DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes the present utility model in detail in conjunction with the drawings and specific preferred embodiments.

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "left side", "right side", "upper part", "lower part", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not represent the importance of components, so they cannot be understood as limitations to the present utility model. The specific dimensions adopted in this embodiment are only for illustrative purposes of the technical solution and do not limit the protection scope of the present utility model.

[0022] Embodiment 1: When performing circumferential welding on the bottleneck ring and head of a fire extinguisher, it is necessary for workers to place the bottleneck ring under the welding pen and then weld one by one. Each time, only one bottleneck ring and head can be welded, resulting in low work efficiency. Refer to Figure 1 and Figure 2, A rotary welding device for the bottleneck ring of a fire extinguisher, including a bracket 1 that bears the whole device. Above the bracket 1, a driving cylinder 3 is provided. The bottom of the driving cylinder 3 is connected to a welding pen 5 through a connecting plate 2. Below the welding pen 5, a rotating base 4 is provided. Inside the rotating base 4, an energy supply device and a rotating motor are arranged. The rotating motor is electrically connected to the energy supply device, and the rotating motor drives the rotating base 4 to rotate. Multiple driving motors 42 are also arranged on the rotating base 4. The driving motors 42 are electrically connected to the energy supply device, and the driving motors 42 drive the bottleneck ring to rotate. The welding pen 5 is aligned with the connection between the bottleneck ring and the head under the drive of the driving cylinder 3, thereby realizing the circumferential welding of the bottleneck ring and the head. Due to the existence of the shielding plate 21, when the welding pen 5 moves downward, the shielding plate 21 also moves downward. At this time, the welding pen 5 is shielded by the shielding plate 21, avoiding the harm caused to the staff by directly looking at the welding work;

[0023] During use, the staff place the bottleneck ring and the head above the driving motor 42. The rotating base 4 rotates to directly below the welding pen 5 under the drive of the rotating motor and stops rotating under the control of the control system. The welding pen 5 moves downward under the drive of the driving cylinder 3 until it is aligned with the connection between the bottleneck ring and the head. The control system controls the driving motor 42 to work, and the driving motor 42 rotates slowly, driving the bottleneck ring and the head to rotate. The welding pen 5 realizes the circumferential welding of the bottleneck ring and the head. After welding is completed, the welding pen 5 moves upward to separate from the bottleneck ring. The rotating base 4 continues to rotate, turning another bottleneck ring to directly below the welding pen 5 for a new round of welding. The staff remove the welded bottleneck ring and place a new bottleneck ring to be welded.

[0024] Embodiment 2: When the bottleneck ring is placed on the driving motor 42, it is difficult to fix the bottleneck ring, which may cause the welding position of the welding pen 5 to be inaccurate, thereby damaging the bottleneck ring. Therefore, referring to Figure 1 and Figure 3 , it can be seen that a bottleneck ring fixing seat 421 is provided on the driving motor 42, and a bottleneck ring fixing rod 311 is provided below the connecting plate 2. In order to further improve the welding accuracy, a second driving cylinder 32 is also provided on the connecting plate 2. The second driving cylinder 32 is connected to the welding pen 5 through a fixing bracket 321 to control the movement of the welding pen 5. A limiting port 3111 is provided at the lower part of the bottleneck ring fixing rod 311. At the same time, the auxiliary support rod 22 on the bracket 1 can ensure that the connecting plate 2 remains stable when moving downward, further improving the welding accuracy;

[0025] During use, the staff places the bottleneck ring on the bottleneck ring fixing seat 421. Driven by the rotating base 4, the bottleneck ring fixing seat 421 rotates under the welding pen 5. The first driving cylinder 31 drives the bottleneck ring fixing rod 311 to move downward. The limiting port 3111 of the bottleneck ring fixing rod 311 is clamped with the head, thus completing the positioning work of the bottleneck ring. The welding pen 5 performs circumferential welding on the bottleneck ring, improving the positioning accuracy of the bottleneck ring, and thus ensuring the welding precision.

[0026] Embodiment 3: When the rotating base 4 rotates, there is interference between the bracket 1 and the rotating base 4, which will affect the welding work. Therefore, referring to Figure 1 , it can be seen that a workbench surface 41 is provided directly above the rotating base 4. Six driving motors 42 are provided on the workbench surface 41. Driven by the rotating base 4, the bottleneck ring fixing seat 421 on the workbench surface 41 rotates under the welding pen 5 to perform welding work;

[0027] During use, place the fire extinguisher bottleneck ring in the bottleneck ring fixing seat 421 on the workbench surface 41. Adjust the first driving cylinder 31 to lower the bottleneck ring fixing rod 311 to the position where the bottleneck ring is fixed. Adjust the position of the welding pen 5 through the second driving cylinder 32 to make it in a state of ready to weld. Driven by the rotating motor, the rotating base 4 drives the workbench surface 41 to rotate. Six driving motors 42 are provided on the workbench surface 41, and each driving motor 42 is connected to a bottleneck ring fixing seat 421. When the bottleneck ring to be welded reaches under the welding pen 5 as the rotating base 4 rotates, stop rotating to ensure the accuracy of the welding position. The second driving cylinder 32 drives the welding pen 5 to move downward, aligning it with the connection between the bottleneck ring and the head. Start the welding power supply, and the welding pen 5 starts to work to complete the welding process. After welding is completed, the welding pen 5 rises and resets under the drive of the first driving cylinder 31 to continue the next welding. The rotating base 4 starts again to rotate the next bottleneck ring to be welded under the welding pen 5, and repeat the above steps until all bottleneck rings are welded. When welding is completed, remove the welded fire extinguisher bottleneck ring and clean the workbench surface 41 to prepare for the next batch of welding work. Through the workbench surface 41, the interference during the operation of the device is reduced, and at the same time, the working efficiency of bottleneck ring welding is improved.

[0028] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
