Novel dieless test device and method for curved surface ship plate forming

Abstract

The invention discloses a novel dieless test device and a method for curved surface ship plate forming. The device comprises a frame mechanism and a measurement mechanism, wherein the frame mechanism comprises cross bars and longitudinal slipways mutually connected into a frame structure through thread; three cross supports are fixedly arranged between the longitudinal slipways equidistantly; each cross support is fixedly provided with a pull rope displacement sensor and a guide roller structure; the measurement mechanism comprises magnetic measurement heads and fixed length lines; the upper end of each fixed length line is connected with a connection buckle at the measurement head end; a connection buckle at a sensor end is in matched connection with the connection buckle at the measurement head end and quick assembly and disassembly are realized; and the magnetic measurement heads are provided with channels in two mutually-vertical diameter directions. The structure is simple, disassembly and movement can be carried out randomly, the mounting is convenient, and repeated use is realized; and in addition, through digital analysis by the software, the hull plate forming precision condition can be quickly measured and analyzed, and subjective test errors brought by manual measurement can be avoided.

Description

technical field [0001] The invention relates to the field of curved plate forming inspection, in particular to a novel moldless inspection device and method for curved ship plate forming. Background technique [0002] Most of the hull plate components are curved surfaces, and the manufacture of curved surface ship plate parts is an important link in shipbuilding production. The ship's three-dimensional numerical control plate bending machine is an important mechanical processing device for the cold-formation of the three-dimensional curved surface of the hull. For the inspection methods and devices after forming and processing of various curved ship plates, including three-dimensional numerical control plate bending machines for ships, at present, it mainly relies on wooden (iron) samples (boxes) or flexible samples for manual sample checking operations. The wooden (iron) sample (box) is an inspection tool that is manually made by workers based on the existing rib profile a...
