Problems solved by technology

[0002] The welding requirements of the fishplate parts in the existing piece standard section are relatively high, which requires not only the coaxiality of the through holes on the two relative fishplates but also the distance between the two relative fishplates, and the fishplates need to be welded At the end of the main limb of the chip standard joint, there are many and complicated welds, and in most cases it is welded manually, but manual welding will not only waste a lot of manpower, but also make the chip standard joint unable to be automatically processed and produced
[0003] If a welding robot is used for welding, multiple steps such as positioning riveting, welding, and repair welding are required. After positioning riveting, due to handling and other problems, the fishplate often has a certain offset, resulting in problems such as failure to meet the target requirements. Welding quality is poor, lower pass rate

Embodiment 1

[0035] Such as figure 1 As shown, the fishplate welding accompanying tooling of this embodiment is used between the riveting station and the repair welding station of the fishplate automatic welding production line, and includes a distance fixing device 1 and a fixing device 1 for fixing the distance between the inner and outer fishplates. The coaxiality fixing device 2 of the coaxiality of the through hole 3 on the opposite inner and outer fishplates. When the fishplate parts arrive at the riveting welding station of the automatic welding production line, the positioning riveting welding is carried out first, and then the distance fixing device 1 and the coaxiality fixing device 2 are installed to completely fix the fishplate relative to the main limb, so that the fishtail The plate will not be shifted during the handling process from the riveting station to the welding station, from the welding station to the repairing station, and during the welding process, which improves ...

Embodiment 2

[0042] This embodiment is basically the same as Embodiment 1, the only difference is that, as Figure 4 As shown, the space-avoiding area 14 on the distance fixing device 1 of the present embodiment is a U-shaped through groove whose circular arc part corresponds to the position of the through hole 3 and whose diameter is not less than the diameter of the through hole 3. The U-shaped through groove is along the through hole. 3 Axially penetrate the spacing fixing device 1, the opening of which faces the fixed end of the fishplate. The distance fixing device 1 with such an avoidance area 14 can be installed before the coaxiality fixing device 2 and then removed after the coaxiality fixing device 2, or can be installed after the coaxiality fixing device 2 and preceded by the coaxiality fixing device 2. The axiality fixing device 2 is removed, and the assembly and disassembly process is more random, which expands the scope of application. In other embodiments, it is also possibl...

Embodiment 3

[0044] This embodiment is basically the same as Embodiment 1 and Embodiment 2, the only difference is that, as Figure 5 As shown, the coaxiality fixing device 2 of this embodiment is a taper pin, wherein: the shaft body 21 is provided with a tapered shaft section located inside the first blocking step 211 and corresponding to the position of the fishplate on one side, and the end The sleeve 22 is provided with a tapered shaft section located inside the second blocking step 221 and corresponding to the fishplate on the other side. When the end sleeve 22 is fastened to the external threaded end, the tapered shaft section can automatically center the inner and outer fishplates, and is more convenient for disassembly and assembly, further improving the fixing effect and disassembly efficiency.

Abstract

The invention discloses a welding accompanying tool of a fish plate. The welding accompanying tool of the fish plate is used between a riveting welding station and a repair welding station of a fish plate automatic welding production line, comprises a distance fixing device used for fixing the distance between an inner fish plate and an outer fish plate, and a coaxiality fixing device used for fixing the coaxiality of through holes in the inner fish plate and the outer fish plate. The welding accompanying tool of the fish plate has the advantages of being simple, practical, convenient to assemble and disassemble, capable of realizing automatic welding of the fish plate, and improving the welding quality.

Description

technical field [0001] The invention relates to the field of welding tooling, in particular to a fishplate welding accompanying tooling. Background technique [0002] The welding requirements of the fishplate parts in the existing piece standard section are relatively high, which requires not only the coaxiality of the through holes on the two relative fishplates but also the distance between the two relative fishplates, and the fishplates need to be welded At the end of the main limb of the piece standard joint, there are many and complicated welds, and in most cases it is welded manually, but manual welding will not only waste a lot of manpower, but also prevent the automatic processing and production of the piece standard joint. [0003] If a welding robot is used for welding, multiple steps such as positioning riveting, welding, and repair welding are required. After positioning riveting, due to handling and other problems, the fishplate often has a certain offset, resul...
