AI Technical Summary
The existing process of installing beveled bushings can easily lead to bushing failure, requires high worker skills, has a long assembly time, high labor intensity, and makes it difficult to ensure the alignment and concentricity of the bushing and the lower torque arm.
The system employs a support, bushing positioning assembly, bushing guide, and press-in mechanism. The bushing is cooled by liquid nitrogen, and the bushing orientation is fixed by a stop. Combined with the press-in mechanism and magnetic material positioning, it ensures that the bushing is firmly locked after thermal expansion and contraction to room temperature dimensions.
It improved assembly quality and work efficiency, reduced the scrap of parts, lowered the skill requirements for operators, and simplified the installation process.
