摘要
這次設(shè)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(jī)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(zhì)和零件圖上各端面的粗糙度確定毛坯的尺寸和機(jī)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(jī)械制造課程設(shè)計,是在學(xué)完機(jī)械制造工藝學(xué)及夾具設(shè)計原理課程,經(jīng)過生產(chǎn)實(shí)習(xí)取得感性知識后進(jìn)行的一項(xiàng)教學(xué)環(huán)節(jié);在老師的指導(dǎo)下,要求在設(shè)計中能初步學(xué)會綜合運(yùn)用以前所學(xué)過的全部課程,并且獨(dú)立完成的一項(xiàng)工程基本訓(xùn)練。同時,也為以后搞好畢業(yè)設(shè)計打下良好基礎(chǔ)。

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.
