The main processing direction of gear box includes milling surface, drilling hole and tapping thread. The roughness of the left and right end faces of the transmission case and the upper and lower surfaces require a high degree of roughness. The roughness of the surface is easier to meet the requirement of the machining accuracy of the hole. The distribution of holes has a regular pattern, distributed in two axes. The main guarantee is the verticality of the hole and the runout of the circle and the roughness of the inner hole surface. The design process of the actual practice, production and processing oriented, combining theoretical knowledge, Follow the design principle of the front face and the rear hole. The surface roughing and finishing are clearly separated from the roughing and finishing of the hole. Ensure dimensional accuracy and various requirements of the hole. Both the rough and the fine reference are chosen for the lower underside of the gearbox. In the processing process, the lower surface of the gear box is arranged as the positioning reference, and the upper surface is processed. The bearing hole is machined on the following end surface and the side surface of the box body. The clamping method uses the manual tightening screw thread clamp. The fixture has been specially designed. Reliable clamping is guaranteed.</p><p>This design is suitable for mass production requirements to ensure processing quality conditions, reduce production time as much as possible, improve production efficiency, reduce production as the main direction of development, but also present in machine processing industry. Because this design is for the actual production, the gearbox parts drawings are analyzed, and the transmission function and structure in many respects, that can guarantee the process to meet the production needs, and can guarantee the required size and technical requirements, and the design of the fixture box, bearing decent hole machining precision and error analysis. Ensure that the fixture can be used in practical production.</p><p>Key words: gearbox processing technology &nbsp;positioning &nbsp;clamping fixture design</p><p>目 &nbsp;錄 &nbsp;</p><p>摘 &nbsp;要<span class="Apple-tab-span" style="white-space:pre"></span>I</p><p>Abstract<span class="Apple-tab-span" style="white-space:pre"></span>II</p><p>第1章 緒論<span class="Apple-tab-span" style="white-space:pre"></span>1</p><p>1.1 選題背景<span class="Apple-tab-span" style="white-space:pre"></span>1</p><p>1.2 選題意義和發(fā)展現(xiàn)狀<span class="Apple-tab-span" style="white-space:pre"></span>1</p><p>1.3 設(shè)計的主要內(nèi)容<span class="Apple-tab-span" style="white-space:pre"></span>2</p><p>第2章 變速箱體工藝規(guī)程設(shè)計<span class="Apple-tab-span" style="white-space:pre"></span>3</p><p>2.1 零件分析<span class="Apple-tab-span" style="white-space:pre"></span>3</p><p>2.1.1 零件的作用<span class="Apple-tab-span" style="white-space:pre"></span>3</p><p>2.1.2 變速箱體結(jié)構(gòu)特點<span class="Apple-tab-span" style="white-space:pre"></span>3</p><p>2.2 變速箱體工藝性<span class="Apple-tab-span" style="white-space:pre"></span>4</p><p>2.2.1 零件工藝分析<span class="Apple-tab-span" style="white-space:pre"></span>4</p><p>2.2.2 箱體選材和毛坯控制<span class="Apple-tab-span" style="white-space:pre"></span>4</p><p>2.3 工藝路線<span class="Apple-tab-span" style="white-space:pre"></span>5</p><p>第3章 鏜孔夾具設(shè)計<span class="Apple-tab-span" style="white-space:pre"></span>8</p><p>3.1 夾具定位、夾緊確定<span class="Apple-tab-span" style="white-space:pre"></span>8</p><p>3.2 夾緊元件、動力裝置、夾緊力確定<span class="Apple-tab-span" style="white-space:pre"></span>9</p><p>3.3 夾具體、鏜套、鏜桿設(shè)計<span class="Apple-tab-span" style="white-space:pre"></span>10</p><p>3.4 夾具設(shè)計及操作簡要說明<span class="Apple-tab-span" style="white-space:pre"></span>12</p><p>第5章 刀具<span class="Apple-tab-span" style="white-space:pre"></span>13</p><p>5.1 刀具選用<span class="Apple-tab-span" style="white-space:pre"></span>13</p><p>5.2 刀具材料<span class="Apple-tab-span" style="white-space:pre"></span>13</p><p>5.3 切削控制<span class="Apple-tab-span" style="white-space:pre"></span>14</p><p>總 結(jié)<span class="Apple-tab-span" style="white-space:pre"></span>15</p><p>致 謝<span class="Apple-tab-span" style="white-space:pre"></span>16</p><p>參考文獻<span class="Apple-tab-span" style="white-space:pre"></span>17</p><p>【詳情如下】【需要咨詢購買全套設(shè)計請加QQ1459919609】</p><p>A0-變速器箱體零件圖.dwg</p><p>A0-鏜孔夾具裝配圖.dwg</p><p>A1-變速器箱體毛坯圖.dwg</p><p>A2-鏜套.dwg</p><p>變速箱箱體機械加工工藝及夾具設(shè)計開題報告.doc</p><p>外文翻譯.doc</p><p>工序卡.doc</p><p>文件清單.txt</p><p>汽車變速器箱體機械加工工藝及夾具設(shè)計文獻綜述.doc</p><p>汽車變速箱箱體機械加工工藝及鏜80孔夾具設(shè)計.docx</p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618900329217457819266_1.gif" style="float:none;" title="A0-變速器箱體零件圖.gif"/></p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618900354177507064137_1.gif" style="float:none;" title="A0-鏜孔夾具裝配圖.gif"/></p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618900388497569635364_1.gif" style="float:none;" title="A1-變速器箱體毛坯圖.gif"/></p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618900410337601636898_1.gif" style="float:none;" title="A2-鏜套.gif"/></p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618901531979575935982_1.jpg" style="float:none;" title="工序卡1.jpg"/></p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618901628699738566645_1.jpg" style="float:none;" title="工序卡2.jpg"/></p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618901730099911913228_1.jpg" style="float:none;" title="工序卡3.jpg"/></p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618901831500094259810_1.jpg" style="float:none;" title="工序卡4.jpg"/></p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618901926660265821546_1.jpg" style="float:none;" title="工序卡5.jpg"/></p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618902029620444938884_1.jpg" style="float:none;" title="工序卡6.jpg"/></p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618902132580628758049_1.jpg" style="float:none;" title="工序卡7.jpg"/></p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618903205862517039974_1.jpg" style="float:none;" title="過程卡片.jpg"/></p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618903316622708414741_1.jpg" style="float:none;" title="設(shè)計目錄.jpg"/></p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618903427382899789508_1.jpg" style="float:none;" title="設(shè)計所包含文件.jpg"/></p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618903510063045079722_1.jpg" style="float:none;" title="設(shè)計字數(shù)統(tǒng)計.jpg"/></p><p><img src="http:/italysoccerbets.com/ueditor_s/net/upload/2017-7/20/6363618903686343354757262_1.jpg" style="float:none;" title="中英文摘要.jpg"/></p><p><br/></p>
