以前我们使用点焊机焊接银触头时,由于电极头与金属电极(钼棒)采用螺纹连接,两者在工作时易产生粘合,电极磨损后无法更换,致使电极头报废,造成材料和加工费用的浪费。对此,我们对电极头的结构进行了改进,将原来的螺纹连接变为弹性夹紧连接(如图),即将电极头端部铣槽,使其具 In the past, when we used the spot welder to weld the silver contacts, the electrodes and the metal electrodes (molybdenum bars) were screwed to each other. Therefore, the two were easily bonded during work, and the electrodes could not be replaced after being worn. As a result, the electrodes were discarded, Waste of processing costs. In this regard, we have improved the structure of the electrode head, the original screw connection into a flexible clamping connection (Figure), the tip is about to mill the groove, so that
