Wedge-Locked Compensation Assembly for Clamping Position Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Positioning tolerances between pull-in nipples on workpieces or workpiece pallets and receptacles in clamping devices often result in misalignment, preventing simultaneous insertion of all pull-in nipples into their assigned receptacles, which hampers precise machining processes.
Innovation Solution
A compensation device that allows the carrier to be displaced relative to the base along perpendicular displacement directions, utilizing a clamping device with wedge elements and a movement device to generate linear movement, enabling precise alignment and locking of the carrier to the base, thereby compensating for positional tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If rigid positioning of the carrier relative to the base is used, then manufacturing precision is improved, but positioning tolerance compensation capability deteriorates
Solution Approach 1:
The carrier is made displaceable relative to the base along perpendicular displacement directions, transforming the rigid positioning system into a dynamic one. This allows the carrier to be positioned precisely when needed while also being adjustable to compensate for positioning tolerances, resolving the contradiction between precision and adaptability.
Solution Approach 2:
The system allows changing the positional parameters of the carrier relative to the base by displacing it along perpendicular directions. This parameter adjustment capability enables both precise positioning and tolerance compensation depending on the operational requirements.
2Adaptability or versatility
If the carrier is made displaceable to compensate for positioning tolerances, then adaptability is improved, but positioning precision deteriorates
Solution Approach 1:
The system transitions between dynamic (displaceable for tolerance compensation) and static (locked for precise positioning) states. The locking device enables the carrier to be securely fixed once positioned, ensuring that adaptability does not compromise precision during operation.
Solution Approach 2:
The carrier is first displaced to the desired position to compensate for tolerances, then locked in place before machining operations. This preliminary positioning action ensures both tolerance compensation and subsequent precision are achieved.
3Stability of the object's composition
If a locking device is added to secure the carrier to the base, then positioning stability is improved, but device complexity increases
Solution Approach 1:
The wedge elements utilize the self-locking property of friction to maintain the carrier's position. Once the carrier is displaced to the desired position, the friction between the wedge elements and their guides automatically maintains stability without requiring additional active locking mechanisms, reducing overall system complexity.
