Machining Device Multi-Dimensional Workpiece Re-Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing devices for wood and wood-based materials struggle with efficiently machining workpieces with varying contour heights, as they require constant clamping height and limited clamping surfaces, making it difficult to process workpieces with offset edges or those that have already been partially machined.
Innovation Solution
A processing device with relocatable workpiece holders that allow for re-clamping in multiple dimensions, enabling workpieces to be transferred between holders without additional manipulators, and featuring movable clamping elements that can adjust in multiple dimensions to accommodate varying workpiece heights and positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If workpiece holders with fixed clamping jaws are used, then the workpiece maintains constant height and position during clamping, but workpieces with varying contour heights or offset edges cannot be easily machined
Solution Approach 1:
The clamping jaws are made displaceable relative to the workpiece holder in at least one dimension, allowing them to adjust their position dynamically. This enables the workpiece holder to accommodate workpieces with varying heights and contours while maintaining stable clamping, resolving the contradiction between stability and adaptability.
2Device complexity
If only upper and lower bearing surfaces are used for clamping, then the clamping structure remains simple, but workpieces with limited clamping surfaces or already machined lateral profiles cannot be held properly
Solution Approach 1:
The workpiece holder is designed with clamping jaws that can be positioned and oriented in multiple dimensions, enabling it to clamp workpieces not only on upper and lower surfaces but also on lateral surfaces and already machined profiles. This multi-functional capability allows the same holder to adapt to various workpiece geometries without requiring different clamping devices.
3Productivity
If workpieces are transferred between workpiece tables, then different sides of the workpiece can be processed, but the transfer process becomes complex requiring manipulators or additional feeding devices
Solution Approach 1:
The invention combines the workpiece holder with the workpiece table, integrating the holding and transfer functions into a single unit. The workpiece holder is displaceable on the workpiece table, allowing the workpiece to be transferred directly with its holder to another table without requiring separate manipulators or feeding devices, thus maintaining productivity while reducing complexity.
4Illumination intensity
If window frame part widths are reduced to increase light incidence, then more light enters living spaces, but the available clamping surfaces on the workpiece become increasingly limited
Solution Approach 1:
The invention utilizes additional spatial dimensions by allowing clamping jaws to be displaceable in multiple directions relative to the workpiece holder. This enables clamping on lateral surfaces and already machined profiles of narrow window frame parts, effectively using the vertical and lateral dimensions to compensate for the reduced width and limited clamping surface area.
