Telescopic Tool Holder Locking for Shell Cutter Length Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drilling and stopping machines require tool holders of varying lengths to accommodate different diameter shell cutters, leading to inefficiencies and increased time as operators must change tool holders, which is impractical and time-consuming.
Innovation Solution
A tool holder with an adjustable length mechanism, featuring a main body and extension with a locking mechanism that can be selectively positioned to fix or change the tool holder length, allowing for easy adaptation to different cutting tool sizes without the need for multiple holders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple tool holders of different lengths are used to accommodate different diameter shell cutters, then the adaptability to different cutting tool sizes is improved, but the device complexity and operational time increase due to the need to change tool holders
Solution Approach 1:
The tool holder incorporates an adjustable length mechanism with a telescopic extension that can be moved between retracted and extended positions, allowing the tool holder length to be dynamically changed to match different shell cutter lengths without requiring multiple separate tool holders
Solution Approach 2:
A single tool holder design serves multiple functions by accommodating different shell cutter sizes through its adjustable length capability, eliminating the need for multiple specialized tool holders for different cutter diameters and lengths
2Adaptability or versatility
If multiple tool holders of different lengths are used to accommodate different diameter shell cutters, then the adaptability to different cutting tool sizes is improved, but the device complexity increases due to the need to manage and change multiple tool holders
Solution Approach 1:
The tool holder is divided into a main body and a telescopic extension that can be independently adjusted, allowing the length to be segmented and reconfigured based on the specific shell cutter being used
Solution Approach 2:
A single universal tool holder design replaces multiple specialized tool holders by incorporating an adjustable length mechanism that adapts to various shell cutter sizes, simplifying the overall system
3Manufacturing precision
If a fixed length tool holder is used, then the manufacturing precision and structural simplicity are improved, but the adaptability to different cutting tool sizes deteriorates
Solution Approach 1:
The tool holder transitions from a fixed structure to a dynamic adjustable structure, where the telescopic extension can be positioned at different lengths and locked in place, maintaining structural integrity while providing adaptability
Solution Approach 2:
The telescopic extension fits within or alongside the main body of the tool holder, allowing the adjustable component to be nested within the overall structure when not in use, maintaining a compact form factor

AI summary
A tool holder includes a main body defining a mounting end and a receiving end, the mounting end positioned opposite from the receiving end, the main body defining a main body bore extending into the receiving end toward the mounting end; an extension defining a tool head attached to a rod, the tool head defining a tool head end opposite from the rod, a tool holder length defined between the mounting end and the tool head end, the tool head configured to receive at least one cutting tool, the rod received within the main body bore; and a locking mechanism engaging the extension and the main body in a locked position, the locking mechanism being disengaged from either the main body or the extension in an unlocked position, the locking mechanism being selectively positionable about and between the locked position and the unlocked position.
