Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and in particular to a laser welding and rolling aluminum profile connection device. Background Technology

[0002] Aluminum profile processing refers to the process of using aluminum and aluminum alloys as raw materials and processing them into products with specific shapes, sizes, and properties through a series of processes. Aluminum profile processing typically includes major steps such as smelting and casting, extrusion, and surface treatment. First, high-purity aluminum ingots and alloying elements added according to the product performance requirements are put into a furnace for smelting to obtain an aluminum alloy melt with the required composition and temperature. Then, ingots are made through a casting process. After the ingots are heated to a certain temperature, they are placed in an extrusion press. Under strong pressure, the aluminum alloy ingots are extruded from the die holes to form aluminum profiles with specific cross-sectional shapes and sizes. Finally, in order to improve the corrosion resistance, wear resistance, and decorative properties of aluminum profiles, surface treatment is performed. Common surface treatment methods include anodizing, electrophoretic coating, and powder coating. After these processing steps, aluminum profiles can be widely used in many fields such as construction, automobiles, aerospace, and electronics.

[0003] During aluminum profile processing, sometimes aluminum profiles are welded and then rolled according to product requirements to make the weld seam denser and improve the strength and sealing of the weld seam. However, when the existing equipment is used for welding and rolling aluminum profiles, the staff needs to make repeated adjustments to align the axes of the two aluminum profiles, which greatly affects the work efficiency.

[0004] Therefore, we propose a laser welding device for connecting rolled aluminum profiles to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A laser welding device for connecting rolled aluminum profiles includes a worktable for connecting rolled aluminum profiles by laser welding. The top of the worktable has two centering grooves, and centering bases are fixedly installed on the bottom inner walls of the two centering grooves. Centering mechanisms are provided on the inner sides of the two centering bases. The top of the worktable also has two flipping bases, on which aluminum profiles are placed. Flipping mechanisms are provided on the inner sides of the two flipping bases.

[0007] Specifically, a robotic arm is fixedly installed on one side of the workbench, and the main body of the laser welder is mounted on the robotic arm.

[0008] Specifically, the flipping mechanism includes two rollers and two servo motors. The top of the flipping base has two rotating slots, and rollers are rotatably installed on the inner side of each of the two rotating slots. The interior of the flipping base has two motor slots, and servo motors are fixedly installed on the inner wall of one side of each of the two motor slots. The output shafts of the two servo motors are respectively fixedly connected to the corresponding rollers, so that the rollers can be driven to rotate by the servo motors, thereby driving the aluminum profile to rotate.

[0009] Specifically, extrusion cylinders are fixedly installed on the bottom inner walls of the two centering tanks, and extrusion metal blocks are fixedly installed on the output ends of the two extrusion cylinders. The two extrusion metal blocks are in contact with one end of the corresponding aluminum profile, so that the corresponding aluminum profile can be moved by the two extrusion metal blocks.

[0010] Specifically, triangular metal blocks are slidably installed on the bottom inner walls of the two centering grooves, and a linkage protrusion is provided on one side of each of the two triangular metal blocks. Centering cylinders are fixedly installed on the bottom inner walls of the two centering grooves, and the output ends of the two centering cylinders are fixedly connected to one side of the corresponding triangular metal blocks, so as to facilitate the movement of the triangular metal blocks by driving the centering cylinders.

[0011] Specifically, the alignment mechanism includes four guide metal blocks, four alignment metal blocks, four linkage bars, and four clamps. The alignment base has four guide grooves on one side, and guide metal blocks are slidably installed on the inner side of each of the four guide grooves. Alignment metal blocks are fixedly installed on one side of each of the four guide metal blocks. Each of the four alignment metal blocks has two linkage holes on one side, and corresponding linkage bars are slidably installed on the inner side of each of the linkage holes. Clamps are fixedly installed on one side of each of the four alignment metal blocks to facilitate alignment of the aluminum profile axis using the four clamps.

[0012] Specifically, the surfaces of the four clips are coated with polytetrafluoroethylene (PTFE). Since the PTFE coating has low friction, it will not affect the rotation of the aluminum profile.

[0013] Specifically, a linkage groove is provided on one side of the centering metal block closest to the centering cylinder among the four centering metal blocks. The linkage groove is adapted to the linkage protrusion, so as to facilitate the movement of the corresponding centering metal block by the triangular metal block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the centering mechanism can make the axes of the two aluminum profiles aligned, eliminating the need for long-term manual adjustment by the staff, which greatly improves work efficiency. At the same time, the flipping mechanism can assist the aluminum profiles in rotating during welding, which improves the practicality of the equipment. Attached Figure Description

[0021] Reference Figure 1-5 A laser welding rolled aluminum profile connection device includes a worktable 1 for laser welding rolled aluminum profile connection. The top of the worktable 1 has two centering grooves. Centering bases 10 are fixedly installed on the bottom inner walls of the two centering grooves. Centering mechanisms are provided on the inner sides of the two centering bases 10. The top of the worktable 1 has two flipping bases 4. Aluminum profiles 7 are placed on the two flipping bases 4. Flipping mechanisms are provided on the inner sides of the two flipping bases 4.

