Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: A welding device for heat exchanger manufacturing includes a base 1 and a welding machine 2. A welding table 3 is fixedly installed on the top of the base 1. The welding machine 2 is mounted on the welding table 3. Symmetrical electric telescopic columns 4 are fixedly installed on both sides of the welding table 3. A slide rail 5 is provided on the welding table 3. A movable plate 6 is horizontally slidably arranged on the slide rail 5. Symmetrical vertical plates 7 are fixedly installed on the movable plate 6. Symmetrical electric push rods 8 are fixedly installed on the outer sides of the vertical plates 7. A clamping plate 9 is fixedly installed at the output shaft end of each electric push rod 8 on both sides. The clamping plate 9 is arc-shaped. The movable plate... The base 1 and its components are provided with two sets of electric telescopic columns 4. The output shaft ends of the two sets of electric telescopic columns 4 are fixedly installed on the sides of the two sets of movable plates 6 respectively. The base 1 is fixedly installed with symmetrical electric telescopic columns 10 on both sides. The output shaft ends of the electric telescopic columns 10 are fixedly installed with connecting columns 11. The ends of the connecting columns 11 are rotatably provided with discs 12. The discs 12 are fixedly installed with evenly distributed electric push rods 2. The discs 12 are slidably provided with blocks 13. The number of blocks 13 is the same as the number of electric push rods 2. The output shaft ends of the electric push rods 2 are fixedly installed with the blocks 13 respectively.

[0022] In use, the base 1 and the welding table 3 are used to support the entire device; When welding the two sets of tube shells, the two sets of tube shells are loaded into the two sets of symmetrical clamping plates 9 respectively. At the same time, the electric push rod 8 on the vertical plate 7 is activated. The output shaft of the electric push rod 8 extends and retracts to push the arc-shaped clamping plate 9, which is fixed at both ends, closer to the tube shell until the clamping plate 9 is in contact with the outer wall of the tube shell to achieve initial positioning. Next, the symmetrical electric telescopic columns 4 fixedly installed on both sides of the welding table 3 are activated. The output shaft of the electric telescopic column 4 pushes the movable plate 6, which is horizontally slidably set on the upper slide 5 of the welding table 3, to move, thereby driving the two sets of tube shells to move horizontally and approach each other, so that the ends of the two sets of tube shells are docked and positioned. After the two sets of tube shells are aligned and positioned, the two symmetrical electric telescopic columns 10 fixedly installed on both sides of the base 1 are activated. The output shaft of the electric telescopic column 10 extends and retracts, causing the connecting column 11 fixedly installed at the end to move closer to each other. The connecting column 11 moves closer to each other, causing the disc 12 fixedly installed at the end to be inserted into the openings at the ends of the two sets of tube shells respectively. Then, the evenly distributed electric push rods 2 fixedly installed inside the disc 12 are activated. The output shaft of the electric push rod 2 extends and retracts, pushing the sliding block 13 on the disc 12 to move towards the inner wall of the tube shell until the block 13 is in close contact with the inner wall of the tube shell, thus completing the full positioning of the tube shell. After positioning, start welding machine 2 to weld the joint of the two sets of pipe shells. After welding a part, loosen clamp 9. Since the disc 12 is rotated at the end of the connecting column 11, the operator can rotate the pipe shell to weld the two sets of pipe shells synchronously. The welding equipment used in the manufacture of this heat exchanger can perform positioning and rotation welding on two sets of tube shells, which effectively improves welding efficiency and is highly practical.

[0023] Both the clamping plate 9 and the abutment block 13 are covered with pads, which are made of rubber. Both the clamping plate 9 and the abutment block 13 are covered with rubber pads. When the clamping plate 9 is in contact with the outer wall of the tube shell and the abutment block 13 is in contact with the inner wall of the tube shell, the rubber pads can increase the friction with the tube shell and prevent the tube shell from sliding and shifting during clamping. At the same time, the rubber material has a certain elasticity, which can buffer the squeezing damage to the surface of the tube shell caused by the clamping force, thereby improving the stability of the tube shell during clamping and rotation.

[0024] Electric telescopic columns 14 are fixedly installed at the bottom of the movable plate 6, and a lifting plate 15 is slidably installed on the top of the movable plate 6. The output shaft end of the electric telescopic columns 14 is fixedly installed with the lifting plate 15. The electric telescopic column 14 at the bottom of the movable plate 6 is activated, and its output shaft pushes the lifting plate 15 to rise or fall. This can drive the tube shell to rise and fall vertically during loading, making it easier to clamp and fix the tube shell.

