Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grinding machines with coolant systems require complex setup, occupy space, and need frequent adjustments due to wear or replacement of grinding wheels, leading to inefficiencies and operational challenges.
Innovation Solution
A grinding wheel assembly with an integrated coolant passage system that allows coolant to flow through the tool holder, mounting shaft, and grinding wheel, eliminating the need for external pipelines and nozzles, and enabling adjustable mounting for optimal coolant distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional coolant system with external pipelines and nozzles is used, then coolant can be supplied to the grinding wheel, but the setup becomes complex and time-consuming
Solution Approach 1:
The patent integrates the coolant delivery function directly into the grinding wheel assembly by incorporating coolant passages within the wheel structure itself. This merging of the coolant system with the grinding wheel eliminates the need for separate external pipelines and nozzles, thereby simplifying the overall system and reducing setup complexity while maintaining effective coolant supply to the grinding zone
2Ease of operation
If external pipelines and nozzles are installed for coolant delivery, then coolant can reach the contact point, but space inside the grinding machine is occupied
Solution Approach 1:
The patent embeds the coolant passages within the internal structure of the grinding wheel assembly, nesting the coolant delivery system inside the wheel itself rather than placing it externally. This nesting approach allows coolant to be delivered effectively to the contact point while occupying minimal additional space in the grinding machine, as the coolant channels are integrated into the existing wheel structure
3Reliability
If the nozzle position is adjusted to accommodate wear or replacement of the grinding wheel, then coolant can continue to cool effectively, but time and operational trouble are incurred
Solution Approach 1:
The patent designs the grinding wheel assembly with self-adjusting coolant delivery capability through its internal passage structure. The coolant passages are configured to automatically adapt to the position of the grinding wheel contact point, eliminating the need for manual nozzle adjustments when the wheel wears or is replaced. This self-service mechanism ensures continuous effective cooling without requiring operational intervention or time for adjustments
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The grinding wheel assembly effectively cools both the grinding wheel and workpiece without the need for external coolant systems, reducing setup time, saving space, and improving operational efficiency by allowing for direct coolant ejection at the contact point.
Implementation Method 1
a coolant flows through the pipeline 922 and is ejected from the at least one nozzle 921 toward a contact point of the grinding wheel 91 and the workpiece 80 to cool down the grinding wheel 91 and the workpiece 80
Implementation Method 2
coolant to flow through the tool holder, mounting shaft, and grinding wheel, enabling adjustable mounting for optimal coolant distribution

AI summary
A grinding wheel assembly has a tool holder, a mounting shaft connected to the tool holder, and a grinding wheel mounted on the mounting shaft. The tool holder has a first coolant passage defined through the tool holder. The mounting shaft has a second coolant passage communicating with the first coolant passage. The grinding wheel has multiple third coolant passages defined through the grinding wheel and communicating with the second coolant passage. The first coolant passage, the second coolant passage, and the multiple third coolant passages are utilized for a coolant to flow through. Thereby, the grinding wheel and a workpiece can be cooled down without setting up any pipeline and nozzle for the coolant in a grinding machine.
