Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bore clamps are not optimal in terms of the drive mechanism for the clamping bolt, which can lead to inefficiencies and potential malfunctions due to the risk of chips or impurities entering the expanded clamping bush.
Innovation Solution
The bore clamp features a unique clamping bolt drive with a laterally displaceable piston and a wedge gear that converts lateral movement into axial movement of the clamping bolt, along with a cover cap on the clamping bolt to prevent foreign bodies from entering the clamping bush.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional axial piston drive is used for the clamping bolt, then the clamping process can be performed, but the drive mechanism is prone to contamination by chips and impurities entering the expanded clamping bush
Solution Approach 1:
The piston is displaced laterally (perpendicular to the clamping direction) instead of axially, converting the drive direction from the clamping axis to a lateral axis. This dimensional change positions the piston and wedge gear outside the expanded clamping bush, preventing chip and impurity contamination while maintaining effective clamping bolt actuation through the wedge mechanism
2Reliability
If the piston is displaced laterally to avoid contamination, then the drive mechanism reliability improves, but the device complexity increases due to the wedge gear mechanism
Solution Approach 1:
The wedge gear acts as an intermediary mechanism that converts lateral piston displacement into axial clamping bolt movement. This mediator component enables the beneficial lateral drive arrangement while achieving the required axial clamping action, balancing reliability improvement against the added mechanical complexity
