The method is mainly widely applied to steel structure engineering built in a factory building. The gas shielded welding of the intelligent welding robot depends on CO₂The (carbon dioxide) gas protects the weld pool to obtain an acceptable weld, and therefore a steady flow of shielding gas must be ensured during the welding process. In the outdoor welding of the ship body, the protective airflow layer is disturbed by larger airflow, so that the laminar flow layer required by normal welding is changed into a turbulent flow layer, the arc striking performance of a welding gun is deteriorated, electric arc is unstable, splashing is increased, the forming quality of a welding seam is deteriorated, the protective effect is reduced, even, the protective airflow layer can be directly damaged by large wind power, air enters a molten pool, the defects of oxidation, air holes and the like of the welding seam are caused, and the application of the welding robot in outdoor construction is seriously influenced. Therefore, how to ensure the stability of the shielding gas flow when the welding robot performs outdoor welding becomes a key problem to be solved whether to perform construction in the field.

Detailed Description

The invention will be further explained with reference to the drawings.

Referring to fig. 1 to 2, the welding gun protection integrated device for an outdoor construction welding robot according to the present invention includes an external robot body 1 including: the welding gun comprises a welding gun 2, a welding gun clamping piece 3, a hollow rectangular frame 4, an inclined support piece 5 and a wind shield 6.

The welding gun clamping piece 3 is detachably connected to the robot body 1 and used for clamping the welding gun 2. Specifically, the torch holder 3 includes: a mounting seat 31, a connecting piece 32, a locking piece (not shown) and a clamping block 33.

The mounting seat 31 is fixed on the robot body 1 and is provided with a mounting groove. The connecting piece 32 is inserted into the mounting groove of the mounting seat 31. The locking member is provided in the mounting groove for locking or unlocking the connecting member 32. The clamping block 33 is fixedly connected with the connecting piece 32 and is provided with a pair of clamping openings 34 with adjustable opening, and the two clamping openings 34 are vertically distributed. The opening of the clamping opening 34 is adjusted to clamp the welding guns 2 with different specifications.

The hollow rectangular frame 4 is adapted to receive the tip portion of the welding torch 2. The diagonal bracing piece 5 is welded and connected with the hollow rectangular frame 4 and the robot body 1. A height adjusting part for adjusting the height may be provided at the robot body 1, and the diagonal stay 5 is welded to the height adjusting part. Thus, the hollow rectangular frame 4 can be integrally adjusted in height along with the height adjusting part in the robot welding process.

The windshield cover 6 is detachably arranged on the peripheral side face of the hollow rectangular frame 4, so that the windshield cover 6 can be conveniently replaced under the condition of damage, and the cost is saved. The wind shield 6 and the hollow rectangular frame 4 form a wind shield part, the gun head part of the welding gun 2 is positioned on the inner side of the wind shield part, outdoor strong wind weather can be resisted, an airflow layer around a welding object is stable, outside air is reduced to enter a molten pool protected by carbon dioxide or other protective gases, oxidation and air holes of a welding line are avoided, and welding quality in strong wind weather can be improved. Generally, the hollow rectangular frame 4 has a length of 200m, a width of 10mm and a height of 50 mm. The diagonal stay 5 is 150mm long.

A smoke outlet is formed in one side, opposite to the wind direction, of the wind shield 6; the smoke dust generated in the welding process can be effectively discharged, and the phenomenon that the welding quality is influenced because metal particles in the smoke dust enter protective gas to cause instability of an electric arc and a gas flow layer is avoided.

The wind shield 6 is made of fireproof flame-retardant material. The flame-proof type gas shielded arc welding device has the characteristics of non-combustibility, high temperature resistance, no toxic gas emission, good insulativity, good heat insulation, no melting or dropping, high strength and no shrinkage phenomenon, can not deform or burst under the action of flame at 1000 ℃, is fireproof for more than one hour, plays a role in protection under the environments of humidity, steam, smog and chemical gas, prevents sparks generated in gas shielded welding from igniting the wind shield, and avoids the phenomenon that the wind shield attracts electric arcs during welding to cause unstable electric arcs and influence the welding quality.

The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and therefore all equivalent technical solutions should also fall within the scope of the present invention, and should be defined by the claims.
