Description

一种角焊小车 技术领域
本实用新型涉及焊接设备技术领域，具体涉及一种角焊小车。
背景技术
自动角焊小车在船舶行业以及其它钢结构行业应用非常广泛，其代替了人手持枪进行操作，降低了劳动强度，提高了焊接效率和焊接质量。自动角焊小车在车体上设置焊枪夹持机构，焊枪夹持机构上夹持焊枪，工作时通过移动小车位置实现角接缝的焊接。
如图1所示，现有的角焊小车其焊枪夹持机构旋转设置，采用该焊枪旋转的方式使得焊枪能够到达两侧的角接缝位置，进一步实现无盲区焊接。旋转设置会引起一个质量问题，即焊枪在焊接两侧缝时焊枪的角度各不相同，其旋转的速度与正常的焊接速度也不匹配，导致两侧的角焊缝质量不满足要求，一般会存在焊脚偏小(小车本身无法调节使其达到正常焊缝尺寸)、偏焊、熔深尺寸不足、焊缝成型不美观等问题，大部分需要进行加焊一道才能满足要求，从而中增加了焊接工时；此外，该小车内部零件设计精密，故障率也很高，维修费用增加。
实用新型内容

作为本实用新型的一个优选方案，所述驱动结构包括轴承导轮，所述轴承导轮上套设有心轴，所述心轴一端套设有滚动轴承，另一端套设有关节轴承。
作为本实用新型的一个优选方案，所述滚动轴承上焊接所述焊枪夹持机构，所述关节轴承的螺纹端连接电动缸的活塞杆。
作为本实用新型的一个优选方案，所述凹槽呈条形状。
作为本实用新型的一个优选方案，所述车体上设有控制盒，所述控制盒用于控制所述角焊小车的滑动速度与焊接速度相同。
作为本实用新型的一个优选方案，所述焊枪夹持机构为呈环形状的卡勾或三爪机械手。
本实用新型的有益效果为：
本实用新型的角焊小车包括车体、在车体上设置的焊枪夹持机构以及驱动结构，其中，车体上沿滑动方向开设有凹槽，驱动结构能驱动焊枪夹持机构在凹槽内移动；工作时，焊接小车置于待焊接型材的一端，该焊接小车车体不动，焊枪夹持机构沿着凹槽从一端移动至另一端，当其移动至凹槽的另一端时，焊枪夹持机构停止移动，焊接小车开始进行滑动，直至滑动至待焊接型材的另一端，完成整条平角焊缝的焊接；该焊接小车能提高焊缝的焊接质量，解决了目 前的焊接小车焊接质量差、需要加焊一道工序才能完成焊接的问题，此外，焊接小车结构简单、故障率较低。
