Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping devices for balancing adapters are complex to assemble and require multiple adapters to clamp objects from both inside and outside, leading to increased complexity and difficulty in adapting to different workpieces.
Innovation Solution
A clamping device with cone components integrated into the clamping body, allowing for pre-assembly and easy connection to a base body, featuring a disk-shaped spring element and clamping element that can be rotated to adjust clamping diameter, and a rod-shaped actuating element for effective weight savings and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate balancing adapters are used for internal and external clamping, then clamping versatility is improved, but device complexity increases
Solution Approach 1:
The balancing adapter incorporates both an internal clamping device (for clamping from inside) and an external clamping device (for clamping from outside) within a single adapter body. This allows the same adapter to handle different workpiece types by switching between clamping modes, eliminating the need for multiple specialized adapters and reducing overall device complexity.
2Reliability
If conical components are used for clamping adjustment, then clamping effectiveness is improved, but assembly complexity increases
Solution Approach 1:
The patent integrates the conical adjustment mechanism directly into the clamping body structure. The conical surfaces are formed as integral parts of the clamping elements rather than separate components, which maintains the effectiveness of conical adjustment while significantly simplifying assembly procedures and reducing the number of parts to be assembled.
3Adaptability or versatility
If multiple balancing adapters are required for different workpieces, then adaptability is improved, but loss of time increases
Solution Approach 1:
By incorporating both internal and external clamping devices in a single balancing adapter, the system allows operators to switch between different clamping modes without physically replacing adapters. This eliminates the time-consuming process of adapter replacement while maintaining the ability to handle various workpiece types.

AI summary
The invention relates to a clamping device for clamping an object, in particular a workpiece to be balanced, with a clamping device (25) for clamping the object, wherein the clamping device (25) has an adjusting device by means of which the clamping diameter (d) of a clamping body (27; 138; 155) of the clamping device (25) is adjustable, wherein by adjusting the clamping diameter (d) an object, in particular one placed on at least one support surface, can be clamped.According to the invention, the clamping body (27; 138; 155) has a disc-shaped spring element (31) that is resilient in the radial direction (r) and has a centrally arranged recess (37) that forms at least one spring element cone; the clamping body (27; 138; 155) has a clamping element (33) inserted into the recess (37) of the spring element (31) and having at least one clamping element cone corresponding to the spring element cone; and the adjusting device has an actuating device (87) by means of which the clamping element (33) can be displaced relative to the spring element (31), in particular in the clamping disc axial direction (x), such that the conical surfaces of the clamping element cone and the spring element cone move relative to each other and thus the spring element (33) can be clamped and/or released under the action of the conical surfaces in the radial direction (r). is.
