Description

Technical Field

[0001] The present application relates to the technical field of welding positioning, and in particular to a welding positioning tool for a long plate. Background Art

[0002] Aerial platform is a kind of high-altitude operation equipment used in warehousing and logistics. It is similar to an escalator, which can facilitate personnel standing on the platform to store and retrieve goods. Aerial platform is made up of various parts, and each part is welded by aluminum alloy or iron. In order to achieve a good splicing effect between the various parts of the aerial platform, when welding each part, it is necessary to ensure that the welding size is consistent with the pre-set size. Figure 1 , multiple parts are the first workpiece 40, and the long strip is the second workpiece 50. In the production and assembly of the aerial platform, multiple first workpieces 40 need to be welded to the second workpiece 50. The first workpieces 40 are respectively provided with limiting holes. During welding, it is necessary to ensure that the limiting holes of each first workpiece 40 are on the same axis, so that during assembly, the assembly accuracy between the second workpiece 50 and the adjacent second workpiece 50 is good.

[0003] However, in the prior art, when welding the first workpiece 40 to the second workpiece 50 , the multiple first workpieces 40 are all provided with abutment surfaces, and the abutment surface of each part is respectively contacted with the long strip, thereby completing the welding between the multiple first workpieces 40 and the second workpiece 50 .

[0004] With respect to the above-mentioned related technologies, the inventors believe that when multiple first workpieces 40 are welded to the second workpiece 50 one after another, it cannot be ensured that the multiple first workpieces 40 are on the same axis, resulting in low coaxiality between the multiple first workpieces 40, which in turn will cause the multiple first workpieces 40 on the second workpiece 50 to be unable to be assembled with other parts, thereby making the assembled aerial platform low in precision.
