Description

Technical Field

[0001] The invention relates to the technical field of truss riveting and welding, and in particular to a truss standard section rapid riveting and welding tool and method. Background Art

[0002] A truss is a geometrically invariant structure consisting of a triangular frame made of straight rods.

[0003] Riveting is a type of electric welding. The usual welding method is to penetrate the object to be welded with a welding rod. It is generally used to weld relatively thick metals.

[0004] At present, when performing riveting and welding operations on standard sections of trusses, it is necessary to adjust the angles of the two trusses and butt them into place, and then use an electric welder to perform riveting and welding operations on the welding points. Since there are usually four welding points between the standard sections of two trusses, personnel are required to perform spot welding reinforcement around the four welding points. This process usually takes a lot of time, which reduces the riveting and welding efficiency. At the same time, the existing automatic riveting and welding equipment is difficult to adaptively adjust according to the size specifications of the standard sections of the trusses, and it is often necessary to replace the matching riveting and welding tooling, which is very inconvenient and affects the continuity of the riveting and welding operations of the standard sections of the trusses.

Finally, start the external electric welding machine, and use four groups of electric welding heads to perform riveting operations on the four welding points between the two standard truss sections. After the riveting is completed, the conveyor belts in the first transmission platform and the second transmission platform are controlled to have the same transmission direction, that is, to the right, to transport the riveted and welded standard truss sections.
