Multi-Socket Nut Tightening for Variable Shaft Pitch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nut temporary tightening devices face efficiency issues when dealing with workpieces that have varying shaft pitches, requiring the replacement of device parts to adapt, which decreases work efficiency.
Innovation Solution
A nut temporary tightening device with bearing parts, support plates, and socket assemblies that absorb variation in shaft pitch, allowing for temporary tightening of multiple nuts simultaneously, featuring adjustable support holes and sockets that can align with bolts of varying positions, and a gear system for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the shaft pitch is adjusted by replacing parts of the device, then the device can adapt to different shaft pitches, but the work efficiency decreases due to the trouble of replacing parts
Solution Approach 1:
The device employs movable support plates that can shift positions along the shaft to accommodate different shaft pitches. Instead of replacing parts, the support plates are designed to move dynamically, allowing the device to adapt to various workpiece configurations while maintaining continuous operation and high work efficiency.
Solution Approach 2:
The support plates are designed with multiple functions: they can be positioned at different locations along the shaft, accommodate multiple sockets, and adjust to varying shaft pitches. This universal design eliminates the need for part replacement while maintaining adaptability across different workpiece types.
2Device complexity
If multiple sockets are fixed at predetermined positions, then the device structure is simple, but it cannot adapt to workpieces with varying shaft pitches
Solution Approach 1:
The support plates are designed to move along the shaft rather than being fixed at predetermined positions. This dynamic positioning capability allows the device to maintain a relatively simple overall structure while achieving adaptability to different shaft pitches through the movable support mechanism.

AI summary
A nut temporary tightening device has bearing parts, a first support plate, a second support plate, and socket assemblies. Each bearing part has a cylindrical sleeve extending in an up-down direction and a flange provided at an intermediate portion of the sleeve. The first support plate has a plurality of first support holes that each support a corresponding bearing part along the outer circumference, on an upper end side, of the bearing part. The second support plate has a plurality of second support holes that each support a corresponding bearing part along the outer circumference, on a lower end side, of the bearing part. Each socket assembly has a driving shaft, a driving part, and a socket.
