Principles and advantages of automatic pipe welding machine
With the continuous development of the economy and society, the application fields of automatic welding machines are constantly increasing, and new types of automatic welding machines are emerging, such as straight seam automatic welding machines, circular seam automatic welding machines, and pipeline automatic welding machines. Then I will introduce the principle and advantages from the pipeline automatic welding machine.
(1) Architecture of automatic pipeline welding machine Each universal pipeline automatic welding machine, according to its function zone, usually consists of three interrelated parts: the total length of the robot arm, the control board, and the teaching system software. The total length of the robotic arm is the management mechanism of the automatic pipe welding machine. It consists of the controller, the transmission system organization, the automatic pipe welding machine arm, the bone joint, the tail end manipulator, and its internal controller.
Its daily task is to accurately ensure the position, posture and fitness of the end manipulator. The control board is the central nerve of the automatic pipe welding machine. It consists of computer system, mobile phone software and some special-purpose power circuits. Its mobile phone software includes control board system, special language for automatic pipe welding machine, kinematics of automatic pipe welding machine, mobile phone software for dynamic model, and automatic welding machine monitoring. Software, self-diagnosis of automatic pipe welding machine, mobile phone software for white maintenance, etc.
It solves all the information content and manipulates all its postures in the whole process of the pipeline automatic welding machine. The teaching system software is the interactive socket of the automatic pipe welding machine and people. During the whole teaching process, it will manipulate all the postures of the automatic pipe welding machine and send all its information content to the memory chip of the control board. It is essentially Is a dedicated mobile intelligent terminal.
(2) Kinematics of the automatic pipe welding machine arm The mechanical arm of the automatic pipe welding machine is composed of a plurality of rigid rod bodies connected by rotating or moving bone joints. It is an open-loop bone joint chain, and one side of the open chain is fixed to the base. The other end is optional. The tail end manipulator is installed. When the pipe automatic welder is in actual operation, the tail end manipulator developed at the front end of the arm of the pipe automatic welder must be in the same position and posture as the steel being processed. , And this part and posture is generated by the fitness exercise of several arm joints.
Therefore, in the servo control system of the automatic pipe welding machine, it is necessary to understand the relationship between the indoor space of the independent variable of each bone joint of the robotic arm and the position and posture of the end manipulator. This is the physical model of the automatic welding machine kinematics. After the geometric structure of the robotic arm of each pipeline automatic welding machine is clear, its kinematic solid model can be determined.
