Laser processing device for special-shaped light and thin flexible titanium alloy part for aero-engine

Abstract

The invention provides a laser processing device for a special-shaped light and thin flexible titanium alloy part for an aero-engine, which comprises a laser cutting platform guide rail, and is characterized in that the device further comprises at least two stand column assemblies and at least one supporting rod assembly; a universal device is assembled at the top end of a stand column of each stand column assembly; guide grooves are formed in the roots of the stand columns and move in cooperation with the guide rail; clamping grooves of universal heads of the universal devices are used for clamping a special-shaped titanium alloy sheet metal workpiece; a guide groove is formed in the root of a supporting cylinder of the supporting rod assembly and moves in cooperation with the guide rail; and a clamping groove is formed in the top end of a supporting screw of the supporting rod assembly and used for clamping and supporting the special-shaped titanium alloy sheet metal workpiece for machining. Accurate and efficient laser machining of special-shaped light and thin titanium alloy sheet metal materials is achieved, light and thin titanium alloy sheet metal workpieces of various sizes and complex special shapes can be assembled and fixed, the manual operation difficulty and workload are simplified, and the machining cost is remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of titanium material processing, and relates to laser cutting technology, in particular to a special laser processing device for processing special-shaped light, thin and flexible titanium alloy sheet metal materials for aero-engines. Background technique [0002] In recent years, laser plane cutting processing platforms have been widely used. Laser plane cutting processing platforms can efficiently and economically cut materials from thin to medium thickness, but stainless steel, aluminum metal materials and low carbon steel plates are mostly processed, and widely used Used in automobiles, shipbuilding, electric power, petroleum, and chemical machinery, it satisfies the cutting and processing requirements of these planar sheet metal parts. [0003] According to the existing public information, in the aviation field, there is a layer of skin on the outside of the aircraft fuselage, aircraft wing, and engine ...

AI Technical Summary

Problems solved by technology

[0004] It can be seen from this that the aircraft skin has the characteristics of lightness and flexibility, and its processing has high precision and special quality requirements. Especially with the technical needs of supersonic, hypersonic and large-scale aircraft, some aircraft skins The space structure is irregular, the structure is complex, the force is complex, it has the characteristics of high precision and difficult processing, which will inevitably increase the difficulty of processing the already difficult-to-process titanium alloy material plate, and pose a challenge to the existing processing technology

Therefore, some special-shaped and thin aviation titanium alloy sheet metal parts have technical defects that are difficult to process or have low processing accuracy. The existing processing technology cannot meet the quality requirements of modern aviation special-shaped sheet metal parts.
