检验两零件间装配尺寸的正确

<p>检验两零件间装配尺寸的正确<br/>将三个零件“装配”在一起，检验它们装配尺寸的正确性。这个练习的目的是使读者掌握检验零件间配合尺寸是否一致的方法。<br/>1.&nbsp; &nbsp; &nbsp; &nbsp; 打开文件<br/>2.&nbsp; &nbsp; &nbsp; &nbsp; 创建新图形文件，文件名为“装配检验.dwg”。<br/>3.&nbsp; &nbsp; &nbsp; &nbsp; 切换到图形“10-3-A.dwg”，关闭标注层。在图形窗口中单击右键，弹出光标菜单，选择“带基点复制”选项，AutoCAD提示：<br/>指定基点:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //指定适当的复制基点<br/>选择对象: &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //选择零件的主视图，如图10-6所示。<br/><img id="img_0.18165123774919828" height="235" alt="" src="http://www.ttketang.com/home/attachment/200909/2/113_1251857586X6GC.jpg" width="323"/><br/>10-6复制主视图<br/>4.&nbsp; &nbsp; &nbsp; &nbsp; 切换到图形“装配检验.dwg”，在图形窗口中单击右键，弹出光标菜单，选择“粘贴”选项，结果如图10-7所示。<br/><img id="img_0.4676719556970261" height="234" alt="" src="http://www.ttketang.com/home/attachment/200909/2/113_12518575884AOQ.jpg" width="325"/>
                <br/>10-7粘贴图形<br/>5.&nbsp; &nbsp; &nbsp; &nbsp; 切换到图形“10-3-B.dwg”，关闭标注层。在图形窗口中单击右键，弹出光标菜单，选择“带基点复制”选项，AutoCAD提示：<br/>指定基点:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //指定适当的复制基点<br/>选择对象: &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //选择零件的主视图，如图10-8所示。<br/><img id="img_0.9449118693670423" height="227" alt="" src="http://www.ttketang.com/home/attachment/200909/2/113_1251857590Zori.jpg" width="310"/>
                <br/>10-8复制主视图<br/>6.&nbsp; &nbsp; &nbsp; &nbsp; 切换到图形“装配检验.dwg”，在图形窗口中单击右键，弹出光标菜单，选择“粘贴”选项，结果如图10-9所示。<br/><img id="img_0.16417882508684756" height="222" alt="" src="http://www.ttketang.com/home/attachment/200909/2/113_1251857596obZX.jpg" width="305"/>
                <br/>10-9粘贴图形<br/>7.&nbsp; &nbsp; &nbsp; &nbsp; 用MOVE命令将两个零件装配在一起，结果如图10-10所示。由图可以看出，两零件正确地配合在一起，它们的装配尺寸是正确的。<br/><img id="img_0.873413800779342" height="235" alt="" src="http://www.ttketang.com/home/attachment/200909/2/113_125185760166sC.jpg" width="326"/>10-10“装配”两个零件<br/>提示：也可采用外部参照的方法将其他零件图插入当前图样中，然后将它们装配在一起以检查配合尺寸的正确性。<br/>8.&nbsp; &nbsp; &nbsp; &nbsp; 用上述同样的方法将零件“10-3-B”与“10-3-A”也装配在一起，结果如图10-11所示。由图可以看出，零件“10-3-B”与“10-3-A”正确地配合在一起，它们的装配尺寸是正确的。<br/><img id="img_0.4339173643827673" height="235" alt="" src="http://www.ttketang.com/home/attachment/200909/2/113_1251857602B3gm.jpg" width="322"/>
