Description

Technical Field

[0001] The present invention relates to the technical field of cooling module processing, and in particular to a leveling device for an aluminum die-cast battery pack cooling module. Background Art

[0002] With the booming development of the new energy vehicle industry, the battery pack, as one of its core components, has a crucial impact on the performance of the entire vehicle due to the manufacturing quality of its structural parts. The aluminum die-cast battery pack cooling module consists of an aluminum alloy cover plate (or aluminum die-cast upper shell plate) and an aluminum die-cast lower shell plate. The shell plate is long and flat due to design requirements. During the production process, the aluminum alloy cover plate (or aluminum die-cast upper shell plate) and the aluminum die-cast lower shell plate are sealed by friction welding to form a tight assembly to ensure the sealing and structural stability of the battery pack.

[0003] However, in actual production, aluminum die-cast shells inevitably deform to a certain degree after forming due to factors such as temperature changes and gravity. If this deformation is not effectively controlled, it will directly affect subsequent assembly accuracy and product quality. To complicate matters further, while friction welding can achieve efficient welding, the assembly often shrinks and deforms during the cooling process due to thermal expansion and contraction. This shrinkage not only destroys the flatness of the assembly but also causes dimensional accuracy to exceed the tolerance range, thereby affecting the overall performance and reliability of the battery pack and posing a significant challenge to manufacturing.

[0004] To address the problem of structural component deformation, the industry has conducted numerous explorations and experiments. For example, patent CN222790203U discloses a panel shaping device. This device utilizes a lifting plate, shaping member, top plate, base, positioning member, and a press drive cylinder. The curved surface of the shaping member interacts with the protective cloth, and the press drive cylinder drives the device to flatten the injection-molded panel, effectively reducing the degree of curvature of the finished panel. This device boasts a simple structure, easy processing, and low cost, providing a viable approach for shaping similar structural components.

[0005] Patent CN222858279U discloses a plywood shaping cold press, which innovatively designs a bidirectional mechanism and a clamping mechanism. The bidirectional screw is driven by a motor, which drives the screw seat and the clamping plate to move, thereby achieving extrusion limitation on both sides of the plywood, avoiding sliding and offset of the plywood during shaping. At the same time, with the help of the rolling mechanism and the shaping mechanism, the unloading and shaping processing of the plywood are facilitated, which significantly improves the shaping quality of the plywood and provides a useful reference for the shaping process of structural parts of different materials.

[0006] Patent CN119733777A discloses a side pressure shaping mold for the side outer panel. To address the wrinkling problem of the negative-angle flange side shaping in the front windshield area of ​​the side outer panel of new energy vehicles, it cleverly adopts a lower-mounted inclined wedge mechanism, an integrated side pressure plate, and a series of innovative designs such as side pressure nitrogen springs to offset the lateral force of the main pressure plate, oppositely arranged shaping inserts to balance the side shaping overload, and conical balancing blocks to ensure the working balance of the main pressure plate. These designs effectively solve the wrinkling problem. The mold has a compact structure, low cost, and high reliability, providing an advanced example for the design of high-precision shaping molds for complex structural parts.

[0007] Patent CN120079716A discloses a linear module base shaping device, which consists of a base frame, an external shaping component and an internal shaping component. The outer guide wheel and the reference plate of the outer shaping component are adjustable left and right, and the inner guide wheel and the outer guide wheel of the inner shaping component form a guide channel, which can flexibly adapt to the shaping needs of linear module bases of different specifications, avoid frequent customization or replacement of the shaping device, improve production efficiency and product quality, and provide a new direction for the flexibility and adaptability design of structural parts shaping devices.

[0008] Patent CN222739967U discloses a fixture structure for flat plate shaping. Through the cooperation of a punch press, a base, a workbench and a sliding component, the flat plate is limited by the positioning parts on the workbench, and then the part of the flat plate to be shaped is moved to the bottom of the punch press circular axis for shaping through the sliding component. This simplifies the shaping steps, reduces manual operations, improves the shaping speed and forming quality, and provides an effective solution for optimizing the shaping process of flat plate structural parts.

[0009] While the aforementioned patents provide diverse technical approaches and innovative approaches for structural component shaping within their respective fields, they still face certain limitations when addressing the flatness and dimensional accuracy issues of aluminum die-cast battery pack cooling module assemblies caused by deformation during forming of the aluminum die-cast lower shell plate and shrinkage deformation after friction welding. Existing technologies have yet to fully meet the specific needs for high-precision shaping of aluminum die-cast battery pack cooling module assemblies. Therefore, it is urgent to develop an efficient and precise shaping process and equipment specifically for such assemblies to overcome the shortcomings of existing technologies, ensure high-quality production of battery pack cooling module assemblies, and meet the rapid development requirements of the new energy vehicle industry.

