【摘要】：随着木材制品的市场需求不断增加,科学技术和机械制造技术的不断进步,由于传统的实木加工机器自动化程度低、加工精度差、加工效率不高,传统的实木加工机器逐渐被自动化实木加工机器代替,因此本文对实木自动加工机床展开设计、分析与研究。本文首先阐述项目研究目的与意义,综合比较国内外实木加工机床的研究技术,在查阅大量文献基础上,利用计算机辅助设计(CAD)、虚拟制造技术(VM)和计算机辅助工程技术(CAE)等现代设计技术,设计实木方料桦眼、铣槽及钻孔柔性自动加工机床,主要应用于实木家具制造工艺上的桦眼、钻孔及铣槽上。论文主要工作包括:(1)具体比较国内外实木自动化加工机床的设计方法和工艺要求,确定机床的主要技术参数和总体布局:采用“一”字型的机床结构方案,确定传动方式与布置形式;机架结构采用空心型方钢焊接而成,设计实木自动化机床各个加工系统的机械框架结构;对实木自动加工机床的进料系统、加工系统、出料系统等功能部件进行详细、精准的计算,并完成这些零部件的设计与校核。(2)采用solidworks软件对实木自动加工机床的机械结构进行三维建模,并通过虚拟装配仿真,建立实木自动化加工机床虚拟样机,为后期实木自动加工机床静态分析、模态分析打下基础。(3)利用有限元法对实木自动加工机床关键部件进行结构性能分析,采用ANSYS有限元分析软件进行模型前后处理,仿真模型边界条件、载荷工况等,结合ANSYS求解器,完成实木自动加工机床关键部件的静态分析、模态分析。然后分析实木自动加工机床机架、床身等部件的应力、位移变形数据、固有频率和振型。实木方料桦眼、铣槽及钻孔柔性自动加工机床提高实木加工的效率、保证木制品的加工质量、降低企业用工数量和工人劳动强度、降低实木家具制造成本。对我国木材加工行业的发展有一定的促进和借鉴意义。
[Abstract]:With the increasing market demand for wood products and the continuous progress of science and technology and mechanical manufacturing technology, because of the low degree of automation of traditional solid wood processing machines, processing accuracy is poor, processing efficiency is not high, The traditional solid wood processing machine is gradually replaced by the automatic solid wood processing machine, so the design, analysis and research of the solid wood automatic processing machine are carried out in this paper. In this paper, the purpose and significance of project research are first expounded, and the research technology of solid wood processing machine tools at home and abroad is comprehensively compared, on the basis of consulting a large number of documents, Using modern design techniques such as computer aided design (CAD), virtual manufacturing (VM) and computer aided engineering (CAE) to design solid wood birch, milling slot and drilling flexible automatic machining machine tools, which are mainly used in the manufacture process of solid wood furniture. Drill holes and milling slots. The main work of this paper includes: (1) to compare the design methods and technological requirements of domestic and foreign automatic woodworking machine tools, and to determine the main technical parameters and overall layout of the machine tools: the structural scheme of machine tools with "one" shape is adopted. The frame structure is made of hollow square steel, the mechanical frame structure of each machining system of solid wood automatic machine tool is designed, the feeding system and machining system of solid wood automatic machine tool are designed, The material discharging system and other functional components are calculated in detail and precision, and the design and verification of these parts are completed. The mechanical structure of the machine tool is modeled by solidworks software, and the simulation of virtual assembly is carried out. The virtual prototype of solid wood automatic machining machine tool is established, which lays a foundation for static analysis and modal analysis of solid wood automatic machining machine tool in the later stage. The finite element method is used to analyze the structure and performance of key parts of solid wood automatic machining machine tool. The ANSYS finite element analysis software is used to deal with the model before and after, the boundary condition of the model is simulated, the load condition and so on, combined with the ANSYS solver, the static analysis and modal analysis of the key parts of the machine tool for automatic machining of solid wood are completed. Then, the data of stress and displacement deformation, natural frequency and vibration mode of the machine frame and bed are analyzed. The machining efficiency of solid wood is improved, the processing quality of wood products is guaranteed, the number of workers and the labor intensity of workers are reduced, and the manufacturing cost of solid wood furniture is reduced. It is of great significance to promote the development of wood processing industry in China.
