Pivoting Roller Burnishing Tool for Precise Radial Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller burnishing tools face challenges in achieving fine adjustments due to the radial displacement of the roller holder along a straight line, which results in significant resistance and weakening of the base body, making precise adjustments difficult.
Innovation Solution
The roller burnishing tool incorporates a pivotable holder arm that allows radial adjustment of the rolling cylinder by pivoting, reducing the need for a large recess in the base body and minimizing contact surfaces, thereby enabling a stable and precise adjustment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the roller holder is radially displaced along a straight line in a rectangular recess, then the roller holder can be adjusted radially, but the base body is considerably weakened and the roller holder experiences significant resistance to radial displacement
Solution Approach 1:
The roller holder is divided into two functional parts: a holder body that is fixedly connected to the base body, and a holder arm that can be pivoted radially. This segmentation allows the adjustment function to be isolated to the holder arm, preserving the structural integrity of the base body while enabling precise radial adjustment of the rolling cylinder.
Solution Approach 2:
The holder arm is designed to be pivotable in the radial direction rather than requiring linear radial displacement of the entire roller holder. This dynamic pivoting motion reduces friction and resistance during adjustment, while the holder body remains firmly fixed to the base body, maintaining structural strength.
2Manufacturing precision
If the roller holder is radially displaced along a straight line, then the rolling cylinder position can be adjusted, but the roller holder experiences significant resistance making fine adjustment difficult
Solution Approach 1:
The holder arm is designed to pivot radially with minimal friction, enabling smooth and precise adjustment of the rolling cylinder position. The pivoting motion mechanism reduces resistance compared to linear displacement, allowing operators to achieve fine adjustments easily while the holder body remains firmly fixed.
Solution Approach 2:
The holder arm acts as an intermediary between the fixed holder body and the rolling cylinder. By pivoting the holder arm, the rolling cylinder position can be precisely adjusted without moving the entire roller holder, reducing resistance and improving adjustment ease.
3Adaptability or versatility
If a large recess is created in the base body to accommodate the roller holder, then the roller holder can be adjusted radially, but the base body structure is weakened
Solution Approach 1:
The roller holder is segmented into a holder body that is minimally connected to the base body and a holder arm that provides the adjustment function. This segmentation allows radial adjustability of the rolling cylinder while requiring only a small recess in the base body, preserving structural stability.
Solution Approach 2:
The radial adjustment function is extracted from the base body structure and assigned to the pivoting holder arm. This extraction allows the base body to maintain its structural integrity with minimal recess, while the holder arm provides the necessary adaptability for radial adjustment of the rolling cylinder.
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
This design allows for a more stable and precise adjustment of the roller holder, maintaining constant contact pressure and alignment, even during radial displacement, enhancing the tool's ability to create defined surface structures on cylindrical workpieces.
Implementation Method 1
the roller burnishing tool is rolled on the workpiece surface to be processed with a prescribed contact pressure, as a result of which the workpiece surface to be processed undergoes plastic deformation
Implementation Method 2
The control slant of the control device together with the abutting slanted surface of the roller holder form a wedge gear, which converts an axial displacement of the adjusting rod into a radial displacement of the roller holder
