[0059] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0060] See also Figure 1-Figure 3 , this application provides the following technical solutions:
[0061] A rail vehicle side wall assembly welding tool comprises a main base 1 fixedly connected to the bottom surface where the tool is located; a first component and a second component are respectively arranged on the main base 1. The first component is located at both ends of the component to be welded, and is used to support and position the ends of the component to be welded; the second component is provided in a plurality of groups and is located between the first components at both ends; the second component is arranged corresponding to the side wall window, and is used to support and position the side wall window component to be welded. A plurality of middle supports 6 are also arranged between adjacent second components and between the first component and the second component. The middle support 6 is a retractable rod structure, and two middle supports 6 are respectively arranged at each position where a middle support 6 is provided. Figure 3 As shown, the middle support member includes an intermediate rod, and the two ends of the intermediate rod are respectively threadedly connected to an end rod, and the overall length thereof can be adjusted by screwing the end rod. A secondary base 5 is provided corresponding to each first component and second component, and the bottom of the secondary base 5 is detachably connected to the main base 1, and the upper part is connected to the first component or the second component; the two ends of the middle support member 6 are respectively connected to the secondary bases 5 on both sides.
[0062] See also Figure 2 The first component is set at both ends of the components to be welded in the current group, and the second component is set on both sides of each side window position. Because the window opening position of the vehicle side wall may be deformed by many factors during welding, the second components are set on both sides of the side window for positioning, which can effectively improve the quality of the welded product.
[0063] On the basis of the above implementation scheme, the main base 1 is a rectangular frame structure; it includes two main rods arranged along its own length direction, and the two main rods are arranged in parallel. The auxiliary base 5 includes a column 51 and a crossbeam 52, and two columns 51 are provided, each connected to a main rod; the crossbeam 52 is arranged above the two columns 51; the two ends of the middle support member 6 are respectively connected to the crossbeams 52 of the two adjacent auxiliary bases 5.
[0064] On the basis of the above embodiment, the auxiliary base 5 further includes a base middle piece 53, which is arranged between the upper end of the column 51 and the lower side of the crossbeam 52. Each base middle piece 53 includes a sliding piece assembly and a fixing piece assembly, such as Figure 4 and Figure 5 As shown, the sliding member assembly includes a slide rail and a slider arranged between the column 51 and the beam 52, and the column 51 and the beam 52 can be slidably connected through the sliding member assembly; the fixing member assembly is arranged on one side of the sliding member assembly, and the column 51 and the beam 52 can be fixedly connected through the fixing member assembly.
[0065] Because when performing welding operations, the workpiece needs to be fixed first, and the side wall-related workpieces are relatively large. In order to facilitate the position adjustment of the auxiliary base 5, the connecting bolts between the lower part of the column 51 and the main base 1 can be loosened first, and then the bolts of the fixing assembly can be removed. At this time, the crossbeam 52 and the column 51 are still in a connected state and can slide. This state is convenient for lateral movement of the position of the auxiliary base 5, and while maintaining the connected state, it will not cause the workpiece to be welded to fall. After the position adjustment is completed, the auxiliary base 5 is restored to a fixed state, and subsequent operations can be carried out. This connection method can make a certain degree of adjustment while maintaining the support state of the workpiece without removing the workpiece.
[0066] On the basis of the above implementation scheme, the first component and the second component both include a fixed component 2, a movable component 3 and an intermediate component 4. The fixed component 2 is arranged at one end of the corresponding crossbeam 52 and is fixedly connected to the crossbeam 52; the movable component 3 is arranged at the other end of the corresponding crossbeam 52 and is slidably connected to the crossbeam 52, and can move toward or away from the fixed component 2 along the length direction of the crossbeam 52; the intermediate component 4 is arranged between the fixed component 2 and the movable component 3, and the lower part of the intermediate component 4 is connected to the crossbeam 52; the intermediate component 4 is used to support and position the middle part of the workpiece to be welded.
[0067] Through the combination of the three parts, adaptive adjustment for different types of side walls is achieved. The difference between the first component and the second component is that a limit piece is also provided on the side of the first component facing the outside of the main base 1, which is used to abut against the outer end of the side wall workpiece, ensuring the overall length limit of this set of welding components.
[0068] On the basis of the above implementation scheme, the fixed component 2 includes a fixed vertical pole 21, a fixed horizontal arm 22 and a fixed pressing component 23. The fixed vertical pole 21 is fixedly connected to the upper side of the beam 53; the fixed vertical pole 21 is a vertically arranged rod body; the fixed horizontal arm 22 is sleeved with the fixed vertical pole 21 and slidably connected in the vertical direction, and the fixed horizontal arm 22 extends toward the horizontal side; the fixed pressing component 23 is connected to one end of the fixed horizontal arm 22 away from the fixed vertical pole 21, and can slide in the vertical direction, and the fixed pressing component 23 can apply downward pressure toward the workpiece to be welded.
[0069] The upper end of the fixed pole 21 is an arc-shaped surface, and its arc-shaped structure corresponds to the curved structure below the window of the side wall. The fixed pressing component 23 can apply downward pressure toward the top position of the fixed pole 21 or the middle component 4.

