Abstract

The invention discloses a self-adaptive underactuated robot clamping claw which comprises a clamping claw shell, a drive module and finger modules. The clamping claw shell comprises a front clamping claw shell body, a rear clamping claw shell body and a fixing flange, wherein the front clamping claw shell body and the rear clamping claw shell body are connected and are further in bolt connection with the fixing flange. The drive module is arranged in the clamping claw shell and comprises a drive motor, a power transmission device and drive rods. The drive motor is used for driving the drive rods to make synchronous linear motion and transmitting torque through the power transmission device. The finger modules comprise the first finger module and the second finger module which are each provided with a first finger section and a second finger section. Each first finger section and the corresponding second finger section are hinged to the corresponding drive rod through a self-adaptive connecting rod system and a parallel connecting rod system, and area driven to move through the drive rod. The self-adaptive underactuated robot clamping claw can grab objects in different shapes in different manners, is suitable for requirements of different occasions and high in clamping range and clamping force, and can grab the objects more conveniently.

Description

technical field [0001] The invention belongs to the field of robot grippers, in particular to an adaptive underactuated robot gripper. Background technique [0002] Most of the existing industrial grippers adopt the clamping method with parallel ends. This kind of clamping method has stable grip and low processing cost. However, they often can only grab specific types of objects with few degrees of freedom. The clamping method is a One-to-one grippers cannot grip other types of items; in order to solve this problem, grippers with adaptive gripping functions have emerged as the times require. The adaptive robotic gripper is designed to be more flexible. When grasping an object, it can perform parallel grasping or envelope grasping according to the geometric shape and location of the target object. Parallel gripping refers to the grasping of small-sized objects or larger objects with opposing surfaces, with the end segments of the gripper fingers kept parallel for gripping; e...
