Tool Depth Setting Assembly for Precise Axial Cutting Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool assemblies for machining aircraft parts, such as chamfering or deburring, are complex and expensive, requiring cumbersome methods to determine and set the working depth with axial precision, making them difficult to handle and costly to maintain due to wear and tear.
Innovation Solution
A method involving a depth determination device with a mounting device that moves axially relative to the tool, using a contact surface and limit stop to set the cutting depth, allowing for easy and cost-effective adjustment of the working depth by applying a compression force, eliminating the need for complex adjustments and reducing structural complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a complex depth determination device with adjusting mechanisms is used to precisely set the cutting depth, then the measurement precision and manufacturing precision are improved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent extracts the adjusting mechanisms from the depth determination device, leaving only the essential stop surface and mounting structure. The cutting depth is determined solely by the axial distance between the stop surface and cutting edge, without any additional adjusting components, thereby simplifying the device while maintaining precision
Solution Approach 2:
The depth determination device is designed as a simple, inexpensive component that can be easily replaced or adjusted. The device uses basic elements like a stop surface and mounting structure rather than complex mechanical adjustments, making it cost-effective and suitable for frequent tool changes
2Adaptability or versatility
If a complex adjusting mechanism is integrated into the depth determination device to modify cutting depth, then the adaptability is improved, but the device complexity and ease of operation worsen
Solution Approach 1:
The patent changes the fundamental parameter approach by using a fixed axial distance between the stop surface and cutting edge to determine cutting depth. Instead of adjusting mechanisms, the system relies on the predetermined geometric relationship, simplifying operation while maintaining adaptability through the depth setting device gauge
Solution Approach 2:
The depth setting device serves as an intermediary gauge that transfers the predetermined axial distance from its contact surface and limit stop to the tool's stop surface and cutting edge. This intermediary mechanism enables depth adjustment without requiring complex mechanisms within the depth determination device itself
3Manufacturing precision
If precise depth determination mechanisms are added to the tool assembly, then the manufacturing precision is improved, but the ease of manufacture and device complexity worsen
Solution Approach 1:
The patent removes complex depth determination mechanisms from the tool assembly, retaining only the essential stop surface and mounting structure. The cutting depth precision is achieved through the simple axial distance measurement rather than sophisticated manufacturing mechanisms, greatly simplifying fabrication
Solution Approach 2:
The depth determination device performs its own function through the inherent axial distance between the stop surface and cutting edge without requiring additional adjusting mechanisms or complex assembly procedures. The device determines its own cutting depth through this fixed geometric relationship
