Structure Analysis And Optimization Of Heterotypic Stone Processing Center Based On The Theory Of Reconfiguration

The main processing method of the heterotypic stone products is small batch production due to its characteristics including individuation, diversification and artisry, which requires the processing equipment of heterotypic stone has the characteristics such as large range of processing, easy operation and diversification of the processing combination. Recently, although the equipment of stone industry can achieve the processing of heterotypic stone products, the high equipment cost can not satisfy the efficient and economy of production requirement of the enterprise. Therefore, it has a very important research significance and application value to study the multi-function and low equipment cost of heterotypic stone processing based on the characteristics of the heterotypic stone products and development needs of stone industry.(1)Based on the heterotypic stone turn-milling center HTM50200 and the guidance of the theory of generative design, this paper has carried on the functional analysis of the heterotypic stone turn-milling center in view of maching process and tool path. The analysis based on the generative theory on the types of information resources of the tool and processing surface, information resources database of the tool and surface have been carried on in this paper.(2)Turning processing refers to horizontal five-axis linkage machining including the movement of X, Y, Z axis and the turn of B, C axis; Engraving and milling processing refers to vertical four axis linkage processing including the movement of X, Y, Z axis and turn of B axis.(3)The development of virtual prototype of the reconfigurable heterotypic stone maching center by 3D design software has beem carried on in this paper which analysis the force and constraint condition of beam and lathe bed in actual maching process. The lectotype design for the main structural component of maching center including upright, beam, lathe system, rotating table and servofeed system has been proceed and described the technical parameters, material selection and physical design of the maching center. Statics and dynamics analysis on the core component of the maching center by Ansys Workbench targetly which guaranteed the rationality of the machine structure and find out the weak link of the machine, reasonable improvement was put forward in this paper.(4)Analysis of structural topology optimization calculation on beam reinforcement plate structure by programming language in MATLAB and optimized analysis on the beam deoxidization hole by topological opt module in Ansys have been accomplished that concluded new type of beam structure. Analysis result shows that the new scheme not only reduced the weight, but also improved the static and dynamic characteristics of beam compared with the original plan, the new scheme has a fantastic optimization and laid a theoretical basis for practical production.
