Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shipbuilding, in particular to a groove compensator. BACKGROUND

[0002] Modern shipbuilding implements precision management, and the edges of sections and plates are all without allowance, and at least one edge is opened with a groove. Each cutting is fine to the extreme, and waste of materials is avoided as much as possible. When the groove surface is marked, the groove size needs to be calculated into the marking length, so as to calculate accurate cutting data.

[0003] Nowadays, workers mostly rely on estimation or a top ruler when marking the groove surface, and cannot achieve accurate measurement, which makes the measurement result not accurate enough, thereby causing shortage or waste of materials. The current measurement method relies on a ruler to approximately approach the starting end of the measurement position, and then measurement is performed. Such a measurement method is not accurate, and in addition, the person holding the end of the ruler may cause hand tremor due to long-time holding of the ruler, which further affects the measurement data. After the approximate data is measured by the existing method, the worker first draws a mark on the steel with a marker pen at the approximate data on one side of the steel, and then repeats the above operation to draw another mark on the other side of the steel. Then, the worker approximately draws a straight line with the marker pen. Such an operation not only increases the workload of the worker, but also increases the difficulty of the worker in cutting the steel. Because the previous operations are all assisted by the approximately straight lines, the worker is misled by the straight lines drawn by the marker pen, which causes the cutting to deviate from the predetermined position, and the cut straight line does not meet the requirements, thereby causing secondary rework.

The present application solves the problems of the prior art that the existing measurement method can only measure approximate data, the marking marks need to be marked on both sides of the steel to increase the workload, and the straight line connected by the marks is too arbitrary to increase the difficulty of subsequent cutting, and the straight line connected by the marks at will by the worker is easy to deviate from the predetermined position, thereby causing the quality to be not good enough and causing secondary rework.
