CYLINDER INSIDE SURFACE BUFFING APPARATUS

摘要

The apparatus performs the buffing of the cylinder inner face with a constant pressure irrespective of the length of a rod shaft. It comprises a fixed shaft(3) combined with a buffer wheel(3c); a protrusion(3') having a rectangular hole and formed on an end of the fixed shaft(3); a rod shaft(2) feeding the buffer wheel(3c) according to the inner face of the cylinder; flanges(2',2") formed on an end of the rod shaft(2) and having holes(2a,2b) correspondent to the rectagular hole of the protrusion(3'); a guide pin(4) making the flanges(2,2') rotatably combined with the protrusion(3').
