Abstract

The invention discloses a humanoid mechanical finger structure based on shaft drive transmission. The structure comprises a first knuckle, a second knuckle 28, a third knuckle and a base, each knuckle achieves linkage with the prior knuckle through the corresponding coordination of different crown gears and different straight gears, power driving the knuckles to rotate is transmitted forwards step by step from a direct current motor in a shaft drive transmission mode, and bending and stretching of a mechanical finger are achieved. In the humanoid mechanical finger structure based on the shaft drive transmission, the shaft drive transmission is adopted to transmit the power, fast movement of the mechanical finger can be achieved, and it is only required that a rotation motor drives the mechanical finger.

Description

technical field [0001] The invention belongs to robot technology, and in particular relates to a humanoid mechanical finger structure based on shaft transmission, which is used for grasping objects by a mechanical hand. Background technique [0002] With the advancement of science and technology, manipulators are widely used in industrial production, dangerous environment operations, and prosthetics for the disabled. Because the humanoid manipulator with five fingers and palms like a human hand has extremely strong functionality and high versatility, Therefore, it can completely replace human hands to complete various complex and dexterous operations on many occasions. During the operation of the manipulator, the objects are mainly grasped by the manipulator fingers. Therefore, the dexterous manipulator fingers with high precision, high flexibility and large torque output have important application value and practical urgency. [0003] Most of the existing artificial finger...
