[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0021] Example

[0022] like Figure 1 , Figure 2 As shown, Figure 1 Shown is an overall schematic diagram of a welding fixture in an embodiment; Figure 2 What is shown is a schematic diagram of the structure of the clamping member in the embodiment;

[0023] The device includes:

[0024] Bottom plate 10;

[0025] Clamping parts, multiple groups of clamping parts are distributed around the edges of the top of the bottom plate 10, each group of clamping parts corresponds to clamping one of the side plates 1 of the battery box, and multiple side plates 1 are spliced ​​together to form the side wall of the battery box;

[0026] The positioning member is arranged at the top of the bottom plate 10 , and the positioning member positions the side plate 1 clamped by the clamping member so that the multiple side plates 1 can be smoothly enclosed.

[0027] By setting up multiple groups of clamping members, all side walls that surround the battery box side wall can be fixed at once, and the side panel 1 can be quickly positioned when clamping through the setting positioning members, so that multiple side panels 1 can be quickly enclosed and the welding efficiency is improved.

[0028] The clamping member includes a fixed plate 21, a movable plate 22 and a fixed plate 24 which are arranged parallel to each other and have a certain interval, wherein the bottom ends of the fixed plate 21 and the fixed plate 24 are fixedly connected to the top of the bottom plate 10, the movable plate 22 is in sliding contact with the bottom plate 10, and a plurality of springs 23 are arranged between the movable plate 22 and the fixed plate 21; the two ends of the spring 23 are fixedly connected to the side walls of the fixed plate 21 and the movable plate 22 respectively.

[0029] The side plate 1 is clamped by inserting it into the gap between the movable plate 22 and the fixed plate 24. After the side plate 1 is inserted into the gap, the spring 23 is in a compressed state. The spring 23 exerts a force on the movable plate 22 toward the fixed plate 24 due to the compression, so that the side plate 1 can be clamped stably.

[0030] The bottom plate 10 is set on the workbench, and the movable plate 22 and the fixed plate 24 are perpendicular to the bottom plate 10. The movable plate 22 and the fixed plate 24 are parallel to each other so that the side plate 1 inserted into the gap between them is also perpendicular to the bottom plate 10, thereby ensuring that the side plate 1 is in a vertical relationship with the bottom surface when clamped, thereby ensuring the accuracy of the fixed position of the side plate 1.

[0031] The positioning member includes a fixing column 31 and a threaded rod 32 horizontally inserted into the fixing column 31, the threaded rod 32 is threadedly connected to the fixing column 31, the positioning member is arranged in parallel on one side of one set of clamping members, the threaded rod 32 is arranged at the end of the side plate 1 clamped by the set of clamping members, the threaded rod 32 is perpendicular to the side plate 1 and contacts the end of the side plate 1;

[0032] When a group of clamping members closest to the positioning member clamps the side panel 1, the threaded rod 32 is rotated to make the end of the threaded rod 32 extend from the fixing column 31, and then the end of the side panel 1 close to the threaded rod 32 is brought close to and contacts the threaded rod 32, and at the same time, the side panel 1 is inserted into the gap between the movable plate 22 and the fixed plate 24. The threaded rod 32 limits the side panel 1, and after the side panel 1 is clamped stably, another group of adjacent side panels 1 close to the clamping members is installed, so that the two adjacent side panels 1 are assembled with each other.

[0033] In this embodiment, two groups of positioning members are provided, which are located at opposite diagonal positions respectively, so as to further ensure the positioning of the side panels 1; and after all the side panels 1 are installed stably, the threaded rod 32 is rotated in the opposite direction so that the threaded rod 32 is retracted, which does not hinder the subsequent welding of the splicing gaps.

[0034] The tops of the movable plate 22 and the second fixed plate 24 are both provided with arc-shaped end surfaces 41 ; the arc-shaped end surfaces 41 are provided so that the side plate 1 plays a guiding role when being inserted into the gap between the movable plate 22 and the second fixed plate 24 , making the insertion smoother.

[0035] like Figure 3 As shown, Figure 3 The diagram shows a plan view of the second fixing plate in the embodiment.

[0036] The plate bodies of the movable plate 22 and the second fixed plate 24 are both provided with a plurality of hollow portions 42 ; the hollow portions 42 can reduce the manufacturing cost of the movable plate 22 and the second fixed plate 24 without affecting the clamping of the side plates 1 .

[0037] Working principle: When using the device to weld the side wall of the battery box, first rotate one of the threaded rods 32 to make the end of the threaded rod 32 extend from the fixing column 31, and then install the side panel 1 closest to the threaded rod 32 first, so that the end of the side panel 1 close to the threaded rod 32 is close to and contacts the threaded rod 32, and at the same time, the side panel 1 is inserted into the gap between the corresponding movable plate 22 and the fixed plate 24, and the threaded rod 32 acts as a limit for the side panel 1. Then, after the side panel 1 is clamped and stabilized, another group of adjacent side panels 1 close to the clamping member are installed in the same way, so that the two adjacent side panels 1 are spliced ​​with each other. Finally, on the basis of the installed side panels 1, other side panels are installed in the same way, and finally all side panels 1 are fixed. After all side panels 1 are installed and stabilized, the threaded rod 32 is rotated in the opposite direction to retract the threaded rod 32, which does not hinder the subsequent welding of the splicing gap.

[0038] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
