Description

Technical Field

[0001] The utility model relates to the technical field of battery welding, in particular to a busbar limiting tool. Background Art

[0002] The individual cells of a power battery pack can be connected in series or in parallel to form a power battery pack to meet the various power requirements of the vehicle. The electrodes of each individual cell are connected accordingly to form a series or parallel connection between the individual cells to form a power battery pack. Therefore, a bus is required to connect the positive and negative poles of the battery cells.

[0003] Publication number CN218856025U discloses a limiting fixture for welding a battery cell busbar, comprising a welding platform, wherein a limiting cavity is provided on the welding platform, the limiting cavity corresponding to the pole of the battery cell, and is used to place the busbar; and further comprising a limiting clamp, wherein the limiting clamp is provided on the outside of the limiting cavity, and is used to clamp the busbar in the limiting cavity. Although this type of limiting fixture can increase the contact area with the busbar by providing abutting portions, multiple abutting portions can clamp the busbar from multiple points, thereby improving the stability of the clamping. However, this type of limiting fixture is difficult to effectively prevent the busbar from being displaced during operation or work, resulting in a low fixing accuracy of the busbar during installation, which is prone to position deviation, thereby affecting the precise installation of the busbar, increasing the error rate, and reducing the overall reliability of the fixture system. Therefore, improvements are needed. Utility Model Content

[0010] Preferably, the extrusion block is made of natural rubber, and the short rod is slidably connected to the limit block.

[0011] Preferably, the number of the short rods is two groups.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] 1. The utility model avoids the displacement of the bus by designing a limit block, ensures that the position of the bus on the tooling is fixed, improves the fixing accuracy during the installation process, and reduces the error caused by displacement. At the same time, the use of the limit block can effectively prevent the bus from loosening or offsetting during operation or work, provides better mechanical stability, and thus improves the shortcomings of the existing tooling system in the module. When installing the limit block, it is only necessary to align the limit block with the slot and insert it, and then release the handle. The limiting process will be automatically completed by the tension of the tension spring A, without the need for complicated manual adjustment, which greatly simplifies the operating steps and reduces the difficulty of operation. At the same time, the limit can be quickly released by simply pulling the handle, which makes the disassembly and assembly of the limit block more convenient and efficient, and reduces the time cost of assembly and maintenance. The tension of the tension spring A can automatically pull the handle to drive the insertion rod to insert the jack, forming the function of automatically locking the limit block. No additional operation is required, and automatic limiting is achieved, which improves the convenience and reliability of operation.

[0014] 2. The present invention uses the tension of the tension spring B to drive the movement of the back block and the short rod, thereby causing the extrusion block to press the busbar. This design can provide additional pressing force for the busbar, ensuring that the busbar will not loosen or shift during installation, significantly improving the firmness of the fixation. At the same time, under the linkage of the tension spring B and the short rod, the extrusion block can automatically adjust the pressing position according to the size of the busbar. Compared with traditional fixing methods, this design can flexibly adapt to buses of different sizes and shapes without the need for manual adjustment of the limit structure, thereby enhancing the adaptability and versatility of the tooling. At the same time, due to the action of the tension spring B, the entire extrusion process is automatic and can provide uniform and moderate pressure. In this way, the busbar can be firmly fixed without being damaged, avoiding the problem of excessive or insufficient clamping that may be caused by manual operation, and is highly practical.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] See also Figure 1-4 The present invention provides a technical solution: a busbar limiting tooling, comprising a welding platform 1, a limiting cavity 2 and a slot 3 are provided on the top surface of the welding platform 1, and the limiting cavity 2 is arranged at equal distances on the top surface of the welding platform 1 so as to maintain a good limiting effect when installing different busbars. A limiting block 4 is placed on the inner wall of the slot 3, and the limiting blocks 4 are distributed at the four corners of the top surface of the welding platform 1 to ensure multi-point stable support of the busbar. The limiting block 4 can be connected to the slot 3 by bolt fixing, snap connection or interference fit. The bolt fixing method can ensure the firmness of the installation of the limiting block 4, the snap connection is convenient for disassembly and installation, and the interference fit can achieve a more precise limiting effect. A top groove 5 is provided on the top surface of the welding platform 1, and the inner wall of the top groove 5 is slidably connected to a slide groove 6, and the inner wall of the slide groove 6 is slidably connected to a slider 7. This sliding connection can be achieved by a guide rail or a bearing. The guide rail can ensure the stability and precision of the slider 7 during movement, while the sliding of the bearing can reduce friction and improve movement efficiency.

