Abstract

The invention discloses a measuring system and measuring method in a machining process of a ship curved plate. The measuring system comprises an optical measuring device, a portal device, a moving apparatus and a power supply and control apparatus, wherein the optical measuring device comprises a linear laser three-dimensional measuring apparatus for measuring a width direction of the curved plateand a crossing laser three-dimensional measuring apparatus for measuring a length direction of the curved plate, the portal apparatus comprises a pressing bent portal and a rolling bent portal, the linear laser three-dimensional measuring apparatus is arranged on the pressing bent portal, the crossing laser three-dimensional measuring apparatus is arranged on the rolling bent portal, the moving apparatus comprises a left traveling crane and a right traveling crane and is used for adjusting the position of the ship curved plate, and the power supply and control apparatus is used for powering and controlling the optical measuring device, the portal apparatus and the moving apparatus. The measuring system and measuring method in the machining process of the ship curved plate is mainly used for measurement during the machining of the ship curved plate; and by adopting the novel measuring system and method, measuring errors are reduced, and the production efficiency and production qualitycan be improved.

Description

technical field [0001] The invention relates to the technical field of measurement in the shipbuilding process, in particular to a measurement system and a measurement method for the processing of ship curved plates. Background technique [0002] The traditional ship curved plate processing is mainly carried out by the combination of hydraulic press and water and fire bending. During the processing process, the operator needs to hold a wooden model or sample box to carry out continuous manual visual inspection and inspection of the shape of the processed curved plate. Usually, processing a ship curved plate requires 4-5 experienced operators cooperate with each other to complete, such as Figure 6 As shown, the wooden sample is used to measure the processing degree of the ship’s curved plate, and its shape and curvature are consistent with the processed curved plate. By manually judging the degree of agreement between the wooden sample and the ship’s curved plate, the process...

Problems solved by technology

[0003] Some people in China have conducted research on the processing of ship curved plates or the measurement of the processing process and achieved certain results, but most of them are still in the ideal state and small-scale measurement stage, and have not completely solved the pain points of the actual shipyard curved plate processing process. It mainly has the following problems: (1) It is mainly suitable for one-time molding of ship curved panels with a square meter of 3 meters and a thickness of less than 20 mm; (2) The mechanical structure is complex and the failure rate is high; (3) The material requirements for curved panels Higher, cannot cover the production and manufacturing of ordinary ships
