[0021] Figure 1-4This invention illustrates an embodiment of an electric vehicle frame welding positioning device, comprising a bracket 1. Rotatable shafts 2 are provided through both sides of the bracket 1. A flip frame 3 is fixedly connected between the two shafts 2. Rails 4 are fixedly connected to the front and rear sides of the inner cavity of the flip frame 3. Two sliding sleeves 5 are slidably connected to the surface of the rails 4. Fastening screws are provided through the sliding sleeves 5, abutting against the rails 4, and are threadedly connected to the sliding sleeves 5. A clamp 6 is provided on the top of the sliding sleeves 5, and the clamp 6 includes a lower clamp fixedly connected to the top of the sliding sleeve 5. The clamping plate 61 has an extension clamping plate assembly 62 at its top. A threaded rod 63 is rotatably connected to the top of the lower clamping plate 61. The extension clamping plate assembly 62 includes an upper clamping plate 621, which is threadedly connected to the surface of the threaded rod 63. A sliding cavity 622 is formed on one side of the upper clamping plate 621. An extension plate 623 is slidably connected to the inner cavity of the sliding cavity 622. Guide rods 64 are fixedly connected to both sides of the bottom of the upper clamping plate 621. The bottom of the guide rods 64 extends through to the bottom of the lower clamping plate 61 and slides with the lower clamping plate 61. The expansion plate 623 is connected to a threaded post 624 on one side of its top. The threaded post 624 extends to the top of the upper clamping plate 621. The top of the upper clamping plate 621 has a long groove 625 for the threaded post 624 to move. A threaded tube 626 is threaded onto the surface of the threaded post 624. Two symmetrical limiting pins 627 are fixedly connected to one side of the top of the expansion plate 623. The top of the upper clamping plate 621 has a long groove 628 for the limiting pins 627 to slide. A flipping drive assembly is located between the left rotating shaft 2 and the bracket 1. Component 7, the flip drive assembly 7 includes a fixed box 71 fixedly connected to the left side of the bracket 1, a gear 72 fixedly connected to the surface of the front rotating shaft 2 located in the inner cavity of the fixed box 71, a cylinder 73 fixedly installed in the inner cavity of the fixed box 71, a connecting plate 74 fixedly installed at the output end of the cylinder 73, a rack 75 fixedly connected to the top of the connecting plate 74, the rack 75 meshing with the gear 72, and two symmetrical guide rods 76 fixedly connected to the inner cavity of the fixed box 71, the connecting plate 74 slidably connected to the surface of the two guide rods 76.

[0022] Working principle: When using this utility model, the clamp 6 drives the sliding sleeve 5 to slide on the surface of the track 4. Adjust the clamp 6 to a suitable position, tighten the screws on the sliding sleeve 5, and lock the position of the clamp 6. Place the electric vehicle frame on the flip frame 3 and rest it on the top of the lower clamping plate 61. Pull the extension plate 623 to slide in the inner cavity of the sliding cavity 622. The extension plate 623 then drives the threaded column 624 to slide in the inner cavity of the long groove 625. After adjusting the appropriate downward pressure range, tighten the threaded tube 626 to press against the upper clamping plate 621. The upper extension plate 623 is locked in place by friction. Then, the threaded rod 63 is operated, and the thread causes the upper clamping plate 621 and the extension plate 623 to move downward. The cooperation with the lower clamping plate 61 fixes the electric vehicle frame. After the single-sided welding is completed, the cylinder 73 can be extended, and the rack 75 can be moved by the connecting plate 74. The rack 75 drives the gear 72 and the rotating shaft 2 to rotate. The rotating shaft 2 drives the flipping frame 3 to rotate, so that the fixed electric vehicle frame can also be flipped over, which facilitates the welding operation on the other side.

[0023] In summary, this electric vehicle frame welding and positioning device uses clamp 6 to drive sliding sleeve 5 to slide on the surface of track 4. By adjusting clamp 6 to a suitable position, the electric vehicle frame is placed on flip frame 3 and rests on top of lower clamping plate 61. Pulling extension plate 623 adjusts the downward pressure range, and operating threaded rod 63 moves upper clamping plate 621 and extension plate 623 downward to fix the electric vehicle frame. After single-sided welding is completed, flip frame 3 can be flipped over by flip drive component 7, so that the fixed electric vehicle frame can also be flipped over. This achieves the purpose of fixing electric vehicle frames of various specifications, and the fixed electric vehicle frame can be automatically flipped over to ensure continuous welding on both sides of the electric vehicle frame.
