Description

Technical Field

[0001] The utility model belongs to the technical field of battery top cover processing, and particularly relates to an adjustable shaping device for a battery top cover. Background Technique

[0002] At present, during the production process of power batteries, laser welding needs to be performed on the top cover sheets of power batteries. Due to many factors such as uneven distribution of welding temperature and shrinkage of deposited metal, deformation will inevitably occur during welding, and the deformation situation is also different at different ambient temperatures. Therefore, a shaping device needs to be used to shape the deformed battery top cover to ensure that it meets the production standards. However, the existing shaping devices for battery top covers are difficult to adjust the shaping parts according to the size of the battery top cover, resulting in the fixed-shaped shaping parts being unable to adapt to different battery top covers for corresponding shaping processes. At the same time, the existing shaping devices for battery top covers are difficult to position the battery top cover, resulting in the battery top cover being prone to offset during shaping, thus affecting its shaping effect. Therefore, an adjustable shaping device for a battery top cover is needed to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide an adjustable shaping device for a battery top cover to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: An adjustable shaping device for a battery top cover, including a platform, a connecting support is fixedly connected above the platform, a first electric push rod is fixedly connected inside the connecting support, a connecting plate is fixedly connected to the bottom end of the first electric push rod, and second electric push rods are fixedly connected to the four corners of the connecting plate, and shaping blocks are fixedly connected to the other ends of the four second electric push rods.

[0005] Two extrusion blocks are fixedly connected to the outside of the first electric push rod, two positioning blocks are arranged inside the platform, two connecting shells are fixedly connected to the bottom of the platform, and third electric push rods are fixedly connected inside the two connecting shells, and top blocks are fixedly connected to the top ends of the two third electric push rods.

[0006] As a preferred implementation manner, two sliding grooves are opened above the platform, and the two positioning blocks are respectively located inside the two sliding grooves.

[0007] As a preferred implementation manner, a spring is fixedly connected to one side of the positioning block, and the other ends of the two springs are respectively fixedly connected to one side of the inner sides of the two sliding grooves.

[0008] As a preferred implementation manner, two through holes are opened above the platform, and the two third electric push rods are respectively located inside the two through holes.

[0009] As a preferred embodiment, four fixing blocks are fixedly connected above the platform, and the same placing block is fixedly connected above the four fixing blocks.

[0010] As a preferred embodiment, support legs are fixedly connected to the four corners of the bottom of the platform, and one side of each of the two pressing blocks and the positioning block is bevel-shaped.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, by providing the second electric push rod, the shaping block, the first electric push rod, the pressing block and the positioning block, the four second electric push rods can respectively drive the shaping block to move, so that the four shaping blocks can adjust the shaping area according to the size of the battery top cover. At the same time, when the first electric push rod drives the four shaping blocks to move downward, it can drive the two pressing blocks to move downward synchronously. When the inclined surfaces of the two positioning blocks are cooperatively pressed by the inclined surfaces of the two pressing blocks, the work of approaching each other can be realized to achieve the purpose of positioning the battery top cover. Furthermore, this device can adjust the distance between the four shaping blocks according to the size of the battery top cover, improving the shaping compatibility between this device and different battery top covers. At the same time, this device can position the battery top cover, avoiding the deviation of the battery top cover during shaping, which may affect its shaping effect.

[0013] In the present utility model, by providing the third electric push rod and the top block, when the four shaping blocks perform the shaping work of pressing down the four corners of the battery top cover, the two third electric push rods can be used to drive the top block to move upward respectively, so that the two top blocks move below the battery top cover to provide a certain upward force on both sides below the battery top cover, preventing the four shaping blocks from excessively pressing the battery top cover and causing deformation of the other side of the battery top cover.

[0020] The following further describes the present utility model in conjunction with embodiments.

[0021] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the protection scope of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement of the method of the present utility model under the premise of the concept of the present utility model belongs to the scope protected by the present utility model.

