[0026] Embodiment:

[0027] Referring to Figures 1-6 As shown, a welding tooling for the pole of a thermal battery cover includes a workbench 1. Support legs 2 are evenly arranged on the bottom surface of the workbench 1, and a fixing block 3 is arranged on the top surface. A rotating disk 5 is arranged on the fixing block 3. A limiting shaft 12 is arranged at the center of the rotating disk 5. A clamping tooling 6 is sleeved on the limiting shaft 12. A limiting groove 601 is arranged on the top surface of the clamping tooling 6. A servo motor 4 is further arranged on the bottom surface of the workbench 1. The output shaft of the servo motor 4 penetrates through the workbench 1 and the fixing block 3 and is connected to the center of the rotating disk 5. A support block 7 is also arranged on the workbench 1. A support shaft 8 is arranged on the support block 7. A rotating arm 9 is arranged on the support shaft 8. A welding needle 10 corresponding to the position of the limiting shaft 12 is arranged on the rotating arm 9.

[0028] The fixing block 3 installs and supports the rotating disk 5. The rotation of the rotating disk 5 drives the clamping tooling 6 to rotate. The battery cover to be processed is clamped in the limiting groove 601 of the clamping tooling 6, and the pole is placed in the welding positioning hole 602. The clamping tooling 6 is positioned on the rotating disk 5 through the cooperation of the welding positioning hole 602 and the limiting shaft 12. The servo motor 4 drives the rotating disk 5 to rotate, thereby driving the clamping tooling 6 to rotate. The welding needle 10 corresponds to the position of the limiting shaft 12, so that the welding needle 10 is located at the connection between the battery cover and the pole. As the battery cover rotates, the connection between the battery cover and the pole is welded together, and the pole is welded and fixed on the battery cover. Since the servo motor 4 rotates evenly, the uniformity of welding is ensured, and the quality of the product is guaranteed.

[0029] Further, a welding positioning hole 602 corresponding to the product processing position is opened in the limiting groove 601 of the clamping tooling 6, and the diameter of the limiting shaft 12 matches the diameter of the welding positioning hole 602.

[0030] The limiting shaft 12 matches with the welding positioning hole 602 to ensure accurate positioning of the clamping tooling 6, prevent the clamping tooling 6 from loosening, and avoid the connection point between the battery cover clamped on the clamping tooling 6 and the pole column from not corresponding to the welding position, resulting in welding failure and affecting the product quality. In addition, by positioning the clamping tooling 6 through the welding positioning hole 602 and the limiting shaft 12, the operation is simple and convenient.

[0031] Furthermore, a positioning pin 603 matching the product is also provided in the limiting groove 601 of the clamping tooling 6.

[0032] The position of the positioning pin 603 corresponds to the position of the hole on the battery cover. The battery cover is positioned by the cooperation of the positioning pin 603 and the hole to prevent the position of the battery cover from shifting during welding and ensure the product quality.

[0033] Furthermore, a first elastic groove 604 is opened on the side surface of the clamping tooling 6 corresponding to the position of the limiting groove 601, and a first locking threaded hole 605 is provided on the adjacent side wall corresponding to the position of the first elastic groove 604.

[0034] By setting a locking bolt in the first locking threaded hole 605 to press the first elastic groove 604, the first elastic groove 604 corresponds to the position of the limiting groove 601. When the first elastic groove 604 is pressed, the opposite side walls move towards each other, and then the side surface of the battery cover is pressed, thereby fixing the battery cover in the limiting groove 601.

[0035] Furthermore, a through hole 902 is provided at a position near one end of the rotating arm 9, and a second elastic groove 901 communicating with the through hole 902 is opened on this surface. A second locking threaded hole 903 is provided on the side surface of the rotating arm 9 corresponding to the position of the second elastic groove 901; a welding needle 10 is provided on the side surface of the rotating arm 9 near the other end.

[0036] A locking nut is set in the second locking threaded hole 903. When the locking nut is tightened, the opposite side walls of the second elastic groove 901 move towards each other. The through hole 902 on the rotating arm 9 communicates with the second elastic groove 901. When the side walls of the second elastic groove 901 move towards each other, the through hole 902 will contract inward, and the rotating arm 9 is sleeved on the support shaft 8 through the through hole 902, so that the inner wall of the through hole 902 is pressed against the support shaft 8, thereby fixing the position of the rotating arm 9.

[0037] Furthermore, a bearing 11 is clamped at the connection between the fixed block 3 and the rotating disk 5. The output shaft of the servo motor 4 passes through the bearing 11 and is fixedly connected to the rotating disk 5, and the center line of the output shaft of the servo motor 4 is coaxially arranged with the center line of the limiting shaft 12 on the rotating disk 5.

[0038] The bearing 11 is clamped at the connection between the fixed block 3 and the rotating disk 5. The fixed block 3 is fixedly arranged on the workbench 1, and the output shaft of the servo motor 4 drives the rotating disk 5 to rotate after passing through the fixed disk. A clamping tooling 6 is sleeved on the limiting shaft 12 of the rotating disk 5, thereby driving the clamping tooling 6 to rotate.

[0039] During use, the servo motor 4 is installed on the lower surface of the workbench 1, the fixed block 3 is installed on the upper surface of the workbench 1, and the output shaft of the servo motor 4 penetrates through the fixed block 3. Then, a rotating disk 5 is arranged above the fixed block 3, a bearing 11 is arranged on the output shaft of the servo motor 4, and the bearing 11 is located between the fixed block 3 and the rotating disk 5. The output shaft of the servo motor 4 is connected to the rotating disk 5, so that the servo motor 4 can drive the rotating disk 5 to rotate. A limiting groove 601 is formed in the clamping tooling 6, a welding positioning hole 602 and a positioning pin 603 are arranged on the bottom surface of the limiting groove 601. The clamping tooling 6 is sleeved on the limiting shaft 12 on the rotating disk 5 through the welding positioning hole 602. The battery cover to be processed is placed in the limiting groove 601, and the pole column to be welded is placed in the welding positioning hole 602, so that the welding position on the battery cover corresponds to the position of the pole column. At the same time, the position of the battery cover is positioned by the positioning pin 603. After the battery cover is placed, through the locking bolt cooperating with the first locking thread hole 605, the two opposite side walls of the first elastic groove 604 move towards each other, so that the side wall of the battery cover is closely attached to the inner side wall of the limiting groove 601, thereby locking and fixing the battery cover in the limiting groove 601. At the same time, a rotating arm 9 is sleeved on the support shaft 8, and the rotating arm 9 is fixed through the locking bolt cooperating with the second elastic groove 901, so that the position of the welding needle 10 on the rotating arm 9 corresponds to the welding position on the battery cover.

[0040] Start the servo motor 4, so that the servo motor 4 drives the rotating disk 5 to rotate, thereby driving the clamping tooling 6 on the rotating disk 5 to rotate, so that the battery cover rotates, while the position of the welding needle 10 remains unchanged, and the processing position on the battery cover rotates with the welding needle 10 to form an annular welding line, and the pole column is welded on the battery cover. The servo motor 4 drives the battery cover to rotate evenly, thereby making the welding line uniform and improving the product quality.

[0041] In actual use, adjustable feet are arranged at the bottom of the support legs 2, so that the workbench 1 is in a horizontal state, ensuring that after the battery cover and the pole column are installed, their connection surfaces can accurately contact, and then when the servo motor 4 drives the rotation, they can be accurately welded together, further ensuring the product quality.

[0042] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model; without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.
