Shape integration detection platform and method for local additive manufacturing process of super-large component

Abstract

The invention discloses a shape integration detection platform and method for a local additive manufacturing process of a super-large component. The platform comprises a component transposition machine, three industrial robots, and a laser ultrasonic detection device, a three-dimensional precision measuring instrument and a CMT welding gun which are clamped by the three robots, and the CMT weldinggun is used for material additive manufacturing on a component to be machined. The laser ultrasonic detection device is used for performing long-distance laser ultrasonic nondestructive detection onthe machined component; and the three-dimensional precision measuring instrument is used for monitoring the overall dimension and the shape of the component in material additive manufacturing in realtime. According to the invention, the component transposition machine is adopted for rotating the component to achieve the cycle switching among the three stations of material addition, laser ultrasonic detection and the three-dimensional shape detection and achieve shape integration detection of the component to be machined in the material additive manufacturing process. Defects can be found in time, then machining is performed to eliminate the defects, materials are saved, working hours are reduced, and the overall machining efficiency is improved.

Description

technical field [0001] The invention belongs to the field of component manufacturing, and relates to a super-large component composite manufacturing technology, and more specifically relates to a shape-property integrated detection platform and a detection method used in the local additive manufacturing process of super-large components. Background technique [0002] The main pipeline of nuclear power is mainly composed of a pipeline base and several nozzles. The traditional manufacturing method is that the substrate is formed by one-piece forging and pressing, and then the pre-processed nozzle parts are welded to the substrate by manual surfacing. This method makes it difficult to control the welding quality of the nozzle, and when a defect occurs, the entire nozzle needs to be processed and re-welded, resulting in waste of materials and man-hours. [0003] The composite manufacturing of the main pipeline of nuclear power incorporates the additive manufacturing technology....
