Description

Technical Field

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

[0002] Battery pack cooling pipes are key components for ensuring stable battery pack operating temperatures. Their ports require shaping to ensure sealing and assembly precision, preventing cooling medium leakage that could affect the battery pack's heat dissipation efficiency. In existing battery pack cooling pipe port shaping processes, the cooling pipes to be processed must first be stably clamped and fixed. However, traditional clamping devices often suffer from poor adaptability—they struggle to flexibly adjust the clamping structure according to the dimensions of different cooling pipe specifications, easily leading to pipe misalignment or uneven clamping force. Some devices lack targeted limiting and buffering designs, which may not only damage the cooling pipe surface during clamping but also affect the accuracy of port shaping due to axial movement or tilting of the cooling pipe during the shaping process, thereby increasing subsequent assembly difficulty and the risk of cooling system failure.

[0003] Therefore, those skilled in the art have provided a clamping and fixing device for shaping cooling pipe ports 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 clamping and fixing device for shaping cooling pipe ports.

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

[0006] A clamping and fixing device for shaping a cooling pipe port includes a base. A translation cylinder is fixedly installed on the top of the base in a horizontal direction. The output end of the translation cylinder is fixedly connected to the middle of the bottom end of a movable seat. The translation cylinder can drive the movable seat to perform translational movement along the width direction of the base. Support frames are fixedly connected to both sides of the top of the movable seat. Connecting arms are fixedly installed on the top of the two support frames in a horizontal direction. A pressure plate is fixedly connected to the end of the two connecting arms away from the support frames.

[0007] A lifting cylinder is fixedly installed at the bottom of the base. The output end of the lifting cylinder moves through the plate of the base and extends to the top of the base. The output end of the lifting cylinder is fixedly connected to the middle of the bottom of the support frame. A placement seat is fixedly connected to the top of the support frame. A cooling pipe to be processed is placed on the top of the placement seat, and a pressure plate can press and fix the cooling pipe to be processed.

[0008] Preferably, slide rails are symmetrically fixedly connected to both sides of the top of the base along the width direction of the base, and sliders are fixedly connected to both sides of the bottom of the movable seat corresponding to the slide rail positions, and the two sliders respectively form a sliding engagement with the slide rails on both sides.

[0009] Preferably, guide rods are vertically fixedly connected to the four corners of the bottom of the support frame, and guide sleeves are fixedly installed on the base corresponding to the position of each guide rod. The end of the guide rod away from the support frame slides through the corresponding guide sleeve.

[0010] Preferably, a shallow groove is provided at the top of the placement seat, the cooling pipe to be processed is placed inside the shallow groove, and a buffer pad is adhered to the bottom of the pressure plate.

[0011] Preferably, limiting components are installed at both ends of the placement base. The limiting components include guide seats, which are fixedly installed at the ends of the placement base. An elongated hole is formed in the middle of the guide seat along its length direction.

[0012] One end of the guide seat has a double-ended screw that extends through it. One end of the double-ended screw extends into the elongated hole and is rotatably connected to one end of the inner wall of the elongated hole. The two ends of the double-ended screw have external threads with opposite directions of rotation. T-blocks are threaded onto both ends of the double-ended screw. The bottom center of the T-block is slidably connected to the inner side of the elongated hole. The top of the T-block is connected to a support block by a screw. Limiting plates are fixedly connected to the two support blocks on opposite sides.

[0013] Preferably, both the limiting plate and the support block have a U-shaped structure with the opening facing downwards, and the limiting plate and the support block are together covered on the outside of the guide seat;

[0014] The top surface of the support block is flush with the bottom surface of the shallow groove, and the top height of the limiting plate is higher than the top height of the support block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This device uses a translation cylinder to drive the movable seat, which in turn moves the pressure plate horizontally, and a lifting cylinder to drive the support frame, which in turn adjusts the placement seat up and down. This allows for flexible adjustment of the relative position between the pressure plate and the cooling tube to be processed, adapting to the clamping requirements of cooling tubes of different specifications. The buffer pad at the bottom of the pressure plate can prevent the surface of the cooling tube from being damaged by rigid contact. Furthermore, by rotating the double-headed screw, the distance between the limiting plates can be adjusted to achieve lateral limitation of the cooling tube, preventing the cooling tube from moving during the shaping process. The overall structure ensures clamping stability and processing accuracy while protecting the cooling tube from damage, reducing the difficulty of subsequent assembly, and ensuring the heat dissipation reliability of the battery pack cooling system.

