Insulation treatment process and equipment for surface of electrode arm of electrode holder of suspension spot welding machine

The invention provides a surface insulation treatment process and equipment for an electrode arm of an electrode holder of a suspension spot welder, which comprises the following steps of: carrying out local insulation treatment on the electrode arm, removing oil, corroding and activating, plating chromium, winding a glass fiber rope and the like, electroplating a layer of hard chromium on the surface of the electrode arm, and winding the glass fiber rope. The problem of electrode arm shunting in the spot welding process is solved. The treatment process is easy to operate and high in automation degree, and the treated electrode arm insulating layer has good insulativity, abrasion resistance and cutting resistance, long service life and low repair cost. 本发明提供了一种悬挂点焊机焊钳电极臂表面绝缘处理工艺及设备，通过对电极臂进行局部绝缘处理、除油、腐蚀活化、镀铬、玻璃纤维绳缠绕等工艺步骤，在电极臂表面电镀一层硬铬，然后缠绕玻璃纤维绳，以消除点焊过程中电极臂分流的问题。本发明处理工艺操作简单，自动化程度高，经过处理的电极臂绝缘层具有良好的绝缘性、耐磨性、耐割性，使用寿命长，修复成本低。