[0022] In this embodiment, a robotic arm 2 is fixedly installed on one side of the workbench 1, and a laser welder body 3 is provided on the robotic arm 2.

[0023] In this embodiment, the flipping mechanism includes two rollers 5 and two servo motors 6. The top of the flipping base 4 has two rotating slots, and rollers 5 are rotatably installed on the inner side of each of the two rotating slots. The interior of the flipping base 4 has two motor slots, and servo motors 6 are fixedly installed on the inner wall of one side of each of the two motor slots. The output shafts of the two servo motors 6 are respectively fixedly connected to the corresponding rollers 5, so that the rollers 5 can be rotated by the servo motors 6, thereby driving the aluminum profile 7 to rotate.

[0024] In this embodiment, extrusion cylinders 8 are fixedly installed on the bottom inner walls of the two centering grooves, and extrusion metal blocks 9 are fixedly installed on the output ends of the two extrusion cylinders 8. The two extrusion metal blocks 9 are respectively in contact with one end of the corresponding aluminum profile 7, so that the corresponding aluminum profile 7 can be moved by the two extrusion metal blocks 9.

[0025] In this embodiment, triangular metal blocks 16 are slidably installed on the bottom inner walls of the two centering grooves. Each of the two triangular metal blocks 16 has a linkage protrusion on one side. Centering cylinders 17 are fixedly installed on the bottom inner walls of the two centering grooves. The output ends of the two centering cylinders 17 are fixedly connected to one side of the corresponding triangular metal blocks 16, so as to facilitate the movement of the triangular metal blocks 16 by the centering cylinders 17.

[0026] In this embodiment, the centering mechanism includes four guide metal blocks 11, four centering metal blocks 12, four linkage bars 14, and four clamps 15. Four guide grooves are provided on one side of the centering base 10. Guide metal blocks 11 are slidably installed on the inner side of each of the four guide grooves. Centering metal blocks 12 are fixedly installed on one side of each of the four guide metal blocks 11. Two linkage holes 13 are provided on one side of each of the four centering metal blocks 12. Corresponding linkage bars 14 are slidably installed on the inner side of each of the multiple linkage holes 13. Clamps 15 are fixedly installed on one side of each of the four centering metal blocks 12 to facilitate the alignment of the axis of the aluminum profile 7 by means of the four clamps 15.

[0027] In this embodiment, the surfaces of the four clips 15 are all coated with polytetrafluoroethylene (PTFE). Since the PTFE coating has low friction, it will not affect the rotation of the aluminum profile 7.

[0028] In this embodiment, a linkage groove is provided on one side of the centering metal block 12 closest to the centering cylinder 17 among the four centering metal blocks 12. The linkage groove is adapted to the linkage protrusion, so that the corresponding centering metal block 12 can be moved by the triangular metal block 16.

[0029] Working principle: When welding aluminum profiles 7, the operator first places two aluminum profiles 7 on their respective flipping bases 4. Then, the two centering cylinders 17 are activated. The activation of the centering cylinders 17 drives the triangular metal block 16 to move. One side of the triangular metal block 16 has a linkage protrusion, and the side of the centering metal block 12 that contacts the triangular metal block 16 has a linkage groove. The linkage protrusion and the linkage groove are matched. Therefore, when the triangular metal block 16 moves, the centering metal block 12 that contacts it moves. The movement of the centering metal block 12 drives the two linkage bars 14 to move. The two linkage bars 14 drive the corresponding centering metal block 12 to move through the corresponding linkage holes 13. The movement of the two centering metal blocks 12 drives the other two linkage bars 14 to move. At this time, the movement of the two linkage bars 14 drives the same centering metal block 12. Block 12 moves, and the four centering metal blocks 12 move closer to each other, causing the corresponding clamps 15 to move closer to each other to center and clamp the aluminum profile 7. After the two centering mechanisms center and clamp the corresponding aluminum profile 7, the operator starts two extrusion cylinders 8. The two extrusion cylinders 8 drive the corresponding extrusion metal blocks 9 to move and extrude the corresponding aluminum profile 7, making the connection between the two aluminum profiles 7 tighter. Then, laser welding is performed on the gap between the two aluminum profiles 7. After the designated area is welded, the operator starts four servo motors 6. The four servo motors 6 start and drive the corresponding rollers 5 to rotate. Since the surfaces of multiple clamps 15 are coated with polytetrafluoroethylene, the friction is small and will not affect the rotation of the aluminum profile 7. Therefore, the rotation of the four rollers 5 drives the aluminum profile 7 to rotate, which facilitates the welding of the unwelded areas.

[0030] The technological advancements of this invention compared to existing technologies are: it allows the axes of the two aluminum profiles 7 to be aligned, eliminating the need for long-term manual adjustments by workers and greatly improving work efficiency; at the same time, the included flipping mechanism can assist the aluminum profiles 7 in rotating during welding, enhancing the practicality of the equipment.
