Deburring Tool Pusher Structure for Distal-End Spring Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deburring tools require disassembly for replacing the elastic body, which complicates the process and increases user effort due to the need to replace the elastic body based on workpiece material and chamfer width.
Innovation Solution
A processing tool with a detachable pusher mechanism that allows for easy replacement of the advance-retract spring from the distal end, featuring a cylinder chamber, slide groove, anti-rotation groove, and a simple structure for tool attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the elastic body is replaced from the distal end, then the replacement process is simplified and user effort is reduced, but the structure becomes more complex requiring additional components like the openable elastic body and retaining body with lever
Solution Approach 1:
The pusher is divided into separable components: the pusher body, the retaining body with lever, and the openable elastic body. This segmentation allows the elastic body to be replaced independently from the distal end through the lever mechanism, while the main body structure remains intact. The segmentation enables simplified replacement operation without requiring full disassembly.
2Ease of repair
If the pusher is made detachably attachable for easy maintenance, then the ease of repair is improved, but the reliability of the connection may deteriorate
Solution Approach 1:
The retaining body with lever is extracted as a separate functional unit that can be removed from the pusher body. This extraction allows the pusher to be easily detached and replaced for maintenance, while the lever mechanism ensures secure attachment when assembled. The design separates the attachment function from the pusher body, enabling easy repair without compromising connection reliability through the dedicated retaining structure.
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 quick and easy replacement of the pusher mechanism without disassembling the tool, improving user convenience and efficiency in adjusting the pressing force for different workpiece materials and chamfer widths.
Implementation Method 1
an openable elastic body configured to urge the retaining body radially outward
Implementation Method 2
an advance-retract spring disposed on a basal end of the pusher in the cylinder chamber, the advance-retract spring configured to urge the pusher toward the distal end

AI summary
A processing tool includes: a body including a cylinder chamber having an opening toward a distal end, and a slide groove extending parallel to the cylinder chamber; a tool received in the cylinder chamber in a detachably attachable manner, and having an anti-rotation groove on an outer periphery; an anti-rotation body disposed in the body and advance to or retract from the cylinder chamber; a pusher disposed in the cylinder chamber in a reciprocable manner, and urges the tool toward the distal end, the pusher including, a pusher body, a retaining body received in the slide groove, and an advance-retract spring disposed on a basal end of the pusher in the cylinder chamber, and urge the pusher toward the distal end.
