Problems solved by technology

Moreover, these pipes and cylinders usually have a certain spatial angle with the base of the hull. If they run through the hull plating, especially in the bow and stern areas, since the hull plating is an irregular and complex surface, it is difficult to open holes, draw The difficulty of the line is greatly increased, and multiple operations are required. Not only the quality of the line marking is poor, the accuracy is low, but also a lot of manpower and material resources are consumed, and the construction efficiency is low.

Abstract

The invention relates to the technical field of ship construction, in particular to a curved surface circular hole scribing and punching device and method. According to the curved surface circular hole scribing and punching device, a complex curved surface barrel of a ship body is subjected to punching for scribing, so that a conventional plastic paper sample can be replaced. In a process of scribing or punching, a transverse circular rod can move freely along a center shaft, so that perfect jointing of an operation tool with a punching surface is realized. The device and the method are particularly suitable for scribing and punching of the complex curved surface of the ship body in the presence of a spatial angle or a punched hole between the barrel and the ship body; the scribing and punching accuracies can be increased greatly, convenience is brought to use, and the construction efficiency is increased; the punching device fixed through a lower hinge magnet and a fixing magnet, so that the connection is firm; moreover, convenience is brought to assembly and disassembly, and the construction efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a device and method for scribing and opening round holes on a curved surface. Background technique [0002] In the process of ship construction, there are a large number of cylindrical outfitting parts, equipment pipes, and equipment cylinders, such as side thrust pipes, full-turn rudder cylinders, crane cylinders, anchor chain pipes, anchor platforms, and anchor holes. When installing, it needs to penetrate through the hull structure or be attached to the outer plate of the hull. Before installation, it is necessary to make holes in the penetrated structure or mark the installation position. Because these outfitting, equipment pipes, and equipment cylinders have high requirements for installation accuracy, that is, there are strict requirements for the clearance between the outfitting and equipment and the hull structure after installation. Moreover, these pipes and cylin...
