【摘要】：離心通風機是在國民經(jīng)濟各領域中廣泛應用的一種通用機械,產(chǎn)品已經(jīng)形成多個系列,設計和生產(chǎn)技術也在不斷增強和改進。隨著市場競爭的日益激烈化,如何提高產(chǎn)品設計效率、快速響應用戶的設計需求,降低成本,對于提高企業(yè)效益和產(chǎn)品的市場競爭力具有重要的意義。目前在機械設計主流的手段仍停留在二維階段,其存在設計過程不直觀、工作量大、設計中的錯誤不易發(fā)現(xiàn)等缺陷,因而采用三維CAD技術進行產(chǎn)品的設計是必然的發(fā)展趨勢。目前在離心通風機的設計過程中采用三維軟件進行實體造型、出效果圖等方面已經(jīng)得到了一定的應用,但是針對離心通風機設計的計算機輔助設計的系統(tǒng)的研究尚處于探索階段。本文開發(fā)的離心通風機CAD系統(tǒng),提高了離心通風機選型和變型設計的效率,縮短了設計周期,提高了離心通風機三維參數(shù)化建模和向工程圖紙轉(zhuǎn)換的效率以及準確度,實現(xiàn)了離心通風機快速、高效、準確的設計。 離心通風機的設計制造己形成標準系列化產(chǎn)品,相同系列的風機之間的零部件結(jié)構(gòu)和功能均相似,本文以系列化離心通風機為對象,以三維CAD軟件SolidWorks為平臺,結(jié)合Access數(shù)據(jù)庫技術,采用面向?qū)ο蟮腣isual Basic 6.0語言,對SolidWorks進行二次開發(fā),建立了離心通風機的CAD系統(tǒng)。系統(tǒng)分為選型與變型設計模塊和參數(shù)化設計模塊兩大部分,主要研究了離心通風機的快速選型、相似設計與氣動力設計和基于SolidWorks進行參數(shù)化設計的關鍵技術,建立了有關離心通風機的各種模型庫、數(shù)據(jù)庫以及標準件庫等。 離心通風機CAD系統(tǒng)的功能主要包括以下幾個方面：(1)對離心通風機快速選型；(2)當沒有選到合適風機型號時,通過變型設計模塊可以快速設計出滿足要求的風機；(3)實現(xiàn)參數(shù)化建模和參數(shù)化裝配；(4)自動生成工程圖,并對其進行調(diào)整,包括視圖位置調(diào)整、視圖比例調(diào)整、尺寸位置調(diào)整、明細表自動生成與調(diào)整、技術要求預添加等方面,實現(xiàn)生成的圖紙能夠完全滿足企業(yè)生產(chǎn)的要求
[Abstract]:Centrifugal ventilator is a kind of universal machinery widely used in various fields of national economy. Many series of products have been formed and the design and production technology has been continuously enhanced and improved. With the increasingly fierce market competition, how to improve the efficiency of product design, quickly respond to the design needs of users, reduce costs, to improve the efficiency of enterprises and the market competitiveness of products has an important significance. At present, the mainstream method of mechanical design is still in the two-dimensional stage, which has some defects, such as the design process is not intuitive, the workload is large, the mistakes in the design are not easy to be found, so it is an inevitable development trend to adopt the three-dimensional CAD technology to design the products. At present, in the design process of centrifugal fan, 3D software is used for solid modeling, and the effect diagram has been applied to some extent. However, the research of CAD system for centrifugal fan design is still in the exploratory stage. The CAD system of centrifugal fan developed in this paper improves the efficiency of centrifugal fan selection and variant design, shortens the design cycle, and improves the efficiency and accuracy of 3D parametric modeling and conversion to engineering drawings of centrifugal fan. The centrifugal fan is designed quickly, efficiently and accurately. The design and manufacture of centrifugal fans have formed standard serialized products, and the components and functions of the same series of fans are similar. This paper takes serialized centrifugal ventilators as an object and takes 3D CAD software SolidWorks as the platform. Combined with Access database technology, the secondary development of SolidWorks is carried out by using object-oriented Visual basic 6.0 language, and the CAD system of centrifugal fan is established. The system is divided into two parts: type selection and variant design module and parametric design module. The key technologies of centrifugal fan selection, similar design and aerodynamic design and parameterized design based on SolidWorks are studied. The model base, database and standard parts database of centrifugal fan are established. The function of centrifugal fan CAD system mainly includes the following several aspects: 1) when the appropriate fan model is not selected, the fan can be designed quickly to meet the requirements through the variant design module. (3) realize parameterized modeling and parameterized assembly to generate engineering drawing automatically, and adjust it, including view position adjustment, view proportion adjustment, dimension position adjustment, detail list automatic generation and adjustment, technical requirement pre-addition and so on. The generated drawings can fully meet the requirements of enterprise production.
