ZQ350 型減速機(jī) 機(jī)體 加工工藝及 銑機(jī) 座結(jié)合面和鉆 10ф17 孔 夾具設(shè)計(jì) 摘 要 本次畢業(yè)設(shè)計(jì)的題目是“ ZQ350 減速器機(jī)體工藝規(guī)程及工裝夾具設(shè)計(jì)”,其主要任務(wù)有兩項(xiàng):第一項(xiàng)是箱體零件加工工藝規(guī)程的設(shè)計(jì);第二項(xiàng)是箱體零件工裝夾具的設(shè)計(jì)。在工藝規(guī)程的設(shè)計(jì)中,首先對零件進(jìn)行分析,根據(jù)生產(chǎn)綱領(lǐng)、零件材料及其它要求來確定毛坯的制造形式;其次根據(jù)基準(zhǔn)選擇原則進(jìn)行粗基準(zhǔn)和精基準(zhǔn)的選擇,然后擬定工藝路線,通過綜合比較與分析確定最終工藝方案;最后進(jìn)行機(jī)械加工余量、工序尺 寸、毛坯尺寸、切削用量及基本工時的確定。在工裝夾具部分的設(shè)計(jì)中,首先是定位方案的確定,根據(jù)各道工序的加工特點(diǎn)合理的選擇定位基準(zhǔn)并進(jìn)行誤差分析,如果定位基準(zhǔn)與設(shè)計(jì)基準(zhǔn)不重合則要進(jìn)行尺寸鏈的計(jì)算;其次根據(jù)加工特點(diǎn)進(jìn)行切削力的計(jì)算,綜合以上因素設(shè)計(jì)合理的夾緊方案并計(jì)算夾緊力,最后進(jìn)行夾具整體設(shè)計(jì)。 關(guān)鍵詞 : 減速器 , 工藝規(guī)程 , 工裝夾具 。 攀枝花學(xué)院本科畢業(yè)設(shè)計(jì)(論文) ABSTRACT II ABSTRACT The title of graduation project is the design of ZQ350 reducer body of technological procedure and assembly technology clamp there are two main tasks: The first is the design of technological procedure of box parts ,and the second is the design of assembly technology clamp of box parts .During the design of technological procedure, the first step is to analysis the parts according to production program, materials of parts and the other requirements ,and to determine the manufacture form of rough。the followed is to select rough and precise in accordance with the principles of reference, then deciding the process routes ,and detetmining the final programme by the Integrated Comparison and analysis 。 the final is to determine mechanical allowance, process dimension, blank dimensions, cutting parameters and the basic working hours. In the design of part of assembly technology clamp, the first is the determination of location programme,choosing location reference reasonably and analysising error in accordance with the characteristics of every process. if the location reference does not coincide with design reference , we must work out the dimension chain。the followed is the calculation of the cutting force by the characteristics of the processing .considering all the factors ,we will design the clamping programmes reasonably and calculate the clamping force, and design the clamp finally. Key words: reducer。 technological procedure。 assembly technology clamp 攀枝花學(xué)院本科畢業(yè)設(shè)計(jì)(論文) 目錄 1 目 錄 摘 要 .........................................................................
