Technical Field

[0001] The utility model relates to the technical field of sandblasting, in particular to a sandblasting device for a welding position of a product. Background Art

[0002] Sandblasting is a processing method that uses compressed air as a power source to form a high-speed jet beam to spray the material at high speed onto the surface of the workpiece to be processed, so that the surface of the workpiece can obtain a certain degree of cleanliness and different degrees of roughness, so that the mechanical properties of the workpiece surface are improved, thereby improving the fatigue resistance of the workpiece. After the metal workpiece is produced, in order to extend its service life, it is usually necessary to use sandblasting equipment to blast it. Before the sandblasting operation, the workpieces are placed on the conveyor belt in sequence, and the spacing between workpieces of different sizes will also be different.

[0003] However, the nozzles of some sandblasting equipment are mostly fixed, and the distance between the nozzles cannot be adjusted according to the gap between the workpieces. This will cause inaccurate positioning of the nozzles and the workpieces, thereby reducing the effect of sandblasting and requiring secondary rework, wasting a lot of time. For this reason, we propose a product welding sandblasting equipment to solve the above problems. Summary of the invention
