Description

Technical Field

[0001] The utility model relates to the technical field of production of civil air defense door frames, and particularly relates to a welding device for civil air defense door frames. Background Art

[0002] Civil air defense is an activity in which the government mobilizes and organizes the people to take air raid prevention and disaster relief measures to prevent and mitigate the harm of disasters. Civil air defense doors are civil air defense protection equipment and are the doors at the entrances and exits of civil air defense projects. During the production of some civil air defense doors, four strip-shaped steel plates need to be welded into a frame shape. When the horizontal steel plate and the vertical steel plate are butt-jointed, it often depends on the naked eye judgment of the operator to determine whether they are flush, relying entirely on subjective feelings. During welding, the butt-joint error is large, seriously affecting the welding quality of the civil air defense door frame, and at the same time, huge safety hazards are also generated.

[0003] In the prior art, the authorized patent with the publication number of CN218517893U discloses a welding frame for a civil air defense door frame, which includes a device base and an adjustment shaft. The top of the device base is provided with an adjustment shaft fixed base, the top of the adjustment shaft fixed base is provided with an adjustment shaft, the top of the adjustment shaft is provided with a welding frame, the outer surface of the welding frame is provided with horizontally symmetrically arranged horizontal positioning jigs, the outer surface of the welding frame is provided with vertically symmetrically arranged vertical positioning jigs, and the vertical positioning jigs are located on both sides of the horizontal positioning jigs. A horizontal positioning instrument is installed on the front of the horizontal positioning jig, and a vertical positioning instrument is installed on one outer wall of the vertical positioning jig. By installing the horizontal positioning jig and the vertical positioning jig, the strip-shaped steel plates are aligned and calibrated, greatly improving the butt-joint accuracy, reducing the butt-joint error, further improving the welding quality of the civil air defense door frame, and the civil air defense door frame has higher safety performance.

[0004] However, when the above technical solution is used, it can only weld civil air defense door frames with specific sizes and cannot be applied to the welding of civil air defense door frames with various sizes, so the applicability is not good. In view of this, we propose a welding device for civil air defense door frames to solve the above-mentioned problems. Summary of the Utility Model
