Abstract
The invention relates to a weld assembly correction method. The weld assembly correction method comprises the following steps that step A, a bottom plate is provided, wherein an outer centering ring,an inner centering ring and a mandrel are coaxially arranged on the bottom plate from outside to inside, a bushing connected through a flat key is installed on the mandrel, and then an included anglebetween an annular cover plate and a vertical plane of a central axis is measured by using a measuring rod rotatably connected with the bushing, so that the direction to be corrected is judged; and step B, according to the direction to be corrected determined in the step A, the measuring rod and the bushing are taken down, and a weld assembly is corrected. According to the weld assembly correctionmethod, it is ensured that the positioning reference is always constrained in the correction process, so that the influence of top correction on the bottom reference is avoided, and the uniformity ofthe reference is ensured. The invention further provides a device applied to the method.
Description
technical field [0001] The invention relates to the technical field of post-welding fitters, in particular to a method for correcting welded parts used in aero-engines and a used device. Background technique [0002] figure 1 It is a schematic diagram of the cross-sectional structure of an aero-engine welded part, such as figure 1 As shown, the welding part 1 is a weldment, which can be used as a flame tube part of an aero-engine. It is an annular part, which is welded by a coaxial stepped inner ring 11, a stepped outer ring 12 and an annular cover plate 13. The annular cover plate 13 is provided with a plurality of through holes 131, the bottom of the stepped inner ring 11 is provided with an inward convex edge 111, the inner side wall of the convex edge 111 is parallel to the axis, and the bottom surface is perpendicular to the axis, so The bottom surface of the stepped outer ring 12 is perpendicular to the axis, the bottom of the stepped outer ring 12 is provided with a...
