Description

Technical Field

[0001] The utility model belongs to the relevant technical field of airtightness detection fixtures, in particular to an airtightness tooling fixture for an energy storage box. Background Art

[0002] Energy storage boxes are generally used to store energy storage components. In order to ensure the sealing of the box body in the later stage, the existing energy storage boxes such as Figure 1 , Figure 2 As shown, the whole includes a left partition 15, a right partition 16, a front panel 17, a bottom plate 18, an upper plate 19, a rear plate 20 and a plurality of rivet nuts 21. The left partition 15 and the right partition 16 are double-layer hollow structures. The left partition 15 and the right partition 16 are spliced ​​left and right to form a frame, and then the upper plate 19 and the bottom plate 18 are fixed on the upper and lower parts of the frame, and the front panel 17 and the rear plate 20 are spliced ​​on the front and back of the frame to finally form an energy storage box with a hollow center. Then, a plurality of rivet nuts 21 are riveted by a riveting process to facilitate the later fixing of the cover plate above the entire energy storage box, and the front panel 17 is provided with a plurality of installation function through grooves to facilitate the later installation of other components. The left partition plate 15, the right partition plate 16, the front panel 17 (relatively thin material), the bottom plate 18, the upper plate 19, and the rear plate 20 in the energy storage box are welded together. Since the various components of the energy storage box are completed by welding, and the energy storage box cannot be filled with water or air after processing, it is necessary to perform an air tightness test on the entire energy storage box after welding. At the same time, in order to facilitate the test, two air intake detection ports 17-1 for communicating with the inside of the frame are provided on the front panel 17.

[0003] At present, there is an airtight fixture for energy storage boxes, such as announcement number CN 117433701 A, which is called an energy storage box cover airtightness inspection fixture. It uses an integral pressing frame to clamp the energy storage box cover, and uses the side anti-deformation plate and the top anti-deformation plate to avoid the deformation of the bottom and sides of the energy storage box cover. However, the structure does not press and prevent the front panel 17 from being deformed. If only the anti-deformation plate is added to the side, during the airtightness detection process, the two sides and the top of the product can only be squeezed forward and backward during the process of being shaped and limited. Considering that multiple through holes are dug above the front panel 17, the overall area is relatively small, the overall strength is softer, and it is easier to deform. The rear panel 20 is not easy to deform due to its strong hardness. Once the front panel 17 is deformed and protrudes outward or is squeezed and concave, the entire product is easily scrapped. Therefore, how to design a fixture for bidirectional positioning of the front panel 17 of the energy storage box to prevent its deformation is particularly important. Utility Model Content
