Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and more specifically, to a sheet forming fixture. Background Technology

[0002] Battery packs are key metal components inside batteries used for electrode leads, current conduction, or cell encapsulation. The core material varies depending on the battery type. Lithium-ion batteries commonly use pure copper or nickel-plated copper sheets, while lead-acid batteries often use lead alloy sheets. Their structure must precisely match the cell tabs, casing, or terminals. They are typically designed as sheet-like structures with positioning holes and bent edges, ensuring stable current conduction while also providing cell fixation and short-circuit protection. This directly affects the battery's conductivity and safety performance. During welding, battery packs require shaping and clamping. First, tooling fixtures are used to precisely position the packs against the components to be welded, ensuring a tight fit between the contact surfaces. This facilitates subsequent processing. Since different sizes of battery packs require different shaping ranges, clamping adjustments are necessary.

[0003] In related technologies, during the use of shaping fixtures, workers typically move a stack of sheet metal pieces into the fixture. The fixture uses restrictive forces on both sides to hold the sheet metal pieces at a specific temperature, allowing workers to perform subsequent processing operations on the sheet metal for use.

[0004] However, in the current use of shaping fixtures, the fixed-size fixtures can only clamp a single type of sheet, making it difficult for the fixtures to perform shaping and clamping operations on the sheet according to the clamping requirements of the workpiece, thus affecting the flexibility and adaptability of the shaping fixtures.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figures 1-4This utility model provides a technical solution: a piece-forming fixture, including a base 1 and a clamping adjustment mechanism. A support 2 is fixedly connected to the top of the base 1, and a fixing plate 3 is fixedly connected to the right side of the top of the base 1. The clamping adjustment operation can be performed according to the actual size of the external piece-forming fixture and the required clamping range, so that users can perform shaping and clamping operations on different types of piece-forming workpieces. This avoids the situation where it is difficult to perform adaptive clamping during piece-forming processing, thus improving the flexibility and adaptability of the support 2 and the fixing plate 3.

[0021] Reference Figures 1-4 In a preferred embodiment, the clamping and adjusting mechanism includes an adjusting plate 4, which is movably connected to the top of the support 2. A clamping plate 5 is movably connected to the right side of the adjusting plate 4. A side frame 6 is fixedly connected to the rear side of the top of the base 1. A screw hole 7 is opened on the left side of the adjusting plate 4, and a stud 8 connected to the clamping plate 5 is threaded inside the screw hole 7. The adjusting and positioning mechanism is set on both sides of the top of the adjusting plate 4. The outer packaging piece that needs to be shaped and clamped is moved to the left side of the fixed plate 3, and the rear side of the packaging piece contacts the front side of the side frame 6, so that the packaging piece is neatly placed on the top of the support 2. Then, the stud 8 is held and rotated to engage the screw hole 7, applying a rightward threaded thrust to the clamping plate 5. The clamping plate 5, in conjunction with the fixing plate 3, clamps the package piece to maintain its temperature. The positioning mechanism includes a positioning cavity 9, a positioning frame 10, and a positioning hole 11. The positioning cavity 9 is located on both sides of the top of the adjusting plate 4. The positioning frame 10 is movably connected inside the positioning cavity 9. The positioning hole 11 is located on both sides of the top of the base 1. The bottom of the positioning frame 10 is located inside the positioning hole 11. This allows for the adjustment and positioning of the adjusting plate 4 and the base 1, enabling users to adjust and position the adjusting plate 4 and the base 1 according to their actual needs. This avoids situations where the adjusting plate 4 is difficult to adjust during use, thus improving the ease of adjustment of the adjusting plate 4.

[0022] Reference Figures 2-3 In a preferred embodiment, by providing a translation slot 12 at the bottom of the adjusting plate 4, the support 2 extends through the translation slot 12 to the left side of the adjusting plate 4. This allows the support 2 to move through the translation space of the adjusting plate 4, preventing the support 2 from obstructing the adjusting plate 4 during use and making it difficult for the adjusting plate 4 to be effectively translated. This improves the smoothness of the adjustment of the adjusting plate 4. Both sides of the support 2 have connection slots 13 on their left sides. A connecting strip 14 is movably connected inside the connection slot 13. The outer side of the connecting strip 14 is fixedly connected to the inner wall of the translation slot 12. This allows for translational connection between the support 2 and the adjusting plate 4 to prevent offset, avoiding vertical movement or offset during use. This improves the adjustment stability of the adjusting plate 4.

[0023] Reference Figures 2-4In a preferred embodiment, a support opening 15 is provided on the left side of the rear side of the side frame 6. A support frame 16 is movably connected inside the support opening 15. The front side of the support frame 16 is fixedly connected to the rear side of the clamping plate 5, which can provide translational support between the clamping plate 5 and the side frame 6, preventing the clamping plate 5 from rotating or shifting during use, thus improving the working stability of the clamping plate 5. A reinforcing plate 17 is connected to the rear side of the support frame 16 by bolts and threads. The front side of the reinforcing plate 17 contacts the rear side of the side frame 6, which can provide support and reinforcement between the support frame 16 and the side frame 6, preventing the support frame 16 from being unable to effectively provide translational support for the clamping plate 5 during use, thus improving the support effect of the support frame 16.

