Embodiment Construction
[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0016] Such as Figure 3 to Figure 5 As shown, the rail passenger car bogie longitudinal beam assembly repair tooling of the present invention includes: a bottom platform 1, a turbo pump 2 for supporting the longitudinal beam assembly 5, a pressure head mechanism 3 and a pressing rod for pressing the longitudinal beam assembly 5 4. The turbo pump 2 and the pressure rod 4 are placed in the middle of the bottom platform 1, and the bottom of the pressure head mechanism 3 is fixedly connected to the four corners of the bottom platform 1.
[0017] The number of turbo pumps 2 is two, and the turbo pumps 2 are used to support the upper cover plate 5 - 1 of the longitudinal beam assembly 5 . The number of pressing head mechanisms 3 is four, and the pressing head mechanisms 3 are used for pressing the upper cover plate 5 - 1 of the longitudinal beam assembly 5 .

The invention discloses a railway passenger car bogie longitudinal beam assembly adjusting and repairing tool, and relates to the technical field of railway passenger car bogie adjusting and repairing. The tool comprises a bottom platform, a turbine pump which is used for supporting a longitudinal beam assembly, pressing head mechanisms which are used for tightly pressing the longitudinal beam assembly and a pressing rod, the turbine pump and the pressing rod are placed in the middle of the bottom platform, and the bottoms of the pressing head mechanisms are fixedly connected to the four corners of the bottom platform. According to the tool, the stability and reliability of the longitudinal beam assembly during clod adjusting and repairing are ensured, the adjusting and repairing precision of each time is ensured, the repair rate is zero, the production efficiency is improved by 5-10 times, the labor intensity of operators is reduced, and the labor cost and the production cost are saved; and the tool is simple in structure and convenient to operate, the operation difficulty of post-welding deformation adjustment and repair of the longitudinal beam assembly is reduced, and the production quality is guaranteed.
Description
technical field [0001] The invention relates to the technical field of rail passenger car bogie adjustment and repair, in particular to a rail passenger car bogie longitudinal beam component adjustment and repair tooling. Background technique [0002] Such as figure 1 and figure 2 As shown, the rail passenger car bogie longitudinal beam assembly 5 is composed of an upper cover plate 5-1, a rib plate 5-2, a web 5-3 and a lower cover plate 5-4. During the bogie manufacturing process, the upper cover plate 5 When -1 is welded with the rib plate 5-2, due to the large amount of welding at the junction of the rib plate 5-2 and the upper cover plate 5-1, it often causes serious welding deformation at the edge of the upper cover plate 5-1-1. At present, the post-welding repair method of the longitudinal beam assembly 5 is to use flame repairing and rectification. Since the plate of the longitudinal beam assembly 5 is thick, the flame repairing cannot complete the correction at on...
