Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing grinding apparatuses face difficulties in efficiently replacing the grinding wheel due to the obstruction caused by the nozzle, which requires detachment or repositioning, leading to increased work time and potential shifts in the grinding water jetting position.
Innovation Solution
A grinding apparatus with a movable nozzle biased upward by a mechanism that includes an upper limit stopping section, allowing the nozzle to maintain a fixed position even when the grinding unit is moved upward, creating a gap for wheel replacement without needing nozzle repositioning or detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the nozzle is disposed directly below the grindstone to supply grinding water to the processing area, then the grinding water can be supplied effectively, but the nozzle becomes an obstacle when the grinding wheel needs to be replaced
Solution Approach 1:
The nozzle is designed to be movable rather than fixed, allowing it to adapt its position based on operational requirements. During grinding, the nozzle moves to supply water to the processing area, and during wheel replacement, it moves away to avoid obstruction, thus resolving the contradiction between reliable water supply and ease of wheel replacement
Solution Approach 2:
The nozzle function is separated from the grinding wheel assembly, allowing independent movement and positioning of the nozzle relative to the grindstone. This segmentation enables the nozzle to be positioned for water supply during grinding and repositioned or removed from the path during wheel replacement operations
2Manufacturing precision
If the nozzle is fixed in position to ensure consistent grinding water jetting, then the jetting position remains stable, but the nozzle obstructs the replacement of the grinding wheel
Solution Approach 1:
The nozzle transitions from a fixed position to a dynamic, movable position that can be adjusted based on the operational phase. During grinding, it maintains a stable position for consistent water jetting, and during replacement, it moves to a different position, eliminating the need for detaching or repositioning the nozzle and reducing replacement time
3Ease of operation
If the nozzle is made movable to facilitate grinding wheel replacement, then the replacement work becomes easier, but the nozzle position may shift affecting grinding water jetting accuracy
Solution Approach 1:
The nozzle is designed with controlled movability, allowing it to change position only when needed for wheel replacement. During grinding operations, the nozzle remains in a fixed, predetermined position that ensures accurate grinding water jetting, thus maintaining precision while enabling ease of replacement when required

AI summary
A grinding apparatus includes a grinding unit, a grinding feeding mechanism, and a grinding water supply unit. The grinding water supply unit includes a nozzle that jets grinding water to grindstones, and a biasing mechanism that biases the nozzle upward. The nozzle is configured to be movable downward against the upward biasing according to a downward movement of the grinding unit. The grinding apparatus further includes an upper limit stopping section that sets an upper limit position for upward movement of the nozzle biased upward by the biasing mechanism, for forming a gap through which the grinding wheel is passed, between the nozzle and the mount.
