Detachable Air Chuck Finger Locking for Precise Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air chucks face challenges in maintaining precise alignment between the finger support part and the chuck main body part, leading to free movement of the pair of fingers when detached, requiring additional mechanisms for alignment during automatic replacement.
Innovation Solution
The air chuck incorporates a pair of lock shafts that shift between lock and non-lock positions, linked via mechanisms that secure the finger support part to the chuck main body part, using catch surfaces and press members to maintain alignment and facilitate easy attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the finger support part is made detachable from the chuck main body part, then the adaptability and versatility of the air chuck is improved, but the pair of fingers becomes free and shifts when detached, requiring additional alignment mechanisms
Solution Approach 1:
The air chuck is divided into separable components: a chuck main body part and a finger support part. This segmentation enables the finger support part to be detached and replaced according to different workpiece requirements, improving adaptability while the lock shaft mechanism ensures proper positioning during attachment
Solution Approach 2:
A lock shaft serves as an intermediary element between the finger support part and the chuck main body part. The lock shaft includes a lock projection that engages with a lock recess, acting as a mediator to maintain precise alignment and positional relationship between the detachable components during attachment and replacement operations

AI summary
An air chuck includes: a finger support part including a pair of fingers and a pair of lock shafts; a chuck main body part including an operation mechanism operable to open and close the fingers; and linking mechanisms that detachably link the finger support part to the chuck main body part. Each of the linking mechanisms causes the corresponding lock shaft to shift to a non-lock position so as to render the pair of fingers capable of being opened and closed when the finger support part is linked to the chuck main body part. Each of the linking mechanisms causes the corresponding lock shaft to shift to a lock position and locks the pair of fingers so as to render the pair of fingers incapable of being opened and closed when the finger support part is detached from the chuck main body part.
