Automatic welding production line

Abstract

The invention discloses an automatic welding production line, and belongs to the technical field of welding production. The automatic welding production line comprising a base, a supporting piece installed on the base, a driving chain wheel installed on the base, a driven chain wheel installed on the base, a chain arranged on the driving chain wheel and the driven chain wheel in a sleeving mode, a driving motor connected with the driving chain wheel, a lifter installed on the base, a rail base, a portal frame installed on the rail base, a welding machine mounted on the portal frame and a laser positioning tracker; the upper surface of the supporting piece is provided with a chain groove allowing the chain to shuttle, the chain groove penetrates through the supporting piece in the moving direction of the chain, the lifter is provided with a telescopic part used for driving the chain to be switched between the conveying position and the no-load position, and when the chain is located at the conveying position, the chain is located outside the chain groove; and when the chain is in the no-load position, the chain is located in the chain groove, and the to-be-welded piece is located on the supporting piece. The side wall of an open wagon can be automatically welded, the welding efficiency and the welding quality are high, and the labor intensity of workers and the welding cost are reduced.

Description

technical field [0001] The invention relates to the technical field of welding production, in particular to an automatic welding production line. Background technique [0002] At present, domestic rail transit freight car open car welding basically adopts manual methods, combined with a small number of mechanical welding machines, the degree of automation is low, and its welding efficiency and welding quality mainly depend on the welder's skills, psychological state and sense of responsibility, and it is difficult to guarantee welding efficiency and welding quality . The main manifestations are as follows: 1. The welding of the side wall requires a large number of welding operators, and the labor intensity is high; 2. The welding of the side wall is dominated by manual operations, the welding process is poor in consistency, the welding parameters are unstable, and the welding quality is difficult to guarantee; 3. The welding operation environment is poor , The smoke and dus...

[0002]At present, the welding of domestic rail transit freight car open car basically adopts manual method, combined with a small number of mechanical welding machines, the degree of automation is low, and its welding efficiency and welding quality mainly depend on the welder's ability Skills, psychological state and sense of responsibility make it difficult to guarantee welding efficiency and welding quality

The main manifestations are as follows: 1. The welding of the side wall requires a large number of welding operators, and the labor intensity is high; 2. The welding of the side wall is dominated by manual operations, the welding process is poor in consistency, the welding parameters are unstable, and the welding quality is difficult to guarantee; 3. The welding operation environment is poor , The smoke and dust pollution in the welding process is large, which endangers the occupational health of welding personnel; 4. The workpiece transmission, positioning, fixing, welding machine movement, and welding seam search related to side wall welding are all done manually, with high randomness and poor consistency

5. The side walls to be welded are manually assembled and assembled, and the dimensional accuracy and consistency are poor. The welding process needs to be manually adjusted to adapt to the actual state of the workpiece
