Outer Periphery Polishing Apparatus with Adjustable Tilt Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outer periphery polishing apparatuses are limited in their ability to polish workpieces with varying bevel angles, as they have fixed tilt angles and reciprocation lines, making them incompatible with workpieces having different edge angles.
Innovation Solution
An outer periphery polishing apparatus with adjustable tilt angles for both the polishing member and the reciprocation line, allowing the working surface to be parallel to the edge of the workpiece, enabling the polishing of edges with different bevel angles using a chucking device, edge polishing units, and adjustment mechanisms for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the tilt angle of the working surface and the reciprocation line are fixed to a predetermined angle, then the polishing efficiency is excellent, but only workpieces having a bevel angle equal to the fixed tilt angle can be polished
Solution Approach 1:
The patent applies the dynamics principle by making the tilt angle of the working surface and the reciprocation line adjustable rather than fixed. The polishing apparatus includes mechanisms that allow the tilt angle to be dynamically changed to match different bevel angles of workpieces, while maintaining the surface-to-surface contact configuration that provides excellent polishing efficiency. This resolves the contradiction by enabling both high efficiency and adaptability to various bevel angles.
2Adaptability or versatility
If the tilt angle is adjusted to match different bevel angles, then workpieces with different bevel angles can be polished, but the configuration becomes fundamentally different from conventional apparatuses
Solution Approach 1:
The patent applies the universality principle by designing a polishing apparatus that can handle multiple types of workpieces with different bevel angles using a single device. The adjustable tilt angle mechanism and reciprocation line adjustment enable the apparatus to universally polish various edge configurations while maintaining the fundamental surface-to-surface contact polishing method, thus avoiding the need for fundamentally different configurations for different workpiece types.
