[0002] Electric vehicle or motorcycle swingarms are mostly composed of multiple components assembled together. During the production process, a positioning pin needs to be welded onto the swingarm hook. Currently, the production method for the swingarm hook and positioning pin involves workers first inserting the positioning pin into the mounting groove on the swingarm hook, and then manually welding the junction between the hook and the positioning pin. However, manual welding is limited by human factors and the worker's experience, resulting in low efficiency and problems such as uneven welding, incomplete welds, or false welds, affecting product quality. Therefore, there is an urgent need for a rotary welding device that is more efficient and can improve product quality. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] The purpose of this invention is to provide a rotary welding device to solve the problems existing in the prior art, thereby increasing work efficiency and improving product quality.
[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] This utility model provides a rotary welding device, such as Figure 1-2 As shown, it includes: a support structure 1, a position transformation structure 2, a first drive assembly, a second drive assembly, and a welding assembly 3. The position transformation structure 2 and the welding assembly 3 are both fixedly connected to the support structure 1. The position transformation structure 2 has a first rotating part and a second rotating part. The second rotating part is rotatably connected to the first rotating part. The first drive assembly is fixedly connected to the support structure 1, and the second drive assembly is fixedly connected to the position transformation structure 2. The first drive assembly can drive the first rotating part to rotate around a first rotating axis. The second rotating part is used to set a flat fork hook and a positioning post. The flat fork hook and the positioning post on the second rotating part can move to the welding position with the rotation of the first rotating part. The second rotating part can rotate around a second rotating axis under the drive of the second drive device. The welding assembly 3 can weld the flat fork hook and the positioning post located at the welding position together while the second rotating part rotates.
[0025] The rotary welding device provided by this utility model allows for manual installation of the flat fork hook and positioning post on the second rotating part. Then, driven by the first driving component, the first rotating part moves the second rotating part, along with the flat fork hook and positioning post on the second rotating part, to the welding position. Next, the first rotating part stops rotating, and the welding component 3 rotates around the second rotating part around the second rotating axis to weld the connection between the flat fork hook and the positioning post, thus welding the flat fork hook and the positioning post together. This eliminates the need for manual welding, resulting in higher work efficiency and avoiding problems such as uneven welding, missed welds, or false welds caused by human error, thereby improving product quality.
[0026] In this first embodiment, the position transformation structure 2 includes a rotating base 21 and a positioning fixture 22. A first driving component has a first output end, and the rotating base 21 is fixedly connected to the first output end. The first output end is rotatable around a first rotating shaft, and the rotating base 21 forms a first rotating part. A second driving component has a second output end, and the positioning fixture 22 is fixedly connected to the second output end. The second output end is rotatable around a second rotating shaft, and the positioning fixture 22 forms a second rotating part. The rotating base 21 stably supports the positioning fixture 22, and a flat fork hook and a positioning post can be installed on the positioning fixture 22.
[0027] In this first embodiment, the rotary welding device provided by this utility model further includes an unloading arm 4, which is fixedly connected to the support structure 1. The welding assembly 3 and the unloading arm 4 are arranged sequentially along the rotation direction of the rotating base 21. When the positioning fixture 22 rotates to below the unloading arm 4, the unloading arm 4 can move the welded flat fork hook and positioning post to the storage area. The unloading arm 4 can replace manual labor to complete the unloading work, thereby further reducing labor costs.
[0028] In this embodiment, both the first and second rotating shafts extend vertically, are parallel to each other and are spaced apart, and the positioning fixture 22 and the rotating base 21 are both horizontally arranged. The horizontally arranged positioning fixture 22 and rotating base 21 facilitate manual installation of the flat fork hook and positioning post by the operator.
[0029] In this first embodiment, multiple second drive components are provided. Each second drive component is sequentially and fixedly connected to the bottom of the rotating base 21 along the first circumferential trajectory. The first rotating shaft passes through the center of the first circumferential trajectory, and a positioning fixture 22 is fixedly connected to each second output end. During welding, a set of flat fork hooks and positioning posts can be installed on the first positioning fixture 22. Then, the rotating base 21 rotates, rotating the first positioning fixture 22 to the welding position for welding. At this time, the second positioning fixture 22 rotates to the loading position, and the loading can be restarted and the welding steps can be repeated, thereby further accelerating the welding speed and improving production efficiency.
[0030] In this first embodiment, the rotary welding device provided by this utility model further includes a control component 5. The control component 5 is fixedly connected to the support structure 1 and is signal-connected to the first drive component, the second drive component, the welding component 3, and the inclined arm. The control component 5 can control the opening and closing of the first drive component and the second drive component, the rotation speed, etc., and can also control the opening and closing of the welding component 3 or the action of the welding torch. The operator can control the operation of the entire rotary welding device by operating the control component 5.
[0031] To improve the stability of the device, in this first embodiment, the support structure 1 includes a leg 12 and a support plate 11. One end of the leg 12 is fixedly connected to one side of the support plate 11, and the leg 12 is used to support the ground.
[0032] In this first embodiment, when the positioning post is installed on the positioning fixture 22, the central axis of the positioning post coincides with the second rotating shaft. The trajectory of the connection between the positioning post and the flat fork hook is a circular trajectory, and the center of this circular trajectory passes through the central axis of the positioning post. This allows the positioning post to rotate around its own central axis when the positioning fixture 22 rotates. At this time, the welding torch only needs to contact the connection between the positioning post and the flat fork hook to complete the welding.
[0033] In this embodiment, the rotating base 21 has a circular cross-sectional shape along the horizontal direction.
[0034] In this embodiment, the positioning fixture 22 has a circular cross-sectional shape along the horizontal direction.
[0035] The circular rotating base 21 and the positioning fixture 22 have smooth edges, which can prevent workers from accidentally entering the rotating area and being bumped or scratched during the rotation process.
[0036] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
