When the inner and outer fan-shaped bushings are oppositely installed, the fan-shaped end surfaces and the axial cylindrical surfaces are required to be attached to corresponding glue joint surfaces of frame beams of the machine body, relative movement does not occur in the glue joint curing process, and the distance tolerance between the fan-shaped end surfaces of the two bushings is 0.1mm. Because the space where the bushing is installed is narrow (the width is 8mm, and the maximum diameter is 74mm of the fan-shaped groove), if vacuum bag pressing is adopted, the risk of dislocation in the bushing curing process exists, and the distance between the end faces of the bushing is difficult to measure due to the existence of soft materials such as the vacuum bag and the ventilated felt after vacuum pumping. It is difficult to ensure the distance between the fan-shaped end faces of the two bushings.
