Description

Technical Field

[0001] This utility model relates to the field of battery pack cooling pipe processing technology, and in particular to a port shaping device for battery pack cooling pipes. Background Technology

[0002] Battery pack cooling pipes are core components of the thermal management system for new energy battery packs. They primarily circulate cooling media to remove heat generated during battery operation, ensuring stable operation of the battery pack within a suitable temperature range. Their ports require precise assembly with other pipes or connectors within the battery pack. Therefore, the dimensional accuracy, inner wall smoothness, and shape regularity of the ports directly affect the sealing performance and media flow efficiency of the cooling system. In existing cooling pipe processing technologies, after cutting and bending, the ports are prone to burrs, uneven inner walls, pipe deformation, or excessive ovality. Direct assembly may lead to cooling media leakage due to excessive assembly gaps, and pipe blockage due to port defects, thus affecting thermal management effectiveness. Furthermore, traditional port shaping equipment is mostly single-sided, making it difficult to achieve simultaneous shaping of both ports, resulting in poor coaxiality and low shaping consistency.

[0003] Therefore, those skilled in the art have provided a port shaping device for battery pack cooling pipes to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a port shaping device for battery pack cooling pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A port shaping device for a battery pack cooling tube includes a positioning clamp, on which the cooling tube to be shaped is detachably clamped, and at both ends of the positioning clamp are symmetrically provided shaping mechanisms for simultaneously shaping the two ends of the cooling tube to be shaped.

[0007] The shaping mechanism includes a double guide rail extending along the axis of the cooling tube to be shaped. A sliding base is slidably connected to the top of the double guide rail. A mounting base is vertically fixed to the top of the sliding base. A port shaping head is installed on the side of the mounting base near the cooling tube to be shaped.

[0008] The guide double rail is provided with a fixed frame at one end away from the positioning fixture. A servo thrust cylinder is fixedly installed on the upper side of the fixed frame away from the mounting base. The output end of the servo thrust cylinder is set along the axis of the cooling tube to be shaped, and is coaxially fixed to the side of the mounting base after moving through the fixed frame.

[0009] Preferably, the end of the port shaping head facing the cooling tube to be shaped has a shaping socket that matches the shape of the outer side of the end of the cooling tube to be shaped. The outer side of the shaping socket has a trumpet-shaped guide surface for guiding the end of the cooling tube to be shaped into place. The inner side of the shaping socket has a plurality of shaping blocks that match the shape of the inner wall of the end hole of the cooling tube to be shaped.

[0010] Preferably, a positioning plate is fixed to the end of the port shaping head away from the cooling tube to be shaped by screws, and L-shaped blocks are symmetrically fixed to both ends of the side of the mounting base. The vertical section of the L-shaped block is perpendicular to the side of the mounting base, and the horizontal sections of the two L-shaped blocks are arranged opposite to each other.

[0011] A support block is fixedly connected to the side of the mounting base at the lower position between the two L-shaped blocks. The positioning plate is inserted between the two L-shaped blocks, and the bottom end of the positioning plate is in contact with the top end of the support block.

[0012] Multiple mounting holes are provided between the positioning plate and the mounting base, and screws can be installed through the mounting holes to reinforce and fix the positioning plate.

[0013] Preferably, a pull rod type displacement gauge is fixedly installed on the side of the fixed frame away from the mounting base. The output end of the pull rod type displacement gauge is set along the axis of the cooling pipe to be shaped, and is fixedly connected to the middle of the bottom end of the sliding base after passing through the fixed frame.

[0014] Preferably, two sliders are fixed to both sides of the bottom end of the sliding base. The two sliders on the same side are spaced apart along the length of the double guide rails, and the sliders on both sides form a sliding fit with the rails on both sides of the double guide rails.

[0015] Preferably, both sides of the port shaping head are provided with air blowing holes that communicate with the internal shaping sockets, and air blowing connectors are fixedly connected to the positions of the air blowing holes on both sides of the port shaping head. The air blowing connectors are used to connect to an external high-pressure air source.

[0016] A suction pipe is installed through the lower side of the mounting base. A suction hood is fixed to one end of the suction pipe near the port shaping head. The suction hood is located directly below the end of the port shaping head facing the cooling pipe to be shaped in the vertical direction, and its opening faces upward.

[0017] Preferably, a fault-proofing camera is mounted on the top of the mounting base of one of the shaping mechanisms via an adjustable bracket, and the lens barrel of the fault-proofing camera is angled toward the end of the cooling pipe to be shaped.

[0019] This device uses a positioning fixture to stably clamp the cooling tube to be shaped. With the symmetrically arranged shaping mechanism and servo thrust cylinder at both ends, it can drive the port shaping head to simultaneously perform shaping operations on both ends of the cooling tube to be shaped, effectively improving the coaxiality and shaping consistency of the two ends.

