The invention relates to a polishing device for valve base holes of an air cylinder cover of a marine diesel engine. The polishing device comprises a polishing assembly of an air inlet valve base holeand a polishing assembly of an air outlet valve base hole. The polishing assembly of the air inlet valve base hole comprises a rotation shaft A, wherein a transmission end of the rotation shaft A goes through an air inlet valve base and is in transmission connection to a driving device; a polishing wheel A is disposed on a working end of the rotation shaft A; and the driving device drives the rotation shaft A to drive polishing of the air inlet valve base hole by the polishing wheel A. The polishing assembly of the air outlet valve base hole comprises a rotation shaft B, wherein a transmission end of the rotation shaft B goes through an air outlet valve base and is in transmission connection to a driving device; a polishing wheel B is disposed on a working end of the rotation shaft B; andthe driving device drives the rotation shaft B to drive polishing of the air outlet valve base hole by the polishing wheel B. The polishing device provided by the invention is characterized in that asolution of automatic rotary polishing processing with accurate positioning is used; and processing efficiency and accuracy are high.
Description
technical field [0001] The invention relates to a grinding device for a valve seat hole of a cylinder head of a marine diesel engine, in particular to an efficient grinding device for a valve seat hole of a cylinder head of a marine diesel engine, belonging to the field of marine diesel engines. Background technique [0002] The existing cylinder head intake and exhaust valve seat hole grinding tool is mainly composed of a reamer disc, a rotating handle and a fastening nut. The component is inserted into the center of the cylinder head inlet valve hole or the cylinder head exhaust valve hole, and the reamer disc is manually rotated by using a hand-held rotating handle. Tapered surface for reaming. The existing processing methods have the following problems: (1) The existing tools are operated by manual reaming to repair the tapered surface of the inlet and exhaust valve seat holes of the cylinder head. The labor intensity is very high, the work efficiency is very low, and...
