Solution Overview
Problem
Conventional inclination angle adjusting systems for vertical surface grinders face challenges in accurately adjusting minute angle degrees and securing the rigidity of the workpiece attaching device, leading to difficulties in achieving high accuracy and operability.
Innovation Solution
The system employs a support and movable body with obliquely inclined surfaces and spherical coupling means, allowing for precise adjustment of the workpiece attaching surface's inclination angle through surface contact and fluid pressure cancellation, enhancing the device's rigidity and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the workpiece attaching section is swung or pivoted directly about the horizontal axis to adjust the inclination angle, then the adjustment mechanism is simple, but it is difficult to adjust a minute angle degree
Solution Approach 1:
The patent introduces a pivot section as an intermediary element between the rotating table and the workpiece attaching section. The pivot section enables the workpiece attaching section to be inclined relative to the rotating table while maintaining a clear separation of functions, allowing for precise inclination angle adjustment through the pivot mechanism rather than direct pivoting.
2Adaptability or versatility
If the workpiece attaching section is supported on the rotating table via the pivot section and the height-adjustment screw mechanism, then the inclination angle can be adjusted, but it is difficult to secure the rigidity of the whole workpiece attaching device
Solution Approach 1:
The patent segments the workpiece attaching device into distinct functional modules: the rotating table for rotational movement, the pivot section for inclination adjustment, and the workpiece attaching section for holding the workpiece. This segmentation allows each component to perform its specific function optimally while maintaining overall device rigidity through proper connection design.
Solution Approach 2:
The patent combines the pivot section with the rotating table structure, where the pivot section is integrated into the rotating table to provide both rotational support and inclination adjustment functionality. This merging reduces the number of separate support mechanisms needed while maintaining device rigidity.
3Adaptability or versatility
If the workpiece attaching section is supported by the rotating table via the horizontal shaft and the worm gear mechanism, then the inclination angle can be adjusted, but there is a constant backlash in the worm gear mechanism making it difficult to secure the rigidity
Solution Approach 1:
The patent replaces the worm gear mechanism with a pivot section that allows direct rotational movement for inclination adjustment. This substitution eliminates the inherent backlash problem of worm gear mechanisms while maintaining the ability to adjust the inclination angle smoothly and reliably.
4Extent of automation
If the worm gear mechanism and the servo motor are provided on the rotating table rotating about the vertical axis, then the inclination angle can be adjusted automatically, but the size of the whole workpiece attaching device becomes too large
Solution Approach 1:
The patent extracts the automatic adjustment functionality from the main rotating table structure by implementing the pivot section as a separate, compact mechanism. This allows the servo motor to be positioned in a space-efficient manner while maintaining automatic inclination adjustment capability without increasing the overall device size.

AI summary
The present invention facilitates with high accuracy the adjustment of a minute angle degree, and also is capable of sufficiently securing the rigidity of the whole device after the adjustment and provides good operability, accuracy, and rigidity. Provided are a workpiece attaching body having a workpiece attaching surface and a rotating body rotatably supporting the workpiece attaching body. The rotating body has an inclination angle adjusting surface inclined relative to an axis of the rotating body, the workpiece attaching body has opposite to the workpiece attaching surface an inclination angle adjusting surface which is inclined relative to the workpiece attaching surface and which comes in surface contact with the inclination angle adjusting surface of the rotating body, and spherical coupling means is arranged which is for rotatably adjustably coupling the workpiece attaching body and the rotating body about a spherical center on an axis of the rotating body along both inclination angle adjusting surfaces. Thereby, the rotating body and the workpiece attaching body are relatively rotated about the spherical center along both inclination angle adjusting surfaces so as to adjust the inclination angle of the workpiece attaching surface.