[0020] The port shaping head is detachably connected to the mounting base via a positioning plate, making it easy to replace the appropriate port shaping head according to different specifications of cooling tubes to be shaped, greatly improving the device's compatibility with multiple models of cooling tubes; and the shaping socket on the port shaping head works in conjunction with the inner shaping block to simultaneously correct deformation on the outer side of the port and burrs on the inner wall, ensuring port dimensional accuracy, inner wall smoothness and shape regularity, meeting the requirements for precise assembly with other pipes or connectors in the battery pack.

[0021] Meanwhile, the air blowing connector of the port shaping head and the dust suction cover of the mounting base work together to remove impurities generated during the shaping process in a timely manner, avoiding impurities from affecting the shaping accuracy or causing port contamination.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-4 A port shaping device for a battery pack cooling pipe includes a positioning clamp 1, on which a cooling pipe 2 to be shaped is detachably clamped, and at both ends of the positioning clamp 1 are symmetrically provided shaping mechanisms for simultaneously shaping the two ports of the cooling pipe 2 to be shaped.

[0030] The shaping mechanism includes a double guide rail 3 extending along the axis of the cooling pipe 2 to be shaped. A sliding base 4 is slidably connected to the top of the double guide rail 3. A mounting base 5 is vertically fixed to the top of the sliding base 4. A port shaping head 6 is installed on the side of the mounting base 5 near the cooling pipe 2 to be shaped.

[0031] A fixed frame 7 is provided at the end of the guide double rail 3 away from the positioning fixture 1. A servo thrust cylinder 8 is fixedly installed on the upper side of the fixed frame 7 away from the mounting base 5. The output end of the servo thrust cylinder 8 is set along the axis of the cooling pipe 2 to be shaped, and is coaxially fixed to the side of the mounting base 5 after passing through the fixed frame 7.

[0032] Using the above technical solution, the symmetrically arranged shaping mechanisms at both ends of the positioning fixture 1, together with the guide double rails 3 extending along the axis of the cooling pipe 2 to be shaped, provide precise sliding guidance for the sliding base 4, ensuring that the sliding base 4 drives the mounting base 5 and the port shaping head 6 to move smoothly; the output end of the servo thrust cylinder 8 installed on the fixed frame 7 is coaxially fixed to the mounting base 5, and can output stable thrust along the axis of the cooling pipe, driving the port shaping heads 6 at both ends to simultaneously perform shaping operations on the two ends of the cooling pipe 2 to be shaped, which not only improves the shaping efficiency, but also ensures the shaping consistency of the two ends of the cooling pipe through symmetrical synchronous operation.

[0033] The end of the shaping head 6 facing the cooling tube 2 to be shaped is provided with a shaping port 61 that matches the shape of the outer side of the end of the cooling tube 2 to be shaped. The outer side of the shaping port 61 is provided with a trumpet-shaped guide surface for guiding the end of the cooling tube 2 to be shaped into place. The inner side of the shaping port 61 is provided with a plurality of shaping blocks 62 that match the shape of the inner wall of the end hole of the cooling tube 2 to be shaped.

[0034] Using the above technical solution, the shaping socket 61 at the end of the port shaping head 6 is adapted to the shape of the outer side of the end of the cooling tube 2 to be shaped, which can accurately shape the outer side of the cooling tube port and avoid uneven deformation of the outer wall of the port; the flared guide surface on the outward side of the shaping socket 61 can guide the end of the cooling tube 2 to be shaped to be smoothly inserted into the shaping socket 61 when the port shaping head 6 approaches the cooling tube, reducing the collision and wear between the end and the socket; the multiple shaping blocks 62 on the inner side of the shaping socket 61 are adapted to the shape of the inner wall of the end hole of the cooling tube 2 to be shaped, which can simultaneously shape the inner wall of the end hole of the cooling tube, correct defects such as burrs and unevenness of the inner wall, ensure the dimensional accuracy of the end hole of the cooling tube, and meet the subsequent assembly requirements of the cooling tube and other components.

[0035] A positioning plate 63 is fixed to the end of the port shaping head 6 away from the cooling tube 2 to be shaped by screws. L-shaped blocks 9 are symmetrically fixed to both ends of the side of the mounting base 5. The vertical section of the L-shaped block 9 is perpendicular to the side of the mounting base 5, and the horizontal sections of the two L-shaped blocks 9 are set opposite to each other.

[0036] A support block 10 is fixedly connected to the side of the mounting base 5 at the lower position between the two L-shaped blocks 9. The positioning plate 63 is inserted between the two L-shaped blocks 9, and the bottom end of the positioning plate 63 is in contact with the top end of the support block 10.

[0037] Multiple mounting holes 11 are provided between the positioning plate 63 and the mounting base 5, and screws can be installed through the mounting holes 11 to reinforce and fix the positioning plate 63.

[0038] By adopting the above technical solution, the L-shaped stop 9 horizontally limits the positioning plate 63 and the support block 10 vertically supports the positioning plate 63, ensuring that the port shaping head 6 is installed in a precise position and has a horizontal posture, avoiding shaping deviation caused by installation offset; the positioning plate 63 and the mounting base 5 are reinforced and fixed by screws through the mounting hole 11, ensuring that the port shaping head 6 is stable and does not loosen during operation, and the detachable structure makes it easy to replace shaping heads of different specifications, improving the versatility of the device.

