Description

Technical Field

[0001] The utility model relates to a device for detecting the bending of an energy storage box shell, and belongs to the technical field of energy storage box production. Background Art

[0002] Energy storage refers to the process of storing energy through a medium or device and releasing it when needed. For example, converting renewable energy such as solar energy and wind energy into electrical energy through energy storage technology can provide clean energy stably without being affected by fluctuations in the supply of renewable energy. It helps to solve the imbalance between energy supply and demand, improve energy utilization efficiency and promote the development of renewable energy. Therefore, energy storage technology is of great significance in today's energy field.

[0003] Battery energy storage is one of the main energy storage technologies at present. The main function of the energy storage battery box shell is to protect the energy storage battery unit and other related components from the influence of the external environment. It can also play a role in waterproofing, dustproofing, and shockproofing. In addition, the energy storage battery box shell can also improve the heat dissipation performance of the battery to maintain the stability and safety of the battery pack.

[0004] The energy storage box shell is formed by cutting, stamping, bending, welding and other steps of the profile. When bending the energy storage box shell, the bending size and tolerance of the U-shaped bending part must be strictly controlled to ensure that it can cooperate well with other components. At present, manual measurement and inspection of the bending size of the energy storage box shell is time-consuming and laborious. In addition, due to manual measurement, it is inevitable that the U-shaped bending part will be deformed, resulting in a large inspection error, which affects the subsequent welding processing accuracy of the energy storage box shell, reduces the quality of the finished product, and reduces the production efficiency of the energy storage box shell. Utility Model Content

[0005] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide an energy storage box shell bending size detection device with high accuracy, high efficiency and simple structure.

[0006] The purpose of the utility model is achieved in this way:

[0008] Furthermore, the straight section fixing device includes a straight section backer fixed on the base and a straight section cylinder cooperating with the straight section backer to clamp the straight section of the U-shaped bottom of the bending shell; the movable end of the straight section cylinder pushes the straight section of the bending shell against the straight section backer to complete the fixing action.

[0009] Furthermore, there are two straight section cylinders, whose movable ends are fixedly connected by a push block, and the push block is used to push the straight section of the bent shell close to the straight section backer.

DETAILED DESCRIPTION

[0022] See also Figure 1~Figure 4 The utility model relates to a bending detection device for an energy storage box shell, comprising a base 1, a straight section fixing device, a side arm fixing device and a side arm position feedback device arranged on the base 1, and a measuring device 15; the measuring device 15 is a dial indicator;

[0023] The straight section fixing device is used to fix the U-shaped bottom straight section of the bending shell 10, and includes a straight section backer 6 fixedly mounted on the base 1, and a straight section cylinder 7 that cooperates with the straight section backer 6 to clamp the U-shaped bottom straight section of the bending shell 10; the movable end of the straight section cylinder 7 pushes the straight section of the bending shell 10 against the straight section backer 6 to complete the fixing action; because the straight section is relatively long, in order to further fix the straight section without loosening, two straight section cylinders 7 are provided, and the movable ends of the two straight section cylinders 7 are fixedly connected by a push block 8, and the push block 8 is used to push the straight section of the bending shell 10 against the straight section backer 6, so as to achieve long-distance fixing of the U-shaped bottom straight section of the bending shell 10;

[0024] The side arm fixing device is used to fix the U-shaped side arm at the right end of the bending shell 10, and includes a right backrest 9 fixed on the base 1, and a right cylinder 11 that cooperates with the right backrest 9 to clamp the U-shaped side arm at the right end of the bending shell 10; the movable end of the right cylinder 11 pushes the straight section of the bending shell 10 against the right backrest 9 to complete the fixing action. In this embodiment, in order to prevent the straight section and the right U-shaped side arm of the bending shell 10 from being deformed and affecting the measuring structure when measuring the offset of the U-shaped side arm at the left end of the bending shell 10, the straight section and the right U-shaped side arm must be better fixed and not loosened, and the right cylinder 11 is set on the bisector of the angle between the straight section and the right U-shaped side arm. A right-angle push block 12 with a right-angle contact surface is installed on the movable end of the right cylinder 11. The two right-angle surfaces of the right-angle push block 12 contact the straight section and the right U-shaped side arm of the bending shell 10 respectively, and the straight section and the right U-shaped side arm of the bending shell 10 are pressed and fixed at the same time to ensure that no additional deformation occurs during measurement to affect the measurement accuracy;

[0025] The side arm position feedback device clamps the left U-shaped side arm of the bending shell 10 and ensures that the left U-shaped side arm remains in a freely open state, comprising a slide rail 2 horizontally fixed on the base 1, a support plate 3 freely slidingly arranged on the slide rail 2, a left backrest 4 and a left cylinder 5 fixed on the support plate 3; the movable end of the left cylinder 5 extends to push the left U-shaped side arm against the left backrest 4 to complete the clamping operation; the dial indicator determines the bending size of the bending shell 10 by monitoring the position offset of the left backrest 4; a left limit plate 13 and a right limit plate 14 are provided on the base 1 to limit the left and right movement range of the left backrest 4, and the measuring end of the dial indicator contacts the side of the left backrest 4 to feedback the position offset of the left backrest 4. In this embodiment, the measuring end of the dial indicator contacts the right side surface of the left backrest 4 through the right limit plate 14;

[0026] When detecting the bending size, first place the energy storage box shell that has been bent into a U shape on the straight section fixing device and the side arm fixing device, so that the straight section and the right U-shaped side arm of the bending shell 10 are respectively against the straight section backrest 6 and the right backrest 9, and the left U-shaped side arm is located between the left backrest 4 and the left cylinder 5; start the right cylinder 11 and the straight section cylinder 7 respectively, and push the straight section and the right U-shaped side arm of the bending shell 10 to the straight section backrest 6 and the right backrest 9 to fix them in position; start the left cylinder 5, and push the left U-shaped side arm of the bending shell 10 to the left backrest 4. Since the left backrest 4 and the left cylinder 5 are freely sliding on the slide rail 2, no additional deformation force will be generated on the left U-shaped side arm, ensuring that the left U-shaped side arm is in a free state. At the same time, the dial indicator shows the displacement of the left backrest 4, which reflects the actual bending size of the energy storage box shell.

[0027] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
