Description

Technical Field

[0001] The utility model belongs to the technical field of workpiece welding devices, in particular to a submerged arc welding automatic welding tool. Background Art

[0002] The I-beam to be welded is one of the most commonly used steel sections in engineering. Conventional large I-beams in the prior art are usually welded by upper and lower flange plates and web plates. The flange plates are generally cantilever structures, and the web plates are generally located between the bottom plate and the panel. The fillet welds between the flange plates and the web plates are welded in multiple layers and multiple passes. The traditional welding process requires the use of submerged arc welding for base welding, and the flux has a great influence on the weld quality, resulting in a large workload for the welder. However, the traditional butt welding method mainly relies on welders, which not only has a large workload but also high costs. At the same time, subjective factors have a great influence, so the weld quality is uneven, and manual welding leads to uneven flux coating, which affects the quality of the weld. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide an automatic submerged arc welding tool, which can be more stable than manual welding, has good weld formation and high weld quality, and can reduce the workload of welders.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is as follows: a submerged arc welding automatic welding tool, comprising:

[0005] A base, the base comprising at least two cross-beam steels and connecting steels connecting the cross-beam steels;

[0006] Support steel, the support steel is at least two groups, and the support steel includes support angle steel and support section steel;

[0007] At least two sets of limiting steel sections, wherein the limiting steel sections are vertically fixed to the supporting steel sections;

[0008] and an automatic welding structure, the automatic welding structure comprising a track, a track limiting steel plate, a track supporting frame and a welding trolley, the welding trolley being provided with a welding gun;

[0009] The limiting steel and the supporting steel are fixed to the flange plate of the beam steel, the supporting angle steel is fixed to the beam steel, and the track is fixed to the supporting angle steel. The track limiting steel plate is fixed to both sides of the track, and the track supporting frame is fixed to both ends of the track. The I-beam to be welded is placed between the supporting steel and the limiting steel; the welding trolley is placed on the track, and one side flange plate of the I-beam to be welded is attached to the surface of the limiting steel. The supporting steel includes a first supporting steel and a second supporting steel, one end of the first supporting steel overlaps one end of the second supporting steel, and the angle between the first supporting steel and the second supporting steel is less than or equal to 90°.

[0010] Compared with the prior art, the beneficial effects of the utility model are: the first supporting steel in the limiting steel is perpendicular to the supporting steel, so that when the I-beam to be welded is placed between the first supporting steel and the limiting steel, the flange plate of the I-beam to be welded can fit with the end face of the limiting steel to prevent slippage; at the same time, the fillet weld between the web and the flange of the I-beam to be welded can be located directly below the welding gun. During welding, the flux in the welding gun can be evenly coated on the fillet weld, which can significantly improve the quality of the weld. The welding trolley can realize automatic welding by reciprocating along the track. The welding process is more stable than manual welding, the weld is well formed, and the workload of the welder can be reduced. At the same time, the angle between the first supporting steel and the second supporting steel is less than 90°, so that the supporting steel formed after the first supporting steel and the second supporting steel are overlapped can provide a more effective supporting angle for the I-beam to be welded, and its welding part can be more accurately located at the position where the welding gun is located.

[0011] In the above-mentioned welding tool, the height of the first supporting steel section is equal to the height of the second supporting steel section.

[0014] In the above-mentioned welding tool, the supporting angle steel is connected to the limiting steel, the track is placed on the supporting angle steel, and the welding trolley can reciprocate along the track.

[0015] In the above-mentioned welding tool, the automatic welding structures are at least two groups.

[0017] In the above-mentioned welding tool, the two groups of supporting steel sections have the same height.

[0018] In the above-mentioned welding tool, the height of the limiting steel is less than or equal to the height of the supporting steel.

The track support frame 430 is fixed on both sides of the track 410, and is fixed at both ends of the track 410. The I-beam 500 to be welded is placed between the support steel 200 and the limiting steel 300. The flange plate of the I-beam 500 to be welded is fixed by the limiting steel 300 to prevent slipping, so that the fillet weld between the web and the flange plate of the I-beam 500 to be welded is located directly below the welding gun 441. During welding, the flux in the welding gun 441 can be evenly coated on the fillet weld, and the welding trolley 440 reciprocates along the track 410 to realize automatic welding of the welding trolley 440 along the track 410. The welding process is more stable than manual welding, the weld is well formed, the weld quality is high, and the workload of the welder can be reduced. Of course, the present welding device does not limit the fixing method of the support steel 200 and the base 100. Preferably, the support steel 200 is fixed to the base 100 by welding.

