工質(zhì)量但是耗費(fèi)了高的成本;用普通設(shè)備加工降低了成本但是又付出了加工質(zhì)量往往不符合設(shè)計(jì)要求的兩難境地。因而需要設(shè)計(jì)一臺(tái)專機(jī)達(dá)到提高工作效率,降低生產(chǎn)成本,同時(shí)保證加工質(zhì)量的目的。 畢業(yè)設(shè)計(jì)(論文) 題目: 皮圈架座組合機(jī)床及專用夾具設(shè)計(jì) II 無錫 太湖學(xué)院本科畢業(yè)設(shè)計(jì)(論文) 誠 信 承 諾 書 本人鄭重聲明:所呈交的畢業(yè)設(shè)計(jì)(論文) 皮圈架座組合機(jī)床及專用夾具設(shè)計(jì) 是本人在導(dǎo)師的指導(dǎo)下獨(dú)立進(jìn)行研究所取得的成果,其內(nèi)容除了在畢業(yè)設(shè)計(jì)(論文)中特別加以標(biāo)注引用,表示致謝的內(nèi)容外,本畢業(yè)設(shè)計(jì)(論文)不包含任何其他個(gè)人、集體已發(fā)表或撰寫的成果作品。 班 級(jí): 機(jī)械 94 學(xué) 號(hào): 0923197 作者姓名: 20xx 年 5 月 25 日 I 無錫 太湖學(xué)院 信 機(jī) 系 機(jī)械工程及自動(dòng)化 專業(yè) 畢 業(yè) 設(shè) 計(jì)論 文 任 務(wù) 書 一、題目及專題: 題目 皮圈架座組合機(jī)床及專用夾具設(shè)計(jì) 專題 二、課題來源及選題依據(jù) 無錫市江泰機(jī)械制造廠是一家專業(yè)從事外協(xié)件加工的企業(yè),公司現(xiàn)采用加工中心加工紡織機(jī)械零件 皮圈架座上的三個(gè)孔,工裝時(shí)間長,加工成本高,效率不高。 本課題的研究意義在與使企業(yè)能根據(jù)自己的要求自主創(chuàng) 新、自發(fā)研究設(shè)計(jì)制造設(shè)備,提高自身在國內(nèi)甚至國際制造行業(yè)中的競爭力。通過本課題研究,就力求解決這種問題,使組合機(jī)床的加工保質(zhì)性和經(jīng)濟(jì)性凸顯。 它一般 采用多軸,多刀,多過程,多方位多站同時(shí)處理方法,生產(chǎn)效率高,比一般機(jī)器幾個(gè)幾倍到幾十倍。因此, 組合機(jī)床 在大規(guī)模生產(chǎn)的低成本和高效率的優(yōu)點(diǎn)相結(jié)合,已被廣泛地使用,可用于形成自動(dòng)生產(chǎn)線。主要有以下幾個(gè)方面: ( 1)制定工藝方案。確定在組合機(jī)床上完成的工藝內(nèi)容及其加工方法。 ( 2)機(jī)床結(jié)構(gòu)方案的分析和確定。在選擇機(jī)床配置型式時(shí),既要考慮實(shí)現(xiàn)工藝方案,保證加工精度、技術(shù)要求及生產(chǎn)效率;又要考慮機(jī)床操作、維護(hù)、修理是否方便,排屑情況是否良好。確定機(jī)床各個(gè)部件間的相互關(guān)系,選擇通用部件和刀具的導(dǎo)向,計(jì)算切削用量及機(jī)床生產(chǎn)率。 關(guān)鍵詞 :組合機(jī)床;多軸箱;三圖一卡;夾具設(shè)計(jì) IV Abstract With the gradual improvement of automation, machine tool more and more in modern factories, machine tool based on mon ponents, together with the specific shape of the workpiece and process design special parts and fixtures, posed of semiautomatic or automatic dedicated machine. It is monly used multiaxis, multitool, multiprocess, multifaceted or multistation processing at the same time, the production efficiency several times or more higher than the general machine. Common ponents have been standardized for serialization, can be flexibly configured, you can shorten the design and manufacturing cycle. Therefore, the bination of machine bines the advantages of low cost and high efficiency has been widely used in mass production, and can be used to form an automatic production line. The design for the apron mountings drill special machine tools, pleted three hole machining. Mainly the following aspects: (1) to develop a process plan. Learn about the processing characteristics of the machined parts, precision and technical requirements, the positioning clamping and productivity requirements. Determine the bination of machine tool technology content and its processing method. To determine the number of processing steps, determine the type of tool and type. (2)Machine analysis of the structure of the program and OK. According to the technical program to determine the type and the overall layout of the machine. Machine configuration type is selected, it is necessary to consider the process scheme to ensure accuracy, technical requirements and production efficiency。 multiaxle。 fixture design V 目 錄 摘 要 ............................................................................................................................................III Abstract. ........................................................................................................................................
