[0016] Working Principle: During operation, the dissimilar metal to be processed is placed on the worktable. Motor 2 drives shaft 1 to rotate, and electric actuator 1 moves the T-shaped slider 1. When clamping the workpiece, the teeth of gear 2 mesh with those of gear 1, causing the connecting rod to rotate. This clamps the workpiece between the rubber pad and the clamping block. After clamping, electric actuator 1 moves gear 2, causing its teeth to mesh with those of rack plate 2, disengaging from gear 1. The rack plate 2 then limits gear 2's rotation, preventing further rotation and maintaining a fixed position for the rubber pad and slider 2. This stable clamping of the workpiece enhances its stability during welding. Shaft 1 drives two pulleys 1 to rotate, moving the movable frame on the worktable. This allows adjustment of the welding torch and electric grinder's left and right positions on the worktable according to the workpiece's shape, size, or processing requirements.

[0017] Motor 1 drives shaft 2 to rotate, which in turn drives gear 3 to rotate, which in turn drives two gears 4 to rotate. The rotation of one of the gears 4 drives shaft 3, which is fixedly connected to it, to rotate. By controlling electric actuator 2, the tooth end of gear 5 meshes with the tooth end of rack plate 1, thereby driving the adjusting frame to move back and forth on the moving frame. This, in turn, drives the welding torch and electric grinder to adjust their positions on the worktable, making it convenient to process the workpiece according to its shape, size, or processing requirements. The other gear 4 drives lead screw 2 to rotate, which drives the connecting frame, which is fixedly connected to the moving block, to slide synchronously on the adjusting frame. This allows the welding torch and electric grinder to move vertically up and down on the adjusting frame. It can control the distance between the welding torch and the workpiece according to its shape, size, or processing requirements, ensuring the stability and accuracy of the welding process. At the same time, it also allows the electric grinder to better grind the interface of the workpiece, thereby improving the workpiece's corrosion resistance and conductivity.

[0018] Motor three drives shaft four to rotate, thereby adjusting the processing angle of the welding torch. This allows for flexible adjustment of the torch's posture to meet different welding requirements, optimizing the connection method and improving welding quality. Furthermore, the magnetorheological damper utilizes the rheological properties of the magnetorheological fluid under a magnetic field to adjust the damping force in real time, suppressing vibrations during operation and enhancing the torch's stability. This results in more stable welding of the workpiece, further strengthening the connection's strength and sealing. Simultaneously, electric actuator three moves T-slider three, enabling gear six to mesh with gear seven. This causes the internal gear ring meshing with gear seven to rotate around shaft four, which in turn drives the electric grinder to rotate around shaft four via the connecting plate. This allows for adjustment of the electric grinder's processing angle, further optimizing the grinding position and angle based on the workpiece's shape, size, and processing requirements. This results in a more uniform and ideal grinding effect, enhancing the device's practicality and adaptability.

[0019] This invention provides a grounding dissimilar metal connection device. It has the following advantages:

[0020] 1. This invention uses a clamping structure to hold the workpiece, enhancing processing stability. A moving structure adjusts the left and right positions of the welding torch and the electric grinder, a displacement structure adjusts their left and right positions, and an adjusting structure adjusts their height. The welding torch is used to connect the workpiece, and the electric grinder grinds the interface between the workpiece and the grounding material. This optimizes the connection method based on the shape, size, and processing requirements of the workpiece and the grounding material. Simultaneously, the grinding process improves the corrosion resistance and conductivity of the material, thus solving the problem of limited processing coverage in traditional dissimilar metal connection devices.

[0021] 2. This invention uses motor two to drive shaft one to rotate, and pulleys one and two to rotate belt and lead screw one, thereby adjusting the left and right positions of welding torch and electric grinder on the worktable. Electric push rod one drives gear one to rotate gear two and connecting rod, thereby clamping the workpiece on the worktable with rubber pad and clamping block. This allows the device to easily adjust the position of the processing parts while clamping and fixing the workpiece, improving the automation level and work efficiency of the device, reducing manual operation, and making the entire processing process smoother and more efficient.

[0022] 3. This invention uses a magnetorheological damper to drive two gears (four) to rotate. One gear (four) drives a gear (five) to rotate, which in turn drives a push rod (two) to engage with a rack plate (one). This allows the welding torch and the electric grinder to be adjusted in position on the worktable, facilitating the processing of the workpiece according to its shape, size, or processing requirements. The other gear (four) drives a lead screw (two) to rotate, causing the welding torch and the electric grinder to move vertically up and down on the adjustment frame. This allows the distance between the welding torch and the workpiece to be controlled according to its shape, size, or processing requirements, ensuring the stability and accuracy of the welding process. It also allows the electric grinder to better grind the interface between the workpiece and the grounding material, thereby improving the workpiece's corrosion resistance and conductivity.

