摘要

这次设计的是曲柄锥销孔的加工，包括零件图、毛坯图、装配图各一张，机械加工工艺过程卡片一张与工序卡片一张。首先我们要熟悉零件和了解其作用，然后，根据零件的性质和零件图上各端面的粗糙度确定毛坯的尺寸和机械加工余量。最后拟定曲柄的工艺路线图，制定该工件的夹紧方案，画出夹具装配图。
机械制造课程设计,是在学完机械制造工艺学及夹具设计原理课程，经过生产实习取得感性知识后进行的一项教学环节；在老师的指导下，要求在设计中能初步学会综合运用以前所学过的全部课程，并且独立完成的一项工程基本训练。同时，也为以后搞好毕业设计打下良好基础。

关键词：锥销孔  工艺过程   机械加工余量

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.

Keyword:The awl sell the bore craft process machine to process remaining quantity
