Solution Overview
Problem
Conventional inclination angle adjusting systems in 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 incorporates a support with an obliquely inclined inclination angle adjusting surface and a movable body with a corresponding inclination angle adjusting surface, coupled via an inclination angle adjusting shaft, along with coupling means that enable rotation adjustment, and utilizes fluid pressure to cancel and regulate coupling between components, ensuring precise angle adjustments and enhanced rigidity.
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 operation is simple, but it is difficult to adjust a minute angle degree
Solution Approach 1:
The patent introduces a pivot section as an intermediary component between the rotating table and the workpiece attaching section. The pivot section includes a pivot shaft and a pivot bearing, allowing the workpiece attaching section to be swung about a horizontal axis while enabling precise angle adjustment through this intermediate mechanism rather than direct pivoting.
2Ease of operation
If the workpiece attaching section is supported on the rotating table via the pivot section and the height-adjustment screw mechanism, then the adjustment operation is enabled, but it is difficult to secure the rigidity of the whole workpiece attaching device
Solution Approach 1:
The patent segments the support structure into distinct functional components: a pivot section for angular adjustment and a height-adjustment screw mechanism for vertical positioning. This segmentation allows each component to perform its specific function optimally while maintaining overall device rigidity through proper structural design.
Solution Approach 2:
The patent employs a ball screw mechanism in the height-adjustment screw mechanism, utilizing spherical geometry to convert rotational motion into linear motion. This curved mechanism provides smooth, precise height adjustment while maintaining structural rigidity through the ball screw's inherent mechanical advantage.
3Ease of operation
If the worm gear mechanism and the servo motor are provided on the rotating table rotating about the vertical axis, then the workpiece attaching section can be adjusted, but the size of the whole workpiece attaching device becomes too large
Solution Approach 1:
The patent replaces the conventional worm gear mechanism with a ball screw mechanism driven by a servo motor. This substitution eliminates the need for bulky worm gears while achieving the same adjustment functionality, significantly reducing the device size. The ball screw mechanism provides precise control with a more compact footprint.
4Ease of operation
If the conventional adjusting systems are used, then the basic adjustment function is provided, but there is 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 ball screw mechanism that eliminates backlash. The ball screw's self-locking特性 and precision threading provide rigid, backlash-free connection between the servo motor and the workpiece attaching section, ensuring reliable and repeatable positioning.
