Honing Tool Sliding Skids Centering Cylindrical Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing honing tools for cylindrical external surfaces of rods, such as aircraft landing gear rods, risk damaging the surfaces due to vibratory phenomena during the honing process, leading to potential oxidation points and fatigue crack starter points.
Innovation Solution
A honing tool with sliding skids and honing inserts that simultaneously contact the cylindrical surface to center and stabilize the rod, reducing vibratory issues and enhancing uniform honing by minimizing friction from the skids and maximizing friction from the honing inserts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional honing tools with only honing inserts are used, then the honing process can be performed, but vibratory phenomena occur causing surface damage and geometric defects
Solution Approach 1:
Sliding skids are introduced as intermediary elements between the honing inserts and the cylindrical surface. These skids serve as mediators that stabilize the positioning of the honing inserts, reduce clearance variations, and suppress vibratory phenomena during the honing process, thereby improving surface quality without compromising the honing function
Solution Approach 2:
The sliding skids make preliminary contact with the cylindrical surface before the honing inserts engage. This preliminary action centers and stabilizes the workpiece, ensuring proper positioning and minimizing clearance variations before the actual honing operation begins, thus preventing vibratory phenomena
2Object-affected harmful factors
If honing inserts are positioned close to the cylindrical surface to reduce clearance, then vibratory phenomena are reduced, but the risk of damaging the surface during positioning increases
Solution Approach 1:
The sliding skids act as intermediary elements that enable the honing inserts to be positioned close to the cylindrical surface for vibration reduction while preventing direct damaging contact. The skids guide and center the workpiece, allowing the inserts to engage at optimal clearance without causing surface damage during positioning
Solution Approach 2:
The sliding skids perform preliminary centering and stabilization of the workpiece before the honing inserts engage the surface. This preliminary positioning action ensures that when the inserts contact the surface at minimal clearance, it is done in a controlled manner that reduces vibrations without causing damage
3Manufacturing precision
If sliding skids are added to the honing tool, then positioning accuracy and vibration reduction are improved, but device complexity increases
Solution Approach 1:
The honing tool is segmented into distinct functional components: sliding skids for centering and stabilization, and honing inserts for surface finishing. This segmentation allows each component to perform its specific function optimally while maintaining modularity and relatively simple individual structures, balancing positioning accuracy with device complexity
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
The tool effectively limits vibratory phenomena and geometrical defects, ensuring precise and uniform honing of the cylindrical external surface, thereby improving the surface quality and reducing the risk of damage.
Implementation Method 1
The sliding skids and the honing inserts are arranged to be capable of coming simultaneously into contact against the cylindrical external surface of the rod... so as to be able to center the cylindrical external surface inside said passage. The sliding skids limit the amplitudes of movement between the honing inserts and the cylindrical surface, including during rotation of the insert support around the rod.
Implementation Method 2
a plurality of honing inserts adapted to hone a metal... the inserts being carried by the support so as to define a passage around which the inserts are to be found and in which it is possible to introduce the cylindrical external surface of the rod.
