For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0048] Reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, proposes a welding device for radiator production, which is used to weld the welding joints 2 on two adjacent radiators 1 together, including: a receiving frame 4 is lifted and arranged on a base frame 3, and the receiving frame 4 has a through hole 5, and the receiving frame 4 is used to support the radiator 1; a positioning shaft 6 is arranged on the base frame 3, and the positioning shaft 6 passes through the through hole 5. When the radiator 1 is installed on the receiving frame 4, the positioning shaft 6 passes through the welding joint 2; a welding piece 7 is rotatably arranged on the base frame 3, and when the receiving frame 4 is lifted and lowered, it approaches or moves away from the welding piece 7, and the welding piece 7 is used to weld the welding joint 2.

[0049] In this embodiment, when in use, first slide the receiving frame 4 upward to a suitable position, then place the radiator 1 to be welded on the bearing frame, and the positioning shaft 6 can pass through the radiator 1 for auxiliary positioning to ensure that the installation position of the radiator 1 will not deviate. After installation, adjust the position of the receiving frame 4 again to expose the inner wall of the welding port 2 to be welded, and make it located on the welding head of the welding piece 7. The welding head will rotate while working, so that the inner wall of the welding port 2 is completely welded, ensuring the quality and speed of welding. The setting of the positioning shaft 6 ensures the position accuracy of the radiator 1 during the welding process. When the radiator 1 is installed on the receiving frame 4, the positioning shaft 6 passes through the welding port 2, which can effectively prevent the radiator 1 from being displaced during welding, thereby greatly improving the welding accuracy and making the connection between two adjacent radiators 1 more firm and reliable. The through hole 5 on the receiving frame 4 cooperates with the positioning shaft 6 to provide stable support and positioning for the radiator 1, making the welding process more stable and reducing welding defects caused by factors such as shaking. The design of the positioning shaft 6 and the receiving frame 4 makes the installation and positioning of the radiator 1 faster and more convenient, shortens the preparation time before welding, and further improves the production efficiency.

[0050] As a further technical solution, the positioning shaft 6 is rotatably set on the base frame 3, and the positioning shaft 6 has a plurality of accommodating cavities 8, and also includes: there are a plurality of grinding blocks 9, one end of the grinding block 9 is rotatably set in the accommodating cavity 8, after the grinding block 9 rotates, the grinding block 9 leaves the accommodating cavity 8 and abuts against the inner wall of the welding port 2; the two ends of the first elastic member 10 are respectively set on the positioning shaft 6 and the grinding block 9, and the first elastic member 10 is used to provide force for the grinding block 9 to enter the accommodating cavity 8.

[0051] In this embodiment, after welding is completed, there will be welding slag or uneven welds at the weld, which will cause the water quality inside the heater to be dirty when in use, affecting the life of the boiler. The setting of the grinding block 9 can grind the inner wall of the welding port 2 after welding, remove impurities such as welding slag on the inner wall, and make the welding part cleaner, thereby significantly improving the user experience and enhancing the firmness and sealing of the welding. The first elastic member 10 can ensure that the grinding block 9 is reliably stored in the accommodating chamber 8 when not in use to avoid interference with other components. When the positioning shaft 6 rotates, the grinding block 9 will overcome the elastic force of the first elastic member 10 under the action of centrifugal force and closely abut against the inner wall of the welding port 2 to ensure the grinding effect. The operator only needs to control the rotation of the positioning shaft 6 and the lifting and lowering of the receiving frame 4 to complete the entire welding and grinding process, reducing the difficulty of operation.

[0052] As a further technical solution, it also includes: an upper cover body 11 and a lower cover body 12 are arranged on the positioning shaft 6, located on the upper and lower sides of the grinding block 9, and after the upper cover body 11 and the lower cover body 12 enter the welding port 2, the upper cover body 11, the lower cover body 12 and the welding port 2 form a cleaning space.

[0053] In this embodiment, the upper cover 11 and the lower cover 12 together with the radiator 1 form a cleaning space, which can effectively prevent the iron filings and welding slag generated by the grinding block 9 from splashing. This greatly reduces the risk of operators being injured by splashing objects and provides a safer working environment for the production site. The setting of the cleaning space limits the iron filings and welding slag generated by grinding to a certain range, which is convenient for centralized cleaning. It avoids the iron filings and welding slag from being scattered everywhere, keeps the production site clean, and reduces the difficulty and time cost of subsequent cleaning work. At the same time, the cleaning space can also prevent iron filings from entering the interior of the radiator 1 during grinding, further improving the quality of the product.

[0054] As a further technical solution, the upper cover body 11 is composed of a plurality of arc plates 14, which are rotatably set on the positioning shaft 6, and also includes: a limit block 15 is set on the positioning shaft 6, and the limit block 15 is used to limit the rotation angle of the arc plate 14; the two ends of the second elastic member 16 are respectively set on the positioning shaft 6 and the arc plate 14, and the second elastic member 16 is used to provide a force for the arc plate 14 to approach the limit block 15.

