[0002] Modern industry is increasingly moving towards full automation, and robot-based production lines are gradually becoming the mainstream in modern factories. This is especially true in automobile manufacturing companies, where the main technology and manufacturing hubs—the welding workshops—are increasingly adopting highly automated robotic welding guns.

[0003] With the rapid development of industrial automation, aluminum and its alloys are increasingly widely used in the automotive, aerospace, and electronics industries. However, the high thermal and electrical conductivity of aluminum makes it difficult to weld, and traditional welding methods cannot meet the demands for high-quality and high-efficiency welding. Robotic aluminum spot welding technology has emerged as a result. Due to the different welding positions and postures, the requirements for the welding gun also differ, and they are generally divided into C-type welding guns and X-type welding guns.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example 1

[0021] Please see Figure 1 - Figure 2A robotic aluminum spot welding clamp includes an aluminum C-welding clamp structure and an aluminum X-welding clamp. The aluminum C-welding clamp structure includes two aluminum side plates 1. A transformer mounting plate 2 is fixedly installed at the tail of the aluminum side plate 1. A transformer body 3 is threadedly connected to the tail of the transformer mounting plate 2. Conductive terminals 4 are fixedly installed on the transformer body 3 through positive and negative terminals respectively. A stationary arm flexible connection 5 is fixedly installed on the inner wall of the aluminum side plate 1. A stationary aluminum arm 6 is fixedly installed at the bottom of the stationary arm flexible connection 5. The device is equipped with a boom-side flexible connector 7. A boom clamp 8 is threadedly connected to the outer wall of the boom-side flexible connector 7. An electrode assembly 9 is fixedly installed on the outer wall of the boom clamp 8. A guide mechanism 10 is fixedly installed on the inner wall of the aluminum side plate 1. An electric cylinder mounting block 12 is fixedly installed on the inner wall of the aluminum side plate 1. An electric cylinder body 11 is fixedly installed on the outer wall of the electric cylinder mounting block 12. An electric cylinder connecting shaft 13 is threadedly connected to the telescopic end of the electric cylinder body 11. A welding clamp bracket flange 14 is fixedly installed on the top of the aluminum side plate 1.

[0022] In the above structure, mounting holes are provided at the tail of the two aluminum side plates 1, so that the transformer mounting plate 2 can be installed at the tail of the aluminum side plate 1 through the mounting holes and bolts provided at the tail of the aluminum side plate 1.

[0023] In a preferred embodiment, the electric cylinder body 11 is connected to the boom holder 8 by a clamping engagement.

[0024] In the above structure, when the electric cylinder body 11 is started, its telescopic end moves, which in turn causes the telescopic end of the electric cylinder body 11 to be clamped by the boom clamp 8, causing the telescopic end of the electric cylinder body 11 to drive the boom clamp 8 and the electrode assembly 9 to move linearly on the guide mechanism 10.

[0025] In a preferred embodiment: the positive and negative terminals of the transformer body 3 are located outside the stationary arm side flexible connection 5 at the end near the installation of the conductive terminal 4, and the positive and negative terminals of the transformer body 3 are connected to the stationary arm side flexible connection 5 through the conductive terminal 4.

[0026] In the above structure, the positive and negative poles of the transformer body 3 are connected to the conductive terminal 4, so that the transformer body 3 can output power to the outside through the positive and negative poles. Furthermore, through the connection between the conductive terminal 4 and the stationary arm side flexible connection 5, the transformer body 3 can output power to the stationary arm side flexible connection 5 through the conductive terminal 4 provided with the positive and negative poles.

[0027] Working principle: Activating the electric cylinder body 11 moves the telescopic end of the electric cylinder body 11, causing the mounting block 12 to move. The mounting block 12 then moves the boom clamp 8, which in turn moves the electrode assembly 9. The boom clamp 8 and the electrode assembly 9 move laterally at the top of the guide mechanism 10, causing the electrode assembly 9 to separate from the contact point of the stationary aluminum arm 6. At this time, a gap is created between the electrode assembly 9 and the stationary aluminum arm 6. The object to be spot-welded is placed between the electrode assembly 9 and the stationary aluminum arm 6. Activating the electric cylinder body 11 pushes the boom clamp 8 and the electrode assembly 9 towards the stationary aluminum arm 6, thus clamping the object to be welded between the stationary aluminum arm 6 and the electrode assembly 9. At this time, the transformer body 3 outputs power to the stationary arm side flexible connection 5 through the conductive terminal 4. The stationary arm side flexible connection 5 inputs power to the stationary aluminum arm 6, thus enabling the stationary aluminum arm 6 and the electrode assembly 9 to spot weld the object. Example 2

