Embodiment Construction

[0043] Such as Figure 1-7 As shown, the present embodiment adopts the following technical solutions: 1, the method for checking the line shape of the shroud is characterized in that, comprising the following steps:

[0044] A. Prepare the measurement sample 1 and measurement scale 8 shown

[0045] The corresponding scale value 9 needs to be marked on the measuring scale 8;

[0046] B. Adjust the level of the shroud

[0047] Use the stand to adjust the shroud so that the upper face of the shroud is level;

[0048] C. Find the axis

[0049] Let the plumb line hang down from the grid;

[0050] Measure the distance from the plumb line to the inner diameter of the nozzle of the shroud, and find the axis of the shroud by moving the stand;

[0051] When the plumb line is centered on the nozzle, mark the center point on the floor with a chalk tape and marker;

[0052] D. Select the measurement location and mark it

[0053] Mark the position to be measured on the shroud;

Abstract

The invention discloses a bulb rudder linetype inspection method, and the bulb rudder linetype inspection method comprises the following steps: A. a measuring sample plate and a measuring ruler are prepared, wherein corresponding scale values are required to be marked on the measuring ruler; B, the bulb rudder is adjusted horizontally, wherein the bulb rudder is adjusted through a frame, so that the upper end surface of the bulb rudder is horizontal; C, an axis is found, wherein a plumb line is vertically fall from a grid, a distance between the plumb line and the inner diameter of a bulb rudder nozzle is measured, and the axis of the bulb rudder is found through a movable frame; a center point is marked on the floor by using a chalk tape and a marking pen when the plumb line is positionedin the center of the nozzle; D, a measurement position is selected and marked, and a position needing to be measured is marked on the bulb rudder; and E, the linetype is measured, and a test sample plate is arranged at the position needing to be measured; the structure is simple and practical, the operation is convenient, and the measurement precision is improved, so that the product quality is improved, and the operation practicability of the bulb rudder linetype inspection method can be greatly improved.

Description

Technical field: [0001] The invention belongs to the field of line type inspection of a wind deflector, in particular to a line type inspection method of a wind deflector. Background technique: [0002] Ship fittings dome, also known as dome cap rudder, refers to a rudder with a streamlined dome at the center of the rudder blade facing the axis of the propeller. For a dome rudder, the size of the dome should be the same as the propeller hub Matching, shroud rudders improve water flow behind the propeller, resulting in increased thrust and reduced stern vibration. [0003] There are currently two types of linetype inspection methods on the market: [0004] Method 1: use a line model inspection, cut the line model with a laser, stick the model on the curved surface, and measure the distance between the model and the curved surface. The error of the data measured by this inspection method is relatively large, especially the overall deviation of the line cannot be tested; [...
