Abstract

The invention provides a multi-freedom-degree motion automobile welding robot composed of an executing mechanism auxiliary chain and an executing mechanism main chain. The executing mechanism main chain can move in a plane through a main arm control mechanism, and the space movement of a movable platform can be achieved through supporting of the executing mechanism auxiliary chain and the movementof a machine body. Control is achieved through the synthesized movement of the executing mechanism auxiliary chain and the machine body, and the space movement of a tail end welding executer is achieved through connection of two rockers of a main arm. The motion inertia of the tail end welding executer is small, the dynamics performance is good, and reliability is high. The mechanism has the beneficial effects of being compact in structure and simple in control. The work space is large, the gravity center of the mechanism moves backwards, and the multi-freedom-degree motion automobile weldingrobot can be applied to more occasions.

Description

technical field [0001] The invention relates to the field of robots, in particular to a multi-degree-of-freedom mobile automobile welding robot. Background technique [0002] With the development and progress of society and the improvement of people's living standards, the requirements for automobiles are also getting higher and higher. The level of automobile welding directly affects people's comfort. Most of the traditional automobile welding devices are welding robots connected in series. This series welding robot has small working space, poor mechanism power and poor reliability, which brings inconvenience to automobile welding and cannot meet the requirements of modern society. Therefore, a new type of automobile is urgently needed. welding device. [0003] The multi-degree-of-freedom mobile automobile welding robot provided by the present invention has the advantages of light weight, compact structure, good rigidity, large bearing capacity and large working space, wh...
