Method for hole boring fine processing of ship stern shaft tube

Abstract

The fine processing method of hole boring in ship stern shaft tube includes the following measures. Pneumatic grinding wheel rotating together with the stern shaft tube borer and running axially together with the cutter holder for machining the stern shaft tube is installed onto the stern shaft tube borer. Compressed air is conveyed to the pneumatic grinding wheel via the air conveying connector installed onto the stern shaft tube borer, so that the pneumatic grinding wheel grinds the bored hole in the stern shaft tube. The present invention raises the safety and environment protection in the fine machining of stern shaft tube, reduces the labor strength, raise the quality of the machined stern shaft tube and shortens the machining period.

Description

technical field [0001] The invention relates to ship manufacturing and processing, in particular to a method for boring and finishing the ship stern tube capable of effectively controlling the machined size and surface roughness of the ship stern tube. Background technique [0002] At present, the machining of ship stern tubes is carried out by installing a turning tool on the stern tube, and then removing the stern tube from the stern tube, and manually grinding the bored inner wall of the stern tube by the workers holding the wind grinding wheel. finishing. With this finishing method, although the final processing quality can be controlled to a certain extent, the degree of mechanization is too low, which limits the improvement of processing quality; in the whole process of finishing the stern tube, the concentricity of the stern tube can be controlled in a short time It is very difficult to improve the degree, surface finish, roundness and cylindricity, which prolongs th...

Problems solved by technology

With this finishing method, although the final processing quality can be controlled to a certain extent, the degree of mechanization is too low, which limits the improvement of processing quality; in the whole process of finishing the stern tube, the concentricity of the stern tube can be controlled in a short time It is very difficult to improve the degree, surface finish, roundness and cylindricity, which prolongs the processing cycle accordingly; moreover, the finishing process of the stern tube is done by workers drilling in the narrow stern tube and manually grinding with a hand-held wind grinding wheel. Not subject to grinding metal splashes and dust, not only the labor intensity is particularly high, the working environment is poor, the safety guarantee is poor, and the grinding quality cannot be effectively guaranteed
