[0023] In other words, Figure 3As shown, during the welding operation of the water baffle 200 to be welded, since the support contour line 122 of the rib assembly 104 is aligned with the outer surface contour 202 of the water baffle 200 to be welded, the water baffle 200 to be welded can be directly assembled and positioned quickly. Moreover, after the water baffle 200 to be welded is positioned, the water baffle 200 to be welded can be supported and directly pressed against the rib assembly 104. Therefore, the water baffle welding assembly auxiliary device 100 provided by the present invention can achieve rapid and accurate clamping and positioning of the water baffle welding process.

[0024] Continue to see Figure 1 and Figure 2 In an embodiment of the present invention, in order to realize the assembly and welding of the two Z-shaped edges of the water retaining plate at different heights, the rib assembly 104 can further include a first rib assembly 106 and a second rib assembly 108. Specifically, the height of the first rib assembly 106 can be set to be lower than the height of the second rib assembly 108, and the support contour lines of the multiple ribs of the first rib assembly 106 and the support contour lines of the multiple ribs of the second rib assembly 108 are opposite to each other, thereby realizing the assembly and welding of the Z-shaped edges of different water retaining plates at different heights or shapes. Of course, it should be understood that Figure 1 and Figure 2 What is shown is merely an illustrative embodiment of the present invention and does not constitute any particular limitation to the present invention.

[0025] For the rib assembly 104 of the water retaining plate welding assembly auxiliary device 100, in the embodiment of the present invention, the rib assembly 104 may include a plurality of ribs 110 and a pressing assembly 112. Specifically, Figure 1 and Figure 2 As shown, a plurality of ribs 110 can be arranged at intervals along the length direction L of the main frame assembly 102, and each rib 110 can also be arranged along the width direction W of the main frame assembly 102, and the support contour line 122 as described above can be formed on the inner edge of each rib 110, thereby forming Figure 1 and Figure 2 Furthermore, for the pressing assembly 112, the pressing assembly 112 can be set on the plurality of ribs 110, and the pressing assembly 112 can extend along the length direction L of the main frame assembly 102. During actual application, as shown in FIG. Figure 3 As shown, the pressing assembly 112 can be used to press the water baffle 200 to be welded.

[0026] In an optional embodiment, the clamping assembly 112 may further include a clamping support 114 and a clamping member 116. Specifically, for the clamping support 114, the clamping support 114 may include a top 124 provided on the top contour line 118 of the plurality of ribs 110 and a side 126 provided on the back contour line 120 of the plurality of ribs 110, wherein the back contour line 120 of the ribs 110 is provided opposite to the support contour line 122 as described above. As for the clamping member 116, the clamping member 116 may include a support 128 provided on the side 126 of the clamping support 114 and a clamping bolt 130 connected to the support 128 and capable of being raised and lowered relative to the top 124 of the clamping support 114. Thus, a structure as shown in FIG. Figure 1 and Figure 2 The overall structure of the pressing assembly 112 shown in FIG. Figure 3 As shown, the water baffle 200 to be welded can be effectively positioned and pressed quickly.

[0027] In an optional embodiment, a slide groove 132 may be formed on the side portion 126 of the pressing support member 114. Specifically, the slide groove 132 may extend along the length direction L of the main frame assembly 102, and the support 128 of the pressing member 116 may be movable in the slide groove 132, for example, may slide in the slide groove 132. Thus, the position of the pressing member 116 can be adjusted. Figure 1 and Figure 3 As shown, the number of pressing members 116 can be, for example, multiple, and the support 128 of each pressing member 116 can slide independently in the above-described chute 132. It should be understood that the specific number of pressing members 116 and the manner in which they move in the chute 132 are merely illustrative. In other embodiments of the present invention, a different number of pressing members 116 can be provided, and the pressing members 116 can also move in the chute 132 in other manners. In other words, the above is merely an illustrative embodiment of the present invention and does not constitute any particular limitation on the present invention.

[0028] Return to continue Figure 1 and Figure 2 Combined with Figure 3 In an embodiment of the present invention, a positioning block 134 may be further provided on the main frame assembly 102. Specifically, the positioning block 134 may extend along the length direction L of the main frame assembly 102 and be provided opposite to the support contour line 122 of the plurality of ribs 110. In actual application, the water retaining plate 200 to be welded may be positioned between the support contour line 122 and the positioning block 134, thereby achieving accurate positioning of the water retaining plate 200 to be welded. In an optional embodiment, as Figures 1 to 3As shown, when the rib assembly 104 includes a first rib assembly 106 and a second rib assembly 108 , the positioning blocks 134 can be correspondingly provided as a pair, and are used to match the first rib assembly 106 and the second rib assembly 108 , respectively.

