香煙橫包機右支架工藝規(guī)程及夾具設(shè)計
學(xué)生姓名：鄭帥棟 班級：068105337
指導(dǎo)老師：羅海泉
摘要：本課題是香煙橫包機右支架的機械加工工藝設(shè)計和鏜床鏜模設(shè)計，因為零件本身不是很復(fù)雜，而且加工精度不是很高，所以其工藝簡單。通過對零件的工藝分析，設(shè)計了工藝規(guī)程，確定了其毛坯的制造形式、加工基準(zhǔn)和設(shè)計基準(zhǔn)、工藝路線、機械加工余量和各工序的切削用量及基本工時，也確定了選用的刀具與機床。為提高勞動生產(chǎn)效率，降低勞動強度，設(shè)計了三個平行孔的專用夾具，基于零件的幾何形狀，設(shè)計其夾具為T68鏜床上的專用鏜模，通過對其定位基準(zhǔn)、引刀方式、夾緊方案的選擇，最終確定了主要用于加工零件的孔系的鏜模，它依靠專用的導(dǎo)向元件——鏜套引導(dǎo)鏜孔刀具，保證了加工達(dá)到了較高的位置精度，并使鏜孔的位置精度不受機床精度的影響，利用其夾具精加工孔系時保證了平行孔軸線距誤差小于±0.02mm；平行孔的不平行或不垂直度小于0.01/200；平行孔不同軸度誤差小于0.01mm。

The right support cigarettes horizontal packaging machine’s 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 0.01 mm.
