[0034] Working principle: When the life of the single-welding electrode ends, the worn electrode head is manually installed on the automatic grinding machine, which will use grinding wheels of different materials and sizes to grind the electrode head. The grinding wheel integrates processes such as rough grinding, fine grinding, and chamfering. First, from the perspective of welding, the surface roughness of the electrode head is required to reach a certain level, generally less than 3.2. Therefore, after rough grinding off 0.1mm - 0.2mm, fine grinding is carried out to improve the surface roughness of the electrode head, which is more conducive to welding. After grinding, the chamfering process is carried out at the edge of the electrode head, which can avoid causing surface damage to the material during welding.
[0035] This mechanism also realizes the automatic calibration function. In the horizontal direction, there is a tooling for installing the quick-change electrode head. Press the start button, and in the horizontal direction, it moves forward to find the screw to position the highest point section of the current electrode head. Then, the PLC controls the servo to automatically complete processes such as rough grinding, fine grinding, and chamfering. After grinding, it is not confirmed whether the equipment can be installed for production. Therefore, it is necessary to calibrate the ground electrode head. Calibration means that there is pressure-sensitive paper fixed by a spring mechanism in the vertical direction. The PLC will control the horizontally moving ground electrode head to press on the pressure-sensitive paper. If the entire contour of the electrode is on the pressure-sensitive paper, it can be confirmed that the grinding is okay, and this electrode head can meet the production requirements.