[0023] 4. This invention uses motor three to drive shaft four to rotate, thereby flexibly adjusting the welding torch posture according to different welding requirements, optimizing the connection method, improving welding quality, and using a magnetorheological damper to suppress the vibration generated by the welding torch during operation, enhancing the stability of the welding torch, strengthening the connection strength and sealing, and using electric push rod three to enable the tooth tip of gear six to mesh with the tooth tip of gear seven, thereby further optimizing the grinding position and angle of the electric grinder according to the shape and size of the workpiece and processing requirements, making the grinding effect more uniform and ideal, and enhancing the practicality and adaptability of this device.

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] For ease of description, this embodiment describes a dissimilar metal transition connector, comprising section A and section B. Section A is a novel grounding material, such as an aluminum-copper alloy, while section B is a conventional grounding material, such as copper or steel. Sections A and B are connected by compression fitting or welding, and the end of section A closest to section B is sealed. Epoxy resin can be used as the sealing material, and the sealing length is 1-2 meters. During the processing of the dissimilar metal transition connector:

[0037] Please see the appendix Figure 1 -Appendix Figure 10This invention provides a grounding dissimilar metal connection device, including a workbench 1. A clamping structure is provided at the bottom of the workbench 1. A motor 21 is fixedly installed on one side of the workbench 1. A rotating shaft 24 is fixedly installed at the output end of the motor 21. A gear 26 is fixedly connected to the middle of the rotating shaft 24. A movable structure is symmetrically arranged on the outer wall of the rotating shaft 24. A movable frame 5 is fixedly connected to the top of the movable structure. An adjusting frame 13 is slidably connected to the other side of the movable frame 5. A motor 14 is fixedly installed on the top of the adjusting frame 13. A rotating shaft 35 is fixedly installed at the output end of the motor 14. A gear 36 is fixedly connected to the middle of the rotating shaft 35. Gears 4 58 are symmetrically meshed at the tooth ends of gears 36. A displacement structure is provided in the middle of one gear 4 58, and an adjusting structure is provided in the middle of the other gear 4 58. A welding torch 18 is installed on one side of the adjusting structure, and an electric grinder 20 is installed on the other side of the adjusting structure.

[0038] Specifically, the worktable 1 provides a working platform. The clamping structure clamps dissimilar metal workpieces on the worktable 1, enhancing connection stability. Motor 21 drives shaft 24 to rotate, which in turn drives the moving structure, causing the moving frame 5 to move on top of the worktable 1. The moving frame 5 and adjusting frame 13 then move the welding torch 18 and electric grinder 20 left and right on the worktable 1, allowing for easy adjustment of their positions according to workpiece shape, size, or processing requirements. Motor 14 drives shaft 35 to rotate, which in turn drives gear 36, causing two gears 58 to rotate. The displacement structure then moves the adjusting frame 13 back and forth on the moving frame 5, further adjusting the positions of the welding torch 18 and electric grinder 20 on the worktable 1. This facilitates workpiece processing according to workpiece shape, size, or processing requirements. The adjusting structure also drives the welding torch 18 and electric grinder 20. The welding torch 18 moves vertically up and down on the adjusting frame 13, allowing the welding torch 18 to connect and process the workpiece according to its shape, size, or processing requirements. The electric grinder 20 then grinds the interface of the workpiece, improving its corrosion resistance and conductivity. Simultaneously, the operating mechanism adjusts the angle of the electric grinder 20, further adjusting its processing angle based on the workpiece's shape, size, and processing needs, enhancing the device's practicality. The clamping structure holds the workpiece, improving processing stability. The moving structure adjusts the left and right positions of the welding torch 18 and the electric grinder 20, the displacement structure adjusts their left and right positions, and the adjusting structure adjusts their height. The welding torch 18 is used to connect and process the workpiece, while the electric grinder 20 grinds the interface between the workpiece and the grounding material. This optimizes the connection method based on the shape, size, and processing requirements of the workpiece and grounding material, while simultaneously improving the material's corrosion resistance and conductivity through grinding.

