Embodiment 1

[0039] see Figure 1 to Figure 9 A general welding tool for the corbel of a subway rail vehicle includes a frame 1, a corbel pressing device 2, a longitudinal limiting device 3, a transverse limiting device 4 and a reference adjustment device 5; the corbel pressing device 2 is arranged on the frame 1 on ( figure 1 Among them, four sets of bolster pressing devices 2) are respectively arranged on the two long sides of the frame. On one side in the width direction, the reference adjustment device 5 is located on the inner side of the frame, and the reference adjustment device 5 is provided in one-to-one correspondence with the beam pressing device 2 to adjust the placement height of the beam. Both the longitudinal limiting device 3 and the lateral limiting device 4 are provided with two groups.

[0040] Such as Figure 4 As shown, the frame 1 includes a crossbeam 1.1 and a longitudinal beam 1.2, and the crossbeam 1.1 and the longitudinal beam 1.2 are connected end to end to fo...

Abstract

The invention provides a universal welding tool for a sleeper beam of a subway rail vehicle, comprising a frame, a sleeper beam pressing device, a longitudinal limiting device, a transverse limiting device and a reference adjusting device; the sleeper beam pressing device is arranged on the frame to press the sleeper beam, the longitudinal limiting device is arranged on the frame to limit the sleeper beam in a longitudinal direction, the transverse limiting device is arranged on the frame to limit the sleeper beam in a transverse direction, the reference adjusting device is positioned on the inner side surface of the frame, and the reference adjusting device corresponds to the sleeper beam pressing device one by one to adjust the placing height of the sleeper beam. The invention relates toa welding method for a sleeper beam of a subway rail vehicle, which comprises the following steps of adjusting too before welding, welding and assembling the sleeper beam, and standing after weldingto eliminate stress. The welding tool provided by the invention has a simple structure, novel design, convenient operation and strong universality; double functions of workpiece positioning and welding deformation reduction are simultaneously realized by matching the welding method, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of subway rail trains, in particular to a universal welding tool for a subway rail vehicle corbel and a welding method thereof. Background technique [0002] As the most critical component of a subway rail train, the corbel is the platform connecting the train body and the bogie, which transmits the vertical load and transmits the driving force of the bogie to the entire car body. The welds of the bolster beams are all thick plate welds, and the main structure is made of aluminum alloy, which will cause shrinkage and deformation in the horizontal and vertical directions of the structure, and the amount of shrinkage is difficult to control. The quality requirements for welding of subway rail vehicles are very strict. How to improve the quality, dimensional accuracy and welding efficiency of aluminum alloy car bodies after welding has always been a key problem in the continuous improvement of aluminum alloy fi...
