[0001] The utility model relates to the technical field of batteries, and in particular to a welding positioning tool and a positioning device for a partition plate in a double-row module. Background Art

[0002] As the energy density requirements for battery packs become higher and higher, the existing double-row battery modules have a growing production capacity due to their high energy and small footprint. Double-row and multi-row battery modules require a middle partition between two adjacent rows of batteries to improve the overall structural rigidity, so the strength requirements for the middle partition are relatively high.

[0003] In the prior art, the webs of two T-shaped plates are usually welded to the two ends of a straight plate to form an H-shaped middle partition, and the webs of the two T-shaped plates are respectively welded to the front and back side walls of the straight plate, so that when the middle partition and the battery module are installed, the installers can place them at will without affecting the consistency between all the middle partitions.

[0004] However, during the welding process, if the relative position between the T-plate and the straight plate is unstable or the butt joint is not aligned, it is easy to cause the welding strength of the T-plate to fail to meet the requirements, or fail to meet the profile requirements after welding.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] The following is a further detailed description of an embodiment of a double-row module intermediate partition welding positioning tool and a positioning device of the utility model in conjunction with the accompanying drawings.

[0033] like Figure 1As shown, the middle partition of the double-row module that needs to be welded and formed in this application. The middle partition includes a middle straight plate 32 and two T-shaped plates 31 welded at both ends of the middle straight plate 32 in the length direction. The T-shaped plate 31 includes a flange plate and a web plate that are perpendicular to each other, and the web plate is vertically connected to the middle of the flange plate. When the two T-shaped plates 31 are welded with the middle straight plate 32, it is necessary to align the web plates of the two T-shaped plates 31 with the middle straight plate 32, and the middle straight plate 32 is flat on the web plate of the T-shaped plate 31, and then the two ends of the middle straight plate 32 are welded together with the web plate of the T-shaped plate 31 by penetration welding, and the web plates of the two T-shaped plates 31 at both ends are respectively welded to the front and back side walls of the middle straight plate 32.

[0034] It can be seen that the central straight plate 32 should be aligned with the two T-shaped plates 31 before welding, and the relative position between the T-shaped plates 31 and the central straight plate 32 should be fixed during welding to ensure the welding quality.

[0035] Therefore, on the one hand, Figures 2 to 4 As shown, the present application provides a double-row module partition welding positioning tool, including a placement table 1, on which a limited position accommodating space 12 and a positioning accommodating space 11 are provided, the positioning accommodating space 11 is used to place a T-shaped plate 31, and the web of the T-shaped plate 31 is flush with the top surface of the placement table 1 to form a flat table surface for placing a middle straight plate 32, the limited position accommodating space 12 is used to place another T-shaped plate 31, and the web of the T-shaped plate 31 can be pressed and placed on the middle straight plate 32 on the above-mentioned flat table surface.

[0036] It can be understood that before welding, a T-shaped plate 31 is first placed in the positioning and accommodating space 11. After the T-shaped plate 31 is placed in the positioning and accommodating space 11, the web of the T-shaped plate 31 is flush with the top surface of the placing table 1, and then the middle straight plate 32 is placed on the flat table formed by the placing table 1 and the web of the T-shaped plate 31, so that the end of the middle straight plate 32 can be placed in contact with the web of the T-shaped plate 31, and another T-shaped plate 31 is placed in the limiting accommodating space 12, so that the web of the T-shaped plate 31 is pressed against the middle straight plate 32 to prevent the middle straight plate 32 from shifting. After determining the relative position of the T-shaped plate 31 and the middle straight plate 32 in the positioning and accommodating space 11, the middle straight plate 32 and the T-shaped plate 31 can be penetrated and welded at the overlapping position of the webs. After welding is completed, the T-shaped plate 31 welded to one end of the middle straight plate 32 is taken out from the positioning and accommodating space 11, and the other T-shaped plate 31 is placed in the positioning and accommodating space 11, and the middle straight plate 32 is turned over so that the middle straight plate 32 is placed on the flat table surface formed by the placing table 1 and the web of the T-shaped plate 31, and the other end of the middle straight plate 32 is placed on the web of the T-shaped plate 31, that is, the other end of the middle straight plate 32 and the web of the T-shaped plate 31 can be penetrated and welded to complete the welding of the two T-shaped plates 31 and the middle straight plate 32.

[0037] Therefore, the T-shaped plate 31 can be positioned by the positioning accommodation space 11, and the relative position of the central straight plate 32 can be determined by the positioned T-shaped plate 31, so that the central straight plate 32 and the T-shaped plate 31 can be kept in a completely fitted state, which is convenient for welding. The central straight plate 32 can be pressed by another T-shaped plate 31 through the limiting accommodation space 12 to prevent the central straight plate 32 from shifting.

[0038] In some optional embodiments, the positioning and accommodating space 11 includes a positioning hole 111 and an accommodating groove 112 . The positioning hole 111 is used to plug in the flange plate of the T-shaped plate 31 . The accommodating groove 112 is connected to the positioning hole 111 and is used to place the web of the T-shaped plate 31 .

