Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a device for grinding slag pores of metal castings. Background Art

[0002] Metal casting is a process of melting metal into a liquid that meets certain requirements and pouring it into a mold, and then cooling, solidifying, and cleaning to obtain a casting with a predetermined shape, size, and performance. In the metal casting production project, slag pores may appear in the metal casting due to process problems, affecting the quality of the casting. Therefore, when slag pores appear in the casting, it is necessary to treat the slag pores by repair welding. After the repair welding is completed, the repair welding part needs to be polished. When the metal casting is polished, the casting needs to be clamped and fixed. However, the shapes of metal castings are different, including plate-shaped, circular and other shapes. However, the workbench is generally fixed with claws. When the sphere needs to be fixed, it needs to be supported by hand, or the workbench with a spherical clamp needs to be replaced, so the casting needs to be moved many times, making the polishing and fixing of the casting inconvenient.
