Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, specifically to a column welding tooling. Background Technology

[0002] In modern rail transit construction, the support columns serve as crucial supporting structures, and their manufacturing and installation quality directly impacts the safety and stability of the entire rail transit system. However, existing rail transit support columns, due to their large diameter and length, present numerous challenges to construction. Traditional manual positioning and clamping methods are no longer adequate for the welding requirements of these long columns. In practice, problems such as inaccurate welding positioning and insecure clamping frequently occur, leading not only to a decline in welding quality but also severely impacting project progress and efficiency.

[0003] Specifically, due to the large size of the columns, manual positioning is prone to errors, causing welding points to be out of place and affecting the stability and safety of the overall structure. Furthermore, traditional clamping methods often fail to provide sufficient clamping force for long columns, making them prone to displacement during welding and further impacting weld quality. Even more seriously, once one side of the column is welded, the lack of an effective switching mechanism prevents operators from easily switching to the other side for welding, increasing construction complexity and significantly extending the construction period.

[0025] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0026] Example 1

[0027] like Figure 1-5 As shown, this utility model discloses a column welding fixture, including a transverse frame 1, a longitudinal frame 2, support components, a connecting beam 3, a positioning horizontal plate 4, and a positioning vertical plate 5; a plurality of longitudinal frames 2 are arranged between the two transverse frames 1; a plurality of support components are arranged on the transverse frames 1; two connecting beams 3 are inserted into the tail end of the transverse frames 1; two positioning horizontal plates 4 are arranged at the tail end of the connecting beams 3; and two positioning vertical plates are fixedly connected to the positioning horizontal plates 4.

[0028] Furthermore, there are at least two support components.

[0029] Furthermore, the support assembly includes two support plates 6 and guide wheels 7; the guide wheels 7 are disposed between the two support plates 6.

[0030] Furthermore, the supporting plate 6 is composed of a triangular plate 8 and a limiting plate 9 welded together; the supporting cross section of the limiting plate 9 is "U" shaped; threaded holes are respectively provided at both ends of the opening of the limiting plate 9.

[0031] Furthermore, the guide wheel 7 and the two support plates 6 are threaded together by bolts and nuts.

[0032] Furthermore, the positioning horizontal plate 4 and the positioning vertical plate 5 are welded together; threaded holes are respectively provided at both ends of the positioning horizontal plate 4.

[0033] Furthermore, the insertion beam 3 is provided with a plurality of equally spaced threaded holes; the tail end of the transverse frame 1 is provided with a plurality of threaded holes with the same spacing as those on the insertion beam 3; and the tail end of the insertion beam 3 is provided with threaded holes.

[0034] Furthermore, the positioning cross plate 4 and the insertion beam 3 are threaded together by bolts and nuts.

[0035] Furthermore, the two plug beams 3 and the two transverse frames 1 are threaded together by bolts and nuts.

[0036] Furthermore, there are at least two sets of bolts and nuts connecting the two plug beams 3.

[0037] It should be noted that the column is hoisted and placed on the support assembly, and the tail end of the column is positioned and fixed using the plug-in beams. Then welding is performed. After welding one side is completed, the bolts and nuts on the two plug-in beams are loosened, the plug-in beams are removed, and the workpiece is rotated using the guide wheels inside the support assembly. After rotating to the other side of the workpiece, the plug-in beams are inserted into the horizontal frame and moved to the workpiece position. Then the bolts and nuts on the plug-in beams are tightened for positioning, and then the other side of the workpiece is welded.

[0038] Example 2

[0039] The difference between this embodiment and Embodiment 1 above is that: Figure 6-8 As shown, when the workpiece size is smaller than the distance between the two interlocking beams 3, a pad 10 is added to the tail end of the workpiece to keep it in a horizontal state before welding. After welding one side of the workpiece, the pad 10 is removed, and the workpiece is rotated using the guide wheel 7 in the support assembly. After rotating to the other side of the workpiece, the pad 10 is placed at the tail end of the workpiece for welding. The entire operation can be completed without moving the interlocking beams.
