Description

Technical Field

[0001] This utility model relates to the technical field of cooling module processing, and in particular to a leveling device for cooling modules of aluminum die-cast battery packs. Background Technology

[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 overall vehicle performance 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 an aluminum die-cast upper shell plate) and an aluminum die-cast lower shell plate, with the shell plate exhibiting a relatively long and flat shape due to design requirements. In the manufacturing process, the aluminum alloy cover plate (or aluminum die-cast upper shell plate) and the aluminum die-cast lower shell plate are sealed together by friction welding to form a tight assembly, ensuring the battery pack's sealing performance and structural stability.

[0003] However, in actual production, the die-cast aluminum shell inevitably undergoes a certain degree of deformation after molding due to factors such as temperature changes and gravity. If this deformation is not effectively controlled, it will directly affect the subsequent assembly accuracy and product quality. Adding to the complexity, 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 deformation not only disrupts the flatness of the assembly but also causes dimensional accuracy to exceed tolerances, thus affecting the overall performance and reliability of the battery pack, posing a significant challenge to manufacturing.

[0004] To address the issue of structural component deformation, numerous explorations and practices have been undertaken within the industry. For instance, patent CN222790203U discloses a panel shaping device. This device, by incorporating components such as a lifting plate, shaping element, top plate, base, positioning element, and pressure cylinder, utilizes the cooperation between the curved surface of the shaping element and the protective cloth. Driven by the pressure cylinder, it flattens the injection-molded panel, effectively reducing the curvature of the finished panel. It boasts advantages such as simple structure, easy processing, and low cost, providing a feasible 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 moves the screw seat and clamping plate to achieve compression and limiting on both sides of the plywood, avoiding sliding and displacement of the plywood during shaping. At the same time, with the help of the rolling mechanism and the shaping mechanism, the unloading and shaping of the plywood are facilitated, which significantly improves the shaping quality of plywood and provides a useful reference for the shaping process of structural parts of different materials.

[0006] Patent CN119733777A discloses a side panel outer plate side pressing and shaping mold. Addressing the wrinkling problem on the negative angle flange side of the front windshield area of ​​new energy vehicle side panels, it cleverly employs a lower-positioned wedge mechanism, integrating a side pressing plate. Through a series of innovative designs, including a side-pressure nitrogen spring to counteract the lateral force of the main pressing plate, opposing shaping inserts to balance the side shaping load, and a conical balance block to ensure the working balance of the main pressing plate, it effectively solves the wrinkling problem during shaping. Furthermore, 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 outer shaping component, and an inner shaping component. The outer guide wheel of the outer shaping component is adjustable to the left and right along the reference plate. The inner guide wheel of the inner shaping component forms a guide channel with the outer guide wheel. It 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 flexible and adaptable design of structural component shaping devices.

[0008] Patent CN222739967U discloses a fixture structure for flat plate forming. Through the cooperation of a punch press, a base, a worktable, and sliding components, the flat plate is limited by the positioning component on the worktable. Then, the part of the flat plate to be formed is moved to the underside of the punch press shaft by the sliding component. This simplifies the forming steps, reduces manual operation, and improves the forming speed and forming quality, providing an effective solution for optimizing the forming process of flat plate structural parts.

[0009] While the aforementioned patents offer diverse technical means and innovative ideas for structural component shaping within their respective fields, they still have certain limitations when addressing the flatness and dimensional accuracy issues of aluminum die-cast battery pack cooling module assemblies caused by the forming deformation of the aluminum die-cast lower shell plate and the shrinkage deformation after friction welding. Existing technologies have not yet fully met the specific requirements for high-precision shaping of aluminum die-cast battery pack cooling module assemblies. Therefore, there is an urgent need to develop a highly 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.

[0025] The preferred technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the supporting ridge includes a main ridge and a flat supporting body located below the main ridge. The thickness of the flat supporting body is greater than the thickness of the main ridge.

[0026] The preferred technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the guide rod includes a large-diameter section, a small-diameter section and a limiting section. The large-diameter section is fixed to the long strip pressure plate. A guide connector that can slide along the axial direction of the small-diameter section is sleeved on the small-diameter section. The guide connector is provided with external threads. The limiting section restricts the guide connector from disengaging from the guide rod. The guide connector is threadedly connected to the guide seat.

[0031] Includes the following steps:

[0032] In the initial state, the clamping assembly is disengaged from the long strip pressure plate, and the lateral slide is moved away from the shaping position;

[0033] The upwardly deformed aluminum die-cast battery pack cooling module to be processed is placed into the shaping position formed by the guide seat, and the supporting surface of the guide seat supports the body upward.

