An automatic stud welding system for road and bridge expansion joint long sections and large-size round steel

Abstract

The invention discloses an automatic road-bridge telescopic seam long profile and large-size circular steel stud welding system. The system comprises welding mechanical arm mechanisms, opening / closing ceramic ring mechanisms, a guide rail mechanism and ground rail roller frames. The welding mechanical arm mechanisms are arranged on one sides of the ground rail roller frames. The opening / closing ceramic ring mechanisms are arranged on the corresponding positions of the other sides of the ground rail roller frames. The welding mechanical arm mechanisms are further provided with automatic feeding and jacking mechanisms. The ground rail roller frames are provided with long profiles to be welded. The long profiles are positioned precisely through a plurality of profile positioning devices evenly distributed on the ground rail roller frames. The guide rail mechanism is arranged between the ground rail roller frames. The guide rail mechanism comprises two linear guide rails arranged in parallel. The two linear guide rails are provided with a carriage. The carriage conducts reciprocating motion on the linear guide rails on the dependence of a carriage drive device arranged on the carriage. The automatic road-bridge telescopic seam long profile and large-size circular steel stud welding system has the advantages of being reasonable in structure, high in positioning accuracy, even in welding seam, precise to control and the like.

Description

technical field [0001] The invention belongs to the technical field of stud welding equipment, and in particular relates to an automatic stud welding system for road and bridge expansion joint long profiles and large-size round steel. Background technique [0002] A row of large-diameter steel rods needs to be welded at intervals on the surface of special profiles for road and bridge expansion joints. According to national standards, this welding process should be realized by stud welding. At present, there is no automatic stud welding equipment that can provide large-size studs. The current manual stud welding torch, due to the simple structure of the welding torch, is extremely inconvenient to clamp the workpiece, and the production efficiency is low. In addition, due to the manual holding of the torch during the welding process, it is difficult to keep the steel rod perpendicular to the profile, and the welding quality is difficult to be guaranteed. In addition, due to the...

The current manual stud welding torch, due to the simple structure of the welding torch, is extremely inconvenient to clamp the workpiece, and the production efficiency is low. In addition, due to the manual holding of the torch during the welding process, it is difficult to keep the steel rod perpendicular to the profile, and the welding quality is difficult to be guaranteed. In addition, due to the ceramic The deviation between the clamping of the ring and the welding torch causes the center of the stud and the ceramic ring to not coincide, resulting in uneven welds, insufficient welding strength of the steel rod, or even unqualified
