[0002] Steel components refer to composite steel structure components that can bear and transfer loads and are made of steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-shaped steels that are cold-bent or welded and connected by connectors. The steel component system has the comprehensive advantages of light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution.

[0003] Before being assembled, steel components are generally cut into corresponding sizes and shapes through different steel structures. Therefore, some burrs will appear on the edges of the steel structures after cutting. In order to avoid accidental injury to workers, a burr removal machine is needed to align and grind them to eliminate them. However, most of the existing burr removal machines align and grind through grinding wheels. Therefore, the grinding process is relatively rough, and some smaller burrs still exist, thereby reducing the fineness of burr removal. Secondly, the grinding wheels of existing burr removal machines are basically fixed, so when encountering steel structures of different thicknesses, it is inconvenient to adjust, and the flexibility and scope of use of the burr removal machine are reduced.
