Description

Method for quickly marking center line of T-shaped component of ship body

Technical Field

The invention relates to the technical field of ship manufacturing, in particular to a method for quickly drawing a center line of a T-shaped component of a ship body.

Background

There are a large number of T-members in the hull structure, as shown in fig. 1, which are composed of an upper panel 01 and a lower web 02, and the web 02 is installed below the center line of the panel 01. In the manufacture of such T-shaped members, the midline of the panel is generally first cut and the web is then secured to the panel outside the midline. Currently, workers typically use manual measurement to map the centerline of the panel and weld the web assembly to the outside of the centerline of the panel.

The prior proposal for surveying the center line of the faceplate by manual measurement has the following problems: (1) The manual measurement efficiency is low, a large number of T-shaped components need to repeatedly measure the center line position, and the repeated labor occupies much time of workers; (2) The manual measurement has certain errors and probability of human errors, which affect the assembly precision and the assembly effect.

There are some existing tools capable of assisting in drawing a center line, such as CN201010174914.1, which discloses a center line scribing device, including a support, positioning pillars and center line sliding cones at two sides, which are slidable and lockable with respect to the support, wherein the two positioning pillars and the center line sliding cone are parallel to each other, the center line sliding cone is located at a center line position of the two positioning pillars, the positioning pillars are in a step shaft structure, the center line sliding cone is composed of a middle shaft and cone scribers at two ends, when the device assists in positioning and scribing, the positioning pillars at two sides are used for clamping and positioning a workpiece, and then the device is moved along a scribing direction to draw a center line. The center line scribing method can improve the center line scribing efficiency and precision. However, when the method is used for positioning and scribing the center line of the panel of the T-shaped component, the panel of the T-shaped component is thin, so that the problem that the clamping angle is not perpendicular enough when the two positioning columns are clamped and positioned by the scribing method is easily caused, and the problem of center line position deviation is caused.

Therefore, it is desirable to design a tool capable of assisting to scribe the center line of the T-shaped member more precisely, so as to solve the above problems.
