Background
The pinch roll polishing machine is used for cleaning scrap iron, iron scales and other impurities on the surface of the pinch roll, and polishing the surface of the pinch roll to improve the surface quality of a steel plate; the pinch roll polishing machine is arranged on a hot rolling pinch roll rack, is in a high-temperature environment inconvenient to maintain, and has a very limited installation space. The pinch roll polishing machine mainly comprises a fixed beam, a movable swing frame, a sliding rod, a transverse bearing seat, a grinding head part, a pressing cylinder, a transverse cylinder and the like. The two ends of the movable swing frame are provided with slide bars which are arranged in linear bearing holes of the transverse bearing block. When the polishing machine works, the sliding rods at the two ends of the movable swing frame do transverse movement along the axial direction of the transverse bearing seat to drive the grinding head component arranged on the movable swing frame to transversely move, so that the surface of the roller is polished; when the polishing machine is started and stopped, the sliding rods at the two ends of the movable swing frame rotate around the inner hole of the linear bearing of the transverse bearing seat, so that the grinding head is pressed or separated from the roller. When the pinch roll polisher polishes, the movable swing frame makes high-frequency reciprocating linear motion to drive the grinding head arranged on the movable swing frame to polish the pinch roll rotating at high speed along the axial direction of the pinch roll, and the movable swing frame is impacted and vibrated by high frequency; the distance between the sliding rods at the two ends of the movable swing frame is larger, and the sliding rods at the two ends of the movable swing frame must be concentric in order to ensure smooth and flexible transverse movement and rotation of the movable swing frame.
