Clamping Device Inner Outer Shaft Tolerance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping devices struggle to compensate for component size tolerances during clamping, leading to inefficiencies in the clamping process.
Innovation Solution
A clamping device with a rotatably mounted clamping shaft featuring an inner and outer shaft connected rotationally, where the inner shaft is displaceably mounted radially within the outer shaft, and an adjustment element fixes the inner shaft's position relative to the outer shaft, utilizing a cylindrical journal and control mechanism to compensate for tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the inner shaft is rigidly fixed in the outer shaft, then the structural stability is improved, but the ability to compensate for component size tolerances deteriorates
Solution Approach 1:
The inner shaft is designed to be displaceable within the outer shaft rather than rigidly fixed, enabling dynamic adjustment to compensate for component size tolerances while maintaining structural stability through the adjustment element that fixes the inner shaft in a determined position relative to the outer shaft
2Adaptability or versatility
If the inner shaft is displaceably mounted in the outer shaft, then the tolerance compensation capability is improved, but the structural stability deteriorates
Solution Approach 1:
An adjustment element is introduced as an intermediary mechanism between the inner shaft and outer shaft, fixing the inner shaft in a determined position relative to the outer shaft. This intermediary component enables the displaceable mounting to compensate for tolerances while maintaining structural stability through the determined positional relationship
3Adaptability or versatility
If a complex adjustment mechanism is added to compensate for tolerances, then the tolerance compensation capability is improved, but the device complexity increases
Solution Approach 1:
The clamping shaft is segmented into an inner shaft and an outer shaft as separate components, with the inner shaft displaceably mounted in the outer shaft. This segmentation allows for tolerance compensation through the relative displacement capability while keeping the adjustment mechanism relatively simple and integrated into the shaft structure

AI summary
A clamping device has a rotatably mounted clamping shaft (2), a clamping element (1), and a control mechanism (3). The clamping shaft (2) is formed from an inner shaft (2.1) and an outer shaft (2.2) that receives the inner shaft (2.1). The outer shaft is connected to the control mechanism (3) to pivot the clamping shaft (2), via a lever arm (5). The inner shaft (2.1) is rotationally connected conjointly to the clamping element (1). The inner shaft (2.1) is fixed in position relative to the outer shaft (2.2) by an adjustment element (4) connected to the inner shaft (2.1).
