Clamping Tool Bushing With O-Ring Friction Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping tools for welding tables face issues with shifting forces that impair dimensional accuracy during clamping and lack the ability to easily adjust the direction of the clamping device.
Innovation Solution
A clamping tool with a bushing on the strut that includes a receptacle for the clamping device, featuring grooves and O-rings to inhibit rotational mobility, allowing for adjustable clamping direction and compensating for shifting forces, along with a vertical strut and adjusting ring for enhanced positioning and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the clamping device is mounted with separate components and axles to avoid harmful forces, then the dimensional accuracy is improved, but the ability to adjust clamping direction is lost
Solution Approach 1:
The clamping device is designed with a rotatable receptacle mounted on the strut, allowing the clamping direction to be dynamically adjusted by rotating the receptacle to different angular positions while maintaining the separate component mounting structure that prevents harmful forces
2Adaptability or versatility
If the holder for the clamping device is fixed in different positions with a screw, then the clamping direction can be changed, but the operation complexity increases
Solution Approach 1:
Instead of fixed positional adjustment with screws, the receptacle is designed to be rotatable about an axis perpendicular to the strut's longitudinal direction, allowing continuous angular adjustment of the clamping direction without requiring loosening and tightening of fasteners
Solution Approach 2:
The clamping direction is adjusted by changing the angular parameter of the receptacle's rotation position, enabling flexible direction control through a single rotational degree of freedom rather than multiple discrete positional adjustments
3Ease of operation
If the receptacle is freely rotatable in the bushing, then the clamping direction can be adjusted easily, but the set direction cannot be maintained against gravity
Solution Approach 1:
The O-ring is positioned in the bushing to create a preliminary restraining force against the receptacle's rotation, preventing the receptacle from rotating freely under the influence of gravity or other external forces once the desired clamping direction is set
Solution Approach 2:
The O-ring acts as an intermediary element between the receptacle and the bushing, providing a friction-based locking mechanism that maintains the receptacle's angular position while still allowing intentional rotation when force is applied
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 solution ensures maintained dimensional accuracy and allows for easy adjustment of the clamping direction within a 60° range, while being simple in structure and resistant to rough handling or contamination.
Implementation Method 1
the bushing having at least one groove in its interior as well as recesses for the clamping device and a the groove(s) slightly protruding O-ring inhibits the rotational mobility of the recording
Implementation Method 2
the guide can have at least one groove in its interior and an O-ring located in the groove(s) and slightly projecting beyond the groove(s) can inhibit the rotational mobility and/or longitudinal displacement of the strut
Implementation Method 3
The adjusting ring can have a groove in its interior and an O-ring located in the groove and slightly projecting beyond the groove can prevent the adjusting ring from being able to slide longitudinally on the strut

AI summary
The intention is to improve a clamping tool (1), comprising a brace (2), at one end of which a retainer (3) for a clamping device (4) is arranged, wherein the clamping device (4) can be pivoted about an axis extending perpendicularly to the longitudinal direction of the brace (2), in such a way that displacing forces that reduce the dimensional accuracy during clamping are avoided and simultaneously different directions in which the clamping device (4) acts can be set in a simple manner. For this purpose, the retainer (3) comprises a bush (5) arranged on the brace (2), in which bush a receptacle (6) for the clamping device (4) is rotatably supported, wherein the bush (5) has at least one groove (13) in the interior (12) thereof and holes (7) for the clamping device (4) and wherein an o-ring (14), which is located in the groove or grooves (13) and which slightly protrudes beyond the groove(s) (13) inhibits the rotational mobility of the receptacle (6).
