Plugging device and method for powder clearing hole of selective laser melting forming wing rudder structure

Abstract

The invention relates to a selective laser melting forming wing rudder structure powder clearing hole plugging device and method. The selective laser melting forming wing rudder structure powder clearing hole plugging device comprises a plugging support, a plugging device, a position recognition and feedback module, a quality detection module, a control terminal and a transmission module. Wherein the plugging support serves as a bearing structure of the plugging device, the position recognition and feedback module and the quality detection module, and the control terminal is connected with the plugging device, the position recognition and feedback module, the quality detection module and the transmission module and controls the plugging process. According to the technical scheme, high-quality and automatic high-efficiency plugging of the powder cleaning hole of the wing rudder structure can be achieved; the rapid quality detection of the plugging position can be realized; and the requirement for blocking batch powder clearing holes generated by batch production of selective laser wing rudder structures can be met, so that the automation level of the whole additive manufacturing process is improved.

Description

technical field [0001] The invention relates to the field of post-processing of additive manufacturing, in particular to a device and method for plugging a powder cleaning hole of a wing rudder structure formed by laser selective melting. Background technique [0002] Selective laser melting forming technology uses focused laser light source to selectively irradiate the pre-spread metal powder to form three-dimensional metal parts layer by layer. Compared with the traditional casting and forging technology, laser selective melting forming technology can obtain rapidly solidified non-equilibrium structure, fine internal grains, excellent comprehensive mechanical properties, and can form parts with arbitrary structures and many other advantages. Design and manufacturing provide new ideas and become an important development direction of advanced manufacturing in the aerospace field. [0003] The closed-cavity wing rudder integrated manufacturing is realized by using laser sele...