[0039] That is to say, the positioning hole 111 and the receiving groove 112 form a stepped positioning and receiving space 11, and the depth of the positioning hole 111 is not limited. In this example, the positioning hole 111 is a through hole that completely penetrates the placement platform 1 to accommodate flange plates of different lengths; the depth of the receiving groove 112 is adapted to the thickness of the web, so that when the web of the T-shaped plate 31 is placed in the receiving groove 112, the web is flush with the top surface of the placement platform 1.

[0040] In some optional embodiments, the limiting accommodating space 12 and the positioning accommodating space 11 are spaced apart so that the flange plates of the two T-shaped plates 31 placed in the limiting accommodating space 12 and the positioning accommodating space 11 are clamped at both ends of the first direction of the middle straight plate 32 .

[0041] It can be understood that when the limiting accommodation space 12 and the positioning accommodation space 11 are arranged at intervals at the two ends of the placement platform 1 for placing the middle straight plate 32, the web of the other T-shaped plate 31 located in the limiting accommodation space 12 can not only press the middle straight plate 32, but also cooperate with the flange plate of the T-shaped plate 31 located in the positioning accommodation space 11, so that the middle straight plate 32 is clamped between the flange plates of the two T-shaped plates 31, thereby limiting the relative position of the middle straight plate 32 in its first direction. In this example, the first direction is Figure 2 The A direction is the length direction of the middle straight plate 32.

[0042] Furthermore, the above-mentioned limiting accommodating space 12 is a through hole adapted to the size of the flange plate of the above-mentioned T-shaped plate 31, and the width of the above-mentioned limiting accommodating space 12 along the first direction of the above-mentioned straight plate 32 is greater than the width of the flange plate of the above-mentioned T-shaped plate 31 along the first direction of the above-mentioned straight plate 32.

[0043] It can be understood that the width of the position limiting accommodation space 12 is greater than the width of the web of the T-shaped plate 31, so that the flange of the T-shaped plate 31 can move in the through hole along the first direction. The purpose of this arrangement is to adapt to different lengths of the middle straight plate 32, and after the end of the middle straight plate 32 is placed in contact with the web of the T-shaped plate 31 located in the positioning accommodation space 11, another T-shaped plate 31 is placed in the position limiting accommodation space 12, so that the web of the T-shaped plate 31 is pressed against the middle straight plate 32, and then the T-shaped plate 31 is pushed to move along the length direction of the middle straight plate 32 toward the direction of the other T-shaped plate 31, so that the two ends of the middle straight plate 32 are respectively pressed against the flanges of the two T-shaped plates 31.

[0044] In some optional embodiments, on the placement table 1 , a supporting block 2 is provided on the side away from the limiting accommodating space 12 and the positioning accommodating space 11 , for supporting the flange plate of the T-shaped plate 31 .

[0045] Optionally, the supporting block 2 is connected to the placing table 1 by bolts.

[0046] In some optional embodiments, the supporting block 2 located at one side of the position limiting accommodation space 12 can move along the first direction of the middle straight plate 32 .

[0047] Specifically, a long straight hole 21 is provided on the support block 2 located on one side of the limiting accommodation space 12 and is opened toward the positioning accommodation space 11. The positioning bolt passes through the placement platform 1 and the long straight hole 21 and cooperates with the positioning nut to clamp and fix the relative position of the support block 2 on the placement platform 1. When the support block 2 needs to be moved, the positioning nut is loosened to move the support block 2 relative to the positioning bolt until it is held against the flange plate of the T-shaped plate 31, and the positioning nut is tightened to fix the support block 2.

[0048] That is to say, the flange plate of the T-shaped plate 31 in the limiting accommodating space 12 can move in the through hole along the length direction of the middle straight plate 32 to adapt to the middle straight plate 32 of different lengths, and can cooperate with the T-shaped plate 31 located in the positioning accommodating space 11 to clamp the middle straight plate 32, and the supporting block 2 provides a supporting force for clamping the T-shaped plate 31.

[0049] In some optional embodiments, a limit block 5 is respectively provided on both sides of the above-mentioned limiting accommodating space 12 and the above-mentioned positioning accommodating space 11 on the above-mentioned placing table 1, for limiting the relative position of the above-mentioned straight plate 32 in the second direction.

[0050] It can be understood that two limiting blocks 5 and a top abutting block 2 enclose a limiting space for restricting the displacement of the middle straight plate 32. In this example, the two limiting blocks 5 are both perpendicular to the top abutting block 2 and are located on both sides of the top abutting block 2, forming a "C"-shaped limiting space. The spacing distance between the two limiting blocks 5 is adapted to the width of the middle straight plate 32. In this example, the second direction is Figure 2 the B direction in

[0051] , which is the width direction of the middle straight plate 32.

[0052] In some alternative embodiments, the partition welding positioning tooling for the double-row module further includes a pressing component 4 for pressing the web of the T-shaped plate 31 located in the above-mentioned limiting accommodation space 12.

