Design And Study On The Reconfigurable Design And Structure Optimization Of The Multi-axis Linkage Equipment Based On Curved Surface Parts

The economic competition and product demand causing by the global economic integration appears increasingly the trend of personalization, It results in diversity of products and market life cycle continuously shortening, customer demand for manufacturing enterprise’s production, product variety and production is also unpredictable. How to exist in the current environment make today’s manufacturing system to quickly and economically in response to changing in production requirements is the manufacturing industry faces a huge difficulties and challenges. Reconfigurable manufacturing systems could have more advantages. For a given range of production requirements to provide custom, through configurating suitable function of the machine tool when requirements change, based on the maximum use of existing resources, with the manufacturing system structure configuration and composition unit of restructuring or updating quickly, economically change to a new manufacturing system in respond to new requirements to custom.By the analysis of problems existing in current machine tools production mode, the system integrated framework is determined. The reconfigurable multi-axial linkage equipment consists of device layer, and is supported by many enabling technologies. The paper takes application technologies as study objects.The product family process indentifying and classifying is based on position tolerance algorithm and K-means algorithm. The processes that can be completed on the same equipment are allocated in the same process combination. Then, the optimal combination of process family is obtained by merging and sorting between process combinations. Through the processing movement analysis of each process combination, the basic functions needed by reconfigurable multi-axial linkage equipment are determined. Based on modular design method, the reconfigurable multi-axial linkage equipment is divided into several mechanical modules. The paper completed the preliminary structural design of each sub-module, and obtained the configuration diagram of reconfigurable multi-axial linkage equipment by combining each module. The five-dimensional model of reconfigurable multi-axial linkage equipment is finally constructed with Solidworks. In this paper, by studying the the process of classification and identification of typical curved parts, the basic function of multi-axis linkage device, kinematics modeling to determine the basic function of the reconfigurable multi-axis linkage equipment and the basic structure type. For certain types of five-axis linkage machine tool module partition, establish basic module library, by selecting the relevant modules in module library established several multi-axial linkage equipment structure configuration options are available, according to the given procedure and establish multi-axial linkage device module library for reconfigurable multi-axis linkage equipment in mechanical structure design, finally completed based on the curved surface parts process of reconfigurable multi-axis linkage equipment set up. When making multi-axis linkage device structure optimization, use the static, dynamic analysis, dynamic analysis in problem give full consideration to the joint surface, and established the dynamic model of rolling linear guide pair, enhance the accuracy of the modal analysis, improved the weak links of multi-axis linkage device, improves the static and dynamic characteristics of the multi-axis linkage equipment.