[0064] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0067] like Figure 1-10 As shown, this embodiment provides a leveling device for aluminum die-cast battery pack cooling modules. The device is intended to level an aluminum die-cast battery pack cooling module 100 that has been deformed after friction welding. The module 100 comprises a body 101, an upper plate 102 located on the second side of the body 101 in the width direction and extending beyond the upper surface of the body 101, and a lower plate 103 located on the second side of the body 101 in the width direction and extending beyond the lower surface of the body 101. The body 101 bulges upward during the friction welding heat deformation, while the upper and lower plates 103 slightly collapse toward the first side due to die-casting demolding.

[0068] like Figure 1-2As shown, the flattening apparatus comprises a base plate 1 and spaced guide blocks 2, which together form a shaping station 20. The support surfaces 21 of the guide blocks 2 are used to support the lower surface of the aluminum die-cast battery pack cooling module 100 to be machined. Multiple guide blocks 2 form a rigid support matrix, with the support surfaces 21 contacting the lower surface of the module.

[0069] like Figure 1-4 As shown, a vertically movable shaping block 23 is positioned in the middle of the guide seat 2. This block 23 rises to push the body 101 upward. Furthermore, a clamping assembly 6 is positioned on either side of the shaping station 20 to secure the body 101. This assembly is used to secure the ends of the aluminum die-cast battery pack cooling module 100 being processed and to level the ends. The clamping assembly 6 simultaneously compresses the ends of the module, securing them so that the shaping force is evenly transmitted along the length, forming a closed mechanical loop of fixed ends and shaping the center.

[0070] Furthermore, if Figure 6 As shown, a plurality of pressing shaping components 7 are provided on the first side of the width direction of the shaping position 20, and the pressing shaping components 7 are used to press down the first side of the body 101. They are used to fix the side of the aluminum die-cast battery pack cooling module 100 to be processed and level the side.

[0071] like Figure 2 、 3 As shown in Figures 9 and 10, a long pressing plate 3 is provided on the second side of the guide seat 2 in the width direction of the shaping position 20. The long pressing plate 3 is connected to the guide seat 2 through a guide rod 4 so that it can move closer to and farther away from the guide seat 2.

[0072] like Figure 1 、 3 As shown in FIG8 , a lateral slide 9 is provided on the second side of the shaping position 20 in the width direction. The lateral slide 9 moves along the slide rail 90 on the base plate 1 to approach or move away from the shaping position 20.

[0073] like Figure 9 、 10 As shown, the lateral slide 9 includes a clamping assembly 5 and an upper side pressing and shaping assembly 8. The clamping assembly 5 drives the long pressing plate 3 to squeeze the lower side plate 103 toward the second side and limit the lateral slide 9 from moving away from the shaping position 20. The upper side pressing and shaping assembly 8 squeezes the upper side plate 102 toward the second side.

[0074] like Figure 1 、 3 As shown, a limiting column 10 is provided on the first side of the shaping position 20 in the width direction to limit the position of the aluminum die-cast battery pack cooling module 100 to be processed.

[0075] The method for leveling an aluminum die-cast battery pack cooling module using the leveling equipment includes the following steps:

[0076] Step A: In the initial state, the clamping assembly 5 is separated from the long pressing plate 3, and the lateral slide 9 is away from the shaping position 20.

[0077] Step B: Place the aluminum die-cast battery pack cooling module 100 to be processed, which is deformed and bulges upward, into the shaping position 20 formed by the guide seat 2, and the support surface 21 of the guide seat 2 supports the body 101 upward. Figure 6 shown.

[0078] Step C: The shaping assembly 7 presses down the first side of the main body 101 , and the holding assembly 6 holds both ends of the main body.

[0079] Step D: The lateral slide 9 is driven to approach the shaping position 20 , and the clamping assembly 5 drives the long pressing plate 3 to move away from the shaping position 20 .

[0080] Step E: The first side pressing surface 302 is located on the first side of the lower side plate 103 to press the lower side plate 103 toward the second side, and the clamping assembly 5 restricts the lateral slide 9 from moving away from the shaping position 20 .

[0081] Step F: The upper side pressure shaping assembly 8 is driven to press the upper side plate 102 toward the second side. Figure 7 shown.

