The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a welding fixture for vehicle manufacturing, such as... Figure 1-4As shown, the welding fixture for vehicle manufacturing includes: multiple support legs 1, each with an extension leg 2 slidably mounted inside; a placement platform 3 for placing the vehicle body, the placement platform 3 being fixedly mounted on the top of the extension leg 2; two limiting plates 4 for fixing the vehicle body, both limiting plates 4 being slidably mounted inside the placement platform 3 and slidingly fitting against the inner wall of the placement platform 3, the tops of both limiting plates 4 extending outside the placement platform 3; multiple clamping mechanisms, all located on the limiting plates 4, for further clamping and fixing the vehicle body frame; and multiple adjusting mechanisms, all located on the limiting plates 4, for adjusting the position of the clamping mechanisms.

[0023] In this embodiment, the support leg 1 serves as the basic support structure of the clamp. The extension leg 2 is slidably installed inside the support leg 1, and its height can be adjusted as needed to increase the flexibility and applicability of the clamp. The placement platform 3 is fixedly installed on the top of the extension leg 2 to place the car body to be welded, providing a stable operating platform for welding operations. Both limiting plates 4 are slidably installed inside the placement platform 3 and slide against its inner wall. The limiting plates 4 can be adjusted according to the width of the car body to ensure the stability and accuracy of the car body on the placement platform 3. Multiple clamping mechanisms are provided on the limiting plates 4 to further clamp and fix the car body frame, ensuring the stability and accuracy of the frame during the welding process and avoiding welding quality problems caused by frame shaking. Multiple adjustment mechanisms are provided on the limiting plates 4 to adjust the position of the clamping mechanisms, allowing the clamping mechanisms to be adjusted according to the frame shape and size of different car models, further improving the flexibility and adaptability of the clamp.

[0024] In a further preferred embodiment of this utility model, the clamping mechanism includes a mounting frame 5, a first bidirectional motor 6, a first bidirectional screw 7, and two clamping blocks 8. The mounting frame 5 is slidably mounted on the limiting plate 4. The first bidirectional motor 6 is fixedly mounted on one side of the mounting frame 5. The first bidirectional screw 7 is rotatably mounted on the mounting frame 5. One end of the first bidirectional screw 7 is fixed to the output shaft of the first bidirectional motor 6. The two clamping blocks 8 are threadedly mounted on the first bidirectional screw 7, and the two clamping blocks 8 are slidably fitted with the mounting frame 5.

[0025] In this embodiment, the mounting frame 5 serves as the support structure for the clamping mechanism. The mounting frame 5 is slidably mounted on the limiting plate 4. The first bidirectional motor 6 is fixedly mounted on one side of the mounting frame 5 to provide power for the rotation of the first bidirectional screw 7. The first bidirectional screw 7 is rotatably mounted on the mounting frame 5, with one end fixed to the output shaft of the first bidirectional motor 6. The rotation of the first bidirectional screw 7 will drive the two clamping blocks 8 to move synchronously towards or away from each other, thereby clamping or releasing the frame. When it is necessary to clamp the frame, the first bidirectional motor 6 is started to drive the first bidirectional screw 7 to rotate. Since both clamping blocks 8 are threaded onto the first bidirectional screw 7, as the screw rotates, the two clamping blocks 8 will move synchronously towards each other until they are tightly attached to the surface of the frame, thereby achieving a stable clamping of the frame.

[0026] In a further preferred embodiment of this utility model, the adjusting mechanism includes a threaded cylinder 9, a threaded rod 10, a drive motor 11, a drive gear 12, and a plurality of teeth 13. The threaded cylinder 9 is rotatably mounted on the limiting plate 4, the threaded rod 10 is threadedly mounted on the threaded cylinder 9, one end of the threaded rod 10 is fixed to the mounting bracket 5, the drive motor 11 is fixedly mounted on the limiting plate 4, the drive gear 12 is fixedly mounted on the output shaft of the drive motor 11, and the plurality of teeth 13 are all provided on the threaded cylinder 9 and mesh with the drive gear 12.

