Collet Chuck Tool Holder With Isolated Clamping Rotor Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool holders for chip removing machining are bulky, difficult to manufacture, and service, with limited options for exchanging collet chuck components, leading to complex handling and potential loss of parts during maintenance or adaptation.
Innovation Solution
A tool holder design featuring a base body with a machine spindle interface, a tube extension, and a clamping rotor supported by a support seat element and axial thrust bearings, allowing for easy rotation and locking, and enabling the collet chuck to be exchanged for service or adaptation purposes without losing any parts, with a compact and oscillation-damped configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the clamping rotor is made thin-walled and filigree with a wide opening for collet chuck extension, then the tool holder achieves a compact configuration, but the manufacturing complexity and service difficulty increase
Solution Approach 1:
The tool holder is divided into separate functional modules: a base body, a collet chuck reception body that can be exchanged, and a clamping rotor. This segmentation allows the thin-walled clamping rotor to be manufactured separately with simplified processes while maintaining the overall compact configuration when assembled.
Solution Approach 2:
The collet chuck reception body is extracted as a separate exchangeable component from the base body. This allows the clamping rotor to be designed as a thin-walled structure without needing to accommodate service operations, as the reception body can be independently removed and replaced.
2Device complexity
If the collet chuck reception body is made non-exchangeable, then the structure is simplified, but adaptability and serviceability are reduced
Solution Approach 1:
The collet chuck reception body is designed with dynamic exchangeability - it can be easily removed and replaced through a simple connection interface. This provides adaptability for different collet chuck types while maintaining a relatively simple overall structure when a single configuration is in use.
3Ease of manufacture
If the support seat element is not secured in the base body, then assembly is simpler, but reliability and part retention are compromised
Solution Approach 1:
The support seat element is provided with securing features (such as retention protrusions or threading) that are pre-formed during manufacturing. This allows the element to be easily secured to the base body during assembly without complex additional operations, ensuring both reliability of retention and assembly simplicity.
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 tool holder achieves a thin, easy-to-manufacture and service configuration with improved oscillation damping and secure clamping, preventing unintentional release of the support seat element and allowing for efficient tool handling and maintenance.
Implementation Method 1
a bearing supported on the support seat element, the bearing axially supporting the clamping rotor

AI summary
A tool holder for collet chucks, wherein a clamping rotor for applying an axial force to a collet chuck is provided. The clamping rotor, including the two axial bearings of the clamping rotor, are accommodated in a tool holder main part, which is connected to a collet chuck receiving body that receives the collet chuck. In order to captively support the clamping rotor in the main part, a bearing seat element is screwed into the main part, said bearing seat element delimiting a receiving chamber for the clamping rotor towards the collet chuck receiving element. Thus, the clamping rotor is enclosed and held in the main part independently of the collet chuck receiving body. This creates new possibilities for the maintenance and adaptation of the tool holder under different conditions, and in particular the force flow emanating from the clamping rotor during a clamping process is kept away from the collet chuck receiving body, thereby improving the precision of the tool holder.