[0039] Please see the appendix Figure 1 -Appendix Figure 4The clamping structure includes a connecting rod 6, one end of which is rotatably connected to the bottom of the worktable 1. A rack plate 28 is fixedly connected to one side of the bottom of the worktable 1. A gear 31 is slidably connected to one side of the connecting rod 6. Limiting strips 30 are evenly fixedly connected to one side of the connecting rod 6. The middle part of the gear 31 is slidably connected to the outer wall of the limiting strip 30. Limiting rings 29 are fixedly connected to both ends of the limiting strip 30. The middle part of the limiting rings 29 is fixedly connected to the outer wall of the connecting rod 6. A T-shaped annular groove 32 is provided on one side of the gear 31. A T-shaped slider 33 is slidably connected in the T-shaped annular groove 32 of the gear 31. An electric push rod 27 is fixedly connected to one side of the T-shaped slider 33. One side of the electric push rod 27 is installed at the bottom of the worktable 1. The tooth end of the gear 31 can mesh with the tooth end of the gear 26 or the tooth end of the rack plate 28. The other end of the connecting rod 6 is fixedly connected to a double-ended lead screw. One end of the double-ended lead screw is rotatably connected to the bottom side of the workbench 1. A slide groove 7 is provided in the middle of the workbench 1. A slider 10 is symmetrically threaded on the outer wall of the double-ended lead screw. The outer wall of the slider 10 is slidably connected in the slide groove 7 of the workbench 1. A clamping block 8 is fixedly connected to the top of the slider 10. A rubber pad 9 is installed on the opposite side of the clamping block 8.

[0040] Specifically, the operation of the electric actuator 27 drives the T-shaped slider 33 to move. The T-shaped annular groove 32 then limits the movement of the T-shaped slider 33, causing gear 31 to move along the outer wall of the connecting rod 6 and the limiting strip 30. When workpiece clamping is required, the teeth of gear 31 mesh with the teeth of gear 26, causing gear 26 to rotate. The limiting strip 30 further limits gear 31, causing the connecting rod 6 to rotate, which in turn rotates the bidirectional lead screw on the worktable 1. This allows the two sliders 10 to move on the worktable 1. The workpiece moves closer to or further away from each other within the sliding groove 7, thereby clamping the workpiece using the rubber pad 9 and the clamping block 8. After clamping, the electric push rod 27 drives the gear 31 to move, causing the tooth end of the gear 31 to mesh with the tooth end of the rack plate 28, thereby disengaging from the tooth end of the gear 26. The tooth end of the rack plate 28 limits the gear 31, preventing it from rotating. This keeps the positions of the rubber pad 9 and the slider 10 fixed, achieving stable clamping of the workpiece. This effectively enhances the stability of the workpiece during welding and avoids affecting the welding quality due to workpiece shaking.

[0041] Please see the appendix Figure 1 -Appendix Figure 4The moving structure includes a pulley 25, the middle of which is fixedly connected to the outer wall of the rotating shaft 24. A pulley 22 is connected to one side of the pulley 25, and a belt 23 is connected to one side of the pulley 22. The middle of the belt 23 is fixedly connected to one side of the lead screw 3. The two ends of the lead screw 3 are rotatably connected to the bottom side of the worktable 1. The top of the worktable 1 is symmetrically provided with a slide groove 2. A slider 4 is threadedly connected to the outer wall of the lead screw 3. The outer wall of the slider 4 is slidably connected in the slide groove 2 of the worktable 1. The top of the slider 4 is fixedly connected to the bottom of the moving frame 5.

[0042] Specifically, when motor 21 operates, it drives shaft 24 to rotate, which in turn drives two pulleys 25 to rotate. These pulleys, in turn, drive belt 23 to rotate, which in turn drives lead screw 3 to rotate. This causes slider 4 to slide within groove 2 of worktable 1, thereby moving the moving frame 5 on worktable 1. This allows the welding torch 18 and electric grinder 20 to be adjusted left and right on worktable 1 according to the shape, size, or processing requirements of the workpiece, facilitating workpiece processing. Thus, it achieves the goal of driving shaft 24 solely through the operation of motor 21. The rotation of pulley 24 causes belt 23 and lead screw 3 to rotate via pulley 25 and pulley 22, thereby adjusting the left and right positions of welding torch 18 and electric grinder 20 on worktable 1. The electric push rod 27 causes gear 26 to drive gear 31 and connecting rod 6 to rotate, thereby causing rubber pad 9 and clamping block 8 to clamp the workpiece on worktable 1. This allows the device to conveniently adjust the position of the processing parts while clamping and fixing the workpiece, improving the automation level and work efficiency of the device, reducing manual operation, and making the entire processing process smoother and more efficient.

