Tool Holder Chip Anchoring Against High-Speed Centrifugal Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool holders with built-in electronic chips face issues with centrifugal force causing the chip to be thrown out during operation, and previous solutions requiring additional components or altering dimensions to accommodate the chip are inadequate.
Innovation Solution
The tool holder incorporates form-fitting elements in the receiving trough and chip side walls, with a hardened adhesive forming a cohesive and positive connection, eliminating the need for a separate receiving sleeve and ensuring secure anchoring of the chip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a receiving sleeve is used to positively lock the chip in the receiving recess, then the chip is securely anchored against centrifugal force, but the radial space required exceeds the standard mounting area dimensions
Solution Approach 1:
The invention merges the receiving sleeve and the chip into a single integrated component. The chip itself is designed with an annular groove that serves as the receiving recess, eliminating the need for a separate receiving sleeve. This integration maintains secure anchoring capability while reducing the radial space requirement to fit within standard mounting area dimensions.
Solution Approach 2:
The chip is designed to serve multiple functions: it stores electronic data and simultaneously provides its own anchoring mechanism through the integrated annular groove. This multi-functionality eliminates the need for additional components like receiving sleeves, allowing the chip to be securely mounted within standard dimension constraints.
2Reliability
If a receiving sleeve is used to secure the chip, then the chip is positively locked, but an additional component is required increasing device complexity
Solution Approach 1:
The invention combines the chip and receiving sleeve into a single integrated component. The chip includes an integrated annular groove that serves as the receiving recess, eliminating the need for a separate receiving sleeve component. This reduces device complexity while maintaining secure positive locking capability.
3Ease of manufacture
If adhesive alone is used to mount the chip, then the mounting process is simple, but the chip can be ejected under high centrifugal force
Solution Approach 1:
The chip is pre-formed with an integrated annular groove during manufacturing. This preliminary action creates a built-in anchoring structure that works in conjunction with adhesive to prevent chip ejection under centrifugal force, while maintaining simple mounting procedures.
Solution Approach 2:
The mounting solution combines adhesive material with a mechanically interlocking structure (the annular groove). This composite approach integrates chemical bonding with mechanical retention, providing both ease of manufacture and reliable chip retention under high centrifugal force.
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
This solution provides high speed stability up to 200,000 rpm without risking the chip's ejection, maintaining compatibility with standard dimensions and eliminating the need for additional components.
Implementation Method 1
The side wall of the receiving recess for the electronic chip has first positive-locking elements to anchor the electronic chip positively in the receiving recess of the tool holder