[0022] Please refer to Figures 1-5 , the present utility model provides an adjustable shaping device for a battery top cover, including a platform 1. Two slide grooves 12 are opened above the platform 1. Two positioning blocks 8 are respectively located in the two slide grooves 12. The slide grooves 12 enable the positioning blocks 8 to have a space for movement, so that when the positioning blocks 8 are extruded by the extrusion blocks 7 and move, they have good stability, preventing the positioning blocks 8 from shifting when moving;

[0023] Two through holes 14 are opened above the platform 1. Two third electric push rods 10 are respectively located in the two through holes 14. The through holes 14 enable the third electric push rods 10 to have a storage space, so that the third electric push rods 10 can drive the top blocks 11 to move upward smoothly, preventing the third electric push rods 10 from being blocked by the platform 1 and unable to move normally;

[0024] Four fixed blocks 15 are fixedly connected above the platform 1. The same placing block 16 is fixedly connected above the four fixed blocks 15. The placing block 16 enables the battery top cover to have a placement point, so that it is convenient for the positioning blocks 8 to position it, and at the same time, the four shaping blocks 6 are convenient for the shaping process;

[0025] Support legs 17 are fixedly connected to the four corners of the bottom of the platform 1. One side of each of the two extrusion blocks 7 and the positioning blocks 8 is bevel-shaped. The support legs 17 enable the platform 1 to have good stability by using a friction layer, preventing the platform 1 from vibrating greatly when the device is in use;

[0026] A connecting support 2 is fixedly connected above the platform 1. A first electric push rod 3 is fixedly connected inside the connecting support 2. The bottom end of the first electric push rod 3 is fixedly connected with a connecting plate 4. The first electric push rod 3 can drive the four shaping blocks 6 to move downward to an appropriate position to perform shaping work on the battery top cover;

[0027] At the four corners of the connecting plate 4, second electric push rods 5 are fixedly connected. The other ends of the four second electric push rods 5 are fixedly connected with shaping blocks 6. The second electric push rods 5 enable the shaping blocks 6 to have the condition of moving, so that the four shaping blocks 6 can adjust the distance between each other according to the size of the battery top cover, so as to achieve the purpose of adapting to battery top covers of different sizes;

[0028] Two extrusion blocks 7 are fixedly connected to the outside of the first electric push rod 3. Two positioning blocks 8 are arranged in the platform 1. When the two extrusion blocks 7 move downward to the two positioning blocks 8, the two extrusion blocks 7 and the two positioning blocks 8 can achieve the fitting extrusion by using the inclined plane positions, so that when the two positioning blocks 8 are extruded by the two extrusion blocks 7, they can move away from each other to achieve the purpose of positioning the battery top cover;

[0029] One side of the positioning block 8 is fixedly connected with a spring 13. The other ends of the two springs 13 are respectively fixedly connected with one side of the inner sides of the two sliding grooves 12. The spring 13 enables the positioning block 8 to have an elastic adjusting force, so that when the positioning block 8 loses the extrusion of the extrusion block 7, the positioning block 8 can be reset;

[0030] Two connecting shells 9 are fixedly connected to the lower part of the platform 1. Third electric push rods 10 are fixedly connected in the two connecting shells 9. The top ends of the two third electric push rods 10 are fixedly connected with top blocks 11. When the two third electric push rods 10 drive the top blocks 11 to move upward to both sides below the battery top cover respectively, the two top blocks 11 can squeeze the battery top cover upward to a certain extent, preventing the battery top cover from being deformed due to excessive extrusion by the four shaping blocks 6. At the same time, cooperating with the pressing of the four shaping blocks 6 can more effectively shape the battery top cover.

[0031] The working principle and usage process of the present utility model:

[0032] When the battery top cover needs to be shaped, first place the battery top cover on the placing block 16, and then use the first electric push rod 3 to drive the four second electric push rods 5 to move downward through the connecting plate 4, so that the four second electric push rods 5 drive the shaping blocks 6 to move downward respectively. At the same time, the first electric push rod 3 can drive the two extrusion blocks 7 to move downward synchronously;

[0033] When the two extrusion blocks 7 move downward to a proper position, the two extrusion blocks 7 can extrude the inclined plane parts of the two positioning blocks 8 by using the inclined plane parts, so that the two positioning blocks 8 can move away from each other to position the battery top cover on the placing block 16. At the same time, the four shaping blocks 6 that move downward to a proper position can also press and shape the four corners of the positioned battery top cover.

[0034] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
