Description
Technical Field
[0001] This utility model relates to the field of battery box fixing technology, and in particular to a clamp that facilitates fixing of battery boxes. Background Technology
[0002] Against the backdrop of the rapid development of the new energy battery industry, the battery box, as the core load-bearing and protective component of the battery pack, has increasingly stringent requirements for the fixation accuracy in its production, processing and performance testing. Whether it is the position calibration of wiring and welding, the pressure stability of sealing test, or the shape fixation of size calibration, the battery box needs to maintain a stable state of "no displacement and no flipping" during operation. Traditional clamps mostly rely on bidirectional cylinders or manual clamps to achieve horizontal clamping. While these can limit the lateral movement of the battery box to some extent, they lack effective countermeasures against common upward pushing forces and the risk of overturning in vibration environments. For example, in automated welding processes, the force of the welding torch can easily cause the battery box to shift upwards, leading to misalignment of the welding points. Although some improved clamps have attempted to add top pressure blocks or manual push rods, the former cannot adapt to battery boxes of different heights or with protruding structures, and is prone to losing its limiting effect due to height mismatch or structural interference. The latter is cumbersome to operate, has low fixing accuracy, and can only locally restrict vertical displacement, making it difficult to form all-round protection. Therefore, it is still impossible to meet the diverse and high-precision fixing requirements. Utility Model Content

[0013] 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.
[0014] Example: See Figures 1 to 4 This utility model discloses a clamp for securing a battery box, comprising a frame 1. Two limiting blocks are symmetrically fixed to the bottom of the frame 1, and each limiting block has a sliding groove 8. The sliding groove 8 ensures that the limiting frame 2 moves in a straight line without deviation, making the adjustment process smoother. Two limiting frames 2 are vertically slidably mounted on the frame 1. The limiting frames 2 allow for flexible adjustment of the spacing according to the size of the battery box, adapting to the fixing requirements of different specifications of battery boxes. Two moving blocks are fixed to the bottom of each of the two limiting frames 2, and the two moving blocks slide separately in the sliding groove 8. A linkage component is provided in the middle section of the bottom of the frame 1. Multiple friction pads 4 are equidistantly attached to the top surface of the frame 1. The friction pads 4 increase the friction coefficient between the box body 3 and the frame 1, and at the same time buffer the impact force when the box body 3 is placed, avoiding wear on the bottom of the box body 3. The box body 3 is placed in the middle section of the top of the frame 1, and two pairs of limiting components are provided on the two limiting frames 2 respectively.
[0015] In this utility model, an electric telescopic rod 6 is installed on one side of the bottom of the frame 1. A connecting block is fixedly connected to the output end of the electric telescopic rod 6. The connecting block is fixedly connected to one side of the bottom of one of the limiting frames 2 by bolts. The electric telescopic rod 6 facilitates precise control of the movement distance of the limiting frame 2 to meet the fixing requirements of battery boxes of different sizes. The linkage component includes a support shaft located in the middle of the bottom of the frame 1 and two second hinge blocks 7 respectively installed parallel to the bottom of the two limiting frames 2. A linkage plate 5 is rotatably provided at the bottom of the support shaft. Two first hinges are fixedly connected to both ends of the linkage plate 5. The two first hinge blocks are hinged with linkage rods, and the other ends of the two linkage rods are respectively hinged to the corresponding second hinge blocks 7. The linkage mechanism facilitates the synchronous movement of the two limiting frames 2, ensuring uniform clamping force on the box body 3. The limiting component includes an electric telescopic column 10 located at the top of the limiting frame 2. The output end of the electric telescopic column 10 is fixedly connected to a first mounting plate. A first threaded column is fixedly connected to the first mounting plate. A rotating plate 12 is rotatably sleeved on the first threaded column. A rotating notch is opened at the other end of the rotating plate 12, and a second threaded column is fixedly connected to the rotating notch. A positioning plate 13 is rotatably sleeved on the second threaded column. A limiting component allows for precise height adjustment of the positioning plate 13, ensuring accurate fit between the limiting notch 9 and the top of the box 3. Multiple fixing slots are equidistantly opened at one end of the rotating plate 12 and the first mounting plate. Each fixing slot contains a limiting protrusion for fixation. Multiple connecting slots are equidistantly opened on the rotating notch and the positioning plate 13. Positioning blocks for fixation are inserted into the connecting slots. A limiting notch 9 is opened at one bottom end of the positioning plate 13, and the limiting notch 9 movably abuts against one corner of the top of the box 3. The limiting notch 9 is designed to fit snugly against the top corner of the box 3, effectively limiting the vertical displacement and flipping tendency of the box 3. A first fixing nut 11 is screwed onto the first threaded post, with the bottom of the first fixing nut 11 abutting against the top of the rotating plate 12. A second fixing nut is screwed onto the second threaded post, with the bottom of the second fixing nut abutting against the top of the positioning plate 13. The first fixing nut 11 effectively fixes the angle of the rotating plate 12, ensuring no loosening after fixing. It is also easy to disassemble and adjust the angle of the rotating plate 12 as needed.