[0039] A tie rod type displacement gauge 12 is fixedly installed on the side of the fixed frame away from the mounting base 5. The output end of the tie rod type displacement gauge 12 is set along the axis of the cooling pipe 2 to be shaped, and it moves through the fixed frame 7 and is fixedly connected to the middle of the bottom of the sliding base 4.

[0040] Using the above technical solution, the pull rod displacement gauge 12 can detect the sliding displacement of the sliding base 4 in real time, and then accurately feed back the shaping stroke of the port shaping head 6 to be shaped at the port of the cooling tube 2; the operator can use the detection data of the pull rod displacement gauge 12 to accurately control the thrust output and stroke of the servo thrust cylinder 8.

[0041] Two sliders 13 are fixed to both sides of the bottom of the sliding base 4. The two sliders 13 on the same side are spaced apart along the length of the guide double rail 3, and the sliders 13 on both sides form a sliding fit with the rails on both sides of the guide double rail 3 respectively.

[0042] By adopting the above technical solution, the slider 13 can strictly limit the lateral displacement of the sliding base 4, ensuring that the sliding base 4 slides smoothly only along the axis of the guide double rail 3, avoiding jamming and shaking during the sliding process, thereby ensuring that the shaping action of the port shaping head 6 on the port of the cooling pipe 2 to be shaped is accurate and stable.

[0043] Both sides of the port shaping head 6 are provided with air blowing holes that communicate with the internal shaping socket 61, and air blowing connectors 14 are fixedly connected to the corresponding air blowing hole positions on both sides of the port shaping head 6. The air blowing connectors 14 are used to connect to an external high-pressure air source.

[0044] A suction pipe 15 is installed through the lower side of the mounting base 5. A suction hood 16 is fixed to one end of the suction pipe 15 near the port shaping head 6. The suction hood 16 is located directly below the end of the port shaping head 6 facing the cooling pipe 2 to be shaped in the vertical direction, and its opening is set upward.

[0045] By adopting the above technical solution, the air blowing holes on both sides of the port shaping head 6 cooperate with the air blowing connector 14. After connecting to an external high-pressure air source, high-pressure airflow can be blown into the shaping port 61 to promptly blow out metal chips, dust and other impurities generated during the shaping process from the shaping port 61. This prevents impurities from adhering to the inner wall of the shaping port 61 or the port of the cooling tube 2 to be shaped, thus preventing impurities from affecting the shaping accuracy or causing secondary pollution of the port. The dust suction pipe 15 on the side of the mounting base 5 cooperates with the dust suction hood 16. The dust suction hood 16 is located directly below the end of the port shaping head 6 facing the cooling tube 2 to be shaped. It can efficiently collect impurities carried out by the airflow. The impurities are sucked into the dust suction pipe 15 and discharged through the external negative pressure dust suction system, realizing centralized treatment of impurities. This not only keeps the shaping working environment clean, but also prevents impurities from entering the gaps between the internal components of the device, reducing component wear and extending the overall service life of the device.

[0046] One of the shaping mechanisms has a mounting base 5 with an adjustable bracket at the top to mount a fault-proof camera 17. The lens barrel of the fault-proof camera 17 is angled toward the end of the cooling pipe 2 to be shaped.

[0047] Using the above technical solution, the error-proof camera 17 can detect the installation direction of the cooling tube 2 to be shaped and determine whether there is a problem with reverse installation of the cooling tube; if reverse installation of the cooling tube is detected, timely feedback can be given to prevent the shaping scrap caused by the incorrect installation direction of the cooling tube, and ensure the effectiveness of the port shaping operation and the product qualification rate.

[0048] Working principle:

[0049] First, the cooling tube 2 to be shaped is clamped and fixed by the positioning fixture 1, while the error-proof camera 17 detects the installation direction of the cooling tube to avoid reverse installation. Then, the servo thrust cylinder 8 on the fixing frame 7 is activated, pushing the mounting base 5 along the axis of the cooling tube 2 to be shaped, which drives the sliding base 4 to slide smoothly along the guide double rail 3, so that the port shaping head 6 on the mounting base 5 is close to the port of the cooling tube. The shaping socket 61 of the port shaping head 6 fits the end of the cooling tube under the guidance of the trumpet-shaped guide surface. The shaping socket 61 shapes the outer side of the port and the inner shaping block 62 corrects the inner wall of the end hole. The pull rod displacement gauge 12 detects the displacement of the sliding base 4 in real time to control the shaping stroke. During the shaping, the air blowing connector 14 is connected to the high-pressure air source, and the impurities in the shaping socket 61 are blown out through the air blowing hole. The dust suction hood 16 below works with the dust suction pipe 15 to collect the impurities, and finally the synchronous and precise shaping of the two ends of the cooling tube is completed.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
