Balancing Adapter Fluid Braking for Jerky Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balancing or measuring adapters often result in jerky movements and uncontrolled ejection of components due to the need to overcome additional forces applied by centering elements, leading to undesired ejection, especially when air pressure is used.
Innovation Solution
Incorporation of a braking device with fluid brakes to control the movement of the clamping element, ensuring a constant advance speed and reducing impact speed and rebound during component ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the forces of the tongs actuation unit are increased to overcome the additional forces applied by the centering elements, then the clamping force is improved, but the movement of the tongs actuation unit becomes jerky
Solution Approach 1:
A braking device is introduced as an intermediary element between the tongs actuation unit and the clamping element. This braking device includes a brake piston and brake chamber that generate a controlled braking force to dampen the jerky movements caused by the interaction between the high clamping force and the centering elements, thereby smoothing the actuation process while maintaining the necessary clamping force.
2Ease of operation
If air pressure is used to eject the component, then the release process is simplified, but uncontrolled ejection and rebounding occur
Solution Approach 1:
The braking device applies a preliminary counteracting force during the ejection process. When air pressure is used to eject the component, the braking device's brake piston generates a controlled resistance that prevents uncontrolled ejection and rebounding, while still allowing the release process to proceed with the simplicity of air pressure actuation.
3Manufacturing precision
If additional centering elements are provided to radially pretension the components, then the centering precision is improved, but the forces required for actuation are increased
Solution Approach 1:
The braking device serves as a mediator that allows the system to maintain high centering precision through additional centering elements while managing the increased actuation forces. The braking device controls the movement dynamics, enabling the system to overcome the forces from multiple centering elements without causing jerky movements.
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 fluid brakes absorb kinetic energy, preventing jerky movements and uncontrolled ejection, allowing for precise clamping and release of components without impact.
Implementation Method 1
Kinetic energy can be absorbed by the braking device and the impact speed of the clamping element when the components to be balanced or measured are ejected can be reduced. In addition, rebounding of the moving masses can be avoided.
