Line-drawing device of wave-proof board

Abstract

The invention discloses a line drawing device of a wave-proof board, which comprises a positioning assembly and a rotating shaft which are fixed in a round tube. The rotating shaft penetrates through the center of the positioning assembly and rotates relative to the positioning assembly, an extending rotating arm is fixed at one end of the rotating shaft exposed out of the round tube, a rotatable laser emitting assembly is arranged at one end of the rotating arm, and laser lines emitted by the laser emitting assembly, rotating arm central lines and rotating arm central lines are on the same plane. The line-drawing device uses the laser rectilinear propagation principle, can adjust laser to be at any angles through a laser angle adjusting function, can adjust the rotating shaft to a required position through a rotating shaft central adjusting bolt and can enlarge or narrow a line drawing range through a laser position adjusting function.

Description

technical field [0001] The invention belongs to the field of line drawing, and in particular relates to a line drawing device for complex curved surfaces of anti-wave boards. Background technique [0002] The anti-wave plate is an important part that affects the line shape of the hull. When the ship is moving, its function is to guide the flow. Therefore, the line shape of the wave-proof plate must match the line shape of the entire hull. If the quality of its installation is defective, the line shape does not match the line shape of the hull, which will inevitably lead to changes in the flow field, resulting in negative effects. Because it has a linkage relationship with the front cover of the device. When the front cover of the equipment is opened, the anti-wave plate must also be opened; when the front cover of the equipment is closed, the anti-wave plate is closed, and the line shape of the anti-wave plate is consistent with that of the hull. Due to these two restricti...

AI Technical Summary

Problems solved by technology

Due to the distance between the front cover of the equipment and the hull surface, it is very difficult to draw lines with conventional slip needles; due to certain errors between the lofted model and the actual line shape, and the bonding between the model and the hull during the worker's operation and drawing The error, so the cumulative error cannot be estimated, in view of the accuracy of the anti-wave board
