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;录</p><p>1绪论1</p><p>&nbsp;1.1概述1</p><p>&nbsp; 1.1.1车床夹具的分类1</p><p>&nbsp; 1.1.2夹具的组成2</p><p>&nbsp; 1.1.3夹具体3</p><p>&nbsp; 1.1.4车床夹具在机械加工中的作用3</p><p>&nbsp; 1.1.5车床夹具在车床中的地位及作用3</p><p>&nbsp; 1.1.6国内外夹具的发展与趋势4</p><p>&nbsp;1.2夹具研究现状5</p><p>&nbsp; 1.2.1机床夹具的现状5</p><p>&nbsp; 1.2.2现代机床夹具的发展方向6</p><p>&nbsp;1.3国内外对组合夹具的发展及研究状况7</p><p>&nbsp; 1.3.1国内对组合夹具的发展状况7</p><p>&nbsp; 1.3.2国外对组合夹具的发展状况8</p><p>&nbsp;1.4本文主要研究内容9</p><p>2零件分析10</p><p>&nbsp;2.1零件的选择与分析10</p><p>&nbsp;2.2工艺路线的确定10</p><p>&nbsp;2.3总体设计中对夹具设计的重要的参数 11</p><p>3车床组合的夹具设计 &nbsp;12&nbsp;</p><p>&nbsp;3.1夹具设计要求与选型12</p><p>&nbsp; 3.1.1夹具设计要求12</p><p>&nbsp; 3.1.2夹具的选型13</p><p>&nbsp;3.2定位和夹紧方案的确定13</p><p>&nbsp; 3.2.1定位和夹紧方案的选择分析14</p><p>&nbsp;3.3定位元件和夹紧元件的设计计算15</p><p>&nbsp; 3.3.1定位元件的设计计算 15</p><p>&nbsp; 3.3.2夹紧机构的设计计算16</p><p>&nbsp;3.4误差分析计算17</p><p>&nbsp; 3.4.1影响加工精度的因素17</p><p>&nbsp; 3.4.2误差的计算17</p><p>&nbsp;3.4.3保证加工精度 18</p><p>&nbsp;3.5夹具结构的确定19</p><p>&nbsp; 3.5.1夹具体的确定19</p><p>&nbsp;3.6夹紧力的确定21</p><p>&nbsp; 3.6.1夹紧力的计算公式21</p><p>&nbsp; 3.6.2夹紧力的计算22</p><p>4 结论 24</p><p>参考文献25</p><p>致谢26</p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-6/2/6363204178116731963345486_1.gif" style="float:none;" title="挡铁.gif"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-6/2/6363204178143252013031688_1.gif" style="float:none;" title="定位块2张.gif"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-6/2/6363204178174452063001970_1.gif" style="float:none;" title="法兰盘.gif"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-6/2/6363204178205652122972252_1.gif" style="float:none;" title="连接板.gif"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-6/2/6363204178260252215170246_1.gif" style="float:none;" title="螺柱.gif"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-6/2/6363204178296132285424609_1.gif" style="float:none;" title="三通阀零件图.gif"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-6/2/6363204178324212333638228_1.gif" style="float:none;" title="压板.gif"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-6/2/6363204178380372439065467_1.gif" style="float:none;" title="装配图.gif"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-6/2/6363204178508292651703259_1.png" style="float:none;" title="360桌面截图20170602170803.png"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-6/2/6363204180072975405203279_1.png" style="float:none;" title="360桌面截图20170602225133.png"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-6/2/6363204180399015976161997_1.png" style="float:none;" title="360桌面截图20170602225211.png"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-6/2/6363204180472336105601795_1.png" style="float:none;" title="360桌面截图20170602225304.png"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-6/2/6363204180675136469908630_1.png" style="float:none;" title="360桌面截图20170602225332.png"/></p><p><br/></p>