[0043] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 5 -Appendix Figure 7The displacement structure includes a rotating shaft 40, one side of which is fixedly connected to the middle of one of the gears 58. Limiting strips 44 are uniformly fixedly connected to the outer wall of the rotating shaft 40. Limiting rings 43 are fixedly connected to both ends of the limiting strips 44. The middle of the limiting rings 43 is fixedly connected to the outer wall of the rotating shaft 40. Gears 41 are slidably connected to both the outer wall of the rotating shaft 40 and the outer wall of the limiting strips 44. A T-shaped annular groove 45 is provided on one side of the gears 41. The two ends of the rotating shaft 40 are rotatably connected to the inside of the adjusting frame 13. An electric push rod 42 is installed on one side of the inside of the adjusting frame 13. The output end of the electric push rod 42 is fixedly connected to a T-shaped slider 46. The outer wall of the T-shaped slider 46 is slidably connected to the T-shaped annular groove 45 of the gear 5. A T-shaped slider 34 is symmetrically fixedly connected to one side of the adjusting frame 13. The outer wall of the T-shaped slider 34 is slidably connected to the T-shaped groove 11 of the moving frame 5. A rack plate 12 is fixedly connected to one side of the moving frame 5. The tooth end of the gear 5 41 can mesh with the tooth end of the rack plate 12.

[0044] Specifically, the rotation of one of the gears, 58, drives the rotating shaft 40, which is fixedly connected to it, to rotate. Since the outer wall of the rotating shaft 40 is uniformly and fixedly connected with limiting strips 44, and these limiting strips 44 provide circumferential limiting for the gear 41, the rotation of the rotating shaft 40 will cause the gear 41 to rotate synchronously. At this time, if it is necessary to adjust the front and rear positions of the welding torch 18 and the electric grinder 20, the operation of the electric push rod 42 can be controlled to drive the T-shaped slider 46 to move linearly. Since the outer wall of the T-shaped slider 46 is slidably connected within the T-shaped annular groove 45 of the gear 41, the limiting effect of the T-shaped annular groove 45 on the T-shaped slider 46 allows the gear 41 to maintain synchronous rotation with the rotating shaft 40 while moving with the T-shaped slider 46. Ultimately, this achieves axial movement of the gear 41 on the outer wall of the rotating shaft 40 and the limiting strip 44 until the tooth end of the gear 41 meshes with the tooth end of the rack plate 12. When gear 5 41 meshes with rack plate 1 12, as shaft 3 40 continues to rotate, gear 5 41 rolls along rack plate 1 12, thereby driving the T-shaped slider 34 on the adjusting frame 13 to slide within the T-shaped groove 11 of the moving frame 5. This allows the adjusting frame 13 to move back and forth on the moving frame 5, which in turn drives the welding torch 18 and the electric grinder 20 to adjust their positions on the worktable 1. This facilitates the processing of the workpiece according to its shape, size, or processing requirements. Simultaneously, the mating structure of the T-shaped slider 34 and the T-shaped groove 11 not only provides stable sliding support for the adjusting frame 13 but also effectively prevents the adjusting frame 13 from shifting or wobbling during movement, further improving the stability and reliability of the processing.

[0045] Please see the appendix Figure 1 Appendix Figure 2 AppendixFigure 5 Appendix Figure 6 Appendix Figure 8 -Appendix Figure 10 The adjusting structure includes a lead screw 15, one side of which is fixedly connected to the middle of another gear 58.

The outer wall of the moving block 16 is slidably connected to one side of the inside of the adjusting frame 13. A connecting frame 17 is fixedly connected to one side of the moving block 16. A motor 47 is fixedly installed on one side of the inside of the connecting frame 17. A rotating shaft 49 is fixedly installed at the output end of the motor 47. Limiting strips 55 are evenly fixedly connected to the outer wall of the rotating shaft 49. Limiting rings 54 are fixedly connected to both ends of the limiting strips 55. The middle of the limiting rings 54 is fixedly connected to one side of the outer wall of the rotating shaft 49. Gears 50 are slidably connected to both the outer wall of the rotating shaft 49 and the outer wall of the limiting strips 55. A T-shaped annular groove 3 57 is provided on one side of gear 6 50. A T-shaped slider 3 56 is slidably connected in the T-shaped annular groove 3 57 of gear 6 50. An electric push rod 3 53 is fixedly connected to one side of the T-shaped slider 3 56. One side of the electric push rod 3 53 is installed inside the connecting frame 17. A rotating shaft 5 52 is evenly fixedly connected inside the connecting frame 17. A gear 7 51 is rotatably connected to the outer wall of the rotating shaft 5 52. The tooth end of gear 6 50 can mesh with the tooth end of gear 7 51. An internal gear ring 48 is meshed with the tooth end of gear 7 51. A connecting plate 19 is fixedly connected to the outer wall of the internal gear ring 48. An electric grinder 20 is installed on one side of the connecting plate 19. One side of the outer wall of the rotating shaft 49 is rotatably connected to one side of the connecting frame 17. One end of the rotating shaft 49 is fixedly connected to the connecting plate 37. Magnetorheological dampers 38 are evenly installed on one side of the connecting plate 37. A rotating plate 39 is installed on one side of the magnetorheological damper 38. A welding torch 18 is installed on one side of the rotating plate 39.

