如图1-3所示，一种埋弧焊焊枪角度调节装置，包括支架，支架上连接有行走机构，行走机构连接有焊枪1，支架上设有滑轨，行走机构与滑轨滑动连接。
使用过程中，焊枪1通过行走机构带动，可在支架上滑动移动，进而完成焊枪1角度的调节，具体的，支架包括弧形板2，弧形板2的一条弧形边为滑轨，其上设有滑动组件，另一条弧形边上驱动组件；

具体使用时，在焊接过程中，当需要进行焊枪1角度调节时，转动驱动齿轮5，驱动齿轮5固定在支撑板3上，驱动齿轮5与齿条10相互转动产生位移，其中，弧形板2固定不动，进而使得驱动齿轮5驱动支撑板3移动，在支撑板3的顶部的滑轮4沿弧形板2的侧边滚动，调节支撑板3移动，可将支撑板3上的焊枪1调节带动至所需位置。
其中，将滑轨设置为弧形结构，利于角度改变，该埋弧焊焊枪角度调节装置，可在焊接过程中使用，可快速准确的调节焊枪1到所需角度，使用更加方便。

锁紧组件为锁紧手柄8，锁紧手柄8包括手柄本体及螺杆，设于弧形板2远离支撑板3的一侧，螺杆穿过弧形孔7与支撑板3固定连接，手柄本体上设有锁紧螺母，锁紧螺母的外径大于弧形孔7的宽度。
支撑板3与弧形板2之间通过锁紧组件连接，锁紧组件的作用是对支撑板3进行固定，当焊枪1移动至所需位置后，将支撑板3和弧形板2锁紧，避免焊枪1随意移动，确保焊接的正常运行。
具体的，螺杆连接在支撑板上，且穿设过弧形孔7，手柄本体转动，可带动锁紧螺母一同转动，锁紧螺母的外径较大，锁紧螺母旋紧状态时，锁紧螺母 压紧弧形板2，对支撑板3和弧形板2进行限位，避免两者相对移动。当需要调整时，旋转手柄本体，将锁紧螺母旋松，支撑板3和弧形板2可相对移动。
支架还包括安装架9，安装架9与弧形板2连接，安装架9上设有安装孔。
该埋弧焊焊枪角度调节装置，整体通过安装架9与埋弧焊机主体连接。
本发明还提供了一种埋弧焊机，包括上述埋弧焊焊枪角度调节装置。
埋弧焊机，可快速调节焊枪1的焊接角度，适用范围更广，适用于平对接焊缝、横对接焊缝，平位置角焊缝、横位置角焊缝等多个位置的焊接。
具体操作方法为：
1、首先旋转锁紧螺母，松开锁紧组件，然后旋转手轮6，使行支撑板3在驱动齿轮5的驱动下，在弧形板2上移动；
2、根据焊缝坡口和坡口角度，将焊枪1移动至所需位置后，旋转锁紧螺母，锁紧螺母将支撑板3和弧形板2锁死，此时即可进行焊接操作。
3、焊接过程中可根据坡口变化随时锁紧螺母及旋转手轮6进行焊枪1角度调节来保证焊缝成型与焊接质量。
其优点为：增大了焊枪1调节角度，使现有埋弧焊机可用于横位置角焊缝焊接，替代原有的CO2半自动焊接，提高了焊接效率，降低了劳动强度。焊接过程中可根据坡口角度快速调节焊枪1角度，改善了焊缝成型与焊接质量。将现有普通埋弧焊的适用范围扩大至横对接焊缝、小角度横位置角焊缝，平位置角焊缝等焊缝，实现了埋弧焊机的一机多用。
以上结合具体实施例描述了本发明的技术原理。这些描述只是为了解释本发明的原理，而不能以任何方式解释为对本发明保护范围的限制。基于此处的解释，本领域的技术人员不需要付出创造性的劳动即可联想到本发明的其它具体实施方式，这些方式都将落入本发明的保护范围之内。
