Grindstone Truing Tool Yoke and Feeding Rod Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing truing tools for grindstones require manual adjustment and operation, leading to inconsistent results and are cumbersome due to their two-piece design, which complicates mounting on grinding machines.
Innovation Solution
A truing tool with a plate-shaped yoke and threaded feeding rod, guided by a universal support and adjustment nut, allows for precise setting of cutting depth and transverse feeding via operating knobs, enhancing stability, accuracy, and simplifying operation by eliminating the need for manual handling and separate parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a two-piece truing tool design is used, then the tool can be adjusted manually for truing operations, but the mounting on the machine becomes more difficult and parts may be lost
Solution Approach 1:
The patent combines the holder and mounting components into a single integrated truing tool assembly. The holder is provided with a through-hole that receives the universal support, eliminating the need for separate mounting parts and reducing the risk of losing components while maintaining manual adjustability through the threaded feeding rod mechanism
2Ease of operation
If manual adjustment is used for cutting depth, then the operator can control the truing process, but the accuracy and consistency of results depend on manual skill
Solution Approach 1:
The patent replaces pure manual adjustment with a threaded feeding rod mechanism that provides controlled, repeatable movement. The threading mechanism converts rotational motion into precise linear displacement, enabling accurate cutting depth control while maintaining operator control through the operating knobs at the ends of the feeding rod
3Device complexity
If the holder is not guided properly, then the tool structure is simpler, but the stability and accuracy of the tool during operation is reduced
Solution Approach 1:
The patent introduces the universal support as an intermediary guiding element that passes through the holder. This universal support acts as a stable reference and guide, constraining the holder's movement and providing the necessary stability and accuracy during truing operations while maintaining a relatively simple overall structure

AI summary
A truing tool for a grindstone (1) is intended for attachment to a universal support (3) of a grinding machine in parallel with the rotation axis of the grindstone. It has - in a holder (12) therefore - a cutting tip (13) for truing engagement with the grindstone. The holder (12) is movably connected to a yoke (10) - to be attached to the universal support (3) - by externally operated means (14, 15) on the yoke for its movement in relation to the yoke transversely of the grindstone (1).
