Wire additive and reductive combination machining equipment and application thereof

Abstract

The invention discloses wire additive and reductive combination machining equipment. The wire additive and reductive combination machining equipment comprises an on-line metal arc welding wire additive manufacture device and a numerical control multi-axis linkage machining device, wherein the on-line metal arc welding wire additive manufacture device comprises a welding robot and a welder system; the welder system is arranged on the welding robot; the multi-axis linkage machining system comprises a three-dimensional measurement device and a multi-axis linkage precise machining system; the three-dimensional measurement device is used for measuring the outline information of a part and transmits the information to a computer; the computer is used for obtaining the real outline of the part through the received outline information, then compares the real outline with a theoretical three-dimensional model to obtain an error; and the multi-axis linkage precise machining system is used for performing wire reductive machining on the part, so that the error between the real outline and the theoretical three-dimensional model is controlled in a preset range. By adopting the wire additive and reductive combination machining equipment, the problem of a current precise machining method that a part with a complex shape can hardly be machined automatically is solved; and the advantages of arc welding wire additive manufacture of high efficiency, low energy consumption and high environment adaptability can be fully exerted.

Description
