Welding Torch Bracket Layout for Stable Teaching Handle Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a teaching handle is mounted on a welding robot near the bending portion of the torch body, it is challenging to accurately teach the welding behavior while preventing the torch distal end from swinging, due to the moment applied by the teaching handle.
Innovation Solution
A welding robot design that includes a bracket with a detachable securing mechanism, allowing the teaching handle to be mounted in a way that the handle distal end faces the bending portion of the torch body, thereby applying force through an arm portion that minimizes swing of the torch distal end.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the teaching handle is mounted directly to the bending portion of the torch body, then the teaching operation can be performed, but the torch distal end swings due to the moment applied by the teaching handle
Solution Approach 1:
A bracket is introduced as an intermediary component between the teaching handle and the torch body. The bracket includes a bracket body detachably secured to the connecting plug and a handle support portion that supports the teaching handle. This intermediary structure allows the teaching handle to be positioned such that its distal end faces the bending portion, enabling teaching operations while the bracket absorbs and distributes the applied forces, preventing direct moment transmission that would cause torch distal end swing.
2Stability of the object's composition
If the teaching handle is mounted away from the bending portion of the torch body, then the torch distal end swing is reduced, but the teaching precision deteriorates
Solution Approach 1:
The bracket extends in a direction away from the second portion of the torch body (from bending portion to distal end), creating a spatial arrangement where the teaching handle is positioned in a different dimensional plane. This dimensional repositioning allows the teaching handle distal end to face the bending portion for precise teaching, while the bracket's extended structure provides leverage and stability to prevent torch distal end swing during operation.

AI summary
A coupling portion includes a retaining mechanism that retains a torch proximal end of a torch body via a connecting plug such that a torch distal end is swingable with respect to the coupling portion. A teaching handle is mounted to a welding torch via a bracket. The bracket comprises: a bracket body detachably secured to the connecting plug and provided in parallel to a first portion of the torch body from the torch proximal end to a bending portion, with a distance therefrom; and a handle support portion that supports the teaching handle such that a handle distal end of the teaching handle is disposed at a position facing the bending portion.