[0024] 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.

[0025] Reference Figure 1-5 A clamping and fixing device for shaping the port of a cooling pipe includes a base 1. A translation cylinder 3 is fixedly installed on the top of the base 1 in the horizontal direction. The output end of the translation cylinder 3 is fixedly connected to the middle of the bottom end of the movable seat 2. The translation cylinder 3 can drive the movable seat 2 to make translational movements in the width direction of the base 1. Support frames 4 are fixedly connected to both sides of the top of the movable seat 2. Connecting arms 5 are fixedly installed on the top of the two support frames 4 in the horizontal direction. A pressure plate 6 is fixedly connected to the end of the two connecting arms 5 away from the support frame 4.

[0026] A lifting cylinder 7 is fixedly installed at the bottom of the base 1. The output end of the lifting cylinder 7 moves through the plate of the base 1 and extends to the top of the base 1. The output end of the lifting cylinder 7 is fixedly connected to the middle of the bottom of the support frame 8. A placement seat 9 is fixedly connected to the top of the support frame 8. The cooling pipe 16 to be processed is placed on the top of the placement seat 9, and the pressure plate 6 can press and fix the cooling pipe 16 to be processed.

[0027] Using the above technical solution, the base 1 provides a stable support foundation. The translation cylinder 3 drives the movable seat 2 to move linearly along the width of the base 1, causing the pressure plate 6, connected by the support frame 4 and the connecting arm 5, to move synchronously. At the same time, the lifting cylinder 7 pushes the carrier frame 8 and the top placement seat 9 to adjust their height, so that the cooling tube 16 to be processed on the placement seat 9 can be accurately aligned with the pressure plate 6. Finally, the pressure plate 6 is used to press and fix the cooling tube 16 to be processed. This structure can flexibly adjust the relative position of the pressure plate 6 and the cooling tube 16 to be processed, adapting to the end shaping requirements of cooling tubes of different specifications. Moreover, the dual-cylinder drive design ensures stable and controllable clamping force, preventing displacement of the cooling tube during the shaping process, and effectively improving the accuracy and processing stability of the end shaping.

[0028] Slide rails 10 are symmetrically fixedly connected to the two sides of the top of the base 1 along the width direction of the base 1. Slide blocks 11 are fixedly connected to the two sides of the bottom of the movable seat 2 corresponding to the slide rails 10, and the two slide blocks 11 respectively form a sliding engagement with the slide rails 10 on both sides.

[0029] Using the above technical solution, the slide rail 10 symmetrically arranged at the top of the base 1 and the slider 11 at the bottom of the movable seat 2 form a sliding fit. This design provides precise guidance for the translational movement of the movable seat 2 and avoids the movable seat 2 from shifting or jamming under the drive of the translational cylinder 3.

[0030] Guide rods 12 are vertically fixedly connected at the four corners of the bottom of the support frame 8. Guide sleeves 13 are fixedly installed on the base 1 at the position corresponding to each guide rod 12. The end of the guide rod 12 away from the support frame 8 slides through the corresponding guide sleeve 13.

[0031] Using the above technical solution, the guide rods 12 at the four corners of the bottom of the support frame 8 slide and cooperate with the guide sleeves 13 on the base 1, which can provide precise guidance for the lifting of the support frame 8 and prevent it from tilting and swaying. This can ensure that the placement seat 9 and the cooling pipe 16 to be processed are kept horizontal, so that the pressure plate 6 has a uniform pressing force on the cooling pipe 16 to be processed, preventing the cooling pipe from deforming, and improving the stability and safety of lifting.

[0032] A shallow groove 14 is provided at the top of the placement seat 9, and the cooling pipe 16 to be processed is placed inside the shallow groove 14. A buffer pad 15 is glued to the bottom of the pressure plate 6.

