Matching detection device for rudder arm and rudder blade and manufacturing method for rudder arm and rudder blade

Abstract

A matching detection device for a rudder arm and a rudder blade and a manufacturing method for the rudder arm and a rudder blade, the detection device includes a tooling plate fixed on the rudder arm and a measuring plate that rotates around the rotation axis of the tooling plate, and the measuring plate can be simulated as a rudder blade Swinging on the rudder arm, the detection device has a simple and portable structure, requires less measurement data, greatly simplifies the detection work, and effectively improves the detection accuracy and reduces personnel requirements; It can solve the problem of collision between the rudder arm and the rudder blade when it is loaded in the dock or on the berth, improve the efficiency of rudder blade installation and rudder swing debugging, and avoid the extended casting quality repair work caused by trimming and carbon planing castings during the loading stage , UT flaw detection, ship inspection and other series of work, greatly shortening the cycle of the slipway and dock.

Description

technical field [0001] The invention relates to a detection tool in shipbuilding, especially a device for detecting the matching degree between a rudder arm and a rudder blade, and a detection method using the device. Background technique [0002] The rudder arm is an arm-shaped member used to support the semi-suspended rudder in a ship, and the rudder blade is the body that generates the rudder force. In the ship structure, the rudder arm is fixedly installed on the bottom of the outer plate of the ship, and its upper and lower ends facing the stern are respectively provided with protruding rudder knobs, and the rudder blades are rotatably installed on the rudder knobs through rudder pins superior. If the gap between the rudder arm and the rudder blade is insufficient, the two will collide during the rotation of the rudder blade, that is, the top of the rudder blade between the upper and lower rudder knobs will collide with the rudder arm, commonly known as top collision. ...

AI Technical Summary

Problems solved by technology

[0004] This detection method can roughly judge whether there will be a top collision between the rudder arm and the rudder blade during the production stage, but the measurement is difficult, the data needs to be recorded, and the operator’s experience and analysis ability are relatively high. Even so, the comparison between the recorded data and the theoretical value is still very difficult and the accuracy is low. In addition, this method requires the cooperation of multiple operators to implement, resulting in high requirements for both the quality and quantity of personnel.
