Automatic stud welding device applicable to T-shape welding studs

Abstract

The invention discloses an automatic stud welding device applicable to T-shape welding studs. The automatic stud welding device comprises a three-axis movement platform, a plurality of automatic welding guns and a plurality of automatic feeding mechanisms, wherein the three-axis movement platform comprises a crossbeam, support legs, ground rails, horizontal movement sliding blocks and a three-axis movement driving mechanism, and lifting movement mechanisms are fixed on the horizontal movement sliding blocks; the automatic welding guns comprise welding shells, main shaft bodies, main shaft body driving mechanisms, welding stud chucks and ceramic ring clamps, and the welding gun shells are fixedly connected with the lifting movement mechanisms; the automatic feeding mechanisms comprise feed collets and mounting brackets, the feed collets are obliquely mounted on the mounting brackets and can move left and right or front and back, and the mounting brackets are fixedly connected with the horizontal movement sliding blocks at the corresponding positions. According to the automatic stud welding device, the automatic conveying of the T-shape welding studs sleeved by ceramic rings and the automatic clamping and separating of the T-shape welding studs and the protecting ceramic rings are realized; by combining the automatic stud welding device with the three-axis movement platform, the automatic stud welding of the T-shape welding studs can be realized.

Description

technical field [0001] The invention relates to a stud welding device, in particular to a device suitable for automatic stud welding of T-shaped welding studs, belonging to the technical field of stud welding equipment. Background technique [0002] T-shaped welding studs (also known as cylindrical head welding studs) are widely used as shear connectors (also known as shear keys) in steel structures and "steel-concrete" structures in construction and bridge construction. The stud welding method is planted and welded on steel beams, steel columns and other structures. A project (a high-rise building or a bridge) requires tens of thousands or even hundreds of thousands of T-shaped welding studs. According to statistics, the annual welding volume of T-shaped welding studs in Japan is 60 million, while the annual demand for T-shaped welding studs in steel structure buildings in my country is tens of millions. During the welding process, it is necessary to use a ceramic ring to...

Problems solved by technology

[0003] Since there is no automatic feeding technology for T-shaped welding studs with ceramic rings and no automatic welding torch that can automatically clamp and disengage T-shaped welding studs and ceramic rings, so that the current arc studs for T-shaped welding studs Welding is mainly manual operation, not only low productivity (only about 6 welds per minute), but also low yield, and there are certain safety hazards for operators. Therefore, it is urgent to realize the automatic screwing of T-shaped welding studs in this field. Column welding technology and devices to meet the needs of today's social development
