[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 6This utility model provides a technical solution: a welding fixture for assembling a battery box for a new energy vehicle, including a fixture base plate 1. Side-mounted cylinders 2 are symmetrically fixed on both sides of the top of the fixture base plate 1. Rotary clamping cylinders 3 are fixed on one side of the top of the fixture base plate 1 relative to the side-mounted cylinders 2. High-pressure clamping cylinders 4 are symmetrically fixed at both ends of the top of the fixture base plate 1. A box body 5 is provided on the top of the fixture base plate 1 relative to the inner side of the side-mounted cylinders 2, rotary clamping cylinders 3, and high-pressure clamping cylinders 4. The side-mounted cylinders 2 are pushed and connected to both sides of the box body 5. The high-pressure clamping cylinders 4 are clamped and connected to the rotary clamping cylinders 3 and the box body 5. A first welding support rod 6 is provided on the top of the box body 5. A snap-fit ​​groove 8 is symmetrically opened at the bottom end of the first welding support rod 6, and the snap-fit ​​groove 8 is snap-fitted to the top of the box body 5. A second welding support rod is provided on the inner side of the box body 5. 7. Both the first welding support rod 6 and the second welding support rod 7 are composed of two equal cuboids. An adjustable length mechanism is provided between the two cuboids. The adjustable length mechanism includes a connecting groove 100 opened at the end of one cuboid and a connecting block 101 fixed at the end of the other cuboid. The connecting block 101 is engaged with the connecting groove 100. An operating handle 102 is fixed at the top of each cuboid. The tooling base plate 1 provides a stable bearing foundation for each component. The side top, rotation clamping, and strong clamping cylinders realize the precise positioning and stable clamping of the box 5 from different directions to ensure the fit during welding. The adjustable length mechanism of the first and second welding support rods (the connecting block 101 is engaged with the connecting groove 100) can be adapted to box 5 of different sizes. The operating handle is easy to adjust manually, improving the tooling versatility and ease of operation.

[0022] In this embodiment, preferably, a through groove 200 is formed on the surface of the connecting block 101, and a fixing block 201 is fixed inside the connecting groove 100, passing through the inside of the through groove 200. The fixing block 201 is slidably connected to the through groove 200. The slidable connection between the through groove 200 and the fixing block 201 provides guidance for adjusting the length of the welding support rod, ensuring a smooth adjustment process, preventing the connecting block 101 from shifting, ensuring the straightness of the length adjustment, and enhancing the structural stability.

[0023] In this embodiment, preferably, the end of the fixing block 201 is provided with a through hole 300, and a fixing rod 301 that passes through the through hole 300 is fixed inside the through groove 200. The fixing rod 301 is engaged with the through hole 300. The engagement of the fixing rod 301 with the through hole 300 limits the sliding of the connecting block 101 in the connecting groove 100, preventing the connecting block from disengaging from the connecting groove 100 during adjustment, thereby improving the safety and structural reliability of the adjustment process.

[0024] In this embodiment, preferably, the top of the connecting block 101 is provided with a screw groove 400, and the top of the inner end of the connecting groove 100 is provided with a locking hole 401. The top of one of the cuboids is provided with a locking rod 402 that is screwed into the locking hole 401. The locking rod 402 is pressed and fitted into the screw groove 400. The cooperation between the locking rod 402 and the locking hole 401 and the screw groove 400 can quickly lock the connecting block 101 after length adjustment, avoid the support rod length from loosening during welding, ensure support accuracy, and ensure the stability of the welding dimensions of the box 5.

[0025] In this embodiment, preferably, the snap-fit ​​groove 8 is provided with a compression assembly. The compression assembly includes a compression plate 500 disposed inside the snap-fit ​​groove 8. A rubber pad 501 is fixed to the end of the compression plate 500. The rubber pad 501 is in close contact with the housing 5. The compression plate 500 and the rubber pad 501 of the compression assembly can be tightly attached to the housing 5 by compression, which enhances the snap-fit ​​firmness between the support rod and the housing 5. At the same time, the rubber pad 501 can buffer the pressure and prevent the surface of the housing 5 from being damaged by pressure.

