Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cylindrical grinding machines face challenges in achieving high-precision machining due to bending moments and reversal of force during grinding wheel movement, which affects control behavior and precision, especially when working with round workpieces.
Innovation Solution
The grinding wheel is guided vertically upwards, with the workpiece positioned below, allowing the grinding wheel's axis of rotation to move in the same vertical plane, eliminating force reversal and enabling precise alignment, and the machine is designed with a modular structure and portal-like frame for space efficiency and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the grinding wheel is moved horizontally on a horizontal plane, then the machine structure is simple, but the axle drive forces reverse during preliminary or return movement, causing disadvantageous control behavior and impaired precision
Solution Approach 1:
The patent inverts the conventional horizontal grinding wheel arrangement by positioning the grinding wheel vertically above the workpiece. The grinding wheel axis is oriented vertically and moves vertically along the workpiece axis, rather than horizontally. This inversion eliminates the force reversal problem during preliminary and return movements, as the grinding wheel always approaches the workpiece from the same direction (from above), maintaining consistent drive force direction and improving control behavior and positioning precision in the thousandth of a millimeter range.
2Manufacturing precision
If the grinding wheel is arranged vertically above the workpiece, then force reversal is eliminated and control behavior improves, but the machine requires a portal-like frame structure that increases device complexity
Solution Approach 1:
The patent segments the machine into modular components: a portal-like frame structure supporting the grinding wheel assembly, a separate workpiece holding device, and independent drive mechanisms. This modular segmentation allows the complex portal structure to be constructed from standardized components, facilitating easier assembly, maintenance, and adaptation while achieving the desired vertical arrangement that eliminates force reversal.
3Ease of manufacture
If the machine is designed with fixed structure, then manufacturing is simpler, but the machine cannot be easily positioned or repositioned in the intended location
Solution Approach 1:
The patent introduces dynamic positioning capabilities to the machine base through adjusting rollers that enable the machine to be moved and repositioned on the factory floor. The machine frame incorporates mounting features and adjustment mechanisms that allow flexible positioning while maintaining structural integrity during operation. This dynamic positioning capability complements the otherwise fixed rigid structure, providing both manufacturing simplicity and operational flexibility.
