【摘要】：當下,作為家具生產(chǎn)工具的木工機床產(chǎn)品其加工能力要求越來越高。在國外,多用途、自動化程度高的數(shù)控木材加工中心已經(jīng)取代了不少老式的低端的木工機床,在家具制造行業(yè)中充分體現(xiàn)數(shù)控木材加工中心自動化、多功能、柔性化的優(yōu)點。目前,國內(nèi)部分木工機械的龍頭企業(yè)也開始著手研發(fā)擁有自主知識產(chǎn)權(quán)的數(shù)控木材加工中心,但是國產(chǎn)的數(shù)控木材加工中心多數(shù)為基型產(chǎn)品,尚未形成系列化的產(chǎn)品,因此,其發(fā)展?jié)摿薮?市場廣闊,有不少企業(yè)和單位對這種新產(chǎn)品進行改形設(shè)計和自適應(yīng)的設(shè)計。其中,改形設(shè)計很大程度上屬于重復(fù)勞動,所以需要一種手段去提高設(shè)計效率,減少重復(fù)勞動。 本文以東莞南興家具裝備制造有限公司的一款數(shù)控木材加工中心為對象,結(jié)合計算機輔助設(shè)計理論及思想,解決Solidworks二次開發(fā)的問題,解決產(chǎn)品設(shè)計知識的表達問題,進而開發(fā)出一款利用參數(shù)化技術(shù)實現(xiàn)基于產(chǎn)品設(shè)計知識的自動建模、裝配系統(tǒng),滿足產(chǎn)品改形設(shè)計需求。其積極意義表現(xiàn)為有利于產(chǎn)品設(shè)計知識的傳承和培訓,降低設(shè)計人員門檻；有利于使設(shè)計人員從重復(fù)勞動中解放出來,把更多精力投放于其他創(chuàng)新設(shè)計；有利于快速響應(yīng)客戶需求,實現(xiàn)企業(yè)和客戶在利益上雙贏。本論文的主要研究工作如下： 首先介紹了通用CAD軟件的二次開發(fā)技術(shù),并且著重研究了Solidworks的二次開發(fā)技術(shù)與方法,對建模和裝配進行歸納,通過掌握參數(shù)化技術(shù)的理論基礎(chǔ),研究了產(chǎn)品參數(shù)化設(shè)計的實現(xiàn)過程,并作了詳細介紹。 然后,研究數(shù)控木材加工中心的設(shè)計知識主要是對木材加工中心產(chǎn)品功能原理、結(jié)構(gòu)特點、設(shè)計流程進行論述。以產(chǎn)品的結(jié)構(gòu)件為開發(fā)對象、Solidworks2011三維建模軟件為開發(fā)平臺、Visual Basic6.0為開發(fā)工具,Access2003為參數(shù)儲存的數(shù)據(jù)庫,開發(fā)了木材加工中心的方案搜索系統(tǒng)和參數(shù)化設(shè)計系統(tǒng)。 最后,通過介紹系統(tǒng)的操作和應(yīng)用功能論證了系統(tǒng)的可行性,該系統(tǒng)具有較合符行業(yè)設(shè)計人員習慣的操作的界面,功能全面,能夠大大減少設(shè)計的工作量,提高產(chǎn)品設(shè)計效率,快速響應(yīng)客戶的設(shè)計要求。
[Abstract]:At present, woodworking machine tools as furniture production tools require higher and higher processing capacity. In foreign countries, numerical control woodworking centers with multi-purpose and high degree of automation have replaced many old-fashioned low-end woodworking machines, which fully embody the advantages of automation, multi-function and flexibility of NC woodworking centers in the furniture manufacturing industry. At present, some leading enterprises of woodworking machinery in China have also begun to develop CNC wood processing centers with independent intellectual property rights. However, most of the domestic CNC wood processing centers are basic products and have not yet formed a series of products, so, Its development potential is huge, the market is broad, there are many enterprises and units to this new product to modify the design and adaptive design. Among them, the modified design belongs to repetitive work to a large extent, so a method is needed to improve the design efficiency and reduce the repetitive work. This paper takes a numerical control wood processing center of Dongguan Nanxing Furniture and equipment Manufacturing Co., Ltd. as an object, combining with the theory and idea of computer aided design, to solve the problem of secondary development of Solidworks, and to solve the problem of expressing the knowledge of product design. Then, an automatic modeling and assembly system based on product design knowledge is developed by using parameterized technology to meet the needs of product shape modification design. Its positive significance is that it is beneficial to the inheritance and training of product design knowledge, to lowering the threshold of designers, to freeing designers from repeated work, and to putting more energy into other innovative designs. It is beneficial to the quick response to the customer's demand and to the win-win situation between the enterprise and the customer. The main research work of this thesis is as follows: firstly, the secondary development technology of general CAD software is introduced, and the secondary development technology and method of Solidworks are emphatically studied, and the modeling and assembly are summarized. Through mastering the theoretical foundation of parameterization technology, the realization process of product parameterized design is studied and introduced in detail. Then, the research on the design knowledge of NC wood processing center is mainly to discuss the function principle, structure characteristics and design flow of wood processing center product. Taking Solidworks2011 3D modeling software as the development platform and visual Basic6.0 as the development tool, the paper develops a scheme search system and a parametric design system for wood processing center by taking the structure of the product as the development object, and using Visual Basic6.0 as the development tool and access 2003 as the parameter storage database. Finally, the feasibility of the system is demonstrated by introducing the operation and application functions of the system. The system has a more suitable interface for the operation of designers in the industry, and has a comprehensive function, which can greatly reduce the workload of design and improve the efficiency of product design. Quick response to customer design requirements.
