Description

气动式精密环形工件内定位面夹持装置 技术领域
本发明属于工夹器具，主要涉及装备制造领域中的精密环形工件夹持装置。
背景技术
在超精密计量测试和超精密加工领域中，高速、稳定、定位精确的夹持装置是进行精密测量和航空发动机装配的基本保证。目前，随着材料科学的进步，以及超精密测量仪器和超精密加工制造设备的精度等级的提高，高精度的环形工件的设计应用越来越广泛，其加工过程中的器具成为保证加工精度的基础。
合肥工业大学提出一种摆杆式轴向扣紧卡盘(一种摆杆式轴向扣紧卡盘。专利公开号：CN 201210212982.1)。该方案设计了动力卡盘体和夹紧卡盘体，径向均匀分布三个滑槽并嵌有底爪和推爪，上方设有摆杆组件，该结构能够克服工件结构复杂时传统卡盘难以夹持的问题。该方案的问题在于，采用轴向夹紧，不适合薄壁圆筒形工件。
北京七星华创电子股份有限公司提出一种盘状物夹持装置(盘状物夹持装置。专利公开号：CN 201110365937.5)。该方案主要包括卡盘主体、凸轮、限位块、至少三个夹持部件，凸轮随卡盘主体转动时，限位块沿卡盘主体径向固定所述夹持部件，该结构的特点是不限定机械手的夹持位置，实现了再不损坏被夹物件的情况下对盘状物的夹持。该方案的问题在于，采用外卡设计，夹持部件会对轮廓产生形变，对超精密零件来说不可忽视。
专利号US4840387提出了一种对开螺母和卡盘互相配合紧锁的装卡装置，该结构的特点是可靠性高，可以方便手动调节卡盘拧紧程度，问题在于结构稍微复杂，针对大型工件的夹持需相应提高装置的比例，导致调整的摩擦力增大，不利于装配及装卡。
总体来说，传统的三爪卡盘、多爪卡盘夹持机构因自身对工件受力不均匀的天然缺陷，使得装配过程中有可能对工件表面产生不可修复的损伤。而且越来越多大型、超大型环形设计的工件不断出现，传统的三爪卡盘、多爪卡盘夹持机构的体积应随着圆环外径的增大而相应增长，在经济成本上越发不占优势，同时反而限制设计人员对大型环工件的设计。
因此，设计一款能克服传统卡盘结构的缺点，并同时有稳定性高、定位精确、对工件表面损伤小等优点的夹持装置，对精密装配制造业具有重要意义。
发明内容
本发明的目的就是针对上述现有技术存在的问题，结合实际需求，设计提供一种气动式精密环形工件内定位面夹持装置，达到提高精密环形工件加工质量、适应能力强、使用方便的目的。
本发明的技术方案是：
在筒身的上、下端面上分别紧密固装上板和下板，楔形块固定配装在上板上，在筒身内部构成密闭腔室；活塞总成的杆部插装在楔形块中心孔内，活塞总成的活塞部配装在筒身内部构成的密闭腔室内，将密闭腔室分隔成完全隔断的上腔室和下腔室，在活塞总成的活塞部位外圆表面上配装密封圈，叠簧套装在活塞总成上，且位于筒身上腔室内，所述叠簧的上端面与上板下端面接触配合，叠簧的下端面通过垫圈与活塞总成的活塞部接触配合，在下板上设置与筒身下腔室连通的进气孔，在筒身上部设置与筒身上腔室连通的排气孔；可以沿径向方向收缩或扩张的弹性铰链块套装在楔形块上侧外部上，限位圈嵌套在弹性铰链块外部上；在活塞总成的杆部上端部上通过预紧螺钉固装转接板，所述转接板与弹性铰链块固接，通过螺纹配合将调整旋钮配装在转接板上，限位螺钉和限位柱插装在转接板上，且限位螺钉和限位柱与楔形块螺纹连接，至此构成气动式密封环形工件内卡夹持装置。
本发明的技术创新性及产生的良好效果在于：
以空气为介质，利用空气的压缩性，实现集中供气，机械设计及维护大大简化；施力均匀，减少受力不均产生的非线性影响；可实现工作速率的智能控制，输入及输出力矩和工作速度的容易调节；结构简单、轻便、安装维护简单，制造成本低，可靠性高，使用寿命长，可实现缓冲。
附图说明
附图是气动式精密环形工件内定位面夹持装置整体示结构意图。

具体实施方式
下面结合附图对本发明具体实施例作进一步详细描述。
一种气动式精密环形工件内定位面夹持装置，在筒身15的上、下端面上分别紧密固装上板14和下板1，楔形块12固定配装在上板14上，在筒身15内部构成密闭腔室；活塞总成5的杆部插装在楔形块12中心孔内，活塞总成5的活塞部配装在筒身15内部构成的密闭腔室 内，将密闭腔室分隔成完全隔断的上腔室和下腔室，在活塞总成5的活塞部位外圆表面上配装密封圈2，叠簧3套装在活塞总成5上，且位于筒身15上腔室内，所述叠簧3的上端面与上板14下端面接触配合，叠簧3的下端面通过垫圈13与活塞总成5的活塞部接触配合，在下板1上设置与筒身15下腔室连通的进气孔1-1，在筒身15上部设置与筒身15上腔室连通的排气孔15-1；可以沿径向方向收缩或扩张的弹性铰链块6套装在楔形块12上侧外部上，限位圈4嵌套在弹性铰链块6外部上；在活塞总成5的杆部上端部上通过预紧螺钉8固装转接板11，所述转接板11与弹性铰链块6固接，通过螺纹配合将调整旋钮9配装在转接板11上，限位螺钉7和限位柱10插装在转接板11上，且限位螺钉7和限位柱10与楔形块12螺纹连接。
作业使用时，压缩空气经由进气孔1-1输入筒身15的下腔室内，活塞总成5压缩叠簧3，并推动活塞总成5做功，带动转接板11、弹性铰链块6向上运动，同时将筒身15的上腔室内空气经排气孔15-1排出，使得弹性铰链块6与楔形块12脱离接触，弹性铰链块6收缩，外圈与圆环形工件脱离接触，实现装置与工件的分离；移除压缩空气后，叠簧3弹力对外做功，推动活塞总成5向下运动，进而使弹性铰链块6与楔形块12重新受压，接触面的径向分力使弹性铰链块6向外扩张，外圈与圆环形工件再次压紧，实现装置与工件的装卡。
所述的气动式精密环形工件内定位面夹持装置里，限位螺钉7用于限制活塞总成5向上的运动行程，进而限定弹性铰链块6的收缩程度；调整旋钮9与限位柱10配合使用，通过事先设定限位柱10的高度，旋转调整旋钮9使二者接触，继而可以精确限定弹性铰链块6的向外扩张程度；当弹性铰链块6没有限定精确外扩程度的时候，限位圈4起补充限位作用。
