Adjustable Coolant Nozzle on Grinding Machine Wheel Guard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Grinding machines face inefficiencies due to the inability to automatically adjust coolant nozzles to changing grinding tool diameters, leading to suboptimal coolant jet direction and increased downtime for tool changes.
Innovation Solution
The integration of adjustable coolant nozzles on the wheel guard, driven by a spindle housing mechanism, allows for automatic adjustment of coolant jet direction in response to changes in grinding tool diameter, enabling flexible operation without needing to change the wheel guard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the coolant nozzle is firmly integrated into the wheel guard, then the structure is simple and reliable, but the coolant jet direction cannot be adjusted when grinding tool diameter changes
Solution Approach 1:
The coolant nozzle is mounted on the wheel guard in a manner that allows it to be moved or adjusted dynamically. The mounting structure includes adjustment mechanisms (such as threaded adjustments, sliders, or pivot points) that enable the coolant nozzle position to be changed according to the grinding tool diameter, transforming a static fixed mounting into a dynamic adjustable one.
Solution Approach 2:
The position parameters of the coolant nozzle (such as distance from the grinding tool, angle of jet direction) can be changed to adapt to different grinding tool diameters. By adjusting these parameters, the coolant jet can always be directed optimally onto the grinding tool surface regardless of diameter variations.
2Productivity
If the grinding tool diameter changes due to wear or replacement, then productivity is maintained through continuous operation, but the coolant jet misses the grinding tool circumference
Solution Approach 1:
The system incorporates feedback mechanisms where the coolant nozzle position is adjusted based on the actual grinding tool diameter. This can be through manual measurement feedback or automated sensing systems that detect tool wear and trigger相应的 nozzle repositioning to maintain optimal coolant application.
Solution Approach 2:
The coolant nozzle position can be preliminarily adjusted or pre-configured for different tool diameters. Before tool replacement or during scheduled maintenance, the nozzle position is prepared in advance to match the new tool dimensions, ensuring immediate effectiveness upon tool change without disrupting production flow.
3Device complexity
If manual adjustment of coolant nozzle is required, then device complexity is reduced, but time is lost during wheel guard installation
Solution Approach 1:
The mounting structure provides dynamic adjustability with simple mechanisms that enable quick position changes. Features such as quick-release mounts, threaded adjustments with large pitch, or spring-loaded positioning systems allow operators to rapidly reposition the coolant nozzle without complex procedures or specialized tools.

AI summary
The machine has grinding tools (14) selectively stretched to a grinding spindle (12) and accommodated in a storage chamber. A disk protector (16) is selectively stretched to the spindle housing, and a coolant nozzle (20) is adjustably mounted in the disk protector with respect to the grinding tool. A controllable drive (36) i.e. servo-pneumatic drive, for adjusting the coolant nozzle is arranged in the spindle housing and coupled with the coolant nozzle at the disk protector. The controllable drive is decoupled with the coolant nozzle for replacing the disk protector. The controllable drive is selected from a servo-pneumatic drive, a servo-hydraulic drive or electric motor drive.
