The long V block putted in the arch ribbed plate to limit two degrees of freedom in the x axis and the z axes two degrees of freedom, the iron putted in the hole end limit to the degree of freedom which circle the y rotation of axis, the supporting block putted under the ribbed plate to limit degree of freedom along the y axis migration. Position error is reckoned by the correlation principle. According to the way of the selection principle, discharge head and V block is selected to clamp the part. Then computation of the strength is achieved by carrying on through the cutting force clamps. The power of clamps is from the hydraulic unit. Design of bridge piece is according to the location part and the clamp part. The guide part designing in this topic is not requested because the cutter bar is short. Other parts and equipment are designed following last process.&nbsp;</p><p>&nbsp; &nbsp; The jig overall arrangement and concrete structure of the body clamp are determined with the above part and the equipment. The position of the components in the kits specific location must be guaranteed, and then design the jig, carry on the working procedure precision analysis. The design review is following. Finally the jig assembly drawing is achieved.</p><p>Keywords: Modular jig and fixture; location; clamp; union tee</p><p>目 &nbsp;錄</p><p>1緒論1</p><p>&nbsp;1.1概述1</p><p>&nbsp; 1.1.1車床夾具的分類1</p><p>&nbsp; 1.1.2夾具的組成2</p><p>&nbsp; 1.1.3夾具體3</p><p>&nbsp; 1.1.4車床夾具在機(jī)械加工中的作用3</p><p>&nbsp; 1.1.5車床夾具在車床中的地位及作用3</p><p>&nbsp; 1.1.6國內(nèi)外夾具的發(fā)展與趨勢4</p><p>&nbsp;1.2夾具研究現(xiàn)狀5</p><p>&nbsp; 1.2.1機(jī)床夾具的現(xiàn)狀5</p><p>&nbsp; 1.2.2現(xiàn)代機(jī)床夾具的發(fā)展方向6</p><p>&nbsp;1.3國內(nèi)外對組合夾具的發(fā)展及研究狀況7</p><p>&nbsp; 1.3.1國內(nèi)對組合夾具的發(fā)展?fàn)顩r7</p><p>&nbsp; 1.3.2國外對組合夾具的發(fā)展?fàn)顩r8</p><p>&nbsp;1.4本文主要研究內(nèi)容9</p><p>2零件分析10</p><p>&nbsp;2.1零件的選擇與分析10</p><p>&nbsp;2.2工藝路線的確定10</p><p>&nbsp;2.3總體設(shè)計中對夾具設(shè)計的重要的參數(shù) 11</p><p>3車床組合的夾具設(shè)計 &nbsp;12&nbsp;</p><p>&nbsp;3.1夾具設(shè)計要求與選型12</p><p>&nbsp; 3.1.1夾具設(shè)計要求12</p><p>&nbsp; 3.1.2夾具的選型13</p><p>&nbsp;3.2定位和夾緊方案的確定13</p><p>&nbsp; 3.2.1定位和夾緊方案的選擇分析14</p><p>&nbsp;3.3定位元件和夾緊元件的設(shè)計計算15</p><p>&nbsp; 3.3.1定位元件的設(shè)計計算 15</p><p>&nbsp; 3.3.2夾緊機(jī)構(gòu)的設(shè)計計算16</p><p>&nbsp;3.4誤差分析計算17</p><p>&nbsp; 3.4.1影響加工精度的因素17</p><p>&nbsp; 3.4.2誤差的計算17</p><p>&nbsp;3.4.3保證加工精度 18</p><p>&nbsp;3.5夾具結(jié)構(gòu)的確定19</p><p>&nbsp; 3.5.1夾具體的確定19</p><p>&nbsp;3.6夾緊力的確定21</p><p>&nbsp; 3.6.1夾緊力的計算公式21</p><p>&nbsp; 3.6.2夾緊力的計算22</p><p>4 結(jié)論 24</p><p>參考文獻(xiàn)25</p><p>致謝26</p><p><img src="http:/ioszen.com/ueditor_s/net/upload/2017-6/2/6363204178116731963345486_1.gif" style="float:none;" title="擋鐵.gif"/></p><p><img src="http:/ioszen.com/ueditor_s/net/upload/2017-6/2/6363204178143252013031688_1.gif" style="float:none;" title="定位塊2張.gif"/></p><p><img src="http:/ioszen.com/ueditor_s/net/upload/2017-6/2/6363204178174452063001970_1.gif" style="float:none;" title="法蘭盤.gif"/></p><p><img src="http:/ioszen.com/ueditor_s/net/upload/2017-6/2/6363204178205652122972252_1.gif" style="float:none;" title="連接板.gif"/></p><p><img src="http:/ioszen.com/ueditor_s/net/upload/2017-6/2/6363204178260252215170246_1.gif" style="float:none;" title="螺柱.gif"/></p><p><img src="http:/ioszen.com/ueditor_s/net/upload/2017-6/2/6363204178296132285424609_1.gif" style="float:none;" title="三通閥零件圖.gif"/></p><p><img src="http:/ioszen.com/ueditor_s/net/upload/2017-6/2/6363204178324212333638228_1.gif" style="float:none;" title="壓板.gif"/></p><p><img src="http:/ioszen.com/ueditor_s/net/upload/2017-6/2/6363204178380372439065467_1.gif" style="float:none;" title="裝配圖.gif"/></p><p><img src="http:/ioszen.com/ueditor_s/net/upload/2017-6/2/6363204178508292651703259_1.png" style="float:none;" title="360桌面截圖20170602170803.png"/></p><p><img src="http:/ioszen.com/ueditor_s/net/upload/2017-6/2/6363204180072975405203279_1.png" style="float:none;" title="360桌面截圖20170602225133.png"/></p><p><img src="http:/ioszen.com/ueditor_s/net/upload/2017-6/2/6363204180399015976161997_1.png" style="float:none;" title="360桌面截圖20170602225211.png"/></p><p><img src="http:/ioszen.com/ueditor_s/net/upload/2017-6/2/6363204180472336105601795_1.png" style="float:none;" title="360桌面截圖20170602225304.png"/></p><p><img src="http:/ioszen.com/ueditor_s/net/upload/2017-6/2/6363204180675136469908630_1.png" style="float:none;" title="360桌面截圖20170602225332.png"/></p><p><br/></p>
