Grinding Machine Tool Setter with Precision Contact Discs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for setting the position of a support bar in a grinding machine for replicating the edge angle of tools are inaccurate and dependent on user skill, requiring manual wooden spacers that can be lost and are not adaptable to grindstones of different diameters.
Innovation Solution
A device with metal discs for defining contact points with the grindstone and a hole for connecting to the support bar, made of a plastic plate with optional additional holes and projections for tool protrusion, allowing precise adjustment and attachment to the grinding machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual wooden spacers are used to set the support bar position, then the device complexity is reduced, but the manufacturing precision and reliability deteriorate due to user skill dependency and risk of loss
Solution Approach 1:
The patent introduces a specialized setting device with precisely manufactured contact points that act as an intermediary between the support bar and grindstone. This device eliminates the need for user-crafted wooden spacers by providing a standardized, accurate positioning mechanism that ensures consistent support bar positioning regardless of user skill level.
Solution Approach 2:
The setting device creates a reproducible reference configuration by using precisely positioned contact points that define specific geometric relationships. This allows the optimal support bar position to be replicated consistently across different grinding operations and grindstone sizes, eliminating variability introduced by manual spacer fabrication.
2Device complexity
If wooden spacers are used for setting, then the device complexity remains low, but the adaptability deteriorates as different spacers are needed for different grindstone diameters
Solution Approach 1:
The setting device is designed with adjustable or interchangeable components that allow it to accommodate multiple grindstone diameters. The device can be configured for different grinding applications through adjustable support bar positions or interchangeable contact point assemblies, eliminating the need for multiple dedicated spacers for different grindstone sizes.
Solution Approach 2:
The setting device incorporates dynamic adjustment capabilities that allow the user to modify the device configuration for different grindstone diameters. This may include adjustable arms, movable contact points, or reconfigurable geometric relationships that adapt the device to various grinding scenarios without requiring completely different spacers.
3Manufacturing precision
If precise manual setting is attempted, then the manufacturing precision may improve, but the ease of operation deteriorates due to the awkward and time-consuming process
Solution Approach 1:
The setting device incorporates pre-calculated and pre-positioned contact points that have been designed in advance to provide the correct geometric relationships for optimal tool sharpening. This preliminary preparation of the positioning geometry eliminates the need for users to perform complex measurements and calculations during operation, making the setting process both accurate and simple.
