Clamping Arrangement for Weaving Machine Holders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping arrangements for weaving machines, particularly for elongated components like cloth supports and temples, face challenges in easy and damage-free fitting and removal due to the need for multiple bolts and potential deformation or damage during the tilting process.
Innovation Solution
A clamping arrangement featuring a positioning slot in the holder's clamping groove that holds the clamping element in place under gravity, allowing for transverse fitting and removal of the clamping element, ensuring the screw openings remain aligned and preventing deformation or damage, with a hexagonal clamping element providing a trapezoidal shape for secure alignment and easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple bolts are distributed over the longitudinal direction to fasten elongated components, then the clamping strength is improved, but the device complexity and ease of operation deteriorate due to the difficulty of screwing multiple bolts into the clamping element
Solution Approach 1:
The clamping element is divided into multiple segments along its longitudinal direction, with each segment having its own bolt reception opening. This segmentation allows bolts to be accessed and screwed independently at different locations without requiring complex positioning or tilting operations, thus maintaining clamping strength while improving ease of operation
Solution Approach 2:
The clamping element acts as an intermediary component between the elongated component and the holder. It provides a standardized interface with multiple bolt openings that simplifies the fastening process, allowing bolts to be screwed directly into the clamping element without complex alignment requirements
2Ease of operation
If the tilting movement is used to fasten the component between the clamping element and holder, then the ease of operation is improved, but the reliability deteriorates due to potential damage or deformation of elongated components and holder
Solution Approach 1:
The tilting movement operation is extracted and eliminated from the fastening process. Instead of tilting the elongated component, the clamping element is designed with bolt reception openings that allow vertical screwing operations, separating the positioning function from the fastening function and eliminating the risk of tilting-induced damage
Solution Approach 2:
The design preemptively prevents the harmful tilting movement by providing a alternative fastening mechanism. The bolt reception openings are positioned and oriented such that bolts can be screwed in vertically without requiring any tilting of the component, thus preventing potential damage before it can occur
3Strength
If the clamping element is arranged beneath the component, then the clamping strength is improved, but the ease of operation deteriorates due to the difficulty of accessing bolt reception openings for elongated components
Solution Approach 1:
The clamping element is segmented into multiple sections along its length, with each segment having independently accessible bolt reception openings. This segmentation allows workers to access and fasten bolts at different locations along the elongated component without needing to move or reposition the entire clamping element, maintaining clamping strength while improving accessibility
