具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型的一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。
如图1所示，本实用新型示出了一种自闭阀多状态测试工装，该测试工装与外部测试机(图中未示出)相连接，以用于辅助外部测试机进行自闭阀的三个状态的检测，分别是检测自闭阀的欠压关闭、中位导通和超压关闭。其中，超压、欠压这两个自闭性能是衡量自闭阀是否符合标准的最关键的指标，关系着管道燃气的使用安全性。
该自闭阀多状态测试工装包括测试台架1，测试台架1上设有固定机构2、夹具机构3、感应机构4、移动机构5、显示机构6和控制器(图中未示出)。其中，控制器与固定机构2、夹具机构3、感应机构4、移动机构5、显示机构6电连接，并控制各个机构的正常运行。
具体的结构如下：
固定机构2用于定位并固定待测自闭阀，包括固定底板2.1、水平滑轨2.2、水平滑块2.3、第一堵头2.4、第二堵头2.5和驱动气缸2.6。水平滑轨2.2固定在固定底板2.1上，水平滑块2.3可沿水平滑轨2.2滑动，水平滑块2.3上设有用于定位并固定待测自闭阀的工位，测试前，只要将待测自闭阀安装到该工位即可。水平滑块2.3的两侧均设有用于堵住自闭阀的第一堵头2.4和第二堵头2.5，第一堵头2.4固定在水平滑块2.3上，且随着水平滑块2.3的水平移动而移动，也就是说待测自闭阀安装到工位上时，待测自闭阀一端就通过第一堵头2.4堵住了，第二堵头2.5通过驱动气缸2.6的驱动作用下水平移动，待测自闭阀安 装到工位上后，驱动气缸2.6伸出气缸杆使得第二堵头2.5将待测自闭阀另一端也堵住了，保证了待测自闭阀的气密性。
移动机构5用于上下移动夹具机构3，如图2和图3所示，包括双头气缸5.1、竖直滑轨5.2、竖直滑块5.3和限位部件5.4。双头气缸5.1的两端均有气缸杆，这两根气缸杆串联形成一根气缸杆，双头气缸5.1可沿这一根气缸杆上下移动。双头气缸5.1上端的气缸杆与测试台架1固定连接，双头气缸5.1下端的气缸杆与竖直滑块5.3连接，竖直滑块5.3在双头气缸5.1的驱动下可沿竖直滑轨5.2上下移动，由于是双头气缸5.1，当双头气缸5.1下端的气缸杆行程不够时，可启动双头气缸5.1上端的气缸杆伸缩，又由于双头气缸5.1上端的气缸杆是固定在测试台架1上的，因此双头气缸5.1相对应于上端的气缸杆运动了，增加了双头气缸5.1的上下运动行程，以满足下方的三种测试状态。
限位部件5.4用于限制双头气缸5.1的竖向行程，包括与双头气缸5.1相连接的限位块5.4.1、用于限制限位块5.4.1竖向移动的限位槽5.4.2。该限位槽5.4.2是通过U型件的U形槽口形成的，限位块5.4.1在该限位槽5.4.2中移动，U型件的U形槽口的内壁对限位块5.4.1起到限制其行程的目的。
如图4，夹具机构3用于抓取待测自闭阀，并在移动机构5的作用下，夹具机构3上下移动以调整待测自闭阀的不同气压状态。具体的，夹具机构3包括与竖直滑块5.3相连接的手指气缸3.1、与手指气缸3.1的两个平行夹爪相连接的两只机械抓手3.2。在移动机构5的双头气缸5.1的作用下，推动竖直滑块5.3上下移动，同时使得手指气缸3.1上下移动，移动到位后，启动手指气缸3.1工作，通过两只机械抓手3.2抓取待测自闭阀的盖帽套，再次启动双头气缸5.1移动以带动待测自闭阀的盖帽套上下移动，调节待测自闭阀的内部气压状态，通过感应机构4进行判断，反馈给外部测试机进行测试。
感应机构4用于监测待测自闭阀的不同气压状态并将监测结果反馈给控制器。感应机构4包括固定在测试台架1上的两个感应器4.1以及一根感应连杆4.2，两个感应器4.1上下堆叠设置，感应连杆4.2的上端可穿设感应器4.1，感应连杆4.2的下端与待测自闭阀相抵，可感应待测自闭阀的气压状态。感应连杆4.2穿过两只机械抓手3.2的手心布设。当感应连杆4.2没有穿设感应器4.1时，说明待测自闭阀处于欠压状态；当感应连杆4.2穿设一个感应器4.1时，说明待测自闭阀处于中位导通状态；当感应连杆4.2同时穿设两个感应器4.1时，说明待测自闭阀处于超压状态。
显示机构6用于显示外部测试机的测试结果，根据不同的测试结果，一般为合格或不合格两个测试结果，指示灯会亮起不同颜色的灯，并且，会伴有不同声音的蜂鸣器发声。
本实用新型自闭阀多状态测试工装的测试原理如下：
首先，将待测自闭阀固定在固定机构2上，并通过第一堵头2.4和第二堵头2.5将待测自闭阀进行气密性堵塞，具体的，待测自闭阀安装到固定机构2上时，第一堵头2.4将待测自闭阀一端堵住，另一端通过启动驱动气缸2.6使第二堵头2.5堵住并压紧待测自闭阀；
其次，启动双头气缸5.1上下移动，从而推动夹具机构3上下移动。夹具机构3移动到位后，启动手指气缸3.1，机械抓手3.2抓取待测自闭阀的盖帽套，并在双头气缸5.1的作用下上下移动以调节待测自闭阀的内部气压状态，通过感应机构4进行判断并始终监测以保证待测自闭阀的气压状态：
当感应连杆4.2没有穿设感应器4.1时，说明待测自闭阀处于欠压状态，如图5；
当感应连杆4.2穿设一个感应器4.1时，说明待测自闭阀处于中位导通状态，如图6；
当感应连杆4.2同时穿设两个感应器4.1时，说明待测自闭阀处于超压状态，如图7；
将上述气压状态反馈给控制器，控制器控制外部测试机进行自闭阀的多状态测试。
最后，外部测试机将反馈结果反馈给显示机构6以显示，一般测试合格亮起绿灯，测试不合格亮起红灯，且，不同的测试结果伴随不同的蜂鸣器发声，以提醒操作人员。
综上所述，本实用新型精确、高效地对自闭阀的三种状态(欠压、中位、超压)的性能进行了测试，其测试效率高，避免了人工调节压力检测不准确、效率低下的问题。整个控制系统实现自动加压、降压等动能，提高了自动化生产下的效率。总之，本实用新型提高了自闭阀超压、欠压性能检测的的测试精度及效率，提高了自闭阀产品的质量及可靠性，有效提高了使用者的用气安全性。