[0082] Step G: At the same time, the holding assembly 5 rotates downward to release the long pressing plate 3, the upper side pressing shaping assembly 8 moves upward to leave the upper side plate 102, and the downward pressing shaping assembly 7 moves away from the main body 101.

[0083] Step H: The shaping block 23 rises and applies an upward force to the body 101, causing the aluminum die-cast battery pack cooling module 100 to be processed to deform upward. Figure 8 shown.

[0084] Step I: The shaping blocks 23 are lowered in sequence and held for a period of time, and the holding assembly 6 is released. The aluminum die-cast battery pack cooling module 100 to be processed returns to a free state, and the main body 101 undergoes plastic deformation and is adjusted from a bent state to a horizontal state.

[0085] This leveling method can effectively solve the problem of upward bulging and deformation of the cooling module of the aluminum die-cast battery pack. Through a series of orderly steps, such as the coordinated action of the downward pressure shaping component 7 and the side pressure shaping component, the bent module can be accurately adjusted to a horizontal state, ensuring that the flatness of the module meets strict production standards, thereby improving the overall assembly accuracy of the battery pack. The entire leveling process can be achieved through automated equipment and programs. From the setting of the initial state in step A to the completion of the final restoration of the free state in step I, the actions and steps of each component are automatically executed in a certain logical order, reducing manual intervention, improving processing efficiency, and meeting the needs of large-scale production. The various steps are closely connected. The clamping component 5 rotates downward to release the long pressure plate 3, the upper side pressure shaping component 8 moves upward to leave the upper side plate 102, and the downward pressure shaping component 7 separates from the body 101 almost simultaneously. This efficient coordinated action greatly shortens the cycle of the entire leveling operation. At the same time, the orderly coordination of the various components avoids the risk of secondary deformation caused by improper human or equipment operation during the leveling process of the module. In steps D and E, the clamping assembly 5 limits the movement of the lateral slide 9, preventing further deformation of the mold due to displacement of the lateral slide 9 during the lateral extrusion process. During the leveling process, the holding assembly 6 holds the ends of the main body, providing stable support and restraint for the mold during the subsequent lateral and upward pressure shaping processes, avoiding damage to the mold due to excessive localized force. Furthermore, when the shaping block 23 applies upward force to the mold in step H, it does so while ensuring uniform force across the entire mold, reducing the occurrence of defects such as cracks caused by stress concentration.

[0086] like Figure 1-8 As shown, four guide seats 2 are provided on the base plate 1 at intervals. Three limiting columns 10 and two downward-pressing shaping assemblies 7 are provided on the first side of the shaping position 20 in the width direction. The limiting columns 10 are used to limit the main body 101 from moving away from the shaping position 20 in the first side direction. The limiting columns 10 and the downward-pressing shaping assemblies 7 are spaced apart. The downward-pressing shaping assembly 7 is located between two adjacent guide seats 2. The limiting columns 10 at both ends are located outside the guide seats 2 at the end portions, and the middle limiting column 10 is located between the two adjacent guide seats 2 in the middle. At the same time, five clamping assemblies 5 and five upper-side pressing shaping assemblies 8 are provided on the lateral slide 9. The clamping assemblies 5 and the upper-side pressing shaping assemblies 8 are staggered with the guide seats 2. The upper-side pressing shaping assembly 8 is located above the clamping assembly 5.

[0087] It should be noted that the guide seat 2, limiting posts 10, downward pressure shaping assembly 7, clamping assembly 5, and upper side pressure shaping assembly 8 preferably satisfy the following relationship, but this quantitative relationship is not limited to a specific number. Its main purpose is to maintain force balance and thus optimize the shaping effect. The specific quantitative relationship is as follows: N guide seats 2, where N is a natural number greater than 3, are configured with N / 2+1 limiting posts 10 and N / 2 downward pressure shaping assemblies 7, and the lateral slide 9 is configured with N+1 clamping assembly 5 and N+1 upper side pressure shaping assembly 8.

[0088] like Figure 2 As shown, the guide seat 2 is provided with a through transverse groove 22, the bottom of the shaping block 23 is connected to the lifting cylinder 24, and the top of the shaping block 23 is provided with a supporting ridge 230 that protrudes upward and extends along the width direction. When the supporting ridge 230 rises, it is exposed from the through transverse groove 22 and exceeds the support surface 21 of the guide seat 2.

