Description
Technical Field
The application relates to the technical field of resistance spot welding, in particular to a positioning clamp for spot welding.
Background
In recent years, high-strength steel sheets are increasingly used on automobile bodies in order to simultaneously meet the dual standards of reducing carbon emissions and improving automobile safety performance. Meanwhile, resistance spot welding is a main welding method of vehicle body parts. In general, in resistance spot welding, an electrode and a welded plate are perpendicular to each other, and an electrode inclination angle is 0 °, but in actual production, the electrode and the welded plate are not perpendicular to each other due to an error of equipment or the like, and the electrode inclination angle is greater than 0 ° and is in an inclined state, and in recent years, many researches have found that the electrode inclination angle has a significant influence on welding quality of resistance spot welding, for example, in resistance spot welding of a galvanized sheet, an LME (liquid metal embrittlement) crack is generated due to the presence of liquid zinc, and an increase in the electrode inclination angle tends to promote the LME crack. Therefore, research on the influence of the electrode inclination angle on the resistance spot welding performance is very important. However, at present, a fixed resistance spot welder commonly used in a laboratory cannot change an electrode inclination angle, and introducing a robot capable of changing an electrode angle into the laboratory increases experimental cost and reduces experimental efficiency, so that it is necessary to develop a fixture for resistance spot welding, which is used in the laboratory and can simulate a working condition that the electrode inclination angle is greater than 0 ° in actual production.
