Laser Machining Head Coupling for Rotatable Auxiliary Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machining units for thermal machining, such as laser welding, face interference and collision issues due to fixed auxiliary modules, which limits their application spectrum and increases the risk of damage during workpiece machining.
Innovation Solution
The machining unit incorporates a coupling device that allows auxiliary modules to be selectively coupled or uncoupled from a rotary drive device, enabling rotational positioning and movement out of the machining area when not required, thereby reducing interference contours and enabling flexible operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If auxiliary modules are fixed to the machining unit, then functional reliability is improved, but interference contour and collision risk increase
Solution Approach 1:
The auxiliary module is made dynamically positionable through a coupling device that enables selective coupling and uncoupling from the rotary drive device. This dynamic configuration allows the system to switch between a coupled state (for functional reliability) and an uncoupled state (for reduced interference contour), resolving the contradiction between reliability and harmful interference.
2Adaptability or versatility
If auxiliary modules are rotatable about the beam incidence axis, then application spectrum is improved, but collision risk with workpiece increases
Solution Approach 1:
The system employs dynamic coupling control where the auxiliary module can be selectively coupled to enable rotation for diverse machining applications, or uncoupled to minimize collision risk. This dynamic adaptability allows the system to adjust its configuration based on the specific machining task and workpiece geometry.
3Ease of operation
If auxiliary module is always coupled to rotary drive device, then rotational positioning capability is improved, but device complexity increases
Solution Approach 1:
The coupling device is segmented into separable coupling and uncoupling states, allowing the auxiliary module to be selectively attached or detached from the rotary drive device. This segmentation enables rotational positioning capability when needed while simplifying the overall device configuration when the auxiliary module is not required, thereby reducing device complexity.
