Universal Clamp Assembly with Adjustable Arm for Irregular Workpieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamp assemblies are limited in their ability to hold irregularly shaped parts of varying lengths, widths, and thicknesses, and often require specialized fixtures, which can be costly and impractical for limited production quantities, and are not universally adaptable for different machining operations or machine tables.
Innovation Solution
A universal clamp assembly featuring an elongate tubular base with an adjustably secured clamp arm and an adjustment screw, allowing for adjustable angle and position, along with a supplementary clamping block for securing cylindrical components, enabling secure clamping of diverse workpiece shapes and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If specialized fixtures are produced for each part instance, then the ability to hold irregularly shaped parts is improved, but the cost and time required increases significantly
Solution Approach 1:
The clamp assembly is designed with an adjustable clamp arm that can be positioned at multiple angles and locations along the base, allowing a single fixture to hold various irregularly shaped parts instead of requiring dedicated fixtures for each part type
Solution Approach 2:
The clamp arm is made adjustable through threaded connections and slots, enabling dynamic repositioning to accommodate different part geometries, sizes, and orientations, transforming a static specialized fixture into a versatile adaptive tool
2Adaptability or versatility
If fixed-angle clamp arms are used, then the structure is simpler, but the adaptability to different workpiece positions is reduced
Solution Approach 1:
The clamp arm incorporates adjustable elements including threaded shafts, nuts, and slots that enable repositioning at multiple angles and locations, transforming a simple fixed structure into an adaptable dynamic system
Solution Approach 2:
The clamp arm is divided into separable components (arm, shaft, nut, slot) that can be independently adjusted and reconfigured, allowing flexibility in positioning without requiring complete redesign of the entire structure
3Reliability
If clamps are designed for specific machine tables with T-slots, then the clamping stability is improved, but the portability and applicability to other machines is reduced
Solution Approach 1:
The base is designed with a universal mounting system featuring slots and holes that can accommodate various machine table configurations (T-slots, drill press tables, chop saws, band saws), allowing the same clamp assembly to provide stable clamping across different machines without modification

AI summary
A universal clamp assembly includes an elongate tubular base, a clamp arm adjustably secured to the tubular base at a threaded connection and an adjustment screw that adjusts the angle of the clamp arm relative to an upper surface of the base. Various workpieces can be secured between the clamping arm and the base. An optional clamping block is provided for cooperating with the clamping arm to secure cylindrical workpieces therebetween. In addition, workpieces can be inserted through the tubular base and secured.
