Supplementary Workpiece Support Assembly With Pivoting Sliding Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing supplementary support assemblies for machine tools, such as cross-cut mitre saws, lack flexibility in accommodating various workpiece sizes and shapes, particularly for plate-like and strip-like materials, due to limited adjustability and rigidity.
Innovation Solution
A supplementary support assembly with a supporting body that is pivotable and/or slidable relative to the base, featuring a supplementary supporting surface that can be detachably fixed at different angles and positions, and an adjustable transverse stop body that can be positioned at various angles to the supplementary supporting surface, allowing for enhanced support and machining of diverse workpieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed supplementary support assembly is used, then the structure is simple and stable, but it cannot accommodate various workpiece sizes and shapes
Solution Approach 1:
The supporting body is made movable relative to the support body through sliding bearings and pivoting bearings, allowing it to be positioned at different locations and angles. This dynamic capability enables the supplementary support assembly to adapt to various workpiece sizes and shapes while maintaining a relatively simple overall structure.
Solution Approach 2:
The supplementary support assembly is divided into separable components: the support body that attaches to the machine tool, and the supporting body that provides the supplementary supporting surface. This segmentation allows independent adjustment of each component, enhancing versatility without significantly increasing structural complexity.
2Adaptability or versatility
If the supporting body is made movable with sliding and pivoting bearings, then flexibility is improved, but the device complexity increases
Solution Approach 1:
The supporting body incorporates sliding bearings for linear movement and pivoting bearings for angular adjustment, enabling flexible positioning. These bearing mechanisms provide the necessary degrees of freedom while maintaining mechanical simplicity through standard bearing components.
Solution Approach 2:
The position and orientation parameters of the supporting body can be continuously adjusted within certain ranges using the bearing mechanisms. This parameter variability allows adaptation to different workpiece configurations without requiring multiple discrete components.
3Area of stationary object
If the supplementary supporting surface is enlarged, then support for plate-like and strip-like workpieces is improved, but the device complexity increases
Solution Approach 1:
The supporting body can be extended or repositioned to provide a larger supplementary supporting surface area when needed for plate-like and strip-like workpieces. The dynamic positioning capability allows the support surface to be optimized for different workpiece dimensions without requiring a permanently large structure.
