Rod Guide Clamping Rocker for Stud Bolt Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rod guides require significant effort for assembly and disassembly on stud bolts with external threads, leading to increased burden on employees and difficulty in maintaining short assembly times during the installation of large numbers of such guides.
Innovation Solution
The rod guide features a stationary lateral contact surface and a clamping rocker with an additional contact surface opposite the stud axis, allowing for easy assembly by reducing the force required for attachment and enhancing security against axial removal, with a clamping rocker that springs outwards during assembly and can be easily disengaged for disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If retaining tongues are spring-loaded against the stud bolt to secure the rod guide, then the rod guide is firmly secured to the stud bolt, but considerable force is required for assembly and disassembly
Solution Approach 1:
The clamping rocker is designed as a movable, spring-loaded component that dynamically adjusts during assembly and operation. During assembly, the rocker deflects outward to allow easy engagement with the stud bolt threads. During operation, it automatically engages firmly to provide secure retention, and during disassembly, it can be manually displaced to release the connection.
Solution Approach 2:
The clamping rocker is pre-loaded with a spring force that prepares it for engagement. The spring force is stored in advance and automatically applied when the rod guide is mounted, eliminating the need for continuous manual force during operation while maintaining secure engagement.
2Reliability
If multiple retaining tongues are arranged around the stud bolt to provide secure fastening, then the rod guide is reliably fixed, but the assembly process becomes time-consuming and labor-intensive
Solution Approach 1:
The fastening function is segmented into two distinct phases: a preliminary engagement phase where the rod guide is easily positioned on the stud bolt, and a securing phase where the clamping rocker automatically engages to provide firm retention. This segmentation allows rapid initial positioning followed by automatic securing, eliminating the need for multiple manual retention elements.
Solution Approach 2:
The clamping rocker performs the securing function automatically through its spring-loaded mechanism. Once the rod guide is positioned on the stud bolt, the spring force automatically drives the rocker into engagement with the threads, providing self-securing without requiring additional manual operations or multiple retaining elements.
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
This design significantly reduces the effort needed for assembly and enhances the security of the rod guide against slipping during use, allowing for efficient and easy installation and removal from stud bolts.
Implementation Method 1
an additional lateral contact surface for the stud bolt is provided opposite the stationary contact surface with respect to the stud bolt axis, which is supported by a clamping rocker arranged to spring away from the stud bolt axis
Implementation Method 2
the clamping rocker, with its integrated contact surface, engages more firmly with the threads of the stud as the tensile force increases

AI summary
The guide (10) has a fixed lateral bearing surface formed on a channel side facing away from a guiding leg (12). Studs are formed between a fastening leg (11) and the fixed bearing surface. A clamping rocker (19) is resiliently connected at ends of U-legs with a structure of the guiding leg. The clamping rocker is supported with respect to a U-shaped side surface (22) for the studs. The clamping rocker comprises spring arms that are formed with the guiding leg. The clamping rocker comprises an outwardly projecting actuating projection on an opposite side of the side surface.
