gripping mechanism

By designing a selectively rotating gripping mechanism and utilizing wall sections of varying distances, the problem of uneven gripping force is solved, achieving stable gripping that adapts to changes in item size, protecting both the item and the mechanism. This design is suitable for robotic arms and surgical instruments.

AI Technical Summary

Technical Problem

Existing clamping mechanisms are prone to over-tightening or insufficient clamping force when dealing with items of varying sizes, which can damage the items or the clamping mechanism itself.

Method used

A clamping mechanism is designed, including first and second clamping members and a selectively rotatable actuating component. The clamping force is switched between clamping and releasing structures through the interaction of a third actuating surface with the first and second actuating surfaces. Over-tightening is avoided by utilizing the different distances of the inward and outward-facing wall portions.

Benefits of technology

It effectively avoids overtightening, protects items and gripping mechanisms, adapts to changes in item size, provides appropriate gripping force, and is suitable for precise holding of robotic arms and surgical tools.

Abstract

A clamping mechanism (1) includes: a first clamping member (3) having a first clamping surface (5) and a first actuating surface (7); and a second clamping member (9) having a second clamping surface (11) and a second actuating surface (13), wherein the second clamping surface (11) is configured to be opposite to the first clamping surface (5) and to hold an article (15) therebetween. The clamping mechanism also includes an actuating element (17) capable of selective rotation, wherein the actuating element (17) includes a third actuating surface (19). Selective rotation of the actuating element (17) in a first direction (21) causes the third actuating surface (19) to interact with the first actuating surface (7) and the second actuating surface (13), and thereby causes the clamping mechanism to change from a release configuration (23) to a clamping configuration (25), in which the first clamping surface (5) and the second clamping surface (11) apply a clamping force to the article (15).
