The lifting and translating component moves the semi-circular slide rail and the vibrator to the side of the semi-circular head of the square tube to be welded. At this point, the vibrating strip is in contact with the outer surface of the semi-circular head at the folded position. Then, the vibrator drives the vibrating strip to vibrate, causing the vibrating strip to repeatedly vibrate the arc-shaped metal plate at the folded position. During the tapping process, the vibrator makes a semi-circular movement on the semi-circular slide rail, so that the entire folded position is vibrated and tapped, ensuring that the metal at the folded position is fully bent and deformed under the action of the tapping vibration, so that the inner side of the folded position is completely in contact, avoiding the appearance of a weld seam. Then, the vibrator is controlled to move away, and the drive mechanism is controlled to move the welding gun to the weld position for moving welding. After welding one side, the square tube to be welded is flipped over, and the weld seam on the other side is welded. Attached Figure Description

[0082] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0083] In existing technologies, there are various welding methods for steel pipes, one of which is folding welding, which involves folding a square tube in half to obtain a folded steel pipe with a semi-circular head, such as... Figure 15 As shown, the square tube 4 to be welded is initially in an unfolded state. A double-arc notch is cut out in the middle of the square tube 4 to be welded, so that the two sides of the steel tube can be folded towards the middle for welding.

[0084] Example 1

[0085] like Figure 1-6 As shown, this embodiment proposes an automated welding device, including a machine tool plate 1, on which two first slide rails 2 are installed, and welding tables 3 are slidably arranged on the two first slide rails 2, and the square tube 4 to be welded is placed on the welding tables 3.

[0086] Also includes:

[0087] A drive mechanism, which is mounted on the machine tool plate 1;

[0088] Welding torch 11, which is mounted on the drive end of the drive mechanism and can be adjusted in multiple directions;

[0089] The vibration bonding mechanism includes a lifting and translating assembly, a semi-circular slide rail 14, and a vibrator 15. The lifting and translating assembly is mounted on the machine tool plate 1. The semi-circular slide rail 14 is mounted on the moving end of the lifting and translating assembly. The vibrator 15 is electrically and slidably mounted in the semi-circular slide rail 14. The vibrator 15 is provided with a tapping strip 16.

[0090] In this embodiment, after the square tube is folded in half, the square tube 4 to be welded is fixed on the welding table 3. Then, the welding table 3 moves the square tube 4 to be welded on the first slide rail 2 until it is below the welding torch 11. At this time, one end of the folded square tube 4 to be welded is fixed, leaving one end of the semi-circular head exposed. The lifting and translation component moves the semi-circular slide rail 14 and the vibrator 15 to the side of the semi-circular head of the square tube 4 to be welded. At this time, the vibrating strip 16 is attached to the outer surface of the semi-circular head at the folded position. Then, the vibrator 15 drives the vibrating strip 16 to vibrate, causing the vibrating strip 16 to vibrate. The curved metal plate at the fold position is repeatedly vibrated during the tapping process. The vibrator 15 moves in a semi-circular motion on the semi-circular slide rail 14, so that the entire fold position is vibrated and tapped. This ensures that the metal at the fold position is fully bent and deformed under the action of the tapping vibration, so that the inner side of the fold position is completely attached, avoiding the appearance of weld seams. Then, the vibrator 15 is controlled to move away, and the drive mechanism is controlled to move the welding gun 11 to the weld position for moving welding. After welding one side, the square tube 4 to be welded is flipped over, and the weld seam on the other side is welded.

[0091] Example 2

[0092] like Figure 1-6 As shown, based on Embodiment 1, the lifting and translation component includes:

[0096] The first lifting drive component 5, there are two first lifting drive components 5, and the two first lifting drive components 5 are symmetrically installed on the machine tool plate 1;

[0097] First mounting plate 6, there are two first mounting plates 6, and the two first mounting plates 6 are respectively mounted on the lifting ends of the two first lifting drive components 5;

[0098] The second slide rail 7 is provided in two, with each second slide rail 7 installed between two first mounting plates 6, and the two second slide rails 7 are symmetrically arranged.

[0099] A first electric slide 8 is slidably disposed on each of the second slide rails 7;

[0100] The third slide rail 9 is installed between the two first electric slide tables 8;

[0101] The second electric slide 10 is slidably mounted on the third slide rail 9;

[0102] Welding torch 11, which is mounted on the second electric slide table 10.

[0103] In this embodiment, the second lifting drive 12 and the first telescopic drive 13 can respectively drive the semi-circular slide rail 14, the vibrator 15 and the tapping strip 16 to lift, move and translate, so that the tapping strip 16 can move to a suitable position.

[0104] The second electric slide 10 can move horizontally on the third slide rail 9 to drive the welding torch 11 to move in the first direction. The third slide rail 9 can then drive the welding torch 11 to move in the second slide rail 7 in another direction via the first electric slide 8. The first lifting drive 5 can drive the welding torch 11 to move in the up and down direction.

