Clamping Device Linking Member Guide Slits Stroke
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clamping devices with a fork-shaped link restrict the stroke of movement, making them unsuitable for clamping wider instruments, as they restrain the to-and-fro movement of clamp seats.
Innovation Solution
A clamping device with a linking member pivotally connected to slide members, allowing extension and contraction, featuring guide slits with varying deviation angles and positioning teeth, along with main springs and an engaging member to facilitate wider clamping capabilities and stabilize the sliding motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fork-shaped link is used to connect clamp seats, then the clamping device structure is simplified, but the stroke of to-and-fro movement is restrained and cannot accommodate wider instruments
Solution Approach 1:
The clamp seat is divided into a fixed seat and a movable slide member. The slide member can extend outwardly along the link through guide slits, separating the positioning function (fixed seat) from the extension function (slide member). This segmentation allows the clamping range to be increased without complicating the overall link structure.
Solution Approach 2:
The guide slits are designed with specific deviation angles that constrain the slide member's movement path. By controlling the deviation angles of the guide slits, the slide member's extension distance is regulated, enabling the device to accommodate wider instruments while maintaining structural simplicity.
2Adaptability or versatility
If the slide members are allowed to extend outwardly for wider clamping, then the adaptability is improved, but the sliding speed increases and stability decreases
Solution Approach 1:
The deviation angles of the guide slits are specifically designed to change during the sliding process. When slide members extend outwardly, the deviation angles adjust to slow down the sliding speed and improve stability. This parameter change ensures controlled movement while maintaining adaptability for wider instruments.
3Manufacturing precision
If the guide slits have fixed deviation angles, then the manufacturing precision is improved, but the ability to control sliding speed and stability is reduced
Solution Approach 1:
The guide slits are designed with variable deviation angles rather than fixed angles. As the slide member moves along the link, the deviation angle changes dynamically, allowing control over the sliding speed and stability. This dynamic design maintains manufacturing precision while enabling speed control.

AI summary
A clamping device with a linking member, the linking member is pivotally connected with a first and a second slide member, the slide members can be extended outwards and contracted inwards; wherein when deviation angles of two guide slits of the linking member are sharp angles, the first and the second slide members are at their initiate positions, and when deviation angles of two guide slits are obtuse angles, the first and the second slide members are at their extending positions.
