Embodiment 1

[0044] refer to figure 1 , an annular thin-walled part shape correction tool, comprising: a base 1, a positioning seat 2 and a positioning cover 3, the base 1 and the positioning cover 3 are respectively detachably arranged at both ends of the positioning seat 2, the base 1 and the positioning seat 2 is a cylindrical structure of a rotating body, and the positioning cover plate 3 is an annular plate-shaped structure, refer to figure 2 The bottom surface of the positioning cover plate 3 is provided with a first positioning female notch 31, the base 1, the positioning seat 2 and the positioning cover plate 3 are concentrically arranged, and the bottom ends of the base 1 and the positioning seat 2 are provided with outwardly protruding outer edges, refer to figure 2 , the outer edge of the positioning seat 2 is provided with a second positioning female notch 21, refer to figure 1, the outer edge of the base 1 is provided with a third positioning female notch 11, the positioni...

Embodiment 2

[0061] The difference between this embodiment and Embodiment 1 is that in step c of the glue liquid vacuum defoaming of the annular thin-walled part shape correction and glue pouring method, the vacuum defoaming pressure is 4.5KPa, the vacuum defoaming time is 20min, and the degassing 3 times; in step e curing and shaping, place the parts filled with glue at room temperature for 14 hours, and then heat and cure. The curing temperature is 100°C and the curing time is 1.3 hours.

Embodiment 3

[0063] The difference between this embodiment and Embodiment 1 and Embodiment 2 is that in step c of the glue solution vacuum defoaming in the shape correction of the annular thin-walled parts and the glue pouring method, the vacuum defoaming pressure is 4KPa, and the vacuum defoaming time is 25min , degassing 4 times; in step e curing and shaping, place the filled parts at room temperature for 15 hours, and then heat and cure. The curing temperature is 105°C and the curing time is 1 hour.

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...