[0025] A magnetic plate is fixedly installed inside the lifting plate 15; When the tube shell is fed through the lifting plate 15, the magnetic plate fixedly installed inside the lifting plate 15 attracts the tube shell, which can improve the stability of the tube shell feeding and further facilitate the clamping and fixing of the tube shell.

[0026] A level is installed on the side of the base 1; A level is installed on the side of the base 1 to facilitate the stable placement of the entire device.

[0027] The welding table 3 is equipped with a controller, which is electrically connected to the welding machine 2, the electric telescopic column 4, the electric push rod 8, the electric telescopic column 10, the electric push rod 2, and the electric telescopic column 3 14 respectively. The welding table 3 is equipped with a controller, which is electrically connected to the welding machine 2, electric telescopic column 1 4, electric push rod 1 8, electric telescopic column 2 10, electric push rod 2, and electric telescopic column 3 14. Through the controller, the various components of the device can be automatically controlled, thereby improving the degree of automation in welding.

[0028] Working principle: In use, the base 1 and the welding table 3 are used to support the entire device; When welding the two sets of tube shells, the two sets of tube shells are loaded into the two sets of symmetrical clamping plates 9 respectively. At the same time, the electric push rod 8 on the vertical plate 7 is activated. The output shaft of the electric push rod 8 extends and retracts to push the arc-shaped clamping plate 9, which is fixed at both ends, closer to the tube shell until the clamping plate 9 is in contact with the outer wall of the tube shell to achieve initial positioning. Next, the symmetrical electric telescopic columns 4 fixedly installed on both sides of the welding table 3 are activated. The output shaft of the electric telescopic column 4 pushes the movable plate 6, which is horizontally slidably set on the upper slide 5 of the welding table 3, to move, thereby driving the two sets of tube shells to move horizontally and approach each other, so that the ends of the two sets of tube shells are docked and positioned. After the two sets of tube shells are aligned and positioned, the two symmetrical electric telescopic columns 10 fixedly installed on both sides of the base 1 are activated. The output shaft of the electric telescopic column 10 extends and retracts, causing the connecting column 11 fixedly installed at the end to move closer to each other. The connecting column 11 moves closer to each other, causing the disc 12 fixedly installed at the end to be inserted into the openings at the ends of the two sets of tube shells respectively. Then, the evenly distributed electric push rods 2 fixedly installed inside the disc 12 are activated. The output shaft of the electric push rod 2 extends and retracts, pushing the sliding block 13 on the disc 12 to move towards the inner wall of the tube shell until the block 13 is in close contact with the inner wall of the tube shell, thus completing the full positioning of the tube shell. After positioning, start welding machine 2 to weld the joint of the two sets of pipe shells. After welding a part, loosen clamp 9. Since the disc 12 is rotated at the end of the connecting column 11, the operator can rotate the pipe shell to weld the two sets of pipe shells synchronously. The welding equipment used in the manufacture of this heat exchanger can perform positioning and rotation welding on two sets of tube shells, which effectively improves welding efficiency and is highly practical. in, Both the clamping plate 9 and the abutment block 13 are covered with rubber pads. When the clamping plate 9 is in contact with the outer wall of the tube shell and the abutment block 13 is in contact with the inner wall of the tube shell, the rubber pads can increase the friction with the tube shell and prevent the tube shell from sliding and shifting during clamping. At the same time, the rubber material has a certain elasticity, which can buffer the squeezing damage to the surface of the tube shell caused by the clamping force, thereby improving the stability of the tube shell during clamping and rotation. The electric telescopic column 14 at the bottom of the movable plate 6 is activated, and its output shaft pushes the lifting plate 15 to rise or fall, which can drive the tube shell to rise and fall vertically during feeding, making it easy to clamp and fix the tube shell. When the tube shell is fed through the lifting plate 15, the magnetic plate fixedly installed inside the lifting plate 15 attracts the tube shell, which can improve the stability of the tube shell feeding and further facilitate the clamping and fixing of the tube shell. A level is installed on the side of the base 1 to facilitate the stable placement of the entire device; The welding table 3 is equipped with a controller, which is electrically connected to the welding machine 2, electric telescopic column 1 4, electric push rod 1 8, electric telescopic column 2 10, electric push rod 2, and electric telescopic column 3 14. Through the controller, the various components of the device can be automatically controlled, thereby improving the degree of automation in welding.
