Guide plate device of steel pipe polishing machine

The guide plate device of the steel pipe polishing machine of the utility model is fixed on a base at the lower part of the gap of a grinding wheel and a guiding wheel axial line. The utility model is characterized in that the guide plate device has a divided structure, the upper part of the guide plate device is provided with a non-metal guide plate, and the lower part of the guide plate device is provided with a metal bracket. The guide plate is a rectangular plate whose thickness is smaller than the diameter of the steel pipe and length is bigger than the width of the grinding wheel. A slot hole is arranged at the upper part of the anomalous bracket for fixing the guide plate, and a metal plate with two strip-shaped slot holes is arranged at the bottom of the bracket for fixedly connecting the bracket and the base. When working, the steel pipe is supported by the guide plate, which makes the surface of the steel pipe normally ground and polished. When the highest point of the guide plate falls down to a certain position (abrading), the strip-shaped slot holes of the bracket are used to regulate the height of the guide plate. The utility model has the advantages of reasonable design, convenient production, easy assembly, and no need for damaging the original entire structure. The processing of the guide plate has low cost, high using efficiency and convenient exchange, satisfying the normal operation of the steel pipe polishing machine.
