A method and device for maintaining the verticality of the musket head for complex outer plate processing of the hull

Abstract

The embodiment of the invention discloses a method and device for maintaining the perpendicularity of a line heating machine head for machining a complex ship hull plate, and the method and device are used for solving the technical problem that the perpendicularity between a line heating machine and the machined hull plate is hard to maintain. The method comprises the steps that working point coordinates are extracted from obtained point cloud data of the machined hull plate; at least three anchor points which are located on the machined hull plate and keep a fixed distance from a working point are discovered through scanning with the working point coordinates serving as the center; target normal vectors of the machined hull plate on the working point coordinates are calculated according to the anchor points; a space azimuth angle in the RX direction and a space azimuth angle in the RZ direction are calculated according to the target normal vectors; and the line heating machine is controlled to rotate in the RX direction according to the space azimuth angle in the RX direction, and the line heating machine is controlled to rotate in the RZ direction according to the space azimuth angle in the RZ direction.

Description

technical field [0001] The invention relates to the field of automatic processing of complex outer plates of ship hulls, in particular to a method and device for maintaining the verticality of musket heads for processing complex outer plates of ship hulls. Background technique [0002] The complex outer plate of the hull, also known as water-fire bending plate, uses the property of metal deformation when heated, heats the metal panel at high temperature to deform it, and then adds water to cool it to form an overall bending process. [0003] In the current water and fire bending process, manual operation is generally used, and the degree of automation is relatively low. Moreover, this method is time-consuming and laborious. Workers with 2-3 years of processing experience are required to grasp the degree of heating deformation. [0004] When automatic processing of water and fire bent plates is used, the heating gun often deforms too much due to the heating of the processed b...
