Example Embodiment

[0022] Example 1:

[0023] Such as figure 1 with figure 2 Shown is the rudder system device to be assembled and welded in the present invention. The rudder system device includes a rudder stock 1 with a rudder stock flange 1-1 at one end. The rudder stock 1 is connected to the rudder through its rudder stock flange 1-1. The rudder blade flange 2-1 of the blade 2 is connected, the rudder flange 1-1 is provided with a positioning column on the lower end surface, the rudder blade flange 2-1 is provided with a positioning stop on the upper end surface, and the positioning column of the rudder flange 1-1 Connect with the positioning stop of the rudder blade flange 2-1; a rudder pin seat 4 is welded on the lower part of the rudder blade, and a rudder pin 5 is installed in the conical hole of the rudder pin seat 4; rudder stock 1, rudder blade 2 and rudder pin The axis of 5 is arranged coaxially.

Example Embodiment

[0033] Example 2:

[0034] The welding rod should be baked before welding, and the rudder blade 2 and the rudder pin holder 4 should be preheated at a temperature of 250℃; the welding should be carried out in the order of vertical welding, butt welding and flat welding, and insulation wool must be used after each welding Cover the welding seam and heat the welding seam to cool it slowly; after the welding is completed, place the rudder system device on the welding tooling of the rudder system device for 12 hours to remove; other features are the same as the first embodiment.

Abstract

The invention discloses a rudder system device assembling and welding method. The method includes A, completing the machining of a rudder stock and blade flange positioning post and a rudder pin seat conical hole; B, welding the blank of a rudder blade flange to the upper portion of a rudder blade; C, turning and milling the rudder flange upper end surface and positioning notch of the welded rudder blade and rudder blade flange; D, installing a rudder pin into the conical hole of a rudder pin seat, fixing the rudder pin to the lower portion of the rudder blade through a plurality of movable clamps, installing the rudder stock and blade flange positioning post in the positioning notch of the rudder blade flange of the rudder blade, and obtaining a pre-assembled rudder system device; utilizing a rudder system device welding tooling to weld the rudder system device. Compared with the prior art, the method has the advantages that the problem that the coaxiality of rudder stock, rudder blade and rudder pin of an existing rudder system device cannot meet the design requirements can be solved.

Description

technical field [0001] The invention relates to the technical field of ship processing, in particular to an assembly and matching welding method for a ship rudder system. Background technique [0002] The rudder system is one of the ship's control devices. According to the fixing method of the rudder, the rudder system can be divided into: the rudder supported by the rudder heel, the semi-suspended rudder and the suspended rudder. Today's offshore anchor tugboats, marine workboats and other marine engineering ships basically use such figure 1 The rudder supported by the rudder heel is shown. The rudder system device of the rudder supported by the rudder heel includes a rudder stock 1 with a rudder stock flange at one end. The rudder blade flange 2-1 is connected, the rudder stock flange 1-1 is provided with a positioning post on the lower end surface, the rudder blade flange 2-1 is provided with a positioning notch on the end face, the positioning post of the rudder stock f...