[0046] Specifically, when motor 38 drives shaft 39 to rotate, the meshing of gear 47 and gear 58 causes gear 58 to rotate, which in turn drives lead screw 15, which is fixedly connected to it, to rotate. Since the outer wall of lead screw 15 is threaded with a moving block 16, and the outer wall of moving block 16 is slidably connected to the inside of the adjusting frame 13, when lead screw 15 rotates, it will drive moving block 16 to slide linearly on the adjusting frame 13, thereby driving the connecting frame 17, which is fixedly connected to moving block 16, to slide synchronously on the adjusting frame 13. The sliding of the connecting frame 17 drives the welding torch 18 to move up and down on the adjusting frame 13 via the connecting plate 37, the magnetorheological damper 38, and the rotating plate 39. At the same time, the electric grinder 20 is driven to move up and down via the gear 7 51, the rotating shaft 52, the internal gear ring 48, and the connecting plate 19. This enables the welding torch 18 and the electric grinder 20 to move vertically up and down on the adjusting frame 13. The distance between the welding torch 18 and the workpiece can be controlled according to the shape and size of the workpiece or the processing requirements, ensuring the stability and accuracy of the welding process. At the same time, it also allows the electric grinder 20 to better grind the interface between the workpiece and the grounding material, thereby improving the corrosion resistance and conductivity of the workpiece and the grounding material.

[0047] When the machining angle of the welding torch 18 needs to be adjusted, the operation of motor 3 47 drives the rotating shaft 49 to rotate, which in turn drives the connecting plate 37 to rotate on the connecting frame 17. This, combined with the magnetorheological damper 38 and the rotating disk 39, causes the welding torch 18 to rotate around the rotating disk 39, thus adjusting the machining angle of the welding torch 18. This allows for flexible adjustment of the welding torch 18's posture according to different welding requirements, optimizing the connection method and improving welding quality. Simultaneously, during welding torch 18 operation, the operation of the magnetorheological damper 38 utilizes the rheological properties of its internal magnetorheological fluid under the influence of a magnetic field to adjust the damping force in real time, effectively suppressing vibrations generated by the welding torch 18 during operation, enhancing the stability of the welding torch 18, and thus enabling the welding torch 18 to weld the workpiece more stably, further strengthening the connection strength and sealing.

[0048] When the processing angle of the electric grinder 20 needs to be adjusted, the limiting strip 3 55 limits the gear 6 50, and the rotating shaft 49 drives the gear 6 50 to rotate. At the same time, the operation of the electric push rod 3 53 drives the T-shaped slider 3 56 to move. Since the outer wall of the T-shaped slider 3 56 is slidably connected in the T-shaped annular groove 3 57 of the gear 6 50, the limiting effect of the T-shaped annular groove 3 57 on the T-shaped slider 3 56 allows the gear 6 50 to maintain synchronous rotation with the rotating shaft 49 while moving with the T-shaped slider 3 56. Finally, the gear 6 50 slides axially on the rotating shaft 49 and the limiting strip 3 55, so that the tooth end of the gear 6 50 can mesh with the tooth end of the gear 7 51. When gear 6 50 meshes with gear 7 51, the rotation of gear 6 50 will drive gear 7 51 to rotate on shaft 5 52, which in turn will drive the internal gear ring 48 meshing with gear 7 51 to rotate around shaft 49. This will drive the electric grinder 20 to rotate around shaft 49 via connecting plate 19, thereby adjusting the processing angle of the electric grinder 20. This allows for further optimization of the grinding position and angle of the electric grinder 20 according to the shape and size of the workpiece and the grounding material and the processing requirements, resulting in a more uniform and ideal grinding effect, and enhancing the practicality and adaptability of the device.
