Abstract

本发明公开了一种装载机动臂液压智能油缸，其特征在于，缸底与缸筒的一端焊接在一起，导向套设在缸筒的另一端内壁上，活塞杆穿过导向套插入缸筒的内部，在活塞杆的插入端拧有活塞。通过以上设置，本发明的活塞杆在动作过程中，带动安装在活塞杆内部的磁环在波导管上移动，产生信号经线路反馈到控制器上，通过液压系统控制流入缸筒内的液压油，达到控制活塞杆的伸出、回缩速度与位移。油缸在伸出、回缩行程末端时不会发生撞击现象，实现了油缸的智能控制，提高油缸的使用寿命和工作效率。

Description

装载机动臂液压智能油缸
技术领域
本发明涉及一种油缸，具体说是一种用于装载机动臂上的液压智能油缸。
技术背景
现阶段工程机械装备发展迅速以向大、精、尖方向发展为趋势。液压油缸作为整个机身的动作执行部分，其性能的好坏对整台机器起着至关重要的作用。目前市场上装载机使用的液压油缸一般都不具备缓冲性能，油缸伸出、回缩动作的精准度及速度的控制主要依靠驾驶员的经验，且油缸在伸出、回缩行程末端速度往往很大，经过反复撞击使用，直接降低了油缸的使用寿命。
发明内容
本发明的目的是提供一种举升动作精准的装载机动臂液压智能油缸。
为了实现上述目的，本发明的缸底与缸筒的一端焊接在一起，导向套设在缸筒的另一端内壁上，活塞杆穿过导向套插入缸筒的内部，在活塞杆的插入端拧有活塞。在所述缸底内部设有电子仓，连接在电子仓一侧的波导管插入活塞杆的中心深孔内，在活塞杆的中心深孔内壁上还设有一磁环。
通过以上设置，本发明的活塞杆在动作过程中，带动安装在活塞杆内部的磁环在波导管上移动，产生信号经线路反馈到控制器上，通过液压系统控制流入缸筒内的液压油，达到控制活塞杆的伸出、回缩速度与位移。油缸在伸出、回缩行程末端时不会发生撞击现象，实现了油缸的智能控制，提高油缸的使用寿命和工作效率。
附图说明
现结合附图对本发明做进一步说明。
图1为本发明的结构示意图。
  图中:1、缸底，2、缸筒，3、导向套，4、活塞杆，5、活塞，6、电子仓，7、波导管，8、中心深孔，9、磁环。
具体实施方式
如图1所示，本发明的缸底1与缸筒2的一端焊接在一起，导向套3设在缸筒2的另一端内壁上，活塞杆4穿过导向套3插入缸筒2的内部，在活塞杆4的插入端拧有活塞5。在所述缸底1内部设有电子仓6，连接在电子仓6一侧的波导管7插入活塞杆4的中心深孔8内，在活塞杆4的中心深孔8内壁上还设有一磁环9。通过以上设置，当活塞杆4往复动作时，安装在活塞杆4内的磁环9产生的磁场与波导管7发出的螺旋状脉冲相交产生磁致伸缩现象，此信号可精确的反馈到控制器上，液压系统控制流入缸筒内的液压油，达到控制活塞杆的伸出、回缩速度与位移。