[0028] Please see Figure 3 - Figure 4 In a preferred embodiment: the aluminum spot welding clamp structure includes an aluminum side plate 15, a transformer mounting plate 16 fixedly installed on the inner wall of the aluminum side plate 15, a transformer body 17 fixedly installed on the top of the transformer mounting plate 16, conductive terminals 18 connected to the positive and negative poles of the transformer body 17, a stationary boom flexible connection 19 fixedly installed on the inner wall of the aluminum side plate 15, a stationary aluminum boom 20 fixedly installed at the bottom of the stationary boom flexible connection 19, and a boom flexible connection 21 fixedly installed on the inner wall of the aluminum side plate 15. A movable aluminum arm 22 is rotatably connected. An electric cylinder mounting block 24 is rotatably connected to the inner wall of the aluminum side plate 2 15. An electric cylinder body 23 and an electric cylinder central shaft assembly 25 are fixedly installed on the outer wall of the electric cylinder mounting block 24. One end of an electric cylinder connecting shaft 26 is fixedly installed at the telescopic end of the electric cylinder body 23. The other end of the electric cylinder connecting shaft 26 is rotatably connected to an X-type welding clamp arm connecting shaft assembly 27. An X-type welding clamp central shaft assembly 28 is rotatably connected to the inner wall of the aluminum side plate 2 15. A welding clamp bracket body 29 is fixedly installed on the top of the aluminum side plate 2 15.

[0029] In the above structure, the aluminum side plate 2 15 has mounting holes at its tail. The transformer mounting plate 2 16 is fixed in the mounting holes by aligning the screws with the mounting holes at the tail of the aluminum side plate 2 15. Thus, the transformer mounting plate 2 16 is fixedly installed at the tail of the aluminum side plate 2 15 by the mounting holes.

[0030] In a preferred embodiment: the top of the movable aluminum arm 22 near the electric cylinder connecting shaft 26 is located at the bottom of the X-type welding clamp shaft assembly 28, and the top of the movable aluminum arm 22 near the electric cylinder connecting shaft 26 is rotatably connected to the aluminum side plate 1.

[0031] In the above structure, by activating the electric cylinder body 23, the telescopic end of the electric cylinder body 23 drives the electric cylinder connecting shaft 26 to move, which in turn drives the bottom of the moving aluminum arm 22 to move, thereby causing the moving aluminum arm 22 to generate a circular motion around the X-shaped welding clamp shaft assembly 28.

[0032] In a preferred embodiment, there are two aluminum side plates 15, and the two aluminum side plates 15 are arranged symmetrically.

[0033] Working principle: By activating the electric cylinder body 23, the telescopic end of the electric cylinder body 23 drives the electric cylinder connecting shaft 26 to move, which in turn drives the bottom of the moving aluminum arm 22 to move. This causes the moving aluminum arm 22 to rotate around the X-shaped welding clamp shaft assembly 28. At this time, the side of the moving aluminum arm 22 away from the electric cylinder connecting shaft 26 moves downward, causing the moving aluminum arm 22 to separate from the stationary aluminum arm 20. A gap is then created between the moving aluminum arm 22 and the stationary aluminum arm 20. By placing the workpiece to be welded between the moving aluminum arm 22 and the stationary aluminum arm 20, activating the electric cylinder body 23 resets the structure, allowing the moving aluminum arm 22 and the stationary aluminum arm 20 to clamp the workpiece. The moving aluminum arm 22 and the stationary aluminum arm 20 then perform spot welding on the workpiece.

[0034] In the above structure, the two aluminum side plates 15 are symmetrically arranged, so that a gap is formed between the two aluminum side plates 15, and the gap space between the two aluminum side plates 15 forms the installation space of the X-shaped welding clamp.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
