Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, specifically a welding tooling for a bracket used in battery production. Background Technology

[0002] Bracket welding fixtures are process equipment used to accurately position and reliably clamp products to be welded, facilitating assembly and welding. They have wide applications in the manufacturing industry, especially in battery welding production. Because battery welding requires high precision, manual welding can easily lead to excessive errors. Bracket welding fixtures can effectively meet the requirements of battery welding.

[0003] In existing technologies, the welding fixtures for batteries on the market cannot be well adapted to different battery models due to the different sizes and shapes of the batteries. This makes it inconvenient to clamp and fix multiple sets of batteries in batches, which affects the production of multiple battery models, is not conducive to improving production efficiency, and leads to increased production costs. To address this, we propose a bracket welding fixture for battery production. Utility Model Content

The adjustment component includes a first screw 4, a sliding member 5, a sliding groove 6, a connecting rod 7, and a first motor 8. The base 1 is rotatably connected to the first screw 4. One end of the first screw 4 is connected to the output end of the first motor 8. A set of sliding members 5 is threaded to the outside of both ends of the first screw 4. The sliding members 5 can slide along the sliding groove 6 opened in the base 1. Each set of sliding members 5 is hinged to two sets of connecting rods 7. The two sets of connecting rods 7 are respectively hinged to the two sets of second limiting members 3.

[0024] In this embodiment, the first screw 4 is a reversible screw. By starting the first motor 8, the first screw 4 is driven to rotate, causing the sliding member 5, which is threadedly connected to it, to slide along the slide groove 6. The distance between the two sets of sliding members 5 is adjusted, and a V-shaped structure is formed between the sliding member 5 and the connecting rod 7. By moving the two sets of sliding members 5 away from each other, the V-shaped structure can be contracted, which can drive the two sets of second limiting members 3 to move closer to each other, reducing the space of the clamping chamber formed between them and the first limiting member 2. Conversely, it can be expanded. Compared with the prior art, it is convenient to clamp and fix multiple sets of batteries in batches, and it is convenient to adapt to different models of batteries, so as not to affect the production of multiple battery models and improve production efficiency.

[0025] Please refer to Figure 1-4 As shown, the first limiting member 2 includes a first baffle 9 and a second baffle 10. Two sets of first baffles 9 are provided. Multiple sets of second baffles 10 are installed at equal intervals between the two sets of first baffles 9. The second baffles 10 are slidably connected to the two sets of second limiting members 3. The sliding member 5 includes a first slider 11 and a second slider 12. The first slider 11 is threadedly connected to the first screw 4. The second slider 12 is installed at the top of the first slider 11. The second slider 12 is hinged to two sets of connecting rods 7.

[0026] In this embodiment, the first baffle 9 is connected to the base 1, and a clamping chamber is formed between two adjacent sets of second baffles 10 and two sets of second limiting members 3, which can clamp the battery. The first slider 11 is threadedly connected to the first screw 4, which can drive the second slider 12 to move. The second slider 12 is hinged to the connecting rod 7, which can realize the adjustment of the second limiting member 3.

[0027] Please refer to Figure 1-4As shown, a first support base 13 is connected to one side of the base 1 via a lifting assembly. The first support base 13 is connected to a second support base 14 via a moving assembly. The second support base 14 is equipped with a slidable welded assembly. The lifting assembly includes an electric push rod 15 and a third baffle 16. Two sets of electric push rods 15 are symmetrically installed on one side of the base 1. The electric push rods 15 are connected to the third baffle 16, which is connected to the first support base 13. The moving assembly includes a second screw 17, a second motor 18, and a third slider 19. A rotatable second screw 17 is installed inside the cavity of the first support base 13. One end of the second screw 17 is connected to the output end of the second motor 18. The second screw 17 is threadedly connected to the third slider 19, which is slidably installed in the inner cavity of the first support base 13. The third slider 19 is connected to the second support base 14. The second support base 14 is connected to a slidable welding assembly, which includes a fourth slider 20, a spot welding machine 21, and a fastening bolt 22. The slidable fourth slider 20 is sleeved on the outside of the second support base 14. The spot welding machine 21 is installed at the bottom end of the fourth slider 20. The fastening bolt 22 is threadedly connected to the top end of the fourth slider 20. The fastening bolt 22 can penetrate the fourth slider 20.

[0028] In this embodiment, by sliding the fourth slider 20 along the second support base 14, the position of the spot welding machine 21 can be adjusted. Then, by tightening the fastening bolt 22, the position of the fourth slider 20 can be locked. By starting the second motor 18, the second screw 17 is rotated, causing the third slider 19, which is threaded to it, to move, thereby moving the second support base 14 and adjusting the position of the spot welding machine 21. By retracting the electric push rod 15, the first support base 13 can be lowered, thereby lowering the spot welding machine 21, which facilitates welding of the battery tabs.

[0029] Working principle: First, the first baffle 9 is connected to the base 1. Adjacent sets of second baffles 10 and two sets of second limiting members 3 form a clamping chamber to hold the battery. The first slider 11 is threadedly connected to the first screw 4, which can drive the second slider 12 to move. The second slider 12 is hinged to the connecting rod 7, allowing adjustment of the second limiting members 3. The first screw 4 is a reversible screw. By starting the first motor 8, the first screw 4 rotates, causing the threaded sliding member 5 to slide along the slide groove 6, adjusting the distance between the two sets of sliding members 5. The sliding member 5 and the connecting rod 7 form a V-shaped structure. By moving the two sets of sliding members 5 away from each other, the V-shaped structure retracts, causing the two sets of second limiting members 3 to move closer together, thus accommodating the space of the clamping chamber formed between the second and first limiting members 2. The size can be reduced, and vice versa. Compared with existing technologies, it is convenient to clamp and fix multiple sets of batteries in batches, and it is convenient to adapt to different battery models, so as not to affect the production of multiple battery models and improve production efficiency. By sliding the fourth slider 20, it can slide along the second support seat 14 to adjust the position of the spot welding machine 21. Then, tightening the fastening bolt 22 can lock the position of the fourth slider 20. By starting the second motor 18, the second screw 17 is driven to rotate, which moves the third slider 19 connected to it by thread, thereby moving the second support seat 14 and adjusting the position of the spot welding machine 21. By retracting the electric push rod 15, the first support seat 13 can be lowered, which can also lower the spot welding machine 21 to facilitate welding of battery tabs.
