Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of changing jaws in adjustable chucks to accommodate workpieces of different sizes is time-consuming, hindering operational efficiency in machining apparatus.
Innovation Solution
A wedge-lock coupling mechanism is employed to quickly connect and disconnect jaws from actuator arms, utilizing a tapered locking surface with teeth to provide a rigid and rapid attachment and release system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional jaw changing process is used, then jaws can be securely attached to actuator arms, but jaw reconfiguration time is excessive
Solution Approach 1:
The jaw coupling mechanism is segmented into modular components: a coupling body with internal threading, a separate actuator arm with external threading, and a quick-release button mechanism. This segmentation allows the jaw to be rapidly attached by screwing the actuator arm into the coupling body and quickly released by pressing the button, dramatically reducing reconfiguration time while maintaining secure attachment during operation.
Solution Approach 2:
The coupling mechanism transitions from a static threaded connection to a dynamic quick-release system. The button-actuated release mechanism allows the connection to rapidly switch between locked and unlocked states, enabling fast jaw changes while maintaining firm attachment during machining operations. This dynamic capability resolves the contradiction between secure attachment and rapid reconfiguration.
2Productivity
If quick-release mechanism is implemented, then jaw swapping speed increases, but connection rigidity may be compromised
Solution Approach 1:
The coupling system is divided into a stable threaded connection portion and a separate quick-release actuation portion. The threaded connection provides rigid, stable attachment between the jaw and actuator arm, while the button mechanism provides rapid release capability without compromising the stability of the connected components during operation.
Solution Approach 2:
The coupling body acts as an intermediary between the actuator arm and the jaw. It features internal threading that receives the actuator arm's external threads, creating a stable mechanical connection. The quick-release button mechanism is integrated into this intermediary coupling body, allowing rapid release while maintaining connection stability during machining through the threaded engagement.

AI summary
A system, in certain embodiments, includes a wedge-lock coupling configured to connect a jaw to an actuator arm of a chuck. The wedge-lock coupling includes a wedge portion having a path of travel between a release position and a lock position, and a locking direction along the path of travel gradually wedges the wedge portion between the actuator arm and the jaw.
