Description

Technical Field

[0001] This utility model relates to the field of straight seam welding, and in particular to a welding structure. Background Technology

[0002] Welding a two-layer, three-pass weld seam typically requires three welding torches, such as... Figure 1 First, weld the bottom layer a, then weld the top layer weld b, and finally weld the top layer weld c. During the welding process, the welder uses different welding techniques to achieve different requirements for the cross-section of each weld.

[0003] Mechanical welding of single-pass welds has great advantages, but it is difficult to meet the requirements of weld cross-sectional shape for different weld passes. Although there are now double-wire welding equipment, they can only meet the welding requirements of fillet welds in ship-shaped positions and cannot achieve fillet welds in horizontal positions. Utility Model Content

[0004] This utility model provides a welding structure, the purpose of which is to provide a welding structure to realize fillet welding at the horizontal welding position.

[0005] To achieve the above objectives, embodiments of this utility model provide a welding structure, comprising:

[0006] Connector;

[0007] A first connecting component and a second connecting component are provided. The first connecting component is disposed at the far end of the connecting seat, and the second connecting component is disposed at the near end of the connecting seat. The first connecting component drives the connecting seat to move in the z-axis direction, the x-axis direction, and rotate around the y-axis direction. A second welding torch is provided on the second connecting component. The second welding torch can move in the z-axis direction, the x-axis direction, and rotate around the y-axis direction under the drive of the second connecting component.

[0008] The third welding torch is located at the near end of the connector, and the angle between the third welding torch and the xy plane is 30° and the angle between the third welding torch and the xz plane is 85°. The front end of the second welding torch is biased towards the far end of the connector.

[0009] Preferably, the second welding torch has an angle of 55° with the xy plane and an angle of 95° with the xz plane, and the front end of the second welding torch is biased toward the near end of the connecting seat. The front ends of the second welding torch and the third welding torch are spaced 60mm apart in the y-axis direction.

[0010] Preferably, the first connecting component and the second connecting component have the same structure. The first connecting component is a cross slider, which includes a sliding sleeve and a sliding body disposed within the sliding sleeve. The sliding sleeve is provided with a first adjusting bolt and a second adjusting bolt facing each other in the x-axis direction and the z-axis direction, respectively. The first adjusting bolt passes through the sliding sleeve and is screwed to the sliding body, and the second adjusting bolt passes through the sliding sleeve and is screwed to the sliding body. The portion of the sliding body extending out of the sliding sleeve is also provided with a rotating part. The connecting seat is fixedly connected to the rotating part of the first connecting component, the sliding sleeve of the second connecting component is fixedly connected to the connecting seat, and the rotating part of the second connecting component is fixedly connected to the second welding torch.

[0011] Preferably, the welding structure further includes a second welding gun clip and a third welding gun clip, wherein the second welding gun is fixed on the rotating part of the second connecting assembly by the second welding gun clip, and the third welding gun is fixed on the connecting seat by the third welding gun clip.

[0013] Preferably, the connecting seat is a long strip-shaped angle steel connecting seat.

[0014] The above-described solution of this utility model has the following beneficial effects:

[0015] In this application, the second welding torch and the third welding torch are mounted on the connecting seat. The second welding torch can be adjusted independently on the connecting seat. When the position of the second welding torch is fixed, the relative position between the second welding torch and the third welding torch remains unchanged as the connecting seat moves. When welding weld b and weld c, the two welding torches simultaneously complete the welding of the second and third welds (b and c) of the cover layer, which can reduce the welding time of the cover layer weld by half, and the welding current of weld c can be reduced by 10%.

[0024] like Figure 2 and 3 As shown, an embodiment of this utility model provides a welding structure, including a connecting seat 1, a first connecting component 2, and a second connecting component 3. The first connecting component 2 is disposed at the distal end of the connecting seat 1, and the second connecting component 3 is disposed at the proximal end of the connecting seat 1. The first connecting component 2 is used to fix the connecting seat 1 on a welding traveling device so as to drive the connecting seat 1, the first connecting component 2, and the second connecting component 3 to move synchronously.

