Abstract

本发明公开了一种泵车臂架液压油缸，其特征在于，在缸筒的一端焊接有缸底，导向套设在缸筒的一端内壁上，活塞杆从导向套的内孔插入缸筒的内腔，活塞通过其一侧的锁紧螺栓固定在活塞杆的插入端。通过以上设置，本发明采用耐高压、薄壁的27SiMn作为缸筒，采用硬度高的27SiMn管作为活塞杆，保证油缸性能的同时，又减轻了整体油缸重量，符合轻量化标准要求，降低了企业生产成本。

Description

泵车臂架液压油缸
技术领域
    本发明涉及一种油缸，具体说是一种用于泵车臂架上的液压油缸。
背景技术
目前用于泵车臂架上的油缸，其活塞杆多为实心圆柱结构，这样增加了油缸的重量，不符合轻量化标准要求，且浪费原材料，给企业生产提高了成本。
发明内容
本发明的目的是提供一种重量轻、工作性能稳定的泵车臂架液压油缸。
为了实现上述目的，本发明在缸筒的一端焊接有缸底，导向套设在缸筒的一端内壁上，活塞杆从导向套的内孔插入缸筒的内腔，活塞通过其一侧的锁紧螺栓固定在活塞杆的插入端。所述活塞杆为中空管状结构。
通过以上设置，本发明采用耐高压、薄壁的27SiMn作为缸筒，采用硬度高的27SiMn 管作为活塞杆，保证油缸性能的同时，又减轻了整体油缸重量，符合轻量化标准要求，降低了企业生产成本。
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、缸筒，2、缸底，3、导向套，4、活塞杆，5、活塞，6、锁紧螺栓。
具体实施方式
如图1所示，本发明在缸筒1的一端焊接有缸底2，导向套3设在缸筒1的一端内壁上，活塞杆4从导向套3的内孔插入缸筒1的内腔，活塞5通过其一侧的锁紧螺栓6固定在活塞杆4的插入端。所述活塞杆4为中空管状结构。通过以上设置，本发明保证油缸性能的同时，又减轻了整体油缸重量，符合轻量化标准要求，降低了企业生产成本。
