Bolting Tool Mounting Portion for Grip Length Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tools for fastening long bolts with lock nuts lack precision and accuracy in maintaining the set grip length during the fastening process, often resulting in misalignment and inconsistent tightening.
Innovation Solution
A bolting tool with a mounting portion that includes a bolt engagement portion, a nut engagement portion, and a coupling portion, which are coaxially aligned with a predetermined spacing, allowing for precise engagement and torque transfer to ensure consistent grip length during the fastening of a bolt assembly with a hexagonal socket head bolt and hexagonal nut.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional tools are used for fastening long bolts with lock nuts, then the fastening operation can be performed, but the grip length cannot be maintained with precision and accuracy
Solution Approach 1:
The patent introduces a specialized mounting portion as an intermediary device between the bolt assembly and the fastening operation. This mounting portion includes a bolt engagement portion, nut engagement portion, and coupling portion that work together to maintain precise grip length. The coupling portion acts as a mediator that couples the bolt engagement portion and nut engagement portion coaxially with predetermined spacing, ensuring accurate grip length maintenance during fastening operations.
Solution Approach 2:
The patent replaces conventional fastening tools with a specialized bolting tool that integrates the mounting portion directly into the tool structure. This substitution eliminates the need for separate measurement and adjustment operations, as the mounting portion inherently maintains the predetermined grip length through its coaxial coupling mechanism, thereby improving both precision and reliability.
2Reliability
If conventional fastening methods are used, then the operation can be completed, but misalignment and inconsistent tightening occur
Solution Approach 1:
The coupling portion serves as a precision intermediary that ensures coaxial alignment between the bolt engagement portion and nut engagement portion. By maintaining predetermined spacing and coaxial orientation, it prevents misalignment during the fastening operation, ensuring consistent and reliable tightening results.
Solution Approach 2:
The mounting portion is designed with predetermined spacing and coaxial alignment built into its structure before the fastening operation begins. This preliminary configuration of the bolt engagement portion, nut engagement portion, and coupling portion ensures that alignment accuracy is maintained throughout the tightening process, eliminating the need for real-time adjustments.
3Manufacturing precision
If the bolt and nut are engaged separately without a coupling mechanism, then assembly is simpler, but relative rotation occurs and grip length cannot be maintained
Solution Approach 1:
The patent merges the bolt engagement portion, nut engagement portion, and coupling portion into a single integrated mounting portion. This combination ensures that the bolt and nut are positioned with predetermined spacing and coaxial alignment, preventing relative rotation and maintaining grip length accuracy without requiring separate assembly steps or additional control mechanisms.

AI summary
Provided is a bolting tool that includes a mounting portion and a torque transfer portion. A bolt assembly is mounted to the mounting portion. The bolt assembly includes a bolt and a nut threaded onto a position along an external threaded portion of the bolt. The torque transfer portion transfers tightening torque to the bolt and the nut of the bolt assembly mounted to the mounting portion. The mounting portion includes a bolt engagement portion, which is engageable with a head of the bolt, a nut engagement portion, which is engageable with the nut, and a coupling portion, which couples the nut engagement portion to the bolt engagement portion coaxially and with a predetermined spacing therebetween.
