Multipurpose Chuck Combining Jaws, Vise Grip, and Magnetic Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machining chucks are limited in their ability to handle workpieces of different sizes and shapes, requiring multiple chuck changes for proper alignment and machining, and lack a single solution that integrates radially movable jaws, vise grip, and magnetic attachments for precise and reproducible clamping.
Innovation Solution
A multipurpose chuck integrating three or more radially movable jaws, vise grip, and magnetic workpiece attachments, allowing for gripping of workpieces by inner or outer diameter, non-uniform cylindrical shapes, and magnetic attraction, with interchangeable jaw plates and magnet actuation for precise clamping and machining of both hollow and solid workpieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple separate chucks are used for different workpiece types, then each workpiece can be properly aligned and machined, but the time required for chuck changes and setup increases
Solution Approach 1:
The chuck device integrates multiple chuck types (three-jaw self-centering chuck, two-jaw vise grip chuck, and magnetic chuck) into a single universal fixture. The faceplate can be configured with different jaw assemblies and magnetic pole arrangements to handle various workpiece shapes and sizes, eliminating the need to change between separate chucks for different workpiece types while maintaining precise alignment capabilities
Solution Approach 2:
The chuck incorporates movable and adjustable components including radially movable jaws controlled by actuators, shiftable plates for magnetic pole arrangement, and interchangeable jaw plates. These dynamic elements allow the chuck to adapt its configuration real-time to match different workpiece geometries, providing both versatility and precision without requiring physical chuck changes
2Adaptability or versatility
If conventional chucks with fixed jaw configurations are used, then the structure remains simple, but the ability to handle different shaped workpieces is limited
Solution Approach 1:
The chuck is divided into modular functional sections: three-jaw self-centering mechanism, two-jaw vise grip mechanism, and magnetic pole assemblies. Each section can be independently activated or deactivated based on workpiece requirements. The faceplate is segmented to accommodate different jaw configurations and magnetic pole arrangements, allowing selective engagement of specific chuck types without complicating the overall structure
Solution Approach 2:
Different regions of the chuck faceplate are equipped with specialized features tailored to specific workpiece types. The three-jaw section provides radial centering for cylindrical workpieces, the two-jaw section offers clamping for irregular shapes, and magnetic pole regions provide holding force for ferromagnetic materials. Each local region maintains its specific function while contributing to the overall versatility of the unified chuck system

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise and reproducible clamping of various workpieces, reducing the need for chuck changes and allowing high-precision machining of inner and outer surfaces with uniform wall thickness, preventing distortion and eccentric location.
Implementation Method 1
A conventional magnetic chuck comprises a shiftable plate in a frame structure movable in the direction of the arrangement of magnetic pole face portions of a work supporting faceplate. Pole pieces made of soft iron and permanent magnets are alternately arranged

AI summary
A multipurpose chuck having provisions for gripping the outer diameter of workpieces; alternatively, the inner diameter of workpieces; alternatively gripping parts by a two vise jaw, or in combination with a magnet attraction. The chuck having six radially movable jaws that can be used in combination, or by itself with vise grip jaws, which can be used in combination or by itself with a magnetic workpiece attachment in a single chuck.
