Ship segmented outer plate and aggregate positioning method

Abstract

The invention discloses a ship segmented outer plate and aggregate positioning method. The method comprises the following steps: designing and cutting to obtain a tool plate, scribing lines on the tool plate, including an auxiliary half-width line and an auxiliary height line, then assembling a jig frame base surface and a longitudinal wall plate, mounting the tool plate by taking the jig frame base surface and the longitudinal wall plate as reference, checking the verticality of the tool plate relative to the jig frame base surface, and finally hoisting and welding aggregates and an outer plate. According to the invention, the tool plate is provided with an outer edge attached to the surface of the inner side of the outer plate and a through hole allowing aggregate to penetrate through. Therefore, the outer plate and the aggregate can be quickly positioned; the tool plate is positioned through the auxiliary half-width line and the auxiliary height line; compared with a traditional construction method, the positioning difficulty is lowered, the positioning precision is improved, accurate and rapid positioning of the ship segmented outer plate and the aggregate is achieved, the production efficiency is improved, the positions of the outer plate and the aggregate are fixed through the tool plate, welding deformation of the outer plate and the aggregate is reduced, and the methodis applied to the field of ship manufacturing.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a method for locating a segmented outer plate and a frame of a ship. Background technique [0002] In the process of ship construction, the section with larger outer plate line shape and relatively empty structure accounts for about 30% to 40% of the whole ship, and this type of section is the most difficult to control the accuracy and quality of the entire ship section construction process The production cycle and labor cost are also the longest, and the root cause of this problem is that the precise assembly and positioning of curved outer plates and longitudinal bulk aggregates is more difficult. At present, in the production process, construction personnel mainly use partial structural relative data to locate the outer panels and aggregates. During the positioning process, they need to be measured and rechecked one by one. The above-mentioned construction method of measuring while...

[0002] In the process of ship construction, the section with larger outer plate line shape and relatively empty structure accounts for about 30% to 40% of the whole ship, and this type of section is the most difficult to control the accuracy and quality of the entire ship section construction process The production cycle and labor cost are also the longest, and the root cause of this problem is that the precise assembly and positioning of curved outer plates and longitudinal bulk aggregates is more difficult

At present, in the production process, construction personnel mainly use partial structural relative data to locate the outer panels and aggregates. During the positioning process, they need to be measured and rechecked one by one. The above-mentioned construction method of measuring while installing has the following problems: low efficiency and large cumulative errors , and it is easy to deform after welding, resulting in the workload of rework
