[0061] Specifically, the welding head 10 can be aligned with the position to be welded by rotating the adjusting rod 28 and the welding head 10. Under the action of the first rotation damping 29 and the second rotation damping 31, the adjusting rod 28 and the welding head 10 can remain stationary at any position, thereby enabling the welding head 10 to weld at a specified position.

[0062] Through the above structures and steps, the cold box welding equipment can realize the positioning of the rotating table 9 and the angle adjustment of the welding head 10, and then perform stable welding operations at the specified position.

[0063] Reference Figure 7 The cold box welding equipment includes a moving plate 8, and two support arms 49 are fixedly connected to the side of the moving plate 8 away from the main column 2. The two support arms 49 are respectively located above and below the fixed column 23, and the end of the support arm 49 away from the main column 2 is in conflict with the rotating table 9, which is used to provide stable support for the rotating table 9. In order to further enhance the connection stability between the support arm 49 and the rotating table 9 and ensure that the rotating table 9 can rotate smoothly, a sliding block 48 is fixed to the end of the two support arms 49 away from the moving plate 8. At the same time, two arc grooves 47 are provided on the side of the rotating table 9 close to the moving plate 8. The two arc grooves 47 are slidably matched with the sliding block 48, so that the rotating table 9 is more stable when rotating.

[0064] Reference Figure 2 Furthermore, in order to realize the up and down movement of the movable plate 8, so as to adjust the position of the welding head 10 during the welding process, a motor is fixed to the top of the cover plate 6 of the equipment through a frame. The output shaft of the motor is fixedly connected to the top of the screw rod 7 through a coupling, so that the screw rod 7 can be driven to rotate when the motor is driven, and then the up and down movement of the movable plate 8 is realized through the threaded cooperation between the screw rod 7 and the movable plate 8. In order to ensure the stability of the cover plate 6 during the movement, a plurality of positioning grooves are provided on the top of the main column 2, and a plurality of positioning rods are fixed on the bottom of the cover plate 6. These positioning rods cooperate with the positioning grooves to limit the cover plate 6 so that it can remain stable when the motor drives the screw rod 7 to rotate.

[0065] Example 2

[0066] refer to Fig.11 and Fig.12 , improved on the basis of Example 1: Finally, in order to protect the user's eyes from the strong light stimulation generated during welding and to facilitate the user to observe the welding status, a rubber shaft 50 runs through the second shaft 30 of the device. Both ends of the rubber shaft 50 are fixed with first welding lenses 51, and two second welding lenses 52 are also fixed on the side where the two first welding lenses 51 are close to each other.

[0067] In this way, the two first welding lenses 51 are fixedly connected together by the two second welding lenses 52. When the welding head 10 is welding, the user can change the angles of the first welding lens 51 and the second welding lens 52 by adjusting the rubber shaft 50, so that they can effectively block the light generated during welding without hindering the user from observing the welding status.

[0068] A method for using a cold box welding device comprises the following steps:

[0069] S1. When in use, the card plate 18 is bent to one side to release the brake of the card plate 18 on the U-shaped card block 16, and the nut block 11 can be rotated. The height of the connecting ring 12 and the mounting plate 14 can be controlled by the cooperation of the nut block 11 and the screw rod 7. The magnetic attraction between the neodymium magnet 15 and the electromagnet 20 is used to control the placement height of the movable plate 8, so that the movable plate 8 can be placed in a suitable position to weld the gaps between the first mounting seat 3 and the main column 2, and the second mounting seat 4 and the main column 2. The card plate 18 is released, and the card plate 18 is clamped with the U-shaped card block 16 again under the action of the first spring 19. Then the screw rod 7 is inserted into the base 1, and the positioning rod at the bottom of the cover plate 6 is inserted into the positioning groove at the top of the main column 2 to position the cover plate 6;

[0070] S2, fit the movable plate 8 to the outer wall of the main column 2, at which time the main column 2 is located between the first mounting seat 3 and the second mounting seat 4, and energize the electromagnet 20. The cooperation between the electromagnet 20 and the neodymium magnet 15 can adsorb the movable plate 8 to the outer wall of the main column 2, and the rubber wheel 22 is close to the outer wall of the main column 2, and then rotate the adjusting rod 28 and the welding head 10 to align the welding head 10 with the position to be welded. Under the action of the first rotation damping 29 and the second rotation damping 31, the adjusting rod 28 and the welding head 10 can remain stationary at any position, and then the motor drives the lead screw 7 to rotate slowly, and the lead screw 7 drives the movable plate 8 to rotate through the nut block 11, the neodymium magnet 15 and the electromagnet 20, and the movable plate 8 drives the welding head 10 to slowly move on the outer wall of the main column 2 for welding; in addition, during welding, it is necessary to manually hold the first mounting seat 3 to position the first mounting seat 3, so as to facilitate the welding of the welding head 10 in the later stage;

[0071] S3. When the moving plate 8 moves, the rubber wheel 22 rotates, and the rubber wheel 22 drives the guide rod 38 to move intermittently outward through the arc-shaped protrusion 40. When the guide rod 38 moves outward, it pushes the trapezoidal block 37, the connecting block 33 and the sliding plate 25 to move up a certain distance with the cooperation of the inclined surface of the trapezoidal block 37. Therefore, the rotation of the rubber wheel 22 can control the welding head 10 to swing back and forth up and down during the welding process, thereby making the welding of the first mounting seat 3 and the top of the main column 2 more stable and avoiding the phenomenon of intermittent welds;

[0072] S4. When it is necessary to weld the second mounting seat 4 and the bottom of the main column 2, the connecting rod 45 and the circular plate 42 are pressed, and the pin 44 is disengaged from the pin hole 46. Then, the connecting rod 45 drives the rotating table 9 to rotate 180° until the welding head 10 is aligned with the welding position of the second mounting seat 4 and the main column 2. Then, the pressing of the connecting rod 45 is released, and the pin 44 is re-engaged in the pin hole 46 under the action of the third spring 43, so that the positioning of the rotating table 9 is completed, so as to facilitate the stable welding of the second mounting seat 4 and the bottom of the main column 2 in the later stage.

[0073] S5. In addition, when the welding head 10 is welding, the angles of the first welding lens 51 and the second welding lens 52 can be adjusted through the rubber shaft 50, so that the first welding lens 51 and the second welding lens 52 can block the light during welding, allowing the user to observe the welding status.

[0074] However, as is well known to those skilled in the art, the working principle and wiring method of the electromagnet 20 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selection according to their needs or convenience.

[0075] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
