香烟横包机右支架工艺规程及夹具设计 学生姓名： 郑帅栋 班级： 068105337 指导老师： 罗海泉 摘要： 本课题是香烟横包机右支架的机械加工工艺设计和镗床镗模设计，因为 零件本身不是很复杂，而且加工精度不是很高，所以其工艺简单。通过对零件的工艺分析，设计了工艺规程，确定了其毛坯的制造形式、加工基准和设计基准、工艺路线、机械加工余量和各工序的切削用量及基本工时，也确定了选用的刀具与机床。为提高劳动生产效率，降低劳动强度， 设计了 三个平行孔的 专用夹具，基于 零件的几何形状，设计其夹具为 T68镗床上的专用镗模，通过对其定位基准、引刀方式、夹紧方案的选择，最终确定了主要用于加工零件的孔系的镗模，它依靠专用的导向元件 镗套引导镗孔刀具，保证了加工达到了较高的位置精度，并使镗孔的位置精度不受机床精度的影响，利用其夹具精加工孔系时保证了平行孔轴线距误差小于 0.02mm；平行孔的不平行或不垂直度小于 0.01/200；平行孔不同轴度误差小于 0.01mm。 关键词： 加工工艺， 夹具，加工精度，镗模 指导老师签名： nts The right support cigarettes horizontal packaging machines Technology of order and Fixture design Student name : zhengshuaidong Class:0681053 Supervisor: Luo Haiquan Abstract:The issue is the right of cigarettes Wang charter stent machining process design and boring - boring machine design, because parts itself is not very complicated and machining accuracy is not very high, so its simple process. Part of the process analysis, design of process in order and set its rough form the manufacture, processing benchmarks and design criteria, process line, machinery allowance and the amount of the cutting process and the basic hours of work, defines the use of knives and machine tools. To improve labor productivity and reduce labor intensity, the three parallel design Kong special fixture, Based on the geometry of components, fixture design for its T68 Boring Boring on the dedicated mode, through its positioning benchmarks primers knife, the choice of clamping program, and the final of the main components for the processing of boring holes mold, It relies on a dedicated oriented components - guide sets Boring Boring Tool ensure that the processing to achieve a higher position accuracy, Boring enable the location accuracy from the impact of precision machine tools, use their fixture finishing holes at ensuring the parallel hole axis from the error is less than 0.02 mm; The parallel hole parallel or vertical is less than 0.01/200; Hole different parallel axis error of less than
