Grinding machine special for support roller of rolling mill

Abstract

The invention discloses a grinding machine special for a support roller of a rolling mill. The grinding machine comprises a machine body, wherein a lug boss is arranged on one side of the machine body; a crossed sliding table is arranged on the lug boss; a grinding wheel mechanism is arranged on a workbench of the crossed sliding table; a numerical control turntable is vertically arranged in the center of the machine body; an auxiliary turntable for arranging a workpiece to be machined is arranged on a tabletop of the numerical control turntable; the workpiece to be machined on the auxiliary turntable is flush with the grinding wheel mechanism; parallel guide rails A and B are arranged on the two sides of the numerical control turntable respectively; hydraulic cylinders A and B are correspondingly and vertically arranged in the guide rails A and B respectively; piston rods of the hydraulic cylinders A and B are arranged upwards; a guide wheel frame is arranged above the piston rods of the hydraulic cylinders A and B; a guide wheel is arranged on the guide wheel frame; the guide wheel frame is positioned over the numerical control turntable. According to the grinding machine, the problem of incapability of a current ordinary grinding machine in grinding the outer peripheral surface of the support roller of the rolling mill is solved.

Description

Technical field [0001] The invention belongs to the technical field of numerical control equipment, and relates to a special grinding machine for supporting rollers of a rolling mill. Background technique [0002] The rolling mill rolls the steel plate to make the surface of the steel plate smooth and even in thickness. The rolling mill support roller is a key component of the rolling mill, which plays a decisive role in the quality of the steel plate. The supporting rollers of the rolling mill are installed between the three-layer partitions. Long-term work will cause the surface of the rollers to wear, resulting in uneven surface, resulting in uneven thickness of the steel plate and rough surface, so the rollers must be ground. According to the grinding principle, the roller grinding process belongs to the cylindrical grinding, but because the roller is equipped with the bearing itself and cannot rotate, it needs to be driven by the guide wheel. Because the roller and the part...