[0024] Reference Figures 2-4 In a preferred embodiment, connecting cylinders 18 are fixedly connected to both sides of the left side of the clamping plate 5. Connecting seats 19 are movably connected inside the connecting cylinders 18. The left side of the connecting seat 19 is fixedly connected to the right side of the stud 8. This allows for a rotatable connection between the stud 8 and the clamping plate 5 to prevent displacement, thus avoiding separation of the stud 8 from the clamping plate 5 during use. This improves the connection effect between the stud 8 and the clamping plate 5. A receiving groove 20 is provided on the right side of the adjusting plate 4. The left side of the receiving groove 20 is connected to the right side of the screw hole 7. The receiving groove 20 matches the connecting cylinder 18 and provides space for the connecting cylinder 18 to move to the left, thus improving the mobility of the connecting cylinder 18.

[0025] Furthermore, positioning holes 11 are provided every 10mm along the length of the base, totaling 20-30 holes, to accommodate clasps of 50-300mm in size; the hole diameter is 8mm, the positioning bracket diameter is 7.8mm, and the fitting clearance is 0.2mm to prevent loosening. The top of the positioning bracket 10 is equipped with a push-button spring latch; after being inserted into the positioning hole 11, the latch pops out and locks against the hole wall, preventing it from easily dislodging under vibration or impact; the positioning bracket 10 is made of 45# steel with a galvanized surface for rust prevention.

[0026] Furthermore, a miniature deep groove ball bearing (model 608) is installed inside the connecting cylinder 18. The connecting seat 19 is interference-fitted with the inner ring of the bearing to achieve a rotational connection and reduce frictional resistance. An annular protrusion (12mm in diameter) is provided on the right end of the connecting seat 19 to prevent it from coming out of the connecting cylinder. The receiving groove 20 is 20mm deep, the connecting cylinder is 18mm long, and a 2mm movement allowance is reserved to ensure that the connecting cylinder can move smoothly and meet the maximum clamping stroke of the clamping plate.

[0027] Furthermore, two positioning pins (5mm in diameter and 3mm in height) are added to the front side of the side frame and the left side of the fixing plate, which are adapted to the pre-set positioning holes of the wrapping piece to achieve precise positioning for irregular and asymmetrical wrapping pieces; the perpendicularity error between the side frame and the fixing plate is ≤0.03mm / m, ensuring accurate positioning reference. Thickness adjustment shims (0.5mm, 1mm, and 2mm) are provided at the bottom of the clamping plate. By adding or removing shims, the distance between the clamping plate and the top of the support can be adjusted to accommodate wrapping pieces with a thickness of 0.3-5mm, avoiding clamping that is too loose or too tight.

[0028] Specifically, the working process or principle of this piece-forming fixture is as follows: During use, based on the actual clamping range required for the external piece, the hand-held positioning frame 10 is moved upwards to disengage from the positioning hole 11. Then, the hand-held adjusting plate 4 is moved to the right, allowing for a translational adjustment of the position of the adjusting plate 4 and changing the subsequent clamping range of the clamping plate 5. At this time, the support 2 moves inside the translational opening 12, and simultaneously, the connecting strip 14 moves with the adjusting plate 4 inside the connecting opening 13, performing a translational connection between the adjusting plate 4 and the support 2 to prevent displacement. During this process, the stud 8, in conjunction with the screw hole 7, drives the clamping plate 5 to move with the adjusting plate 4. Meanwhile, the support frame 16 moves with the clamping plate 5 inside the support opening 15, cooperating with the reinforcing plate 17 to perform a translational connection between the clamping plate 5 and the side frame 6 to support anti-displacement work. After the adjusting plate 4 is adjusted, the hand-held positioning frame 10 is moved downwards and inserted into the positioning hole 11, allowing the positioning frame 10 to cooperate with the connecting strip 14. The adjustment plate 4 and the base 1 are positioned by inserting and connecting through the positioning hole 11 and the connection port 13. Then, the external wrapping piece is moved and placed on the top of the support 2, so that the right side of the wrapping piece contacts the fixing plate 3 and the rear side of the wrapping piece contacts the front side of the side frame 6. This allows the wrapping piece to be placed on the top of the support 2. After the wrapping piece is shaped and aligned, the stud 8 is rotated to engage with the screw hole 7, applying a threaded thrust to the right side of the clamping plate 5. At this time, the connecting seat 19 moves with the stud 8 inside the connecting cylinder 18, performing a rotational connection between the stud 8 and the clamping plate 5 to prevent separation. At the same time, the support frame 16 moves with the clamping plate 5 inside the support port 15, and drives the reinforcing plate 17 to move behind the side frame 6, providing translational support to the clamping plate 5 during the movement to prevent displacement. The stud 8 engages with the screw hole 7 to push the clamping plate 5 to contact the wrapping piece and engage with the fixing plate 3, clamping the wrapping piece to allow the user to perform subsequent processing operations.
