[0046] A battery box shaping fixture according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0047] The utility model aims to provide an embodiment of a battery box shaping fixture.

[0048] Reference Figure 1 In this embodiment, the battery box 100 has an open box opening, and the box opening has four transition rounded corners 110.

[0049] Reference Figure 2 In this embodiment, a battery box shaping fixture mainly includes a frame 120, an inner shaping component 140 and an outer shaping component 170.

[0050] Reference Figure 3 、 Figure 4 and Figure 5 As for the rack 120, the rack 120 includes a bottom plate 130, which is used to support the battery box 100 with the box opening facing upward, so that the battery box 100 is placed more stably on the shaping fixture.

[0051] In some specific embodiments, the frame 120 also includes a top plate 340 arranged parallel to the bottom plate 130, and several columns 350 connecting the bottom plate 130 and the top plate 340. The top plate 340 is provided with a through groove 360 ​​running through the top and bottom. The through groove 360 ​​is used to accommodate the battery box 100. The external shaping component 170 is provided on the top plate 340, so that it is convenient to install the external shaping component 170 on the frame 120. At the same time, by providing the through groove 360 ​​running through the top and bottom, the top plate 340 can avoid the battery box 100, so that the bottom plate 130 can support the battery box 100.

[0052] Furthermore, the column 350 is detachable, and a second bolt 370 for fixed connection is provided between the column 350 and the base plate 130, and a third bolt 380 for fixed connection is provided between the column 350 and the top plate 340. Thus, by disassembling and replacing columns 350 of different heights, the forming fixture can adapt to battery boxes 100 of different heights, thereby improving the adaptability of the forming fixture to the height of the battery box 100.

[0053] Reference Figure 6 As for the internal shaping component 140, the internal shaping component 140 includes an internal shaping seat 150, which is used to be installed in the box mouth of the battery box 100. The internal shaping seat 150 is abutted against the inner sides of the four side walls of the battery box 100 for shaping, so that the internal shaping seat 150 can support the inner sides of the four side walls of the battery box 100, thereby preventing the four side walls of the battery box 100 from sinking and deforming inward.

[0054] Furthermore, the inner shaping seat 150 has four first notches 160, and the four first notches 160 are used to avoid the four transition fillets 110 of the box opening of the battery box 100, thereby preventing the inner shaping seat 150 from contacting and interfering with the four transition fillets 110 of the box opening of the battery box 100, so that the shape of the four transition fillets 110 of the box opening of the battery box 100 is a shape without interference, and thus, the detection result of the four transition fillets 110 of the box opening of the battery box 100 is more accurate.

[0055] In some specific embodiments, the internal shaping component 140 also includes two support rods 300, which are arranged side by side on the top surface of the internal shaping seat 150, and the two ends of the support rods 300 extend outward from the internal shaping seat 150. The support rods 300 abut against the box opening of the battery box 100 to support the internal shaping seat 150, thereby facilitating the hanging of the internal shaping seat 150 in the box opening of the battery box 100 and preventing the internal shaping seat 150 from falling to the bottom of the battery box 100.

[0056] Furthermore, the support rod 300 is T-shaped, and the support rod 300 includes a horizontal rod portion 310 and a vertical rod portion 320 located at the bottom of the horizontal rod portion 310. The vertical rod portion 320 abuts the top surface of the internal forming seat 150, and the horizontal rod portion 310 is used to abut the box opening of the battery box 100, thereby making the thickness of the part of the support rod 300 connected to the internal forming seat 150 thicker, and thus making the structural strength of the support rod 300 better.

[0057] In some specific embodiments, two first bolts 330 for fixed connection are provided between the support rod 300 and the inner shaped seat 150 , thereby facilitating the disassembly and installation of the support rod 300 and the inner shaped seat 150 .
