【摘要】：夾具設計是集知識、經(jīng)驗決策、計算、繪圖于一體的結構設計,而且設計工作往往都是相似設計或系列化設計,會經(jīng)常運用到已有的設計結果,其設計過程也基本一致。因此將以往的設計知識進行重用,通過迭代、修改、重組設計過程,即能夠產(chǎn)生高質量的夾具設計,實現(xiàn)夾具設計的快速化。針對現(xiàn)有夾具設計系統(tǒng)的不足,結合通用機床夾具的設計特點,在模塊化設計、參數(shù)化設計、相似原理技術的指導下,建立了機床專用夾具庫系統(tǒng)。系統(tǒng)以CATIA軟件為開發(fā)平臺,完成夾具圖形庫的零件設計、裝配設計、工程制圖等[1];以VB語言為開發(fā)環(huán)境,運用CATIA Automation技術和Macro Recording的結合建立程序庫;以Access為數(shù)據(jù)庫支撐平臺,實現(xiàn)數(shù)據(jù)庫信息的建立、修改、導入、導出;通過建立友好的人機交互界面,實現(xiàn)用戶與系統(tǒng)的連接;從而實現(xiàn)了專用夾具設計的智能化、自動化、數(shù)字化和標準化。根據(jù)夾具設計的結構特點,文章將系統(tǒng)自頂向下地按功能劃分為典型夾具案列模塊、標準件模塊、非標準件模塊、分析計算模塊、幫助模塊五大模塊[1];詳細的探討了系統(tǒng)的關鍵技術,如圖形庫、創(chuàng)建程序庫、數(shù)據(jù)庫的建立與連接、人機交互界面等;并以V形塊的系列化設計為例,對系統(tǒng)實現(xiàn)的過程進行有力的闡述。最后,文章簡單介紹了運用機床專用夾具庫進行快速設計專用夾具的工作流程和步驟。在快速設計專用夾具中,提出了采用相似實例匹配技術的方法,通過綜合交叉運用系統(tǒng)各功能模塊,實現(xiàn)了專用夾具的快速設計。通過結合實例,驗證了該系統(tǒng)可高效快捷的實現(xiàn)專用夾具設計,提高了專用夾具設計的自動化程度,加強了夾具設計的標準化、系列化。
[Abstract]:Fixture design is a structural design that integrates knowledge, empirical decision making, calculation and drawing, and the design work is often similar or serialized, often applied to existing design results. The design process is basically the same. Therefore, the previous design knowledge is reused, the design process can be iterated, modified and reorganized, that is, the high quality fixture design can be produced. Aiming at the deficiency of the existing fixture design system and combining the characteristics of general machine tool fixture design, under the guidance of modularization design, parameterized design and similarity principle technology, A special fixture library system for machine tools is established. The system uses CATIA software as the development platform to complete the parts design, assembly design and engineering drawing of the fixture graphics library [1], taking VB language as the development environment, using the combination of CATIA Automation technology and Macro Recording to establish the program library. Access is used as the database support platform to realize the establishment, modification, import and export of database information, to realize the connection between user and system by establishing friendly man-machine interface, and to realize the intelligent and automatic design of special fixture. Digitization and standardization. According to the structural characteristics of fixture design, this paper divides the system into typical fixture plan module, standard part module, non-standard part module, analysis and calculation module according to the function. Five modules of help module [1]; discusses the key technologies of the system in detail, such as graphic library, program library, database establishment and connection, man-machine interface, etc., and takes the series design of V-shaped block as an example. Finally, the paper briefly introduces the workflow and steps of rapid design of special fixture by using special fixture library of machine tool. In this paper, the method of similar case matching technology is put forward, and the rapid design of special fixture is realized by synthesizing the function modules of the system, and it is proved that the system can realize the design of special fixture efficiently and quickly by combining with an example. The automation degree of special fixture design is improved, and the standardization and serialization of fixture design are strengthened.
