Technical Field

[0001] This utility model relates to the field of welding technology, specifically to an auxiliary welding platform for fireproof door frames. Background Technology

[0002] Fire doors are doors that meet the requirements of fire resistance stability, integrity, and thermal insulation for a certain period of time. They are fire-resistant partitions with a certain degree of fire resistance, installed in fire compartments, evacuation stairwells, vertical shafts, and other similar locations. In building construction, they are specifically used to isolate fire sources and play a vital role in firefighting, providing people with an escape route in the event of a fire.

[0003] Existing fire door frame welding devices mostly use welding platforms for auxiliary welding when welding door frames. However, the clamping structure on the existing auxiliary welding platform cannot be changed according to the different shapes of the fire door frame. Therefore, it is easy for the fire door frame components to be misaligned when fixing them, resulting in deviations in the welding of the fire door frame components and deformation of the fire door frame after welding.

There are four moving structures on the worktable 1, with the moving structures on both sides forming one group and the moving structures at both ends forming another group. The lengths of the lead screw 6 in the two groups of moving structures are different.

[0040] In this embodiment, the clamping structure 8 includes a mounting plate 81, which is disposed on the surface of the lead screw 6.
