AI Technical Summary

Technical Problem

The existing technology for installing and removing inner hole bushings of parts is inefficient and can easily lead to bushing misalignment or damage to the parts, making it unsuitable for mass production.

Method used

An installation and disassembly device is designed, comprising a slide rail, a slider, a housing, a fixed support, a limit screw, a positioning shaft support, a sliding positioning shaft, a fixed shaft, a reset spring, a movable base, a movable support, an adjustable support, a handle, and an anti-detachment mechanism. This device enables the rapid installation and disassembly of the bushing through uniform force application.

Benefits of technology

This enables rapid and uniform installation and removal of bushings, avoiding misalignment and damage to parts, and improving assembly quality and efficiency.