[0089] More preferably, if Figure 4 As shown, the support ridge 230 includes a main ridge 231 and a flat support body 232 located below the main ridge 231. The flat support body 232 is thicker than the main ridge 231, and the main ridge 231 and the flat support body 232 are connected by a transition section with gradually increasing thickness. This structure ensures that the support ridge 230 has sufficient strength to withstand the forces during the leveling process while also adapting to the deformation requirements of different areas of the body 101. The flat support body 232 provides a relatively stable support base, while the main ridge 231 can more flexibly contact the raised areas of the body 101, achieving a precise shaping effect.

[0090] like Figure 4 As shown, the upper end of the main ridge 231 forms an upwardly raised arcuate surface 201. The arcuate surface 201 of the support ridge 230 forms a point-to-surface progressive contact with the raised area of ​​the body 101. This contact pattern effectively disperses pressure, avoiding excessive localized compressive stress and thus preventing damage to the body 101. Furthermore, the point-to-surface progressive contact better adapts to the shape of the raised area of ​​the body 101, providing more stable support and improving the accuracy and quality of leveling.

[0091] like Figure 1-3 As shown in Figures 9 and 10, the long pressing plate 3 has an upper pressing surface 301 and a first side pressing surface 302. The first side pressing surface 302 is used to press the lower side plate 103. The upper pressing surface 301 is lower than the support surface 21 of the guide seat 2. This prevents damage to the connection between the lower surface of the body 101 and the lower side plate 103.

[0092] like Figure 1-3As shown in Figures 9 and 10, the first side of the elongated pressing plate 3 is provided with spaced-apart notches 303, into which the supporting ridges 230 extend, thereby shaping the edge of the second side of the body 101 from bottom to top. This design expands the shaping range of the elongated pressing plate 3, enabling the equipment to effectively level more areas of the battery pack cooling module, improving the functionality and adaptability of the equipment and better meeting the shaping requirements of modules of different shapes and sizes.

[0093] like Figure 9 As shown, the clamping assembly 5 includes a clamping arm 51, a first drive cylinder 52, and a first rotating link 53. The distal end of the clamping arm 51 is rotatably connected to the output shaft of the first drive cylinder 52 extending toward the first side. One end of the first rotating link 53 is rotatably connected to the middle section of the clamping arm 51, and the other end is rotatably connected to a first connecting post extending horizontally toward the first side of the first drive cylinder 52. The clamping arm 51 is driven to rotate up and down, driving the elongated pressure plate 3 to move within a limited range along the guide rod 4 toward or away from the shaping station 20. Preferably, a first rotating link 53 is provided on both sides of the clamping arm 51 to ensure the stability of the clamping arm 51.

[0094] like Figure 9 As shown, the clamping arm 51 comprises an upper arm 501 and a lower arm 502. The extension lines of the upper and lower arms 501 and 502 are staggered, forming a first clearance portion 503 below the upper arm 501, recessed toward the lower arm 502. A second clearance portion 504 above the lower arm 502, recessed toward the upper arm 501, is also formed. The surface of the upper arm 501, which is adjacent to the lower arm 502 and faces the second side of the equipment after upward rotation, serves as a vertical active surface 505. The elongated pressing plate 3 is located within the first clearance portions 503 of the multiple clamping arms 51.

[0095] The lower end of the lower arm 502 is provided with an internal groove, forming two opposing first transfer ears 531. A first rotation axis 532 passes through the first transfer ears 531 and pivots with the output shaft of the first drive cylinder 52, enabling the clamping arm 51 to rotate up and down. The upper end of the lower arm 502 is provided with a transverse through-hole. Two first rotation links 53 are located on either side of the clamping arm 51 and are rotatably connected to the clamping arm 51 through the transverse through-hole. When the output shaft of the first drive cylinder 52 extends toward the first side of the device, the first rotation links 53 restrict the movement of the clamping arm 51 toward the first side, causing it to rotate. The clamping arm 51 is lifted, and the upper arm 501 presses against the elongated pressure plate 3. Conversely, when the output shaft of the first drive cylinder 52 retracts, the clamping arm 51 rotates downward and disengages from the elongated pressure plate 3.

[0096] Preferably, a first proximity sensor 54 is provided below the holding arm 51 . When the holding arm 51 contacts the first proximity sensor 54 , the first driving cylinder 52 stops moving, thereby protecting various components.

[0097] like Figure 10 As shown, the upper side pressure shaping assembly 8 includes a double-sided pressure block 81 having a lower pressure surface 801 and a second side pressure surface 802, a first connecting arm 82, a second drive cylinder 83, and a second rotating link 84. One end of the first connecting arm 82 is connected to the double-sided pressure block 81, and the other end is rotatably connected to the output shaft of the second drive cylinder 83 extending toward the first side. One end of the second rotating link 84 is rotatably connected to the middle section of the second connecting arm, and the other end is rotatably connected to the second connecting post extending horizontally toward the first side of the second drive cylinder 83. The upper side pressure shaping assembly 8 operates in a manner similar to that of the clamping assembly 5.

