The invention provides a train positioning auxiliary device for skirting board welding, and relates to the technical field of high-speed train aluminum alloy skirting board welding. The train positioning auxiliary device for skirting board welding comprises a rack, a plurality of rapid clamps, a plurality of positioning baffles, two I-shaped bases, a plurality of front bottom supports, a pluralityof end adjustment beams, a plurality of groups of adjustment units, a plurality of bottom adjustment beams, a plurality of stiffening beams, a plurality of elastic compression beams, a plurality of rear bottom supports and two clamping arms. The train positioning auxiliary device for skirting board welding can control the deformation amount in the welding process of aluminum alloy skirting boards, the bottom adjustment beams with adjustable radians are adopted to clamp, the train positioning auxiliary device for skirting board welding is suitable for the skirting boards with different arc-shaped sizes, the adjustable end adjustment beams are used and a water cooling mode is adopted to control the heat conduction in the welding process, so that the welding deformation amount is controlled,the skirting boards are not required to be waited for cooling after welding, workpieces can be discharged, the whole production efficiency is greatly improved, the wasting of resources is reduced, and potential quality hazards are reduced.
Description
technical field [0001] The invention relates to the technical field of aluminum alloy skirt plate welding of high-speed EMUs, in particular to an auxiliary device for welding and positioning train skirt plates. Background technique [0002] Such as figure 1 and figure 2 As shown, the rail high-speed bus skirt 15 is an aluminum welded structure composed of the upper profile 15-1 and the lower profile 15-2. There are big differences. The manufacturing process is: assembling, welding, and repairing. Since the radians of different types of skirt plates are different, when the model is changed, it is necessary to make a new welding clamping device. It is not universal, the cycle is long, and the work efficiency is low. high cost. In addition, due to the large deformation of the aluminum alloy after welding, it is often necessary to use the adjustment shim to adjust the preset anti-deformation during the welding process. , if the welding deformation is not properly controlle...
