Adjustable Weight Tool Holder for Chatter Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holders with vibration control mechanisms are difficult to adjust for optimal weight, leading to potential chatter vibrations during cutting processes.
Innovation Solution
A holder design featuring a base with a cavity accommodating adjustable weights, where the weights are positioned along the central axis and can be easily attached or detached, with a protrusion and recess configuration to ensure surface-to-surface contact, facilitating weight adjustment and enhanced vibration control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional vibration control mechanisms with fixed weight members are used, then the holder structure is simple, but the weight cannot be adjusted for optimal vibration control
Solution Approach 1:
The weight member is divided into multiple separable weight pieces that can be independently positioned and attached to the holder body at different locations, enabling flexible weight adjustment without redesigning the entire holder structure
Solution Approach 2:
The holder transitions from a fixed weight configuration to a dynamic, adjustable weight system where weight pieces can be repositioned along the holder body to optimize vibration control for different cutting conditions
2Reliability
If weights are made adjustable for optimal vibration control, then vibration control performance improves, but the device complexity increases
Solution Approach 1:
The weight member is segmented into multiple detachable weight pieces that can be independently positioned and attached to the holder body at different locations, enabling flexible weight adjustment without redesigning the entire holder structure
Solution Approach 2:
A fastening mechanism serves as an intermediary component that simplifies the attachment and detachment of weight pieces to the holder body, reducing the complexity of weight adjustment operations
3Adaptability or versatility
If multiple weight pieces are used for adjustment, then weight adaptability improves, but the manufacturing complexity increases
Solution Approach 1:
The weight member is segmented into multiple detachable weight pieces that can be independently positioned and attached to the holder body at different locations, enabling flexible weight adjustment without redesigning the entire holder structure
Solution Approach 2:
Multiple weight pieces are made with identical structures and attachment interfaces, simplifying the manufacturing process by using standardized components that can be produced in batches
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
The holder provides improved vibration control performance by allowing for easy weight adjustment, reducing the likelihood of chatter vibrations during cutting processes, and ensuring the weights remain securely positioned.
Implementation Method 1
When the holder rotates, the weights generate centrifugal force that presses them against the inner wall of the cavity
Implementation Method 2
A damping mechanism (vibration control mechanism) including weight members and an energizing member may be discussed

AI summary
A holder in a non-limiting aspect of the present disclosure may include a base having a bar shape extended from a first end to a second end along a central axis, and a first weight having a column shape and a second weight having a column shape. The base may include a cavity extended along a central axis. The first weight may be located in the cavity. The second weight may be located in the cavity and located closer to the second end than the first weight.
