摘要
這次設計的是曲柄錐銷孔的加工，包括零件圖、毛坯圖、裝配圖各一張，機械加工工藝過程卡片一張與工序卡片一張。首先我們要熟悉零件和了解其作用，然后，根據(jù)零件的性質和零件圖上各端面的粗糙度確定毛坯的尺寸和機械加工余量。最后擬定曲柄的工藝路線圖，制定該工件的夾緊方案，畫出夾具裝配圖。
機械制造課程設計,是在學完機械制造工藝學及夾具設計原理課程，經(jīng)過生產實習取得感性知識后進行的一項教學環(huán)節(jié)；在老師的指導下，要求在設計中能初步學會綜合運用以前所學過的全部課程，并且獨立完成的一項工程基本訓練。同時，也為以后搞好畢業(yè)設計打下良好基礎。
關鍵詞：錐銷孔 工藝過程 機械加工余量
Summary
This time design of is a crank awl to sell process of bore, include spare parts diagram, semi-finished product diagram, assemble diagram one for each, the machine process the card 1 and work preface of the craft process card 1.We want to acquaint with spare parts and understanding its function first, then, according to property and spare parts diagram of the spare parts top each carry noodles of rough degree assurance semi-finished product of size and machine process remaining quantity.End draw-up crank of craft route diagram, establishment should clip of work piece tight project, painting tongs assemble diagram.
Machine manufacturing course design, is learn to finish a machine manufacturing craft to learn and tongs design principle course, has been produced practice to obtain sensitive faculty knowledge juniors line of a teaching link;At teacher of instruction bottom, request at design in ability first step academic association comprehensive usage before once learn of all course, and independence completion of an engineering be basic train.In the meantime, is also later make good graduation design dozen descend good foundation.
