Design Of Control System For Automatic Welding Production Unit Of Oil-absorbing Flange

With the rapid development of Chinese economy,the demand of heavy machinery and equipment is increasing,and the oil-absorbing flange as an important part of the hydraulic tank,the market demand of it also increased.However,the current domestic oil suction flange welding using manual welding,product production efficiency and quality can not meet the market demand.So it is very important to design a stable and reliable oil suction flange automatic welding equipment.Based on the original equipment,the automatic loading and unloading manipulator,the rotary welding platform and the remote monitoring system are designed to realize the automatic welding of the oil suction flange.The main contents of this paper include:1.In order to expand the movement stroke and improve the control precision,the X-axis adopts the rack and pinion gear,Y(Figure),the Y-axis is equipped with the gears and gears.Shafting with screwdriver screw structure;selection with four-axis pulse output Wo River HCA8 series PLC for the robot's core controller for the control of stepper motors and sports cylinders and other implementing agencies.2.According to the welding speed and weld shape of the automatic welding machine,it is determined that the working mode of the welding platform is rotary,that is,when the stepping motor on the welding platform drives the welding piece to rotate for one week,the welding of a ring weld is completed.Each welding process of seamless convergence,the need for welding platform,loading and unloading robot and automatic welding machine with each other cooperate well.3.We complete the design of man-machine interface,by using the industrial touch screen.First of all,the design and design of the control;and then combined with the preparation of ladder,the design of the welding robot and rotary welding platform teaching system.4.According to the design requirements of the remote monitoring system,the S3C2440 is chosen as the master chip to complete the LINUX kernel transplantation,the driver rewrite and the application program design.The real-time display of the control unit and the running status of the monitoring system are realized by combining the power carrier communication network.5.According to the welding process,we adjust the running of the various parts of the beat and the movement of the robot trajectory to optimize in order to improve production efficiency.
