Abrasive Strip Holder With Forming Tunnel for Precision Deburring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deburring processes for precision workpieces, such as multipoles in mass spectrometers, are manual and time-consuming, leading to inconsistent quality and potential damage to precision surfaces due to the lack of suitable automated deburring machines and tools.
Innovation Solution
A deburring tool with a belt holder that enables automatic renewal of the grinding belt, featuring a forming tunnel with a tubular and funnel-shaped section to facilitate belt insertion and folding, allowing for automated belt replacement and consistent quality, and a pneumatic or electromagnetic drive for alternating stroke motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual deburring is used, then quality control is simple, but productivity is low and time is consumed
Solution Approach 1:
The forming tunnel is designed to automatically fold the grinding belt in the longitudinal direction as it passes through, eliminating the need for manual belt preparation and folding. The belt holder automatically positions and secures the belt, enabling autonomous operation that increases productivity while maintaining consistent quality.
Solution Approach 2:
The forming tunnel pre-folds the grinding belt in the longitudinal direction before it reaches the working area. This preliminary folding action ensures the belt is properly configured for automated deburring operations, eliminating manual preparation steps and improving productivity.
2Manufacturing precision
If a transverse abrasive belt insertion is used, then the tool can be simple, but machining precision deteriorates due to rotating free ends
Solution Approach 1:
The forming tunnel pre-folds the grinding belt in the longitudinal direction before it reaches the working area. This preliminary folding action ensures the belt is properly configured for automated deburring operations, eliminating manual preparation steps and improving productivity.
Solution Approach 2:
The forming tunnel is designed to automatically fold the grinding belt in the longitudinal direction as it passes through, eliminating the need for manual belt preparation and folding. The belt holder automatically positions and secures the belt, enabling autonomous operation that increases productivity while maintaining consistent quality.
3Manufacturing precision
If the grinding belt is replaced for each workpiece, then quality consistency is improved, but productivity decreases due to frequent replacements
Solution Approach 1:
The forming tunnel continuously folds the grinding belt in the longitudinal direction as it passes through, enabling continuous operation without interruption. This continuous folding action ensures consistent belt configuration for each workpiece, maintaining quality uniformity while improving productivity by eliminating stop-time for belt preparation.
