Description

Technical Field

[0001] The utility model relates to the technical field of industrial processing equipment, in particular to a weld scar grinding and milling machine. Background Art

[0002] The design principles of steel structure welded joints should mainly consider the convenience of welder operation to obtain dense and high-quality welds, minimize component deformation, reduce the value of welding shrinkage stress and its uneven distribution, and especially avoid local stress concentration. During the welding process of steel structures, due to the operator's experience or other objective factors, it is very easy to cause stress concentration in the weld during welding. When the components are in operation, they will be subjected to variable loads, impact loads and vibration loads, which can easily cause fatigue and failure, or even worse, the appearance of slag and weld nodules on the surface. In addition, during the processing of steel structures, some residues and burrs left after surface processing are difficult to remove.

[0003] At present, the only machines used by various companies to deal with these problems are grinding machines and angle grinders. These two types of machines are time-consuming and inefficient in dealing with these problems and cannot solve the problems at one time. The surface flatness of the treated components is not enough and the surface is relatively rough. In addition, the stress at the weld joints cannot be effectively reduced, which greatly increases the quality risks of the components and indirectly increases the cost of factory production. At this time, the integrated processing of steel structure grinding and milling is particularly meaningful. Utility Model Content
