Grinding Stone Jet Cleaning to Prevent Debris Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grinding apparatuses face inefficiencies in removing grinding wastes from the grinding stone surface during processing, leading to decreased processing efficiency and shorter grinding stone lifespan.
Innovation Solution
A grinding apparatus with a fluid injection nozzle that injects fluid at a position opposite to the processing point on the grinding stone's outer circumferential surface, using high-pressure grinding oil to blast away wastes, while sharing a common pump with the grinding oil supply apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If grinding oil is supplied only to the processing point, then the grinding process can be maintained, but grinding wastes accumulate on the grinding stone surface reducing efficiency and lifespan
Solution Approach 1:
The invention extracts the waste removal function from the grinding oil supply system by adding a separate fluid injection apparatus. The fluid injection nozzle is positioned to inject fluid onto the grinding stone surface at a location different from the processing point, specifically at a position where waste accumulates, thereby separating the cooling/lubrication function from the waste removal function and enabling effective waste elimination.
Solution Approach 2:
The invention introduces fluid (water or air) as an intermediary substance to remove grinding wastes from the grinding stone surface. This intermediary fluid is injected at a specific position on the grinding stone and carries away the waste particles, preventing their accumulation and the associated harmful effects on processing efficiency and grinding stone lifespan.
2Object-generated harmful factors
If a separate waste removal system is added, then waste removal efficiency improves, but device complexity increases
Solution Approach 1:
The invention makes the pump universal by having it perform multiple functions: it supplies grinding oil to the processing point through the grinding oil supply nozzle and simultaneously supplies fluid (water or air) to the grinding stone surface through the fluid injection nozzle. This multi-functionality eliminates the need for a separate waste removal system while achieving effective waste elimination.
Solution Approach 2:
The invention merges the grinding oil supply function and the waste removal function into a single integrated system. Both the grinding oil supply nozzle and the fluid injection nozzle are connected to the same pump, combining two previously separate functions into one unified apparatus, thereby reducing device complexity while maintaining waste removal effectiveness.
3Productivity
If multiple nozzles are used for different functions, then functional effectiveness improves, but space requirements increase
Solution Approach 1:
The invention positions the fluid injection nozzle such that it is located near or at the same position as the grinding oil supply nozzle. Both nozzles are arranged in close proximity to each other, with the fluid injection nozzle positioned to inject fluid onto the grinding stone surface at a location different from the processing point. This nested arrangement allows multiple functional nozzles to occupy minimal space while maintaining their respective functional effectiveness.
