Description

智能调节夹紧力油缸 技术领域
本发明涉及液压夹具技术领域，尤其涉及一种智能调节夹紧力油缸。
背景技术
现代社会的工业发展是以加工设备的自动化程度和机器人取代人工的广泛程度来衡量的。液压夹具——液压缸在其中扮演了重要的角色。目前使用的液压油缸无论是直线式或转角式，由于设计上的缺陷，在当前已经不能满足快速发展的机械自动化和机械人领域的需求。在以往的实际使用中还发现，目前液压油缸的气检结构在设计上虽然可以避免机械加工中的误操作，但由于结构复杂，不仅制造成本高，而且由于质量难以保证，产品的误动作还是会时有发生。
发明内容
本发明为解决上述问题，提供一种智能调节夹紧力油缸。
为解决上述技术问题，本发明的技术方案是：智能调节夹紧力油缸，包括底座、下泵体、上泵体、压紧杆、信号放大电路板、传感器头、油堵、活塞、进油口、传感器触头板和出油口；底座内安装有信号放大电路板，底座上安装有下泵体，下泵体上安装有上泵体；下泵体与上泵体之间的内腔通过油堵分为上腔室和下腔室，油堵固定在上泵体的内壁上；活塞包括依次相连成一体式结构的活塞上杆、活塞头和活塞下杆；活塞上杆和活塞头位于上腔室，且活塞上杆的顶部伸出上泵体，活塞上杆与上泵体之间密封，活塞头与上泵体之间密封，压 紧杆固定安装在活塞上杆的顶部；活塞下杆穿过油堵伸入下腔室，且活塞下杆与油堵之间密封；传感器触头板固定安装在传感器座上，传感器触头板和传感器座均位于下腔室，传感器头的一端固定在活塞下杆的底部，另一端位于传感器触头板内；上泵体的壁内开设有进油口、出油口，进油口、出油口均与上腔室连通。
优选的，底座上通过连接螺栓安装有下泵体。
优选的，压紧杆通过紧定螺母、调节螺栓固定安装在活塞上杆的顶部。
优选的，活塞上杆与上泵体之间通过密封圈一密封。
优选的，活塞上杆与密封圈一之间安装有防尘圈，且防尘圈位于密封圈一的上方。
优选的，活塞头与上泵体之间通过密封圈二密封。
优选的，活塞下杆与油堵之间通过密封圈三密封。
优选的，传感器座通过固定螺栓与下泵体连接。
本发明可以随时停止或随时启动，且由于有随机信号，油缸的动作可以在显示屏上清晰的显示，随时可以调整其工作状态，使油缸可以达到智能控制，突破了液压机器人的关键技术。

图6是图5的A-A向视图。
其中：1、底座，2、下泵体，3、上泵体，4、压紧杆，5、紧定螺母，6、调节螺栓，7、连接螺栓，8、信号放大电路板，9、传感器头，10、密封圈三，11、油堵，12、密封圈二，13、密封圈一，14、活塞上杆，15、防尘圈，16、进油口，17、活塞头，18、传感器触头板，19、传感器座，20、固定螺栓，21、出油口。
具体实施方式
如图1-图6所示，智能调节夹紧力油缸，包括底座1、下泵体2、上泵体3、压紧杆4、信号放大电路板8、传感器头9、油堵11、活塞、进油口16、传感器触头板18和出油口21；底座1内安装有信号放大电路板8，底座1上通过连接螺栓7安装有下泵体2，下泵体2上安装有上泵体3；下泵体2与上泵体3之间的内腔通过油堵11分为上腔室和下腔室，油堵11固定在上泵体3的内壁上；活塞包括依次相连成一体式结构的活塞上杆14、活塞头17和活塞下杆；活塞上杆14和活塞头17位于上腔室，且活塞上杆14的顶部伸出上泵体3，活塞上杆14与上泵体3之间通过密封圈一13密封，活塞上杆14与密封圈一13之间安装有防尘圈15，且防尘圈15位于密封圈一13的上方，活塞头17与上泵体3之间通过密封圈二12密封，压紧杆4通过紧定螺母5、调节螺栓6固定安装在活塞上杆14的顶部；活塞下杆穿过油堵11伸入下腔室，且活塞下杆与油堵11之间通过密封圈三10密封；传感器触头板18固定安装在传感器座19上，传感器座19 通过固定螺栓20与下泵体2连接，传感器触头板18和传感器座19均位于下腔室，传感器头9的一端固定在活塞下杆的底部，另一端位于传感器触头板18内；上泵体3的壁内开设有进油口16、出油口21，进油口16、出油口21均与上腔室连通。工作原理：当进油口16进入压力油时，压力油会沿着油路到活塞头17的下端推动活塞头17向上运动；活塞头17上部腔内的油通过出油口21回到油箱。这个运动过程中，活塞下杆带着传感器头9向上运动。当传感器头9接触到传感器触头板18的上部，信号放大电路板8会把信号传送到自动控制系统，自动控制系统会发出指令到伺服电机，电机反转，这时压力油会通过出油口21进油，推动活塞头17向下运动。这个运动过程中，活塞下杆带着传感器头9向下运动。当传感器头9接触到传感器触头板18的下部，信号放大电路板8会把信号传送到自动控制系统，自动控制系统会发出指令到伺服电机，电机正转，再次完成上一个循环运动。智能油缸就是在这样的往复运动中完成对工件夹紧、松开的工作。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明披露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
