【正文】 ） ，是指清掃工作現(xiàn)場的灰塵、油污和垃圾，使機器設(shè)備以及工裝夾具保持清潔，保證生產(chǎn)或工作現(xiàn)場干凈整潔、無灰塵、無垃圾。對無法取消又必要者，看能否合并，以達到省時簡化的目的。上述三個要素中（指加工表面、切削刀具和切削用量）只要有一個要素改變了，就不能認為是同一個工步。因此我們項目小組的成員打算對現(xiàn)有的這臺機器進行改進設(shè)計，從而提高機器裝車胎的成功率，使這臺機器能應(yīng)用是實際生產(chǎn)中，使得機器裝配代替人手裝配這個目標(biāo)能實現(xiàn)。s tire assembly process, the use of industrial engineering, machine manufacturing techniques, such as experimental design and analysis, 5W1H questions techniques, ECRS four principles and other methods. Design the machine. Then e out with the improve program. Improvement program under test, and pare with the original manual assembly of the tire measured standard time to sum up the current pros and cons. Looking to further improve the tire assembly process method. According to the equipment in the factory, my team put forward four improvements. Each improvement in the pass rates reached 90%, and meet the pany requirements, I also proposed a fully automated assembly of tire development.Key words： Tires，Assembly, Semiautomatic3 / 38目錄1 緒論 ........................................................................................................................................................5 項目背景及目的 .............................................................................................................................5 當(dāng)前國內(nèi)、公司的研究狀況 .........................................................................................................5 現(xiàn)有設(shè)備如圖 ： ................................................................................................................6 現(xiàn)有加工對象： ....................................................................................................................7 題目研究方法 ...............................................................................................................................10 工藝過程分析法 .................................................................................................................10 “5W1H”提問技術(shù) .............................................................................................................11 “ECRS” 四大原則 ...........................................................................................................12 “5S”管理 .........................................................................................................................122 找出機器裝配存在的問題 ..................................................................................................................13 現(xiàn)有設(shè)備的裝胎的工藝運功過程...............................................................................................13 現(xiàn)有機器裝配出現(xiàn)的問題 ...........................................................................................................143 找出造成以上問題的原因 .................................................................................................................154 分析原因 .............................................................................................................................................15 造成定位不準(zhǔn)的原因 ...................................................................................................................15 輪芯入胎深度要適當(dāng) ...................................................................................................................16 車胎硬度的影響 ...........................................................................................................................16 裝胎時，輪芯側(cè)面將車胎趾口壓死，車胎趾口彈不起來 .......................................................165 初步改進：對機器的夾具進行改進，確保定位準(zhǔn)確 .....................................................................17 對現(xiàn)有設(shè)備，夾具進行改進，確保定位準(zhǔn)確 ...........................................................................17 改進后的機械原理圖如圖 、 所示: ..................................................................................18 改進的下模如圖 、 所示： .............................................................................19 設(shè)置合理的入胎深度 ...................................................................................................................216 進一步改進：改進輪芯結(jié)構(gòu)，并進行不同硬度的車胎試驗 .........................................................21 方案一：不改變輪芯結(jié)構(gòu)，嘗試不同硬度的入胎效果 .........................................................22 輪芯實例，如圖 示： ..
