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.