[0024] Furthermore, the support steel 210 includes a first support steel 211 and a second support steel 212, one end of the first support steel 211 overlaps one end of the second support steel 212, the angle between the first support steel 211 and the second support steel 212 is less than 90°, or the angle between the first support steel 211 and the second support steel 212 is equal to 90°, and the first support steel 211 and the second support steel 212 are welded to the upper flange plate of the beam steel 110 of the base 100 after being paired, for placing the I-beam 500 to be welded. So that the support steel 210 formed by overlapping the first support steel 211 and the second support steel 212 can provide a more effective support angle for the I-beam 500 to be welded, so that when the I-beam 500 to be welded is placed on the support steel 210 and the limiting steel 300, its welding position can be more accurately located at the position of the welding gun 441, so that the welding gun 441 can weld the I-beam 500 to be welded more effectively during the automatic welding process, making the weld smoother and more beautiful. Of course, the welding tool does not limit the specific number of support steels 200. Preferably, the support steel 200 is divided into two groups, the heights of the two groups of support steels 200 are the same, and the positions of the two groups of support steels 200 are aligned up and down, so that when the I-beam 500 to be welded is placed on the support steel 200, both sides remain stable, which is conducive to the automatic welding process.

[0025] Furthermore, the height of the first support steel 211 is equal to the height of the second support steel 212, so the two groups of support steel 200 formed by the overlap of the first support steel 211 and the second support steel 212 can form a fixed equilateral triangle structure with the beam steel 110, so that the I-beam 500 to be welded can be placed on both sides of the welding tool, and multiple groups of welding work can be carried out simultaneously. Furthermore, the two ends of the connecting steel 120 are fixed to the web of the beam steel 110 to ensure that the base is more stable. Of course, the welding tool does not limit the specific position of the connecting steel 120. Preferably, the connecting steel 120 is located in the middle of the web of the beam steel 110, so that the two ends of the welding tool are more balanced and more stable during welding.

[0026] Furthermore, the welding carriage 440 is placed on the track 410, and a welding gun 441 is provided on the welding carriage 440. A side flange plate of the I-beam 500 to be welded is attached to the surface of the limiting steel 300. Preferably, the height of the limiting steel 300 is less than the height of the supporting steel 200, or the height of the limiting steel 300 is equal to the height of the supporting steel 200, so that the welding carriage 440 has sufficient welding space to prevent the limiting steel 300 from being too high and blocking the welding gun 441 from extending into the weld of the I-beam 500 to be welded. Preferably, the height of the limiting steel 300 is less than the height of the supporting steel 200. Of course, the present application does not limit the limiting steel 300 and the supporting steel 2 00 The definition range of the height is preferably, the vertical distance from one end of the beam steel 110 to the beam steel 110 is the measured value of the height; further, the limit steel 300 is vertically fixed to the support steel 200 structure; the fillet weld between the web and the flange plate of the I-beam 500 to be welded is located directly below the welding gun 441. During welding, the flux in the welding trolley 440 can be evenly coated on the fillet weld, so that the welding trolley 440 can be automatically welded along the track 410. Of course, this welding tool does not limit the fixing method of the limit steel 300 and the support steel 200. Preferably, the limit steel 300 and the support steel 200 are fixed by a vertical fixed welding method.

[0027] Furthermore, the support angle steel 212 is connected to the limiting steel 300, and the track 410 is placed on the support angle steel 212. The welding carriage 440 can reciprocate along the track 410, so that the welding tool can automatically weld the I-beam 500 to be welded. Of course, the device does not limit the length and structure of the support angle steel 212. Preferably, the length of the support angle steel 212 is greater than or equal to the width of the track 410, so that the support angle steel 212 can leave enough installation dimensions to fix the support track 410. The support angle steel 2 12 is fixed on both sides of the crossbeam steel 110.

The track limit steel plate 420 is fixed on both sides of the track 410 to prevent the welding trolley 440 from leaving the track 410. Of course, the present welding tool does not limit the specific fixing method of the track limit steel plate 420 and the track 410. Preferably, the track limit steel plate 420 is welded and fixed to the track 410. The track support frame 430 is fixed to both ends of the track 410 to support the track 410 so that the welding trolley 440 can move smoothly on the track 410. Of course, the present welding tool does not limit the fixing method of the track support frame 430 and the track 410. Preferably, the track support frame 430 is fixed to the track 410 by welding.
