DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] See also Figure 1-3 A four-way welding device includes a chassis 1, a rotating column 2 rotatably connected to the chassis 1, a support base 3 connected to the rotating column 2, and a first drive mechanism disposed within the chassis 1 for driving the rotating column to rotate. Specifically, the first drive mechanism includes a first motor 16 mounted within the chassis, a transmission shaft connected to the first motor via a coupling, a main gear 17 connected to the transmission shaft, and a sub-gear 18 connected to the rotating column, wherein the main gear 17 and the sub-gear 18 mesh. When the first motor 16 is started, the main gear 17 and the sub-gear 18 cooperate to drive the rotating column 2 to rotate, thereby driving the support base 3 to rotate.

[0026] The chassis 1 is connected to a wall panel on one side of the rotating column, and the wall panel is connected to a top panel. The top panel is connected to a lifting plate 4 via a lifting mechanism. The bottom surface of the lifting plate 4 is rotatably connected to a pressure seat 5 via a rotary bearing. The pressure seat 5 is located directly above the support seat 3. The opposing surfaces of the support seat 3 and the pressure seat 5 are provided with mutually matching and cross-shaped positioning grooves. The lifting mechanism includes a third cylinder 19 installed on the top panel and a guide rod 20 slidably connected to the top panel. The telescopic end of the third cylinder 19 and the guide rod 20 are both connected to the lifting plate 4. The four-way valve is placed in the positioning groove, and then the third cylinder 19 is controlled to extend, driving the lifting plate 4 to descend, thereby driving the pressure seat 5 to descend, and pressing the four-way valve onto the support seat 3. At this time, the four-way valve is aligned with the chuck. Since the pressure seat 5 is rotatably connected to the lifting plate 4 via the rotary bearing, the rotation of the support seat 3 can drive the four-way valve on it to rotate together.

[0027] A first displacement mechanism is provided on one side of the chassis 1, and is connected to a first slide 6 via the first displacement mechanism. The first displacement mechanism includes two first bearing blocks 21 connected to the chassis, a first screw rod 22 rotatably connected to the two first bearing blocks, a guide rail 23 provided on the chassis, and a second motor 24 mounted at one end of the chassis and drivingly connected to the first screw rod. The first slide 6 is threadedly connected to the first screw rod 22, and the first slide 6 is slidably connected to the guide rail 23. When the second motor 24 is activated, the first screw rod 22 rotates, thereby driving the first slide 6 to move along the guide rail 23, causing the chuck 8 to move toward the support base 3.

[0028] The first slide 6 is rotatably connected to a rotating shaft 7, one end of which is connected to a vertical chuck 8 for clamping the flange. The chuck 8 is equipped with multiple clamping mechanisms, including several fourth cylinders 25 installed on the chuck's periphery and clamping plates 26 connected to the retractable ends of the fourth cylinders. The clamping plates 26 are located inside the chuck 8. When the flange is placed in the chuck, the fourth cylinders are controlled to extend, driving the clamping plates to press the flange tightly into the chuck, thereby maintaining the flange's stability.

[0029] The first slide 6 is provided with a second driving mechanism for driving the rotating shaft 7 to rotate, and the second driving mechanism is a fourth motor 31 installed on the first slide, and the fourth motor 31 is connected to the rotating shaft 7 through a coupling; one side of the chuck 8 is connected to an L-shaped support frame 9, and the support frame 9 is installed with a first cylinder 10, and the telescopic end of the first cylinder 10 is connected to a mounting plate 11, and the bottom surface of the mounting plate 11 is connected to the second slide 12 through a second displacement mechanism, and the second displacement mechanism includes two second bearing seats 27 connected to both ends of the connecting plate, a second screw rod 28 rotatably connected to the two second bearing seats, a guide rod 29 connected to the two second bearing seats, and a third motor 30 installed at one end of the connecting plate and transmission connected to the second screw rod, the second slide 12 is threadedly connected to the second screw rod 28, and the second slide 12 is slidably connected to the guide rod 29. The bottom surface of the second slide 12 is connected to a connecting plate 13. A welding gun 14, which bends toward the chuck 8, is hingedly connected to one side of the bottom surface of the connecting plate 13. A second air cylinder 15 is hingedly connected to the other side of the bottom surface of the connecting plate 13. The second air cylinder 15 is movably connected to the body of the welding gun 14. When the third motor 30 is activated, it rotates the second screw rod 28, thereby moving the second slide 12 along the guide rod 29, thereby moving the welding gun 14 toward the connection between the flange and the cross-piece for welding.

[0030] The working principle of this embodiment is:

[0031] The spool 32 is placed in the positioning groove of the support base 3. The third cylinder 19 is then controlled to extend, driving the lifting plate 4 to descend, thereby driving the pressure seat 5 to descend and press the spool onto the support base 3. At this time, the spool is aligned with the chuck 8. The flange 33 is then placed in the chuck 8. The fourth cylinder 25 is controlled to extend, driving the clamping plate 26 to press the flange 33 tightly into the chuck 8, thereby maintaining the flange stability. The second motor 24 is then started to drive the first screw 22 to rotate, thereby driving the first slide 6 to move along the guide rail 23, so that the chuck 8 moves toward the support base 3 until the flange contacts one end of the spool. The first cylinder 10 is then controlled to extend, driving the mounting plate 11 to move downward. The second cylinder 15 is then controlled to operate, driving the welding gun to rotate, so that the welding gun 14 faces the connection between the spool and the flange. The third motor 30 is then started to drive the second screw 28 to rotate, thereby driving the second slide 12 to move along the guide rod 29, so that the welding gun 14 moves toward the connection between the flange and the spool and contacts the connection between the flange and the spool. During welding, the connection between the four-way and the flange is welded by the welding gun. After welding a point, the clamping mechanism is separated from the flange, and then the fourth motor 31 is used to control the rotation of the rotating shaft 7, driving the chuck 8 to rotate, thereby driving the welding gun to rotate, so that the welding gun rotates around the periphery of the connection between the four-way and the flange, thereby performing all-round welding of the four-way and the flange. After the welding is completed, the chuck is driven to leave the four-way through the first displacement mechanism, and then the first drive mechanism is used to control the rotation of the rotating column, adjust the direction of the four-way, and weld the remaining end faces of the four-way.
