Rudderstock cone fitting method

Abstract

The invention discloses a rudderstock cone fitting method. The method comprises the following steps that the size of a cone hole is measured; the machining size of the cone is modified on a design drawing of the cone according to the cone hole size; the rudderstock is hoisted to a numerical control lathe, and then the modified machining size is guided into a system of the numerical control lathe to machine the cone; the blue matching surface of the cone is colored; the steering engine is moved so that the cone can be inserted into the cone hole, and after the cone and the cone hole are separated, the contact condition of the cone and the cone hole is observed; and the poor contact part of the cone is locally polished. According to the rudderstock cone fitting method, the cone is machined according to the size of the cone hole, the fit degree of the machined cone and the cone hole is high, the fitting allowance of the cone is reduced, and therefore the polishing time of the fitting face is shortened, the machining precision and efficiency of the numerical control lathe are high, and the cone fitting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method for fitting a rudder stock cone. Background technique [0002] The connection between the rudder stock and the steering gear is a keyless conical hydraulic connection. In order to ensure a sufficient fit between the rudder stock and the steering gear, the shipyard needs to match the taper hole of the steering gear in the workshop, and the machining of the taper hole of the steering gear will be affected. Due to the influence of the material and processing accuracy of the steel castings, there is an error between the actual size after processing and the theoretical size of the drawing, so that the contact area between the rudder stock cone and the steering gear hole is insufficient, so that the steering gear hole is colored , insert the rudder stock into the taper hole of the steering gear, mark the position with a circle on the taper hole of the steering gear with less bum...

[0002] The connection between the rudder stock and the steering gear is a keyless conical hydraulic connection. In order to ensure a sufficient fit between the rudder stock and the steering gear, the shipyard needs to match the taper hole of the steering gear in the workshop, and the machining of the taper hole of the steering gear will be affected. Due to the influence of the material and processing accuracy of the steel castings, there is an error between the actual size after processing and the theoretical size of the drawing, so that the contact area between the rudder stock cone and the steering gear hole is insufficient, so that the steering gear hole is colored , insert the rudder stock into the taper hole of the steering gear, mark the position with a circle on the taper hole of the steering gear with less bumps according to the visual inspection results, and brush the part marked with the circle, but the grinding workload of the steering gear generally requires More than half a month, so this processing method has disadvantages such as long processing time and high labor cost
