TECHNICAL FIELD
[0001] The present application relates to the technical field of grinding machines, and particularly relates to a roller on-line grinding mechanism. BACKGROUND
[0002] A roller is a main working component and tool for continuously plastic deformation of metal on a rolling mill. The roller mainly comprises a roller body, a roller neck and a shaft head. The roller body is a middle part of the roller actually participating in rolling metal. The roller body has a smooth cylindrical surface or a surface with rolling grooves. The roller neck is installed in a bearing, and the rolling force is transmitted to the mill stand through the bearing seat and the pressing device. The driving end shaft head is connected with the gear seat through a connecting shaft, and the rotating torque of the motor is transmitted to the roller. The roller can be arranged in a two-roller, three-roller, four-roller or multi-roller form in the mill stand.
[0003] During the rolling process, the roller body part of the roller may appear problems such as sticking iron and rough surface. In order to ensure the quality of the rolled steel, it is often necessary to stop and maintain. The commonly used maintenance means is to manually use a grinding machine to grind the roller body, which wastes time and increases labor.
