Turret Tool Post Structure for Non-Turning Laser Head Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing turret tool posts, machining devices like laser heads require turning during workpiece machining, which can be inefficient and may cause issues with coolant spray and cable twisting during high-speed operations.
Innovation Solution
A turret tool post design featuring a turning part for tool selection and a non-turning part with a fixed wall for attaching machining bodies, where the machining body is positioned to face the workpiece without turning, and is covered by an inner and outer cover to prevent coolant and cable twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the machining body is attached to the turning part to enable tool selection by turning, then tool versatility is improved, but the machining body must turn during operation causing cable twisting and coolant spray issues
Solution Approach 1:
The turret tool post is divided into two independent parts: a turning part for tool selection and a non-turning part for mounting the machining body. The turning part can rotate to select different tools, while the non-turning part remains stationary to prevent cable twisting and coolant spray issues. This segmentation allows each part to perform its specific function without the drawbacks of the other.
Solution Approach 2:
An intermediary structure (the non-turning part with fixed wall part) is introduced between the turning part and the machining body. This intermediary allows tool selection through turning of the turning part while preventing the machining body from turning, thus resolving the contradiction between tool versatility and operational reliability.
2Reliability
If the machining body is fixed to a non-turning part inside the turning part, then turning during machining is prevented, but access to the workpiece may be restricted
Solution Approach 1:
The system dynamically switches between two states: during tool selection, the turning part rotates to bring different tools into position; during machining, the turning part is locked in place and only the machining body moves toward the workpiece. This dynamic operation sequence ensures both reliable no-turning machining and proper workpiece access.
Solution Approach 2:
The machining body is positioned in a different spatial dimension (inside the turning part but on a non-turning part) rather than being directly attached to the rotating component. This dimensional arrangement allows the machining body to approach the workpiece from within the turning mechanism without being constrained by its rotation.

AI summary
To prevent a cable connected to a machining body from being twisted, and also to prevent coolant from spraying to the machining body when another tool is used, a turret tool post (100) includes a turning part (20) having a plurality of turret surfaces (22) on which tools (90) for machining a workpiece (210) are mounted, the turning part being configured to select any one of the tools (90) for use in the machining of the workpiece (210) by turning; a non-turning part (30) on which a laser head (80) of a laser machining device different from the tool (90) is mounted, the non-turning part being arranged inside the turning part (20), an optical fiber cable (85) being connected to the laser head (80); and a cut part (23) (machinable part) that allows machining by the laser head (80) to the workpiece (210) under a state in which the laser head (80) is selected.
