Tool Holder Container for Vibration Damping and Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool holders with integrated damping systems often hinder the flow of cooling mediums, requiring complex attachment methods and dedicated tubes, which complicates the machining process and affects the performance of the damping system due to heat from the cutting process.
Innovation Solution
A container system with a tool holder design that allows for easy attachment and placement of vibration damping devices and sensors, while enabling the flow of cooling mediums through clearance areas between the container and the tool holder, thereby isolating the damping system from heat and simplifying installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a damping system is installed directly in a cavity in the tool, then vibration damping is achieved, but the cooling medium cannot be brought forward or requires dedicated tubes
Solution Approach 1:
The damping system is extracted from the solid tool structure and placed in a separate container that is inserted into a cavity in the tool holder. This allows the damping system to be isolated from the cooling medium delivery path, eliminating the need for dedicated tubes while maintaining vibration damping functionality.
Solution Approach 2:
The tool system is segmented into separate functional components: the tool holder with cavity, the container with damping system, and the cooling medium delivery system. This segmentation allows each component to perform its function independently without interfering with others, particularly allowing cooling medium to flow freely while the damping system remains in place.
2Reliability
If a capsule with damping element is placed at the forward end of the tool holder, then vibration damping is provided, but attachment becomes complicated and cooling medium cannot be brought passed the tool holder
Solution Approach 1:
The damping element is extracted from a separate capsule and integrated directly into a container that is designed to be simply inserted into a cavity in the tool holder. This eliminates complicated attachment processes while maintaining the damping function, and the container design allows cooling medium to flow freely around it.
3Stability of the object's composition
If the container is inserted in the cavity with tight fit, then stable localization is achieved, but cooling medium flow is hindered
Solution Approach 1:
The container is designed with specific local features including an outwardly directed flange that provides stable localization against the cavity wall, while simultaneously incorporating axial through-flow channels that allow cooling medium to pass through. This local quality differentiation resolves the contradiction between stable positioning and cooling medium flow.
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 system effectively brings cooling mediums to the cutting edge, simplifies tool installation, and reduces the impact of heat on the damping system, providing stable localization and protection for the container's content while avoiding the use of adhesives and complex tube systems.
Implementation Method 1
At least one recess for leading the cooling medium is made between the container and the cavity wall
Implementation Method 2
The elements may include sensors for monitoring for instance temperature, vibrations, forces or similar properties, or elements that imposes particular properties to the tool. Damping of vibrations is typically such a property.

AI summary
The present invention concerns a system with a container and a tool holder (20) with two ends (21, 22). One of the ends of the tool holder (20) is adapted for being secured to a machine tool and the other end is adapted for attaching a cutting edge or a cutting edge carrying unit. The tool holder (20) includes an internal cavity (23) surrounded by a cavity wall. The cavity (23) accommodates the container (1). One end (21) of the cavity (23) is adapted for connection to a supply for a cooling medium and the other end (22) is connected to an outlet for cooling medium. The cavity (23) furthermore includes an opening (25) for installation of the container (1). At least one gap for leading the cooling medium is formed between the container (1) and the cavity wall. Furthermore, it is described a container (1) for installation in a machine tool, and use of the container for accommodating one or several sensor for measuring parameters or for receiving a damping system.
