Alignment Mounting Plate With Force Cancellation for Pin Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional alignment devices are limited in their application due to the inability to cancel forces in the first direction, which restricts their posture and usage, especially when gripping or inserting objects with horizontal central axes, leading to positioning errors and failure in gripping or inserting pins into horizontal insertion holes.
Innovation Solution
An alignment device with a support base, a movable mounting plate, a first holding mechanism for locking reference axes, and a second holding mechanism that cancels forces applied to the mounting plate using a fluid pressure actuating mechanism, allowing the mounting plate to transfer radially and maintain alignment functionality even when forces are applied in the first direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the alignment device is in the non-holding mode to allow radial transfer for absorbing positioning errors, then the positioning error absorption capability is improved, but unexpected forces in the first direction are generated due to weight and load conditions
Solution Approach 1:
A second holding mechanism acts as an intermediary between the mounting plate and support base to cancel unexpected forces in the first direction. This intermediary mechanism prevents the weight and load-induced forces from causing unwanted radial transfer while still allowing controlled alignment movement when needed.
Solution Approach 2:
The device changes the force balance parameters by introducing a counteracting force mechanism. The second holding mechanism dynamically adjusts the force equilibrium, enabling the mounting plate to remain stable in the radial direction while maintaining the ability to transfer when alignment is required.
2Adaptability or versatility
If the alignment device allows the mounting plate to transfer radially for positioning error absorption, then the adaptability to different postures is improved, but the gripping and insertion accuracy deteriorates due to force-induced displacement
Solution Approach 1:
The second holding mechanism serves as a mediator that selectively enables or disables radial transfer based on operational conditions. It allows the mounting plate to adapt to different postures and absorb positioning errors while preventing force-induced displacement during critical gripping and insertion operations.
Solution Approach 2:
The alignment device transitions from a static connection to a dynamic one, where the second holding mechanism can switch between allowing radial transfer (for adaptability) and preventing it (for accuracy). This dynamic control enables the system to optimize performance for different operational phases.
3Device complexity
If the conventional alignment device is used without force cancellation capability, then the device complexity is reduced, but the usage scope is limited due to inability to handle horizontal posture objects
Solution Approach 1:
The second holding mechanism is introduced as an intermediary component that adds force cancellation capability. While this increases device complexity slightly, it dramatically expands the usage scope by enabling reliable operation with horizontal posture objects and various conveying device configurations.

AI summary
An alignment device has a support base attached to a conveying device, and a mounting plate to which a gripping member is attached, and the mounting plate is transferably abutted on a fastening holder that is fixed to the support base. A movable ring fixed to the mounting plate has a sliding part that is transferably engaged with the fastening holder. A first holding mechanism arranged between the fastening holder and the mounting plate locks the mounting plate to the fastening holder. A second holding mechanism provided between the fastening holder and the movable ring cancels a first-direction force of the mounting plate.
