Linear welding device

Abstract

The invention discloses a linear welding device. The linear welding device comprises a rack, two panels, a transverse drive assembly, a welding gun traveling mechanism, a pushing assembly and fastening assemblies; the rack is arranged on the horizontal plane; the panels are horizontally arranged on the top of the rack; one end of each panel is fixed to the upper portion of the rack, and the otherend of each panel outwards extends to the outer side of the rack; the two panels are arranged in parallel in a spaced mode, and a strip-shaped welding tank is formed between the two panels; workpiecesare arranged on the lower portions of the panels; the transverse drive assembly is arranged on one side of the welding tank; the welding gun traveling mechanism is connected with the output end of the transverse drive assembly; the pushing assembly is arranged on the lower portion of the rack; and the fastening assemblies are arranged on the outer ends of the panels so as to fasten and fix the workpieces from the outer side. The linear welding device has the function of fine adjustment of the mounting position of a welding gun, the operation steps are simplified, the welding efficiency and welding accuracy are improved, and by adoption of a receding groove and the automatic workpiece pushing and fastening structure, the workpieces positioning precision is effectively improved, and the situation that other portions of the workpieces are welded due to errors is avoided.

Description

technical field [0001] The invention relates to the field of welding, in particular to a linear welding device. Background technique [0002] In industrial production, there are often linear welding requirements, such as corner seam welding of large transformer shells, straight seam welding of large cylinders, straight seam welding of solar water heater cylinders, straight seam welding of steel strips on production lines, H-shaped steel Welding, etc., the welding parts are all linear structures. The traditional way is to complete the welding process in which the above welding parts are linear structures through a straight seam welding machine. The straight seam welding machine is a straight line that realizes welding workpieces through automation and mechanization Automatic welding equipment that automatically completes the weld; it can replace labor in large quantities, greatly improve production efficiency and welding quality, reduce labor costs, and improve the working en...

[0002] In industrial production, there are often linear welding requirements, such as corner seam welding of large transformer shells, straight seam welding of large cylinders, straight seam welding of solar water heater cylinders, straight seam welding of steel strips on production lines, H-shaped steel Welding, etc., the welding parts are all linear structures. The traditional way is to complete the welding process in which the above welding parts are linear structures through a straight seam welding machine. The straight seam welding machine is a straight line that realizes welding workpieces through automation and mechanization Automatic welding equipment that automatically completes the weld; it can replace labor in large quantities, greatly improve production efficiency and welding quality, reduce labor costs, and improve the working environment of welders; however, the traditional straight seam welding machine has the following defects in the actual welding process: 1. The welding torch adopts a fixed installation structure, and the position cannot be adjusted after the assembly is completed. Since the part to be welded on the workpiece is a seam-like structure with a small width, the installation accuracy of the welding torch cannot be controlled, and welding errors are easy to occur. The seam welding machine can only be repeatedly verified and adjusted by reassembling the welding torch, which is cumbersome and time-consuming; 2. Since the part to be welded on the workpiece is a seam-like structure with a small width, the error caused by the movement of the welding torch or the assembly error of the workpiece during the welding process The welding position is deviated, and the welding torch is directly welded on other parts of the workpiece, resulting in the scrapping of the workpiece; 3. The assembly of the workpiece to be welded by the traditional straight seam welding machine is complicated and the positioning accuracy is poor
