Description

Technical Field

[0001] This utility model specifically relates to a welding fixture for an explosion-proof valve with a double-through long aluminum shell. Background Technology

[0002] As a type of battery, power batteries are widely used in people's daily lives. They provide power for tools and are rechargeable batteries that power electric vehicles, electric trains, electric bicycles, and golf carts. Power batteries are a core component of new energy vehicles and an important direction for future energy transformation. The components of a power battery casing generally include the casing itself and an explosion-proof valve installed on the casing. The explosion-proof valve is designed to prevent the battery from spontaneously exploding.

[0003] When welding existing explosion-proof valves and double-through aluminum shells, it is often necessary to position the double-through aluminum shell first, then place the explosion-proof valve on the long aluminum shell for positioning, and finally weld the two together. However, the existing tooling fixtures are often relatively simple, and due to the different models of double-through aluminum shells, the slots for installing the explosion-proof valve and the explosion-proof valves themselves are different. When welding different double-through aluminum shells, workers need to constantly adjust the positions of the double-through aluminum shell and the explosion-proof valve, which causes great inconvenience to production. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-4 This invention provides a technical solution: a welding fixture for an explosion-proof valve with a double-through long aluminum shell, comprising:

[0031] Base 1;

[0032] Side plate 2; Side plate 2 and base 1 are detachably connected;

[0033] Positioning plate 4; Positioning plate 4 is connected to side plate 2. Multiple mounting slots 41 are provided on positioning plate 4. Positioning cores 6 for fixing different aluminum shells 3 are respectively provided in mounting slots 41.

[0034] Air pipe connector 5 is set on positioning plate 4. One end of air pipe connector 5 is connected to the drive end of air pump, and the other end is the adsorption end of negative pressure adsorption explosion-proof valve.

[0035] This application first uses a suitable positioning core 6 to fix the double-through aluminum shell to be processed, then uses an air pump to generate negative pressure to adsorb the explosion-proof valve to be welded, and then welds the two together.

[0036] In this embodiment, the positioning core 6 has a third vent hole 63, and the adsorption end is connected to the third vent hole 63. Since the adsorption end is connected to the third vent hole 63, the negative pressure generated by the air pump will also adsorb the explosion-proof valve onto the positioning core 6, and the positioning core 6 will also fix the double-through aluminum shell to be processed, thereby facilitating the alignment of the explosion-proof valve and the double-through aluminum shell before welding.

[0037] In this embodiment, a second vent 43 is provided on the mounting groove 41, and the second vent 43 is correspondingly provided with the third vent 63. The air pipe connector 5 is provided at the bottom end of the positioning plate 4, and it is threadedly connected to the positioning plate 4. The bottom end of the positioning plate 4 is provided with multiple connection points that are threadedly connected to the positioning plate 4. The connection points are generally located below the mounting groove 41. When the welded double-length aluminum shells are different, the appropriate connection point at the bottom end of the positioning plate 4 can be selected as needed to connect with the air pipe connector 5, so as to facilitate the corresponding connection between the adsorption end, the second vent 43, and the third vent 63.

[0038] In this embodiment, a first vent hole 22 is provided on the side plate 2, and an air pipe is connected to the drive end. The other end of the air pipe passes through the first vent hole 22 and is connected to the air pump. The air pipe is used to transport gas and generate negative pressure.

[0039] In this embodiment, the positioning core 6 is provided with a protruding rib 62, and the aluminum shell 3 is provided with a placement groove 32. The bottom end of the placement groove 32 is provided with a positioning hole 31. The placement groove 32 is used to place the explosion-proof valve. The protruding rib 62 and the positioning hole 31 are engaged and locked together. The protruding rib 62 is provided to facilitate the fixing of the aluminum shell 3. The placement groove 32 is used to place the explosion-proof valve, and the negative pressure generated by the adsorption end is used to adsorb the explosion-proof valve, thereby facilitating the welding of the two.

[0040] In this embodiment, a guide slope 64 is provided on the protruding ridge 62, which facilitates the snap-fit ​​alignment of the aluminum shell 3.

[0041] In this embodiment, the positioning core 6 is provided with limiting holes 61 with bolts at both ends, and the mounting groove 41 is also provided with a third mounting hole 42. The third mounting hole 42 is locked to the end of the bolt. The protrusions 62 of different positioning cores 6 are also different to adapt to the fixing of different models of aluminum shells 3. The bolt connection also makes it easy to select and replace the positioning core 6 as needed.

[0042] In this embodiment, the base 1 is provided with a plurality of first mounting holes 11, and the side plate 2 is connected to the first mounting holes 11 by bolts, which facilitates the assembly and disassembly of the base 1 and the side plate 2.

[0043] In this embodiment, a second mounting hole 21 is provided on the side plate 2, and a fourth mounting hole 44 is provided on the positioning plate 4. The fourth mounting hole 44 corresponds to the second mounting hole 21. The fourth mounting hole 44 is connected to the second mounting hole 21 by bolts, which facilitates the assembly and disassembly of the side plate 2 and the positioning plate 4.

[0044] The working principle and usage process of this invention are as follows: When using the invention, first select a suitable positioning core 6 and place it in a suitable mounting groove 41 for fixation. Since the height of the aluminum shell 3 to be processed is higher than the combined height of the positioning plate 4 and the air pipe connector 5, lift the aluminum shell 3 to be processed so that its bottom surface is lower than the position of the air pipe connector 5. Then, slowly move the aluminum shell 3 horizontally so that it fits onto the positioning plate 4. Then, slowly lower the aluminum shell 3 vertically so that the positioning hole 31 and the protrusion 62 engage. Place the explosion-proof valve to be welded in the placement groove 32, then start the air pump to generate negative pressure to adsorb and fix the explosion-proof valve. Then, perform the welding operation. When the welding is completed, turn off the air pump, lift the aluminum shell 3 so that the positioning hole 31 is disengaged from the protrusion 62, and then move it horizontally to remove the aluminum shell 3.

[0045] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
