機械制造及自動化畢業(yè)設計-減速機殼加工工藝及夾具設計

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，加工該工序的機車及機床的進給量，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。
關鍵詞：
工序，工位，工步，加工余量，定位方案，夾緊力
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.
 Keyword:
The process, worker one, worker's step , the surplus of processing, orient the scheme , clamp strength
