Embodiment Construction

[0040] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] A preferred embodiment of the tooling for fast centering of a stern tube device of the present invention, such as Figure 1 to Figure 21 As shown, the tooling for quick alignment of the stern tube device includes a light target frame and a centering component. The centering component is arranged on the light target frame, and the light target frame is used for supporting and fixing in the inner wall of the stern tube.

[0042] The optical target frame includes a fixed frame 1, an outer frame 2, a middle frame 3 and an inner frame 4. The fixed frame 1 is used to be fixed on the inner wall of the stern tube. The fixed frame 1 is the supporting base of the light target f...

Abstract

The invention relates to the technical field of ship construction, and discloses a stern tube device quick centering tool which comprises a light target frame and a centering assembly. The light target frame comprises a fixing frame, an outer support, a middle support movably assembled on the outer support in the first direction and an inner support movably assembled on the middle support in the second direction. A center hole is formed in the inner support, the centering assembly comprises a rotating shaft rotationally assembled in the center hole, a centering rod connected with the rotating shaft and a dial indicator arranged on the centering rod, and a target center is further coaxially arranged on the rotating shaft. An operator rotates the rotating shaft to drive the dial indicator to rotate through the centering rod, after the dial indicator rotates to the upper, lower, left and right positions, the difference values of all the positions are compared, the outer support is adjusted to move in the first direction, the inner support is adjusted to move in the second direction till the reading difference value of the dial indicator is smaller than or equal to 0.01 mm, and the center of the target center is the center of the stern tube. The tool can be adjusted while the numerical value is observed, so that the centering workload is reduced, the measurement error is reduced, and the centering efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a tool for quickly centering a stern tube device. Background technique [0002] The stern tube is an important structural part of the ship's shafting system. It is arranged on the surrounding cloth of the ship for the stern shaft of the ship to pass through, and has the function of supporting and sealing the stern shaft. The stern tube needs to be centered during installation, and the tolerance requirements are relatively high, so as to ensure that the tail shaft can pass through. [0003] The centering of the stern tube device in the existing shaft system lighting is to place two light target frames on the straight line of the front and rear flanges of the stern tube respectively, install the bull's-eye on the light target frame, and use the inner card to measure the distance from the bull's-eye to the center of the stern tube. The upper, lower, left, and right distances o...
