[0021] 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. Example 1

[0022] Please see Figures 1 to 6 This utility model provides a technical solution: a welding fixture for metal shells, including a base 1. A first fixing plate 2 and a second fixing plate 3 are fixedly connected to the top and bottom of the base 1, respectively. Connecting grooves 16 are provided on the top of the first fixing plate 2 and the bottom of the second fixing plate 3. Connecting rods 4 pass through the two connecting grooves 16. The connecting rods 4 are slidably connected to the base 1 and the first fixing plate 2 and the second fixing plate 3, respectively. A first rotating plate 5 and a second rotating plate 6 are rotatably connected to the outer ends of the connecting rods 4, respectively. The inner wall of the second rotating plate 6 is slidably connected to the outer wall of the connecting rod 4. A first clamping plate 7 is fixedly connected to the front of the first rotating plate 5 and the left side wall of the first fixing plate 2. Placement grooves are provided on the back of the first rotating plate 5 and the right side wall of the first fixing plate 2. An electric telescopic rod 8 is fixedly connected to the inner wall of the placement groove. A connecting plate 9 is fixedly connected to the telescopic end of the electric telescopic rod 8. The first fixing plate 2 and the second fixing plate 3 are both located on the right half of the base 1, and the first fixing plate 9 is fixedly connected to the right side of the base 1. Plate 2 and the second fixed plate 3 are symmetrically distributed on the base 1. The first rotating plate 5 and the second rotating plate 6 are located at the top of the upper half of the connecting groove 16 and the bottom of the lower half of the connecting groove 16, respectively. There are two sets of the first clamping plate 7 and the placement groove. The first outer rod 10 is fixedly connected to the side of the connecting plate 9 facing the first clamping plate 7. The side of the first outer rod 10 facing the first clamping plate 7 has a first groove 11. The inner wall of the first groove 11 is fixedly connected to the first spring 12. The end of the first spring 12 away from the inner wall of the first groove 11 is fixedly connected to the first inner rod 13. The end of the first inner rod 13 away from the connecting plate 9 is fixedly connected to the second clamping plate 14. The second clamping plate 14 is located at the top of the first rotating plate 5 and the first fixed plate 2, respectively. The bottom of the first rotating plate 5 and the top of the second rotating plate 6 are both fixedly connected to the support block 15. The bottom and top of the two support blocks 15 are respectively close to the top and bottom of the base 1. The first clamping plate 7 and the second clamping plate 14 are both made of rubber.

[0023] When using this fixture, existing welding jigs for metal shells cannot clamp metal plates of different thicknesses, limiting their application. Therefore, a welding jig for metal shells is developed. When clamping a metal plate, the telescopic end of the electric telescopic rod 8 extends, causing the connecting plate 9 to move the second clamping plate 14 away from the first clamping plate 7. Then, the two metal plates are placed on top of the first fixed plate 2 and the first rotating plate 5, respectively, so that one side of the metal plate is pressed against the first clamping plate 7. Subsequently, the telescopic end of the electric telescopic rod 8 is retracted, causing the connecting plate 9 to move the second clamping plate 14 towards the metal plate, so that the second clamping plate 14 is pressed against the metal plate. Through the cooperation of the first spring 12 with the first clamping plate 7 and the second clamping plate 14, the deformation of the metal plate due to excessive force during clamping can be prevented. Example 2

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a welding fixture for metal shells, wherein a first sliding groove 17 is provided on the top of the base 1, and a second sliding groove 18 is provided on both the top and bottom of the base 1. The first sliding groove 17 and the second sliding groove 18 are both arc-shaped and share the same center. The first sliding groove 17 penetrates the base 1, and a plurality of scale grooves 19 are provided on the outer end of the first sliding groove 17. The two second sliding grooves 18 are symmetrically distributed vertically. A plurality of locking slots 20 are provided on the inner wall of the second sliding grooves 18. A scale rod 21 is slidably connected inside the locking slot 20. The number of scale rods 21 and scale grooves 19 are the same and correspond one-to-one. The bottom of the first rotating plate 5 is fixed. A second outer rod 22 is fixedly connected to the first sliding groove 17. The second outer rod 22 is located inside the first sliding groove 17. A second groove 23 is formed at the bottom of the second outer rod 22. A second spring 24 is fixedly connected to the inner top wall of the second groove 23. A second inner rod 25 is fixedly connected to the bottom of the second spring 24. The second inner rod 25 is slidably connected to the inner wall of the second groove 23. The bottom of the second inner rod 25 is fixedly connected to the top of the second rotating plate 6. A pull rod 26 is fixedly connected to the bottom of the second rotating plate 6. A locking rod 27 is fixedly connected to the top of the second rotating plate 6. The size of the locking rod 27 is the same as that of the locking groove 20 and the locking rod 27 is located inside the locking groove 20.

[0025] While existing welding fixtures for metal shells can adjust the assembly angle, they cannot quickly and accurately adjust the angle, which is inconvenient. Therefore, a welding fixture for metal shells is proposed. After the metal plate is clamped, pulling the lever 26 downwards causes the second rotating plate 6 to drive the second inner rod 25 downwards along the connecting rod 4. When the second inner rod 25 moves downwards, the second spring 24 is in a stretched state, and the locking lever 27 moves downwards with the second rotating plate 6. When the locking lever 27 moves below the second slide groove 18, pulling the lever 26 begins to rotate. By cooperating with the second outer rod 22 and the second inner rod 25, the first rotating plate 5 can rotate with the second rotating plate 6. When the first rotating plate 5 rotates to a suitable angle, the pull rod 26 is released, causing the second spring 24 to drive the second inner rod 25 and the second rotating plate 6 to rebound upwards, thereby causing the locking rod 27 to enter the corresponding locking groove 20, thus preventing the second rotating plate 6 and the first rotating plate 5 from moving. At this time, the scale rod 21 is lifted by the locking rod 27. By cooperating with the scale rod 21 and the scale groove 19, the welding fixture for metal shells has the effect of making it convenient for workers to observe the angle.

[0026] 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.
