車床套工藝及夾具設計
摘 要
工藝學是以研究機械加工工藝和夾具設計為主的一門學科,具有很強的實踐性,要求在學習過程中應緊密聯(lián)系生產(chǎn)實踐,同時它又具有很強的綜合性,
本次畢業(yè)設計的課題是車床套加工工藝規(guī)程的制定及后三道工序專用夾具設計,主要內容如下:
首先,對零件進行分析,主要是零件作用的分析和工藝分析,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)零件圖提出的加工要求,確定毛坯的制造形式和尺寸的確定。
第二步,進行基面的選擇,確定加工過程中的粗基準和精基準。根據(jù)選好的基準,制訂工藝路線,通常制訂兩種以上的工藝路線,通過工藝方案的比較與分析,再選擇可以使零件的幾何形狀、尺寸精度及位置精度等技術要求得到合理的保證的一種工序。
第三步,根據(jù)已經(jīng)選定的工序路線,確定每一工步的切削用量及基本工時,并選擇合適的機床和刀具、量具。對于粗加工,還要校核機床功率。
最后,經(jīng)過多方面的考慮,設計了后三道工序的專用夾具,即兩套鉆模和一套銑臺階面的銑床夾具。先提出設計問題,再選擇定位基準,然后開始切削力、夾緊力的計算和定位誤差的分析。然后把設計的過程整理為圖紙,并編寫說明書。
通過以上的概述,整個設計基本完成。

LATHER SET'S TECHNOLOGY AND FIXTURE DESIGN
ABSTRACT
A specialized main specialized course that " mechanical manufacturing engineering is studied " is machinery , rely mainly on studying machining technology and jig to design technological discipline , have very strong practicality , require that should contact production practices closely in the learning process, at the same time it has comprehensive the very strong one,
The topic of this graduation design is the lather set establishment and empress that processes craft regulations three work preface appropriation tongs designs, the main contents is as follows:
First of all, analyze , it is mainly analysis of the function of the part and craft analysis to the part , through part analyze can find out about basic situation of part, and craft analyze may know the processing surface of the part and is it require to process. The processing demand put forward according to the part picture, confirm the manufacture form of the blank and sureness of the size.
The second step, carry on the choice the base , confirm thick datum and precise datum in the processing course. According to the datum chosen , make the craft route , usually make the craft route of more than two kinds, with analyzing through the comparison of the craft scheme, and then choosing be able to make such specification requirements as the precision of geometry form , size of the part and precision of position ,etc. get a kind of process of the rational assurance s.
The third step, according to the already selected process route, confirm for every steps of cutting consumption and basic man-hour , choose suitable lathe and cutter. To rough machining , will check the power of the lathe .
End, pass by various of consideration, after designing three appropriation tongses of work prefaces, namely two sets of miller tongses that drill the mold and a set of Xian step noodles.Put forward the question of designing first , and then choose to orient the datum , then the calculation that begins to cut strength , clamp strength and analysis of the localization error. Then put the design course in order as the drawing.
Through the summary of the above, design and finish basically entirely.
Keywords:machine, Lather set,Process the craft,The fixture design
