A kind of shape-calibrating tooling and shape-calibrating and glue-pouring method of annular thin-walled parts

Abstract

The invention discloses a ring-shaped thin-walled part shape correction tool and a shape correction and glue filling method, which belong to the technical field of parts glue filling. The cover plates are respectively detachably arranged at both ends of the positioning seat, the base and the positioning seat are in the shape of a rotating body, the positioning cover is in the shape of an annular plate, the base, the positioning seat and the positioning cover are arranged concentrically, the base and the positioning seat The bottom end is provided with an outwardly protruding outer edge, the positioning cover plate and the side surface of the positioning seat and the outer edge of the positioning seat form the inner ring shape correction groove of the part, and the outer edge of the base and the side surface of the base form the outer ring of the part Positioning groove, the shape correction and glue filling method of the annular thin-walled parts includes pre-shape correction, glue vacuum defoaming, glue filling and curing, and shaping steps. The shape correction tooling and processing method can fully guarantee the size of the glue filling parts , shape and internal quality of the colloid, so as to obtain high-quality glue filling products.

Description

technical field [0001] The invention relates to the technical field of glue filling of parts, in particular to a shape-calibrating tool of an annular thin-walled part and a shape-calibrating and glue-filling method. Background technique [0002] Room temperature vulcanized silicone rubber is a silicone rubber modified by adding hollow glass microspheres. Compared with ordinary silicone rubber, the modified silicone rubber has reduced elasticity, better mechanical properties, and better processability. Fine machining needs. At present, room temperature vulcanized silicone rubber is mainly used in the supercharged stator components of military and civilian high-pass ratio aero-engines. After the perfused colloid is cured, the stator blades are glued to the leaf-shaped holes of the inner ring of the stator to form the inner ring sealing surface. It plays the role of fixing and damping the stator blades. At the same time, after the colloid is vulcanized, it can be machined to a...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of tooling for correcting the shape of annular thin-walled parts and a method for correcting the shape and pouring glue. Correct the shape of the parts while filling the glue, solve the problem of difficult shape correction of thin-walled ring parts before glue filling, and facilitate demoulding. Bubble problem and the problem of difficult cleaning of glue filling equipment, high-quality glue filling products can be obtained through the shape correction tooling, shape correction and glue filling method
