Coaxial Clamp With Rotating Assemblies For Irregular Workpieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clamps find it difficult to securely clamp irregularly shaped workpieces due to fixed clamping angles, limiting their ability to accommodate diverse workpiece geometries.
Innovation Solution
A clamp design featuring a first and second clamping assembly, each with a guide shaft, base, clamps, connection members, buffers, and positioning structures with springs and steel balls, allowing 360-degree rotation along the guide shaft for adjustable clamping, enabling secure fixation of irregularly shaped workpieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the clamp uses a fixed clamping angle design, then the structure is simple, but it cannot securely clamp irregularly shaped workpieces
Solution Approach 1:
The clamp employs rotatable clamping assemblies that can rotate 360 degrees along the guide shaft, transforming the fixed-angle structure into a dynamic, adjustable configuration. This allows the clamping assemblies to adapt to various workpiece geometries while maintaining operational simplicity through the rotation mechanism
Solution Approach 2:
The clamp is divided into multiple independent clamping assemblies (first and second clamping assemblies), each capable of independent rotation and adjustment. This segmentation allows each assembly to be positioned optimally for different sections of irregular workpieces, enhancing overall adaptability without requiring complete structural redesign
2Adaptability or versatility
If the clamp allows 360-degree rotation of clamping assemblies, then it can clamp irregular workpieces freely, but the device complexity increases
Solution Approach 1:
The clamping assemblies are nested on the guide shaft, with each assembly containing its own buffer and positioning structures that fit within the overall clamp framework. This nesting allows the rotation mechanism to be compact and integrated, reducing overall device complexity while enabling 360-degree adjustment
Solution Approach 2:
The buffer and positioning structure (with steel balls and springs) enable the clamping assemblies to self-position and self-lock during rotation. This self-service mechanism eliminates the need for complex external locking devices or motors, achieving 360-degree adjustability through passive mechanical means

AI summary
A clamp contains: a first clamping assembly, a second clamping assembly, and a guide shaft. The first clamping assembly includes a base, a first clamper, a first connection member, and a first buffer. The base has a grip, an operation lever, and a release lever. The base further includes a release structure driven by the release lever to remove the base from the guide shaft. The second clamping assembly includes a second clamper, a second connection member, and a second buffer. The first buffer accommodates the guide shaft, and the second buffer is fitted on and is rotated with respect to an outer wall of the second connection member. The second clamper is fitted on the second buffer and the second connection member, the second clamper is rotatable relative to the second connection member, and the second clamper and the second buffer are connected with the second connection member.