[0026] In this embodiment, preferably, a guide groove 600 is symmetrically provided on one side of the inner wall of the snap-fit ​​groove 8, and a guide rod 601 adapted to the guide groove 600 is symmetrically fixed at the end of the extrusion plate 500. The guide rod 601 is snapped into the guide groove 600. The snapping of the guide groove 600 and the guide rod 601 provides guidance for the movement of the extrusion plate 500, ensuring that the extrusion plate 500 always moves in a straight line, ensuring that the extrusion force is evenly applied to the box 5, and improving the snapping stability.

[0027] In this embodiment, preferably, a screw hole 700 is provided through one side of the inner wall of the snap-fit ​​groove 8. An adjusting screw 701 is provided on the side of the first welded support rod 6 and is screwed into the screw hole 700. A bearing 702 is connected between one end of the adjusting screw 701 and the extrusion plate 500. An operating button 703 is provided on the side of the first welded support rod 6 and is fixedly connected to the adjusting screw 701. The screwing fit between the adjusting screw 701 and the screw hole 700 allows for precise adjustment of the extrusion force of the extrusion plate 500 by rotating the operating button. The bearing 702 ensures that the extrusion plate does not rotate with the screw during adjustment, thus achieving adaptive pressing for boxes 5 of different thicknesses. The operation is flexible and highly accurate.

[0028] The working principle and usage process of this utility model are as follows: When it is necessary to adjust the length of the welding support rod according to the size of the box 5, first loosen the locking rod 402 so that its end exits from the inside of the screw groove 400 and screws into the inside of the locking hole 401. This releases the positioning of the connecting block 101. Then, by operating the handle 102, pull the welding support rod to both sides. This will cause the connecting block 101 to slide inside the connecting groove 100 to extend the length of the welding support rod. At the same time, it will cause the through groove 200 to slide on the surface of the fixing block 201 to play a guiding role. Simultaneously, it will cause the through hole 300 to slide on the surface of the fixing rod 301 to play a guiding role. The function of the movement limit is to stop pulling the operating handle 102 when the welding support rod extends to the appropriate length, so that the connecting block 101 stops moving inside the connecting groove 100. Then, tighten the locking rod 402 so that it rotates inside the locking hole 401 and presses against the screw groove 400, thus locking the position of the connecting block 101 inside the connecting groove 100. After adjusting the first welding support rod 6 and the second welding support rod 7, the second welding support rod 7 is engaged with the housing 5. Then, the first welding support rod 6 is engaged with the top of both sides of the housing 5 through the engaging groove 8. Then, turn the operating button 703 to... It drives the adjusting screw 701 to rotate inside the screw hole 700, and pushes the extrusion plate 500 to move through the bearing 702, so that the extrusion plate 500 is pressed against the side of the box 5 through the rubber pad 501. At the same time, when the extrusion plate 500 moves, it drives the guide rod 601 to slide inside the guide groove 600, which plays a moving guiding role, thus pressing the box 5 and making the first welding support rod 6 firmly engaged with the box 5 to facilitate welding work. When clamping and installing the box 5, the tooling base plate 1 is used as the bearing base, and the positioning block is used to initially limit the position of the box 5 frame. Then, the maximum thrust of the five side top cylinders 2 is 150. KG pushes the housing 5 onto the positioning block for precise alignment. Simultaneously, multiple welded support rods ensure the parallelism and perpendicularity of the four sides of the housing 5, maintaining structural stability. Subsequently, six large rotary clamping cylinders 3 with a maximum pressure of 160KG and four powerful clamping cylinders 4, which can be operated automatically or manually, clamp the frame from key nodes and edges, ensuring tight fit of components during welding. Finally, after positioning, support, and clamping, the assembled housing 5 frame is welded. After welding, each cylinder returns to its original position, thus achieving batch, efficient, and stable battery housing welding operations, replacing traditional manual assembly and welding methods, reducing labor costs, and ensuring welding quality.