[0025] See also Figure 1-4 A moving block 8 is fixedly installed on the top of the slider 7. The material of the moving block 8 can be selected from high-strength alloy or engineering plastic to ensure that it has sufficient wear resistance and strength and is not easy to deform. A plug rod 9 is set through the side of the moving block 8. The plug rod 9 is slidably connected to the moving block 8. This sliding connection can be achieved through threads or linear bearings. The threaded connection can ensure the stability of the plug rod 9 when it is fixed, and the linear bearing can provide smooth sliding performance. A pull handle 10 is fixedly installed at one end of the plug rod 9. The pull handle 10 can be made of wear-resistant plastic or stainless steel. The plastic material is light and easy to operate, while the stainless steel material is more durable and can withstand the tension during operation for a long time. A tension spring A11 is sleeved on the surface of the plug rod 9. One end of the tension spring A11 is fixedly connected to the pull handle 10, and the other end is fixedly connected to the moving block 8. The tension spring A11 can be made of spring steel material, which has excellent elasticity and durability, can continuously provide stable tension, and ensure that the plug rod 9 can be quickly reset during operation. The side of the stopper 4 is provided with a socket 12, which is sized to fit the rod 9. When the rod 9 is inserted into the socket 12, the stopper 4 is securely locked. The insertion of the rod 9 is powered by a tension spring A11. This design ensures that the stopper 4 automatically locks during installation, making operation simple and reliable. To remove the stopper 4, simply pull the rod 9 outward using the handle 10 until it clears the socket 12. This releases the stopper 4, allowing for easy removal. This simplifies the assembly and disassembly process and reduces time and effort.

[0026] Example 2

[0027] See also Figure 4 The surface of the limit block 4 is provided with a close-fitting mechanism, which includes a short rod 13. There are two groups of short rods 13, which are arranged on the surface of the limit block 4. One end of the short rod 13 is fixedly installed with an extrusion block 14. The extrusion block 14 is made of natural rubber. Natural rubber has good softness and elasticity, which can effectively prevent the bus from being damaged when being squeezed. The extrusion block 14 can be connected to the short rod 13 by bolts or gluing. Such a connection method ensures the stability of the extrusion block 14. The short rod 13 is slidably connected to the limit block 4. This sliding connection can be achieved by a slide rail or a bearing. The guide rail can ensure the stable movement of the short rod 13, while the bearing can reduce friction and improve sliding efficiency. The other end of the short rod 13 is fixedly installed with a back block 15. A tension spring B16 is fixedly installed between the back block 15 and the limit block 4. The material of the tension spring B16 can also be spring steel to ensure that it has sufficient strength and durability.

[0028] Working principle: The problem of poor stability of the existing tooling on the module is solved by setting the limit block 4. The limit block 4 can avoid the displacement of the busbar, thereby improving the fixing accuracy. At the same time, when installing the limit block 4, you only need to align the limit block 4 with the slot 3 and then release the handle 10. At this time, due to the tension of the tension spring A11, the tension spring A11 can pull the handle 10 to move, and the handle 10 can then drive the insertion rod 9 to insert into the socket 12. At this time, the limit block 4 can be limited. When removing the limit block 4, you only need to pull the insertion rod 9 outward through the handle 10 until the insertion rod 9 leaves the socket 12. At this time, the limit can be cancelled. The limit of the positioning block 4 makes it easy to remove the positioning block 4. The utility model avoids the displacement of the bus by designing the positioning block 4, ensures that the position of the bus on the tooling is fixed, improves the fixing accuracy during the installation process, and reduces the error caused by displacement. At the same time, the use of the positioning block 4 can effectively prevent the bus from loosening or offsetting during operation or work, provides better mechanical stability, and thus improves the shortcomings of the existing tooling system in the module. When installing the positioning block 4, it is only necessary to align the positioning block 4 with the slot 3 and insert it, and then release the handle 10. The limiting process will be completed through the tension of the tension spring A11. The force is automatically completed without complicated manual adjustment, which greatly simplifies the operation steps and reduces the difficulty of operation. At the same time, the limit can be quickly released by simply pulling the handle 10, which makes the disassembly and assembly of the limit block 4 more convenient and efficient, and reduces the time cost of assembly and maintenance. The tension of the tension spring A11 can automatically pull the handle 10 to drive the insertion rod 9 to insert into the socket 12, forming the function of automatically locking the limit block 4, without additional operation, realizing automatic limit, and improving the convenience and reliability of operation. The tension spring B16 set can pull the back block 15 to move due to the tension, and the back block 15 The short rod 13 can then be driven to move, and the short rod 13 can then drive the extrusion block 14 to press against the busbar, which can more firmly fix the busbar and adapt to busbars of different sizes. The utility model uses the tension of the tension spring B16 to drive the movement of the back block 15 and the short rod 13, thereby causing the extrusion block 14 to press the busbar. This design can provide additional compression force for the busbar, ensuring that the busbar will not loosen or shift during installation, significantly improving the firmness of the fixation. At the same time, under the linkage of the tension spring B16 and the short rod 13, the extrusion block 14 can automatically adjust the compression position according to the size of the busbar. Compared with traditional fixing methods, this design can flexibly adapt to busbars of different sizes and shapes without manually adjusting the limit structure, enhancing the adaptability and versatility of the tooling. At the same time, due to the action of the tension spring B16, the entire extrusion process is automatic and can provide uniform and appropriate pressure. In this way, the busbar can be firmly fixed without being damaged, avoiding the problem of excessive or insufficient clamping that may be caused by manual operation.
