Description

Technical Field

[0001] The utility model relates to the technical field of cylinder workpiece processing, and more specifically to a cylinder welding surface sandblasting treatment device. Background Art

[0002] After the processing of the cylindrical workpiece is completed, more impurities will be generated on its surface. At the same time, when the cylindrical workpiece is welded, some impurities will remain at the welding point. When it is subsequently processed, it is necessary to perform sandblasting on its surface and process the surface of the cylinder to ensure the quality of the cylinder processing. At present, when the sandblasting device processes the cylinder, it is necessary to fix the cylinder inside the sandblasting device and perform sandblasting on it.