[0053] To further prevent the middle straight plate 32 from shifting, the pressing component 4 is provided. During use, the web of the T-shaped plate 31 located in the limiting accommodation space 12 is pressed against the middle straight plate 32, and the pressing component 4 presses on the web of the T-shaped plate 31, thereby fixing the relative position of the middle straight plate 32 relative to the T-shaped plate 31.

[0054] In this example, the pedestal 41 is arranged on the top abutting block 2 close to the limiting accommodation space 12. The pressing member 42 is also provided with a telescopic elastic buffer member, so that when the clamping member 43 abuts against the pressing member 42 and presses down to press the web of the T-shaped plate 31 located in the above-mentioned limiting accommodation space 12, the elastic buffer member is first compressed, thereby preventing the T-shaped plate 31 and the middle straight plate 32 from being damaged by pressing.

[0055] On the other hand, as Figure 2 shown, the present application also provides a partition welding positioning device for a double-row module, including a line body tray 6 and any one of the above-mentioned positioning toolings.

[0056] Specifically, the placement table 1 is connected to the above-mentioned line body tray 6, and two sets of limiting accommodation spaces 12 and positioning accommodation spaces 11 are arranged side by side on the placement table 1.

[0057] That is to say, two middle partitions can be welded simultaneously on the placement table 1, thereby improving the welding efficiency.

[0058] Of course, the number of middle partitions that can be welded simultaneously on the placement table 1 is set according to actual processing requirements.

[0059] The working principle of the embodiment of the present application is as follows: before welding, a T-shaped plate 31 is first placed in the positioning and accommodating space 11. After the T-shaped plate 31 is placed in the positioning and accommodating space 11, the web of the T-shaped plate 31 is flush with the top surface of the placement table 1, and then the middle straight plate 32 is placed on the flat table surface formed by the placement table 1 and the web of the T-shaped plate 31, and the middle straight plate 32 is located between the two limit blocks 5, so that the end of the middle straight plate 32 can be placed in contact with the web of the T-shaped plate 31 and the position is determined, and the other A T-shaped plate 31 is placed in the limiting accommodating space 12, so that the web of the T-shaped plate 31 is pressed against the middle straight plate 32, and the supporting block 2 located on one side of the limiting accommodating space 12 is pushed until the flange plates of the two T-shaped plates 31 are supported by the two ends of the middle straight plate 32, and the positioning nut is tightened to fix the supporting block 2, and the holding assembly 4 is pressed against the web of the T-shaped plate 31. After the relative position of the middle straight plate 32 and the T-shaped plate 31 is fixed, the middle straight plate 32 and the T-shaped plate 31 can be penetrated and welded at the overlapping part of the web. After welding at one end is completed, the welded T-plate 31 is taken out from the positioning and accommodating space 11, and the other T-plate 31 is placed in the positioning and accommodating space 11, and the middle straight plate 32 is turned over so that the middle straight plate 32 is placed on the flat table surface formed by the placing table 1 and the web of the T-plate 31, and the other end of the middle straight plate 32 is placed on the web of the T-plate 31, and the welded T-plate 31 is placed in the limiting accommodating space 12, and the above operation is repeated, and the other end of the T-plate 31 can be welded to the other end of the middle straight plate 32, and finally a middle partition is formed by welding.

[0060] The utility model discloses a double-row module middle partition welding positioning tool and positioning device. By setting a positioning accommodation space 11, the T-shaped plate 31 can be positioned, and the relative position of the middle straight plate 32 is determined by the positioned T-shaped plate 31, so that the middle straight plate 32 and the T-shaped plate 31 are kept in a completely fitted state. By using the limiting accommodation space 12, the middle straight plate 32 can be pressed by another T-shaped plate 31 to prevent the middle straight plate 32 from shifting, which is convenient for welding. By setting the limiting accommodation space 12 and the positioning accommodation space 11 at intervals, the other T-shaped plate 31 located in the limiting accommodation space 12 can not only press the middle straight plate 32, but also can be with the T-shaped plate 31 located in the positioning accommodation space 11. 1 cooperate with each other to clamp the middle straight plate 32, thereby limiting the relative position of the middle straight plate 32 in its length direction; by making the width of the limiting accommodation space 12 larger than the width of the web of the T-shaped plate 31, the flange plate of the T-shaped plate 31 can move in the through hole along the length direction of the middle straight plate 32 to adapt to the middle straight plate 32 of different lengths; a supporting block 2 is provided, and the supporting block 2 can move along the length direction of the above-mentioned middle straight plate 32 to provide a supporting force for the clamping of the T-shaped plate 31; a limiting space for limiting the displacement of the middle straight plate 32 is formed by two limiting blocks 5 and one supporting block 2, so as to further realize the precise positioning of the T-shaped plate 31 and the middle straight plate 32; a pressing component 4 is provided to further prevent the displacement of the middle straight plate 32.
