【正文】 0或A1） 1張6．繪制夾具中1個(gè)零件圖（A1或A2。裝配圖出來后，由指導(dǎo)教師為學(xué)生指定需繪制的零件圖，一般為夾具體）。（約50008000字） 1份四、進(jìn)度安排本課程設(shè)計(jì)要求在3周內(nèi)完成。2．第3～7天，完成零件的工藝性分析,確定毛坯的類型、制造方法，編制機(jī)械加工工藝規(guī)程和所加工工序的機(jī)械加工工序卡片。4．第11～13天，完成夾具裝配圖的繪制。6．第16～18天，整理并完成設(shè)計(jì)說明書的編寫。答辯五、指導(dǎo)教師評語該生設(shè)計(jì)的過程中表現(xiàn) ，設(shè)計(jì)內(nèi)容反映的基本概念及計(jì)算 ，設(shè)計(jì)方案 ，圖紙表達(dá) ，說明書撰寫 ，答辯表現(xiàn) 。參閱有關(guān)技術(shù)手冊，制定了機(jī)械加工工藝路線，確定了各工序尺寸和加工余量。為了給生產(chǎn)的計(jì)劃、調(diào)度、工人的操作提供依據(jù)，提高勞動生產(chǎn)率，保證加工質(zhì)量，降低勞動強(qiáng)度，根據(jù)加工需要設(shè)計(jì)了一套工裝夾具。首先我們要熟悉零件和了解其作用，它位于車床變速機(jī)構(gòu)中，主要起換檔作用。最后擬定撥差的工藝路線圖，制定該工件的夾緊方案，畫出夾具裝配圖。夾具分析AbstractThrough the analysis of the cross shaft parts, in order to meet the processing requirements, determine the form of cross shaft. Refer to the technical manual, establishes the machining processes, each process to determine the size and the machining allowance. Cutting margin and the basic working hours were determined through calculation, and establishes the machining process card. In order to provide basis for production planning, scheduling, the operation of the workers, improve labor productivity, guaranteed the processing quality, reduce labor intensity, according to processing needs a set of engineering design fixture.This design is the cross shaft machining process planning and process equipment design, including the parts drawing, blank drawing, assembly drawing of a, machining process with the card and process card. First of all we must familiar with the parts and understand its role, it is located in the lathe speed institutions, mainly from the shift effect. Then, according to the nature of parts and ponents in the face of the map on the roughness of rough determine the size and mechanical Jiagongyuliang. Finalizing the shifting fork of the road map, the enactment of the workpiece clamping programme, to draw fixture assembly.Key words：cross spider。 jig analy目 錄序 言 1零件的分析 1 1 2工藝規(guī)程設(shè)計(jì) 2 2 2 3 3 4 確定各表面的加工方法 4 4 制定工藝路線 工序尺寸及毛坯尺寸的確定 7（φ25mm） 7（108mm） 8 8（鉆孔、攻螺紋） 9 9
