Solution Overview
Problem
Current vice structures with rigid clamping surfaces struggle to securely clamp work pieces with non-parallel surfaces, leading to unstable clamping and subsequent processing issues.
Innovation Solution
A vice jaw deflecting structure featuring a guide slot, lead screw with opposing spiral threads, and flexible jaws that can deflect left or right, allowing for precise clamping of non-parallel surfaces through a -shaped stop block and limiting component design, enabling stable clamping and easy jaw replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If rigid plane surfaces are used for clamping, then the structure is simple and easy to manufacture, but the clamping stability deteriorates when clamping non-parallel surfaces
Solution Approach 1:
The jaw is designed with a convex wall surface that allows dynamic deflection to the left or right, transforming the static rigid structure into a dynamic adaptable one. This enables the jaw to automatically adjust to non-parallel clamping surfaces while maintaining structural simplicity
Solution Approach 2:
The jaw's geometric parameters are designed to allow controlled deflection through the convex wall surface configuration. By changing the contact geometry from a fixed plane to a curved surface that can deflect, the system adapts to varying clamping conditions without complicating the overall structure
2Ease of manufacture
If rigid plane surfaces are used for clamping, then the structure is simple, but the adaptability deteriorates for non-parallel surfaces
Solution Approach 1:
The jaw incorporates a convex wall surface that enables left-right deflection, allowing the simple rigid structure to dynamically adapt to non-parallel surfaces. This maintains manufacturing simplicity while achieving the needed adaptability
Solution Approach 2:
The jaw design incorporates a flexible deflection capability through the convex wall surface, allowing the clamping surface to bend and conform to non-parallel workpiece surfaces while maintaining the overall rigid structure for manufacturing simplicity
