Abstract

The invention discloses a positioning device for stator assembly welding. According to the positioning device, a stator assembly is supported through a base, an outer ring is positioned on the base through an outer ring positioning structure, an inner ring is positioned on the base through an inner ring positioning structure, then positioning of a blade is completed through insertion contact between a positioning unit and the blade, so that the blade has the only determined position in the stator assembly, it is guaranteed that the position degree, the uniform distribution degree and the swing angle of the blade after spot welding meet the assembly requirements, after spot welding of one single blade is completed, the positioning unit is driven by a rotating unit to rotate so as to complete positioning and welding of a plurality of blades one by one, and therefore repeated disassembly and assembly of the positioning device are avoided. According to the scheme of the positioning device, the outer ring, the inner ring and the blades are fixed and positioned in a targeted mode respectively through the base, the outer ring positioning structure and the inner ring positioning structure according to the structural shapes and working characteristics of the outer ring, the inner ring and the blades, so that it is guaranteed that all parts of the stator assembly are accurately and rapidly positioned, and the effect that the part machining efficiency is high while the part machining quality is good can be achieved.

Description

technical field [0001] The invention relates to the technical field of aero-engines, in particular to a positioning device for welding a stator assembly. In addition, the present invention also relates to a positioning method for stator assembly welding using the above positioning device for stator assembly welding. Background technique [0002] An existing stator assembly of a turboprop engine consists of three parts: an outer ring, an inner ring, and blades (multiple). Among them, the outer ring and the blade are connected by vacuum brazing, and the inner ring and the blade are connected by silicone rubber embedding. Positioning spot welding is required before brazing of the outer ring and the blade (each blade has multiple positioning welding points). However, due to the thin size of the outer ring and the inner ring and the large airfoil hole, the blade will swing in the airfoil hole after being installed between the inner and outer rings, and the position of the blade...
