Magnetic Positioning Key Assembly for Secure Cutter and Collet Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutter holder assemblies face challenges in securely fixing cutters and collets due to difficulties in confirming the orientation of abutting planes and the ease of separation of position keys, making assembly inconvenient.
Innovation Solution
A magnetic attracting position key is integrated into the cutter and collet assemblies, featuring a body with a protruding rod and magnets that magnetically attract the key seat, ensuring secure attachment and preventing separation, thereby enhancing assembly convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastener is used to fix the cutter by abutting against an abutting plane, then the cutter is secured in the cutter holder, but it is difficult for a user to confirm whether the abutting plane is facing the fastener from outside, making assembly inconvenient
Solution Approach 1:
The patent uses visual indicators (color-coded markings or transparent/colored portions) on the cutter and/or fastener that allow users to easily identify correct orientation and assembly status from outside the cutter holder, eliminating the need to disassemble or closely inspect internal abutting surfaces
2Reliability
If a position key is placed on a key seat in the cutter and inserted into a key way in the cutter holder, then the position of the cutter is fixed relative to the cutter holder, but the position key is easily separated from the key seat, making assembly inconvenient
Solution Approach 1:
The patent replaces the traditional mechanical position key system with a magnetic field-based positioning system. The magnetic field generates attractive force between magnetic components (such as a magnet in the cutter and a ferromagnetic material in the holder), securely fixing the cutter in position without requiring separate position keys that can be easily lost or misplaced
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The magnetic attraction ensures secure engagement of the cutter or collet within the holder, simplifying the assembly process and preventing accidental disengagement, thus improving the usability and stability of the cutter holder assembly.
Implementation Method 1
a magnetic attracting position key is mounted on and magnetically attracts on the cutter key seat
Implementation Method 2
The magnetic attracting portion is combined with the body and magnetically attracts the collet

AI summary
A positioning cutter/collet assembly has a cutter/collet and a magnetic attracting position key. The cutter/collet has a cutter/collet key seat recessed in an external annular surface thereof. The magnetic attracting position key is mounted on and magnetically attracts the cutter/collet key seat. The magnetic attracting position key has a body having a protruding rod and a magnetic attracting portion combined with the body and magnetically attracting the cutter/collet to prevent the magnetic attracting position key from separating from the cutter/collet.