[0016] Working Principle: When using this utility model, firstly, connect each electrical component in this application to the power supply. Then, place the box 3 to be fixed in the middle of the top of the frame 1. The bottom of the box 3 is in close contact with the friction pad 4 on the top surface of the frame 1. The friction pad 4, made of a high-friction coefficient material, increases the friction between the box 3 and the frame 1, initially preventing the box 3 from sliding horizontally and laying the foundation for subsequent fixing. At this time, the two limiting frames 2 are in the initial open state, with a distance greater than the width of the box 3. The top limiting component is not in contact with the box 3. Then, activate the electric telescopic rod 6 on one side of the bottom of the frame 1: the output end of the electric telescopic rod 6 extends or retracts, driving the connected limiting frame 2 to move through the connecting block. The moving block at the bottom of the positioning frame 2 slides smoothly along the sliding groove 8 on the limiting block. Simultaneously, under the action of the linkage component: the second hinge block 7 at the bottom of the limiting frame 2 pulls the linkage plate 5 to rotate around the support shaft via the linkage rod. The linkage rod at the other end of the linkage plate 5 pushes the second hinge block 7 at the bottom of the other limiting frame 2, causing the other limiting frame 2 to move synchronously in the opposite direction along the sliding groove 8. The two limiting frames 2 move symmetrically closer or further apart about the center line of the frame 1, achieving precise adjustment of the spacing. When the inner side of the limiting frame 2 is in contact with both sides of the box body 3, the electric telescopic rod 6 stops moving, completing the bidirectional clamping of the box body 3 in the horizontal direction, ensuring no lateral displacement of the box body 3. Then, according to the height of the box body 3 and the shape of its top corners, the adjustment... Limiting components: Activate the electric telescopic column 10 to extend or retract its output end, driving the first mounting plate and the connected rotating plate 12 and positioning plate 13 to rise and fall until the limiting notch 9 at the bottom of the positioning plate 13 is at the same height as one corner of the top of the box 3. Simultaneously, rotate the rotating plate 12 around the first threaded column to adjust the horizontal angle of the positioning plate 13 so that the limiting notch 9 aligns with the top corner of the box 3. Then, rotate the positioning plate 13 around the second threaded column to finely adjust the angle, ensuring that the limiting notch 9 is tightly fitted with one corner of the top of the box 3. After adjustment, tighten the first fixing nut 11 and the second fixing nut. Through the cooperation of the fixing groove and the limiting protrusion, and the connecting groove and the positioning block, the angle of the rotating plate 12 and the positioning plate 13 is locked. To prevent loosening, four positioning plates 13 are positioned at the four corners of the top of the box 3. The limiting notches 9 fit against the corners of the box 3, restricting the box 3 from moving up and down and flipping. Together with the horizontal clamping, they form an all-round fixation. Finally, when the box 3 needs to be removed, first loosen the first fixing nut 11 and the second fixing nut, and rotate the rotating plate 12 and the positioning plate 13 in the opposite direction to make the limiting notches 9 disengage from the top of the box 3. Control the electric telescopic column 10 to retract, driving the positioning plate 13 to rise away from the box 3. Then, the electric telescopic rod 6 moves in the opposite direction, driving the two limiting frames 2 to open synchronously through the linkage component, releasing the horizontal clamping, and the box 3 can be removed. This concludes the use of the clamp that facilitates the fixing of the battery box.