Figure 5 On the contrary, the upper side of the window is set towards the direction of the fixing component 2. Because the two are placed in different directions, the overall bending direction is also different. For the two states, the fixing component 2 is matched with the fixed ratio 22 and the fixed compression component 23 extending in different directions. Figure 4 The fixed pressing component 23 applies force in the direction toward the end of the intermediate component 4 . Figure 5 The fixed pressing component 23 applies force toward the arc-shaped structure at the upper end of the fixed upright rod 21 .
[0071] On the basis of the above implementation scheme, the movable assembly 3 includes a movable upright rod 31, a movable support 32 and a movable driving member 33. The movable upright rod 31 is detachably connected to the cross beam 52, the upper part of the movable upright rod 31 extends toward the middle assembly 4, and a pressing member capable of exerting downward force is arranged above the movable upright rod 31; the movable support 32 is arranged on the side of the movable upright rod 31 facing the middle assembly 4, and the movable support 32 is slidably connected to the cross beam 52; a positioning groove corresponding to the workpiece to be welded is provided on the upper side of the movable support 32; the movable driving member 33 is a retractable cylinder, one end of which is connected to the movable support 32, and the other end is connected to the middle assembly 4.

[0073] On the basis of the above implementation scheme, the intermediate component 4 includes an intermediate pole 41, an intermediate support 42 and a middle positioning member group. Two intermediate poles 41 are provided, which are respectively provided near the fixed component 2 and the movable component 3; the intermediate support 42 is provided across the upper part of the two intermediate poles 41 and is fixedly connected to the intermediate poles 41; the middle positioning member group is provided on the intermediate support 42, and includes a plurality of positioning members that can be positioned on the upper side or the lower side of the workpiece to be welded.
[0074] The intermediate positioning member group includes an upper positioning member 43, a lower positioning member 44, an end positioning member 45 and a side positioning member. The lower portion of the upper positioning member 43 is rotatably connected to the intermediate support 42, and the upper portion is provided with a pressure member that can apply downward force; the upper positioning member 43 can be a combination of a bolt and a limit block structure, and the distance and applied force between the limit block and the workpiece to be welded can be adjusted by the bolt. The lower positioning member 44 includes a positioning seat and a positioning cylinder. The positioning seat is a connecting plate structure, which is rotatably connected to the intermediate support 42; the positioning cylinder is a cylinder, and its cylinder body shell is fixedly connected to the positioning seat, and the cylinder body can move toward or away from the lower side of the assembly to be welded.

When necessary, side positioning members can be set on both sides of the intermediate support 42, and the workpiece can be positioned laterally in combination with the cylinder and the clamping block. The lateral direction here refers to both sides of the length direction of the intermediate support 42. In other words, the side positioning members are distributed on both sides of the intermediate support 42 along the length direction of the main base 1.