[0034] The pressing and shaping component presses down on the first side of the body, and the pressing component presses down on both ends of the body;

[0037] The upper side pressing and shaping component is driven and presses the upper side plate toward the second side;

[0038] At the same time, the clamping component rotates downward to release the long strip pressure plate, the upper side pressing and shaping component moves upward away from the upper side plate, and the lower pressing and shaping component disengages from the body;

[0039] The rising of the shaping block applies an upward force to the body, causing the aluminum die-cast battery pack cooling module to be processed to deform upward.

[0040] The shaping blocks descend sequentially and are held for a period of time. The holding components are then released, and the aluminum die-cast battery pack cooling module to be processed returns to its free state. The body undergoes plastic deformation, thereby adjusting from a bent state to a horizontal state.

[0041] Compared with existing technologies, the advantages of this utility model are: it effectively solves the problem of upward bulging deformation of the cooling module in aluminum die-cast battery packs. The actions and steps of each component are automatically executed according to a certain logical sequence, reducing manual intervention, improving processing efficiency, and meeting the needs of large-scale production. Simultaneously, the orderly cooperation of each component avoids the risk of secondary deformation caused by human error or improper equipment operation during the module leveling process. In steps D and E, the clamping component restricts the movement of the lateral slide, preventing new deformation of the module due to lateral slide displacement during lateral extrusion. During leveling, the holding component holds both ends of the main body, providing stable support and constraint for the module during subsequent lateral and upward pressing and shaping processes, preventing damage to the module due to excessive local stress. Furthermore, when the shaping block applies an upward force to the module in step H, it ensures uniform stress distribution across the module, reducing defects such as cracks caused by stress concentration.

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

[0068] like Figure 1-2As shown, the leveling device includes a base plate 1 and spaced-apart guide seats 2, which together form a shaping position 20. The support surface 21 of the guide seats 2 is used to support the lower surface of the aluminum die-cast battery pack cooling module 100 to be processed. The multiple guide seats 2 form a rigid support matrix, and the support surface 21 is in contact with the lower surface of the module.

[0069] like Figure 1-4 As shown, the guide seat 2 has a vertically movable shaping block 23 in the middle, which rises to push the main body 101 upwards. Furthermore, the shaping position 20 has pressing components 6 on both sides to fix the main body 101, used to fix the two ends of the aluminum die-cast battery pack cooling module 100 to be processed and to level the ends. The pressing components 6 simultaneously press the two ends of the module, and fixing the two ends ensures that the shaping force is evenly transmitted along the length direction, forming a mechanical closed loop of fixed ends and shaped middle.

[0070] Furthermore, such as Figure 6 As shown, a plurality of pressing and shaping components 7 are provided on the first side of the shaping position 20 in the width direction. The pressing and 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 to level the side.

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

[0072] like Figure 1 , 3 As shown in Figure 8, 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 shaping assembly 8. The clamping assembly 5 drives the elongated pressure plate 3 to press the lower side plate 103 toward the second side and restrict the lateral slide 9 from moving away from the shaping position 20. The upper side-pressing shaping assembly 8 presses the upper side plate 102 toward the second side.

[0074] like Figure 1 , 3 As shown, a limiting post 10 is provided on the first side of the forming 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 the cooling module of an aluminum die-cast battery pack using this leveling equipment includes the following steps:

[0076] Step A: Initial state, the clamping component 5 is detached from the long strip pressure plate 3, and the side slide 9 is moved away from the shaping position 20.

[0077] Step B: Place the upward-bulging and deformed aluminum die-cast battery pack cooling module 100 into the shaping position 20 formed by the guide seat 2. The support surface 21 of the guide seat 2 supports the body 101 upwards. Specifically, as follows... Figure 6 As shown.

[0078] Step C: Press down the shaping component 7 to press down the first side of the body 101, and press the holding component 6 to press down both ends of the body.

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

[0080] Step E: The first side pressure surface 302 is located in the first side direction of the lower side plate 103 and presses the lower side plate 103 towards the second side direction, and the clamping component 5 restricts the lateral slide 9 from moving away from the shaping position 20.

[0081] Step F: The upper side pressing and shaping assembly 8 is driven and presses the upper side plate 102 towards the second side. Specifically, as follows... Figure 7 As shown.

[0082] Step G: At the same time, the clamping component 5 rotates downward to release the long strip pressure plate 3, the upper side pressing shaping component 8 moves upward away from the upper side plate 102, and the lower pressing shaping component 7 disengages from the 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. Specifically, as follows... Figure 8 As shown.

