Problems solved by technology

[0002] In the process of shipbuilding, it is usually necessary to install the accessories at the predetermined position. At present, after the accessories are installed at the predetermined position, it is usually necessary to use a ruler to measure the distance between the reference position and the predetermined position to realize the measurement of the installation error. However, using a ruler to measure installation errors has the problem of relatively large errors, which is extremely unfavorable for the measurement of installation errors

Abstract

The invention provides a measurement method, and relates to the field of ship manufacturing. The measurement method comprises the following steps: carrying out an error confirmation step: obtaining an allowable installation error of an installation position relative to a reference position based on connection strength requirements of a first plate, a second plate and a third plate; carrying out a calibration step: to be specific, acquiring the position of the third plate, and setting the reference position to be deviated by a calibration distance relative to the third plate in the direction deviating from the plate face of the third plate; carrying out a measuring step: to be specific, arranging a measuring tool, attaching one side part of the measuring tool to one of the first plate and the third plate, and carrying out measuring together with the side part by utilizing a part, which is separated from the side part, of the measuring tool so as to obtain an actual distance between the mounting position and the reference position; and calculating whether deviation of the actual distance from the calibrated distance satisfies allowable installation error. According to the measurement method provided by the invention, the problem that the error is relatively large when the distance between the reference position and the installation position is measured is solved, and accurate measurement of the installation error is realized.

Description

technical field [0001] The present application relates to the field of shipbuilding, in particular to a measuring method. Background technique [0002] In the process of shipbuilding, it is usually necessary to install the accessories at the predetermined position. At present, after the accessories are installed at the predetermined position, it is usually necessary to use a ruler to measure the distance between the reference position and the predetermined position to realize the measurement of the installation error. However, using a ruler to measure the installation error has the problem of relatively large errors, which is extremely unfavorable for the measurement of the installation error. Contents of the invention [0003] In view of this, the present application provides a measurement method, through the error confirmation step to determine the allowable installation error between the installation position of the first plate and the reference position, through the ca...
