Embodiment Construction
[0015] A method for monitoring the pressure of a welding gun based on a resistance welding power source, which includes the following steps:
[0016] In the first step, the master station reads the welding status, set torque, and set pressure information through the resistance welding power supply, and stores these information and forwards it to the servo driver of the welding gun;
[0017] In the second step, the servo driver of the aluminum spot welding tongs controls the action of the servo motor according to the received command, and completes the pressure and position control of the aluminum spot welding tongs, so that the aluminum spot welding tongs are in accordance with the set pressure and pressure. Press time to weld the workpiece;
[0018] In the third step, the master station reads the real-time pressure and position information of the aluminum spot welding gun, and forwards these data to the resistance welding power source;
[0019] In the fourth step, the resistance weld...

The invention relates to the technical field of electric resistance welding machine, in particular to a method for monitoring the pressure of an electrode holder based on an electric resistance welding power supply. The method comprises the following steps that: first, a master station reads the information of welding state, setting torque and setting pressure through the electric resistance welding power supply, stores and forwards the information to a servo driver of the electrode holder; second, the servo driver of the electrode holder for aluminium spot welding controls a servo motor to act according to a received command, and completes the control of the pressure and the position of the electrode holder for the aluminium spot welding; third, the master station reads the data of real-time pressure, position information and the like of the electrode holder for the aluminium spot welding, and forwards the data to the electric resistance welding power supply; and fourth, the electricresistance welding power supply masters the information of the real-time pressure, the position and the like of the electrode holder for the aluminium spot welding according to the received data, andcontrols a welding process according to the information. According to the system and method provided by the invention, the pressure and position of the electrode holder for the aluminium spot weldingcan be monitored through the electric resistance welding power supply; and precise control of the welding process is realized.
Description
Technical field [0001] The invention relates to the technical field of resistance welding machines, in particular to a system and method for monitoring the pressure of a welding clamp based on a resistance welding power source. Background technique [0002] The inverter intermediate frequency DC resistance welding machine presses the workpieces of two different materials or the same material to be welded between the upper and lower electrodes, and passes the welding current through the working contact surface and adjacent areas. Resistance heat is a method of processing it to a molten or plastic state to form a metal bond. As the requirements for energy conservation and emission reduction continue to increase, more and more attention has been paid to automobile lightweight. Compared with traditional low-carbon steel, aluminum alloy can greatly reduce the weight of the car body and meet higher energy conservation and emission reduction requirements. Therefore, aluminum alloy has b...
