Balancing Adapter Collet Axial Movement Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balancing or measuring adapters have limited axial retraction paths due to fixedly mounted collets, restricting positional accuracy and reproducibility in clamping rotating components.
Innovation Solution
The adapter design allows the collet to move axially within the base body, enabling clamping tongues to radially extend and engage with a component's clamping groove, with additional axial movement for increased pull-in path, utilizing conical surfaces and compression springs for controlled clamping and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the collet is fixedly mounted on the base body, then the structure is simple, but the axial retraction path is limited
Solution Approach 1:
The collet is transformed from a fixed mounting to a movable mounting along the axial direction. The base body includes a collet recess that allows the collet to move axially relative to the base body during the clamping process, enabling an extended axial retraction path while maintaining structural simplicity.
Solution Approach 2:
The clamping process is divided into two distinct phases: a first clamping phase where clamping tongues move radially outward on the front clamping region, and a second clamping phase where the collet moves axially within the base body at the rear clamping area. This segmentation allows each phase to optimize for its specific function.
2Length of moving object
If the collet moves axially within the base body, then the axial pull-in path is enlarged, but the device complexity increases
Solution Approach 1:
The radial clamping motion and axial retraction motion are merged into a single actuating element. The conical actuating element simultaneously drives the clamping tongues radially outward while the collet moves axially within the base body, eliminating the need for separate mechanisms for each motion.
Solution Approach 2:
The actuating element serves multiple functions: it provides the conical surface for radial clamping force application, enables axial movement of the collet within the base body, and controls both phases of the clamping process through its geometric design.
3Ease of operation
If separate reset elements are used, then the clamping tongues can return to release position, but the number of parts increases
Solution Approach 1:
The clamping tongues are designed with elastic properties that enable them to automatically return to their release position after clamping. The elastic deformation and recovery of the clamping tongues eliminates the need for separate reset elements, reducing the total number of parts while maintaining the reset function.

AI summary
The invention relates to a balancing or measuring adapter (1) for clamping a component (2) on a rotating machine element of a balancing or measuring machine, which has a main body (4, 5) with a receiving opening (6) for the component (2) to be clamped, a collet chuck (11) arranged inside the main body (4, 5) with clamping tongues (26) for centrally clamping the component (2) and an actuator (12) axially adjustable between a clamp position and a release position for actuating the collet chuck (11). The collet chuck (11) is arranged inside the main body (4, 5) so as to be axially moveable such that, upon a displacement of the actuator (12) from the release position into the clamp position, in a first clamping phase the clamping tongues (26) of the collet chuck (11) move radially outwards, firstly to a front chucking area (27) allocated to the component (2) to be clamped, and that in a second clamping phase, the clamping tongues (26) move radially outwards with an axial movement inside the main body (4, 5) to a rear chucking area (28) allocated to the main body (4, 5).
