Composite additive, accumulative and subtractive processing device with multi-robot cooperation, and process method

Abstract

The invention relates to a composite additive, accumulative and subtractive processing device with multi-robot cooperation, and a process method. The composite processing device comprises three independent industrial robots carrying end effectors with different functions, a robot position changer with two and more degrees of freedoms, and a working table. The manufacturing process comprises the steps of modeling a part to be processed to form three-dimensional data, and generating a standard template library (STL) file required for generating a slice layer under the programmed control; adopting an electric arc produced by a welding machine as a heat source, and through adding welding wires, gradually forming a metal part through line-surface-volume according to a three-dimensional digitalmodel. Through regulating the welding process parameters, different heights and spreading thicknesses of a component section are formed. The composite additive, accumulative and subtractive processingdevice with multi-robot cooperation provided by the invention is compact in structure, wide in processing range and high in product flexibility, has the advantages of high deposition efficiency, highmaterial utilization rate, short integrated manufacturing period, low cost, less limitation on part dimension, easiness in repairing the part and the like, has the capability on in-situ composite manufacturing and forming a large-size part, and achieves the aim of integrally net-shape forming the part.

Description

technical field [0001] The invention relates to a multi-robot cooperative multi-robot increasing and subtracting composite processing device and a process method, which are used for direct deposition and manufacturing of fine and complex metal structural parts, and belong to the field of cold and hot processing composite manufacturing of mechanical manufacturing. The invention utilizes a plurality of robots to operate cooperatively to complete processing processes such as additive forming, equal material control, and subtractive forming smoothing and repairing of metal parts, and provides a device and a process method. Background technique [0002] With the continuous implementation of resource-saving and efficient manufacturing-related technologies, for the manufacture of fine and complex metal parts, especially large structural parts such as aviation and ships, the additive manufacturing processing mode based on "addition" is constantly praised, which is different from the ...
