Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and specifically to an automatic welding equipment for welding containers. Background Technology

[0002] With the development of digitalization, automation, computer technology, and mechanical design, and the increasing emphasis on welding quality, automatic welding has evolved into an advanced manufacturing technology. Automatic welding equipment is playing an increasingly important role in various industries, and its application scope is rapidly expanding. In modern industrial production, the mechanization and automation of the welding process is an inevitable trend in the modernization of the welding equipment manufacturing industry.

[0003] Chinese Patent CN206795106U discloses an automatic welding device for container welding, including a robotic arm. The robotic arm has a mounting groove at its bottom, within which a welding gun is movably mounted. The welding gun, located within the mounting groove, has a mounting hole, within which a mounting post is movably mounted. On either side of the mounting hole are first through holes and positioning grooves located on the inner walls of the mounting groove. One end of the mounting post is movably positioned within the positioning groove, while the other end movably passes through the first through hole and extends to its outer side. A rack is fixedly welded to the mounting post, and a gear is meshed with the rack. A rotating groove is located on one side of the bottom of the robotic arm, within which a rotating seat is fixedly mounted, and a rotating rod is rotatably mounted within the rotating seat. This invention features a simple structure, convenient operation, easy disassembly of the welding gun, and ease of maintenance, thus meeting people's needs.

[0004] However, the above technical solutions have the following shortcomings: the welding gun is directly connected to the robotic arm, which requires a high degree of freedom of the robotic arm. On the one hand, the higher the degree of freedom of the robotic arm, the more joints there are, which increases the cost. Moreover, each joint requires an independent servo system, and the cost increases linearly with the number of joints. On the other hand, a high degree of freedom robotic arm requires more complex algorithm support, which increases the debugging and maintenance costs. Utility Model Content

[0026] The rotating mechanism is mounted on the mounting ring 5. The rotating mechanism includes a rotating cylinder 31, a mounting plate 32, and a drive assembly. The rotating cylinder 31 is mounted on the mounting ring 5. The mounting plate 32 is fixedly connected to the rotating cylinder 31. The drive assembly is mounted on the mounting ring 5. One end of the drive assembly is connected to the rotating cylinder 31.

[0027] There are two support plates 6, and an installation cylinder 7 is rotatably connected between the two support plates 6. A welding gun 8 is detachably connected to the installation cylinder 7. A groove 9 is opened on the inner wall of the installation cylinder 7. A guide rail 10 that matches the groove 9 is fixedly connected to the surface of the welding gun 8. A locking bolt 11 is provided on the installation cylinder 7. The locking bolt 11 passes through the installation cylinder 7 and is threadedly connected to the installation cylinder 7.

[0028] The adjustment mechanism is set inside the support cylinder 2. One end of the adjustment mechanism is connected to the connecting seat 1, and the other end of the adjustment mechanism is connected to the mounting cylinder 7 to adjust the tilt angle of the mounting cylinder 7 and the welding torch 8.

[0029] Example 2

[0030] like Figure 2As shown, this utility model proposes an automatic welding device for container welding. Compared with Embodiment 1, this embodiment also specifically discloses the structure of the drive assembly. The drive assembly includes a drive motor 331, a drive worm 332, and a drive worm wheel 333. The drive motor 331 is mounted on the mounting ring 5 and has forward and reverse rotation functions.

The drive worm wheel 333 is fixedly connected to the rotating cylinder 31 and is adapted to the drive worm 332.

[0031] Example 3

[0032] like Figure 3-4 As shown, this utility model proposes an automatic welding device for welding headers. Compared with Embodiment 2, this embodiment also specifically discloses the structure of the adjustment mechanism. The adjustment mechanism includes a telescopic rod 41, a movable plate 42, a top rod 43, and a connecting assembly. The telescopic rod 41 is installed inside the support cylinder 2. The telescopic rod 41 is an electric telescopic rod and is connected to the control system and power supply through a wire. The telescopic rod 41 is fixedly connected to the connecting seat 1.
