Processing Pad Groove Edges for Bevel Portion Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing apparatuses are inadequate in effectively processing the bevel portion of workpieces with a bevel portion at their outer circumferential edge.
Innovation Solution
A processing apparatus with a workpiece table and processing head, featuring a processing pad with inner and outer circumferential groove walls that rotate and swing to contact the bevel portion, allowing for effective processing by adjusting the contact range and orientation during the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional processing pad is used without grooves, then the structure is simple, but the bevel portion of the workpiece cannot be effectively processed
Solution Approach 1:
The processing pad is segmented by forming grooves that divide the pad surface into multiple functional regions. The grooves create inner and outer circumferential groove walls with edges that specifically contact the bevel portion, separating the bevel processing function from the flat surface processing function, thereby enabling effective bevel processing without complicating the entire pad structure
Solution Approach 2:
The grooves are strategically positioned and dimensioned so that the inner and outer circumferential groove walls with their edges provide localized contact with the bevel portion. This local structural feature concentrates the processing action on the bevel area, improving processing effectiveness without requiring the entire pad to be complex
2Manufacturing precision
If the processing pad contacts the workpiece with a flat surface, then the contact area is large, but the bevel portion cannot be effectively processed
Solution Approach 1:
The grooves extract material from the pad surface, creating three-dimensional groove walls with edges. These extracted edges are specifically designed to contact and process the bevel portion, separating the bevel processing function from the general flat surface contact, thereby enabling effective bevel processing without requiring the entire pad surface to be complex
3Manufacturing precision
If the processing apparatus does not include a swing mechanism, then the structure is simple, but the processing range and contact precision are limited
Solution Approach 1:
The swing mechanism introduces dynamic adjustability to the processing apparatus, allowing the processing pad to be swung between a first position for processing the flat surface and a second position for processing the bevel portion. This dynamic positioning enables precise contact with the bevel portion while maintaining overall apparatus simplicity through a single swingable component
4Adaptability or versatility
If the processing pad has a fixed contact position, then the structure is simple, but the processing range cannot be adjusted
Solution Approach 1:
The swing mechanism provides dynamic adjustability by allowing the processing pad to be positioned at different angles - a first position for flat surface processing and a second position for bevel processing. This single dynamic component enables adjustment of the processing range without requiring complex multi-component position adjustment mechanisms
