[0002] The tube box is a component used to fix the two ends of multiple finned tubes in the air-cooled heat exchanger. According to different models of air-cooled heat exchangers, there are multiple rows of mounting holes with the same hole spacing on the panel of the tube box, and the mounting holes in two adjacent rows are staggered. Different models of air-cooled heat exchangers have different numbers of mounting holes in each row.

[0003] During assembly, the two ends of the fin tube need to be inserted into the corresponding holes respectively. In order to ensure the sealing between the tube box panel and the two ends of the fin tube, the connection between the tube box panel at the end of the fin tube is connected by welding.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0027] like Figure 1-Figure 6 As shown, this embodiment provides an air cooler tube box welding device, which is movably arranged at one end of the tube box fixing mechanism, and is used to weld and fix the connection between the tube box panel 1 and the fin tube after the tube box and the fin tube are assembled. It includes a mounting seat 10, an adjusting portion 20, and a plurality of welding portions 30. The adjusting portion 20 is penetrated on the mounting seat 10, and the welding portion 30 is arranged at the output end of the adjusting portion 20; the adjusting portion 20 is used to adjust the distance between two adjacent welding portions 30 so as to meet the welding of different hole spacings on the tube box panel 1.

[0028] Specifically, Figure 1-Figure 3 As shown, the two ends of the outer side of the mounting seat 10 extend outward and are respectively provided with fixed seats, a round rod 11 is provided between the two fixed seats, and a guide groove 12 is provided on the mounting seat 10. The length direction of the guide groove 12 corresponds to the length direction of the round rod 11, that is, the projection of the midline of the length direction of the round rod 11 on the mounting plate 10 overlaps with the midline of the guide groove 12.

[0029] A T-slot 13 is provided below the guide slot 12 . The vertical portion of the T-slot 13 is horizontally arranged and disposed in the mounting seat 10 . That is, the vertical portion of the T-slot 13 passes through the inner side surface of the mounting seat 10 , while the horizontal portion does not pass through the outer side surface of the mounting seat 10 .

[0030] The adjusting part 20 includes a plurality of movable seats 21, the rear end of the movable seat 21 passes through the guide groove 12 and is connected with an equal-distance mechanism. The equal-distance mechanism is realized by a cylinder in combination with a plurality of connecting plates. The plurality of connecting plates are hinged in sequence, the end of the connecting plate at one end is connected to the output end of the cylinder, and the middle part of the connecting plate at the other end is connected to one end of the round rod 11 through a rotating pin, and the top of the rear end of the movable seat 21 is rotatably connected to the middle part of the connecting plate in sequence, so that when the cylinder pushes the connecting plate to move along the round rod 11, the distance between the movable seats 21 is synchronously adjusted at equal intervals.

[0031] It is worth noting that when the cylinder pushes the connecting plate to expand to the maximum position, there is still a predetermined angle between the connecting plates, which prevents the connecting plates from expanding to form a straight path and causing jamming during the return stroke.

[0032] The front end of the movable seat 21 is connected to a seat plate 22, and a connecting seat 23 is provided at the lower end of the seat plate 22. The connecting seat 23 extends in the direction of the mounting plate 10, and the rear end of the connecting seat 23 is rolled in the T-slot 13 to prevent the seat plate 22 from rotating when the movable seat 21 moves, so as to improve the stability during welding. A rotating mechanism is provided in the seat plate 22, and the output end of the rotating mechanism extends through the seat plate 22 to a side away from the mounting seat 10.

[0033] The welding part 30 includes a turntable 31 . The number of the turntables 31 corresponds to the number of the movable seats 21 . One side of the turntable 31 facing the mounting plate 10 is connected to the output end of the rotating mechanism. The other side of the turntable 31 is provided with a welding gun 32 .

[0034] When in use, according to the distance between the apertures on the tube box panel 1, the equal distance mechanism is started to align the welding gun 32 with the welding position of each hole, and then the welding gun and the rotating mechanism are started in sequence to perform welding operations on the connection between the holes on the tube box panel 1 and the ends of the fin tubes.

[0035] Specifically, Figure 4 As shown, a truncated cone 211 is provided at the rear end of the movable seat 21, and a circular hole 212 is provided along the radial direction of the truncated cone 211. The circular hole 212 is slidably matched with the round rod 11 to reduce the friction between the movable seat 21 and the round rod 11. A roller 213 is sleeved at the rear end of the movable seat 21, and the roller 213 is rolling matched with the guide groove 12 to reduce the load of the equal distance mechanism when the welding gun 32 is adjusted equidistantly.

[0036] Specifically, Figure 4 As shown, a circular plate 231 is rotatably provided at one end of the connecting seat 23, and the circular plate 231 rolls with the horizontal portion of the T-slot 13, which can not only make the welding gun 32 have better stability during welding, but also further reduce the resistance of the equal distance mechanism when adjusting the distance of the welding gun 32.

[0037] Specifically, Figure 5-Figure 6 As shown, a movable groove 311 is opened along the radial direction of the turntable 31, a strip groove 312 is provided on one side of the movable groove 311, an adjustment seat 321 is provided at one end of the welding gun 32, and the adjustment seat 321 is movably arranged in the movable groove 311 so that the welding gun 32 can meet the welding of fin tubes with different diameters; a locking piece 313 is provided in the strip groove 312, and the locking piece 313 is used to tighten the adjusting seat 321. When the welding gun 32 is locked during operation, the locking piece 313 can be loosened to remove it when it needs to be replaced, so it is convenient to replace.

[0038] Specifically, Figure 6As shown, a scale line is provided on the other side of the movable groove 311 to improve the accuracy of adjusting the position of the welding gun 32 and reduce the welding position error.

[0039] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
