Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for swaging a deformable collar onto an externally grooved member, such as bolts or lockbolts, face challenges in accurately aligning and engaging the grooves, leading to inefficient collar engagement and potential misalignment.
Innovation Solution
A hydraulically-powered hand-held tool with jaw means and swaging means that includes automatic axial position adjustment to ensure correct alignment of grooves, allowing for precise engagement of the collar with the grooved member by applying axial force and using a cam plate to adjust the jaw position if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual alignment methods are used to align jaw grooves with member grooves, then the alignment process becomes time-consuming and imprecise, but the device structure remains simple
Solution Approach 1:
The jaw means incorporates automatic axial position adjustment means that enables the jaw grooves to self-align with the member grooves through relative axial movement. The system uses the existing grooves and cam mechanism to automatically achieve precise alignment without requiring external manual intervention or complex alignment procedures, thus improving both precision and speed.
Solution Approach 2:
The automatic axial position adjustment means is pre-configured with cam surfaces and adjustment mechanisms that prepare the jaw means for alignment before the swaging operation begins. The cam plate can be pre-positioned to ensure that when the jaw means closes onto the member, the grooves are already aligned, eliminating the need for time-consuming manual alignment during operation.
2Adaptability or versatility
If fixed jaw position is used, then the device structure is simple, but the grooves cannot be correctly aligned when axial position varies
Solution Approach 1:
The jaw means transitions from a fixed position to a dynamically adjustable position through the automatic axial position adjustment means. The cam plate and associated mechanisms allow the jaw means to move axially relative to the swaging means, enabling adaptation to different axial positions of the member while maintaining a relatively simple overall device structure.
Solution Approach 2:
The cam plate serves as an intermediary element between the jaw means and the swaging means, facilitating axial position adjustment. By introducing this intermediate component, the system achieves position adaptability without requiring complex direct coupling mechanisms between the jaw means and the main body, thus balancing versatility with structural simplicity.
3Manufacturing precision
If precise groove alignment is achieved through manual adjustment, then alignment accuracy improves, but the operation becomes more complex and time-consuming
Solution Approach 1:
The system employs automatic axial position adjustment means that enables the jaw means to self-align with the member grooves through relative axial movement. The cam mechanism automatically positions the jaw grooves to match the member grooves during the closing action, eliminating the need for manual alignment operations while maintaining high precision groove engagement.

AI summary
A manually held hydraulically and pneumatically powered swaging tool for swaging a collar (35) onto a grooved or threaded bolt (36) includes jaws (39) having internal grooves (40) which match the groove (20) on the bolt. The jaws (39) are openable to receive the projecting portion of the bolt (36) and are closable to engage the bolt. An anvil (26) outside the jaws is axially movable by hydraulic means forwards over the jaws to lock them into engagement with the bolt, and then to force the anvil over the collar (35) to swage it to the bolt. The tool includes a detection rod (40) for detecting when the bolt (36) has been fully inserted into the open jaw (39). Thereby to initiate closure of the jaws by pneumatic means. Also, initial forwards movement of the anvil (26) is arranged to move the jaws axially forwards by an appropriate small distance, if this is necessary to axially align the grooves (40) on the jaws correctly in relation to the groove (20) on the bolt to enable closure of the jaws.
