Portable Press for In-Place Removal of Press-Fit Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical assemblies with press-fit components are inconvenient and time-consuming to disassemble for accessing and removing or inserting parts, necessitating a portable solution for minimal disassembly.
Innovation Solution
A portable press device with a force application member that slidably engages guides, utilizing a pneumatic or hydraulic actuator to apply force for pressing parts in or out of a housing, allowing for vertical or horizontal operation and easy movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a press is used to remove or install press-fit parts, then the parts can be properly assembled or disassembled, but the device requires extensive disassembly of the mechanical construct to access the press-fit part
Solution Approach 1:
A portable press device serves as an intermediary tool that can be positioned between the housing and the press-fit part (bearing, bushing, or kingpin) to apply direct force for removal or installation without requiring disassembly of the mechanical construct. The portable press acts as a mediator that enables access to confined spaces where traditional fixed presses cannot reach.
2Force
If a traditional fixed press is used, then sufficient force can be applied for press-fitting, but the press cannot be moved to the mechanical structure requiring service
Solution Approach 1:
The press device transitions from a fixed, stationary configuration to a portable, movable configuration. The press incorporates movable components including a movable pressing surface that can be positioned at various locations, and the entire device can be relocated to different mechanical structures requiring service. This dynamic design maintains sufficient pressing force while enabling portability and adaptability to different work locations.
3Productivity
If the mechanical construct is disassembled to access press-fit parts, then the parts can be removed or installed, but the process becomes time-consuming
Solution Approach 1:
The portable press device is prepared and positioned in advance at the location of the press-fit part before the actual pressing operation begins. The device can be pre-configured with the appropriate pressing force and positioning, allowing immediate execution of the removal or installation operation without time-consuming setup or disassembly procedures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient removal and installation of press-fit parts with minimal disassembly, facilitating access to components like bearings, bushings, and kingpins in mechanical devices without requiring extensive disassembly.
Implementation Method 1
An actuator, such as a pneumatic or hydraulic jack or cylinder, applies force to the force application member to advance the force application member toward the static plate
Data Source
AI summary
A portable press is usable with parts that are assembled by interference fit or friction fit. A force application member slidably engages a plurality of guides. An actuator, such as a pneumatic or hydraulic jack or cylinder, applies force to the force application member to move the force application member toward a static plate. The force application member acts to either press in, or press out, a first part relative to a second part. The press of the invention is portable, so that the press can be moved to the mechanical structure requiring a press for removal or insertion of parts. The press may be constructed in a vertical or horizontal embodiment.
