【摘要】：五金件作為機械領(lǐng)域中重要一部分,已經(jīng)被廣泛使用。然而,國內(nèi)五金件設(shè)計采用傳統(tǒng)設(shè)計方法,在繪圖方面耗費大量精力,而且很難保證模型質(zhì)量。隨著國內(nèi)計算機輔助設(shè)計不斷成熟,計算機輔助技術(shù)已經(jīng)廣泛應(yīng)用到各種機械行業(yè)。國內(nèi)外已經(jīng)展開了在三維環(huán)境中模塊化、變量化、標(biāo)準(zhǔn)化研究,但是還沒有出現(xiàn)基于三維環(huán)境下機械類五金件參數(shù)化研究。 針對以上存在的問題,本課題研究了五金件計算機輔助設(shè)計技術(shù),并從以下幾個方面完成工作： a.本文從五金件分類入手,提出將五金件分為標(biāo)準(zhǔn)件與非標(biāo)準(zhǔn)件方法；并從非標(biāo)準(zhǔn)件中選取浮動球閥、閘閥作為研究對象,研究了閥類設(shè)計方法,提出設(shè)計流程。 b.探討了五金件專用CAD系統(tǒng)架構(gòu)；分析了五金件系統(tǒng)的需求；依據(jù)軟件工程設(shè)計原則,制定開發(fā)方案；擬定了三維軟件平臺、開發(fā)語言、數(shù)據(jù)庫等。 c.研究了Solidworks2012二次開發(fā)技術(shù),訪問數(shù)據(jù)庫基本方法；提出應(yīng)用多種參數(shù)化方法解決五金件參數(shù)化問題；五金件產(chǎn)品數(shù)據(jù)模型庫創(chuàng)建；五金件模板創(chuàng)建的關(guān)鍵技術(shù)。 d.完成各個模塊的創(chuàng)建及界面設(shè)計,并解決了模塊之間數(shù)據(jù)的訪問。 基于以上工作,在本文中作者應(yīng)用Visual Basic6.0企業(yè)版軟件對Solidworks2012軟件進(jìn)行開發(fā)。此系統(tǒng)擁有五金件參數(shù)化設(shè)計功能、球閥、閘閥結(jié)構(gòu)設(shè)計功能、自動計算、校核,生成設(shè)計文檔、三維零件模型以及二維工程圖、系統(tǒng)參數(shù)化模板擴(kuò)展等,進(jìn)而成為機械五金件領(lǐng)域計算機輔助設(shè)計應(yīng)用實例。
[Abstract]:As an important part of mechanical field, hardware has been widely used. However, the traditional design method is used in hardware design in China, which consumes a lot of energy in drawing, and it is difficult to guarantee the quality of the model. With the maturity of CAD in China, CAD has been widely used in various mechanical industries. Research on modularization, variation and standardization in 3D environment has been carried out at home and abroad, but there is no parameterized research on mechanical hardware based on 3D environment. In view of the above problems, this paper studies the hardware computer aided design technology, and completes the work from the following aspects: a. Starting with the classification of hardware, this paper puts forward the method of dividing hardware into standard parts and non-standard parts, and selects floating ball valve and gate valve from non-standard parts as the research object, studies the design method of valve class and puts forward the design flow. b. This paper discusses the architecture of hardware CAD system, analyzes the requirements of hardware system, formulates the development scheme according to the principle of software engineering design, and draws up the 3D software platform, development language, database and so on. c. The second development technology of Solidworks2012 and the basic method of accessing database are studied, and the key technologies of hardware parameterization are put forward, such as the creation of hardware product data model base and the creation of hardware template. d. Complete the creation of each module and interface design, and solve the data access between modules. Based on the above work, the author uses Visual Basic6.0 Enterprise Edition software to develop Solidworks2012 software. This system has hardware parameterized design function, ball valve, gate valve structure design function, automatic calculation, check, generate design document, 3D part model and 2D engineering drawing, system parameterized template extension, etc. Then it becomes the application example of computer aided design in the field of mechanical hardware.
