A clamping robot automatically grasps and tightens the mechanism

Abstract

The utility model discloses an automatic grasping and tightening mechanism of a clamping robot, which comprises a manipulator and a tightening structure, wherein the manipulator and the tightening structure are respectively connected to a manipulator arm. The utility model has a reasonable structure and a novel design. When in use, the robot identifies a tubular structure on an object to be processed, controls the manipulator to grasp the tubular structure and fix it, and then the robot identifies a structure that needs to be tightened and fixed on the object to be processed. For example, when a hexagonal wrench needs to be used to lock the object, the robot controls a first motor to operate, rotates the hexagonal wrench to a tightening position, drives a second motor connected thereto to move through an electric push rod, thereby pushing the hexagonal wrench to move, and drives the hexagonal wrench to rotate through the operation of the second motor for tightening. The utility model can be used in a variety of working conditions and has strong applicability.
