Concrete Grinder Dust-Proof Cover Alignment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concrete grinders face precision issues due to wear of the grinding disk, leading to uneven dust-proof cover alignment, which causes the main body and grinding disk to incline, affecting the grinding precision.
Innovation Solution
A concrete grinder design featuring a drive ring with adjustable drive blocks and grooves, an adjusting assembly, and a locking mechanism that allows for realignment of the dust-proof cover to maintain parallelism with the grinding disk, reducing deformation and inclination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the grinding disk is pressed against the ground to maintain parallelism, then the lower surface of the dust-proof cover can be kept flush with the grinding disk, but the dust-proof cover deforms and the main body and grinding disk incline, affecting precision
Solution Approach 1:
The dust-proof cover is designed to be movable relative to the main body through a guide groove and guide block mechanism. This allows the dust-proof cover to dynamically adjust its position to remain flush with the grinding disk surface during operation, while the main body remains stable. The dynamic adjustment eliminates the need to deform the dust-proof cover by pressing, thereby preventing inclination of the main body and maintaining grinding precision.
2Stability of the object's composition
If pressure is applied by hand to press the dust-proof cover against the ground, then alignment is improved, but the main body and grinding disk become inclined due to uneven pressure, reducing precision
Solution Approach 1:
The dust-proof cover automatically adjusts its own position through the guide groove and guide block mechanism to remain aligned with the grinding disk. This self-adjusting mechanism eliminates the need for manual pressing, thereby avoiding the inclination caused by uneven hand pressure and maintaining grinding precision without requiring operator intervention.
3Object-affected harmful factors
If the dust-proof cover is made deformable to press against the ground, then it can block dust effectively, but the main body and grinding disk incline, affecting precision
Solution Approach 1:
Instead of making the dust-proof cover deformable, the invention makes it movable along a guide groove. This dynamic positioning allows the cover to maintain flush alignment with the grinding disk for effective dust blocking, while the rigid structure prevents inclination of the main body, thereby maintaining grinding precision.
4Strength
If the dust-proof cover is fixed rigidly to the main body, then structural stability is improved, but it cannot adapt to wear of the grinding disk, causing misalignment
Solution Approach 1:
The dust-proof cover is connected to the main body through a semi-rigid linkage consisting of a guide groove and guide block. This provides sufficient structural stability while allowing relative movement along the guide groove. As the grinding disk wears, the dust-proof cover can move to maintain alignment, combining the benefits of both rigid and flexible connections.