[0033] Using the above technical solution, the shallow groove 14 at the top of the placement seat 9 is used to stably place the cooling tube 16 to be processed, providing a basic bearing space for the cooling tube; while the buffer pad 15 bonded to the bottom of the pressure plate 6 can play a buffering and pressure-reducing role when the pressure plate 6 presses the cooling tube 16 to be processed, which not only avoids the pressure plate 6 directly rigidly contacting the cooling tube and causing damage or deformation to the surface of the cooling tube, but also enhances the fit between the pressure plate 6 and the cooling tube through the flexible contact of the buffer pad 15, further improving the clamping and fixing effect, and adapting to the flexible clamping requirements of cooling tubes of different thicknesses.

[0034] Limiting components are installed at both ends of the placement base 9. The limiting components include guide seats 17, which are fixedly installed at the ends of the placement base 9. An elongated hole is provided in the middle of the guide seat 17 along its length.

[0035] One end of the guide seat 17 is movably connected to a double-ended screw 18. One end of the double-ended screw 18 extends into the elongated hole and is rotatably connected to one end of the inner wall of the elongated hole. The two ends of the double-ended screw 18 are provided with external threads in opposite directions. T-shaped blocks 19 are respectively threaded onto the two ends of the double-ended screw 18. The bottom middle of the T-shaped block 19 is slidably connected to the inner side of the elongated hole. The top of the T-shaped block 19 is connected to a support block 20 by a screw. Limiting plates 21 are fixedly connected to the two support blocks 20 on the opposite sides.

[0036] Using the above technical solution, the elongated hole of the guide seat 17 provides space for the sliding of the T-block 19. The two ends of the double-headed screw 18 have opposite external threads, which can drive the two T-blocks 19 to move towards or away from each other along the elongated hole when rotating, thereby adjusting the distance between the support block 20 and the limiting plate 21. This structure can flexibly adjust the relative position of the two limiting plates 21 according to the width of the cooling pipe 16 to be processed, thereby limiting the axial displacement of the cooling pipe 16 to be processed and preventing the cooling pipe from moving axially during the end shaping process.

[0037] Both the limiting plate 21 and the support block 20 have a U-shaped structure with the opening facing downwards, and the limiting plate 21 and the support block 20 are together covered on the outside of the guide seat 17.

[0038] The top surface of the support block 20 is flush with the bottom surface of the shallow groove 14, and the top height of the limiting plate 21 is higher than the top height of the support block 20.

[0039] Using the above technical solutions, both the limiting plate 21 and the support block 20 are U-shaped structures with their openings facing downwards. This structure can form a sliding guide relationship with the guide seat 17, improving the stability of the support block 20 when it moves along the elongated hole with the T-shaped block 19. The top of the support block 20 is flush with the shallow groove 14, which can ensure that the cooling tube 16 to be processed is placed horizontally. The top of the limiting plate 21 is even higher, which can firmly restrict the cooling tube from coming out laterally, improving the reliability of the device.

[0040] Working principle:

[0041] Start the lifting cylinder 7 at the bottom of the base 1 to drive the support frame 8 and the placement seat 9 to rise to the preset height, and place the cooling tube 16 to be processed into the shallow groove 14 of the placement seat 9. Depending on the width of the cooling tube 16 to be processed, rotate the double-headed screws 18 on the guide seats 17 at both ends of the placement seat 9, so that the double-headed screws 18 drive the two T-shaped blocks 19 to move towards or away from each other along the elongated hole, thereby adjusting the distance between the upper limit plates 21 of the support blocks 20 on both sides until the distance between the two limit plates 21 matches the width of the cooling tube, thus achieving the pre-limiting of the cooling tube. Then start the translation cylinder 3 at the top of the base 1 to drive the movable seat 2 to move, so that the movable seat 2 moves to the pressure plate 6 connected by the support frame 4 and the connecting arm 5 to the top of the cooling tube. Finally, start the lifting cylinder 7 again to push the support frame 8, the placement seat 9 and the cooling tube to rise further, so that the top of the cooling tube contacts and presses against the buffer pad 15 at the bottom of the pressure plate 6. After the clamping and fixing is completed, the shaping operation of the cooling tube port of the battery pack can be carried out.

[0042] 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.
