Description

Technical Field

[0001] The utility model relates to the technical field of roller grinding, and more specifically, to a roller grinding device. Background Art

[0002] Rollers are the main working parts and tools on a rolling mill that cause continuous plastic deformation of metal. People usually use the pressure generated by a pair or a group of rolls rolling to roll steel. Rollers mainly bear the dynamic and static loads during rolling, wear and temperature changes. Rollers are mainly composed of three parts: roll body, roll neck and shaft head. When preparing rolls, grinding devices are required to perform fine processing on the produced rolls.

[0003] When the roller surface is ground, it needs to be fixed and clamped. At present, in order to better grind the roller surface, a driving motor is often set on one side and a rotatable shaft is set on the other side. A fixed clamping device is set between the shaft and the driving motor to fix the roller. The gravity of the roller will be borne by the motor and the shaft, resulting in instability in the process of the motor driving the roller to rotate, thereby affecting the grinding flatness of the roller surface and the existing horizontal movement process of the cutting knife. The grinding operation is completed by driving the movement of the existing cutting knife with a single screw rod. The use of a single screw rod makes the movement of the cutting knife unstable, thereby affecting the grinding effect. Utility Model Content
