Multiple horizontal pressure mechanism 400 realizes the clamping of frame 200 and connecting beam 210 in horizontal direction, and the section bar of partial frame 200 and connecting beam 210 is adjusted in horizontal direction using horizontal pressure mechanism 400, to offset the stress deformation of corresponding section bar after welding. And multiple adjusting part 300 and vertical pressure mechanism 500 realize the clamping of frame 200 and connecting beam 210 in vertical direction, and by changing the support height of adjusting part 300 to adapt to the height of the section bar of different frame, so that the lower surface of all section bars before welding is on the same horizontal plane, so as to ensure the flatness of the frame after welding. Through the above structure, not only can the scattered section bars of multiple battery box frames be clamped and fixed, but also partial section bars can be adjusted in anti deformation, so that multiple section bars can be welded into a complete frame of battery box by only one welding process, which not only avoids the deformation of the welded frame, but also facilitates the welded frame to meet the flatness requirement.

[0028] It can be understood that, referring to Figure 4 , Figure 4The dashed line in the frame is the product deformation after the frame is welded without using the reverse deformation tool. By clamping the frame to be welded, the dashed line profile after the frame is welded can be matched with the ideal profile of the product, thereby ensuring that the frame meets the expected requirements after welding.

[0029] Referring to Figure 1 and Figure 2 , further comprising a first limiting block, the first limiting block is detachably connected to the first mounting seat 410, the first limiting block has a first limiting surface for limiting the movement stroke of the first pressing block 420, thereby changing the limit position of the first pressing block 420 movement, which is beneficial to reserve the space for the corresponding profile to produce pre-deformation in the horizontal direction.

[0031] It can be understood that the reverse deformation adjusting mechanism of the profile in the horizontal direction includes: a fixed plate, a transverse pressing mechanism 400 with a first limiting block, and a transverse pressing mechanism 400 without a first limiting block, which can be combined in pairs to realize three different horizontal profile pressing schemes, which is beneficial to match the pre-deformation adjustment of different profiles in the horizontal direction. The first scheme adopts the transverse pressing mechanism 400 with the first limiting block and the transverse pressing mechanism 400 without the first limiting block. The former reserves the space for the profile to produce pre-deformation in the horizontal direction by adjusting the position of the first limiting block, and the latter directly presses the workpiece without limiting by the first pressing block 420, thereby driving the profile to produce greater pre-deformation adjustment, which can be used for clamping and fixing the left and right profiles of the frame 200 in the horizontal direction. The second scheme adopts the transverse pressing mechanism 400 with the first limiting block and the fixed plate. The workpiece reserves the deformation space of the profile in the horizontal direction by adjusting the fixed position of the first limiting block and the fixed plate on the base 100. The deformation range of this scheme is smaller than that of the first scheme, and can be used for the profile located on the front side of the frame 200, the connecting beam 210 located in the middle and front side of the frame. The third scheme is the transverse pressing without the first limiting block and the fixed plate. The reverse deformation adjustment of this scheme is smaller, mainly plays a role in clamping and fixing the profile in the horizontal direction, and can be used for the profile located on the rear side of the frame 200, and the connecting beam 210 located on the rear side and distributed along the left and right directions.

Specifically, the first driver 430 drives the crank block 450 to rotate, so that the connecting rod 440 drives the first pressing block 420 to move along the sliding rail 101, thereby adjusting the position of the first pressing block 420 in the horizontal direction, and increasing the pressing force of the first pressing block 420 on the frame by the connecting rod 440 mechanism, which is beneficial to ensure that the corresponding profile of the frame has a better pre-deformation range.

[0033] Referring to Figure 1 and Figure 2 , further, the first pressing block 420 includes a mounting plate 421, the mounting plate 421 is connected with a plurality of mounting blocks 422, one end of the mounting block 422 is provided with an abutting block 423, and the plurality of abutting blocks 423 are arranged in parallel with each other, thereby increasing the contact points of the first pressing block 420 and the profile, which is beneficial to stably press the mounting plate 421 on the profile, and further drive the profile to produce better pre-deformation.

[0034] Referring to Figures 1 to 3Further, the first driver 430 and the second driver 530 are air cylinders, the telescopic rods of which are connected to the first pressing block 420 or the second pressing block 520, so that the first pressing block 420 or the second pressing block 520 is driven to move by the air cylinders, and the structure is simple and convenient to install. In some embodiments, the first driver 430 and the second driver 530 can also be replaced by hydraulic cylinders, which are not described in detail here.

[0035] Referring to Figure 1 Further, the adjusting member 300 comprises a support block, and a gasket is detachably stacked above the support block, and the gasket is used to abut against the lower surface of the frame 200 or the connecting beam 210, so that the height of the support block at different positions is adjusted by changing the number of gaskets, so that the bottom surface of the profile at different heights of the frame is located on the same horizontal plane, which is beneficial to ensure that the flatness of the frame after subsequent welding meets the requirements.

[0036] Referring to Figure 1 Further, the positioning structure comprises a positioning block 600 and a driving cylinder 610, and the frame 200 is clamped between one of the transverse pressing mechanisms 400 and the positioning block 600, and the output end of the driving cylinder 610 is connected with a positioning pin, and the frame 200 is provided with a positioning hole for the positioning pin to pass through. It can be understood that the positioning block 600 and the positioning pin are used for positioning in the length direction of the profile. Among them, the positioning of the front and rear profiles located on the frame 200 is realized by the cooperation of the positioning block 600 and the transverse pressing mechanism 400. The positioning of the front and rear profiles located on the frame 200 is realized by the cooperation of the positioning pin and the left and right profiles. During installation, the left and right profiles of the frame 200 are installed first, and after the positioning pin is inserted into the positioning hole of the corresponding profile, the transverse clamping mechanism on the left and right sides of the frame 200 is pressed against the corresponding profile, thereby indirectly realizing the positioning of the front and rear profiles in the length direction.

[0037] Further, the base 100 is provided with a plurality of third drivers, the telescopic ends of which abut against the lower surface of the frame upward, so that the frame after welding is lifted in the vertical direction by the plurality of third drivers, which is beneficial to subsequent people to disassemble the frame. It can be understood that the third driver can be an air cylinder or a hydraulic cylinder, which is not described in detail.

[0038] It can be understood that when adjusting the deformation amount of the profile, according to the bending deformation size of each profile after natural welding, a deformation amount of 2mm is preset first, and then the position of the first limiting block or the number of gaskets is adjusted according to the deformation amount after the reverse deformation. During adjustment, 1mm displacement is used for welding debugging each time, and fine adjustment can also be adjusted by 0.3 to 0.5mm displacement, until the normal distribution of the quality measurement data is qualified, so that people can determine the final deformation adjustment amount according to the data of multiple weldings, which is beneficial to achieve the ideal welding effect of the corresponding profile.

[0039] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the scope of protection includes all possible combinations of the technical features.
