Body parts of the main plane of the surface and pore system. In general, the plane guarantee processing precision than that of holes machining precision easy. Therefore, this design follows the surface after the first hole principle. Plane with holes and the processing clearly divided into roughing and finishing stages of holes to ensure machining accuracy. Datum selection box input shaft and the output shaft of the supporting hole as a rough benchmark, with top with two holes as a precision technology reference. Main processes arrangements to support holes for positioning and processing the top plane, and then the top plane and the supporting hole location hole processing technology. In addition to the follow-up processes individual processes are made of the top plane and technological hole location hole and plane processing. Supported hole processing using the method of coordinate boring. The whole process of processing machine combinations were selected. Selection of special fixture fixture, clamping means more choice of pneumatic clamping, clamping reliable, institutions can not be locked, so the production efficiency is high, suitable for large batch, line processing, can meet the design requirements.</p><p>Key words: Angle gear seat parts; fixture;</p><p>目 &nbsp;录</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>第一章 加工工艺规程设计<span class="Apple-tab-span" style="white-space:pre"></span>1</p><p>1.1 零件的分析<span class="Apple-tab-span" style="white-space:pre"></span>1</p><p>1.2 缸体加工的主要问题和工艺过程设计所应采取的相应措施<span class="Apple-tab-span" style="white-space:pre"></span>2</p><p>1.3 缸体加工定位基准的选择<span class="Apple-tab-span" style="white-space:pre"></span>3</p><p>1.4 缸体加工主要工序安排<span class="Apple-tab-span" style="white-space:pre"></span>3</p><p>1.5 机械加工余量、工序尺寸及毛坯尺寸的确定<span class="Apple-tab-span" style="white-space:pre"></span>6</p><p>1.6确定切削用量及基本工时（机动时间）<span class="Apple-tab-span" style="white-space:pre"></span>7</p><p>1.7 时间定额计算及生产安排<span class="Apple-tab-span" style="white-space:pre"></span>15</p><p>第二章 铣凸台面夹具设计<span class="Apple-tab-span" style="white-space:pre"></span>20</p><p>2.1 研究原始质料<span class="Apple-tab-span" style="white-space:pre"></span>20</p><p>2.2 定位、夹紧方案的选择<span class="Apple-tab-span" style="white-space:pre"></span>20</p><p>2.3切削力及夹紧力的计算<span class="Apple-tab-span" style="white-space:pre"></span>20</p><p>2.4 误差分析与计算<span class="Apple-tab-span" style="white-space:pre"></span>21</p><p>2.5 定向键与对刀装置设计<span class="Apple-tab-span" style="white-space:pre"></span>22</p><p>2.6 夹具体的设计<span class="Apple-tab-span" style="white-space:pre"></span>24</p><p>2.7 夹具设计及操作的简要说明<span class="Apple-tab-span" style="white-space:pre"></span>24</p><p>总 结<span class="Apple-tab-span" style="white-space:pre"></span>25</p><p>参考文献<span class="Apple-tab-span" style="white-space:pre"></span>26</p><p>致 谢<span class="Apple-tab-span" style="white-space:pre"></span>27</p><p>【详情如下】【需要咨询购买全套设计请加QQ1459919609】</p><p>可以使用的参考资料【不要的话可以删掉】.zip</p><p>工序卡2张.doc</p><p>文件清单.txt</p><p>缸体毛坯图.dwg</p><p>缸体的加工工艺及铣凸台面夹具设计【铣上小端面夹具】说明书正文.doc</p><p>缸体零件图.dwg</p><p>缸体零件图及毛坯图.dwg</p><p>过程卡片.doc</p><p>铣凸台面【铣上小端面】夹具体.dwg</p><p>铣凸台面【铣上小端面】夹具装配图.dwg</p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-7/6/6363496630549901947168447_1.gif" style="float:none;" title="缸体零件图.gif"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-7/6/6363496630573301989396159_1.gif" style="float:none;" title="缸体毛坯图.gif"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-7/6/6363496630596702022623870_1.gif" style="float:none;" title="铣凸台面【铣上小端面】夹具体.gif"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-7/6/6363496630629462085823398_1.gif" style="float:none;" title="铣凸台面【铣上小端面】夹具装配图.gif"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-7/6/6363496630707462211249104_1.jpg" style="float:none;" title="设计目录.jpg"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-7/6/6363496630774542331473748_1.jpg" style="float:none;" title="设计所包含文件.jpg"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-7/6/6363496630875942518127165_1.jpg" style="float:none;" title="设计字数统计.jpg"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-7/6/6363496632679305682890210_1.jpg" style="float:none;" title="中英文摘要.jpg"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-7/6/6363496634843029489338918_1.jpg" style="float:none;" title="过程卡片.jpg"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-7/6/6363496634911669608494636_1.jpg" style="float:none;" title="零件分析.jpg"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-7/6/6363496635086389905587851_1.jpg" style="float:none;" title="铣凸台面夹具设计部分.jpg"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-7/6/6363496635155030029041741_1.jpg" style="float:none;" title="赠送的参考工序过程卡片.jpg"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-7/6/6363496635325070325850875_1.jpg" style="float:none;" title="加工部分工序卡片.jpg"/></p><p><img src="http:/www.zhuangpeitu.com/ueditor_s/net/upload/2017-7/6/6363496635488870613444857_1.jpg" style="float:none;" title="加工部分工序卡片2.jpg"/></p><p><br/></p>
