在本实施例中，加压组件4包括加压罩41以及活塞42，加压罩41上设有筒体411，筒体411内滑动连接有活塞42，活塞42的顶部固定连接有驱动杆43，加压罩41上设有检测口412，检测口412位于圆形槽11的外侧。
在本实施例中，漏气检测组件5包括U形管51、固定件52以及接近开关53，U形管51与固定件52固定连接，固定件52固定连接在连接板33底部，U形管51的一端通过气管与检测口412连通，U形管51的另一端密封滑动连接有检测块54，检测块54与U形管51之间通过密封圈密封滑动，就相当于是活塞42的功能，检测块54上方设有管盖55，管盖55与检测块54之间设有复位弹簧56，管盖55上设有排气孔，的检测块54的上方设有与其对应的接近开关53。检测块54采用金属材质，接近开关53采用电感式接近开关53，从而使得接近开关53可以检测到检测块54的靠近信号。
在本实施例中，驱动组件3包括液压缸31、驱动板32以及连接板33，驱动板32与液压缸31的输出轴固定连接，驱动杆43与驱动板32固定连接，加压罩41固定连接在连接板33的底部，驱动板32与连接板33之间的驱动杆43上套设有下压弹簧34，下压弹簧34在连接板33底部不受力的情况下，可以保证连接板33与驱动板32保持相对静止的运动，一旦连接板33运动受限，下压弹簧34在可以增加加压罩41与转盘1的压力同时，不妨碍驱动杆43的继续运动。
在本实施例中，圆形槽11内固定连接有锥台8以及与法兰端盖7配套使用的下密封圈9，锥台8的底面直径与法兰端盖7的内径相同，当法兰端盖7套在凸台的外侧时，法兰端盖7会顺着凸台，在重力以及加压罩41的作用下定位到圆形槽11的中心处，下密封圈9位于锥台8的外侧，加压罩41的底部设有密封 垫413，加压罩41的内底部固定连接有与法兰端盖7配套使用的上密封圈414。法兰端盖7在使用时是需要配合上密封圈414与下密封圈9使用的，所以为了模拟法兰端盖7的使用状态，所以在相应的位置设置上密封圈414与下密封圈9。
工作过程及其原理：
检测时，法兰端盖7通过上料输送带61输送至上料工位处，上料输送带61的末端设置有相应的挡板，来防止法兰端盖7掉出上料输送带61。上料输送带61上方的升降气缸654输出轴伸长带动气胀套655下移至法兰端盖7的中心处，然后气胀套655膨胀将法兰端盖7内撑固定住，升降气缸654输出轴回缩带动法兰端盖7上移。之后在转运气缸652输出轴伸长的带动下，L形板653向着转盘1上圆形槽11处运动，和L形板653固定连接的升降气缸654也跟着运动到圆形槽11的上方，最后升降气缸654输出轴伸长，将法兰端盖7放入到圆形槽11内。
此时的凸台位于法兰端盖7内，使得法兰端盖7自动调整到圆形槽11的中心，圆形槽11内的下密封圈9套在法兰端盖7上，下密封圈9就是法兰端盖7在正常连接时所使用的密封圈。
转盘1在分割器的作用下转动90度，重复以上动作，直到将转盘1上的圆形槽11全部放上法兰端盖7为止。
上料完毕，开始检测，液压缸31带动驱动板32下移，由于驱动板32与连接板33之间设置有下压弹簧34，所以连接板33在底部没有受力的情况下，也同步下移。此时的驱动杆43以及活塞42与加压罩41保持相对静止。当加压罩41下降到与转盘1上表面相接触的同时，也与法兰端盖7的顶面接触，由于此时的加压罩41下降受限，所以连接板33的运动也会受限。
但是驱动板32依然可以正常下降，驱动板32下移，下压弹簧34被不断压缩，加压罩41与转盘1之间以及加压罩41与法兰端盖7之间的压力增大，在密封垫413与上密封圈414的作用下，防护罩内形成两个独立的空腔，一个是防护罩与法兰端盖7上部以及法兰端盖7下部与转盘1、下密封圈9形成的第一个空腔，这个空腔用于充气以及保压，其次是法兰端盖7外部、防护罩以及转盘1形成的第二空腔，这个空腔用于检测是否漏气。
驱动板32下降带动驱动杆43下移，从而使得活塞42在加压罩41的筒体 411内滑动，从而将气从法兰端盖7的中心孔处充入到法兰端盖7内。
当法兰端盖7内部漏气时，气体会进入到第二个空腔内并从检测口412溢出，溢出的空气通过气管进入到U形管51内，由于检测块54与U形管51之间也是通过相应的密封圈进行密封的，所以气压可以推动检测块54上移，检测块54上移到一定程度，就会到达接近开关53可检测到的距离，从而使得接近开关53检测到这一接近信号，从而给后台系统传输这个法兰端盖7不合格的检测结果，并记录。
检测完毕，液压气缸带动驱动板32上移，下压弹簧34复位，迫使驱动杆43上移，活塞42复位，U形管51内释压，检测块54也在复位弹簧56的作用下复位到接近开关53检测不到的距离。之后下料工位处的取件装置65配合直线模组64以及转盘1的旋转将合格的产品放入到合格品输送带63上，不合格的产品放入到次品输送带62上，完成检测后的筛分工作。
基于上述：
上下料装置6可以实现法兰端盖7的自动上下料，满足生产自动化的要求；
加压组件4通过液压缸31的驱动，即可同时实现对法兰端盖7所在区域的密封以及对法兰端盖7内部的充气功能，无需增加额外的气源组件，减少了设备成本，缩短了检测时长；
漏气检测组件5采用气压变化来驱动检测块54移动，从而满足接近开关53可检测的距离，此过程相应速度快，准确率高，不会出现人为观察出错的情况；
转盘1配合加压组件4以及漏气检测组件5使用，可同时对多个法兰端盖7进行检测，大幅缩短了检测周期，适用于大批量的检测工作。
由技术常识可知，本发明可以通过其它的不脱离其精神实质或必要特征的实施方案来实现。因此，上述公开的实施方案，就各方面而言，都只是举例说明，并不是仅有的。所有在本发明范围内或在等同于本发明的范围内的改变均被本发明包含。
