Sealed Coolant Tube Bridging in Tool Holders to Prevent Turbulence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool absorption systems, such as PSC tool intakes, suffer from coolant turbulence and sacking in the cavity, leading to reduced tool cooling efficiency.
Innovation Solution
The introduction of a bridging element within the coolant bore, which stabilizes the coolant flow by bridging the cavity between the coolant tube and the smaller diameter area, preventing coolant from flowing into the cavity and reducing turbulence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a coolant pipe is screwed into the first area with enlarged diameter to a limited depth, then the coolant pipe can be installed and coolant can be supplied, but a cavity is formed between the coolant pipe and the second area which causes turbulence and coolant settling
Solution Approach 1:
A bridging element is introduced as an intermediary component between the coolant pipe and the second area with smaller diameter. This bridging element seals the cavity formed by the limited-depth installation of the coolant pipe, preventing coolant from entering the cavity and causing turbulence. The bridging element acts as a mediator that connects the coolant supply path while eliminating the harmful cavity space.
2Ease of operation
If the coolant pipe is installed to a limited depth in the first area, then installation is simplified, but coolant accumulates in the cavity leading to reduced cooling efficiency
Solution Approach 1:
The bridging element serves as a mediator that seals the cavity between the coolant pipe and the second area, preventing coolant accumulation. This allows the coolant pipe to be installed at a limited depth for ease of installation while maintaining effective coolant flow to the tool, thus preserving cooling efficiency.
3Ease of manufacture
If a cavity is formed between the coolant pipe and the second area, then the coolant pipe can be installed with limited depth, but turbulence and coolant settling occur in the cavity
Solution Approach 1:
The bridging element is introduced as a mediator that seals the cavity formed by the limited-depth coolant pipe installation. It prevents coolant from entering the cavity space, thereby eliminating turbulence and maintaining uniform coolant flow composition from the first area to the second area.

AI summary
The invention relates to a tool holder (2) for, in particular force-fit, holding of a tool, in particular a rotary tool, and to a kit, in particular for such a tool holder.The tool holder provides a receiving body (6) which has a rotary axis (8), an interface (10) at the rear for receiving the tool holder in a work spindle of a machine tool, a receiving section (14) at the front for the force-fit retention of the tool, in particular the rotary tool, a coolant bore arranged along the rotary axis between the interface and the receiving section, by means of which coolant can be directed along the rotary axis from the interface to the receiving section and which has a first area (20) with a second area (22) adjoining it in the direction of the rotary axis towards the receiving section, wherein a diameter of the first area is larger than a diameter of the second area, and a coolant pipe (28) arranged in the diameter of the first area of the coolant bore.Towards the receiving section, a cavity (30) is formed in the receiving body, or in the first, enlarged section, between the coolant tube and the smaller diameter second section of the coolant bore. To improve the coolant flow—and thus the cooling of a tool—the tool holder is designed with a bridging element (32) that allows coolant flow and seals the coolant flow against the cavity.