[0084] Step I: The shaping blocks 23 descend sequentially and are held for a period of time. The holding components 6 are released, and the aluminum die-cast battery pack cooling module 100 to be processed returns to a free state. The body 101 undergoes plastic deformation, thereby adjusting from a bent state to a horizontal state.

[0085] This leveling method effectively solves the problem of upward bulging deformation of the cooling module in aluminum die-cast battery packs. Through a series of orderly steps, such as the coordinated action of the downward pressing and shaping component 7 and the side pressing and shaping component, the bent module can be precisely 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 initial state setting in step A to the completion of the final return to the free state in step I, the actions and steps of each component are automatically executed in a certain logical sequence, reducing manual intervention, improving processing efficiency, and meeting the needs of large-scale production. The various steps are closely linked. The downward rotation of the clamping component 5 to release the long strip pressure plate 3, the upward movement of the upper side pressing and shaping component 8 away from the upper side plate 102, and the detachment of the downward pressing and shaping component 7 from the body 101 are almost simultaneous. This efficient coordinated action greatly shortens the cycle of the entire leveling operation. At the same time, the orderly cooperation of each component avoids the risk of secondary deformation caused by human error or improper equipment operation during the leveling process of the module. In steps D and E, the clamping component 5 restricts the movement of the lateral slide 9, preventing new deformation of the module due to displacement of the lateral slide 9 during lateral extrusion. During the leveling process, the pressing component 6 presses down on both ends of the main body, providing stable support and constraint for the module during subsequent lateral and upward pressing shaping processes, avoiding damage to the module due to excessive local stress. At the same time, when the shaping block 23 applies an upward force to the module in step H, it does so while ensuring uniform stress on the entire module, reducing the occurrence of defects such as cracks caused by stress concentration.

[0086] like Figure 1-8 As shown, the substrate 1 has four guide seats 2 spaced apart. The first side of the shaping position 20 in the width direction has three limiting posts 10 and two pressing shaping components 7. The limiting posts 10 are used to restrict the body 101 from moving away from the shaping position 20 in the first side direction. The limiting posts 10 and the pressing shaping components 7 are spaced apart. The pressing shaping components 7 are located between two adjacent guide seats 2. The limiting posts 10 at both ends are located outside the end guide seats 2, and the limiting post 10 in the middle is located between two adjacent guide seats 2 in the middle. Meanwhile, the lateral slide 9 has five clamping components 5 and five upper pressing shaping components 8, which are staggered from the guide seats 2. The upper pressing shaping components 8 are located above the clamping components 5.

[0087] It should be noted that the guide seat 2, limiting post 10, downward pressing shaping component 7, clamping component 5, and upper side pressing shaping component 8 preferably satisfy the following relationship, but such a quantitative relationship is not a limitation. Its main purpose is to maintain the balance of force, thereby optimizing 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 pressing shaping components 7, and N+1 clamping components 5 and N+1 upper side pressing shaping components 8 are configured on the side slide 9.

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

[0089] More preferably, such as Figure 4 As shown, the support ridge 230 includes a main ridge 231 and a flat support 232 located below the main ridge 231. The thickness of the flat support 232 is greater than the thickness of the main ridge 231, and the main ridge 231 and the flat support 232 are connected by a transition portion 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 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 is an upwardly convex arc surface 201. The arc surface 201 of the supporting ridge 230 forms a point-to-surface progressive contact with the convex area of ​​the body 101. This contact method can effectively disperse pressure and avoid excessive compressive stress in local areas, thereby preventing damage to the body 101. At the same time, the point-to-surface progressive contact can better adapt to the shape of the convex area of ​​the body 101, making the support more stable and improving the accuracy and quality of leveling.

[0091] like Figure 1-3 As shown in Figures 9 and 10, the elongated pressure plate 3 has an upper pressure surface 301 and a first side pressure surface 302. The first side pressure surface 302 is used to press down on the lower side plate 103. The upper pressure surface 301 is lower than the support surface 21 of the guide seat 2. This avoids 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 pressure plate 3 has spaced notches 303, into which the support ridge 230 extends, thereby enabling the edge of the second side of the body 101 to be shaped from bottom to top. This design expands the shaping range of the elongated pressure plate 3, allowing the equipment to effectively flatten more parts of the battery pack cooling module, improving the functionality and adaptability of the equipment, and better meeting the shaping needs 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 connecting rod 53. The end of the clamping arm 51 is rotatably connected to the output shaft of the first drive cylinder 52 extending to the first side. One end of the first rotating connecting rod 53 is rotatably connected to the middle section of the clamping arm 51, and the other end is rotatably connected to the first connecting post of the first drive cylinder 52 extending horizontally to the first side. The clamping arm 51 is driven to rotate up and down, causing the long strip pressure plate 3 to move along the guide rod 4 in a limited direction toward or away from the shaping position 20. Preferably, the clamping arm 51 is provided with the first rotating connecting rod 53 on both sides to ensure the stability of the clamping arm 51's movement.

