Background Art

[0002] A magnetic scale is a displacement sensor that measures the actual direction and distance of movement of the object being measured through the relative displacement between the sensor body and the movable magnetic ring. In a steel mill, a magnetic scale is provided on the hydraulic cylinder of the rolling mill, and the magnetic scale is installed at the bottom of the hydraulic cylinder housing. When removing the magnetic scale, the support roller blocking the outside of the magnetic scale needs to be removed, and then the staff enters the rolling mill and uses a hexagonal socket wrench to remove the magnetic scale. Due to the small operating space, it is inconvenient for the staff to operate, and the hexagonal socket wrench will damage the magnetic scale body if the force is not applied correctly. Manual removal of the magnetic scale is inefficient and labor-intensive, so a disassembly auxiliary device is needed to assist the staff in efficiently disassembling the magnetic scale.
