Description

Back side marking tool

Technical Field

The utility model relates to a boats and ships ocean engineering instrument technical field especially relates to reverse side marking tool.

Background

During the production and construction of the ship, a numerical control cutting machine is adopted to cut steel plates to produce plate parts. The numerical control cutting machine can spray lines on the plate to mark the positions of other parts to be subsequently installed on the plate. However, the numerical control cutting machine can only spray lines on one surface of the steel plate, and can only manually mark lines on the back surface of the plate when being installed on an assembly line of other parts on the other surface of the plate.

In actual production, a cutting machine is usually used for marking the back side of the steel plate on the front side of the steel plate, and then a line-pulling plate is used for manually marking the back side of the steel plate according to the position of the front side marking. The line-pulling plate is a wooden cuboid, the middle part of the line-pulling plate is carved empty, the shape of the line-pulling plate is similar to that of a clamp, the line-pulling plate can be clamped at the edge of a steel plate, and the condition of front scribing is reflected to the reverse side of the steel plate. The problems of the wire pulling plate are 2: 1. the thickness of the middle hollowed part is the corresponding thickness of the steel plate. Therefore, different wire pulling plates are needed for the steel plates with different thicknesses. The thickness of the steel plate practically used in a shipyard is from 6mm to 100mm, so that the corresponding wire pulling plates need to be prepared, and the back-and-forth switching is troublesome in use. 2. The wire shifting plate can only be perpendicular to the thickness of the steel plate for wire shifting. When the assembly lines are close, the assembly lines of the front parts and the assembly lines of the back parts can not be distinguished if the assembly lines of the front parts and the assembly lines of the back parts are simultaneously drawn on the front side of the steel plate. Because when 2 lines are close together, the lines ejected from the cutter will partially overlap, losing precision. Therefore, the assembly line of the reverse parts cannot be drawn, and the reverse drawing can be manually performed only according to the data marked by the design department.