[0094] like Figure 9 As shown, the clamping arm 51 includes an upper support arm 501 and a lower support arm 502. The extension lines of the upper support arm 501 and the lower support arm 502 are staggered, thereby forming a first recessed clearance portion 503 below the upper support arm 501 facing the lower support arm 502, and a second recessed clearance portion 504 above the lower support arm 502 facing the upper support arm 501. The side of the upper support arm 501 that is close to the lower support arm 502 and faces the second side of the equipment after being rotated upward is the working surface 505, which is a vertical surface. The elongated pressure plate 3 is located at the first clearance portion 503 of the plurality of clamping arms 51.

[0095] The lower support arm 502 has an inner groove at its lower end, forming two opposing first adapter ears 531. The first rotating shaft 532 passes through the first adapter ears 531 and is pivotally connected to the output shaft of the first drive cylinder 52, allowing the clamping arm 51 to rotate up and down. The upper end of the lower support arm 502 has a transverse through hole, and two first rotating connecting rods 53 are located on both sides of the clamping arm 51, respectively, 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 towards the first side of the equipment, the first rotating connecting rod 53 restricts the clamping arm 51 from moving towards the first side, causing it to rotate, the clamping arm 51 is raised, and the upper support arm 501 presses against the long strip 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 long strip pressure plate 3.

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

[0097] like Figure 10 As shown, the upper side-pressure shaping assembly 8 includes a double-sided pressure block 81 with 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 connecting rod 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 towards the first side. One end of the second rotating connecting rod 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 of the second drive cylinder 83 extending horizontally towards the first side. The movement of the upper side-pressure shaping assembly 8 is similar to that of the clamping assembly 5.

[0098] Preferably, a second proximity sensor 85 is provided above the upper side pressing and shaping component 8. When the double-sided pressing block 81 or the first connecting arm 82 contacts the second proximity sensor 85, the second drive cylinder 83 stops moving, thereby protecting each component.

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

[0100] like Figure 9-10 As shown, the space formed between the upper pressing surface 301 and the lower pressing surface 801 restricts the movement of the first side of the body 101, thereby playing a certain shaping and holding role. Especially 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. A guide connector 40, which can slide along the axial direction of the small-diameter section 402, is fitted onto the small-diameter section 402. The guide connector 40 has external threads. The limiting section 403 prevents the guide connector 40 from detaching from the guide rod 4. 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-tuned movement. The entire guide rod 4 has a compact structural design, integrating limiting, guiding, and fine-tuning functions. The large-diameter section 401 is fixed to the elongated pressure plate 3, ensuring a firm connection. The cooperation between the small-diameter section 402 and the guide connector 40 enables 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 reduce the size and complexity of the equipment, and improves 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 rotating connecting rod 74. One end of the third connecting arm 72 is connected to the downward shaping block 71, and the other end is rotatably connected to the output shaft extending upward from the third drive cylinder 734. One end of the third rotating connecting rod 74 is rotatably connected to the middle section of the third connecting arm 72, and the other end is rotatably connected to the third connecting post extending upward from the third drive cylinder 734. The movement of the upper side shaping assembly 8 is similar to that of the upper side shaping assembly 8 and the clamping assembly 5.

[0103] like Figure 6 As shown, the pressing assembly 6 includes a pressing block 61, a fourth connecting arm 62, a fourth drive cylinder 63, and a fourth rotating connecting rod 64. One end of the fourth connecting arm 62 is connected to the lower pressing and shaping block 71, and the other end is rotatably connected to the output shaft extending upward from the fourth drive cylinder 63. One end of the fourth rotating connecting rod 64 is rotatably connected to the middle section of the fourth connecting arm 62, and the other end is rotatably connected to the fourth connecting post extending upward from the fourth drive cylinder 63. The movement of the upper pressing and shaping assembly 8 is similar to that of the upper pressing and shaping assembly 8, the lower pressing and shaping assembly 7, and the clamping assembly 5.

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