【摘要】：夾具設(shè)計(jì)是集知識(shí)、經(jīng)驗(yàn)決策、計(jì)算、繪圖于一體的結(jié)構(gòu)設(shè)計(jì),而且設(shè)計(jì)工作往往都是相似設(shè)計(jì)或系列化設(shè)計(jì),會(huì)經(jīng)常運(yùn)用到已有的設(shè)計(jì)結(jié)果,其設(shè)計(jì)過程也基本一致。因此將以往的設(shè)計(jì)知識(shí)進(jìn)行重用,通過迭代、修改、重組設(shè)計(jì)過程,即能夠產(chǎn)生高質(zhì)量的夾具設(shè)計(jì),實(shí)現(xiàn)夾具設(shè)計(jì)的快速化。針對(duì)現(xiàn)有夾具設(shè)計(jì)系統(tǒng)的不足,結(jié)合通用機(jī)床夾具的設(shè)計(jì)特點(diǎn),在模塊化設(shè)計(jì)、參數(shù)化設(shè)計(jì)、相似原理技術(shù)的指導(dǎo)下,建立了機(jī)床專用夾具庫(kù)系統(tǒng)。系統(tǒng)以CATIA軟件為開發(fā)平臺(tái),完成夾具圖形庫(kù)的零件設(shè)計(jì)、裝配設(shè)計(jì)、工程制圖等[1];以VB語(yǔ)言為開發(fā)環(huán)境,運(yùn)用CATIA Automation技術(shù)和Macro Recording的結(jié)合建立程序庫(kù);以Access為數(shù)據(jù)庫(kù)支撐平臺(tái),實(shí)現(xiàn)數(shù)據(jù)庫(kù)信息的建立、修改、導(dǎo)入、導(dǎo)出;通過建立友好的人機(jī)交互界面,實(shí)現(xiàn)用戶與系統(tǒng)的連接;從而實(shí)現(xiàn)了專用夾具設(shè)計(jì)的智能化、自動(dòng)化、數(shù)字化和標(biāo)準(zhǔn)化。根據(jù)夾具設(shè)計(jì)的結(jié)構(gòu)特點(diǎn),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(biāo)準(zhǔn)件模塊、非標(biāo)準(zhǔn)件模塊、分析計(jì)算模塊、幫助模塊五大模塊[1];詳細(xì)的探討了系統(tǒng)的關(guān)鍵技術(shù),如圖形庫(kù)、創(chuàng)建程序庫(kù)、數(shù)據(jù)庫(kù)的建立與連接、人機(jī)交互界面等;并以V形塊的系列化設(shè)計(jì)為例,對(duì)系統(tǒng)實(shí)現(xiàn)的過程進(jìn)行有力的闡述。最后,文章簡(jiǎn)單介紹了運(yùn)用機(jī)床專用夾具庫(kù)進(jìn)行快速設(shè)計(jì)專用夾具的工作流程和步驟。在快速設(shè)計(jì)專用夾具中,提出了采用相似實(shí)例匹配技術(shù)的方法,通過綜合交叉運(yùn)用系統(tǒng)各功能模塊,實(shí)現(xiàn)了專用夾具的快速設(shè)計(jì)。通過結(jié)合實(shí)例,驗(yàn)證了該系統(tǒng)可高效快捷的實(shí)現(xiàn)專用夾具設(shè)計(jì),提高了專用夾具設(shè)計(jì)的自動(dòng)化程度,加強(qiáng)了夾具設(shè)計(jì)的標(biāo)準(zhǔn)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.