[0055] In this embodiment, the upper cover body 11 itself is composed of multiple arc plates 14. When the welding of the welding port 2 is completed, the inner diameter of the welding port 2 is small, so it is easy to get the upper cover body 11 stuck. The upper cover body 11 composed of multiple arc plates 14 will be driven by the weld to rotate when it hits the weld, and will not get stuck. When the upper cover body 11 completely passes through the weld, the arc plate 14 will be reset under the action of the second elastic member 16 to ensure that the cleaning space is relatively closed. When rotating at high speed, the limit block 15 will also ensure that the arc plate 14 will not directly hit the inner wall of the welding port 2 even under the action of strong centrifugal force, thereby protecting the safety of the upper cover body 11. At the same time, the upper cover body 11 can rotate at high speed during grinding, and can also effectively prevent large pieces of welding slag from flying out of the gaps between the arc plates 14, thereby ensuring the relative safety of the upper cover body 11.

[0056] As a further technical solution, the positioning shaft 6 is provided with a plurality of chip removal channels 17 , the cleaning space, the accommodating chamber 8 and the chip removal channels 17 are connected in sequence, and the chip removal channels 17 run through the bottom of the positioning shaft 6 .

[0057] In this embodiment, a plurality of chip removal channels 17 are provided on the positioning shaft 6, and the cleaning space, the accommodating chamber 8 and the chip removal channels 17 are connected in sequence, so that the iron filings and welding slag generated by grinding can be quickly discharged through the chip removal channels 17. It avoids the accumulation of iron filings and welding slag in the cleaning space and the accommodating chamber 8, which affects the grinding and welding effects, and improves production efficiency. The chip removal channel 17 runs through the positioning shaft 6 and is connected at the lower end, which is convenient for the centralized discharge of iron filings and welding slag. It can be connected to an external collection device to realize automatic cleaning, reducing the workload and time cost of manual cleaning. Timely discharge of iron filings and welding slag can keep the interior of the equipment clean and reduce the wear and damage to equipment parts caused by the accumulation of impurities. It extends the service life of the equipment and reduces the maintenance cost of the equipment.

[0058] As a further technical solution, it also includes: the collecting bucket 30 is detachably arranged on the base frame 3, and the collecting bucket 30 is located below the chip removal channel 17.

[0059] In this embodiment, the collecting bucket 30 is detachably arranged on the base frame 3. When the welding slag and iron filings in the collecting bucket 30 accumulate to a certain extent, it can be easily removed for cleaning. The operation is simple and quick, which greatly reduces the difficulty and time cost of cleaning work. This detachable design makes the maintenance of the equipment more convenient. The collecting bucket 30 can be checked and cleaned regularly to ensure its normal operation, and it is also convenient for maintenance and overhaul of other parts of the equipment. The collecting bucket 30 is located below the positioning shaft 6, and can accurately collect the welding slag and iron filings discharged from the chip discharge channel 17, preventing these impurities from scattering in the working area, and keeping the working environment clean. A clean working environment not only improves work efficiency, but also reduces safety hazards that may be caused by the accumulation of impurities.

[0060] As a further technical solution, it also includes: there are several sliding sleeves 18, which are slidably set on the supporting frame 4, the through hole 5 and the positioning shaft 6 are both set on the base frame 3 through the sliding sleeves 18, and the radiator 1 is set on the supporting frame 4 through the sliding sleeves 18, and the sliding sleeves 18 slide close to or away from the supporting frame 4.

[0061] In this embodiment, the design of the sliding sleeve 18 allows the radiator to be removed more quickly and conveniently after all the radiators 1 are welded, completing the overall welding steps and achieving continuous production. At the same time, when the equipment needs to be maintained and repaired, the positioning shaft 6 can be slid to a suitable position, making it convenient for operators to inspect and repair the positioning shaft 6, the sliding sleeve 18 and other related components. The efficiency of equipment maintenance is improved and the maintenance cost is reduced.

[0062] As a further technical solution, it also includes: a first telescopic member 19 is arranged on the receiving frame 4, the first telescopic member 19 has a first telescopic end 20, the first telescopic end 20 is arranged on the sliding sleeve 18, and the first telescopic member 19 is used to drive the sliding sleeve 18 to slide.

[0063] In this embodiment, the setting of the first telescopic member 19 enables the sliding of the sliding sleeve 18 to be automatically controlled. No manual operation is required, which greatly improves the operating efficiency of the equipment. The operator can easily adjust the position of the sliding sleeve 18 by controlling the first telescopic member 19, saving time and labor costs. Automated sliding control can achieve more precise position adjustment, ensure that the positioning shaft 6 and the welding port 2 of the radiator 1 are accurately matched, and improve the welding quality and accuracy. The first telescopic member 19 can provide a stable thrust or pull force to make the sliding sleeve 18 more stable during the sliding process. It avoids the unstable factors that may be caused by manual operation and reduces the impact on welding quality.

[0065] In this embodiment, the first rotating driving member 23 drives the receiving frame 4 to move up and down through the chain 21 , the first sprocket 22 and the second sprocket 25 , so as to achieve precise control of the height of the receiving frame 4 .

[0066] As a further technical solution, it also includes: a first gear 26 is arranged on the positioning shaft 6; a second rotating driving member 27 is arranged on the sliding sleeve 18, and the second rotating driving member 27 has a second output end 28; a second gear 29 is arranged on the second output end 28, the second gear 29 is meshed with the first gear 26, and the second rotating driving member 27 is used to drive the positioning shaft 6 to rotate.

[0067] In this embodiment, the second rotating driving member 27 drives the positioning shaft 6 to rotate by meshing with the first gear 26 through the second gear 29, and can realize precise control of the rotation of the positioning shaft 6. The rotation speed and direction of the positioning shaft 6 can be adjusted according to different grinding and welding requirements to improve the processing accuracy and quality.
