Rotating Disc Clamping Device for Precision Retaining Clip Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for mounting retaining clips on line elements face challenges in achieving precise positioning due to rotational issues and tolerance problems, especially when dealing with non-round cross-sections or large diameters, and fail to ensure non-rotatable mounting.
Innovation Solution
The device employs two parallel disk elements that can rotate in opposite directions with central recesses for the line element, featuring clamping jaws integrated into the disk elements to securely hold the retaining clip, allowing for precise positioning and non-rotatable mounting by adjusting the disk elements' position relative to the line element, and includes a bundling head for easy tape wrapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single disc element with a central recess is used to position the retaining clip, then the device structure is simple, but the positioning precision and non-rotatable mounting cannot be achieved
Solution Approach 1:
The clamping device is divided into two separate disc elements (first and second disc elements), each responsible for specific positioning functions. This segmentation allows each disc to be optimized for its specific task, achieving precise positioning and non-rotatable mounting while keeping individual components manageable in complexity
Solution Approach 2:
The retaining clip acts as an intermediary element between the two disc elements. The clip is inserted into recesses in both disc elements and secured by clamping jaws, serving as the medium that connects and aligns the two discs relative to each other, thereby achieving precise positioning
2Reliability
If a pin or fir-tree profile is used to grip the retaining clip, then the clip can be held, but the clip may rotate during positioning
Solution Approach 1:
The clamping jaws are designed with asymmetric profiles that match the asymmetric shape of the retaining clip. This asymmetric design prevents rotational movement by ensuring that the clip can only be held in one specific orientation, eliminating the rotation problem while maintaining ease of operation through the automated clamping mechanism
Solution Approach 2:
The two disc elements are pre-positioned and aligned relative to each other before the retaining clip is inserted. This preliminary alignment ensures that when the clip is inserted and clamped, it is automatically positioned in the correct orientation without requiring manual adjustment or risking rotation during positioning
3Strength
If the clamping jaws grip the retaining clip at the fir-tree profile, then the clip can be clamped, but the clip may twist within the clamping device
Solution Approach 1:
The clamping jaws are designed with specific local geometries that match corresponding features on the retaining clip. The jaws apply clamping force at multiple specific locations rather than a single point, distributing the force to prevent twisting while maintaining secure clamping. Each jaw's local geometry is optimized for its specific clamping function

AI summary
In a device for mounting a retaining clip (1) on a conductor element (2), a clamping device (3) has two disc elements (12, 13) rotatable relative to each other, with central recesses (16) for the conductor element (2). The disc elements (12, 13) each have a clamping jaw (14, 15) for holding the retaining clip (1). This enables the device to position the retaining clip (1) on the conductor element (2) with particular precision.
