在进行双面成形焊接工艺试验中,针对圆筒形零件焊接特点,我们试制成了一种适合园筒形零件焊接的双面成形夹具—铜轮式夹具。通过焊接生产实践,这种夹具具有设计简单、操作方便、适应性强等优点。具体结构如图所示。 1.工作原理: 焊接前,将铜轮由悬臂送至焊道下面,然后,悬臂作上升运动,使铜轮贴至筒体。其贴紧程度可由压缩弹簧进行调节。正常焊接时,随着简体的旋转,铜轮本身绕中心轴(螺杆)作自转运动。同时,为弥补简体在加工过程中产生的不园度和椭园度,在转动过程中铜轮可由压缩弹簧来进行自动升降调节,使铜轮与筒
In the double-sided forming welding process test, in view of the welding characteristics of the cylindrical parts, we try to make a double-sided forming fixture suitable for cylindrical parts welding - copper wheel fixture. Through the practice of welding production, this fixture has the advantages of simple design, convenient operation and strong adaptability. The specific structure as shown. 1. Working principle: Before welding, the copper wheel cantilever arm to the weld bead, then, the cantilever for ascending movement, the copper wheel attached to the cylinder. The tightness can be adjusted by the compression spring. Normal welding, with a simple rotation, the copper wheel itself around the central axis (screw) for rotation. At the same time, to make up for the simplified process in the production of non-Park and oval degrees, in the process of turning the copper wheel can be automatically adjusted by the compression spring to lift, so that the copper wheel and tube
