A five-axis welding robot and its control method

Abstract

The invention provides a five-shaft welding robot and a control method of the five-shaft welding robot. The five-shaft welding robot comprises a base, a control system, a five-shaft mechanical arm and a welding machine, wherein the five-shaft mechanical arm comprises a first arm, a second arm, a third arm, a fourth arm and a fifth arm, and each arm is provided with a shaft, and a motor is arranged beside each shaft. According to the first arm, the second arm, the third arm, the fourth arm and the fifth arm, sequentially, each rear arm and the corresponding front arm are connected with the front arm as a fulcrum through the corresponding shaft, all the shafts are all movable shafts and driven through the corresponding motors, the motors are driven in the mode that a command signal is sent by a control system so that each arm can be controlled to execute movement, the control system further controls the welding machine, the welding machine comprises a welding gun, the welding gun is arranged at the free end of the fifth arm and moves along with the fifth arm, meanwhile, welding is executed and / or stopped under the control of the control system, the technical problems that an existing welding robot is poor in flexibility and large in occupied space and has dead angles are solved, and the five-shaft welding robot achieves the good effects that the five-shaft welding robot is convenient to manufacture and easy to operate, the yield of products is improved, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the field of welding, in particular to a five-axis welding robot for welding and a control method thereof. Background technique [0002] Automated welding robots have been widely used in the existing technology, which greatly improves the welding efficiency and accuracy while ensuring the safety of operators. However, most of the welding robots in the prior art have a single structure, and there are dead angles in the welding process. At present, what needs to be solved urgently in the industry is a welding robot that is flexible, takes up little space, is convenient to manufacture, is easy to operate, and makes welding without dead ends through the rotation of the mechanical arm. Contents of the invention [0003] In order to solve the above technical problems, the main purpose of the present invention is to provide a five-axis welding robot and its control method. [0004] In order to achieve the above object, the technic...
