Description

Technical Field

[0001] The invention relates to the field of welding facilities, and in particular to a seamless welding device for aluminum alloy door and window corner assembly. Background Art

[0002] The main function of aluminum alloy door and window corner assembly is to enhance the stability and wind pressure resistance of doors and windows, while ensuring the service life of doors and windows. The aluminum alloy door and window corner assembly refers to the connection between two or more aluminum profiles during the assembly process of doors and windows. This connection is the key to the stability of the door and window frame.

[0003] However, some special-shaped aluminum alloy doors and windows usually have three reinforcement frames evenly arranged at the top of the arc-shaped frame, and the two are fixed by welding to improve the strength of the frame. However, the existing welding facilities can only weld one connection of the frame at a time. If all three reinforcement frames need to be fixed on the frame, welding must be performed three times, which takes a long time and leads to low welding efficiency. At the same time, workers need to measure and locate before welding to ensure that the three reinforcement frames can be evenly distributed on the top of the frame. The operation process is quite cumbersome and inconvenient to use. Summary of the invention

On the other hand, the joint between the reinforcement frame and the frame can be positioned on the trajectory of the welding gun movement, so as to ensure that the welding gun can smoothly weld the frame and the reinforcement frame together during the movement process, that is, to ensure the normal progress of the welding operation.

[0014] 2. When the gun column drives the welding gun to move for welding, the pressure strip will move synchronously to press on the upper end of the reinforcement frame. At the same time, the ring pressure rail will also rotate, allowing the guide wheel to roll on the inclined surface of the ring pressure rail to drive the pressing ring to move downward, thereby driving the tightening frame to move to push the top ear. At this time, the guide rod slides in the guide shell to guide the top ear, so that the three top ears can expand outward synchronously to firmly press the three reinforcement frames on the frame, so that the two are in close contact, thereby ensuring that no gaps will appear after welding.