[0098] Preferably, a second proximity sensor 85 is provided above the upper side pressure shaping assembly 8. When the double-sided pressure block 81 or the first connecting arm 82 contacts the second proximity sensor 85, the second driving cylinder 83 stops moving, thereby protecting various components.

[0099] like Figure 9-10 As shown, when the lateral slide 9 approaches the shaping station 20, the clamping arm 51 is driven to rotate upward to the first side of the elongated pressing plate 3, thereby driving the elongated pressing plate 3 to move away from the shaping station 20. The upper pressing surface 301 supports the lower surface of the second side edge of the body 101 upward, and the first side pressing surface 302 is located on the first side of the lower side plate 103, pressing the lower side plate 103 toward the second side. The elongated pressing plate 3 and the clamping arm 51 cooperate to limit the movement of the lateral slide 9 away from the shaping station 20. The double-sided pressure block 81 is driven to rotate downward, and the second side pressing surface 802 is located on the first side of the upper side plate 102, pressing the upper side plate 102 toward the second side.

[0100] like Figure 9-10 As shown, the space formed between the upper pressing surface 301 and the lower pressing surface 801 becomes a restriction to limit the movement of the first side of the body 101, thereby being able to play a certain shaping and holding role. Especially when in the extreme position, the lower pressing surface 801 can contact the upper surface of the body 101.

[0101] like Figure 4As shown, the guide rod 4 includes a large diameter section 401, a small diameter section 402, and a limiting section 403. The large diameter section 401 is fixed to the elongated pressure plate 3, and the small diameter section 402 is provided with a guide connector 40 that can slide axially along the small diameter section 402. The guide connector 40 is provided with an external thread; the limiting section 403 restricts the guide connector 40 from disengaging from the guide rod 4, and the guide connector 40 is threadedly connected to the guide seat 2. Through this guide rod 4, the elongated pressure plate 3 achieves limited and fine-tuning movement. The entire guide rod 4 has a compact structural design, integrating the limiting, guiding, and fine-tuning functions into one. The large diameter section 401 is fixed to the elongated pressure plate 3, ensuring the firmness of the connection; the cooperation between the small diameter section 402 and the guide connector 40 realizes flexible guiding and fine-tuning functions; the design of the limiting section 403 prevents the guide connector 40 from falling off. This compact design helps to reduce the size and complexity of the equipment and improve the overall performance and reliability of the equipment.

[0102] like Figure 6 As shown, the downward shaping assembly 7 includes a downward shaping block 71, a third connecting arm 72, a third drive cylinder 734, and a third pivoting link 74. One end of the third connecting arm 72 is connected to the downward shaping block 71, and the other end is pivotally connected to the upwardly extending output shaft of the third drive cylinder 734. One end of the third pivoting link 74 is pivotally connected to the middle section of the third connecting arm 72, and the other end is pivotally connected to the third connecting post extending upwardly from the third drive cylinder 734. The upper side shaping assembly 8 operates in a similar manner to the upper side shaping assembly 8 and the clamping assembly 5.

[0103] like Figure 6 As shown, the holding assembly 6 includes a holding block 61, a fourth connecting arm 62, a fourth drive cylinder 63, and a fourth pivoting link 64. One end of the fourth connecting arm 62 is connected to the downward pressure shaping block 71, and the other end is pivotally connected to the upwardly extending output shaft of the fourth drive cylinder 63. One end of the fourth pivoting link 64 is pivotally connected to the middle section of the fourth connecting arm 62, and the other end is pivotally connected to the upwardly extending fourth connecting post of the fourth drive cylinder 63. The upper pressure shaping assembly 8 operates in a manner similar to that of the upper pressure shaping assembly 8, the downward pressure shaping assembly 7, and the clamping assembly 5.

[0104] like Figure 5 As shown, the lateral slide 9 comprises a vertical plate 91 and a support base 92 located on a second side of the vertical plate 91. The support base 92 comprises a plurality of spaced-apart triangular support walls 920, thereby enhancing structural strength. Below the support base 92 are multiple sliders that mate with the slide rails 90 on the base plate 1, ensuring smooth sliding of the lateral slide 9. The movement of the lateral slide 9 is driven by a cylinder 93.
