Description

Technical Field

[0001] This utility model relates to a grinding device, specifically a surface grinding device for steel structure machining and production, belonging to the technical field of grinding devices. Background Technology

[0002] Steel structure machining is a process that uses specialized equipment to precisely process steel through cutting, drilling, welding, bending, and other operations. It can manufacture steel into components that meet engineering standards and is widely used in fields such as construction, bridges, and machinery manufacturing. It is a core link in ensuring the precision and stability of steel structure products.

[0003] Grinding is a process that uses tools such as grinding wheels and sandpaper to grind and polish the surface of a workpiece. It can remove burrs, rust, and processing marks, improve surface smoothness and precision, and lay the foundation for subsequent painting, assembly and other processes. It is commonly used in the processing of metals and wood.

[0004] For narrow gaps in steel structures, existing tool heads are too thick to reach and grind effectively. Burrs on steel structures are difficult to remove completely with existing tools, and they easily scratch the surrounding area. Uneven tool force at weld points results in poor precision, slows down efficiency, and affects the subsequent quality of the steel structure. Therefore, a surface grinding device for steel structure machining is proposed. Utility Model Content

[0022] Please refer to this carefully. Figure 3 and Figure 4 The square rod 301 is slidably connected inside the square hole linear bearing 307. The square rod 301 is made of metal, and the square hole linear bearing 307 is also made of metal. The square hole linear bearing 307 is fixed on the top shell 101, and the square rod 301 slides inside it.
