Gripping Device Exchangeable Fingers Centering Cone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gripping devices with jaws that can be moved in a base body lack secure and easy attachment mechanisms for gripping fingers, particularly those that rise above the base body, leading to difficulties in accurate placement and flexibility in use.
Innovation Solution
A gripping device with a fastening section that rises above the base body, featuring a recess for the gripping finger and a clamping screw with a centering cone and counter-cone for precise alignment, along with a quick-change interface for easy attachment and detachment of fingers, allowing for secure clamping and flexible operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fastening section that rises above the base body is provided for attaching gripping fingers, then the flexibility and range of use of the gripping device is expanded, but accurate placement of the gripping fingers becomes difficult due to clearance between the mounting portion and the recess faces
Solution Approach 1:
A clamping screw is introduced as an intermediary element between the fastening section and the gripping finger. The clamping screw features a conical clamping surface that interfaces with a corresponding conical recess in the gripping finger, creating a precise mating relationship that eliminates placement errors while maintaining the benefits of the rising fastening section
Solution Approach 2:
The invention changes the geometric parameters of the clamping interface by providing surfaces running perpendicular to the direction of travel on the fastening section, and matching conical surfaces on the gripping finger. This parameter change enables precise alignment and placement while maintaining adaptability
2Reliability
If a clamping mechanism is provided to secure the gripping finger on the fastening section, then the reliability of attachment is improved, but the device complexity increases due to additional components
Solution Approach 1:
The attachment mechanism is segmented into distinct functional elements: the rising fastening section for positioning, perpendicular clamping surfaces for alignment, a conical recess for reception, and a clamping screw for securing. This segmentation allows each element to perform its specific function efficiently while keeping the overall structure manageable and understandable
Solution Approach 2:
The conical clamping surface and conical recess work together in a self-centering manner, where the geometry itself provides alignment and secure attachment without requiring additional complex positioning mechanisms. The clamping screw simply needs to be inserted and tightened, and the conical surfaces automatically ensure proper alignment and secure attachment

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables secure and easy attachment of gripping fingers, enhancing the flexibility and range of use of the gripping device without compromising existing advantages, ensuring accurate placement and efficient operation.
Implementation Method 1
the clamping screw has a centering cone at the free end... the gripping finger has a counter-cone on its side facing the free end of the clamping screw... the centering cone and counter-cone can slide on one another without line contact
Implementation Method 2
the fastening section, with gripping fingers arranged thereon, can be clamped and/or braced by a free end of the clamping screw in the recess on the surface facing the free end of the clamping screw against the surface facing away from the free end
Implementation Method 3
the clamping screw can be releasably arranged on the fastening section or on the gripping finger... the fastening section can be clamped and/or braced by a free end of the clamping screw
