Lubricant Coolant Spray Nozzle for Rotating Tool Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machining apparatuses face inefficiencies in fluid distribution, as external fluid jets splash and fail to provide broad coverage due to the high-speed rotation of tools and workpieces, leading to increased wear and temperature issues.
Innovation Solution
A spray nozzle assembly with an outer ring and inner member that directs a tubular fluid stream around the cutting tool, utilizing a diffuser section and flow passages to create a focused, conical or cylindrical jet that counteracts rotation and maintains fluid contact with the tool, reducing wear and temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If external fluid jets are used to convey fluid from an external source, then the system is simpler to implement, but the fluid splashes away due to rotation and coverage is limited to a small area
Solution Approach 1:
The spray nozzle assembly is nested within the tool structure, with the outer ring containing flow passages and the inner member positioned centrally. The fluid delivery system is integrated into the tool itself rather than being external, allowing the fluid to be delivered from within the rotating component where it can effectively reach the workpiece interface across a broader area.
Solution Approach 2:
The outer ring is segmented into multiple flow passages that distribute fluid through different pathways. This segmentation allows fluid to be delivered to multiple locations simultaneously, expanding the effective coverage area while maintaining a compact integrated structure within the tool.
2Area of stationary object
If multiple external fluid jets are employed to achieve broader coverage, then the fluid coverage area increases, but the device complexity and cost increase
Solution Approach 1:
The integrated spray nozzle assembly serves multiple functions within a single component structure. The outer ring with its multiple flow passages acts as both the fluid distribution system and the structural element, eliminating the need for multiple separate external jets while achieving comprehensive coverage through the unified design.
3Reliability
If twisted bores are formed in the tool for conveying fluid, then fluid can be delivered through the tool, but the manufacturing process becomes complex and costly
Solution Approach 1:
Instead of forming complex twisted bores through the entire tool, the fluid delivery path is segmented into discrete flow passages within the outer ring. These passages can be manufactured using simpler processes such as drilling and machining, avoiding the need for complex twisted bore formation while still achieving reliable fluid delivery through the tool to the workpiece interface.

AI summary
A spray nozzle assembly for a machining apparatus includes an outer ring extending from a first axial inlet end to a first axial outlet end. The outer ring contains a flow distribution section that extends inwardly from the ends of the first axial inlet towards the first axial outlet and terminating therebetween. The outer ring includes a diffuser section extending inwardly from the first axial outlet end towards and ends at the flow distribution section. The outer ring has a first interior area defined by a first interior surface which contains a diffuser surface aligned with the diffuser section and multiple flow passages formed within and aligned with the flow distribution section and overlaps into the diffuser surface, and at least one guide surface and an abutment surface; and an inner member extending into the first interior area.
