[0002] Aluminum alloy welding refers to the process of welding aluminum alloy materials. Aluminum alloys are high in strength and light in weight. The main welding processes are manual MIG welding (metal inert gas welding) and automatic MIG welding. The base material, welding wire, shielding gas, and welding equipment are all important. After welding, existing aluminum alloy pipes often have impurities on the outer surface of the weld, which requires grinding equipment to polish the weld.
[0003] The existing method for grinding aluminum alloy welds generally involves workers using a grinder to grind the weld. During grinding, the pipe needs to be fixed. Because the pipe needs to be ground from multiple angles, it needs to be repeatedly loosened and fixed, which affects the installation efficiency.

[0034] In this embodiment, the user places two aluminum alloy pipes outside multiple limiting blocks 10, moves the top plate 15 to adjust the grinding position, and finally controls the first motor 11 and the second motor 16 to work. The first motor 11 rotates the first shaft 8 and the first sprocket 22. The rotation of the first sprocket 22 drives the second sprocket 23 and the second shaft 9 to rotate.

[0037] At the same time, pull the top plate 15, and the top plate 15 moves upward, causing multiple positioning blocks 27 to disengage from the corresponding positioning grooves 14, so that the movable block 28 is embedded in the movable groove 13, and the top plate 15 is moved to adjust the grinding position.
[0038] To achieve the purpose of cooling, the device adopts the following technical solution: The cooling mechanism includes two water pumps 30, both of which are embedded inside the water tank 3. The output ends of both water pumps 30 extend to the outside of both sides of the water tank 3. The output ends of both water pumps 30 are fixedly connected to drain pipes 31. Two hoses 32 are fixedly connected to the inside of both drain pipes 31. Two connecting plates 33 are fixedly connected to the outside of both side plates 29. Connecting pipes 34 are embedded inside the multiple connecting plates 33. The two ends of the two connecting pipes 34 are fixedly connected to the top of the multiple hoses 32 respectively. The bottom of the two connecting pipes 34 are fixedly connected to spray pipes 35.
[0039] In addition, during the polishing process, two water pumps 30 are started to work. The two water pumps 30 draw water out of their internal parts, so that the cooling water is sprayed out through two water sprayers to cool the polished area. The cooling water falls into the water tank 3. The water pumps 30 enable the cooling water to be recycled, which greatly reduces the waste of water resources, reduces cost losses, and brings greater benefits to the producer.
[0040] To achieve the positioning purpose, the device adopts the following technical solution: partitions 36 are fixedly embedded inside the two tracks 4, slide rods 37 are fixedly connected to both sides of the two partitions 36, multiple slide rods 37 are respectively embedded inside multiple sliders 5, first springs 38 are fixedly connected to the inner side of multiple sliders 5, multiple first springs 38 are respectively sleeved on the outer side of multiple slide rods 37, and second springs 39 are fixedly sleeved on the outer side of the two telescopic rods 20.
[0041] This device employs a design with a first spring 38 and a second spring 39, ensuring that the grinding disc 21 is always in close contact with the weld joint of the two pipes. This allows the grinding disc 21 to always grind the weld joint without needing to flip the pipes over, thus reducing grinding time and increasing grinding efficiency.
[0042] To achieve the connection, the device employs the following technical solution: the first rotating shaft 8 and the second rotating shaft 9 are both movably connected to the vertical plate 7 via rolling bearings; the first rotating rod 17 and the second rotating rod 18 are both movably connected to the top plate 15 via rolling bearings; two handles 40 are fixedly connected to the top of the top plate 15; and a water inlet pipe 41 is fixedly connected to the front side of the water tank 3.
[0043] The usage process of this invention is as follows: The user places two aluminum alloy pipes outside multiple limiting blocks 10, and simultaneously pulls the top plate 15. The top plate 15 moves upward, causing multiple positioning blocks 27 to disengage from their corresponding positioning slots 14, allowing the movable block 28 to embed into the movable slot 13. The top plate 15 is moved to adjust the grinding position. Finally, the first motor 11 and the second motor 16 are controlled to operate. The first motor 11 operates, causing the first rotating shaft 8 and the first sprocket 22 to rotate. The rotation of the first sprocket 22 drives the second sprocket 23 and the second rotating shaft 9 to rotate. The rotation of the first rotating shaft 8 and the second rotating shaft 9 drives the multiple limiting blocks 10 to rotate, thereby causing the two pipes to rotate. The second motor 16 operates, driving the first rotating rod 17 and the third sprocket 25 to rotate. The rotation of the third sprocket 25 drives the fourth sprocket 26 and the second rotating rod 18 to rotate. The first rotating rod 17... The rotation of the second rotating rod 18 drives the two telescopic rods 20 and the grinding disc 21 to rotate. The two grinding discs 21 perform uniform welding treatment on the welded joints of the two pipes. The device adopts the design of the first spring 38 and the second spring 39, which makes the grinding disc 21 always close to the welded joints of the two pipes, so that the grinding disc 21 can always grind the welded joints without the need to flip the pipes, thus reducing grinding time and increasing grinding efficiency. In addition, during the grinding process, the two water pumps 30 are started to work. The two water pumps 30 draw water from their internal parts, so that cooling water is sprayed out through two water sprayers to cool the ground area. The cooling water falls into the water tank 3, and the water pumps 30 enable the cooling water to be recycled, which greatly reduces water waste, reduces cost losses, and brings greater benefits to the producer.
