Angle Grinder Adaptor With Blade Support for Uniform Mower Sharpening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintaining a proper 30° to 40° cutting edge and consistent grinding depth during mower blade sharpening with angle grinders is challenging due to variations in grinding angle and depth, leading to uneven cutting edges.
Innovation Solution
A mower blade sharpening angle grinder adaptor with a durable steel 'U' bracket, table, and annular clamp that securely attaches to the grinder, providing a guided support for the blade at a consistent angle and depth, ensuring uniform grinding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If angle grinder is used for grinding mower blade, then grinding operation can be performed, but maintaining proper 30° to 40° cutting edge angle becomes difficult
Solution Approach 1:
The patent introduces a blade support table as an intermediary component between the mower blade and the grinding wheel. This table is positioned at a precise angle relative to the grinding wheel and provides a reference surface that guides the blade at the correct 30° to 40° bevel angle during grinding, eliminating the difficulty of maintaining proper angle without requiring complex positioning techniques
2Ease of operation
If angle grinder is used for grinding mower blade, then grinding operation can be performed, but consistent grinding depth cannot be maintained
Solution Approach 1:
The blade support table serves as a mediator that establishes a consistent reference plane for the blade during grinding. By positioning the table at a fixed distance and angle relative to the grinding wheel, it ensures uniform grinding depth across the entire blade length, eliminating variations in grinding pressure and contact point that would otherwise occur
3Productivity
If angle grinder is used for grinding mower blade, then grinding operation can be performed, but uneven cutting edge is produced
Solution Approach 1:
The blade support table acts as a mediator that ensures uniform contact between the blade and grinding wheel throughout the grinding process. By providing a stable angular reference and consistent positioning, it prevents the blade from shifting or tilting during grinding, thereby producing an even cutting edge while maintaining efficient grinding operation
