Embodiment
[0034]The side beam 5 welded in this embodiment welds and fixes two parallel and opposite side beam vertical plates through a plurality of side beam partitions, forming a side beam structure with a concave middle and raised ends. The partition has different degrees of inclination. The side beam structure ensures that the bearing capacity can be evenly distributed when the side beam is stressed, avoiding stress concentration at the welding part of the side beam partition and reducing the welding life.
[0035] Such as figure 1 As shown, in order to weld the above-mentioned side beam structure, the present embodiment provides a kind of tooling equipment for welding the side beam of the subway bogie frame, including an assembly platform 1, a side beam 5 placed on the assembly platform 1, a set of equipment The central positioning mechanism 2 in the middle of the side beam 5 , two sets of end positioning mechanisms 3 located at both ends of the side beam 5 and a plurality of side ...

The invention relates to a tooling equipment for welding side beams of subway bogie frames, which includes a side beam partition plate positioning seat, and is characterized in that: the side beam partition plate positioning seat includes a fixed base, a positioning plate, a positioning bolt and a support The fixed base is fixed horizontally, and its upper surface is movably connected with one end of the positioning plate; the support arms are respectively movably connected with the positioning plate and the fixed base, and the side of the positioning plate surface close to the movable connection part is provided with A fixed plate perpendicular to the surface of the positioning plate, on which a pair of positioning bolts are arranged. The invention solves the problem of poor positioning accuracy and low welding efficiency of the inclined side beam partition in the existing welding tool, improves the versatility of the positioning seat of the side beam partition, improves the positioning accuracy of the partition, and improves the welding efficiency. efficiency.
Description
technical field [0001] The invention relates to the technical field of welding equipment, in particular to a tooling equipment used for welding side beams of subway bogie frames. Background technique [0002] The bogie is one of the most important components in the rail vehicle structure and plays an important role in the rail vehicle structure: first, it supports the car body, bears and transmits the load from the car body to the wheel or from the wheel rail to the car body Various loads and forces, and evenly distribute the axle load; second, it is easy to install the spring damping device, so that it has good vibration damping characteristics, so as to ease the interaction between the vehicle and the line, reduce vibration and impact, Reduce the dynamic stress and improve the running stability and safety of the vehicle. Therefore, whether the structure of the bogie is stable also directly determines the stability of the vehicle and the ride comfort of the vehicle. [000...