[0105] Example 3

[0106] like Figure 1-6 As shown, based on Embodiment 2, a welding and fixing mechanism is also included, which includes:

[0107] The third lifting drive component 17 is mounted on the machine tool plate 1;

[0108] The second telescopic drive component 18 is installed on the lifting end of the third lifting drive component 17.

[0109] The first positioning clip 19 is a rectangular clip and is installed on the telescopic end of the second telescopic drive member 18.

[0110] A flip control assembly is mounted on the machine tool plate 1;

[0111] The second positioning clip 27 is mounted on the flip control assembly. The second positioning clip 27 is a semi-circular ring clip, and the opening of the second positioning clip 27 is opposite to the opening of the first positioning clip 19.

[0112] The flip control component includes:

[0113] The fourth lifting drive component 20 is mounted on the machine tool plate 1;

[0114] The second mounting plate 21 is mounted on the lifting end of the fourth lifting drive component 20;

[0115] Electric rotating shaft seat 22, which is mounted on the second mounting plate 21;

[0116] The third mounting plate 23 is mounted on the shaft of the electric rotating shaft seat 22;

[0117] The third telescopic drive component 24 is provided in two, and the two third telescopic drive components 24 are symmetrically installed on the third mounting plate 23.

[0118] A flip clamp 25, which is a rectangular clamp, is installed on the telescopic ends of the two third telescopic drive members 24, and a round hole is opened in the middle of the flip clamp 25.

The second positioning clamp 27 is installed on the telescopic end of the fourth telescopic drive member 26.

[0120] In this embodiment, when the welding table 3 moves the folded square tube 4 to the welding position and adjusts it using the vibrating bar 16, it needs to be fixed before welding. At this time, the third lifting drive 17 drives the second telescopic drive 18 and the first positioning clamp 19 to rise to a suitable position. Then, the second telescopic drive 18 extends and drives the first positioning clamp 19 to move to the folded end of the square tube 4 to be welded, clamping both sides horizontally to prevent the two folded square tube ends from shifting to both sides during welding, which would affect the welding. On the other side, the folded and bent end is then lifted. Then, the fourth lifting drive 20 drives the second positioning clamp 27 to rise upwards, and then the... The four telescopic drive components 26 drive the second positioning clamp 27 to move, fixing the folded end of the square tube. Then the welding gun 11 descends to perform welding. After the upper side is welded, the two third telescopic drive components 24 extend, driving the flipping clamp 25 to move to the upper and lower sides of the folded end to fix it. The first positioning clamp 19 on the other end is temporarily loosened. The fourth lifting drive component 20 raises it a certain distance. Then the electric rotating shaft seat 22 drives the flipping clamp 25 and the second positioning clamp 27 to rotate, causing the square tube to flip over. Then it is lowered and fixed again to weld the other side. This achieves automatic flipping and automatic fixing, ensuring the smooth progress of welding.

[0149] In this embodiment, the square tube 4 to be welded needs to be folded before welding. First, the square tube 4 is placed in the two fixed shells 30.

Then, the two transmission guide wheels 50 contact the two transmission rods 49, thereby driving the transmission rods 49 to move. The transmission rods 49 drive the first rack 46 and the second rack 48 to move towards the middle and compress the elastic element 47. Due to the misalignment of the teeth of the first rack 46 and the second rack 48, the first rack 46 will first drive the first spur gear 40 to rotate in the opposite direction, thereby driving the first... The mounting base 41, connecting rod 42, telescopic vibrating rod 43, and tapping rod 44 rotate synchronously in opposite directions. This allows the tapping rod 44 to adjust its angle during telescopic tapping, striking other positions at the folded location as well, and tapping outwards to ensure the uniformity and stability of the fold, thus reducing weld seams from the source. Similarly, when the first rack 46 stops meshing with the spur gear 40, due to the elasticity of the torsion spring shaft seat 39, the tapping rod 44 will move back to the midpoint of the fold. Then, the second rack 48 will drive the second spur gear 40 to rotate forward, and so on, the tapping rod 44 will... The metal at the folded position is tapped evenly, and the degree of bending is uniform and stable. When the fold reaches a certain degree, the fifth lifting drive component 37 is raised, causing the tapping rod 44 to move away. Then the square tube 4 to be welded continues to be folded. When the folding reaches the final stage, the two sixth telescopic drive components 34 extend again, driving the two push rods 35 to move closer to each other and abut against the two linkage columns 32 to ensure the stability of the folding force, so that the square tube 4 to be welded completes the final fold. Then, maintaining this state, the welding table 3 moves the folded square tube 4 to the tapping bar 16 for the next step of tapping the outside of the folded position.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
