Adjustable Milling Tool Holder With Nested Interlock Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing milling cutters require multiple sizes for different applications, leading to increased costs and storage needs, while current adjustable solutions compromise on strength, stability, and precision.
Innovation Solution
A milling tool holder with two variably positionable holder parts and a spacer element, along with a locking mechanism, allows for adjustable milling width without sacrificing strength, stability, or precision, utilizing a nested interlock design for optimal torque transmission and adjustable cutting insert receptacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sizes of milling cutters are provided for different applications, then adaptability to different milling widths is improved, but storage costs and operational costs increase
Solution Approach 1:
The milling cutter holder is designed with two holder parts that can be variably positioned relative to each other, allowing a single tool to perform multiple milling width operations. The first holder part has two cutting insert receptacles, and the second holder part has two cutting insert receptacles, with the ability to adjust the milling width by positioning the second holder part at different locations along the longitudinal axis. This universal design eliminates the need for multiple dedicated milling cutters for different width requirements.
2Adaptability or versatility
If milling cutter width is made adjustable, then adaptability to different applications is improved, but strength and stability deteriorate
Solution Approach 1:
The milling cutter holder is segmented into two separate holder parts that can be independently positioned and locked. The first holder part and second holder part are connected through a locking mechanism that secures them at predetermined locations along the longitudinal axis. This segmentation allows for adjustable milling width while maintaining the structural integrity of each individual holder part, as each part can be optimized for strength independently.
3Adaptability or versatility
If milling cutter width is made adjustable, then adaptability to different applications is improved, but manufacturing precision deteriorates
Solution Approach 1:
The locking mechanism is designed to secure the second holder part at predetermined, pre-engineered locations along the longitudinal axis of the first holder part. These predetermined positions are manufactured with high precision during the manufacturing process, ensuring that when the locking mechanism engages, the milling width is set with accurate precision. This preliminary positioning action eliminates the need for complex adjustment mechanisms during operation, maintaining manufacturing precision.

AI summary
Milling tool holder which comprises a first holder part, a second holder part, and a locking mechanism. The first holder part comprises a first cutting insert receptacle for receiving a first cutting insert and a second cutting insert receptacle for receiving a second cutting insert. The second holder part which, for adjusting a milling width, is variably positionable with respect to the first holder part along a longitudinal axis, comprises a third cutting insert receptacle for receiving a third cutting insert and a fourth cutting insert receptacle for receiving a fourth cutting insert. The locking mechanism is configured to fix the first and second holder parts to the adjusted milling width. The first holder part and the second holder part are positioned with respect to one another in such a manner that the third cutting insert receptacle is arranged in the circumferential direction between the first cutting insert receptacle and the second cutting insert receptacle, and that the second cutting insert receptacle is arranged in the circumferential direction between the third cutting insert receptacle and the fourth cutting insert receptacle.
