包括論文，cad圖紙，答辯ppt，任務書，工序卡等完整全套畢業(yè)設計作品

內容摘要
在生產過程中，使生產對象（原材料，毛坯，零件或總成等）的質和量的狀態(tài)發(fā)生直接變化的過程叫工藝過程，如毛坯制造，機械加工，熱處理，裝配等都稱之為工藝過程。在制定工藝過程中，要確定各工序的安裝工位和該工序需要的工步，加工該工序的機床及機床的進給量，切削深度，主軸轉速和切削速度，該工序的夾具，刀具及量具，還有走刀次數(shù)和走刀長度，最后計算該工序的基本時間，輔助時間和工作地服務時間。
由于其加工批量很大，專用夾具設計中參考了許多成熟的結構，本設計結構簡單、操作方便，使用了大量的標準元件，大大縮短了本工序的輔助時間，一定程度上提高了勞動生產率，減輕了工人的勞動強度。
關鍵詞：
工序，工位，工步，加工余量，定位方案，夾緊力，專用夾具。
   
   
   

Abstract
Enable producing the target in process of production (raw materials, the blank , state of quality and quantity on part become always ) take place direct course of change ask craft course, if the blank is made, machining, heat treatment , assemble etc. and call it the craft course. In the course of making the craft , is it confirm every erector location and worker step that process need this of process to want, the locomotive of processing , this process , and the entering the giving amount of the lathe, cut depth , the rotational speed of the main shaft and speed of cutting, the jig of this process, the cutter and measuring tool, a one hundred sheets of number of times still leaves and a one hundred sheets of length leaves, calculate basic time of this process , auxiliary time and service time of place of working finally.Because the processing batch to be very big, in the design has referred to many mature structures, this design structure is simple, the ease of operation, has used the massive standard components, reduced this working procedure non-cutting time greatly, in the certain extent raised the labor productivity, reduced worker's labor intensity.
 
Keyword:
The process, worker one, worker's step , the surplus of processing, orient the scheme , clamp strength, Unit clamp .
