[0002] Industries such as rail transit, automobile manufacturing, and power electronics usually generate a lot of heat during operation. The generation of heat has an adverse effect on the production and use of parts and electronic components, reducing the service life of parts and reducing production efficiency. Therefore, heat dissipation devices are usually required in parts that generate a lot of heat and are sensitive to temperature. At present, the materials of heat dissipation devices include copper, stainless steel, etc. Aluminum alloys are also used as the main material for the manufacture of heat dissipation devices because of their good heat dissipation and processability. At present, aluminum alloy radiators are mainly divided into sunflower, flat, plate-fin, etc. according to their shape classification. The main means of production and manufacturing are casting and brazing, but the assembly and manufacturing of large-sized aluminum alloy sealed radiators cannot be achieved through casting or the cost is too high and the precision is low. The brazing strength cannot meet the pressure conditions of large-sized aluminum alloy sealed radiators, so melting welding and other welding methods have become important processing methods for the production and manufacturing of large aluminum alloy sealed radiators. In the welding process, welding tooling is an important tool device to ensure the quality of welding. At present, there are few designs for aluminum alloy sealed radiator tooling, and the degree of automation of the tooling used is low. With the development of automation, automation equipment will be widely used in the production and manufacturing of radiators.

[0025] An upper clamping device for clamping the radiator 11 is provided at the top of the radiator mounting hole 4, and the upper clamping device cooperates with the pneumatic support mechanism 9 to vertically fix the radiator 11;

[0026] A pneumatic support mechanism 9 fixed on the base plate 1 is provided at the bottom of the radiator mounting hole 4, and a groove base 10 is connected to the upper part of the pneumatic support mechanism 9. A radiator 11 is placed above the groove base 10. A groove is provided at the bottom of the groove base 10, and the shape of the groove matches the cross-sectional shape of the radiator 11. The groove base 10 that matches the cross-sectional shape of the radiator is replaced accordingly to ensure welding quality;

[0027] The positioner 2, the horizontal clamping positioning device, and the upper clamping device are connected to the central controller. The central processor controls and adjusts the positioner 2, the horizontal clamping positioning device, and the upper clamping device. In an emergency, the drive stops working to ensure production safety.

[0028] The horizontal pressing and positioning device comprises a symmetrically arranged cylinder 5 and a positioning gripper 6. The piston of the cylinder 5 is connected to the positioning gripper 6. The movement of the cylinder 5 is controlled by a central controller.

[0029] The upper clamping device includes a cylinder column 7 and a clamping rod 8. The bottom of the cylinder column 7 is fixed on the base plate 1, and the top of the cylinder column 7 is connected to the clamping rod 8. The clamping rod 8 is located above the radiator 11.

[0030] The radiator used in this embodiment has protrusion structures evenly arranged around the shell, and the welding cross-section of the radiator is rectangular.

[0031] A method of using an aluminum alloy sealed radiator welding tool is as follows:

[0032] 1. Fix the pneumatic support mechanism 9, the upper clamping device, and the positioner 2 to the base plate 1, fix the groove base 10 to the pneumatic support mechanism 9, assemble the flip frame 3 and the positioner 2, and then fix the horizontal clamping and positioning device to the flip frame 3, assemble the radiator with the groove base 10 through the radiator mounting hole 4 in the middle of the flip frame 3, and clamp and position it through the horizontal clamping and positioning device, assemble the radiator upper sealing plate 1101 with the radiator 11, and clamp the upper clamping device on the upper sealing plate 1101;

[0033] 2. After assembly, welding is performed through the welding system. Welding is divided into positioning spot welding and welding. The positioning welding position is the 114 sharp corner positions of the radiator.

The positioner 2 controls the flip frame 3 to change the position. After the position change is completed, the pneumatic support mechanism 9 moves upward to make the groove base 10 contact the radiator 11, and the lower sealing plate 1102 is assembled with the radiator 11. The upper clamping device clamps the lower sealing plate 1102. After the assembly is completed, welding is carried out. The welding is divided into positioning spot welding and welding.

After the positioning spot welding is completed, the upper clamping device is opened to avoid interference during the welding process, and then welding is carried out. One week of welding seam, welding is completed in one time;

[0035] 4. After all welding is completed, the control and adjustment system stops welding according to the feedback information, and the central controller controls the removal of the upper clamping device, the horizontal clamping positioning device, and the pneumatic support device to take out the sealed radiator.
