Welding Torch Gas Diffuser Quick Connect With Double-Start Threads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional welding torches require multiple turns to connect and disconnect gas diffusers from the neck, making the assembly and disassembly process time-consuming.
Innovation Solution
A custom double-start stub ACME thread design for the gas diffuser and welding torch neck, allowing for connection or disconnection in approximately 1.5 turns or less, utilizing a combination of screw threads and threaded grooves with a locking taper for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screw connections are used for gas diffusers and welding necks, then the connection is secure and reliable, but the assembly and disassembly process requires multiple turns and is time-consuming
Solution Approach 1:
The patent applies parameter changes by modifying the thread geometry parameters - specifically using a double-start thread configuration where the lead is twice the pitch. This allows the gas diffuser to be connected or disconnected in approximately 1.5 turns or less while maintaining secure engagement through the optimized thread profile and locking taper geometry
Solution Approach 2:
The invention implements a dynamic balance between connection security and assembly speed through the locking taper mechanism. The taper provides progressive engagement that ensures reliable connection while the double-start thread configuration enables rapid assembly, creating an optimized dynamic interaction between the threading system and locking mechanism
2Reliability
If conventional screw connections are used for gas diffusers and welding necks, then the connection is secure, but the disassembly process is complex and time-consuming
Solution Approach 1:
The patent changes the operational parameters by implementing a double-start thread design with optimized pitch and lead ratios. This configuration reduces the number of turns required for both assembly and disassembly to approximately 1.5 turns or less, making the operation simpler and faster while the locking taper maintains connection security
Solution Approach 2:
The threading system is segmented into a double-start configuration with two independent thread paths that work simultaneously. This segmentation allows the gas diffuser to be quickly engaged or disengaged by rotating through a reduced angular range, simplifying the operation while maintaining secure connection through the distributed thread engagement

AI summary
Some examples of the present disclosure relate to apparatus, systems, and/or methods for providing a quick connect and/or disconnect for a gas diffuser and/or neck assembly, for example, in a welding system. The gas diffuser may include threaded grooves and/or protrusions configured to engage with screw threads and/or channels of the neck assembly. The screw threads, protrusions, threaded grooves, and/or channels may be configured such that the gas diffuser may be quickly connected to, and/or disconnected from, the neck assembly.
