Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a rear beam positioning welding device for a road roller. Background Art

[0002] When producing the rear beam of a road roller, the positioning and installation problems of welded parts are difficult to solve. Due to the high precision requirements on the workpiece size, it is difficult to ensure the positioning dimensions between the various components of the product during welding and assembly, such as the parallelism, verticality, coaxiality, etc. of the workpiece, and welding deformation is easy to occur. Under normal circumstances, during production, only lines can be drawn manually to straighten the parallelism and a protractor can be used to measure the verticality. When welding the workpiece, it is necessary to align with the drawn line. The welding quality is difficult to ensure and the work efficiency is low.

[0003] Most of the existing rear beam welding equipment has one robot corresponding to one clamping assembly. The front and rear beams to be welded are clamped by the clamping assembly, and then the welding operation is performed by the robot. However, the size specifications of rear beams of different models are different, and the positions of welds are also different. Often there are multiple welds on the same front and rear beams. When the clamping assembly clamps and locks the rear beam, the welder needs to frequently adjust the position of the rear beam so that different welds are aligned with the welding equipment operated by the robot. The operation is very inconvenient, and it is not easy to accurately align the weld position with the welding equipment. After the staff completes welding on one end face of the rear beam, the staff needs to manually flip the rear beam, which results in a large workload and low welding efficiency.
