Abstract

The invention discloses a passive clamping mechanism coupled with gears and pulleys, which comprises a connecting assembly sequentially connected from top to bottom, a scissor pressing rod assembly, a clamping mechanism connecting assembly, a rack and pinion coupling synchronous belt transmission assembly, and a flexible fin The effect component; the connection component is connected with the external pressure rod; the scissor type pressure rod component converts the vertical displacement of the external pressure rod into the horizontal displacement of the end of the scissor type pressure rod component; the clamping mechanism connection component is a rack and pinion coupling synchronous belt transmission component and The flexible fin-ray effect component provides support and fixation; the rack-and-pinion coupling synchronous belt drive component drives the flexible fin-ray effect component to move when the scissor pressure rod component moves; the flexible fin-ray effect component is driven by the rack-and-pinion coupling synchronous belt drive component Clamp the surface of round tubular objects. The clamping mechanism of the present invention uses the external pressing force on the clamping mechanism as the driving source, and through the change of the internal mechanical structure of the mechanism, the clamping mechanism realizes passive clamping without additional driving force.

Description

technical field

[0001] The invention relates to the technical field of anthropomorphic robot hands, in particular to a passive clamping mechanism coupled with gears and pulleys. Background technique

[0002] The mechanical gripping mechanism designed to imitate the gripping function of human hands has been applied to all aspects of life. In order to increase the anthropomorphism of the hand, more joint degrees of freedom should be designed in the hand to increase the reliability of the mechanism, but the use of multi-drivers to control the clamping mechanism will increase the structural complexity, volume and weight of the mechanism; in addition, in order to better Accurately grasping complex shapes and fragile precision objects requires the gripping mechanism to have a certain degree of self-adaptiveness; the existing gripping mechanism often drives the clamping object continuously through the motor, and the installation of the motor and the use of electricity are in a cert...
