Link Clamp Housing Rotation Without Vertical Clamp Arm Shift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional link-type clamping devices experience vertical displacement of the clamp arm when changing the clamping position, disrupting the preadjusted horizontal state and accuracy of the clamping position.
Innovation Solution
A link-type clamping device with a turning-supporting member that allows the housing to turn to a desired angle while maintaining the axis constant, using a bolt to fix the housing at the desired position, and incorporating a receiving member to manage upward forces, ensuring the clamp arm remains at a constant vertical position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the supported member turns with respect to the support part by fitting the male screw region and female screw region, then the clamping position can be changed to a desired turning angle position, but the clamp arm becomes displaced in the vertical direction
Solution Approach 1:
The patent introduces a support part as an intermediary component between the housing and the supported member. The support part includes a receiving means that receives the upward force from the link member, and the supported member is supported by this support part. This intermediary structure allows the supported member to turn about the axis of the supported member without causing vertical displacement of the clamp arm, as the support part absorbs and manages the vertical forces during the turning operation.
2Ease of operation
If the clamp arm is turned to a desired turning angle position, then the clamping position is changed, but the preadjusted horizontal state is disrupted
Solution Approach 1:
The support part acts as a mediator that maintains the horizontal state stability during position adjustment. By providing a stable support surface and receiving the upward force through the receiving means, the support part ensures that the clamp arm can be turned to different angular positions without disrupting its preadjusted horizontal alignment.
Solution Approach 2:
The patent implements preliminary action by preadjusting the horizontal state of the clamp arm before the turning operation, and the support part is designed to maintain this preadjusted state throughout the turning process. The receiving means is pre-configured to receive the upward force in a way that preserves the horizontal alignment during the subsequent turning operation.

AI summary
A clamping device (2) includes: a turning-supporting member (26) formed so as to support a housing (3) which turns when a clamping position is set, the housing (3) turning toward a desired turning angle position about an axis of the housing (3) while maintaining the axis at a constant position; and a bolt (46) which fixes the housing (3) to the turning-supporting member (26) at the desired turning angle position.