[0029] In an embodiment of the present invention, the main frame assembly 102 may include a lower frame 136 and a table 138. Specifically, the table 138 may be disposed on the lower frame 136, and the rib assembly 104 and positioning block 134 described above may also be disposed on the table 138. In another optional embodiment, since the water shield 200 to be welded is generally long, the water shield welding assembly auxiliary device 100 may further include an extension frame assembly 140 to provide stable support for the water shield 200 to be welded. Specifically, the extension frame assembly 140 may be slidably connected to the main frame assembly 102 and movable along the length direction L of the main frame assembly 102. In one embodiment of the present invention, the extension frame assembly 140 may include an extension frame 142 and an extension table 144. Specifically, the extension table 144 may be disposed on the extension frame 142 and slidably connected to the table 138 of the main frame assembly 102. When the other end of the water retaining plate 200 to be welded needs to be supported, it is only necessary to slide the extension table 144 and the extension frame 142 relative to the table 138 and the lower frame 136 .

[0030] During the actual application of the water baffle welding assembly auxiliary device 100 provided by the embodiment of the present invention, the operator can first place the Z-shaped water baffle 200 to be welded on the table 138. At this time, the edge of one side of the water baffle 200 to be welded is placed tightly between the rib plate 110 and the positioning block 134, and the outer surface profile 202 of the water baffle 200 to be welded is closely aligned with the support profile 122 of the rib plate 110. Conversely, the other edge of the water baffle 200 to be welded is placed on the top 124 of the clamping support member 114 and is clamped using the clamping bolt 130 of the clamping member 116. Then, the extension frame 142 and the extension table 144 are slid out to support the other end of the water baffle 200 to be welded.

[0031] After completing the assembly and pressing, the spiral welding operation method is used to weld the plug welding hole. The specific operation is: start the arc in the middle of the welding hole, spirally swing the welding gun, and during the rotation process, the overlap between the welds is always maintained at 1 / 2. After the welding hole is filled, quickly bring the arc back to the middle of the welding hole, and use the current attenuation method (set the arc ending current to 40% of the welding current) to fill the arc pit and extinguish the arc to complete the welding. The water baffle can be released and pressed only after it has completely cooled to room temperature.

[0032] In summary, the water baffle welding assembly auxiliary device 100 provided in the embodiment of the present invention can be used for welding deformation control, root gap precision control, post-completion dimensional detection of aluminum alloy 1.2mm water baffle profiles, and a 1mm aluminum alloy plate welding operation method. With the help of the water baffle welding assembly auxiliary device 100 provided in the embodiment of the present invention, it is possible to solve the problems of difficulty in assembling and positioning aluminum alloy rail vehicle water baffles, difficulty in controlling the root gap, easy burn-through of thin plates, large welding deformation, low adjustment and repair efficiency, and inconvenient post-completion dimensional detection. Ultimately, it is possible to achieve precision manufacturing of aluminum alloy rail vehicle water baffle assembly and welding, reduce construction difficulty and welding defects, and improve production efficiency and product quality.

[0033] Specifically, the water baffle welding assembly auxiliary device 100 of the present invention can realize the assembly and welding of different heights of the two edges of the Z-shaped water baffle, and cooperate with the movable clamping device to realize the rapid and precise clamping and positioning of the 1.2mm thick aluminum alloy plate. In addition, the water baffle is in the shape of "Z" and has a length of 1980mm. It is easy to be distorted as a whole after welding. Since the thickness of the plate itself is small, it is difficult to adjust. Therefore, in order to control the welding deformation, the device uses a three-dimensional clamping method, that is, the height direction is clamped by the clamping support and the clamping bolt, the length direction is supported by the extended frame assembly, and the width direction is supported by the positioning block and the rib plate. In this process, the chord height of the clamping support is 2mm, and it is clamped with the clamping bolt to offset the concave deformation after welding. Furthermore, the device can simultaneously realize assembly, welding, grinding and cleaning work, and after completion, the size and welding deformation of the water baffle can be directly detected by the device rib plate template, reducing the complicated measurement process. In addition, the "spiral" welding operation method is used during the welding process to prevent burn-through at the edge of the weld, ensure the effective thickness of the weld and reduce the occurrence of welding defects.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
