[0030] According to an embodiment of the utility model, a battery pack trimming device is provided.

[0031] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4 As shown, a battery pack trimming device according to an embodiment of the utility model includes an operating table 1 and a base 9, an adjusting disk 4 is rotatably connected to the middle position on the top of the operating table 1, one end of the adjusting disk 4 passes through one side of the operating table 1 and is connected to the brake motor 2, a plurality of groups of hydraulic rods 3 are symmetrically installed on both sides of the adjusting disk 4 at the top position of the operating table 1, a connecting plate 7 is fixedly installed at the top position between the hydraulic rods 3, a cutting knife 8 is fixedly installed at the bottom position of the connecting plate 7, a receiving groove 5 is opened at the middle position on the top of the adjusting disk 4, and a standard block 6 is abutted against the inner position of the receiving groove 5.

[0032] In one embodiment, support arms 10 are symmetrically installed on both sides of the bottom of the operating table 1, and a base 9 is fixedly installed at the bottom of the support arms 10. The entire device can be fixed by the support arms 10 and the base 9 to facilitate enhancing the overall stability of use.

[0033] In one embodiment, the structure of the receiving groove 5 is the same as the outer surface structure of the battery pack after stamping. The receiving groove 5 is provided to accommodate the battery pack so that its excess corners can be exposed outside the receiving groove 5, thereby facilitating subsequent trimming. At the same time, with the insertion of the standard block 6, the structure of the battery pack can be further restricted so that its excess corners can be more fully exposed, facilitating subsequent trimming and ensuring trimming accuracy.

[0034] In one embodiment, the structure of the standard block 6 is the same as the internal groove structure of the battery pack after stamping. The standard block 6 is provided to limit the extrusion of the battery pack after stamping to prevent movement during trimming, thereby ensuring the stability of trimming and the accuracy of trimming.

[0035] In one embodiment, a bracket for installing the brake motor 2 is installed in the middle of the bottom of the operating table 1. The bracket is provided to provide an installation platform for the brake motor 2. The type of the bracket is not marked in the figure, and personnel can easily purchase it on the market, so it will not be elaborated on.

[0036] In one embodiment, the spacing between the hydraulic rods 3 is larger than the size of the adjusting disk 4. The spacing between the hydraulic rods 3 is set to ensure that it will not affect the rotation of the adjusting disk 4, thereby ensuring that different sides of the battery pack can be cut later, thereby improving the overall cutting effect.

[0037] In one embodiment, the size of the cutting knife 8 is larger than the size of the battery pack. The size of the cutting knife 8 is set to ensure that the excess parts of the corners of the battery pack can be fully cut to ensure the trimming effect.

[0038] In one embodiment, a slot is provided at the top of the operating table 1 for the adjustment disk 4 to rotate. The slot is provided to limit the rotation trajectory of the adjustment disk 4 and to support it at the same time.

[0039] Working principle: In actual use, personnel can place the stamped battery pack into the receiving slot 5, and then press the standard block 6 into the receiving slot 5. At this time, the structures of the receiving slot 5 and the standard block 6 are set according to the outer shape of the battery pack after stamping and the shape of the internal depression. Therefore, the two can fully wrap and squeeze the battery pack. At this time, the excess part around the battery pack can be exposed at the top position of the receiving slot 5, and then the connecting plate 7 can be driven to move downward as a whole by retracting the hydraulic rods 3 on both sides, so that the cutting knife 8 on the surface can move along the side of the standard block 6, thereby realizing the trimming operation on both sides of the battery pack. Then, after the trimming on both sides is completed, the operation of the brake motor 2 can drive the adjustment disk 4 to rotate as a whole. , so that the battery pack can be rotated ninety degrees, so as to move the untrimmed positions on the other two sides to the position directly below the cutting knife 8. Since the side lengths of the battery packs are different, the setting position of the cutting knife 8 is set accordingly according to the different positions of the different sides after the battery pack is rotated. In this way, it can be ensured that the cutting knife 8 can accurately perform trimming operations on all sides of the battery pack, thereby improving the overall cutting effect. The device can cut both sides at one time, and after the cutting is completed, it can be automatically turned by the brake motor 2 without manual operation. Not only can the risk of misalignment during transfer be avoided, but also the labor intensity of personnel can be reduced, the work efficiency can be improved, and the cutting accuracy can be ensured. The device as a whole has the advantages of high cutting efficiency, high cutting accuracy, and labor-saving operation.