[0025] The aforementioned first connecting component 2 can drive the connecting seat 1 to move in the x-axis and z-axis directions and rotate in the y-axis direction. A second welding torch 4 is provided on the second connecting component 3. The second welding torch 4 can move around the z-axis and x-axis directions and rotate in the y-axis direction under the drive of the second connecting component 3. A third welding torch 5 is also provided at the near end of the connecting seat 1. The third welding torch 5 makes an angle of 30° with the xy plane and an angle of 85° with the xz plane. The front end of the second welding torch 4 is biased towards the far end of the connecting seat 1.

[0026] Furthermore, the aforementioned second welding torch 4 has an angle of 55° with the xy plane and an angle of 95° with the xz plane, and the front end of the second welding torch 4 is biased towards the near end of the connecting seat 1. The front ends of the second welding torch 4 and the third welding torch 5 are 60mm apart in the y-axis direction.

[0027] The aforementioned first connecting component 2 and second connecting component 3 are identical and can utilize existing parts that meet the functions, or they can adopt the structure provided in this application. Taking the first connecting component 2 as an example, the first connecting component 2 is a cross slider, which includes a sliding sleeve and a sliding body disposed within the sliding sleeve, with the sliding body extending out of the sliding sleeve. Waist-shaped grooves are provided on the surfaces of the sliding sleeve in the x-axis and z-axis directions. A first adjusting bolt and a second adjusting bolt are respectively disposed in the two waist-shaped grooves. The first adjusting bolt and the second adjusting bolt pass through the waist-shaped grooves and are screwed to the sliding body. When the first bolt and / or the second bolt are adjusted, the position of the sliding body in the x-axis and z-axis directions can be adjusted, realizing movement in the z-axis and x-axis directions. The portion of the sliding body extending out of the sliding sleeve is also provided with a rotating part. The connecting seat 1 is fixedly connected to the rotating part of the first connecting component 2, the sliding sleeve of the second connecting component 3 is fixedly connected to the connecting seat 1, and the rotating part of the second connecting component 3 is fixedly connected to the second welding torch 4.

[0028] Furthermore, the welding structure also includes a second gun clip 6 and a third gun clip 7. The second welding gun 4 is fixed to the rotating part of the second connecting assembly 3 by the second gun clip 6, and the third welding gun 5 is fixed to the connecting seat 1 by the third gun clip 7.

[0029] The aforementioned second gun clip 6 and third gun clip 7 have the same structure, including a C-shaped clip body, in which a slot is formed for clamping the second welding gun 4 and the third welding gun 5, and a locking bolt is provided at the opening of the clip body for clamping the second welding gun 4 or the third welding gun 5.

[0030] Preferably, the connecting seat 1 is a long strip-shaped angle steel connecting seat 1.

[0031] This application applies to the welding of two-layer, three-pass 10mm weld bead seams, including a horizontal plate 01 and an upper plate 02 perpendicular to the horizontal plate 01. The welding steps can be referred to as follows:

[0032] S1. Hoist the workpiece into the welding jig, move the welding travel device to position the workpiece at the weld initiation position, adjust the second connecting component 3 to align the welding wire of the second welding torch 4 with the weld, start the welding travel device and the second welding torch 4 to begin welding the weld, forming the bottom layer a. When the weld end is reached, turn off the second welding torch 4 and the welding travel device. In step S1, if the alignment of the second welding torch 4 deviates, the second connecting component 3 can be adjusted.

[0033] S2. Move the welding travel device to the starting position again, adjust the first connecting component 2 so that the welding wire of the third welding gun 5 is aligned with the fusion line of the bottom layer a and the upper plate 02, adjust the second connecting component 3 so that the welding wire of the second welding gun 4 is aligned with the fusion line of the bottom layer a and the horizontal plate 01, and the two welding guns are aligned. Start the welding travel device and the arc start switch of the second welding gun 4 to weld weld b; when the third welding gun 5 moves to the weld start position, start the arc start switch of the third welding gun 5 to weld weld c, and weld the cover weld with both guns at the same time.

[0034] In this application, since the interval between the third welding gun 5 and the second welding gun 4 is 60mm, the welding time of the cover layer can be reduced by half, and the welding current of the third weld can be reduced by 10%. The welding is changed from manual operation to mechanized welding, which reduces the labor intensity of welders, saves time and energy consumption, and ensures product quality.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