[0027] In this embodiment, the threaded cylinder 9 is rotatably mounted on the limiting plate 4, serving as a support and transmission component for the threaded rod 10. The threaded rod 10 is threaded onto the threaded cylinder 9, with one end fixed to the mounting frame 5. As the threaded cylinder 9 rotates, the threaded rod 10 moves axially, thereby driving the mounting frame 5 and its clamping mechanism to adjust their positions. The drive motor 11 is fixedly mounted on the limiting plate 4, providing power for the rotation of the drive gear 12. The drive gear 12 is fixedly mounted on the output shaft of the drive motor 11, and rotates the threaded cylinder 9 by meshing with the teeth 13 on the threaded cylinder 9. Multiple teeth 13 are provided on the threaded cylinder 9 and mesh with the drive gear 12, ensuring that the drive gear 12 can stably drive the threaded cylinder 9 to rotate. The adjustment mechanism allows the clamping mechanism to be adjusted more precisely according to the specific shape and size of the frame, further improving the flexibility and adaptability of the clamp.

[0028] In a further preferred embodiment of the present invention, a second bidirectional motor 14 is fixedly installed on one side of the placement platform 3, and a second bidirectional screw 15 is rotatably installed inside the placement platform 3. One end of the second bidirectional screw 15 extends to the outside of the placement platform 3 and is fixed to the output shaft of the second bidirectional motor 14. The second bidirectional screw 15 is threaded through the two limiting plates 4.

[0029] In this embodiment, the second bidirectional motor 14 is fixedly installed on one side of the placement platform 3 to provide power for the rotation of the second bidirectional screw 15. The second bidirectional screw 15 is rotatably installed inside the placement platform 3, with one end extending outside the placement platform 3 and fixed to the output shaft of the second bidirectional motor 14. The rotation of the second bidirectional screw 15 will drive the two limiting plates 4 to move synchronously towards or away from each other, so as to adapt to frames of different widths. Through the design of the second bidirectional motor 14 and the second bidirectional screw 15, the position of the limiting plates 4 can be quickly and accurately adjusted, further improving the flexibility and adaptability of the fixture.

[0030] In a further preferred embodiment of the present invention, a fixing bolt 16 is threadedly installed on one side of the support leg 1, and a sliding groove 17 is provided on one side of the extension leg 2, with one end of the fixing bolt 16 abutting against the sliding groove 17.

[0031] In this embodiment, the fixing bolt 16 is threaded onto one side of the support leg 1 to lock the position of the extension leg 2 and prevent it from sliding during operation. The slide groove 17 is provided on one side of the extension leg 2 and cooperates with the fixing bolt 16 to allow the extension leg 2 to slide relative to the support leg 1 within a certain range and be locked by the fixing bolt 16. When it is necessary to adjust the overall height of the fixture according to the height of the worktable or the frame, the fixing bolt 16 can be loosened to allow the extension leg 2 to slide freely in the slide groove 17. After adjusting to the required height, the fixing bolt 16 is tightened so that one end of it abuts against the slide groove 17, thereby locking the position of the extension leg 2.

[0032] In a further preferred embodiment of the present invention, a guide rod 18 is fixedly installed on the mounting bracket 5, and the guide rod 18 slides through the limiting plate 4.

[0033] In this embodiment, the guide rod 18 is fixedly installed on the mounting frame 5 to ensure the stability and straightness of the mounting frame 5 sliding on the limiting plate 4. The guide rod 18 slides through the limiting plate 4, providing a stable guide path for the mounting frame 5. When the mounting frame 5 slides on the limiting plate 4, the guide rod 18 ensures that the mounting frame 5 can move smoothly along the predetermined straight direction, avoiding deviation or shaking.

[0034] In a further preferred embodiment of the present invention, the top of the placement platform 3 is provided with a sliding opening for the two limiting plates 4 to slide.

[0035] In this embodiment, a sliding opening is provided on the top of the placement platform 3 to accommodate and guide the sliding of the two limiting plates 4, so that the limiting plates 4 can slide easily on the placement platform 3, thereby adapting to frames of different widths and greatly enhancing the flexibility and versatility of the fixture.

[0036] In summary, compared with related technologies, this device achieves high flexibility and versatility in welding fixtures for vehicle manufacturing, significantly improving the accuracy and efficiency of welding operations. It can quickly adapt to frames of different shapes and sizes, enhancing the stability and precision of the fixtures. This not only improves the quality and efficiency of welding operations but also reduces operational difficulty and time costs, providing the vehicle manufacturing industry with a more efficient and accurate welding solution.
