Crystal Orientation Adjustment Fixture for Precision Grinding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crystal orientation adjustment mechanisms in grinding devices operate roughly, resulting in large amplitude adjustments that fail to meet increasingly stringent requirements for precise crystal orientation.
Innovation Solution
A grinding apparatus with two crystal orientation adjustment fixtures, each comprising a fixing seat, an adjustment body, a first adjustment component, and a universal mandrel module, arranged diagonally on an adjustment plane to allow precise fine-adjustment of the to-be-processed object's crystal orientation by moving the adjustment bodies relative to the fixing seats along a specific direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional rough adjustment method (beating with rubber hammer) is used, then ease of operation is improved, but manufacturing precision deteriorates
Solution Approach 1:
The adjustment mechanism is divided into multiple independent adjustment components (first adjustment component and second adjustment component) that can be adjusted separately along different directions, allowing precise control of crystal orientation while maintaining operational simplicity
Solution Approach 2:
The rough mechanical beating method is replaced with a structured mechanical adjustment system featuring adjustment slots and adjustment components that provide controlled, precise movement without requiring forceful impact, thereby improving precision while maintaining ease of operation
2Ease of operation
If large amplitude adjustment is used, then ease of operation is improved, but manufacturing precision deteriorates
Solution Approach 1:
The adjustment system incorporates dynamic adjustment capabilities where the adjustment components can move along adjustment slots to achieve both large-range and fine-position adjustments, enabling the system to adapt between coarse and fine adjustment modes as needed
Solution Approach 2:
The adjustment mechanism operates in multiple dimensions through diagonally opposite adjustment components that can move along slots in different directions, allowing precise three-dimensional control of crystal orientation while maintaining operational simplicity

AI summary
A grinding apparatus and a crystal orientation adjustment fixture thereof are provided. The crystal orientation adjustment fixture includes a fixing seat, an adjustment body, a first adjustment component, and a universal mandrel module. The adjustment body is assembled to the fixing seat through a rear end surface thereof. The adjustment body has a universal slot recessed in a front end surface thereof and a first adjustment slot formed along an adjustment direction, and a bottom of the first adjustment slot corresponds in position to the fixing seat. The first adjustment component is movably assembled in the first adjustment slot along the adjustment direction and abuts against the fixing seat. The universal mandrel module is rotatably assembled in the universal slot. The first adjustment component is adjustable along the adjustment direction to move the adjustment body relative to the fixing seat along the adjustment direction.
