夹具设计方案。并通过仿真验证了该设计方案的可行性。通过TOC/TRIZ理论对数控机床夹具进行优化设计,为相关装置的设计提供理论基础和实践案例。
The fixture of CNC machine tools is one of the most important components in CNC machining.Its clamping effect and efficiency have a significant impact on the machining quality and production efficiency of products.In order to improve the machining quality of products and reduce production costs,the constraints theory TOC and the inventive problem solving theory TRIZ were integrated and applied to the optimized design of automatic fixtures.TOC was applied to comprehensively analyze the problems of the fixture,and seven key factors causing poor clamping effect of the automatic fixture were identified.Then TRIZ theory was used to solve the problems,and twelve design schemes were formed.Finally,the ideality level calculation formula was used to evaluate the ideality of the twelve schemes.Through the combinatorial optimization of six relatively optimal schemes,the final design scheme of the automatic fixture with self-cleaning ability was obtained.The feasibility of the design scheme was verified by simulation.The optimized design of the CNC machine tool fixture through TOC/TRIZ theory provides a theoretical basis and practical case for the design of related devices.
