Bushing Assembly Displacement Tool for Precise Insertion and Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for inserting and removing bushing assemblies, particularly those with bushing pins and elastomeric material, are inefficient and lack effective tools for precise positioning and displacement within structural members.
Innovation Solution
A bushing assembly displacing system comprising a drive system with an actuator, threaded rod, and brace nut, along with a pullbar socket and push adapter, is used to connect to the bushing rod and sleeve, and a receiver assembly with a cylinder adapter and extension tube, allowing for precise displacement and positioning of bushing assemblies relative to a housing opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional pressing methods are used to insert bushings into housing openings, then the bushing can be installed, but the process is inefficient and lacks precise positioning control
Solution Approach 1:
The patent introduces a specialized pressing tool system that acts as an intermediary between the pressing force source and the bushing assembly. This tool includes positioning features that interface with the bushing and housing opening, providing controlled displacement and precise positioning during installation and removal operations
Solution Approach 2:
The pressing tool is designed to self-position within the housing opening using positioning features such as ribs that engage with corresponding features in the housing. This self-positioning capability eliminates the need for external alignment equipment and enables precise positioning automatically during the pressing operation
2Ease of operation
If manual removal methods are used for bushing assemblies, then removal is possible, but significant manual effort is required and the process is time-consuming
Solution Approach 1:
The pressing tool serves as a mechanical intermediary that translates actuator motion into controlled displacement of the bushing assembly. The tool's positioning features and engagement mechanisms with the bushing rod enable efficient removal with minimal manual effort by providing mechanical advantage and controlled force application
Solution Approach 2:
The pressing tool is designed with movable components that can be displaced along the bushing rod, allowing dynamic adjustment during the removal process. The actuator-driven mechanism provides controlled dynamic motion rather than static manual force application, significantly reducing the time and effort required for bushing removal
