Variable-Length Tool Holder for Fast Shell Cutter Changeovers
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 and effort for operators to change out tool holders during pipeline modifications.
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 out tool holders
Solution Approach 1:
The tool holder employs an adjustable length mechanism with a telescopic extension that can be extended or retracted to accommodate different shell cutter lengths. This dynamic adjustment capability eliminates the need for multiple fixed-length tool holders, allowing operators to quickly adapt the same tool holder to different cutting tool sizes without time-consuming changes.
Solution Approach 2:
The tool holder is designed as a universal device that can accommodate multiple shell cutter diameters and lengths through its adjustable extension mechanism. Instead of requiring separate tool holders for each shell cutter size, this single multi-functional tool holder serves all cutting tool sizes, improving versatility while reducing operational complexity.
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 maintaining multiple tool holders
Solution Approach 1:
The tool holder employs an adjustable length mechanism with a telescopic extension that can be extended or retracted to accommodate different shell cutter lengths. This dynamic adjustment capability eliminates the need for multiple fixed-length tool holders, allowing operators to quickly adapt the same tool holder to different cutting tool sizes without time-consuming changes.
Solution Approach 2:
The tool holder is designed as a universal device that can accommodate multiple shell cutter diameters and lengths through its adjustable extension mechanism. Instead of requiring separate tool holders for each shell cutter size, this single multi-functional tool holder serves all cutting tool sizes, improving versatility while reducing operational complexity.
3Reliability
If the tool holder length is fixed, then the reliability and precision of cutting operations are improved, but the adaptability to different cutting tool sizes deteriorates
Solution Approach 1:
The tool holder employs an adjustable length mechanism with a telescopic extension that can be extended or retracted to accommodate different shell cutter lengths. This dynamic adjustment capability eliminates the need for multiple fixed-length tool holders, allowing operators to quickly adapt the same tool holder to different cutting tool sizes without time-consuming changes.
Solution Approach 2:
The tool holder is divided into segmented components including a main body and an extension section that can be independently adjusted. This segmentation allows the extension length to be modified while keeping the main body stationary, enabling precise positioning for different cutting tools while maintaining overall system reliability.
4Adaptability or versatility
If the tool holder length is adjustable, then the adaptability to different cutting tool sizes is improved, but the device complexity increases due to the locking mechanism
Solution Approach 1:
The locking mechanism is designed to be self-contained and self-operating, allowing operators to adjust and lock the extension length without requiring additional tools or complex procedures. The mechanism serves itself by automatically maintaining the selected length position, reducing operational complexity despite the added adjustability feature.
Solution Approach 2:
The locking mechanism acts as an intermediary between the adjustable extension and the main body, providing a simple interface that translates operator input into stable length positioning. This intermediary component manages the complexity internally while presenting a simple user interface, balancing adaptability with ease of operation.

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.
