【正文】 2 畢業(yè)設(shè)計(jì)(論文) 題 目 汽車無極變速器從動(dòng)輪活動(dòng)盤 數(shù) 控加工工藝設(shè)計(jì) 院 (系) 機(jī)械與動(dòng)力工程學(xué)院 專業(yè)班級(jí) 學(xué)生姓名 學(xué)號(hào) 指導(dǎo)教師 職稱 講 師 評(píng)閱教師 職稱 2020 年 6 月 5 日 重慶科技學(xué)院本科生畢業(yè)設(shè)計(jì) 摘要 3 3 摘要 工藝學(xué)是研究機(jī)械加工工藝技術(shù)和夾具設(shè)計(jì)為主的技術(shù)學(xué)科 。 本次畢業(yè)設(shè)計(jì)研究 的課題是 汽車無級(jí)變速器從動(dòng)輪活動(dòng)盤數(shù)控加工工藝設(shè)計(jì) ,主要內(nèi)容如下: 首先,對(duì)零件進(jìn)行分析,主要 分析的是 零件作用、結(jié)構(gòu)和工藝的分析,通過零件分析可以了解零件的基本情況,而工藝分析可以知道零件的加工表面和加工要求。根據(jù)零件圖提出具體加工要求,確定毛坯的制造形式和尺寸 其次 ,進(jìn)行基面的選擇,確定加工過程中的精基準(zhǔn)和粗基準(zhǔn)。根據(jù)選好的基準(zhǔn),制定工藝路線方案 。接著 ,根據(jù)已經(jīng)確定的工藝路線,選擇加工設(shè)備及工藝裝備,再確定每一工步的切削用量。第四步,設(shè)計(jì) 直徑為 Φ 121mm 外圓的 夾具。先提出夾具設(shè)計(jì)任務(wù),選擇定位基準(zhǔn), 再確定夾具結(jié)構(gòu)方案,然后開始切削力、夾緊力的計(jì)算和定位誤差的分析。最后,把整個(gè)設(shè)計(jì)過程整理為設(shè)計(jì)說明書和圖紙,至此整個(gè)設(shè)計(jì)基本完成。 關(guān)鍵詞 : 從動(dòng)輪活動(dòng)盤 加工工藝 夾具設(shè)計(jì) Ⅰ 重慶科技學(xué)院本科生畢業(yè)設(shè)計(jì) 2 ABSTRACT Technology is the study of mechanical processing technology and fixture design technology subject。 The graduation design research topic is stepless transmission driven pulley plate of nc machining process design activity, The main contents are as follows: First of all, analyze the ponents, the main analysis is the parts function, structure and process analysis, we Can understand the basic information of the parts, through the analysis of the parts, And process analysis can know parts processing surface and the processing requirements, Determination of blank shape and size manufacturing。 Secondly, for the selection, determine the processing precision in the process of benchmarking and crude benchmark. 。 According to choose good benchmark, making craft route plan。 Then, according to the established process routes, choice and processing equipment and process equipment, and determine every step of cutting parameter., The fourth step, the cylindrical fixture design Φ diameter 121 mm. Fixture design is put forward first, choose the locating datum, then fixture structure scheme is determined, and then start cutting force, clamping force, calculation and analysis of fixing error。 Finally, the whole design process to design specifications and drawings, so the design pleted。 Keywords: Disc from the wheel; processing technic; fixture design Ⅱ 重慶科技學(xué)院本科生畢業(yè)設(shè)計(jì) 3 目錄 1 緒論 .............................................................................................................................. 4 零件的作用 ......................................................................................................... 4 零件的工藝分析 .................................................................................................. 4 確定毛坯的制造形成 ........................................................................................... 4 基面的選擇 ......................................................................................................... 4 制造工藝路線 ..................................................................................................... 5 機(jī)械加工余量 ..................................................................................................... 5 工藝路線方案 ..................................................................................................... 5 原始條件 ...........................................................................................................10 設(shè)計(jì)步驟 ...........................................................................................................10 選擇刀片型號(hào)和尺寸 .......................................................................................... 11 選擇硬質(zhì)合金刀墊型號(hào)和尺寸 ............................................................................ 11 計(jì)算刀槽角度 ....................................................................................................12 選擇刀桿材料和尺寸 ..........................................................................................14 選擇偏心角及其相關(guān)尺寸 ........................................................................14 3. 量具設(shè)計(jì) ...................................................................................................................15 光滑極限量規(guī)的種類 ..........................................................................................15 工作量規(guī) ...........................................................................................................15 量規(guī)公差帶的布置 .............................................................................................16 量規(guī)的技術(shù)要求 .................................................................................................17 量規(guī)的結(jié)構(gòu)型式 ............................................................................
