[0035] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0036] Example:

[0037] like Figures 1-4 As shown, an adjustable welding fixture with automatic weld seam alignment includes:

[0038] The fixed mounting base 1 has mounting feet at both ends;

[0039] The connecting drive mechanism 2 is fixedly mounted at the top center of the fixed mounting base 1;

[0040] The movable mounting base 3 is fixedly disposed on the outside of the output end of the connecting drive mechanism 2;

[0041] The fixed limiting mechanism 4 is fixedly installed on the front and rear surfaces of the movable mounting base 3;

[0042] Fixed limiting plate 5, which is fixedly installed on the front and rear surfaces of the movable mounting base 3;

[0043] The movable connecting plug 6 is movably engaged between the fixed limiting mechanism 4 and the fixed limiting plate 5;

[0044] The connecting clamping mechanism 7 is fixedly disposed at the end of the movable connecting plug 6 and is located on top of the movable mounting base 3.

[0045] The working principle of the above technical solution is as follows:

[0046] During use, the material to be welded can be placed inside the connecting clamping mechanism 7, and the material to be welded is clamped and fixed under the action of the connecting clamping mechanism 7. Then, under the action of the connecting drive mechanism 2 driving the movable mounting base 3, the movable mounting base 3 drives the fixed limiting mechanism 4, the fixed limiting plate 5, the movable connecting plug 6, the connecting clamping mechanism 7 and the material to be welded to move, so that the required welding position is aligned with the welding gun, thereby enabling stable welding of the material to be welded, and the operation is convenient.

[0047] In another embodiment, such as Figure 3 As shown, the connection drive mechanism 2 includes a connection frame 21, one end of which is fixedly connected to a first servo motor 22, and the output end of the first servo motor 22 is fixedly connected to an adjusting threaded rod 23.

[0048] This facilitates the first servo motor 22 to drive the adjusting threaded rod 23, enabling the movable mounting base 3 to move stably when the adjusting threaded rod 23 rotates, making operation convenient.

[0049] In another embodiment, such as Figure 3As shown, the outer side of the bottom surface of the movable mounting base 3 slides and fits against the inner side of the connecting frame 21, and the interior of the movable mounting base 3 is provided with a thread that matches the adjusting threaded rod 23.

[0050] The adjustable threaded rod 23 can move stably on the inner side of the connecting frame 21 and the outer side of the surface of the adjustable threaded rod 23, making operation convenient.

[0051] In another embodiment, such as Figure 2 As shown, the connecting clamping mechanism 7 includes a mounting base plate 71. A fixed connecting end plate 72 is fixedly connected to the top end of the mounting base plate 71. A rectangular through groove is formed on the surface of the fixed connecting end plate 72. A movable mounting frame 73 is movably connected to the inner side of the fixed connecting end plate 72. A second servo motor 74 is fixedly connected to the inner side of the movable mounting frame 73. A rotating clamping anti-slip block 75 is fixedly connected to the output end of the second servo motor 74. A fixed mounting bracket 76 is fixedly connected to one side of the fixed connecting end plate 72. An electric telescopic rod 77 is fixedly connected to one side of the fixed mounting bracket 76. The output end of the electric telescopic rod 77 passes through the interior of the fixed mounting bracket 76 and extends to the inner side of the fixed mounting bracket 76, and is fixedly connected to the movable mounting frame 73.

[0052] The material to be welded is placed between the fixed connection end plates 72. Then, the electric telescopic rod 77 can push the movable mounting frame 73, the second servo motor 74 and the rotating clamping anti-slip block 75 to clamp and fix the material to be welded. At the same time, the second servo motor 74 can drive the rotating clamping anti-slip block 75, thereby driving the material to be welded to rotate, which facilitates the welding process between the materials to be welded.

[0053] In another embodiment, such as Figure 4 As shown, the fixed limiting mechanism 4 includes a connecting mounting plate 41. A connecting sleeve block 42 is fixedly connected to one side of the connecting mounting plate 41. A movable insert rod 43 is movably connected inside the connecting sleeve block 42 and the connecting mounting plate 41. A force-bearing collar 44 is fixedly sleeved on the outer surface of the movable insert rod 43. The force-bearing collar 44 is located inside the connecting sleeve block 42. A force-bearing spring 45 is fixedly connected between one side of the force-bearing collar 44 and one end inside the connecting sleeve block 42. A connecting pull block 46 is fixedly connected to one end of the movable insert rod 43. A fixed connecting arm 47 is fixedly connected to one end of the connecting pull block 46. A connecting pull rod 48 is fixedly connected to one side of the fixed connecting arm 47. A connecting pull ring 49 is fixedly connected to the other end of the connecting pull rod 48.

[0054] The connecting ring 49 is easy to pull, which moves the connecting rod 48, thereby moving the fixed connecting arm 47, the connecting block 46, the movable insert rod 43 and the force-bearing collar 44. This compresses the force-bearing spring 45, allowing the end of the movable insert rod 43 to move and retract towards the inside of the connecting sleeve 42, thus enabling quick adjustment and convenient use.

[0055] In another embodiment, such as Figure 2 and Figure 4 As shown, the movable connecting plug 6 slides and fits against the connecting mounting plate 41 and the fixed limiting plate 5.

[0056] The bottom end of the movable connecting plug 6 can be stably inserted between the connecting mounting plate 41 and the fixed limiting plate 5 to restrict the connection.

[0057] In another embodiment, such as Figure 2 and Figure 4 As shown, the movable connecting plug 6 has a through hole inside that is adapted to the movable plug rod 43.

[0058] This allows the end of the movable plug 43 to be stably inserted into the interior of the movable connecting plug 6, thereby limiting the connection and making operation convenient.

[0059] The working principle of this utility model is as follows: During use, the materials to be welded are placed between the fixed connecting end plates 72. Then, the electric telescopic rod 77 pushes the movable mounting frame 73, the second servo motor 74, and the rotating clamping anti-slip block 75 to clamp and fix the materials to be welded. Next, the first servo motor 22 drives the adjusting threaded rod 23, so that the movable mounting base 3, the fixed limiting mechanism 4, the fixed limiting plate 5, the movable connecting block 6, the connecting clamping mechanism 7, and the materials to be welded can move, so that the connection between the materials to be welded is aligned with the welding gun. At the same time, the second servo motor 74 drives the rotating clamping anti-slip block 75, thereby causing the materials to be welded to rotate, facilitating the connection between the materials to be welded. In subsequent use, when the connecting clamping mechanism 7 needs to be disassembled for inspection and maintenance, the connecting pull ring 49 is pulled, which moves the connecting pull rod 48. This moves the fixed connecting arm 47, the connecting pull block 46, the movable insert rod 43, and the force-bearing collar 44, compressing the force-bearing spring 45. This causes the end of the movable insert rod 43 to move and retract towards the inside of the connecting sleeve block 42, allowing for quick adjustment. The end of the movable insert rod 43 is then pulled out from inside the movable connecting insert block 6, thus removing the restriction on the movable connecting insert block 6. This allows for the disassembly of the movable connecting insert block 6 and the connecting clamping mechanism 7, and facilitates inspection and maintenance of the connecting clamping mechanism 7. The overall structure is simple and easy to use.

[0060] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
